tried a couple of different kernals over the past few days too..
was running ninpo 2.02/2.04 and 2.05 for the past month until this week.
saw ninpo 2.1.1, flashed, and it drains battery like no tomorrow..
then tried speedfrey 2.2 cause saw the benchies in xda and it seems to have the best (idle) battery life, but it gave me the warm battery when im browsing, and there is no way to control the clock or voltage. However, the battery life does seems to be better compared to ninphetamine 2.1.1.

trying speedmod T27 now, just charged it to full, no voltage control, but clock control seems to be working.
will observe and see if it'll warm up when im browsing, and see hows the battery life..

Mine works at 825mv, goes coma at any lower value..

I'm on ragemod t26, based on speedmod t26 but allow undervolting, which is needed to solve the heat issue.. So far so good..

go with ragemod if you wanna have more things to play with in setcpu..
its based on speedmod, with added function of UV

Day1 with this kernal, unplugged @ 7:30AM today, phone is still left with 55% now..
Data on, Exchange push mail on, hotmail push on, launcherpro facebook sync every 5 minutes. surfing and reading on and off..

Left with 30% now...20 more minutes to 13 hours.. I'm running this@1.2 ghz without any uc..

Mine is almost 14 hours now,hspa on 24/7.. 22% left now, unplugged since 730am.

UV will definitely help this..

second this...
i find the full brightness of SAMOLED screen to be too harsh for my eyes..
so i had timerific to automate my brightness settings based on time, to have the optimum brightness whenever i'll be (routinely) throughout the day..
the highest brightness i have is only 35% for daytime outdoor, indoor will be 25%, and when im sleeping, it'll be 0%..

with my previous phone, the brightness had to be on 100% most of the time except when i sleep..
