Wanna save some battery?
Have a look at this, my experience on undervolting my Nexus using Franco kernel:
Red - system not stable
Green - system stable and runs without any crash

the 3 minutes were tested under heavy duty - frequent task switching, video streaming and file system stressing. I'll update the document once I find any unstable voltages, so please come back for updates if you wish.
btw, everyone's phone is different, so the voltage settings may not work on all phones.
Here's what I've been using

If you wanna take the time to play with the voltages, you will get better battery life than using SR. I watched SR and it was running a good 75+mv higher across the board than when I underclocked it. Its been just as stable and smooth manually undervolting.

I was reading about few people showing undervoltages and stuff but I get really lost I dont want to mess up my phone.
I am running the lean kernel or imoseyon and I flashed it via the franco kernel app it has his kernel and the one I said.
Now I have no idea which settings to choose and which are safe... can anybody help me out?

Some people should only use SR, since they do not know how to uv, and troubleshoot that by themselves.

So, what's the point OP? Wonderful chart for your own use, but does little for everyone else.

Its a reference for others, not a "guaranteed to be the best voltages" chart.
Sent from my Galaxy Nexus using Tapatalk 2
I've used these as a good reference.
The voltages have been stable on my Galaxy Nexus. They are good to reference. In most cases the most I could undervolt from these settings was 25mV. So far, I've had pretty good battery life. I'll definitely vouch for houzuoguo's spreadsheet.
Anyone have real statistics and battery readings that prove undervolting is even worth the effort?
where is the test? i dont see any testing

I'll try to do some identical real world testing with my normal usage with Smart Reflex on then with my undervolt settings. I should be able to report back in a day or two.
The Results
Okay, so here are my results:
ROM: AOKP build 36
Kernel: Franco 166
Governor: Interactive
SmartReflex enabled
CPU: 192MHz to 1036MHz
Battery: Stock 1850mAh
3G on when screen is on with occasional LTE usage. Never used WiFi.
The first 3 attachments are without undervolting.
Attachments 4-6 show my undervolting settings.
The last 3 attachments are with my undervolting settings enabled. FYI, I used the saved values for the last 3 attachments.
If anyone wants anymore information on app usage just let me know. I have a few more screenshots, but didn't feel like uploading a ton of files.
I'm not sure if these results are sound, but I just updated to AOKP build 38 and Franco Milestone 4 kernel. I'll continue to test and see if these results are consistent.
Doesn't look much of a difference with doesn't it? according to CPU Spy and screen on time, as well as looking at 384MHz and 1036MHz CPU.
Thanks for the suggestions Houzuoguo. I am running LiquidSmooth-ICS-v1.5mr1 and Franco Kernel Milestone4
I took your settings and raised them all by 25.
I used Set CPU to set them and i also set the CPU to ondemand and dropped the CPU speed to 1036.
Are you using Set CPU to do this?
My Results
Thanks you very much BrandT90!! I tried some of you settings and changed some values. It's incredible. 11 hours!!! :good:
Look at the screenshots
ROM: Paranoid Rom 2.16
Kernel: Franco Milestone 5
Governor: Ondemand
SmartReflex enabled
CPU: 230MHz to 729MHz (but I use the schedule feature in SetCPU for Apps which need more CPU)
Battery: Stock 1850mAh
I set my brightness to automatic and tweaked the settings in cm10.
3G/Wifi: Juice Defender manages them.
Without undervolting I had the same results like BrandT90. (Look at his first 3 screenshots)

Ever since i flashed francos kernel for the first time i failed to see any difference whatsoever in batterylife or performance. 4 versions of franco kernel later and still no change. Even bought his app and tried undervolting. I accidentaly uv'd by 100 in the 700 category and none of the side effects were happening so i tried undervolting all by 200 and even setting on boot. Nothing happened. I then flashed jame bond kernel and nothing happened. When i tried flashing glados kernel it just froze on boot. I experimented with all of them for at least a day and except glados which didn't work they all showed no difference than stock regarding battery life or performance. What could be the cause of this?

Kernels don't have the profound effect you might think on this phone. Not nearly as much as devices I have had in the past.
I'm aware of that, but still. No difference whatsoever? Even when i intentionally try and break it by undervolting by 200?
Sent from my Galaxy Nexus using Tapatalk
What did you undervolt by 200? Some speed steps can get away with that.
What ROM are you using?

Adrynalyne! Its good to see you here!
Yeah, on the Fascinate, Kernels had much more of a profound effect. I can't say the same for this phone. But the OP said that he purposely tried to Bork his phone to see if it worked and it didn't even touch it. That's really strange. I can purposely try to Bork mine and do a pretty damn good job of it.

