I have setcpu 1400/200. I'm using the nylan kernel also....I'm running build 29....I didn't do any power saver tweaks....what else did you guys need to know?

lol 1400/200!?!? theres ur 1st problem. use voltage control instead of setcpu and stick with 1000/100 or 1100/100. i always found cfq and conservative to be nice for battery, but apparently noop/ondemand is best. maybe try both. also turn data off when not using it most importantly. also try using the auto-start manager in the ROM Toolbox app (free in market) to disable most of ur apps from staying open or updating widgets constantly in the background. freeze system apps you don't use. forget the v6 supercharger, and i'd say stick with the stock kernel. hope that helps..

Do you expect to get good gas mileage running your car at 100 MPH on side streets? Do not OC if you want good battery life.

Thanks for schooling me...lol....I'm implementing your suggestions now....What do you mean turn data off when I'm not using it? Will I still get emails, text, etc?
I'm A O K with AOKP

If you turn of 3g data, you can still send/get phone calls and texts but no email

Also, undervolt you frequencies with voltage control, I don't think you have to go to stock kernel, but do as you please I would imagine the dark blacks from voodoo control would save battery. But anyways, Marcusant had a great guide for setting up any kernel for your phone, ill try to find it..

somebody in another epic thread posted a link to another phone's thread where this guy did a REALLY thorough study about setting up kernels. he found the noop/ondemand was best on battery and that undervolting AT MOST saves about 2% battery, but typically does just about nothing. For that reason, i wouldn't bother doing it..but it's up to you. as for voodoo color you might be right about the blacker blacks..i just noticed on cm9 that the stock kernel saved more battery for me so figured it might apply on aokp too cuz its so similar

Ahem what battery life oh okay

I haven't figured out what is so different but I get much better battery life on AOKP than CM9. My imagination or is something really different on the roms? I don't use the power saver feature because I need my data all the time.

Im running Stock Build 31 on EL30 modem and no custom kernel nor am I oc/uv. I have very few apps and I have no widgets running and im getting horrible battery drain. I purchased the 1800 battery which is a few months old and I just dont know what to do. While my phone is sleeping, the battery drain hardly even moves, but when I start doing simple things like texting or checking emails I start getting drops of 2% percent or more every 5 mins of use.
Any Suggestion would be great.

(Question)(need helpp)

I'm using the setcpu app and whenever I apply a "when screen off" profile and put my phone to sleep it won't turn back on. I set it to 200-400mhz and it doesn't turn back on and I think the govenor is conservative.
I am running randomrom pheonix with genocide 2.0 kernel.
Can anyone tell me what they have their profile set as or what is a good low value I can set my phone to so that it still runs but doesn't waste too much battery life while its off. Any kind of help is appreciated.
Sent from my SPH-D700 using XDA App
Don't use profiles
I wish I could be of more assistance, but basically, I remember many of the more experienced forum members here suggesting that you do *not* use profiles with SetCPU on the Epic 4G.
I am running the Genocide 2.0 kernel on my Epic with SetCPU set to a max of 1120 and min of 100 MHz, with no profiles set and the governor set to conservative. Haven't had any issues.
Also, I use a widget called Temp+CPU PRO that dynamically shows you the clock speed of the CPU, so you can tell when it's at 100 MHz and so forth.
From what I've seen, the speed of the CPU ramps down to 100 MHz on its own when the phone is idle.
Oh.. well I have never seen that.. I heard ppl talking about setcpu is better than voltage control so I thought it was cuz of the profiles.
So about how many hours do u get out of ur phone? What rom r u using with that kernel?

