How much charge current is best for iphone's battery

1. In daily use, it is better for apple phones not to use automatic shutdown, but to charge the phone when 20-40% of the phone's power is used, which can be removed when full.

2.Early cell phones used nickel-cadmium and nickel-metal hydride batteries, which required similar "activation."

These batteries will produce a "memory effect", charging in the state of incomplete discharge, easy to make the battery overcharge, time for a long time will let the user feel that the power will soon run out, so the first time needs to be full of 12 hours, and each time it is best to use up the power to recharge.

3.The battery used in iphone is lithium ion battery. Its initialization process is completed at manufacturing time, so activation is not required when it is first used. Lithium battery also has no memory effect and can be charged at any time. If the mobile phone is automatically turned off, the lithium battery will lead to low internal voltage due to excessive discharge, and it may be unable to start up and charge. Accordingly, lithium battery is charged pay attention to "eat less much meal", frequent shallow charge discharge is helpful for prolonging its life more.
