note! Apple released a tutorial: high temperature charging permanently damages the battery

As we all know, mobile phone batteries will age with the degree of use, and the battery capacity will decline accordingly, becoming less and less durable.

Recently, Apple's official website has given some suggestions for extending battery use time and life, as well as the temperature environment suitable for charging Apple devices.

The first is to keep the battery away from extreme temperatures, the ideal temperature range for the operation of the device is between 16 ° C and 22 ° C, and the most important thing is to avoid being in a place where the ambient temperature is higher than 35 ° C, otherwise the battery capacity may be permanently damaged.

Not only charging, but even storing the battery in a high temperature environment can cause irreparable damage.

But interestingly, although the temperature is too low, although the battery life is reduced, it is only temporary, and when the battery temperature returns to normal temperature, the performance will return to normal.

Apple suggests that when the device is charged together in some styles of protective case, it may generate too much heat, which will affect the battery capacity. If you notice that your device is getting hot while charging, remove the case first.
