[Q] CPU/Governor/IO settings to get best battery life - T-Mobile, Samsung Galaxy SIII

I have a T-mo SG3 currently running AOSP LIquid smooth rom/Lean Kernal v1.9. I consider myself a very light user, light texting light internet use during the day and want to get the most out of my battery. What governor is the best to use, where should I have my cpu/voltage settings, etc. Is the Lean kernal the best for this rom? Any help would be greatly appreciated, thanks in advance.

im running CM10 and my setting are NOOP and ONDEMAND, last me around 20hrs with display on time around 4hrs some.

I am on LiquidSmooth and using Interactive/Deadline and am getting great life. I am using Lean Kernel 1.6. I've tried 1.7,1.8 both regular and exp versions and had problems with the cores not shutting down as they should on both. An SODs on 1.8 almost daily. I've already downloaded 1.9exp and am going to flash it but i have to keep deleting all these Update threads. jk.
Also check out the second post in my battery thread. Has a huge portion about Governors and Schedulers explained.

Lean kernel vs Franco kernel

Which one do u perfer guys ? Both are awesone and cant make a decision Battery life ? Hotplug efficiency? Performance ?

I'm getting crazy good battery life and performance on lean kernel and AOKP. Franco is good too, but I think I'm getting much better battery life on lean.
Each phone is different find out your preference on your own

James Bond kernel.
I've seen what franco has done with the nexus s kernel, realiable, smooth, and constant updates, it was always my choice. So as soon as i get my GN its the first kernel i'm going to flash and hopefully it won't ever disappoint
same for me. I have a freaking good battery life on lean but better performance with Franco

I've tried both for a great while. Battery life with interactivex on lean and hotplug on franco lean is definitely better, on my phone Lean runs a little bit better. on my phone.

its Imoseyon kernel on Rootzwiki. btw, Ive tried both Lean and Franco kernel, I still prefer Ezekeel Glados kernel though. amazing smooth and friendly battery life.
I was using franco's kernel, but with all the hourly updates lately, it spooked me a little, so now Im on trinity inferno512 kernel, and wow games run fluid with the GPU at 512mhz.
im still debating... im jumping back and forth but i need to stick to one for a week and try it out!
leankernel has updates just as much as franco... i say thats a good thing
i say take a week long test and run some benchmarks with each of those kernels, take a screenshot, and come back with what you like.
Im working on that now.
GLaDOS is by far the best kernel for my phone. No lags whatsoever and four hours of screen on time with the stock battery
I'm starting to lean toward glados myself. I've had a lot of issues with Franco's 14.x kernels.
I've also found lean kernel to be a bit choppy. Shadow gun runs really choppy w lean kernel, but ultra smooth w either Franco and glados. It could be that I'm not using the correct governor though.
I have tried both back and forth. AS of last update I've tried franco 14.4 (deep sleep ~50%) which is good but has a much better battery life (deep sleep at 91%) on hotplug of lean 1.8.0.
+1 for lean
I have used lean kernel for a while now. I used to get lots of lock screen lag with Franco. Which I don't with lean.

Im on Leankernel 1.7.3 right now. Used Francos way before, but after Version 13.1 i started to get battery drain issues. So i switched over to Glados which seemed to have a good battery life to me, but was very choppy overall on Wheatley Gov'.
Lean is the best for me at the moment, almost 4 Hours Screen on time isnt a problem for me, i use the build in InteractiveX Governour, with some heavy undervolting. Data, Sync, Wifi , ... everything enabled. Screen Brightness ~ 35%
I gonna try Lean 1.8.0 Later that day. But i have to admit that Franco's next upcoming with Turtle Governor might be an interessting choice either.
For me, both devs are doing a really great job, both Kernels are good.
I've used three different Franco kernels and had freezing and reboot issues with all three of them. Never had an issue with Lean Kernel.
I don't care what kernel I have. If:
1.At the end of the day on my normal usage phone has less than 60% of battery left it means that the next day I won't manage
2. I have less than 60% I have to recharge overnight
3. Phone can get me throughout the day on heavy usage ...
Don't need any fancy kernels if they don't tick the first box
Edit:
Just tried lean kernel and its way to slow. Scrolling in text app or anywhere really isn't even half as smooth as Franco ....

