I have my cpu settings on 245 245 powersave when the screen is off, yet I'm still getting horrible battery. I use my phone extremely lightly, maybe once in a while to listen to music. Check my emails, chat every so often. I use to get 48 hours with light usage. Seems I cant figure what is causing my battery to drain. I have a craigslist app, I had one search enabled so I deleted that to see how much it will effect. Does google talk drain that much? In the past it was fine. My usage shows the 2 main ones are cell standby and phone idle. Any tips on finding out what exactly is draining my battery? Im running CM 7.0.2??, latest stable, forgot. Koni's was the same. I thought maybe sense drained the battery, but it doesnt seem to be the problem.
Click the link in my sig and run that battery conditioning routine for one. What kernel are you using?
And dump SetCPU. Useless app, seriously...
1. Update to the latest stable version...7.0.3.1 released this morning.
2. Google talk could be draining, but I've never used it
3. Perhaps install it under a clean install and see if that helps.
Get tge system panel app. It'll show you what apps and everything that's eating your battery. Does the kernal your on perflock unlocked for over /under clocking cause if it isn't setcpu doesn't work.

+1 SetCPU is great for Sense ROMs, but not necessary for CM based ROMs.
looks to me like you were in pretty crappy coverage. that makes the phone work hard. it's justifiable that you'll have a lot of battery drain then, even while sleeping.
you can greatly reduce this by:
1: upgrade to newest cm7
2: flash a custom kernel. may i reccomend tiamat 4.0.1?
3: put your governer on smartass, and uninstall setcpu. smartass does it better.
4: use a bsm from viperboy. they decrease voltages. work almost too well.
5: USE JUICEDEFENDER! this will save a ton of battery in low coverage, because it turns off 3g when screen is off. this still lets you get calls and texts, but with mobile data off, your battery will last much longer while sleeping.
what prl are you on?
A bit dated of a post, but most if not all still relevant. We have a lot of non-TW ROMs for this phone which sacrifice battery life for improved functionality, not by choice, but mainly because Samsung's lack of GPL compliance with regards to sharing kernel sources. Our community devs have done an incredible amount of work with their kernel forks, but Samsung's paid development teams obviously have a lot more time and incentive to work on it, and as such our community devs' graciously find even more fixes once source drops, then merge them into the community kernels we're all using. So as we wait in limbo for them to share their JB kernel contributions to our community:
Anyone that wants to add anything to the list, post to the thread and I'll keep collecting.
Workarounds for D710 battery drainers:
battery saver scripts:rmikulus found this sweet piece of development gold: if you know how to run scripts,"Die Hard Battery Calibrator" will calibrate your battery in only about 20 minutes (must be plugged in that entire time)
Probably better to use the latest and greatest here instead, much easier to install, just a simple CWM zip AIO scripts:
Jelly Bean Tweak Pack for Epic 4G Touch Fixes Various Errors
--appears to help battery life and other various issues.
Voodoo LOUDER (paid) supercurio - Project Voodoo
--not battery-related, probably causing opposite effect actually, but many find an issue with headphone audio being maxed out at lower dB than desired. I'll confirm this works on CM10 nightlies.
WiFi : Turn it off when not in use, just like anything else. Tasker does a great job of automating this process.
raise the network scan interval to reduce background wifi radio usage (Rom Toolbox allows build.prop tweaks such as this,)
change the sleep policy for the wifi to Never While Charging to allow wifi connection to die when phone is off (toggle is in the touchkey menu while viewing wifi settings.)
NOTE: WiFi is a more desirable data connection than 4G as far as batt life is concerned. 4G is auto disabled when wifi is on for most ROMs. 4G (WiMax) is a new technology that still has yet to be perfected, not unlike these latest developments in ICS.
