Displaying the battery health percentage via the settings is generally not available on other Android phones, with the exception of HUAWEI, but it is quite easy to find out the battery level.

How to Check Xiaomi Battery Health using ADB/LADB

With this method, it is not necessary to use a computer to check the battery capacity. You can easily find out the battery capacity and battery health percentage with LADB on your phone. If you want to do it with a computer, you should first install the ADB drivers from this article. After that, you need to enable developer options on your phone and turn on USB debugging. There is one more detail you should not forget: Your phone must be 100% charged. If you perform operations without fully charging your phone, you may measure the battery capacity incorrectly.

  • Open command prompt (cmd) on PC.
  • Type “adb shell” and connect your phone to PC. If the drivers are installed properly, PC will detect phone and you will see the device codename on command prompt.

In addition to battery capacity, you can check the battery health percentage with a simple math formula. The actual capacity in the technical specifications of your device and the current capacity you calculated above, together with the formula, will give you the percentage of battery health. The required mathematical formula is (actual capacity / current capacity)*100. An example, (2386/2800)*100. With this formula, you can determine the battery health percentage. 2386 mAH is the current battery capacity, while 2800 mAh is the actual battery capacity of the Pixel 4.

  • Open the text file in the last compressed file you extracted in a text editor and search for “healthd” in it.

The “fc” value in the healthd line shows the current capacity of your battery. According to the value “fc=4320000” in the screenshot, the current battery capacity of the device is 4320 mAh. The formula (Actual capacity / Current capacity)*100 can be used to calculate the percentage of battery health.
