Battery Life Tips? - Galaxy S III Q&A, Help & Troubleshooting

I was wondering if any of you people could be kind enough to give me some more battery tips for my new SGS3.
I'm getting around 4-5% / hour battery drain on standby. I have 2 GMail accounts on sync.
Here's what I've done:
-> Removed Kik Messenger because it was commandeering an outrageous amount of Wakelock Time (about 5-11% of Wakelock Time in 4-7 hours).
-> Installed Omega v5.0 (latest).
-> Still on Stock Kernel
-> Changed my WiFi Policy to "Only when Plugged in"

What does Facebook sync anyway? I always thought it was just once to get the contact pictures. I will disable it now

I've been using Foxhound and Siyah kernel, super combo. I can honestly say it's the best performance/battery life on any android device I've used, 6+ hours of screen on consistently - wifi/gps on, 3gmails autosyncing, autobrightness, 1hr>calls, 50+texts, light browsing, redditt, Google Music... Battery life is so subjective though depending on your apps, usage, cell signal, etc.
Experiment! All things being equal, in my experience its the kernels that make the biggest difference in significant battery life improvements, with the exception of stock roms vs. AOSP/AOKP, battery life doesn't differ very much minus bloatware in the various roms. And if you're a flashaholic like me you'll actually have to wait a few charge cycles to get an accurate representation of battery performance for your phone.

Thanks for the big post! ^v^. I am going to flash the SiyahKernel. But after turning Facebook Sync and the Wifi Policy (which I found out about today).
My battery is at 93% at 2h 01m 05s (also my battery goes down to 99% as soon as I take it off the charger). So thats 6% in 2 hours which is 3% / hour ! Getting there ^^

Apparently going to 99% immediatelly after the charger is normal for Samsung devices. So I wouldn't count that as reduction.
I dont use aftermarket kernels and roms, I have disabled a few stock programs I do not use and get a very decent battery with the 2x battery saver. I had already ordered a secondary battery which is on its way actually as well, so ill be covered from there on

99% right off the charger is a feature .
Undervolting is an option as well.

Oh my! Great feature! Do you know of a guide on how to do that, or is that just a fancy term for "underclocking" ^v^
As I am still on stock kernel I am obviously still on stock speeds but I'm going to flash SiyahKernel after I finish uploading photos of my A77

I don't think there are any OC/UV guides in the SGS3 forums but you could search XDA to acquaint yourself, there many writeups on the subject. Make sure have ADB and are familiar with it before so you can recover if necessary from any mishaps. Every processor has a different tolerance to OC/UV so there isn't a tried and true method of implementing it you just have to use trial and error.
I won't get in to it too much but undervolting and underclocking are related but different. Undervolting effectively ask the processor to run with less power from the battery at a specific clock speed or frequency. Underclocking would be reducing the overall frequency of the processor depending on the load. They can be used independently or together.

Ah thanks a-lot. Would creating a profile to limit the CPU to 300 MHz MAX during screen off save battery also?
I have SetCPU installed and have flashed to SiyahKernel now but haven't fiddled with it yet.

Download extweaks from the market instead to configure Siyah. Extweaks hasn't been optimized for the SGS3 yet but it works better than SetCPU with Siyah, it also has descriptions of what each setting does.
If you aren't a gamer you could even toggle two of the cores off, definitely will increase your battery without much if any performance hit in real usage.

terrible battery life!

Hi all, I'm new to this part of the xda forums as I had a nexus before, just got the upgrade to the Atrix, rooting,unlocking of bootloader everything went well but I just flashed Aura's from with feux kernel and im getting really really bad battery life, like I'm talking 4-5 hours. There is one process thats really confusing me, its just called "x" and its sitting there taking about 35% battery, my screen is taking 55% battery.
It's getting really annoying as my nexus used to give me about 12 hours and the only reason I moved to the atrix was to get the better battery life that I saw with all my atrix touting friends (they all had 1-2 days battery life) I'm about to flash homebase and see if that fixes it but I don't know whats going on. I have a UK MB860 and I used http://forum.xda-developers.com/showthread.php?t=1196747&highlight=t-mobile+root to root. Pleaseee can someone help!
X is the webtop and there is a fix somewhere for that (doesn't completely work). Just flash CM7 beta. Its much better than any other ROM and has the best battery life. Everything except the finger print scanner and webtop work.
Also I had really good battery on the Ying Yang ROM.