There are a lot of good posts on here about maximizing your battery life. Most of it requires some functionality to be sacrificed, so it's all about your personal preferences.
Our AMOLED screens are purty, so even though I keep mine dim to save battery, once in a while, say when watching a movie on the phone, I'll crank up the brightness all the way to make the visuals pop. Do a few searches, read up, and then tweak, tweak, and tweak some more until you find that "sweet spot" that works for you.
Of course, hooking yourself up with one of those monster 3500 mAh batteries wouldn't hurt, either. Just sayin'

I know I read a lot and I do like everything they say but don't get the same result as they say and I use screen filter so my brightness is alwas reallly low
And idk how to use tweaks really well I found this battery tweak thing and I believe all it really does it change the mhz the phone runs on but I could b wrong
And I used supercharge v6but idk if it works I don't notice any changes.
So now I just changed to eh17 modem and removed all apps I don't use and only have a few. I froze the thingsi know waste battery and I don't have nothing thatuses the battery I think.. so is there any tweaks u know r good?
Make sure you freeze sns and drm services with a bloat freezer of mybackuppro's toolbox tht saves me like a couple percents of battery an hour. Also I have tried setcpu, voltage control, pimp my cpu, but my favorite overall is tegrak

I have titanium backup pro and I froze the sns, system updates, drm content, and even the google maps app and I only defrost that app when I use it.
I have set cpu set on 200-1120 mhz. And I have juice defender and its set to "extreme". I don't keep any date connection on when I'm not using it. I'm not sure what else there is to do but I'm sure I've done some more things...

Don't they cost like $70???
I wouldn't use the screen off profiles. You only would need them if your trying to have your phone never go into deep sleep for some reason. Not to say the settings would cause this, but your phone should hit deep sleep after 10 or so seconds of screen off making this setting quite useless. Also if your running genocide you need to be using on demand! You can set the throttle up % in the advanced tab of setcpu. If you wanna utilize profiles what I do is set it to throttle down the cpu as my battery dies. Saing juice for those crucial lower percentages.
Cd's or tapes?

I'm saying don't bother with the screen off profile, first of all. Secondly don't run conservative with genocide! Its geared for ondemand (unless your trying to save your battery by not overclocking at all) and ondemand is configured by going into the advanced tab and configuring the usage percantage of your cpu to switch to the next highest frequency at a certain percentage. I use 98% and I get pretty darn good battery life. I don't know if it helps or not, but I also set powersave bias on 25. Just post if I'm still confusing you.
Cd's or tapes?
No I get it now ur talking about the up threshold right?
I flashed this battery tweak and I went to check it right not the up threshold is set to 95 I guess the tweak changed it cuz I remember checking it before and everything said -1. But thanks I get it. So if I had my phone set to 200-1200mhz and ondemand and when I have a high battery level I higher the thrshold and as I lost battery I lower it...?

Battery ??

I'm down to 25% after only nine hours and I don't understand why.. Lol I'm confused for real I thought rooting would improve it. And I've only actually used the phone for probably 50 minutes. Any help or suggestions
Sent from my Dinc running cm7 with incredikernel
search around for suggestions. to start off control data usage,sync control,use auto brightness,turn toggles off you don't need uninstall or freeze apps especially those that run in background for no reason that fail to cache. use a different kernel. do some undervolting. overclock and underclock when necessary.use tasker to setup screen off/on profiles for different min/max frequency ranges and governor selection,use apps to monitor usage such as drain guard and cpu spy. check apps that hog too much unwanted usage. the list goes on. if you do your research you could save yourself 70% of battery usage. using tasker alone saved me around 30%. for example my phone is fully charged before bed,I sleep about 6-8 hours while listening to music and I have about 80% once I'm awake.nothing on besides the phone's cellular radio,no gps,no data on,no 3g,no wifi,etc. not even airplane mode so sms isn't queued all night. tasker can also auto turn off gps once gps based apps are killed so it's not always on,plenty of threads on battery saving tips,majority aren't all device specific so they're universal tips

agreed rooting won't do anything for your phone unless you put it to good use (uninstalling bloat apps, loading a custom more battery and performance efficient kernel, same with a better ROM, as well as countless performance/battery mods)
There are so many ways to improve performance and battery life on your phone with root, but you have to actually apply them to your phone.

