I’ve been hunting this problem for a while but can’t seem to pinpoint it. I’m comparing two fresh installations of Fedora 32 vs 33 to each other on an Thinkpad 495 (AMD Raven GPU).
On Fedora 32 gnome-shell reports a remaining battery time of ~10 hours and powertop a consumption of close to 4 watts.
On Fedora 33 gnome-shell reports a remaining battery time of ~6 hours and powertop a consumption slightly above 6 watts.
I’ve tested kernel 5.8.18, 5.9.13 and 5.10.0 - the kernel does not have an impact on the idle consumption.
The major difference between 32 and 33 would be gnome-shell 3.36 vs 3.38.
I’ve asked the same question on reddit. While the majority reports a similar battery life there are a few (and most importantly, also T495 users) that report the same regression in battery life.
What has been your mileage with F33 on similar hardware?
