valaka I have a similar pattern, with the addition that location services are always off, and almost constantly on airplane mode (at work and home), with moderate use. These should decrease battery drain in theory. Though i have tailscale running 24/7 which in theory should increase battery drain. I charge to 80% aswell and when going to sleep i have +-20% left, on a pixel 9 pro, and i percieve this as good.
Though that 'good' is compared to my previous note 20 ultra.
