Is the battery healthy and accurate after Apple replaced it?

First: No matter what kind of mobile phone battery, it has a self-cycle life. When life ends, it must be replaced. Generally speaking, mobile phones that have been used for a long time are the "battery components" that are most prone to problems and are sent for maintenance.

Second, official website explained that the battery of iPhone only charges and discharges about 500 times. In other words, every time the mobile phone is charged 100%, it will cause loss to the components of the battery itself. According to living habits, it is impossible to charge and discharge at 100% to 0% every time, so 500 times is the limit. At this limit, the mobile phone battery should be replaced.

Third: If you want to know the battery life of your iPhone, that is to say, how long it will take to reach the limit of 500 times, we can use App software for auxiliary calculation and recommend a free APP called battery life, which can be easily understood by downloading and opening it.

Fourth: Apple suggested that the iPhone cycle more than 500 times, and the battery charging capacity is 80% of the original. At this time, you can find the original factory for maintenance. If you have passed the one-year warranty period and have not purchased Apple Care, the user must bear the cost of replacing the battery. According to the maintenance cost provided by Apple official website, the battery maintenance cost of all iPhone models exceeds the warranty, which is 2590 yuan.
