Thinkpads have some battery managment utility that work under linux and
avoid charging battery at 100% and keeping it charged when power supply is
normally connected. Charging and descharging decreases battery life, but
also keeping the battery always at 100% decreases battery life.

These utilities work perfectly under arch-linux with a x230, but installing
them in Qubes is very complicated. There are some suggestions on this
mailing list, but it is too much difficult for me.

I've been using Qubes on my laptop for more than three years, and my
battery is fine.  Running on battery lasts six hours or more, which
is somewhat less than a normal Linux distribution, about 30% less I
think.

As there are more than 6 VMs running all at the same time, I think
battery power lasts very well under Qubes.

Mike.

[dark wizard]

Hello, Qubes Community
How does Xen manage laptop battery. Can in kill it quickly?
Is it compatible with laptop power management technologies and drastically 
affect battery life?
