Have you found that after the battery of your mobile phone is less than 20%, the battery disappears very quickly, almost at a speed visible to the naked eye?

But when it falls to 1%, it is very durable, and it can hold on for a long time even by making phone calls and sending messages, which makes people feel that there is a divine force supporting it. This is not the mobile phone battery problem, but the mobile phone battery management system is playing a role.

So how does the mobile phone battery management system work?

Battery management system set up to protect mobile phone battery

If you say that your mobile phone consumes electricity very quickly only when it is less than 20%, there is basically nothing wrong with it.

We all know that excessive discharge of the mobile phone battery is bad for the mobile phone battery, and the mobile phone will remind users that the battery is too low as soon as it reaches 20%. All these are to protect the mobile phone battery. The battery management system for mobile phones is also set up for the same purpose.

When the amount of electricity is less than 20%, the ratio between the voltage and the amount of electricity of the mobile phone changes, and it is not so accurate to estimate the amount of electricity according to the voltage.

In this inaccurate case, for the purpose of protecting the batteryThe power management system will limit the amount of electricity as much as possible to remind users to charge as soon as possible. So less than 20% is not really fast power-off, but the displayed value is incorrect.

But if the power is cut off very quickly at more than 20%, two or even three charges a day, it could be for the following two reasons.

1. Android machine runs too much in the background.

If it is an Android phone, it is recommended to reduce the number of applications running in the background. A friend told me that her cell phone lost power quickly, and the battery of her phone had just been changed. Let me see why.

If it is an Android phone, it is recommended to reduce the number of applications running in the background. A friend told me that her cell phone lost power quickly, and the battery of her phone had just been changed. Let me see why.

Later, I took a look around, in addition to the fact that she used her mobile phone for a long time every day, but also because she opened too many background programs, all the running programs were not turned off, and the phone was turned off every time.

two.. If the battery is used for too long, the battery will age.

If you use it for too long, it is inevitable that the mobile phone battery will age for about 3 years. If you like to charge your mobile phone with video games, the battery of the phone will age faster.

The hot mobile phone consumes a lot of mobile phone components. If you want to use your mobile phone battery for more time, it is recommended not to play with your mobile phone while charging.

If the battery is really aging, you can go to the offline store to replace it, and now the battery service is also very convenient, which can be done at about 100 yuan. If the mobile phone continues to fly for a long time, the feeling of using it will be improved.
