Seems the wifi is not turning off while the device is on sleep-mode (and stamina mode too). I cant remember if that was from the beginning or if it broke the last 1-2 days...
Settings > power management > location based WiFi, is it on?
Yes it is, but the most time of the day im on wifi areas... 😕
Stamina Mode says that is stopping the wifi while on sleep, but as i see it stay on.
Simple, turn off that feature.
Did you mean the wifi based on location? If yes i did it and wont helped.
Boot on safe mode for few hours and check again, most likely its a third party app acting up

Very good idea but wont helped, i put the phone on safemode and sleep for about 20 mins and the wifi remain ON. 😕
Is it mabye normal?
Well the wifi will be on unless you turn it off, if you turn it off and it stays on then repair your phone with PCC

Stamina mode should kick in after 5minutes or so.
