How long would we wait for the cell phone battery pack for Iphone technology breakthrough?
Even if the smart phone development has been recognized as to reach a peak, every year we can see a large number of technical and design changes, such as OLED screen, large screen design and so on.
Of course, no matter how these things change, we seem to have got used to the unchanged thing, that is, the battery pack for Iphone technology. The performance of the phone has increased, the image resolution has continuous improvement, technology for taking pictures is getting better and better, but there are not much breakthrough in the battery life.
Of course, we have ways to improve the battery pack for Iphone life, as long as we make bigger batteries, but this is the most rude way, as the phone is that big after all. Almost all technical researches can be solved by money and time. Battery technology is so important, isn’t it worth for the manufacturers to devote?
The solution sounds simple, but it's not. It is not the crux of the problem to invest a lot of money, hire the best scientists, and have enough patience. The problem is that creating a more energy-intensive battery pack for Iphone involves a whole new science area.
In this regard, Billy Wu, a professor of the Dyson School of Engineering in London's Imperial College, explains that Moore's Law simply means that transistors will become smaller every few years, allowing the chip to accommodate more and thus increase its processing ability.
It is not such the case for the battery pack for Iphone area. "In the field of microprocessors, everything is just to make things smaller, but as for the lithium-ion battery, if you want to increase the energy density, in other words to increase your phone's Iphone battery pack life, then you have to basically change the material in the cell battery. "
This is not as simple as "then change materials," because even a slight imbalance of the internal material composition can cause serious problems.
So many accidents nowadays are reminding us how serious the incident will be. Professor Wu said that the existing nickel, cobalt and manganese combination may change in the next few years. Because nickel is more active, its proportion would get higher so as to increase its electricity consumption.
Of course, this single change will still take years of testing to ensure that everything is stable and safe. It is said that if successful, battery pack for Iphone life can be 10% to 20% upgrade. However, people have been waiting for so many years, while the promotion does not seem to match the time. As for a real breakthrough in battery technology, it is as if people are chasing an impossible dream.
Then the question is: Since the progress of the breakthrough has been so slow, when can we see the progress coming? Interestingly, the answer is long after, but it doesn’t seem so long.
It takes about 10 years and £100 million to develop a new chemical process. Moreover, 10 years is the first stage. Next, it will take another 10 years to continuously test and improve until the new technology is safe and stable enough. Otherwise, it will not be commercialized.
Although the battery pack for Iphone technology cannot be broken within a short time, but after all, other technologies have made progress. As cell phone performance continues to increase, resolutions up to 4K are even harsh demands for energy optimization.
In this regard, 10 nanometer process or even 7 nanometer process has been on the agenda. OLED screen can effectively reduce energy consumption. Optimization at various software levels has also become a required course.

Why the phone will automatically shut down at low temperatures?
In fact, not so much the phone is afraid of cold than the battery cold, the general liquid electrolyte in the lithium battery electrolyte and gel electrolyte, no matter what kind of electrolyte, in low temperature environment, will lead to greater resistance, lithium Ion penetration performance worse, it will appear in the cold area of the battery 20% take-off situation, when the temperature returns to normal, the phone will return.
Relatively speaking, lithium batteries can be done to maintain good performance in low temperature environments, and simply to achieve good low-temperature performance is very easy, but the problem is difficult to both high and low temperature while ensuring performance, often resistant High temperature performance so low temperature performance will be worse. Due to the high probability of occurrence of high temperature scenes, such as chip heat, or in high temperature environment, etc., because of high temperature scenarios are more likely to cause irreversible performance degradation and safety issues. In the extremely low temperature environment, few people will play mobile phones, which will lead to cell phone manufacturers will value the battery high temperature performance, rather than low temperature performance.
Another reason is that due to soldering and other reasons, due to the mobile phone electronic products, the use of brazing process, the solder joints are extremely small and sophisticated, although now like a cell phone using micro-connection to ensure that circuit solder joints in low temperature environment Performance is maintained, but because of the phone's solder joints are too small, in harsh environments, there may be failure, which is why in low temperature environment, the phone will be the cause of failure, if the long-term use of mobile phones in low temperature environment, not Just the battery life will be reduced, and even the internal electronic components will be damaged.
It is because of lithium batteries, not just the phone killer, or a lot of other killer electronic equipment, then take the Heilongjiang Heihe region and Inner Mongolia Hailar these two places, the winter temperature can be reduced to a minimum of -30 ° , While a cellphone like the iPhone series, if blown outside for a while, reports that the temperature is too low to turn it into a brick, turning it on only after waiting to go home to get the phone's cold heart warm. And mobile phones like Android do not report the temperature when they encounter extremely low outdoor temperature, but their power consumption will drop like mercury.
Why the cell phone battery temperature decreases after the power consumption will increase?