4G Radio: Also turn off when not in use. Use the latest modems available. Note that modems won'tt install from ODIN/mODIN flashes, gotta use CWM zip installs.
Haptic Feedback: Turn off haptic feedback, vibration kills. (Particular to CM9 ROM, haptic is set too strong right now, TouchWiz-based ROMs are fine, but if you can live w/o it...)
LED notifications: Another wakelock offender. Turn them off for now, it's one of the reasons the device stays awake when it should be sleeping. Sleep is good.
Get BetterBattery Stats by chamonix : Take a look at it after a long period of uptime without restarting (quick or full) to allow a greater set of data to parse into stats. Some apps you use may be eating away at your battery from the background. Spare Parts Plus and it's root-friendly brother BladeBuddy is also valuable.
Use the latest kernels available. If you're flashing CM nightlies, you're good to go, kernel modifications are updated in the same process.
Touch sounds and screen lock sound: These still cause partial wakelocks , leading to some amount of battery drain. System Settings>Sound menu to turn these off for now. (thx coiledwire)
The CM9 Team put together a similar list with a few things not listed here. Check the 'Power Saving Options' section on the CM9 Blog
----
Android-specific:
BatteryStats.Bin This little file keeps a record of your battery usage, power amperage, etc. and every time you flash a rom, it gets wiped. The system's ability to track the exact power level of your battery is DIRECTLY dependent on this file, so if you don't allow the newly flashed system a few days to calculate averages over time, it won't really have time to realize how charged it really is. NOTE: this file has NOTHING to do with improving battery life, only calculating what the battery % shows in the statusbar (and in the battery statistics charts in the system settings menus.) I've sat at 5% battery life for an entire hour with screen on surfing the 'net. No way it was really 5% that entire time.
While wiping battery stats won't increase battery life, it will improve the calculation of the charge, if done properly. Stats are saved in /data, when a ROM is installed, initially the stats will not have much data to extrapolate from, and the battery probably isn't entirely full to begin with, therefore making a mess of a new ROM's recognition of the cell's true charge. It's best to wipe stats when your charge is above 4180mV (E4GT stock battery size.) I've seen mine as high as 4202mV. Also, if you've got aftermarket cells that aren't the same mAH rating, the results will be slightly wonky. Battery Calibration app can set a reminder to flush the battery stat counter file when the phone is charged, if you need to charge with your device on.
I notice that flashing roms with a battery @100% and charging will help in this regard, then once the system is fully booted, unplug it and drain it to 15%, then charge to 100%, then do :
Bump Charging is suggested by HTC developers to potentially DOUBLE your battery life.
Battery Tuning: We're running Lithium Ion batteries. Don't kill it to 0%. Ever. Tip: Condition your new cell phone’s battery to make it last longer (but be sure to condition it properly)
Live Wallpapers and other background services: If you can live without them, turn off the services. Many common apps trigger network connections on a periodic schedule, further causing drain. increase sync periods, or just sync manually.
Sync: Yet another form of background services. If your sync is running all the time from frequent emails, gvoice msgs. etc... and the like, try turning off some of your heavier data tranx and refreshing manually when you need it.
Again, please tack on posts for this thread if you have good additions to make, I'm just trying to collect a one-stop shop of battery life savers, and a place to point newbs when they start trainwrecking dev threads with questions about it. This is my humble way of giving back cuz I was one at one point.
Thanks, some of these tips most users may know but the one that helpped me was the notification light when running cm9! I worked 10 hours a day and cant use my phone but my battery was draining like crazy! Much better!
Solid advice. I do everything mentioned here. I also throw in a bump charge to finish it off..old habits die hard