After trying many kernels... I always come back to Faux123's kernel (Currently 011b10u). It's just such great battery life... idle battery drain is just a horizontal line on the battery graph for hours. LOVE IT. (P.S. Ultra-liquid-smoothness too). http://rootzwiki.com/topic/12512-kernelgn-lte3017ics4023uvgpucpu-occifsslqbotgfiopsv010jan-17/page__st__930

[Q] what is the best battery saving kernel?

hey guys, i am looking for a kernel that will save me on battery. i am running zombie 4 rom. it says it runs the dark x kernel. i don't need to be running at super speeds but i don't want screen freezes either. i just want to be able to play my satellite radio without the phone draining 3 percent every 5 min or so. any help would be great.

I would be interested in this as well. Currently I am Rooted and have tried a few ROM's but haven't found one yet that doesn't have some bug or another. {Granted, I haven't tried them all} Tried one ROM that really distorted my custom made Wallpapers, which is a big deal to me. So... yes, any info on a better battery life Kernel would be welcome.
Currently I am not a "heavy user" on the phone. Talk - Text - You Tube occasionally... that's it. Constantly looking for better ways to improve this already amazing phone.
Eugenes kernel has given me great battery life. Either get down with Eugene's Macnut ROM which already has it or search for it under the general section under the bounty thread for Eugene. Its in page....58?
Keep in mind that the "beta" kernel does not have bln support but works just fine so long as you use the lionheart governor.
If you can't find the bounty thread then I'm sorry for you.
Synergy kernel has been awesome on battery for many.

I also undervolt via system tuner pro so that I'm at 1137 at 1.51

How you use your phone determines the best way to get the best battery life. Basically there are two ways to save battery: cutting power when not in use and delivering less power to the processors.
If you use your phone intermittently throughout the day for texts or calls, you'll get the best battery results from kernels/ROMs/apps that cut unnecessary functions when you're not using the phone. For example, juice defender cuts your wifi and mobile data when your screen is off and reactivates it every 15min (can be configured otherwise) to check for notifications. Darkside's Digital Warfare utilizes something called "deep sleep" which actually completely turns off your processors when the screen is off, but keeps the basic cell radio on so if you receive a text/phone call it will wake up the processor. These functions have the largest and safest impact on battery life.
If you're constantly using your phone and you want better battery life, you basically only have one option: undervolting. This is essentially supplying less power to your processors, which can be done through system tuner. It's not a free ticket, however; if you undervolt too low then at higher frequencies (playing games, etc.) your processor will become unstable and your phone will randomly reboot. If you encounter this, then don't undervolt that much and up the voltage to the last safe level. Just for reference, undervolting by 50mV is usually considered safe and undervolting past 100mV usually results in boot loops. But how far you can actually undervolt depends on your individual phone hardware, there's no universal answer. Make sure to not set your undervolt settings to set at boot until you find a stable voltage. Otherwise, you'll be forced to restore a nandroid if you encounter a bootloop.
TL;DR
If your phone already lasts a day and you want it to last 2-3 days, look into ROMs/kernels/apps that cut unnecessary functions when not in use. Most effective way to extend battery.
If your phone lasts 8 hours and you want it to last a day because you're a heavy user, look into undervolting with system tuner.

[Q] Kernel that has best battery and performance?

Ive tried a few and they alll seem to be fairly decent. I woud like one that has good battery life and good performance when I need it. I also wanted it to be stable and have no random restarts or dropped signals.
I would like to know what you think is the best kernel for me that gives me these; I dont need any of the extra features, just good battery life and performance.
THanks in advance.
I've tried different ones and the best one that works for me is the franco.kernel and Eclipse rom. Simple yet great on battery live.
If it helps, I'm using GSM Liquid Smooth ROM. The ROM came with the latest Franco nightly but it doesn't seem as good on battery life as MS4 was. Is there a huge difference between wheatley and interactive?
Sent from my Galaxy Nexus using xda app-developers app
Yes. Wheatley lets your phone idle when you are using it for less intensive tasks.
Also, There is no best rom or kernel. No one but YOU can determine what is best for YOUR usage and YOUR device.. Just try them all.

