Does anyone know If underclocking the CPU actually save battery life?
It would technically save an incy teency bit but I doubt you will really notice a difference given the small window of safe underclocking. When I tried it my phone ran like crap but what do I know. The way I figured it was the phone was optimized at 1.2ghz. It's like putting 87 octane gas in a high end sports car. Some people swear by it though. Just try it and see if it works for you.
It can but if it's not by much I would doubt you would notice a difference..

Very true. I would just slightly under volt it then under clock it. Like 25 to 50 mV under. Any less than that and you can run into issues. Tagraz has an OC/UC module within the app.

I like to underclock but noticed that if I underclock + undervolt + use any tweaks my battery drains faster... I've been experimenting with different mods and I know on my phone if I just underclock + under volt I get no issues.. if I run just the tweaks ( kob's or td's ) without underclockin and undervolting everything is OK... so trying to see which one is better on battery + performance...

It's been my experience on gb that under clocking from 1200 to 800 vastly improves battery life. It's possible it's placebo, as I've done no specific testing, but the battery life does appear substantially better. Oh and that is with no undervolting

does anyone use these? if so what have you set yours at? mine are sampling rate (45000), up threshold (93%), and power save bias (140). im looking for battery life from anywhere and if you could give me insight to the best settings, without much lag, id be appreciative and thank you.
Anybody?

For battery life, I'd recommend a custom kernel. If you don't want to do that, go to profiles and add one for screen off. Make it underclock to 384MHZ min and max. This saves battery a ton.

While I don't know the exact answer to your question -- I have heard that SetCPU doesn't do an incredible amount for the Incredible (no pun intended).
If you're looking for battery life, I'd probably look around (maybe Google?) for people who know how much to underclock it while the phone is not in use -- I know capping the processes really helps the battery life.

Did that and noticed some improvement, min 245 max 384. Will that make any changes?

I am actually underclocked to 883mhz on normal usage

No, it shouldn't affect it. For the most drastic battery life saver, I would consider installing a custom ROM such as skyraider 4.0. I used my phone quite a bit today and lost only 30% battery. I do have an extended battery, but still.

i have found the best kernel/rom combo for me that saves battery is MIUI and chad's incredikernel. with that kernel, your screen off will be 128 (versus 245) and it works extremely well. you will get a good full day of use, trust me..
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.

Like I stated. This may seem like an overasked question, but the parameters of the question are a little bit different than normal.
Considering how some ROMs come with CPU sleeper, would underclocking save battery?
What I mean by this is, since you are underclocking, I assume that other cores turn on more to compensate, so would that consume more power?
Or would the underclocking benefits outweigh the other cores turning on?
Thanks
Underclocking slows down the cpu/gpu which keeps them awake longer thus using more battery. Some different governors would probably make the most difference but not sure how much better battery life this phone could get.

How much can the phone be underclocked while maintaining the stability of the system?
What would happen if i set Max freq to 600 Mhz?
What is the best thing to do to save up the very last bit of juice in the battery for emergency situations where i would only need the phone and message facility? Besides switching off Bt,wifi,sync.
Im asking because i was wondering if underclocking "too much" saves a substantial amount of battery when my battery is quite low and I am "hours away" from a charging port!
And is there a way to change the carrier name on the notification drop down to whatever we want.
Sorry if i sound noobish or if a similar query has been asked before
Thnx.
Underclocking the CPU dramatically isn't going to gain you a great deal in the way of extra battery life because:
1. Unless you are heavily taxing the CPU (complex 3d games etc), the biggest drains on the battery are the screen and the radio.
2. If the screen is off, the phone will drop the CPU frequency right down anyway.
The best way to get extended battery life is simply to carry spare batteries!

Dave

I think 600mhz is way too low and counter productive or for that matter anything less than 1ghz. The phone will lag alot and you'll have freezes. You'll probably end up using up alot of the battery life trying to get tasks completed. You could try leaving the stock clockspeed 1.6ghz, set minimum cores to 2 and slightly undervolt to -25mv, leave the gpu setup to its default 533mhz and also undervolt to -25mv using a kernel that supports stweak app. Then run an app called Stability Test for 10minutes to check for errors.
Also I tried Go Power Master, which can be assigned to disable certain features once your battery hits critical low levels.

Thats quite informative. Thanx!
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