Some kernels had broken UV interfaces that wouldn't undervolt the kernel and would allow you to undervolt by absurd amounts. (though it wasn't actually doing anything)

Well, are all the most popular kernels broken? Franco, glados, jame bond? I'm more inclined to think the problem is localized (either me or my phone).
And i'm running aokp 20, btw. Had 19 and milestone2 before those, which were all installed after full wipes (before anyone suggests that).
Sent from my Galaxy Nexus using Tapatalk
Your not the only one with this problem as I too have seen no change in battery performance on my gnex. I'm also using aokp 20 and Franco's (14.4). What I don't get however is that my buddy seems to see significant improvement in his phone while running the same rom/kernel combo
I've had some friends do some tests for me and run stock kernels for a while.
The differences in performance and battery life were menial between custom and stock.
What about all those people that claim seeing improved battery life? Not to mention those impresive screenshots of battery stats that show numbers i have yet to even come close to.

Many of those screenshots are sleep time.

naturally. also, data calls are a huge battery drainer, even with excellent reception, when actually using the phone. the same with wifi.
to give the op an example, this last night i forgot wifi on. connected to my home network. the phone slept well (something woke it up in the middle but for a very short period of time, probably gmail), and i only lost 3%. i normally loose 1% in 7hrs approx., so it wasnt so bad.
on the other hand, if screenOn is true, it will obviously drain faster..

Tried a lot of combinations, but at the time of writing the original post i had been using aokp 20 with franco 14.4 for a while. I am currently trying aokp20 with trinity 384mhz gpu.
Also i lost about 2%/hour with franco in standby. I had mobile data connected and autosync only for google account + yahoo mail, all set to sync each hour.
Waiting on trinity now. Curious if i notice any difference besides the lack of franco's blueish tint.

My own or stock. I experiment a lot. Currently I am running a custom with a tweaked deadline scheduler, and a slightly different oc method for gpu and cpu than everyone is using to 1.35ghz. Stock voltages, tweaked ramdisk for filesystem mounts. Stock sleep profile of 350/700 on Interactive. Not using Setcpu to overclock at all. I set the power profile in fw-res to include the extra speed step.
So far so good, but its too early to tell. I went to bed and work up 9 hours off battery with 99% remaining. So its definitely deep sleeping fine I won't know for a couple days on whether it sucks battery dry or not.

exactly. I used to go crazy doing this and that, disabling this and that to try to get 20+ hours that people were getting on stock battery. Then I came to realize that the screenshots are probably mostly sleep time. Me being a very social person (text, IM, Facebook, and Tweet a lot) there is no way I was ever gonna get anywhere near 20 hours on stock. So I bought a couple of spare batteries, turned stuff back on, turn the screen back on brightly and enjoyed the phone and its great screen without worrying about battery life

Ill be as honest as I can. I just had two nexus and installed two different roms and and two different kernels....I believe they don't do anything as well..And I thinks its placebo effect when people are saying there battery's are better or the screen is smoother....I see not much of a difference even in stock...yes the benchmark may go up but that's means nothing really....

I've used cm9 and aokp the past month and tried the stock Kernels that come with it and Franco's. One thing is for certain. No matter combination I get horrible battery life. If I run stock android with my extended battery including various Widgets I get 24 hours battery life pretty easily. Moderate usage and some heavy usage. With cm9 I'm getting maybe 15-16 hrs with aokp maybe 8-9 hers and I'm using Franco's kernel right now. I don't understand this. People talk about how much better the battery life is with various ROMS than stock but I'm not getting it. I'm getting like half the battery life I was before. Any ideas?
Sent from my Galaxy Nexus using Tapatalk 2
I can relate to you. Was in CM9 and Franko's kernel and as you said, horrible battery life. I went back to stock but this time I did not install apps thar would require services running (well I have to run WhatsApp so that's the only one running besides default abdroid services).
I am seeing better battery life this way.
The next step would be to install CM9 and restore all my apps to see if I can replicate the same battery life.

you need to find out what apps are keeping your phone from sleeping dude its not the ROM or Kernel if you want to find out you can use better battery stats or just read the permissions on your apps otherwise its probably cause your on your phone too much with the screen on first show use a usage screen shot then how many apps you have we can narrow it down

I'm getting about 1.5 hrs screen time. With stock in was getting 2-3hrs. As far as apps keeping my phone from sleeping. I'm running the same apps I run on stock android when I was getting a full day on average so not sure how they would run different because I'm on a ROM.

I used that better battery stats app and apparently there was audio something (sorry can't remember the exact words) causing partial wakelocks, read some google search results and disabled the lock screen sound in aokp and it went away, go figure?
I swear my battery life is better with the kernel that comes with AOKP rather than franco, which was a bummer since I'd just bought the franco updater app, perhaps just my imagination or maybe something just needs to be tweaked
Well, this has pretty much nothing to do with the ROMs/kernels, you flash to the device. If you use the device for heavy gaming, you use loads of apps etc. the battery life will obviously be bad, because the CPU needs the according CPU clock speed...
Underclock the CPU, or better: Get AnTuTu CPU Master pro, and set the profiles, underclock screen off, to 700 MHz, and every other proile, where you do not neccessarily need the device to that speed, not below, otherwise it will just crash... That way you have the best battery life, for your usage, so basically, every time you switch the device's screen off, it will save a hell of a load of battery
Under clocking doesn't do much for battery life contrary to popular belief. It just increases the time it takes to process a task. It might take 1s at 1.2ghz vs 1.8s at 800ghz to complete a given task for example. So yes the cpu will run at lower speed and voltage but it still also take longer to return to idle.