But wheatley seems.. not finished, to say the least.
I have an acceptable battery time with the latest GLaDOS kernel, with standard clock frequencies and using interactive as governor. That governor seriously has never failed me.

[Q] Best HOX kernel for battery life (smooth ui no gaming)

What is the best kernel for getting the best battery life? I have tried many and the most screen time I am able to achieve is 3-4 hours. This is better than most users but I am sure that getting 5 hours could be done with a kernel that has proper power savings. The phone is overpowered and ramps up its cpu for simple tasks like sending whatsapps. Also is there a kernel/rom combo for achieving the best battery life that work great together? So far the best for me was the Renovate 3.0 rom running a stock kernel reaching 4 hours of screen time. I am currently running maXimus 2.2 with faux 006m and getting around 3 and a half hours of screen time.
Thanks,

Yes and even purchased his app to see if turning off cores and under clocking would help. His kernel has some serious wifi issues so I could not keep it. But also the cores would turn on even when they are set not to. Seems that it is not perfected yet.

i diint want to open a new thread neither i want to hijack this thread. my questions is somewhat similar to the opening post with only few changes. i like to play games in this awesome screen. i use wifi for an hour or so. i need 12 hrs of battery life with around 30mins of light gaming (temple run/stick cricket/fruit ninja etc) what romand kernel should i use which would give me optimum battery life? currently i am on ARHD8.1 with stock kernel.
Try n3ocort3x's kernels. He's developing his kernels for the most battery life without compromising the ui smoothness and performance. Does pretty well on sticking your custom underclocked values and does a great job on undervolting.

Need help with a Gingerbread rom

Hey guys, when i started using the epic touch which was pretty recent, I jumped straight in to the 4.x toms. Currently on blu kuban. Now I really want to go to the best possible gingerbread rom for battery life. I have no idea which rom would have the best battery but I am extremely frustrated with my battery drain on ICS. Can anyone please give me their opinions from what they remember from the gingerbread days or if there is any other way i can drastically improve battery life on ics either with a different rom or kernel? Thanks.
On GB the popular roms I remember were Caulk's and Blazer but I had a stock rooted EL29 setup that I stripped down myself and used QQ Launcher on and really enjoyed for a while. Honestly though battery life is really about the same for me on ICS and GB. I'm currently running agats rom but wicked sensations, aokp, and black rom are all pretty similar in battery life. I'm also now undervolted by -.50 and that has helped even more.
Honestly though its really just a matter of managing your phone and knowing what is running and burning up battery in the background. Use dark themed apps, turn off wifi and 4g when not in use etc.. I also use data enabler widget and turn off data at night now then just toggle back on when i wake up. Last night I dropped 2% in 6 hours.

thanks man, so a noob question now. I never undervolted. I just switched to Universe v2.0 rom which now uses kuban kernel as well. what does undervolting do and how can I help?

Undervolting is supplying less mV to your CPUs. In terms you can extend you battery life as the phone can operate at the same speed using less voltage. (Less power used, more battery available)
With that said, don't under volt too much usually -25mV to -50mV is optimal if you go any less you run into the issue of nit having enough voltage and your phone could freeze or crash. Both agat's and kuban kernels offer undervolting and under clocking.
Just a FYI I'm using sleshepic's the governors kernel. No undervolting, just have it set to CFQ and Pegasusq at 1000 Max and 200 min and I've been getting around 11 - 12 hrs with moderate use.

Yes voltage control on kuban kernel allows you to under volt. If you click on each step(slide the voltage to the left) you can under volt it. Then apply settings and your good to go. PM me or reply here is you have any more questions.

Voltage and governor control is now built into Kuban ROM. It's all in extweaks in the system menu. You may want to try it out. You will be losing a lot going back to gingerbread. I actually get better battery life on Kuban than I ever did on GB. And I haven't even messed with under volting. I do recommend the Wheatley and Skywalker governors for the perfect balance of performance and efficiency.
Kuban has been good for me as well.. I don't under volt at all.. To unstable on my phone.. I get 4 hours screen on(heavy use) and good deep sleep with the Kuban kernel(1100-200), placebo tweaks, odexed a few apps, and a modified framework to make it more zippy without compromising battery
