In my personal use case it allows to win near 30 minutes of battery
life. As example I've picked two morning when I haven't run anything
heavy like calls in zoom.
Without powersaving:
Apr 27 10:13:42 matebook apmd: system resumed from sleep
Apr 27 10:13:42 matebook apmd: battery status: high. external power status:
not connected. estimated battery life 100% (1130 minutes life time estimate)
Apr 27 11:27:52 matebook apmd: battery status: low. external power status:
not connected. estimated battery life 50% (65 minutes life time estimate)
Apr 27 12:24:12 matebook apmd: battery status: CRITICAL. external power
status: not connected. estimated battery life 15% (20 minutes life time
estimate)
after 1h 14m I had left 50% of battery, and aftre 2h 11m had 15%.
With powersaving:
Apr 30 11:07:21 matebook apmd: system resumed from sleep
Apr 30 11:07:21 matebook apmd: battery status: high. external power status:
not connected. estimated battery life 100% (2506 minutes life time estimate)
Apr 30 12:46:12 matebook apmd: battery status: low. external power status:
not connected. estimated battery life 50% (111 minutes life time estimate)
Apr 30 13:56:00 matebook apmd: battery status: CRITICAL. external power
status: not connected. estimated battery life 15% (32 minutes life time
estimate)
after 1h 29m I had left 50% of battery, and after 2h 39m had 15%.
So, this patch allows to run the same machine on the same usage longer with
some performance penalty which seems quite fair.
