Does fast charging damage the battery? He has done a comparative test for everyone. Let’s see the results~~ [Copy link]

It is said online that fast charging is harmful to the battery, and charging with too low or too high a charge is bad for the battery. Do you think this makes sense? How can we better protect the battery and make it more durable?

He has given us more comparative tests. Let’s take a look at the results.

Regarding Mr. He’s test results, why is it like this? Can anyone who knows analyze it? ? ?

Does fast charging damage the battery? Strictly speaking, it is indeed more harmful to the battery than slow charging, but the disadvantage is so small that it can be completely ignored. If you need fast charging, just go for it. This topic has been discussed many times on this site.

The materials are different. You can only injure a little bit, not too much.

Actually, I have a question, how do you view the battery health index? What indicators are used to evaluate it?

The battery health index is the ratio of the current maximum available capacity to the factory rated capacity.

This depends largely on the battery level software algorithm

There are two commonly used mobile phones.

Nowadays, mobile phone batteries have large capacity and charging current is larger, usually greater than 1C, which will definitely affect the battery life.

For example, Xiaomi's 120w fast charge can fully charge a phone in 9 minutes. The battery life of the phone will definitely not be long.