Although the cell phone battery nominal normal operating temperature are more broad, but as the temperature decreases, lithium battery discharge performance will be significantly decreased, the discharge platform will be significantly reduced, the discharge capacity was significantly reduced. However, because of the different brands of battery performance, its low temperature resistance is also a certain difference, so theoretically about 30 ℃, different capacity, the same milliampere when the battery capacity changes in low temperature environment is unpredictable, but In general, as long as the temperature is above zero degrees Celsius, mobile phone battery capacity will not be significantly reduced.
In addition, the seemingly no online data on the temperature on the battery capacity of the official data, I also found only a brand of battery temperature-dependent capacity performance, we can refer to: when the temperature dropped to -30 ℃, the battery discharge capacity of 87.0% of the discharge capacity at room temperature, discharge average voltage is lower than room temperature 0.598V, and its stored energy is only about 70% of the normal environment, lithium-ion battery constant current charge capacity of only 14% of the total charge capacity Pressure charging time will become very long.
This shows that, in fact, the impact of very low temperature on the battery though very large, but not as we exaggerated the estimated 10 degrees below minus 10 degrees, the battery capacity should be more than 90% efficiency. And if we can try to avoid exposing the mobile phone when the ambient temperature is low, and try to keep the temperature of the mobile phone above zero degrees Celsius, after a period of use, the mobile phone's own heat will gradually make it work normally.

Christmas holidays to buy power bank, knowing that these six will not be cheated
With the widespread use of smart phones, we chat QQ, wechat, brush microblogging, watching movies, listening to music, etc., but the battery is not durable, usually full one without a day, and even some can only be used for a long time, which also makes power bank is widely used, but it is used as an essential but not commonly used electronic product in life. Many people have the idea of buying a power bank supply. Anyway, it takes a while for a holiday to go out for travel or work, Long, on the stalls will buy one just fine.
Popular said: not afraid of ten thousand, afraid of in case. You will buy power bank here, maybe your life will be safe. We should not catch the greed for the cheap and catch their own life! 2016 Spring Festival is approaching, in order to allow you to stay home on the way always keep in touch with family and friends and relatives, to buy yourself a power bank is very important, Pay attention to the following 6:00, you can buy back a practical, durable and secure power bank will not be pit.
1, choose a mobile shell fire power
Lithium battery power bank charging and discharging in the process of generating heat, which is why we use the power bank supply in the process of power bank will heat the reason. If the heat is too high, the plastic case may be ignited, causing an explosion. So the existence of the shell, not only beautiful, but also a good protective device.
At present the metal shell on the market, all have the fireproof function, and the ABS and PC two kinds of plastic shell of the material is only part of the fireproof function, but most are not, so in the choice, you can consider the preferred metal shell power bank.
2, buy a full range of certified power bank
Here we mainly look at the products are obtained by the international and domestic quality certification, we all know that electronic products should have a formal certification, consumers can check whether the product has third-party certification or certification is complete, to obtain the confidence of the purchase . Third-party product certification to confirm the product is in line with certain quality standards and safety requirements. Where to buy power bank to pay special attention to the following four certification: UN38.3, 3C, MSDS and ROHS certification, as long as the four certification is generally reliable.
3, the capacity to see demand
In order to attract users, many manufacturers have introduced a large capacity mobile phone, and some even large capacity to 20000mAh. But you know? The capacity of power bank is proportional to the volume. In other words, high-capacity power bank supply, the volume will be larger, covering children, not portable.
If the phone is not very much power consumption, the road is not far away, one day to add electricity, then 5000mAh capacity power bank enough. However, if you are traveling abroad for long periods of time, you need enough power to run the car. You do not have to worry too much about moving the power too much. You usually have to go backpacking when traveling out and no place to put power bank. The specific choice to see everyone's own needs.
4, priority brand
The principle of the structure of the power bank is basically the same, so it will not be as difficult as the election mobile phone, which configuration is hesitant what they need. Mainly look at the appearance, capacity and price and security. The first three mainly depends on personal preferences, and security, is definitely the preferred brand, after all, as we all know, there is a certain risk of cottage products, and brand products more secure.
So even if you spend a little more money, choose to buy brand power bank, to add a more secure security, value for money.
5, formal channels to buy
Now the brand cottage products is too much like, for those who do not have the professional knowledge of identification, through formal channels to buy, you do not have to worry about pit friends. And through regular channels to buy power bank, manufacturers, all kinds of parameters, certificates, invoices, etc. is very complete, after-sales convenience.
6, shop around
To choose a more cost-effective, safer power bank, whether you are in the store or on the e-commerce platform to buy, shop around is inevitable. If not for a product has a persistent pursuit, you can compare more than a few brands to see more models, look at the same color, capacity, shape of the power bank, which brand more performance and safer. Such a reasonable price to buy the favorite product, but also equivalent to get a good mood.
In short, the purchase of power bank, sloppy sloppy, as the saying goes, you get what you pay for. The same token, for example, let you spend a million Traveling all over Europe and spend 10,000 to Travel to one country , which one would you choose?

