Which rom has the longest battery life? - Samsung Epic 4G Touch

The longest I've experienced was with stock gingerbread but it was way to inconsistent. I'm running cm10 now and I get just over 2 hours of screen time with auto brightness on.
Sent from my SPH-D710 using xda app-developers app

I use PhantomHacker's gingerbread Blazer rom. Then I use Tegrak from the Play Store to underclock my phone to 200mhz to 500mhz and also undervolt 50mv. i usually get around 4-5 hours screen time.

Setcpu Settings For battery

Anybody have a good setup for the Best battery results? I.e. profile setup and CPU speed. I'm using beastmod!!! Also any exp. With juicedefender?? Seen a guy had setcpu and juicedefender running at the same time with good results. Thanks!!

Use juggs .03 kernel set to 1500 max 384 min and on demand ... Great battery life and decent speed u can always bump it up some
Edit : i never have used juice defender although as u said i see ppl use it all the time... On beastmod 3.5 with jugs i was getting over a day use with what i consider normal usage

Thanks, I will try juggs..

How to solve battery drain problem in Ics Beta

Hi guys. Im using Ics beta with Ka11 rom. But battery drains fast. How can i solve this problem ??

Helps if u put what kernel your using? I think some still don't have deep sleep... mine hasn't I'm on doom kernel with oc
Sent from my R800i using XDA
charge to 100% then go to cwm and wipe battery stats
There is some info I saw saying underclocking whilst screen off helps, but be careful because if you get it wrong your screen won't come back on.

Wifi is stopping deep sleep afaik. Switch off wifi when you're not using it
i use doomkernel v11 oc to 1.2ghz. and im not use my play for call just gaming and internet.off the wifi and on the plane mode and set profie in setcpu when screen off set to powersave governor.i left it at night and the battery still at the same % in the morning.
hmm. i want undervolting but i cant do that. how can i do that. which settings ? and, what's the best Cpu governor. I dont know what is ondemand, powersave etc. And i set CPU Profile to Min 134 Max 806. And rom is still Smooth. my wifi is closing but still battery drains fast.

For undervolting try IncrediControl. Best CPU governor? Depends on you but personally I like smartass v2 . BTW I'm using KA11 ICS Rom with DooMKernel and my battery life is quite good
The way to get best battery life on ICS Beta is to install DooMLoRDs Advanced Stock kernel. This has fully working deep sleep, as it uses the stock Sony kernel, but also has CWM, root etc.
That's the only kernel I recommend at the moment, until we get the newer kernel sources.
Also use SetCPU or some other app to underclock when your screen is off.

When not on wifi its like im not using any battery at all (maybe max is -1% battery level per hour.
I am overclocked at 1.4ghz max and min is 576mhz (ondemand governor) and I use Sytem Tuner (the best all in one system tweaker for me ). I set my screen off behavior to 921mhz conservative governor (this will underclock my phone while im not using it). My read/write cache is 6144mb. I use Juicedefender and set it to advanced mode and let it underclock my phone when idle as well. Im using .62 firmware and JokaWild Rom v2.5 with Xperia S Package. My kernel is Doomlord's kernel v11 and I do not have any battery issues. I always have a good and not corrupted nandroid backup as well as Titanium backup in case my phone gets crazy.

Awake time.....

I am running stock ICS, with the cpu sleeper app running and my "awake" time is crazy high. I use to have awesome battery life pre ICS, oh and I forgot to mention that I have the nexus extended battery what is running and how can I kill it....I use to get around 19 to 25+ hours before zero now I don't. I have tried to celebrate the battery by letting it run to zero, wiping battery stats and having it charge up to 100% powered off and it still suck. What am I doing wrong? Also I enclosed a pic of my current battery stats for all to see

I suggest getting GSam battery monitor and seeing what is killing your battery. If you really want improvement root that bad boy and gets your self a custom ROM!
Here is my battery life, typical day. AOKP 7/15 with latest CPU sleeper.
Sent from the pink Unicorn from the Darkside.
Have you looked through the battery stats list of what been running to try and track it down that way? I've also hers people say if your using google voice and restored it from a backup that it will cause wake lock. Uninstall and reinstall from the market if that's the case.

I am using gsam battery and it says that 26.5% (which is the highest) is used by the "android system" everything else is below 5%....and I am rooted as well......my task manager also says the same thing

im having the same problem with no luck. everything i try has failed. heres an example:
It gets worse sometimes. Google Service seems to be the reason.

Ok I acquired setcpu from the market and I was going through the forum and about of people say that they use the "badass" profile with "noop" what it's that and what are the settings since they (badass) are not included

Also try out CPU Sleeper: http://forum.xda-developers.com/showthread.php?t=1745516
This is also hosted in google play.
Description of the badass governor:
Badass removes all of this "fast peaking" to the max frequency. On a typical system the cpu won't go above 918Mhz and therefore stay cool and will use less power. To trigger a frequency increase, the system must run a bit @ 918Mhz with high load, then the frequency is bumped to 1188Mhz. If that is still not enough the governor gives you full throttle. (this transition should not take longer than 2-5 seconds, depending on the load your system is experiencing)
Badass will also take the gpu load into consideration. If the gpu is moderately busy it will bypass the above check and clock the cpu with 1188Mhz. If the gpu is crushed under load, badass will lift the restrictions to the cpu.

Problem with Cm 10.1

I have flashed cm10. 1 on my n7100 and the volume is lower than i used to in the stock rom and it consume more battery any help with that
Sent from my GT-N7100 using xda app-developers app
I don't think there's much you can do with regards to battery life. I've tried doing what I could to get a good battery life with CM/aosp and the best I could get was 5.5hours screen on time on lowest brightness and 12hours between charges. Compared to stock I get 7-8hours screen time and 24+hours between each charge. There's nothing much you can do with battery life.

You could flash a kernel like n.e.a.k kernel .. and download their app..
For getting a slightly better battery life, undervolt your CPU by 50-75 mV each step and you also may set the CPU ti 1.4Ghz instead of 1.6GHz
For the sound, using their app, there is an option for speakers and headphones.
Set speaker between 57 and 63(loudest) and same thing for headphones. .

Dsp manger is their app am i right cause if so i can't find that option you talked about

Even with neak kernel or redpill undervolted it still sucks at battery performance. And sometimes under clocking to 1400mhz results in graphic glitches in the UI with aosp. I think its just not designed to manage battery usage as effectively as Stock ROMs.

The problem isn't in Google .. 4.2.2 works with great battery on nexus 4 .. cm can't be like google but they are trying to make the rom as battery efficient as possible
I personally get 5-6 hours of screen time..
I get 6-8 hours on touchwiz.
No big optimizations made.. 1600 MHz and UV 50-75 .. and overclocked GPU for better rendering without UI glitches ..
Sent from my GT-N7100
Of course 4.2.2 is compatible with good battery life.
Here is attached the proof

What's better to use? SetCPU or Stweaks?

Basically I'm trying to lengthen battery life by keeping the cpu in a weak state while the screen is off.
But it almost feels like since I installed SetCPU by battery life decreased?
The only profile I have active is for the cpu to slow down to 500 when screen is off. But Stweaks came with my rom I have installed.
What shall I do?
