UNDERclocking for BEST battery - Galaxy S III Q&A, Help & Troubleshooting

Hello, im on Temasek ROM with Temasek kernel, which can be customizable by stweaks.
I have searched but really didnt find an exact answer. Im looking for the values, profiles, that are best for battery life, yet dont want to lose much performance
Thanks for your time.

Try it urself. You can decide what's good... But if you underclock ya phone, u have to know that ya phone isn't so smooth and stable anymore!
Underclocking doesn't make more Batterylife.

Yeah, but it isn't much more battery life, I tried out, got half an hour more.... And it will be very laggy.....

you just contradicted yourself. You said that it does nothing for the battery life, while it clearly increases it. The actual effect depends on the underclock and your usage

What about undervolting? Does it save more battery than uc ?

Very very minimal savings. But it can reduce the temperature/heat.

[Q] High battery consumption

i have a very high battery consumption with any vibrant rom...
i don't understand...
1 hour in stand-by (only mobile data active)
vibrant: 7-8% of battery
nexus s: 1-2%
why?!

bullet kernel now... (juwe port rom)
You might have something running in the background. Try to use Advance Task Killer. If it does not help, maybe you should flash another rom like Revolution Rom by Ali.

Also set a Profile in SetCPU when Screen Off do 400/100 smartass. I think it helps.
i will try...however the governor was conservative not ondemand...
thx to all
Might try calibrating battery. If so battery may be shot from improper care (i.e. leaving phone in hot car.)

Check how old your battery is. You might need to replace it. Or you can just ODIN back to stock and see how long you last on stock ROM and kernel and see if your battery lasts.
Don't use a setcpu profile if your using the smartass governer. it can cause sleep of death

[Q] ICS Passion CPU setting

guys, what's the recommended set CPU settings and profiles for ICS Passion v11 to save battery life. I recently flash the new ICS Passion v11b5 kernel.

I think 1.2 GHz as a max should be good enough. As for governors, try conservative, although smartass will probably give you a good blend of performance/battery.
Whatever you do though, don't put the min as 100 MHz.
Thanks but I'm currently using 100 as minimum.
What's the issue of it?

100 and 200 use the same amount of power, hence same battery life with better performance. You don't even need to overclock, just undervolt all -25.
Using stock settings will give you both battery and smoothness on the rom.

[Q] Battery Draining

How to extended the battery life time and minimize it's draining during your daily usage of the SGS2 ?
Also is. Over clocking. Increases the battery draining ?
To extend your battery life, stop using your phone and/or decrease the screen brightness when using it.
Overclocking will probably increase the battery drain if your phone is using the overclocked frequencies.
To increase your battery life turn your phone off every time you are not using it, turn it on when you want to use it, that will get you good battery life.
Honestly search this forum there are a handful of threads that give guides and tutorials on how to maintain battery life not that difficult to search my friend.

Use it as a paperweight and that should be good enough..Or just keep having the charger in it while you are at home
anyway lame jokes aside. get yourself a decent kernel. in your case speedmod. set the governor of your choice and let the magic begin......seriously for you that kernel should be fine. just do not get to excited when the magic begins and you start kissing your phone though just do not tell us here
Hope that helps mate

Speedmod is fine on default. No need to change governor unless you want to try conservative but I recommend to leave speedmod as is.

ohh u mean scaling of the cpu
oh yeh i never change that :L
its on ondemand now on setcpu
To be honest you don't need to use any of those type of application you are better off just removing them and leaving the kernel on complete stock.

Governors are for scaling cpu as you just said. As Nikz said if you are using speedmod no point using any cpu apps as the kernel does all the work for you

[Q] Battery Life with custom ROMs

Hi there,
i am new into this custom ROM stuff and i been trying few ROM and now i am on the UltimaROM 2.3.2
but Battery going down from 100 to 84 in short time
Which is the best to have more Battery
and is there anyway removing the default SMS app and use chompsms instead ?
Nothing is best here. Just keep experience yourself with different rom, kernel and tweaks to find the best battery performance for your phone.

These things depend on how you use your phone, but system and idle seem high on your list. Screen and talking are my top two. Batteries have so many variables. I would try different ROMs and kernels.

Go to page one General and you will find stickys .
Alternative is to read the kernel posts in development section .
Or even that new fangled idea google search .

I think stock kernal is probably your best bet for battery life...
Hi everyone!
1st post on xda, but I'm new in android world!
Anyway, I'm using Omega ROM v27.2 (JB)/stock kernel and I experienced some battery drain issues. After getting BBS, I didn't able to point out what was the cause.
After many readings, I found a possible solution: in advanced WiFi settings, they advised to disable "Keep WiFi on during sleep". By default it's set on "always". They advise to set it to "never" but I prefer set it to "only when plugged in". I think it's more logical!
I don't know yet if it's efficient but I'm trying this and I'll come back later to tell you.
Sent from my GT-I9300 using xda app-developers app
you could use phenomenal kernel for better battery life. it is better than stock kernel in terms of battery life but you need to check compatibility with the custom rom you choose
Foxhound Essential .2 with latest siyah kernel
Best Battery life I ever tried - I've used Foxhound, Criskelo, and Omega JB roms but the Foxhound Essential is the fastest, ram free (430mb), best battery life performance around (8hours extensive use with mobile date turned on). Try it its great! Thanks

Try latest siyah kernel - plus Foxhound Essential ver .2 - No bloatware and best battery life performance..
I flashed Phenomenal Extreme kernel yesterday but to test it properly I have to wait for Monday when I'll be at work.
I'm not a fanatic of battery life, I just want to find the right mix between performance & battery life. For now, I found the phenom extreme not enough smooth, I'll probably change it for the medium one in few days.

Get betterbatterystats and check the wake locks! The default battery stats from our phone can't allow us to deduce whether there is an issue

My best results with battery life has been with Phenomenal Extreme and VikingROM. I got about 6 hours screentime with wifi, sync, and lots of gaming. Though i think you can make almost any rom or kernel last about 5-6 hours screentime if you check your running processes and apps running in the backround.
I hv tried lots of roms
Psycho rom XXDLJ1 v 0.0.1 is one of the best
it gives u maximum performance and an amazing battary life
Though you can flash different ROMS and kernels to experiment with battery performance, most reputable ROMS like AOKP or CM10 Wong yield much difference. Too many other variables. I've heard Trinity kernel is a good one, but I just got an extended battery. I found it to be the most sure way of extending battery life.

I've tried omega Rom and phenomenal kernel but these didn't really give me any more battery.
I found the stock kernel and Rom gave me the best battery performance at around 10 hours with WiFi on and surfing internet and maybe a quick go of a game or two.

If you're really concerned about battery life, you might consider going back to an ics rom. Jb seems to be a little rougher on the battery...the only way I've been able to get closer to the drain times I had with ics under the same usage is to flash a custom kernel, underclock and undervolt, and disable all non-essential background data. PAC man/komodo is the best combo I've found, but everyone's different...
Sent from my EVO LTE
Im running Viper and run 4 pages of widget, with power saver on during the day, I get 14 - 18 hours which is amazing to me since i had the original EVO4G that was a battery whore! I had MeanBean which was slightly less life but a good rom as well.

Just ignore any ROM that turns on both cores. That leaves out mean.
You can control the cores with trickster mod from play store. Or there are custom kernels for all of or roms for this phone now which give the user alot of control along with trickster or kernel tuner to control settings of kernel

MeanRom most definitely. best battery life. Meanbean is a little more drain-ey but that's just what you get when you run JB. I just flashed irocevo's CM10.1 so I can't really comment on its battery life yet but it seems to fair well.