Detailed rechargeable lithium batteries in power bank
With the prevalence of large-screen smart phones, their own battery technology bottlenecks, more and less mobile phone standby time more than a day. This gave birth to a new product category - power bank
As the technology advances, 5000 mAh power bank is still the starting number. 8000,10000,15000 or even 20000 mA power bank abound. The current charge Po market is very chaotic, from tens of dollars to several hundred dollars, a variety of blind brands Akira blind eyes (a top domestic providers on the category of rechargeable treasure there are hundreds of brands). However, there are still many charging Po door inside. For example, its appearance, round, flat, long, square, flaky and even plush toys! There are also its standard differences, such as talking about the airport when the wind, rather than what we commonly call the milliampere. More and more functions, such as storage, wireless routing, card reader function and so on.
Discharge efficiency is the most important cell, it is how the same thing?
The current charge Bao batteries generally divided into 18650 batteries and polymer lithium-ion batteries.
Their appearance is also very good.Cylindrical, relatively heavy charge treasure are generally 18650 batteries.
Polymer lithium-ion batteries size, appearance can be customized design. For example, some very thin, weird appearance, tablet power bank.
Now there is a saying, 18650 batteries lower than the polymer lithium-ion batteries, always feel put a few rechargeable batteries in it. Is this true? Of course not!
WST which is 18650 batteries, do you think it will be worse thing? Battery points A, B, C level, if all A-level batteries, the same milliampere batteries discharge efficiency is almost the same. This argument is mainly to sell polymer lithium-ion batteries, high-priced vendors used to attack opponents marketing strategy. Everyone wants to know this.
So the so-called kind of batteries better myth does not exist. It is important that the battery level, to identify the maker brand, to ensure that the battery level.
Nominal 5000 mAh will be able to charge 5000 mA Well? Not necessarily! This is related to its charge-discharge efficiency. Most of the power to close to 76% of the conversion efficiency is already good. For example, 10000 mA can charge 7600 mA to your phone, it is a very good conversion efficiency.

Fast charging can ruin the phone battery? This is the wrong way for you
How to prevent battery aging?
Fast charge will not accelerate the battery aging? The answer is no
The above said fast charge is actually to increase the charger power, so that current and voltage increase, so if you do not add control will cause the battery to age. However, in addition to the oldest QC1.0 standards, the new version of the fast charge technology, are achieved through the handshake protocol higher voltage fast charge mode. For some phones that do not support fast charge technology, the charger will automatically reduce the charging efficiency even if a fast charge charger is used, to prevent accidental occurrence.
Fast charging can ruin the phone battery? This is the wrong way for you
When we understand the principle of fast charge, from a technical point of view, fast charge only enhances the input voltage when charging, the general battery maximum current control will be controlled within 6A, QC 4.0 is the voltage and current control to maximize, But also in a safe range, the battery is not damaged.
In general, the current cell phone fast charge technology does not accelerate the aging of the battery. On the contrary, the most fundamental cause of accelerated aging of the battery, or our poor charging habits.
Have to know the bad habit of charging
To charge bad habits, it is certainly inseparable from the above battery aging reasons. First of all, to use the original charger and charging cable, to avoid charging the charger but the quality of the charge of accidents. Charge current instability and other issues, often because of the quality of your equipment is not good enough.
Fast charging can ruin the phone battery? This is the wrong way for you
Frequent charging, but also easy to accelerate the consumption of battery life, and even lead to reduced battery activity, battery life and other issues shortened. Especially in the fast charge technology to join, although the charge in the early fast, but did not rush to 100% of the drawing line, resulting in multiple recharge, increasing the number of battery cycles, such a long-term use will reduce the battery Activity, thereby accelerating the battery's aging. Like pouring beer, pour faster, the greater the bubble, "all is a bubble," the beer is not really full cup, the same charge, fast charge after half of the slow charge is more important. So even if the use of fast charge, try to make the phone full of power and then cut off.
Fast charging can ruin the phone battery? This is the wrong way for you
In addition, the battery charging at high temperature and low temperature conditions also has a great damage. In everyday environments, while playing games while charging, often make the phone's temperature rise rapidly, high temperature environment to accelerate the battery's internal chemical reactions, thereby accelerating the battery aging. Therefore, I hope the battery is more durable, it is best not to use while charging. At the same time in extreme circumstances, it is best to let the phone back to normal temperature before charging.
Fast charge to our life has brought convenience and improve the quality of our lives. We should not resist it. Understand the truth, get rid of bad habits when using, in order to better enjoy life.

Mobile phone battery power and then recharge the battery better?
Each time you buy a new cell phone, the cell phone battery inside all the "power" light, and then carefully for the first "charging ceremony", I heard that this will not hurt the cell phone battery, so that the phone can be a long, long time We serve. However, the recent purchase of mobile phones, friends say that this "cell phone with the photoelectric charge" is out of date?
Koko asked his friends and found that people disagree on this statement. So today, Keke Jun just talk to you in the end whether to use light cell phone battery, recharge?
