Battery stuck in 99% and not show their real battery percentage.

[kararhussain384]

Hello everyone.

Recently I've bought a laptop and encountered an issue that is annoying. The windows 11 battery indicator won't properly show much % I have left and stays stuck at 99% while charging or unplugged and the battery are not showing the real battery percentage. it's just the indicator is giving false readings plus no longer alerts me when the battery is low.

I reset my laptop and troubleshoot the battery driver, but it didn't work. Any help would be much appreciated.
