Is anyone else noticing very significant increases in battery life with 3.2 as opposed to 3.1?
On 3.1 I was lucky to get 1h 30 min while with 3.2 I am easily getting 3 hours.
I have an Nvidia Quadro graphics card so I am guessing some improvement in the nouveau driver is helping.
Anyone else want to share their battery life experiences?

Sounds like good news. I've found powertop very handy for monitoring power
usage. Perhaps you could use it to see how many watts you're pulling before
and after?

Good idea.
I am assuming that I need to install PowerTop in dom0. What is the safest way to do this?

You can install it in the usual way:

$ sudo qubes-dom0-update powertop
Note, of course, that the usual warnings apply about installing and running
programs in dom0. IMHO, installing and running powertop from the Fedora repo
is a minimal, acceptable risk, but of course it's up to you.

Ok I can confirm a very significant improvement in power usage.
In 3.1 with minimal activity (nothing but basic VM open) the usage is about 24W. Opening a few VM's (personal, work, etc) brings that up to about 28.5W.
IN 3.2 with minimal activity (nothing but basic VM open) the usage is about 13.1W. Opening a few VM's (personal, work, etc) brings that up to about 16.3W.
There is also an improvement in temperature. My laptop ran pretty warm in 3.1 while in 3.2 it runs cool. Going to dig into it more.
My setup is
Nvidia Quadro M2000M
Intel Xeon M1505
16Gb Ram
Given this is new hardware my guess is significant driver updates is the cause.

I am also noting increases in graphics performance, less artifacts.
One point to note for those running Windows 7 HVM is that Qubes Windows Tools 3.2.0.2 seems to be more stable than 3.0.4.1
I had issues with the older windows tools in 3.1 but the problems got worse in 3.2. The VM would randomly crash. Since updating windows tools it has not crashed yet.

That's great to hear Peter.
Things are getting better all the time. Great work Qubes team.

Do you means you have successfully upgraded tools in existing Windows
VM? Or maybe you did fresh install?
In any case, have you observed any difference in performance of Windows
VM? Especially, if did fresh install, what was Windows installation
time?

I successfully upgraded Windows Tools in existing Windows VM. Note that it took 4 tries for me to successfully complete it without crashing. I cloned the VM as backup before doing anything.

I have not noticed any significant performance increases, only stability improvement. For me though this is the most critical. I have not had a crash since the upgrade.
