Correct charging and usage of cell phone batteries

1. Lithium battery, whether in use or not, has a "shelf life" of 3 years and will decay rapidly after 3 years. As for the full charge cycle, which I'm not going to explain anymore, it is going to decay really fast after about 400-500 cycles. It depends on whether you use it for 3 years or charge it first.

2. In addition to low power, lithium battery is also afraid of overheating, especially when charging. If you have a bad case of heat dissipation and you get hot while charging, it's best to remove the case while charging. The long-term storage method of lithium battery is to charge to 40% and put in the refrigerator, but remember not to freeze.

Don't wait until the power runs out before charging it, it will speed up its loss. Lithium batteries wear out a lot when they're low, and they last the longest when they're at 40 to 60 percent, but for devices that you use a lot, that's not possible, but you can keep them at 100 percent, which is to charge them often and never pull them out. It won't overcharge, and since it's powered by a mains battery, the battery won't waste charge cycle, so it helps prolong its life. You only need to fill it up once a month to calibrate the battery gauge. 4. It can be used during charging. Some people say that charging will lead to slow charging. Actually, there are two circuits in the phone, one is to charge the battery, and the other is to power the machine directly through AC. Charging is slow because part of the current is used by the machine, so the charging current is small, especially in usb charging, because the current itself is small. However, it is worth noting that low current and slow charging is the preferred charging method for lithium batteries, which generates less heat and is more conducive to its life. Also, don't play games or other heavy loads while charging! The reason is not the high power consumption, but the high heat generated by the same 2, thus reducing the battery life. Go up commonly get online, hair message is no problem, hold in the hand for a long time make a phone call also bad, the proposal USES earphone.

5. It will not cause any harm to the battery if it is connected to the power supply after charging, because it is directly powered by the power supply, which reduces the charging times and is beneficial to extend the battery life. A lot of people would argue that my laptop was plugged in all the time, and the battery died a year later. Unlike a mobile phone, which is often caused by heat, a laptop with poor heat dissipation can lose battery life quickly, even if you don't use it. If you always play games on the power supply, your phone may overheat due to the high heat generated by the power supply, which is not good. As long as you don't overheat, there will be no problem. Personally, I think safety is the most important thing and someone should take care of it. 6. (to be discussed) it's also not good to always connect to a power source when the battery is above 90% but below 100%, always "topping off." ThinkPad laptops have a mechanism to keep their batteries uncharged for more than 90 per cent of the time. If only the phone had a charging switch, we could safely use external power for a long time. It is no problem for the battery to be charged continuously at 20%-80%.

Charging overnight doesn't hurt at all because you're not using it and it doesn't generate heat. The individual thinks overcharge, from beginning to end is not what good matter, had better not charge at night, voltage is not steady when partial area night, harmful to the machine!!

Generally speaking, the new charging time is about 4-6 hours from 0% to 100%; Try to fill it up after the first use. The phone itself USES a lithium-polymer battery that lasts about 10 hours. It takes about four hours to charge from 10% to 100%.

The first three charges do not need to be charged for a long time, just 5 or 6 hours, the polymer battery performance is higher than any battery, plus the charger itself with overcharge protection, so it can be filled. However, one thing to keep in mind is not to wait for the battery to run out of power before charging, which will affect the battery life.

It is recommended to charge the battery when there is about 15% of the battery. If you catch up with the night when the charge, do not deliberately pull up the power supply, charge a night is just as well.