Recharge with light, which is already veteran of the "nickel-cadmium batteries"
In the 1990s, the "nickel-cadmium batteries" assembled in cell phones made an unwritten rule in the "phone's manual" that the battery was drained after it was recharged, otherwise the capacity of the battery would drop .
In fact, this is because of the "memory effect" of nickel-cadmium batteries. Nickel-cadmium batteries have a characteristic, that is, in the discharge (cell phone use) process, if the battery power is not completely depleted, recharge the battery plate when there will be a lot of "small bubbles." In so doing, these bubbles reduce the reaction area of the battery plate and allow the battery's capacity to drop. Like a nickel-cadmium battery "remember" the shortened battery life, so that the charging cycle is also shortened, the battery capacity becomes smaller and smaller.
In addition, cadmium has some toxicity, is not conducive to environmental protection, so the basic nickel-cadmium batteries have been eliminated from the "digital equipment battery" circle.
Modern cell phone, want to charge to charge. This depends entirely on "lithium polymer battery."
Nowadays, most of the batteries we use on our mobile phones are "Lithium Polymer Batteries". The batteries can be fully charged and fully charged before they can be used for 2 ~ 3 hours.
Lithium-polymer battery is not like nickel-cadmium batteries have a "memory effect", its life is based on the "charge cycle" to decide. This battery is a reusable garbage bag, it can guarantee the rubbish 500 times, this bag is not damaged; more than 500 times, the garbage bag will be thinned, it can only hold the previous 80% More loaded hundreds of times, may only be installed before the 40% ~ 30%.
However, the "charging cycle" that determines the life of a cell phone battery now does not equal "number of charges." A charge cycle, means that we have to run out of all the electricity inside the battery. That is to say, if the phone had 70% of the charge the day before, it was fully charged. The next day it used 30% of the charge and was fully charged. We did not consume 2 charge cycles and only consumed 1 charge cycle.
Charging the phone one night, the battery is not good?
The phone has been charging, the impact on the battery is not large. After the phone is fully charged, the phone will also consume some of the standby power while the phone is on standby. In this case, the charger will use "micro-current" to compensate for the battery power loss, but this will not "overcharge" the battery. Once the voltage and current abnormal phenomenon, mobile phones and chargers will start the "protective measures", automatic power-off, to avoid accidents.
Too cold, too hot, the phone automatically shut down is how the case? Mobile phone battery "low temperature protection" function ...
I believe many people have encountered in the winter to take out a fully charged cell phone, the result was useless for 20 minutes, the battery declared no power off problem. In fact, this is the cell phone's "low temperature protection." When the weather is too cold, it is very difficult for the lithium ion to be embedded in the electrode, which will cause the lithium ion battery to be deposited (lithium metal is deposited). Therefore, the mobile phone will fall into the automatic shutdown state at this time to prevent the battery from being damaged. This time if the compulsory charging, it is likely to cause the battery short circuit, so in order to protect the battery, it is best to wait for the phone "warm" back to the temperature, then recharge it.

Why replacement mobile phone battery would spontaneously explode?
We might have heard many cased that lithium-ion replacement mobile phone battery burst into fire or even explode in the process of production, transportation and the usage process. There are three reasons:
1, From the structural point of view, it is related to the replacement mobile phone battery short circuit.
The short circuit of the replacement mobile phone battery will produce energy, which will lead to temperature changes and lead to the combustion and explosion of the organic solvents. When the battery is in a state of high temperature, or is subjected to impact or metal friction, it may cause the case of replacement battery short circuit and explosion.
2, The quality of the replacement mobile phone battery itself
Replacement mobile phone battery quality is related to the battery structure design, the composition of the replacement battery materials and phone battery production process. The current replacement mobile phone battery spontaneous combustion and explosion are mostly because of the use of mobile battery from illegal manufacturers. The use of unqualified product might lead to short circuit of the phone because of the excessive impurities in raw materials, unqualified manufacturing processes, and inaccurate design of the replacement battery safety protection.
3, Improper use of the user
In the case of long-term charge, the replacement mobile phone battery overcharge or too large current may lead to high temperature, laying a security risk. In special circumstances such as extreme temperature, high humidity and poor contact, lithium-ion batteries might get explode or spontaneous combuse because of too large instant current.
In fact, lithium batteries do not have to be charged until the replacement mobile phone battery is depleted. And it’s better to immediately unplug the charger when it’s fully charged. If charge when completely use up the lithium battery power, it will shorten the replacement battery life.
So how to properly charge the phone and prevent the replacement mobile phone battery from exploding?
(1) use high-quality replacement mobile phone battery
Most of the replacement mobile phone battery explosion is due to the use of poor quality batteries, so use the original factory or high-quality phone battery is most secure. Choose high quality batteries from reliable manufacturers, like Shenzhen Wanshuntong Science & Technology CO., Ltd. As phone battery manufacturer for over 17 years, high quanlity is visible.
(2) Check the replacement mobile phone battery at any time
If your cell phone batteries are replaceable, you should pay attention to whether there is any scratches on the phone battery or traces of impact on the cell phone. If so, it is better not to use it anymore.