I think I might give CM7 a go you know, I loved CM on the nexus, even after it killed the memory chips it was still good! Im going to try it, is it really stable?
EDIT:
since updating to CM7 and Wiping my battery stats I have some how gained 39% battery!

Try alien, i had some battery issues with some other roms and kernels and tried alien and all is good.This phone comes with an 1930Mah battery one of the largest i've ever seen and it lasts me 12 hrs on heavy use.
battery stats
I've had great battery life on the atrix, now I'm getting a good look at the atrix on the 4800mah battery. I'm a heavy user and I could not get over 24 hours. And now I have 59 hours and I have yet to actually see how far I can take it. Cm7 beta. Juicey....
I find that all gingerbread roms have horrible battery life compared to froyo on the atrix. Cm7 battery is worse but the phone is smoother. Faux 1.3ghz kernel has even worse battery.
Regardless of the radio or magical method of resetting the battery state you use.
1:25 screen time and at 47% battery. Been off the charger for 6:15. It will make it through my 10hr shift with about 20% remaining if I'm lucky, usually I just toss it on the charger.
Background data is off, email and social apps are manual sync and wifi is off.

one weird thing I am seeing is the display which is at 0% brightness is using 91% battery
Also the better battery stats app says my actual battery is 91% but the phone is reporting 66% I wiped thenbattery stats but nothing!

I was just about to post that lol. Also make sure every time you flash a new rom you are at 100% if not that is a sure fire way to cheat yourself out of battery life. I don't know if I'm just one of "the lucky ones" but I easily get over 16+ hours with moderate usage. I'm running CM7 beta with quite a few things frozen.
Ok so I followed the guide to perfection and it didn't improve the battery life one bit! I'm trying hard to find a t-mobile radio I can flash as I have read around it could be my radio that is the culprit and I am also getting rubbish HSDPA readings, I should be getting full bars but since switching to homebase Im only getting one bar.
Using watchdog I have noticed that the Xorg process is using over 50% cpu which does not seem right to be and I believe that because its a linux process Watchdog can't kill it. Is there anyway of fixing this?
1) Uninstall Tango, Facebook and Handcent SMS if any of the three are installed. They are huge battery drainers and you can find less battery hogging substitutes
2) Freeze any unnecessary apps, I believe there is a thread somewhere in the General section that has a pretty decent freeze list (if you flash CM7, you will have very little to freeze but that's good!)
3) Keep brightness down to a minimum when you can, I've noticed kicking the brightness up rather high can be pretty demanding on your battery
4) Set SetCPU Profiles to something like this...
Screen Off 216/216
Charging 1100/216
In Call 456/216
Battery <20% 456/216
Battery <10% 216/216
5) If you have the proper kernel set the CPU govner to power saver.
6) Undervolt, test yours and never apply set on boot unless you are positive it's stable, mine are something like this...
1100 MHz -50mV
1000 MHz -50mV
912 MHz -50mV
750 MHz -50mV
608 MHz -100mV
456 MHz -150mV
216 MHz -200mV
This way when you're phone is idling with the screen off, in a call or low on battery it is undervolting heavily to save maximum amounts of battery
With this setup I can get 30+ hours pretty regularly with moderate-to-heavy usage (weekdays/non-work days), 22-25 hours with more heavy usage (work days) and close to 48 hours with little usage (weekends).
It all depends on your usage and your phone but I have found this setup here to work fairly well.
I am currently on CM7 Beta, stock CM7 radio and stock CM7 kernel, running at 1100/216 when above profile conditions aren't met. 32% been running since 9 am this morning, it is now 3:15 am, today was a long workday.
I can almost guarantee (almost) that its your rom/kernel combination. Had same problem til I changed.

fastboot erase osh
That will nuke your webtop & fix your problem.
I'm now using faux kernel for CM7 and that hasn't improved anything, in fact I think it it has made it worse. It's getting really irretating because using the watch dog app it always says there is one linux process on every rom I use that is clocking at over 50% cpu usage and It won't let me kill it (probably because it's a linux process), its really annoying me because all I want is my phone to work properly but to enjoy the full rooting experience. I know countless amounts of people with atrix's and they get a full day and a bit out of their phone with heavy usage i can't even manage 10 hours!

