The quality of batteries on the market now is not worse than that of Apple's original ones, and their capacity is also larger than that of the original ones, which means that their battery life will be longer. But choose the kind that is guaranteed by big brands. Of course, if you pay more attention to the warranty, you should try to replace the battery at the official level. The pool will always be worn out. When the battery capacity can't meet your needs, change the battery or mobile phone!
Here we should focus on the performance management module of iOS: generally, a normal Apple phone will not start, and when your Apple phone is turned off unexpectedly for the first time, performance management will automatically start. Mobile phones automatically manage performance peaks, such as frequency reduction, to prevent accidental shutdown. Under normal circumstances, the battery life of a mobile phone is used up, which means that you should change to a new generation of mobile phones. So don't worry about it.
It is inevitable that the battery capacity will decrease, but there is a saying that it is necessary to reduce the speed and take preventive measures to make the battery last longer. Don't wait for the battery to run out before recharging. Mobile phone batteries should be charged at 10%-20%. Don't use your mobile phone a lot when charging, such as playing games and brushing videos. Don't put your mobile phone in extreme temperature. When charging between16 c-22 c, it is best to take off the phone case and use the original charger.
