Battery drains even NB is shut down

[gix]

I have a strange issue that my battery drains very quick when my notebook is powered off.
May this be related to driver issues? I got a Ryzen 5 with vega graphic card.

This bug affects also me. Initially I have thougth that was a battery issue, but then I have restarted the notebook, went into bios settings and switched off the machine from the power button.
After one night battery was still at 100%, while if I shut down from ubuntu it goes at 15% normally. This appens since few months.
I have a Dell Precision 3541 with kernel