Watchdog eats battery like a mthrfckr, get away from that. Install BetterBatterStats instead & look for wakelocks. Which linux process are you noticing with that high cpu usage?
How many hours of screen time do you get in those 10 hrs?
Have you tried with a fastboot wipe & internal storage format prior to installing a new rom? Are you using the latest recommended radio for your phone?

Turn background syncing off if you are using that, and get in the habit of doing manual updates.
Too many times (with ANY Android device) people leave background syncing on and it tries sending/receiving data in a weak signal spot when you don't realize it. That's like a hot knife through butter on a battery.
Leave syncing off permanently if possible! That's a huge improvement right there for anyone...

That's a bit radical, no?
I'd say use Green Power so the phone can update every half hour or hour. It's a smartphone at the end of the day..

[Q] Battery issue

So, over the past few days I've been noticing a few problems with my phone, all of which have to do with the battery. After installing fauxes OC 1.3ghz kernel I noticed a drop in usages before the phone died, that's a given. So i flashed his enhanced 1ghz kernel instead, but still notice bad battery drops when im using it. It doesn't drop 40% over night or anything, only about 6%. But, if i turn the phone off and back on the % jumps up. Sometimes 20%. Is there anything wrong with the battery, or the phone?
Try calibrating the battery.
i haven't doe that since my first phone. How would i go about doing that.

Also, with faux's kernels check your CPU clocking with setCPU, or something similar. Somtimes it will lock at the max clock speed which will contribute to quick battery drain. I'm on his stock enhanced and getting close to 2 days with moderate use.
How do you get two days of battery?! Thar's intense! I haven't been able to get past the 15 or 16 hours with the stock kernel, neither with faux's stock enhanced! Do you usually drop your cpu speed while it's in your pocket or something? Or do I have a bad battery? Because I've been really concerned about this battery not lasting the monster time it is supposed to last...

I have uv and profiles set up in setCPU. I'm actually a little amazed by how good it's been since re-installing all of my mods (went back to stock recovery due to some issues).
If you're experience battery jumps then install the fix noted in the calibration instructions. Most likely you're battery isn't charging to full capacity, so that coupled with the improperly reported stats make it seem much worse than it is. The process is a bit time consuming, but it did work for me.
Little confused with my battery and SetCPU sitll

Well I have Alien #4 custom rom and it actually has the battery fix so it shows the 1% increase/decrease and I recently did a battery calibration by waiting til it got to 100% with an app that deletes the battery stats as if you would do with recovery mode. I also have CWM recovery and everything doing fine there, my kernel is now Faux's 1.3GHz but limited with SetCPU to 1GHz, and I don't know if it'll get me a better battery life just that kernel. What do you mean by uv? And I have profiles set for when the screen is off and when its charging but nothing else apart from the 1GHz setting. Is it normal that I only have 2 scaling options? Powersave and performace?
Thank you. I will be trying this tomorrow when I have the huge amount of time needed to complete this. And uv means under volt.

Thanks to you! I really appreciate it. I will be waiting for your response and maybe you could tell me if it lasts longer with the 1.3GHz ir the 1GHz. Thanks!!

System tuner: Battery life, cpu tuning, and more.

I have been messing around with system tuner app for a while now and I really like the program.
I would like to hear from people who have used this app and their results with various tweaks that this app provides.
in the boot settings menu:
1. forcing both CPU's online: this should technically give you a better battery life, since it puts less strain on on cpu at a time, has anyone had a good exprience using this?
2. Boost app loading: anyone had any significant improvement with this?
My own settings:
I usually clock my phone at 1.5 (on demand governor) even though faux's kernel allows 1.7 max. I put max clock for screen off at 384 and conservative governor.
I have Undervolted before but do not see a very significant battery difference so I just left it alone.
I tried out the autokill option of system tuner, I only tried to kill the ghost apps, to refrain from the cpu from having to keep restarting the phone, but this also seems to kill battery life...In my experience any type of task killer however detailed will reduce battery and does not increase performance, unless you're running a poorly written app that just needs to be killed.
I use three other programs to monitor my phone
1. system pannel: very good at finding rogue apps that kill cpu...I highly recommend the pro version, you can get a history of what has used cpu up to a week.
2. Onavo and My data manger which basically monitor my wifi and mobile traffic, Onavo only monitors mobile network traffic and lets you restrict apps to only wifi. however it does not measure wifi use of data. My data manager monitor both wifi and network usage but does not give you any options to do anything with the apps, it basically tells you what program is using data while on wifi and mobile.
If anyone has found a good balance between performance and battery saving, please do share.
Thank you.
I read some other guy also mentioned the all cpus on thing. im not sure but isnt it the same as making both processors work at the same time which leads to phone overheating? I will give it a try though. from what you noticed, do you like it more with both cpu on or is better the way it was?