(3) pay attention to charging safety
For mobile phones whose replacement mobile battery can not be replaced, such as iPhone, it is better not to charge after it gets wet, it is better to sent for repair to avoid a short circuit and explosion of the phone battery. Do not make phone call while charging and use the original charger if possible.

At present the metal shell on the market, all have the fireproof function, and the ABS and PC two kinds of plastic shell of the material is only part of the fireproof function, but most are not, so in the choice, you can consider the preferred metal shell power bank.
2, buy a full range of certified power bank
Here we mainly look at the products are obtained by the international and domestic quality certification, we all know that electronic products should have a formal certification, consumers can check whether the product has third-party certification or certification is complete, to obtain the confidence of the purchase . Third-party product certification to confirm the product is in line with certain quality standards and safety requirements. Where to buy power bank to pay special attention to the following four certification: UN38.3, 3C, MSDS and ROHS certification, as long as the four certification is generally reliable.
3, the capacity to see demand
In order to attract users, many manufacturers have introduced a large capacity mobile phone, and some even large capacity to 20000mAh. But you know? The capacity of power bank is proportional to the volume. In other words, high-capacity power bank supply, the volume will be larger, covering children, not portable.
If the phone is not very much power consumption, the road is not far away, one day to add electricity, then 5000mAh capacity power bank enough. However, if you are traveling abroad for long periods of time, you need enough power to run the car. You do not have to worry too much about moving the power too much. You usually have to go backpacking when traveling out and no place to put power bank. The specific choice to see everyone's own needs.
4, priority brand
The principle of the structure of the power bank is basically the same, so it will not be as difficult as the election mobile phone, which configuration is hesitant what they need. Mainly look at the appearance, capacity and price and security. The first three mainly depends on personal preferences, and security, is definitely the preferred brand, after all, as we all know, there is a certain risk of cottage products, and brand products more secure.
So even if you spend a little more money, choose to buy brand power bank, to add a more secure security, value for money.
5, formal channels to buy
Now the brand cottage products is too much like, for those who do not have the professional knowledge of identification, through formal channels to buy, you do not have to worry about pit friends. And through regular channels to buy power bank, manufacturers, all kinds of parameters, certificates, invoices, etc. is very complete, after-sales convenience.
6, shop around
To choose a more cost-effective, safer power bank, whether you are in the store or on the e-commerce platform to buy, shop around is inevitable. If not for a product has a persistent pursuit, you can compare more than a few brands to see more models, look at the same color, capacity, shape of the power bank, which brand more performance and safer. Such a reasonable price to buy the favorite product, but also equivalent to get a good mood.
In short, the purchase of power bank, sloppy sloppy, as the saying goes, you get what you pay for. The same token, for example, let you spend a million Traveling all over Europe and spend 10,000 to Travel to one country , which one would you choose?

Why do so many people rely heavily on cell phones, and even addiction?
Today, people's communication, travel, accommodation, work and entertainment are all inseparable from the cell phone, the small screen, hidden a fantastic world, so that people are deeply trapped in it, unable to extricate themselves.
When the mobile phone was first invented, the original intention of scientists was to break the barriers of space and to make it easier for people to communicate with each other. Now, however, people have become its slaves, more and more alienated from each other. All this should be a sobering phrase, science and technology is a double-edged sword.
▍ How much time do people spend on their cell phones every day?
take China as an example. In the early hours of June 1, 2017, Mary Meeker, a Wall Street securities analyst with the title of "Queen of the Internet," released the 2017 Internet Trend Report at the Code Conference in the United States. The report shows that in 2016 China's mobile Internet users in China exceeded 700 million (CNNIC data as of June 2017, the size of China's mobile Internet users reached 724 million). According to the China Institute of Information and Communication Research, shipments in China's handset market in 2017 were 490 million units, meaning that almost one in three Chinese changed their handsets last year. This shows that mobile phones have become very popular in China and have become indispensable products for most people's lives.
The report also shows that in 2016, China's mobile users daily online length of more than 2.5 billion hours, converted, the average daily spending on mobile phones more than three hours. And in 2017, as mobile games heat up, the amount of time people stare at the screen every day increases only.
▍ What are you playing on your cellphone every day?
Empress's report also shows that the most frequently used Chinese daily applications are WeChat, QQ, YOUTOBE, browsers and Weibo. Chinese users spend 3.1 billion hours a day on mobile applications, while Optical WeChat accounts for 900 million hours.
See these data, people can not help but emerge in my head such a picture: three or four o'clock in the morning is still still aimlessly brushing micro channel, and sometimes awakened could not help turning over to open the phone to continue brushing, the next morning Wake up is to open the phone to see if anyone is looking for, late night circle of friends and updated what ... ...
Such as the red light, the subway, eating, chatting and even when the couple intimacy ... ... almost every moment we have a moment can not help but want to open the phone, even if you do not do anything, just lit the screen, paddling a few , Then turn off the screen. Some people even feel the cell phone power shortage uncomfortable, do not play cell phones one day like to have their own lives.
