My mistake. I've move back to 4.19 and CPU is at 75° minimum on idle... But my mistake is when I'm on 4.15, CPU temp is not showing at all.... So the temp is maybe high even on 4.15.
So I'll stay on 4.19. 1h30 battery life from 100% to 10% only by using chromium and the terminal mostly... still bad when I reach 3h on windows.. and this laptop is supposed to have a 6 hours battery life.
