As far as I remember, there was an idea to kill stubdoms after boot, which
would both reduce risk (as stubdoms run in PV) and CPU+memory overhead. I
cannot try it right now, because I haven't installed Q4.

You can sort reduce

Hello,
I was able to improve battery runtime following the tips from this thread:
I've switched all my AppVMs to virt_mode = pv, using:
dom0: qvm-prefs --set virt_mode pv
In order to monitor my battery runtime and battery discharge rate, I've setup a
small monitor in my xfce4-panel:
1)
Another partial workaround, you can change virt_mode from hvm back to pv for
trustworthy VMs, like vault, etc...
The bug: https://github.com/QubesOS/qubes-issues/issues/2849
For me it amounts to an overhead of 10% x cpu core per hvm, according to xentop.

Thanks for the hint.
Honestly I can't believe that
