I figured that undervolting would help with battery life and any heat issues. Does anyone know any undervolt settings that work well?

If so, does it help your battery life? and share your settings please
underclocking to 800mhz has no impact on performance AT ALL unless your playing games even still, not much of a difference.
has a pretty good battery advantage with that being said. I keep mine underclocked to 800mhz and have no issues lasting pretty much the whole day with moderate to heavy use
I've been fooling around with undervolting.
When setting them -25mV nothing much seems to happen, no gain or loss. But when I set them -50mV or lower, I get a massive battery drain.
Is this a normal problem?
I don't crash or anything, the battery just doesn't last.
The very act of undervolting should be saving you battery, because undervolting makes it so that you use less energy at each clock speed.

It can, if services start crashing in the background and it voids deep sleep mode. You'd better just leave it default or try to nip off v's in the maximum freq department.
I thought an Undervolting thread would be good for me and I'm sure it will help others. Messed with it a little bit on my Inc but haven't on this phone yet.
How much do you undervolt by?
How much better is the battery life?
Any kernels that work better with undervolting in your opinion?

Well, it's not really needed.
I think most kernels already undervolt themselves to the possible max.
I know Franco has something called Smartflex, which takes in a bunch of calculations and undervolts it at the most optimal level (I think) and undervolting manually doesn't give any more real world battery savings compared to it.
But either way, I'd recommend Franco kernel for some of the best battery life.
Straight 175 seems to be safe for most people. I can undervolt lower. I can UV much lower but then I get a reboot at least once a week. The nexus is so efficient at many things uv'ing helps but doesn't impact usage that much. Honestly I don't think you get but about 30 minutes tops extra screen time and I'm being very generous. Uv'does help keep temps down and helps longevity of phone life.

Undervolting shouldn't be relied on for better battery life. It is such a minuscule amount of electricity change. The only thing undervolting should be used for is stability in OC.

So has anyone overclocked their t989 passed 1.5GHz and noticed any major battery drain? I was wondering how far you can really go up, max being 1.89GHz and at what point do you really notice abnormal battery drain?
For the people that have been overclocking this phone for a while now, what are your opinions on the best max frequency above 1.5GHz to clock to while still keeping decent battery life?
Overclocking isn't exactly a battery friendly thing to do, you will see battery drain if you clock to higher frequencies. My only advice is don't oc too high if you want to keep battery life in mind. Going to 1.67 or 1.72 should give you a decent speedup without murdering the battery.
I run mine at 162 its no diff in voltage from 151 at least on uber kernel it is.. Also try to under clock the the freq until or happy and no random reboots
