Moreover, Apple's mobile phone has a common problem, that is, when the battery has a certain loss, the processor will reduce the frequency. Because Apple's processor has high performance, it also requires high battery voltage. If the voltage is insufficient, it may cause the phone to shut down and restart unexpectedly. When the battery has a certain loss, the voltage will gradually drop. At this time, in order to ensure that the iOS system will not be shut down unexpectedly, it will reduce the running frequency of the mobile phone processor, resulting in the system being stuck.
If the battery reaches 8 1%, there will be obvious battery life decline, and of course the battery can be replaced. After all, the efficiency of 8 1% is not high, so it is no problem to replace it. After all, the battery belongs to the wear and tear of the mobile phone, so don't care too much, and it doesn't cost much to change the battery now. If you care about these values, you can completely replace them with a new one.
