Results from Undervolting? - Samsung Galaxy Nexus

What kind of results are you guys seeing from undervolting this phone? Are you seeing less heat and an increase in battery life? Thanks. I'm considering rooting my phone so I can improve these two areas.

Nice to see you posted in the DEV section!
Yes on both account.
I find that using a 1.2Ghz UV no OC with the voltages below work quite stably:
1150
1050
950
850

I don't see why it is so hard for people to follow the rules.... smh

How are you all undervolting? Does it require you to flash a custom ROM or kernel?

Overclocking above 1.40Ghz

Hi, i am currently using a kernal that is clocked at 1.42Ghz, see link below. Everything is stable and super smooth, i would like to know if there are kernals with a higher overclock than this and if other gnex are stable at them frequencies? Want push mine to see what its capable of.

If you read the UV/OC thread in the Dev section relating to UV/OC patches, you can see why overclocking past 1.4 isn't very stable..

Yes I have already read them, I'm currently on a Max frequency of 1.42Ghz + UV which isn't supposed to be stable, but I feel that my phone is capable of handling this, therefore I would like to know if there was anything else out there to see the maximum capabilities of my phone

What kernel do you use? And how is it battery life?

Hey guys i am new in this nexus forum, lil bit confuse what kernel i would try, how was your experience? And post your battery life here.
Thank you.
And i need some clue for how much nexus can handle UV, post your settings too.
Mod, i dont see any similar thread here and if this is against the rules feel free to close this
Thanks

Using trinity atm.
This is one of the smoothest kernels in my oppinion.
And the vibration control is a must for me
I get around 3h of screen on time on normal use

I usually dont mess with the voltages so i guess they are all stock

From what I know no extra apps needed, and I don't think it adds say an hour of battery life but it does add maybe 10 - 20 minutes. Obviously I can't run the exact same battery tests over but it does feel like my battery lasts longer. Could just be placebo though

Currently trying out the Jame Bond Kernel. The attractive part of it is that it's already undervolted and so far seems stable. Feels like i get a bit of extra time, but it isn't a major difference.
JameBond 3.4 and Franco milestone 6 are the kernels I use..both give great battery but JameBond 3.4 is pretty stock and Franco has a bunch more features..

So far I think staying stock is just as good as running a developed kernel for this particular ROM imho, especially when you want to get the most battery. I use SetCPu and will run min 486 and Max 1350/1404. SmartassV2 and Zen or cfq governors. I don't play many games on my phone, I have tablets for that and they are tweaked as high as I can go and be stable. It's all about what you use your phone for, most times when I benchmark it seems the higher frequency I push my score actually will get worse, might be I'm need to up my voltage, but I don't mess with voltages much. I will follow the developers guidelines for undervolting if I'm trying to squeeze that extra life, but I don't worry about it that much. Best way for me to extend my battery life is start turning things off when they're not needed. All the things I try with my devices I have learned by reading on the XDA forums, and by far the developers for our GS3's are the best and I'm very thankful for all they give up to give us these awesome roms, kernels, and not forgetting about the theme developers to make or phones run fast, operate smoothly, and look great. Without them might as well buy a fruit product, just kidding I would get a flip phone before I would do that. .... This was meant to be a quick reply, just got off a 14 hr work day and I'm just rambling a little, I hope my reply makes sense.

collection of minimum voltages available?

Hi.
Is there a thread with a collection of reported flawlessly working minimum voltages for the GNex?
Push? Is there nothing?
There might be some dude. I found this one but doesn't have that much info http://forum.xda-developers.com/showthread.php?t=1618048
The best way to undervolt is doing it your self. Not all devices can handle the same values, even if the are the same model. You an use trickster mod(to change voltages) and stability test(to test of curse) to find out the lowest you can undervolt your phone. Search on Google and you'll find guides to do it.

Let the phone do its thing with smart reflex. Imo the stability risk is not worth a minimal battery life improvement but if you want to undervolt anyway start by lowering everything by 100 and then increase by 25 at a time if you have stability issues or freezing. There's not an easy way unfortunately as some chips undervolt better than others.

Best Kernel for Overclocking Galaxy Nexus

I'm thinking of flashing a different kernel to my Samsung Galaxy Nexus so I can overclock the CPU/GPU. I've noticed that franco.Kernel and Trinity seem to be among the most popular kernels, but I'm not sure which one to choose. In your opinion, what is the best kernel for overclocking and why? FWIW, I have the Verizon model of the phone (toro) and am currently running CyanongenMod 4.1.2, which is based off of Android 4.2.2.

Antutu or CF bench are good apps.. And a warning: overclocking will decrease the life of your phone! Be careful! If you want to use your phone a little longer I wouldn't do it (I wouldn't anyway because I think this phone is very fast especially with Android 4.3)..

Hi,
I've decided to bump this thread because all other GNex OC threads are very dated.
I recently received the extended battery 200mah and I'm ready to overclock. I wish to retain battery life to have screen time 3-4 hour on moderate usage.
I'm current rooted on stock ROM, and I wish to simply stay with stock ROM provided battery life will remain the same (perhaps I have to undervolt)
I want to hit 1.5GHz CPU and 384MHz GPU...which is what the OMAP and PowerVR SoC's true default clocks.
Given my circumstances of stock ROM, which kernel would give me the best stability/battery life? Any kernel that somehow has OC settings built in or do they all require me to buy setCPU?

They all use setcpu or trickster mod. Regarding the kernel you just should try some out.

What type of OC are you running?
Do you actually notice it day to day usage? I cant think of any apps that could benefit from it besides gaming which I do very little of on mobile.
How has it affected your battery life?

I don't OC myself. I want my gnex to last some longer. OC will wear out tour CPU.. I die it once for a day maybe two but didn't notice any improvement. I was at 1.5 GHz or something.. I think it may have some speed improvements but your battery will drain like a maniac. If you don't game I suggest you underclock: even more battery life with no speed loss!!
