When i got my nexus i was struggling to get over 2 hours on screen time, and flashing faux123s kernel and under clocking and under volting didn't help much either. I thought about getting the core Disabler app but I'm 15 and my dad wont let me buy anything.
Then i stumbled on the kernel tuner app.
I noticed the kernel tuner app wouldn't work with faux123s kernel though. The settings wouldn't stick. But using francos kernel i put the last 2 cores on the lowest settings possible and pretty much just made it a dual core. The phone hasn't slowed down whatsoever and in the ~45 min I've used it its only gone down like 10 percent!
Tell me what your setup is for great battery life!

Latest faux kernel (004m_r2) + paranoid android rom + underclock to 1.2ghz + eco mode + intellidemand governor + gpu underclock to 325mhz
gives me 5h screen on time with more than 15h of idle time.

There are different settings, Ondemand, Performance, etc. What should it be set to to get best performance and does the Set to Boot box be check marked off?
You mean XOOM overclock, right?
interactive is more responsive and use a Tad more resources than ondemand. For the XOOM being dual core interactive is fine. On demand requires a signal to increase speed whereas interactive just does it. I wouldn't set at boot until you know your settings are perfect. Set at boot sets the speed at boot rather than having to go in and raise or adjust speeds.
1.5 ghz and interactive work wonders for me.
Lol I'm probably the only one but I love performance/start on boot. My batt still lasts days and I never have to worry about touching a thing.

Hmm, that's weird. I have a higher benchmark score than you, yet my cpu is just 1.3ghz. It only comes to show benchmark scores are quite useless when it comes to performance testing. I'm on stock rom btw.

im on stock 4.2.1 rooted.
used nexus tool kit to temp boot into TWRP only to flash motley A33 kernel.
left all settings alone.
adjusted CPU speed from 1500 to 1700 and left everything else alone.
with my daily use i can get about 2 days of battery power mainly streaming netflix at night for about 3 hours for super natural.
this bench mark is fairly consistent at 1700, if i drop to 1500 CPU then the score drops back to around 5500.

Hi, you could try with this nice app called Tegra Overclock. I've been using it for quite a long time now and I really like it. It's very simple and you can REALLY set how many CPUs you want online + there are also some other options for OCing etc.
Oh and btw, I just tried that app from the HTC One X thread that you pasted and unfortunately, it doesn't do the job. :/

No problem. I hope that It will help you with your battery life.
also cpu tuner and trickstermod do the job pretty well. If your aim is to save battery check cpu tuner out
But seems that trickster mod dont save those settings for me...
Multicore Power Saving
always set to 0
Max Active CPU core
always set to 1
No way to fix them (various rom and kernel tested).
AND
Seems that tegra overclock fired up my CPU (CPU never goes under 1000 Mhz but always on max)
my phone after few minutes reboots in bootlop cause the temperature reached !
I reinstalled the ROM!!

You need to set up min/max cpu that way u wont be stuck on max cpu speed and overheat your phone.Tegraoverclock is fine but i am kinda used to SetCpu app.Download cpu spy from market and watch deep sleep that way you will know whats going on with cpu all the time.BetterBatteryStats are fine too.
i have compiled a nexus 7 kernel similar to this http://forum.xda-developers.com/showthread.php?t=1903304 but for 4.3 roms the main theory for this kernel is less heat and more battery (i was able to get 7 1/2 Hours SOT With 2 Days Standbye)
These Are The Features
1.vdd_core/vdd_rail ,emc, pll_c, host1x, GPU, CPU Pre Undervolted
2. CPU LP Overclocked To 666MHz
3. Speed of GPU 2d/3d/vde etc set at 400 mhz (close to stock of 416) (Also 228MHz GPU Step Decreased To 215MHz)
4. 1300MHz Quad Core Patch
5. Min Backlight Level 5
6. host1x Underclocked From 260MHz To 255MHz
7. Some MISC. Tweaks
8. FSYNC TOGGLE
Tell Me What Your feedback Before i make a thread in development section
it has Mkernel Ramdisk So it should boot on all roms ive only tested cm10.2 though (i will not be adding voltage control as i think this kernel has a good undervolt 75-100mv undervolt on all frequencies)
Enjoy

Not sure why you think we're being closed minded? Some people post on here claiming battery life of 11+ hours, so 7 might not be that good, alternatively you might've just increased from 7 initially to 7.5 now. Wouldn't be worth my time, given the problems I've had flashing kernels before, if the increase was hardly noticeable.
Doesn't hurt to look into stuff a bit more before we flash something completely new with little info.

I honestly don't know what all the tweaks are. I only use that combination since it is said to be stable. I may just switch back to stock.
