Still using battery like there's no tomorrow..
I found that MAPS was using battery, must have been Latitude (now logged out)
I've now got all SYNCing on manual, GPS off and WiFi off when out of house -- got 3G running all day
ROM Ginger Villian 2.3.1 (0.8 for HTC Desire)
Kernel 2.6.35.9-defrost-bravo
Any ideas

I stuck the CFS HAVS 875 kernel from Villain Setup on mine shortly after installing 0.8. Standby seems pretty good - subjectively it might be burning a little more juice than my most recent DF kernels did when in use, but after only a day or so it's hard to be sure. There's certainly not a lot in it.
Turning mobile data on/off with the notification bar widget seems a little more finnicky than with DF, and camera is more limited than the CyanogenMod one in DF, but its still early days. Otherwise seems to be going pretty well so far. Even LP's 3D app drawer is working for me, which it wasn't in GV 0.1-0.6 (I never tried 0.7).
And strangely, Angry Birds is smoother than I've ever seen before

Never actually used 875 on DF. Got as far as 925, then EViollet's kernels, which are 900, and I don't know what vork used. So 875 here is a bit of an experiment for me - don't like instability, but as the phone seemed pretty tolerant I thought it was time to try. OK so far...
Did have one reboot from standby with vork Xmas though (in line with the theory that what works for one of us won't for others!). But I'm not sure what the min voltage on that kernel is.
Dan, you say 925 seems to give you better battery life? Ah, I see, different version as well as voltage.

Well, with a bit longer running I'm coming to the conclusion that the 0.8 875 HAVS isn't bad for battery, but not up with the best I've used with DF. Early days, of course. But what to try next? Not as many choices as Froyo, but still a few
Well I've still got 33% left... best yet on GV
I have had 2 reboots though in less than 24 hrs!!
What's would you recommend for battery life and stability??
there's a "0.8 SVS + CFS 1113Mhz" and a "0.8 SVS + BFS 1113Mhz" in the Villian settings that don't say anything about being unstable
what does all this stuff mean?? (I understand the clock speed!!)
Cheers

SVS is Static Voltage Scaling, which means that there's a fixed voltage for each cpu frequency.
HAVS is Hybrid Adaptive Voltage Scaling. With this the voltage is adjusted according to both clock speed and temperature.
In principle HAVS kernels can use less power, by running at lower voltages. But different handsets have different tolerances for this. Sounds like the 875mV minimum of this kernel may be too low for yours.
The HAVS 925mV version might be more stable - this is the same principle but a higher minimum voltage. SVS kernels don't typically go to as low a voltage, and so tend to be most stable. The default kernel will have been one of these.
CFS and BFS are different scheduling algorithms (how cpu cycles are shared between tasks). With 2.2 BFS was (in my experience) more responsive, but with 2.3 everbody seems to report CFS being better.
The 1190 SVS kernels have stability warnings because not all phones can cope with the high overclocks, but then it's up to you whether you select that. That will anyway reduce battery life, so I doubt they are of much interest to you.
I'm currently experimenting with other kernels apart from those downloaded via Villain Setup (tried vork, currently trialling eviollet's GB kernel, not tried coutts' yet).

There's a section for AOSP kernels in that post. All 3 have versions which work for Gingerbread, as well as Froyo kernels.
Of course there's no guarantee that these work better that the GingerVillain kernels - it's a matter of trying things and seeing what works for you.

So it's behaved as the theory suggests: the SVS kernel uses higher voltage, and more power has been used. But it's stable.
You could try the HAVS 925 kernel - that's a higher min voltage than the 875, which might be enough for your phone and should use less power than the SVS.
I gave one of EViollet's GB kernels a spin today, specifically the HAVS-AXI-CFS version of the "ManU-Version 1.0" kernel. This is based on an older kernel, which many people have found to use less power, and worked fine for me. There's also an SVS version. The min voltage here is 900 mV, so a bit higher than the 875 (875 seems to be problematic for a lot of people).
I'm currently trying the 2.6.37 Vork kernel (HAVS-CFS). Did briefly try the Coutts kernel, but had a few problems (FCs, and then the phone locked up when in usb disk drive mode - had to do a battery pull). But your mileage may vary. Vork is nice and responsive, and screen-off current consumptions is as good as any of the others, but too early to say much more yet.
Why am I hacking so much today? Had a minor plumbing problem, which is one of my pet hates, and needed to unwind