will see then. hey seansk do you notice some kind of hesitation when trying to unlock the phone? when u press the unlock button at the top. I think that boost app loading thing causes this cuz when have it enabled the unlock button you have to press it twice to work, while when disabling that boost app loading thing all works fine...

I have widget locker and havn't had that problem...I just flashed faux's latest kernel and am in the process of re calibrating my battery, it seemed to jump from 100 to 90 in about 10 minutes!!!!!! now I noticed that happening...but I havn't had time to fully replicate it...i need more time..I believe it might have something to do with fauxes kernel, he mentioned that when screen goes off he it puts the phone into a low power consumption mode, but also has something that when you turn it on, is quick to turn on!!! we'll have to wait and see.
If you've been following this thread, just wanted make a quick update...I want to give you my results with system tuner tweaking. Forcing both cores online is a bad idea. It will literally kill your battery in a matter of a couple of hours. ICS will hopefully be different and utilize the cores how they should be, saving some battery and giving the amaze longer battery life!
On the other hand reducing reducing clock frequency on screen off will help in battery life (obviously).

yes still stock rooted, I put the governor on conservative and put the frequency to 384 or around there, while screen is off.
What helps most I found out is turning off all the radios like wifi and network data, (basically putting phone on airplane mode). Instead of dropping down 15 percent in 6 hours it drops like 3 when I turn airplane on. But like I've said before it's unrealistic I'm always recieving google talk, google voice, facebook updates and I have to have both of these on which unfortunately eats a lot of battery.
I keep switching back and forth between faux's kernel and stock and I'm actually finding stock gives me better battery life for some reason. Even though I set the clock speeds on both at 1.5 ghz.

Battery Life
Major battery drain is the screen, when on eats up all the juice, dimming helps a bit
charge source: usb vs AC charge
usb charging takes quite a while, AC charge quicker (~ an hour)
Also, from my observation, usb charged battery runs out quicker than AC charge
Data Connection, Juice defender helps a lot
turn off sync you don't need, like HTC sense

well the problem is its not my screen. It's when the phone is idle, I usually lose about 15 to 20 percent over night. if I turn off the radios it drops down to about 3 to 4 percent overnight....like I said before I can't turn off the radios...I constantly use google voice, google talk, facebook. And they require both a cell connection and a data connection. I hate to pay for more apps...I've already paid for a bunch of apps to control and see my phone's usage of cpu and battery...is the app really worth it? wish they had a lite version

I hate to pay for more apps...I've already paid for a bunch of apps to control and see my phone's usage of cpu and battery...is the app really worth it? wish they had a lite version

Juice defender is worth it (Very configurable)
If you want to know what is eating away at your battery when phone is suppose to be sleeping, the battery stat is

I have juicedefender ultimate, used it for a while actually...the only good use of it is turns off radios all other things when screen is off..all other things are negligible to battery life...I currently don't use it anymore. I tried multiple things/tweaks with it for about two weeks,...NO point lol...I want to be able to get my google talk message and my google voice texts, it annoyed the hell out of me when someone had sent something like 2 hours before and I would just get it when I woke my phone!!! I tried all kinds of things...but the only thing that actually worked was turning off radios during screen off which I don't want...I can't win lol....I can't have my cake and eat it too!!

while you sleep, you won't be checking for emails will you? but you expect to wake and see emails received.... that is where it comes in handy. with apps like tasker, you can automate some of this activities. tasker + syncer should be a good combo for you.

For what it is worth I am running BulletProof 2.3.1 and last night I took phone off charger at 10:00 PM, alarm goes off at 3:30 snoozing every 15 min until 4:15...Battery was at 100% still. It is now 7:00 AM and battery is at 96%.
This was after flashing back to BP around 8:00 PM.
I've noticed the same type of activity when in Airplane mode. Extremely low power consumption - fantastic.
Is it possible maybe to undervolt the Wifi/BT/Mobile radios? Would that make any difference or am I off base here?

