Power calibration - battery level drops suddenly in ubuntu 20.04

  • 772

I shifted to ubuntu 20.04 from windows 8 . Now I have some problems with my battery.

  1. When it is around 20% it immediately drops to 5-6% and then shut down

  2. I charged it to 100% but as soon as I remove the plug it goes to 91-92%

I had tried power-calibrate -R -r 20 -d 5 -s 21 -n 0 -p but nothing changed.

shutdown battery charging 20.04
