Hello,
I'm am running version 4rc3 on my X230 and I am suffering from a very
reduced battery runtime.
Under Qubes 3.2 I was able to get 10 to 11hrs of battery runtime with
"tlp" enabled and powertop optimizations.
Runtime is now reduced to ~4-5 hrs under Qubes 4rc3. I have installed
tlp and powertop in dom0 but am still far far away from my excellent
batter runtime under Qubes 3.2
Any ideas what is 'wrong' with 4rc3 or what I am missing?
Are there any power optimizations missing in the kernel? workload and
AppVM configuration has not be changed.
Any ideas would be great as I need to work lots of time at the
customer location and battery runtime is as important as security.
Running out of battery after half a day adds a lot to security but
unfortunately affects productivity ;-)
Kind regards

Increased CPU usage is a known issue. You can see it in the 'xentop'
listing.
This may be one of the core tradeoffs when moving to R4.0.