Well, its just my routine. I charge to full, power down charge to full, unplug, power on, plug back in. When. I open Battery Calibration app, if battery shows 100% but only like 4110mV instead of 4180mV+ I will unplug and plug back in a minute later then wipe stats when it shows anything over 4175mV and 100% charge...confusing enough?!

Thanks For the Guide.
I was really dissapointed with ICS.
I was still running EL29- Rooted and was running everyday on 14hrs with Wi-Fi always on. so after seeing that most bugs were fixed on FD24 i updated and yesterday i was running on 5hrs tops with Wi-Fi on.
So i did some suggested tweaks.
Wi-Fi off.( only ON when i need it)
GPS- I unchecked the last to option on the location.
Adjust haptic
uncheck some Sync from Google.
by the way what's? "Internet Sync"
and now.... im at 66% after 7hrs of being unplugged.
Internet sync meaning anything that may transfer data in the background like google talk, weather apps, Skype, etc.
Glad to hear those stats ! Take a screen Cap of the battery stats when it gets below 10% and post here

We're currently in a lull period between development phases now that ICS is blowing up all of our E4GT's. Samsung's kernels leave a lot to be desired, hence the current work towards a proper aftermarket kernel. ICS roms are very new, especially the custom ones going on in the dev kitchen right now. Software level ROM coding is one thing, the devs will get that fixed, but ultimately they're dependent on a solid kernel... and one of the biggest problems with the kernel, is that ever-elusive battery life.
so:
God-Tier devs, correct me if I'm wrong, and please add your thoughts, additions, and suggestions below. I'll try to keep a live OP post for a universal E4GT battery tweak guide.
Things that eat up our E4GT battery for now, with workarounds:
WiFi : Turn it off when not in use
raise the network scan interval (Rom Toolbox allows build.prop tweaks such as this,)
change the sleep policy for the wifi to Never While Charging to allow wifi connection to die when phone is off (in spare parts).
NOTE: WiFi is a more desirable data connection than 4G as far as batt life is concerned. 4G is auto disabled when wifi is on for most ROMs.
4G: Also turn off when not in use. Use the latest modems available. Flash with odin/mobileOdin because the CWM flashables sometimes don't stick.
Haptic Feedback: Turn off haptic feedback, vibration kills. (Particular to CM9 ROM, haptic is set too strong right now, TouchWiz-based ROMs are fine, but if you can live w/o it...)

Suggestion, with disclaimer: Use the latest stock or Rogue kernels and modems. sfhub keeps the most updated modem D/L list . Don't forget that you should not flash ANYTHING from ICS kernel/recoveries yet!!! There are known issues with these kernels, and every last one of them is a beta stage leak from samsung along with a custom recovery and some little tweaks to work with the various ICS roms. The flashing HAS bricked MANY phones! There will be great fanfare and notices from the developer teams once we have an ICS kernel that works. It's mostly dependent on Samsung releasing sourcecode, although there are some teams working on porting the source of the other Galaxy II's... the race is on!
Touch sounds and screen lock sound: These currently cause partial wakelocks in Galaxy S2 ICS ROMs , leading to some amount of battery drain. System Settings>Sound menu to turn these off for now. (thx coiledwire)

Universally true:
Live Wallpapers: If you can live without electricsheep or the other various animated wallpapers, do so. I can't
Battery Tuning: If you didn't condition your battery when you first got it, good luck. In any event, try to condition it from here on out by burning it out completely (phone won't boot with it) then charge 100%, keep it off charge until it dies again, CWM Wipe Battery Stats, run the battery down again without charge. Repeat the charge/kill cycle a couple times. New kernel or ROM? Start from scratch again. Battery stats are saved in /data, so old stats can mess with a new ROM's recognition of the cell's true charge. Also, if you've got aftermarket cells that aren't the same mAH, you'll only get as good a conditioning as the weakest battery can take. Battery Calibration app can set a reminder to flush the battery stat counter file when the phone is charged, if you need to charge with your device on.
Sync: If your sync is running all the time from frequent emails, gvoice msgs. etc... and the like, try turning off some of your heavier data tranx and refreshing manually when you need it.

Darchstar and the CM9 Team put together a similar list with a few things not listed above. Check the 'Power Saving Options' section on the [url="http://e4gtcm.blogspot.com/p/customization-guide.html] CM9 Blog[/url]
I've also since learned that wiping battery stats does nothing with prolonging battery life. There's numerous articles quoting official Google/Android developers where they explain this flat out It may help your system recognize the true percentage of your charge, but that's about it.

Good thread, thanks for the tips.

Agree with just about everything. One thing that I disagree with is letting your battery die at all. It actually decreases the life of the battery in lithium ion batteries. Its an old school method for old batteries. Try never going under 15% if possible. Everything else is correct as far as I can tell.

On the topic of battery calibration, if you know how to run scripts, the creator of V6 Supercharger and 3G Turbocharger scripts has also created "Die Hard Battery Calibrator" which will calibrate your battery in only about 20 minutes (must be plugged in that entire time)