"There's a lot of talk about the 'activation' problem with a new lithium-ion battery: it has to take more than 12 hours to recharge, and you have to do it three times to activate the battery. This "the first three charge to charge more than 12 hours", obviously from the nickel battery (such as nickel cadmium and nickel hydrogen) continued to say. So this kind of saying, can say to be misrepresented namely at the beginning. The charge-discharge characteristics of lithium battery and nickel battery are very different, and it can be very clear to tell you that all serious formal technical data emphasize that overcharge and over discharge will cause great harm to lithium battery, especially liquid lithium ion battery. Therefore, it is best to charge according to the standard time and standard method, especially do not charge more than 12 hours. So does the battery need to be activated? The answer is yes, it needs to be activated! However, this process is done by the manufacturer, not by the user, and the user is not capable of doing it. Real activation process is as follows: lithium-ion batteries, lithium ion battery shell infusion electrolyte - seal - into, is the constant voltage charge, and then discharge, so for several cycles, the electrode fully infiltrates electrolyte activates, until capacity requirements, this is the activation process, capacity, that is to say the factory after the lithium ion battery to user hand is already activated. In addition, the activation process of some of the batteries requires the battery to be in the open state, and then seal after the activation. Unless you have the cell production equipment, how to complete? But why do some product manuals say that users are advised to use the first three times, to charge and discharge the phone completely? Isn't that activation? In fact, the fact is that when the battery is delivered from the factory and sold to the user, it will experience a period of time, a month or several months. As a result, the electrode material of the battery will be "passivated", and the capacity will be lower than the normal value, and the service time will be shortened accordingly. But lithium battery is easy to activate, as long as after 3-5 normal charge and discharge cycle can activate the battery, restore the normal capacity. Due to the characteristics of lithium battery itself, it has almost no memory effect. Therefore, new lithium battery users in the activation process, is not required special methods and equipment.

In fact, the smart mobile phone use is lithium battery, it is not you imagine so fragile, when cell phone batteries, charging power supply is cut off automatically, to avoid overloading the overcharge, so don't worry about the battery damage, also need not up and pulled out the power supply in the middle of the night, the user can set his mind at to sleep a good sleep!

Of course, it should be noted here that the use of mobile phone charger must be a regular charger, preferably the original charger. Some copycat or model mismatch charger, it is best not to be used to charge the phone at night, to prevent poor quality chargers, chargers burn, injury to the phone.

New phones just bought back, many people will be used to the phone power all used up, until automatically shut down, and then recharged, or even so to use three times before rest assured.

In fact, there is no need to do so, now the mobile phone battery is lithium battery, before the factory has been activated, do not want to be like the previous battery through a thorough charge and discharge to activate the battery.

Now using the old method, it seems superfluous, not only can not help, and even damage the battery.

Usually when using mobile phone, it is necessary to use the power of the mobile phone to automatically warn the lack of power before charging, they feel that in the case of enough power to charge the mobile phone, is to reduce the number of mobile phone battery charge and discharge, shorten the service life of the mobile phone battery.

In fact, the current mobile phone is lithium battery, pay attention to is "eat more meals less", more can play a role of lithium battery.

? Some people think that mobile phone charging should not call or play mobile phone, for fear of explosion.

May usually see the news more, in fact, the current mobile phone lithium battery has a self-protection function, is when the battery short circuit or excessive discharge, will automatically cut off the power supply, basically no explosion accident.

? And the explosion is generally caused by the use of mismatched or non-original batteries, or the use of unqualified batteries, which are very low probability events, as long as the normal operation, do not need to worry about the occurrence of these explosion accidents.

Generally speaking, when the mobile phone is charging, if the fever will be more severe, then do not call or play games, or something unexpected will happen, that is too sad.

Use the original charger?

Almost everyone in the family will have a mobile phone, the mobile phone is out of power, just pick up a charging head to start charging the mobile phone. Wrong, the best way to charge a mobile phone is to use the original charger.

? Because the amperes and volts of mobile phone charging are different now, the power used by standard charge and quick charge is also different. If a high-power charging head is used to charge a low-power mobile phone, the charging speed will be accelerated, but it will cause potential safety hazard to the mobile phone battery. Small power to power mobile phone charging will be too slow, so it is best to choose the original charging head.

Many iPhone users have a habit of using the same charger for both iPad and mobile phone, but you will find that if you use the phone charger to charge the iPad, it will be very slow, but if you use the iPad charger to charge the iPhone, it will be very fast. This is because the power of the iPad charger is greater than that of the iPhone, which will have a great impact on the phone battery, so the charger must be the original.