▍ Why do people bored with cell phones everyday?
Mobile phones not only consume a lot of our daily routine, but also deeply affect our contact with other people: family together, not to talk happily, but to watch their own computers and mobile phones; friends gatherings, not gossip year, but desperate In the brush weibo and friends circle; class time, the teacher in the podium punchline, the students are playing games under the watch video; meeting, the boss said the annual plan, the people are busy back to the mail, send messages ...
Known by Kevin Kelly as "Floyd" in technology, Sherry Turkle, a leading social psychologist in human-technology relations, attributes these phenomena to "group solitude" We seem to be together, but actually live in their own "bubbles." We look forward to fewer others and look forward to more technology. Uninterrupted contact, whether to make mankind caught in a deeper loneliness?
In February 2012, Shirley Turkel once again boarded the TED's Podium, giving us a speech that profoundly explores the relationship between people and science and technology: "Always keep in touch, but still feel lonely (Connected, but alone? ) ". Shirley Turkel, in her speech, summed up the three big misconceptions that make people obsessed with cell phones or other electronic products: First, we can allocate energy to whatever we want to focus on. Second, someone will always listen to us. Third, We will never be alone.
We can allocate energy to whatever we want to focus on
We used to think it was a curious or annoying thing to do when we were in class and having a cell phone while eating. People are always hoping to stay with each other and at the same time "elsewhere" - connect to wherever they want to go, and people are used to being "so alone" because the most important thing for them is controlling And distribute their energy.
As one netizen JZeng said, we rely not on cell phones, but on the entire world connected by cell phones. Technology keeps us connected to the world anytime, anywhere, just as we breathe air. That tempting world is obviously more attractive than the people and things around them - until they are lost.
Someone will always listen to us
"No one can get enough attention from each other, no matter what generation." We have countless automatically generated "listeners" in weibo and friends circles, and the feeling that no one is willing to listen makes us More willing to stay with our machines that seem to care about us.
Perhaps many hope that one day, a newer version of Siri, the Apple Voice Assistant for iPhone, will be more like a good friend, a close friend who listens patiently when no one else pays attention to you.
We will never be alone
People come to this world nakedly, and go naked, the vast twists and turns of the mind, the brain a thousand turns, who really understand? Loneliness is an irresolvable and eternal proposition of mankind.
Why do not you talk face to face?
Shirley Turkel had asked why people did not talk face to face? Someone replied: Because face-to-face conversations happen in real time, you can not control what you're saying. Yes, through the smart phone, we in the circle of friends, microblogging to present themselves are edited, modified, retouched and deleted to achieve what we want to become like. You will be in a panic once face-to-face, you will not say anything, and you will make minor mistakes so that we are not perfect in the eyes of others.
But can these tiny, brief, live, online episodes be combined with true conversations? "No, the exchange of this small snippets of information may collect well-groomed information, but it's hard to get us to know each other and really understand and understand each other."
▍ addicted to cell phone what harm? Duopus actually destroyed the earth
The advent of cellphones has brought countless conveniences to us, but it has also allowed the warmth of this world to fade away. Immersed in social software every day, with a little praise to maintain the feelings of crumbling, one after another laughing behind the expression package you, really happy?
▍ conclusion
Along the way, cell phones are just a small tool obsessed with the long history of mankind. We have also been obsessed with television, computers, we will obsessed with the future, no one in the heart of the spectrum. Neil Postman, the critic who worries in his classic 1985 book Entertainment to Death, never dies: human beings are vassals of entertainment, complacent, and even willing, The result is that we have become a fun-to-death species.
Every day we constantly brush, send friends circle, so that those who did not matter occupy all of life. "I share, so I exist"? No, just let go of the phone and you will understand "Sometimes you want to prove it to 10,000 people, but in the end you discover that only one person understands that's enough."
We are not saying that we should completely abandon the mobile phone, abandon all the indulging electronic products, and return to the era of "old slow". "I just suggested that we should build more self-aware relationships with electronic devices and with others and ourselves," says Shirley Turkel.

Detailed rechargeable lithium batteries in power bank
With the prevalence of large-screen smart phones, their own battery technology bottlenecks, more and less mobile phone standby time more than a day. This gave birth to a new product category - power bank
As the technology advances, 5000 mAh power bank is still the starting number. 8000,10000,15000 or even 20000 mA power bank abound. The current charge Po market is very chaotic, from tens of dollars to several hundred dollars, a variety of blind brands Akira blind eyes (a top domestic providers on the category of rechargeable treasure there are hundreds of brands). However, there are still many charging Po door inside. For example, its appearance, round, flat, long, square, flaky and even plush toys! There are also its standard differences, such as talking about the airport when the wind, rather than what we commonly call the milliampere. More and more functions, such as storage, wireless routing, card reader function and so on.
Discharge efficiency is the most important cell, it is how the same thing?
