With my many years of experience and experiments to tell you, the current lithium battery is afraid of three situations.
1. Overcharge.
2. Overplay.
3. Temperature. To explain: 1, overcharge is full of not unplug the charger or full of unplug and plug in, in order to charge more full (obsessive-compulsive patients will do so), although the current mobile phone and charger are protected, full will automatically break, not to charge bad, but the above two situations will still affect the battery life. And not unplugging the charger will discharge and recharge. 2, the consequences of overdischarge are more serious, excessive discharge will have irreversible damage to the current lithium battery, the capacity will be significantly reduced, the specific performance is always used, the use of automatic shutdown, although the mobile phone will retain some power, as above, the same will have an impact, many times after the use of the mobile phone automatic shutdown, standby time is significantly reduced. 3, the temperature, specifically, the temperature is too high or too low will affect the battery life. Needless to say, we all know that the battery is a chemical discharge, the chemical reaction must be affected by the temperature, the temperature is too low the reaction will slow down, resulting in reduced discharge performance, which is why the iPhone will automatically shut down in winter when the temperature is low, which is a protective mechanism, because the discharge performance of the low temperature battery is not enough to provide the power of the motherboard chip. It will damage the chip, so the iPhone will automatically shut down when the temperature is low to protect the phone, which is not a problem with the phone, but the temperature threshold may be set a little high, and it will feel that the temperature is slightly lower and it will shut down, which is very delicate, and this is also related to battery loss. Of course, the same way that the temperature is too high, it will not be explained in detail, the truth is similar, when charging the temperature is too high or too low, it will prompt the temperature to normal and then charge, these other mobile phones do not know whether there is, the iPhone is some. In summary, that is, try not to use the battery too low, avoid excessive discharge, do not fill the charger or charge repeatedly when the battery is full, avoid overcharging, do not store, use and charge the battery at extreme temperatures. The specific and simple explanation is that if the overcharge temperature is appropriate, it is absolutely no problem. Say more, how to say the battery, how to protect, after all, it is a consumable, the use of performance decline, feel that the standby time is significantly shorter, directly replace it, than usual a variety of protection will save more things, I am now like this, the new mobile phone do not care, how to use it. (Pure mobile phone code word, so tired......)
