Well, the connection between the battery status and the resume of
thermal zones is somewhat unclear to me at the moment.

Most likely, the commit in question changes the timing of system
resume which affects the battery behavior and it seems to be related
to the EC somehow.

Let's first see what thermal zones there are on your system, so please
send the output of

$ cat /sys/class/thermal/thermal_zone*/type
