1 Find the reason for power consumption. Enter the main interface, settings → other advanced settings → power supply and performance → power consumption. Here, we can find out the power consumption ratio of software and hardware, the power consumption order of software and the power consumption order of hardware. There are three main aspects of power consumption in real life: ① power consumption by running software in the background, ② power consumption by screen, wi-fi and Bluetooth, and ③ power consumption by system upgrade.

2 Close and delete power-consuming software. Enter the main interface, press the menu key, and empty the running software. Press and hold the menu button to clean up the software that is not commonly used.

3 Develop the habit of closing the screen. As can be seen from the arrangement of hardware power consumption, the power consumption of the screen is large. Therefore, we should get into the habit of turning off the screen after using the mobile phone.

4 Turn off wi-fi and Bluetooth properly. In some cases, such as airplanes, subways and highways, there is no wi-fi signal, so you can turn it off to save electricity. Turn it off when Bluetooth is used up, which saves electricity and ensures information security. In addition, turning off these two items will also reduce the radiation received by the body.

5 update MIUI system. In fact, the real power consumption is the update of MIUI system. I remember one time, I never updated the Android system, and I ran out of electricity in one day. By default, the system will automatically download the updated MIUI system in the case of wi-fi, waiting for the user to manually press the system update (the mobile phone needs to be restarted). But sometimes when users are busy using their mobile phones, this process stays in the background without updating the system, which consumes a lot of power. As long as it is updated, the power consumption speed will drop.

6 Turn off the automatic update of MIUI. Update the system frequently, and you will feel as if you have been kidnapped. You can't always be a mouse. Just turn off system update: App Store → My → Settings, and turn off automatic upgrade and silent installation. Do the above six steps, will you have a strong battery life like me?
