Hello Dear MIUI Fan's!
Today I'll show you How To check how much your battery capacity has dropped in a smartphone!

You will need:
ADB Driver: (8.89 MB, Downloads: 405)
Platform Tools: (7.16 MB, Downloads: 322)

Enable USB Debugging and USB Debigging (secure settings in developer options)
After connect device to pc and open Platform-tools: unzip it to the root drive C:/

Charge  Device to 100% reboot and connect to PC
After open Command line from this folder and write command: adb devices - for recognizing connected device.

If all fine! Write second command: adb shell dumpsys battery
For example my device MI 9T, i use it almost 4 months and i lost ~140 mAh from 4 000 mAh

Decoding values in response to a command:
  • Charge counter: only first 4 number need. I have 3760( that's mean my battery have 3760 mAh when it fully charged). After you find the current capacity, take the declared capacity from the manufacturer and subtract the current one from it. You will find  what is the loss of capacity of your smartphone. Example Mi 9T (4000 mAh - 3760 mAh = 140 mAh this figure is the lost battery capacity, but do not forget about the error in the battery capacity from the manufacturer 0.5%).
  • Status. Have 5 stage:
1 - issues with reading battery info
2 - charged (not full)
3 - uncharged, but connected to usb or charger
4 - uncharged
5 -  Fully charged

  • Health also 5 stage:
1 - Excellent
2 - Good
3 - Normal
4 - Poor (need new battery)
5 - Very bad (need new battery)
  • Level - How much is currently charged
  • Scale - at what charge will the maximum battery capacity be

My Mi Max 3 lost 650 mAh using 1 year  and almost 4 months. Screen below

Guys share your screenshot about your statistics. What device and how much time you use it! I think everyone will be interested to know how much other devices lose capacity.