You had something setup wrong then I think.. you can change how often in syncs while the screen is off, the default setting is for it to turn on data for 1 minute every 15 minutes. Most people don't need to know things so bad that they can't work with a 14 minute delay(at worst), and of couse the internet is on while screen is on, when you're actually using it.
I thought I would need to use juice defender, but since I switched to bulletproof, my usage last me an entire day. From 8am till 1am, usually with some to spare. The only tweak I made to cpu was to enable 192mhz, it isn't like there is a performance drop, but it did make a notable difference in battery life.
If I wanted to I could use juice defender to get more than one day out of it, and I keep a spare battery on me in case I really need to use the phone.. but haven't really needed it.

How many apps have you installed?

Calling All Developers

Plenty of focus on all ROMs have been performance and battery life has not been so good. Request a ROM that focuses on battery life, for those that are away from a charger during a 14 hr. work day.

Have you thought about purchasing an extended battery ?
Or
Simply limit your processor, brightness, radio connectivity, and use am android firewall to limit which apps can and can't use data/WiFi. Also ensure you have good settings in your task manager

I get 2-3 days out of my 2400mAh-battery, using MIUI and the forbidden kernel.
I can't complain at all about battery life.
Everything runs silky smooth at 192/1180mHz - xondemand
A little undervolting and a little gpu underclock.
I think poor battery life is more "user error" than something to call dev attention for.
There are plenty of guides on how to maximize battery life on the web and on xda.
2 tips from me, because many guides get it wrong or fail to mention:
- This app lets you schedule autosync. With some care and thought when setting it up, you can be always up to date without your phone snycing all the time. If you need to be in second-precise sync-though, it's not for you.
- Wifi off @ screen off is a myth. I have set my wifi to be on all time for months now and haven't noticed any decrease in battery life. If anything, it's better now.
I use mwakious, forbidden kernel at 1512 mhz and an anker 1900mah battery and get about 19-24 hours no problem
Try using Juice Defender too
I've also noticed keeping wifi connected all day is drastically less harsh on the battery than 3g.
I get awesome battery life with mentioned banned kernel and meanrom. I just switched to another rom and not sure about battery life there yet or i'd share

Battery life

I'm pretty new to the rooting scene and having a smartphone in general, so I don't know much about what's considered "good" battery life. I'm running Nil's sense 4.0 with Snuzzo's 1.2 kernel, lazy governor with SIO. My max voltage is at 1188 and my min is at 384 (I have no idea if those are the best voltages for this phone to promote longevity; they just seemed like good values so I chose them). What do you think of this battery life I got today?
Sent from my ADR6425LVW using xda app-developers app
2.5 hours of screen on time ? on a standard battery? yeah i'd say thats good
Oh, yeah, standard. I'd appreciate any input that could further increase it, if possible.

I think you mean clockspeed, not voltage.

There are two main power draws in the Rezound, neither of which you can "fix" assuming everything else is working properly.
The screen - it's power use is clearly the highest, 2.5 hours of screen time is pretty much the best you will get with a standard battery, the only way to improve it is to reduce the brightness.
The radios - it's power use is strictly governed by the signal strength received, the better the signal the lower the power use, the worse the signal the higher the power use.
There are lots of things you can do improve the battery use, none of them will make a significant difference for the screen or radio battery usage.
The Rezound is a high-end phone, it's screen and radios are impeccable... the problem is the cost is battery life. The best way to increase the battery life is to go to an extended battery.
yeah, honestly the only way to get longer battery life is to have screen on less. i mean 2.5 hours/almost 3 hrs on a standard battery is about the tops your gonna get
I used to have Neo's Adrenaline 2.0 Rom, and was getting on average 13 hours of average usage per day. I would text a bunch, Listen to music ~4 hours, and browse Reddit for another hour. I have YET to find another rom that can produce such impressive results. AOSP SCARFS down my battery life like no other. With the same usage, I get about ~8/9 hours of usage. Although Neo's Linaro roms do seem less laggy.

ineff deus. I modded a lot. removed nearly everything sense. tweaked build.prop a bit. kept apps frozen until needed. kept foreground apps low and prevented many from starting based on choice. I get nearly 7 straight hours on extended battery. close to 5 or more depending usage on standard