Well, I don't really mean to break this, because it is right, but not completely...
Underclocking & undervolting, when the device is not in use (Screen off) saves loads of battery...
And because it's a dual-core, it takes mostly just as long to open an app at 700 MHz, as when you're doing it at stock clock speed, or voltage or higher.. So, in that case...

Not sure how this wouldn't have to do with the different ROMS and kernels since I stated what battery life I was getting with stock vs using a custom kernel and ROMS. I'm giving a comparison of my battery on each with the same usasge and they are different.

Nyan Colonel was originally created for the Epic 4G as an effort to bring all of the features from other Hummingbird devices to the Epic. Now I have used my upgrade on a Galaxy Nexus and have been trying many different kernels and every one seems to have some features and be missing others. I have attempted to add as much features I can while still keeping the kernel lean and fast with great battery life. This does not require you to be some crazy linux enthusiast in order to modify, or charge you for an app capable of tuning it. It comes with the trickstermod app in order to tweak the kernel to your needs in case the preset settings don't fit your user type.

stock 307 however you can overclock it with the file located at /sys/devices/system/cpu/cpu0/cpufreq/gpu_oc change it to 1 = 384mhz and 2 = 512mhz it applies instantly no rebooting required and will reset upon reboot.

I initially tried the pegusus setting but my battery life was absolutely horrible, I have now switched to wheatley, which is what I have used on the kernel I was using before this one and battery life seems much better. Can anyone recommend any other settings that might help improve my battery life without killing my performance? Using wheatley on 1.3ghz max frequency with SIO.

I'm curious as to why you're even overclocked? I run 1ghz for everyday things. I'm trying to figure out which governor is best for me, pegusus sucked my battery life to, trying interactive which is met to be more geared to better battery life, I'll try wheatley next.

I'm nearly constantly on it because its basically my PC.. I can suck out at least 4 hours of screen on time. Probably can suck out 2 days with light use.

I would really appreciate it if someone could screenshot their undervolted settings just so I have something (like a benchmark) to go off of, along with an estimate of how much battery life I stand to gain by doing this. Thank you very much for any help!

I just picked up my Nexus 7, and I have tinykernel installed, and I am now using trickstermod to undervolt my device. I would really appreciate it if someone could screenshot their undervolted settings just so I have something (like a benchmark) to go off of, along with an estimate of how much battery life I stand to gain by doing this. Thank you very much for any help!

I would really like this too!
Here are the settings I am running my Nexus on. They arent maxed out, I may get some millivolts here or there but its is at least stable. My GPU is running on -150mv
One thing to note is that I have an ACPU BIN 6 CPU.

Thanks, will try to give it a go when i have the time.
Did you notice your battery life improved vastly or were the results only marginal?
What do you mean? You mean you have a better binned cpu? How can i see my binning?
These are the stock voltages btw if anyone cares:

Hi guys,
I understand that some heat when running resource intensive applications and games is to be expected but I believe I've passed into the danger zone, so to speak. When playing XCOM my CPU temperature quickly exceeds 80°C. From my googling on the matter I have come to assume that a temperature as high as 80°C is dangerous for the hardware of the device, but I have had trouble finding upper threshold limits for the model itself.
I guess my questions are as follows:
1) How damaging would running the CPU at 80°C for an extended duration (1hr +) be?
2) What would you consider the max acceptable CPU temperature to be?
3) Assuming it is as bad as thought, what are my options to reduce the CPU temperature, short of avoiding the problem applications? Underclocking seems to be a common suggestion, but I get the feeling that XCOM, or similarly taxing applications, may just fail to run or become incredible sluggish under such constraints.
My device is rooted and running Lean Kernel v2.4 along with the w03Slim ROM. Found here: http://forum.xda-developers.com/showthread.php?t=2638116
I've done similar test runs in the Temasek kernel with the recommended configurations through Trickster Mod and there is no difference, the CPU still exceeds 80°C when playing XCOM. After a week or so of googling, searching the forums, and digging through device manuals I feel like I'm spinning my wheels.
Any insight or advice you all might have is greatly appreciated.
Solved!

Does not exceeds to 80c now?
You can try a custom kernel, i would recommend you BioShock kernel, with conservativex, max freq 2.2 ghz and undervolt 25 mV... No more over warming for me, great performance and battery life

Agree with this post, conservativex is a great governor to keep your cpu in check and not over throttle itself, also check out my thread I made here awhile back and apply the 8th post down. It really helped keep the temp down on my phone when playing graphically intensive games like dead trigger 2,riptide gp2 etc. Also if you have trickster mod or faux clock(really recommended) you can scale down your max frequency, that should really help keep it cooler and you won't see much of a performance drop (if any) while gaming or heavily using your phone.

Does it works with KitKat?

Sounds great.. But i have a question.. Some settings are for ondemand based govs wich are unstable with kk... So would you recommend to try this with interactivex? Or wich one. TIA