before i flash adrenaline am i supposed to wipe anything?
Rooting doesn't improve battery life. usually a custom kernel or rom will improve battery life. It all depends what you are running in the background. With Nil's Gingersense 3.5 (2.2) and tiny's latest kernel I am getting unbelievable battery life. This is in part to how well both of these things work together along with the removal of all the bloatware. I have found that if you run Yahoo IM, it tends to kill your battery faster as well. Make sure to set most of your sync options to manual or every few hours as well. It won't impact your gmail or gtalk settings.
I understood that just rooting wouldn't change a thing. I just miss worded it lol. I was already running cm7 and incredikernel. I just hadn't realized I had 2 apps running in the background killing my battery
just flashed tinys last night and waiting to see how it works. I have two batteries and one lasts much better than the other and they have both been treated the same as far as charging and discharging....

[Q] Horrible battery life

ive tryed everything. android system is always higher than screen no matter what i flash, ics or jb. this is just getting annoying how it drops 1% every 2 minutes, when using it with data. i really like this phone but this is just killing it for me. i attached some pics of the battery and the kernel wakes. any help would be great.
thanks
WOW, that is crazy. I can only suggest Wicked V7 updated to the latest official ICS. Do a full wipe of everything and install. I have been running for 2 days and have great battery.
Good luck bro
idk what it can be I've been switching roms and ics or not android system is always higher than screen . Could it be an app or a file that's causing this?

Nope cpu spy shows how much time the phone is in different mhz.. like if you turn off your screen it will go into deepsleep and when you open the app it indicates how much time the phone has spent into deep sleep...
And OP maybe its a bad battery if you have tried ics roms and jb ?

I really like the CodenameAndroid and ParanoidAndroid roms in combination with Ktoonz kernel, I get around 2 days of battery with moderate usage and over 6 hours screen time, which IMO is great for the US S3

holy sh*t the android system is raping your battery, well I love wicked roms(ICS) awesome battery and super smooth. You can also check out FrostyICS and FrostyJB those are also really good ROM's. I personally like ICS ROM's as they are more stable and don't have minor issues that some the JB ROM's have.
Check out post #3112 and #3113 in the WickedV7 thread and check out the battery life pic people posted on that ROM.
GO to the Play store and download no-frills CPU control or set cpu and check and see what you Min and max is for your CPU.
I have an extended battery and after 4 hours i was at 65 or 70% which is way off!!! I check this and it showed that my min and max was at 1024 once I changed the min to 384 everything got better

When it comes to battery life, there are many thing that you can do to improve it.
First off, turn autobrightness off, and try and keep the brightness slider as low as comfortably possible.
Dark, if not completely black background are not only sick looking, but they help with your battery life.
Less widgets, especially ones that require frequent updates...like weather widgets, and facebook widgets will wake
your system up to update. I suggest removing most, if not all of your widgets from your home screens.
Download an app like setcpu, nstools, or voltage control to set your min and max frequencies. In setcpu, make some profiles for screen off to
make sure your system isn't throttling up while your phone is not in use.
Change your governor and i/o schedulers. With a high end device like this, you can comfortably sit on conservative governor without experiencing bad lag...i/o schedulars wont effect battery life too too much but simple ones are best (like sio).
Run v6 super charger, kickass kernalizer, and 3 script to improve the way your device runs, and battery life. Stick to wifi when possible. Having low signal will cause your phone to constantly look for a better signal which will prevent it from deep sleeping.
Use titanium backup to freeze unnecessary processes, such as DRM protected content.
Download one powerguard to help also.
Good luck!