The current charge Bao batteries generally divided into 18650 batteries and polymer lithium-ion batteries.
Their appearance is also very good.Cylindrical, relatively heavy charge treasure are generally 18650 batteries.
Polymer lithium-ion batteries size, appearance can be customized design. For example, some very thin, weird appearance, tablet power bank.
Now there is a saying, 18650 batteries lower than the polymer lithium-ion batteries, always feel put a few rechargeable batteries in it. Is this true?
Of course not!
WST which is 18650 batteries, do you think it will be worse thing? Battery points A, B, C level, if all A-level batteries, the same milliampere batteries discharge efficiency is almost the same. This argument is mainly to sell polymer lithium-ion batteries, high-priced vendors used to attack opponents marketing strategy. Everyone wants to know this.
So the so-called kind of batteries better myth does not exist. It is important that the battery level, to identify the maker brand, to ensure that the battery level.
Nominal 5000 mAh will be able to charge 5000 mA Well?
Not necessarily!
This is related to its charge-discharge efficiency.
Most of the power to close to 76% of the conversion efficiency is already good. For example, 10000 mA can charge 7600 mA to your phone, it is a very good conversion efficiency.

Mobile phone battery power and then recharge the battery better?
Each time you buy a new cell phone, the cell phone battery inside all the "power" light, and then carefully for the first "charging ceremony", I heard that this will not hurt the cell phone battery, so that the phone can be a long, long time We serve. However, the recent purchase of mobile phones, friends say that this "cell phone with the photoelectric charge" is out of date?
Koko asked his friends and found that people disagree on this statement. So today, Keke Jun just talk to you in the end whether to use light cell phone battery, recharge?
Recharge with light, which is already veteran of the "nickel-cadmium batteries"
In the 1990s, the "nickel-cadmium batteries" assembled in cell phones made an unwritten rule in the "phone's manual" that the battery was drained after it was recharged, otherwise the capacity of the battery would drop .
In fact, this is because of the "memory effect" of nickel-cadmium batteries. Nickel-cadmium batteries have a characteristic, that is, in the discharge (cell phone use) process, if the battery power is not completely depleted, recharge the battery plate when there will be a lot of "small bubbles." In so doing, these bubbles reduce the reaction area of the battery plate and allow the battery's capacity to drop. Like a nickel-cadmium battery "remember" the shortened battery life, so that the charging cycle is also shortened, the battery capacity becomes smaller and smaller.
In addition, cadmium has some toxicity, is not conducive to environmental protection, so the basic nickel-cadmium batteries have been eliminated from the "digital equipment battery" circle.
Modern cell phone, want to charge to charge. This depends entirely on "lithium polymer battery."
Nowadays, most of the batteries we use on our mobile phones are "Lithium Polymer Batteries". The batteries can be fully charged and fully charged before they can be used for 2 ~ 3 hours.
Lithium-polymer battery is not like nickel-cadmium batteries have a "memory effect", its life is based on the "charge cycle" to decide. This battery is a reusable garbage bag, it can guarantee the rubbish 500 times, this bag is not damaged; more than 500 times, the garbage bag will be thinned, it can only hold the previous 80% More loaded hundreds of times, may only be installed before the 40% ~ 30%.
However, the "charging cycle" that determines the life of a cell phone battery now does not equal "number of charges." A charge cycle, means that we have to run out of all the electricity inside the battery. That is to say, if the phone had 70% of the charge the day before, it was fully charged. The next day it used 30% of the charge and was fully charged. We did not consume 2 charge cycles and only consumed 1 charge cycle.
Charging the phone one night, the battery is not good?
The phone has been charging, the impact on the battery is not large. After the phone is fully charged, the phone will also consume some of the standby power while the phone is on standby. In this case, the charger will use "micro-current" to compensate for the battery power loss, but this will not "overcharge" the battery. Once the voltage and current abnormal phenomenon, mobile phones and chargers will start the "protective measures", automatic power-off, to avoid accidents.
Too cold, too hot, the phone automatically shut down is how the case? Mobile phone battery "low temperature protection" function ...
I believe many people have encountered in the winter to take out a fully charged cell phone, the result was useless for 20 minutes, the battery declared no power off problem. In fact, this is the cell phone's "low temperature protection." When the weather is too cold, it is very difficult for the lithium ion to be embedded in the electrode, which will cause the lithium ion battery to be deposited (lithium metal is deposited). Therefore, the mobile phone will fall into the automatic shutdown state at this time to prevent the battery from being damaged. This time if the compulsory charging, it is likely to cause the battery short circuit, so in order to protect the battery, it is best to wait for the phone "warm" back to the temperature, then recharge it.

Rich lithium-manganese-based battery: the future development of lithium mainstream direction?
Compared to the current industry-leading high-nickel ternary batteries and all-solid-state lithium batteries, high hopes of lithium-rich manganese-based batteries have been slowing down.
From the current technology point of view, by reducing the mass ratio of batteries in the non-active mass to improve the energy density of the battery has reached almost the technical limit, the use of positive and negative materials with higher energy density is to improve the battery energy density more As a valid technical way.
