High battery drainage Xperia 10 III

Anyway, now that Jolla switched to using schedutil for 10 III’s all 8 cores, and that several people tested using lower minimum frequencies (e.g. 300 MHz) for all cores and also other governors (e.g. ondemand), none of which gave any noticeable power drain reduction , neither during use nor in standby, we already came to the conclusion that it is all in vain because the actual reason of 10 III’s high power drain lays elsewhere, most probably in the AOSP layer.

Maybe, but there are area of improvements:

• The bluetooth crazy CPU usage creates battery drain [solved]

because as far as I see the power management policy is disrupted by deamons that should sleep in theory but instead they are alive for too long time in CPUs and there are significant amount of CPUs used by kworkers and rcu_preempt. I never had to do with a smartphone before now but it is a normal shape of activity in a Linux embedded system.
