I have been experiencing sudden and unexplained battery drainage overnight with my XA2 Ultra, and now with Xperia 10 II, too. When I have looked at
htop it has every time been
lipstick process (with a long list of parameters) that is stuck. This can drain some 50%+ of the battery on my XA2 and just last night ~25% of the battery on my Xperia 10 II.
I am quite sure this happened with 4.0.1, too, but I’m not confident enough to tag it.
Keep using the phone for a day or two
Edit: Take a screenshot.
Lipstick process acts normal.
Lipstick process gets stuck and consumes ~16.8% CPU the whole time, preventing sleep mode, leading to battery drainage.
Rebooting home screen doesn’t work, as lipstick is too stuck. Power cycle fixed the issue, until it appears again.