We know that the first criterion for the design of the battery is to match the capacity, that is, the capacity of the positive and negative to match. At present, lithium-ion battery cathode capacity is very low, the quality of the battery is very large (1g graphite anode material to match more than 2 grams of cathode material); with silicon carbon anode, the cathode material more matching. Therefore, the industry's demand for a new generation of high-capacity cathode materials is particularly urgent.
Among the known cathode materials, the lithium-rich manganese-based cathode material discharge capacity of 250 mAh / g or more, is almost twice the actual capacity of commercial cathode materials at the same time this material is cheaper manganese Mainly low precious metal content, compared with the commonly used lithium cobalt oxide and nickel cobalt manganese ternary system cathode material, not only low cost, but also good safety. Therefore, the lithium-rich manganese-based cathode material is considered as the ideal choice for the next generation of lithium-ion batteries and is the key technology for lithium batteries to break through 400Wh / kg and even 500Wh / kg.
Although the lithium-rich manganese-based positive electrode material has the absolute advantage of specific discharge capacity, it is necessary to solve the following key technical problems in practical application of lithium-ion battery: First, to reduce the first irreversible capacity loss; second, to improve the rate performance and cycle Life; third is to suppress the voltage decay cycle. At present, there are many ways to solve this material problem: coating, acid treatment, doping, pre-circulation and heat treatment. However, these methods can only improve the performance of materials in some aspects and there is no perfect solution. Therefore, some people in the industry even predicted that it is not realistic to realize the industrialized application of lithium-rich manganese-based power battery.
As you can see, the outlook is good, but there is still a long way to go before the lithium-rich manganese-based power battery can be used.
Wanshuntong mobile battery believe that from the cathode material development direction, the lithium-rich manganese-based material has both high voltage and high capacity advantages, and the cost is lower than the ternary material, with the future maturity of lithium-rich manganese-based cathode materials, and high voltage electrolyte Such as supporting the breakthrough of key materials technology, lithium-rich manganese-based battery into the future than the mainstream of high-energy lithium battery.

The causes and repair methods of Power bank battery loss energy
Power bank lithium-ion battery has a design capacity, the data can be seen on the battery label, some in "mAh" said, such as "4400mAh", while others are "watt-hour" Said, such as "23Wh." This capacity value is the theoretical maximum battery capacity. With the use of the battery, the actual maximum capacity will be gradually reduced, while the reduction of this part of the capacity is the battery loss. Such as Power bank battery theoretical capacity is 4400mAh, after using for some time, the actual maximum capacity has now become 4200mAh, then the battery loss is (4400-4200) /4400*100%=4.5%. Below with the power management Xiaobian together to understand the relevant content.
Battery loss refers to the battery after a long time, the actual capacity becomes smaller, lower than the nominal capacity. Battery loss is commonly known as memory effect, but generally refers only to the memory effect of the Power bank computer.
Power bank Battery loss reasons
1, the battery itself is of poor quality
2, the use of low-quality charger
3, high temperature or low temperature environment for a long time
4, the use of batteries is connected to high-load peripherals, plug and unplug.
5, over charge and discharge (the battery to the remaining capacity of less than 3%). Circuits are protected, but occasionally happen.
6, not fully charge and discharge (did not run out and then recharge, but want to use it, want to charge on the charge)
7, the long-term use of electromagnetic radiation in the battery (will interfere with the battery conductivity of the metal)
8, long-term use of the battery in wet conditions (humid batteries will reduce the performance)
Power bank battery loss energy ,repair method
1, we can directly discharge the Power bank battery, and then reinstall it so that we can repair the Power bank battery, but the degree of repair is partial, can not be completed repair. First unplug the Power bank, stop charging, and then run out of the remaining power of the Power bank computer until it can not be turned on, and then connected to the power charging, so repeatedly charge 2 times or so, and then test Power bank battery loss level, we found that the degree of loss reduced.
2, of course, you can also Power Bank refresh program to restore the discharge time of the Power bank battery repair Power bank loss. Power bank's refresh program can be downloaded through the official website of the Power bank brand, and then press and hold F8 to enter the DOS system to perform battery refresh procedure. Refresh program execution is also done to the Power Bank loss played a certain role in the repair.
3, a lot of lithium battery failure is caused by the failure of a battery pack in the battery pack, this phenomenon can not be avoided. Because of the nature of batteries per cell can not be exactly the same, with some of the quality of a little after a long time began to deteriorate, and undermine the whole (after the series) of the discharge curve. Interested and capable readers can try to open the battery pack, with the help of the multimeter can quickly find the damaged batteries (voltage anomalies). If the conditions permit, according to the exchange of qualified batteries can correspond to the parameters.
The above is about power management -Power bank battery loss reasons and repair methods related to the introduction, if you want to know more about the information, please pay attention to powerbankmobilebattery.com, we will provide you with more complete, more detailed and updated information .