Hey, I'm trying to fix my battery drain during light use. Having screen on for not even 5 minutes eats around 2% of my battery. I've calibrated, gone through many different ROMs [GB(CM7,MIUI,Sense) and ICS] with full wipes(format and wipe). leading to my question in hand... how do I completely wipe my phone? I visit the wifi settings and see a wifi history that were from a pretty long time ago(before wipes). This leaves me thinking I have not fully wiped my phone in between flashing. Does the google account save wifi history or something? Thanks for any tips!
My problem still persists any help is appreciated
Sent from my Inspire 4G using XDA
You seem to be wiping your phone correctly. The WiFi settings are backed up under the Google account and are restored when you add the account again. It also backs up other settings, wallpaper, and app data of certain apps. Here's an easy way to fully wipe your phone (including the SD card app files in .android_secure) - http://tinyurl.com/66fc8og
It's called super wipe script and it is from the Android Revolution HD ROM thread, thanks to mike1986.
Sometimes the battery loses it's ability to hold charge after sometime. This happens when the battery is quite old or due to various reasons that I don't know. You'll need to get a new battery then.
On the ROM side, a good ROM+kernel combo gives the best battery life. Instead of using a plethora of apps to save battery, finding the right ROM & kernel combo and choosing a good CPU governor and min-max frequency settings will give you much less battery drain. I don't use any battery saving apps, but I run a great ROM (CM7.2 RC1) with an awesome kernel (LorDModUE 8.9b7), with smartassv2 governor running 122-1152 Mhz and a few build.prop tweaks.
You can try out my combo and see if you're getting any better battery life. The max I've gotten recently is 14 hours of heavy use with 4 hours of screen on time, wifi on for 75% of the time and a lot of web browsing and video watching. I usually keep my phone in 2G mode and only change to 3G when I need to use the internet. 3G drains the battery really fast. On average I get around 13 hours heavy use, 1 day medium use and more than a day of light use (with mobile data off unless when necessary). I get around 1% per hour drain in standby.
You can try this ROM VictoryMod by victoryo. It has my same ROM+kernel combo I've mentioned before + build.prop tweaks. Change the CPU governor to smartassv2 with 122-1152 Mhz frequency. It gives great battery life.
Among the Sense ROMs, Android Revolution HD with klquicksall's kernel and LeeDrOiD HD with LeeDrOiD's kernel give awesome battery life.
Thanks for the reply! I greatly appreciate it. As for my ROM, I've been using the latest LeeDroid, but the battery drain seems to be happening across all the ROMs I've tried recently. I never install battery saving apps, and I keep default kernels and settings. The problem is probably with my battery, I've had this phone since last May, so almost a year. I'll see if I can get this problem sorted out. Thanks again!
i am running cm9 alpha 4 with kernel fe16 and i cant get through 5 hours without having to charge or throwing my extended battery in. i need my phone to last the day with the job that i do email,calls,text,social networks,ect. i would really like to know why my battery is draining so fast. i deleted alot of apps that were draining the battery, but it dies too fast still. please help.

Solid black background and lockscreen, inverted apps and dark settings. Ditch facebook twitter and crap like that that updates and burns battery.

Go outside and play instead of sitting on your phone youtube'in
Whatever guys that stuff applies to any mobile device. Turn off stuff you arent using, ditch the live wallpapers, worthless apps, and status updates and you get more battery life. You want to surf, download, stream then by all means toggle wifi or 4g on but no reason to leave it on while you are doing nothing. Same goes with gps and bluetooth.

With the exact same setup I have now, I get 20-30 hours on gingerbread. On cm9... I get five.
I don't leave wifi on. Don't leave 4G on. Usually have a minimal screen on time of around thirty freaking minutes.
Don't tell me that I need to cripple my phone (i use it for business). Because there is something clearly wrong. I suspect it is the kernel. I don't have unnecessary apps installed (aside from ones that work great with gb). Don't use a live wallpaper. I do however, refuse to disable auto syncing.
There is clearly an issue with ICS.
I'm not going to turn my smartphone into a paperweight like you suggest.

Not using stuff you don't need is hardly crippling your phone its smart use. I never said anything about turning off auto sync either but you should be selective what you sync. Google plus, drive, picasa all sync pics and other crap in the background without telling you and it kills your battery especially if you are in a bad signal area. Figure out whats draining your battery by using better battery stats and apps like system panel lite http://forum.xda-developers.com/showthread.php?t=1179809
Honestly though try another rom and do a clean install. If you get 80% less battery life no amount of tweaks will fix it and the ics leaks are good now. Several months ago the battery life was half of gb and now they are about the same.

Trust me, I've done all this. I have the same battery life with ICS now that I did a couple months ago. Going to stock, it is wonderful. Had my battery tested by sprint yesterday, it's fine. So, i'm just waiting for a real kernel and hoping for the best.

