For linux/macOS:

 adb shell dumpsys battery | grep level

For Windows:

adb shell dumpsys battery | findstr /r /c:level

Getting error with above command "grep' is not recognized as an internal or external command, operable program or batch file." – Yuonneyup

What OS are you on? Windows/Linux/macOS ? – Helio

I am using Windows – Yuonneyup

try adb shell dumpsys battery | findstr /r /c:level – Helio

The easier solution would be to use grep of the Android phone: adb shell "dumpsys battery | grep level" As it bases on Linux the chance is very high that it has grep. – Babyblueeyes

Yes it also worked.. adb shell "dumpsys battery | grep level" @Babyblueeyes – Yuonneyup

Is there any way to get only value say 50 instead of level:50? I have asked the question separately here, please reply #73558032 – Yuonneyup

Answer 2

You can read a file where level/capacity located

The file is located in /sys/class/power_supply/battery/capacity

In Linux, MacOS and Windows:

adb shell cat /sys/class/power_supply/battery/capacity
