Apple batteries cannot be replaced.
Take the iPhone 13 Pro as an example. During the use of the phone, the battery will gradually decay and the health will decrease. This is an irreversible normal phenomenon and its health cannot be improved through scientific methods. If you feel that the battery is healthy It has a relatively low impact on use. The only way is to replace the battery. The new battery will show 100% battery health and will slowly decline over time.

It can convert chemical energy into Electrical energy device. It has positive and negative poles. With the advancement of technology, batteries generally refer to small devices that can generate electricity. Such as solar cells. The performance parameters of the battery mainly include electromotive force, capacity, specific energy and resistance.
Using the battery as an energy source, you can obtain a current with stable voltage, stable current, stable power supply for a long time, and little influence from the outside world. Moreover, the battery structure is simple, easy to carry, and the charging and discharging operations are simple and easy. It is not affected by external climate and temperature, has stable and reliable performance, and plays a great role in all aspects of modern social life.