This was mentioned in another thread. DL this app: https://play.google.com/store/apps/details?id=com.eugene373.cpu.sleep
It shuts down one of your cores when the phone isn't in use.
Also DL CPUspy. This will show you exactly how often your phone is using certain frequencies, and whether or not it's going into deep sleep.
It looks from your screenshot however that your standby battery is not the problem, it seems to shoot down when in use (at least I'm assuming that was from when you were using the device).
Click on "System" and take a screenshot so we can see what's going on
Sent from my SGH-T999 using xda app-developers app
Error is the first thing listed. Have you tested the battery by doing a full reset and flash, then not installing any apps? If this is happening across roms and builds its most likely one of your apps not playing well with the system.
Before your next flash, go into dev options and turn on Show CPU Usage. Then let us know what processes seem to stay at the top all the time.
Also get cpu spy from the market and after letting it collect its data for a while (especially when not using the phone) check it to make sure its going into deep sleep.
After those two, do your clean flash and run without installing any apps for a while. Then when you do install them, do not restore from a backup. Download them fresh from the market. Also do not restore any backed up data, at least at first.
When you do flash your system, download the full firmware to your computer (use root66 if you want to keep root). From recovery choose format data, this will wipe your internal sdcard, btw.
Now boot into download mode and using Odin, flash the firmware you just downloaded.
Once done charge back to 100% and see how it goes.
You can get the firmware from my stickied thread in development.

Good luck!

As long as you follow instructions, and make sure you have the correct fw for your model, Odin is actually quite easy to use.
Restoring apps and especially data can cause all kinds of issues when jumping between different builds and especially android versions. The updated apos and system often have different database structures, different data files, and even different storage locations sometimes.
I'm betting this is where the problem will be.
I understand not wanting to go through all that I mentioned, but if you want to know where the problem originates, you have to start removing variables to narrow it down.
If you don't care what's causing it, jump to the flash. Nandroid backup, wipe everything, odin flash, test. If all is well, restore the data part of nandroid. If problems start again then you know its either your apps or data causing the problem.
Odin instructions are in TheExels thread stickied in this section.

Battery problems

I flashed the honeycomb battery icon. I have another app that I've been using (Android booster) that is a task killer. it shows my battery life, it was right on before the new icon but now they don't match up the widget says I have 10% more life in my battery then my battery icon on my status bar. Is there any way to fix this problem? or should I just deal with it
Thank you in advance

1st off, I'd recommend dumping any "task killer" as the GN2 has this functionality built in, especially since we're talking about battery performance...
2nd, I'd concentrate more on wakelock settings, and if I had to download any app it would be those that helped manage this. This way you can force everything to sleep when your not using your phone...
Also, depending on the governor, you may need to adjust your phones clock throttling upon waking/using the device, custom may be your best bet, but there might be a "built-in" profile that works perfectly for your particular individual usage

For some reason, I seem to only be able to manage about 5 hours of screen time. I've heard of people getting 6-8 hours.
I'm using this ROM http://forum.xda-developers.com/showthread.php?t=2150145 but for some reason, that thread isn't very alive..
I tried the jedi ROM, but I just can't stand it when developers change little things about the UI. Is 5 hours normal for a ROM that's mostly stock? I'm using the UNEAK kernel.

sleepy phone. those with few wakelocks what rom and kernal you use?

I know xda doesnt like the usual rom threads. im trying to be different. my battery life is ok most days. though I notice if I idle phone the wakelocks come. and I seem to do everything in my power to prevent it. then I see people with wakelocks almost non existent. thought maybe you could share your setup. im increasingly finding myself needing the extra idle time in my phone and considering a new setup. currently using wicked v8 and ktoonsez kernal
BBS or no one can help you.
*Best Rom for wakelocks/battery* (in my opinion)

Hello,
honestly the best rom for battery life + wake locks is the Synergy Rom. This Rom is amazing! The stock kernel that it comes with is also AWESOME! You need to try this rom for yourself! As an added bonus, it comes with multiwindow enabled for all applications! As a tweak for multiwindow, it comes with sticky windows... it is like pop up video for apps.

Hit that THANKS button!
I use liquid smooth stable with bms kernel. Conservative gov with row scheduler. This set up gives me the best battery I've ever gotten out of a phone