Turn off LED notifications they're a known issue for wake-lock.
I get terrible battery life on alpha 5. Change to a stock kernel might help.
Kobridge's tweaks http://forum.xda-developers.com/showthread.php?t=1668853 along with Badass Battery and CPU Spy have helped me trace battery drainers. Also wholeheartedly agree turning off apk's and functions that are of specious value helps greatly ie.( auto rotate, auto brightness, dialing back on sync; etc.)
Good luck
I just rooted my phone and installed CM10a couple days ago. I love jelly bean and having my phone debloated.
My question is.... are there any roms or settings on the roms that can help me get get better battery life? The battery life on my gs3 is good but not great... I selected the powersave feature on the CPU governor, turned down my brightness, turned off gps and bluetooth. I have been thinking about installing juice defender but I have had it previously and got tired of turning it off when I streamed pandora.
I am a pretty heavy user... about 1-3 hours of screen time per charge. I have seen some pretty rediculous stats out there and would like to be able to achieve a full 24 hours. :fingers-crossed:
I had my gs2 rooted and it seemed to get better battery life than the gs3 (rooted vs rooted). There was no comparison when it came to stock vs. stock.
Any tips or suggestions would be greatly appreciated! Thanks!

Could you please elaborate how I should go about switching to that setup from kernal version 3.0.42 and the nightly CM10?
I have also had problems figuring out how to properly backup with nandroid or titanium. I can never get the backups to load
I am ready to try pretty much anything to try and get some premium battery life and performance.
I really appreciate your help and input. THANKS! :good:
Basically ya download the up to date versions of the aokp ROM and the KT kernel for aosp jb. Then ya open to recovery and first go to backup/restore and make your nandroid. You can decide whether or not you want it on internal SD or external. Once that's done ya wipe your system & caches like ya did for cm10. Then flash the ROM. After the ROM then flash gapps & fix permissions and reboot. Let the ROM settle and then boot to recovery, clear cache again and flash kernel then reboot. My instructions are a broad guideline though. I'd make sure to fully read both the aokp & kernel OP'S to get a warm and fuzzy on what your doing

seems like you are new at this so let me add a new thing, the S3 has amazing battery currently 9 hours up time and 1.5h screen on time and still 50% left and that is very light usage. Usually I listen to music play games watch movies and after 12 hours i still have about 10% left.
For starters cycle the battery a few time. Charge 100% and let it die 0% not charging in between, take out the battery and put it back in. Let it charge to 100% and and do this a another 2 times during a week. This will will use all the cells in the battery and should give you a boost. I have herd following above but charging while off may help, but cant confirm.
The next thing to do is remove bloatware or app you will never use, some of these apps will just load up in memory and use up your battery. Most apps can be disabled in Settings > Application Manager > All. Things like Allshare Play can be disabled, some apps like video hub may have gotten an update that needs to be removed before it can be disabled, this is the same as freezing in Titanium Backup. BE CAREFUL WHAT YOU DISABLE BECAUSE THERE MAYBE NEGATIVE EFFECTS.
This is what I have done and my battery has been amazing and never use power saving mode, actually i took it a step further and downloaded system tuner and disabled non essential apps like Vplayer from even booting at start-up.
Flashing different kernals and ROM can greatly improve battery life but you loose OTA and forced to wipe which i got tried of doing so i stick with stock. Waiting for CM10 to go stable then i will switch. The S3 stock is still snappy and never lags and for me battery life is very good.
thank you both very much. I just installed the AOKP rom and I will try the power cycles next time my battery dies. One question on the AOKP... I cannot figure out how to change or add lockscreen icons. and yes I have looked at the lockscreen option on ROM control. I can post screenshots if you dont believe me lol

I cannot figure out how to change or add lockscreen icons. and yes I have looked at the lockscreen option on ROM control. I can post screenshots if you dont believe me lol

We believe you because those lock screen options haven't been implimented in the ROM yet. If its a must have for you I'm pretty sure ktoonzes aosp jellybean kernel will work with CM10.

Lol well that explains a lot. Its not a must have but it would be nice. Hopefully they implement it soon.
Thanks everyone!
One other question. My network constantly switches from 4g to HSPA to 3g. When my phone was stock it would stay on 4g (lte) 99.9 %.. is this normal? I would prefer it to stay on 4g. I also think it might hurt battery life since its constantly switching even though lte is a battery hog.

What rom are you on? I'd love mine to switch to 3g the majority of the time, LTE is such a hog, there's no way that switching it down is going to use more battery than staying on LTE full-time.
