For example, it needs to be recharged twice a day. It is recommended to change the battery. I suggest you go to the official after-sales or Apple Direct Store to replace it. There is a three-month battery warranty service after battery replacement, which is professional and guaranteed.
Extended data:
Even if the third-party non-iphone original battery is replaced, it is not that the mobile phone cannot be used normally, but some battery functions cannot be displayed.
Some will display the word "maintenance" in the column of battery health, instead of the battery efficiency percentage of iphone, so that we can't judge the usage of mobile phone and the battery utilization rate by the battery of mobile phone, and then we don't know when to replace the battery.
Apple has introduced the function of changing batteries, which actually makes many people still think that the original batteries are reliable, so they will use the original batteries instead of choosing cheap unqualified batteries, thus reducing the occurrence of safety accidents.
