I've seen so many threads here and at The Verge that I just don't understand. I've been using Android devices now for about two years and I've NEVER had a problem with battery life being worse than my iPhones. I have a 3GS and the battery on it dies after about 8-10 hours of moderate use. Meanwhile, I'm at 12 hours on my SGS3 and 50% battery. I also have quite a lot of applications running in the background. Granted, today I have been low usage, but yesterday I was on the phone for hours and I still went 12 hours before the battery icon turned yellow. I haven't HAD to recharge before 12 hours for ages, even my Atrix went longer than that. I even have a screenshot from a few days ago where I went 14 hours and only dropped to 63%.
Are people just nuts or what is going on here?
People expect to play games at max brightness for hours and still get 12 hours battery life.
In with you, I use my phone constantly through out the day, I run my business from my phone, and routinely get 14+ hours per charge no problem. I just made a few tweaks, nothing big, and I'm good to go. This phone lasts noticeably longer than all my previous iPhones 3,3g and 4. Plus it charges twice as fast as those and never over heats... all my iPhones would get so hot that I couldn't charge them in the car with out testing then in an ac vent, and that's just from half an hour to an hour of talking... sgs3, I can talk for hours with no overheating, and it charges like a boss.

Before I flashed Cyanogenmod on my S3, I rarely reached over 10 hours of battery use with data on.
Neither one of my galaxy phones overheated to where they shut off until one decided it was dirty and jumped in the washer(rip 1st sgs2) .
I had changed my iPhone 4 back glass to one of those metal backs. Now when its on charge it will almost burn your hand if ur holding it. And I have had it shut off while on Facebook. Battery never last very long on I phones if the brightness is up data going WiFi seeking and jbing.

people complain even though they jumped from a 3.5 to a 4.8 720 screen device. Faster processor etc. With hspa or LTE speeds. I mean really. lol
My battery life is great! Much better than any other phone I've owned...12 hours of use for me is nothing....I get 18+ without a problem....frequently I've gone well over 24 hours.
Chargers. That is all.
I mean don't these people go home and charge your device?

I think some phones came with defective batteries. I'm running juice defender and could easily make it through a 16 hour day. 3-4 hours of screen time was not uncommon. 3 months later, and I can barely get 10 hours of use and 1.5 hours of screen time. Time to get a new battery!

I am not sure what is going on. I don't have the best battery life I can get 10 to 12 hours moderate use. Steaming music, reading rss feeds, checking email, 2 to 3 hours screen on. I would easily last a day on my iPhone 4. I have juice defender, lowest screen setting, custom kernel with under volting. I think it has something to do with my area. Att is so congested in my area I am barely able to use data sometimes. It's better with lte but still an issue at times.

People use their phones differently. Just saying.
If I don't turn the screen on, with LTE data, my phone dies in 9 hours (I tested it). And this doesn't mean there's a problem with it. I have around 15 different push notification apps running in the background, all of which are using data almost continuously. I don't think I can expect it to last much longer. And if I know I'm not going to be near a power source for longer than that, I simply turn off syncing to get better battery life.
To me, it looks like the LTE radio is the biggest battery hog. Let's see if the iPhone 5 can somehow get around this problem so that other manufacturers can take note

I was going to mention this. I noticed a significant improvement in battery life once I used JuiceDefender to turn off data while my screen is off. 4G LTE is the main culprit of most of the complaints for battery life (in addition to brightness). That is going to be a big problem for the new iphone if they can't get the battery management for 4G correct. It has taken Samsung a couple of years to get the battery working decent with 4G. I have my doubts that Apple could top them the first year running LTE on the iphone. Who knows, maybe that will be the "new" feature they have been working on over the year, LTE power management. That's the direction Motorola has headed in their new RAZOR MAXX devices. We'll see, either way, the consumer comes out on top as we have more competition to drive down prices and receive better products each year.
Best battery life for SGS3
With AMOLED and Android u gotta take special measures to get good battery life:
- kill bloatware. NostalgiaTurboSlim script will help. Or freeze unneeded apps - like Maps and enable them only when needed.
- disable various notifications - Play Market, WiFi etc
- disable ads - root and download AdAway app - they steal your mobile traffic, battery life and make you blind!
- put dark nonLive Wallpaper
- remove any widgets you don't use. I just removed all of them.
- disable animations and transitions
- disable haptic feedback
- disable touch tones/sounds/vibrations
- try using nonAuto brightness (I gave up on that - sunlight does not allow me to change anything manually)
- disable autorotation
- use dark Opera browser user.css
- use inverted or dark themed apps and Gapps, there is dark MMS, Twitter and Facebook in my ROM
- downclock CPU to 1GHz, or enable PowerSave On.
- use modern KToonsez kernel with PegasusQ governor, it downclocks CPU during screen off
- use CPU1 disabler script if your ROM/kernel supports it
- keep chargers around you, buy them at amazon
- buy spare OEM battery - I'm against aftermarket batteries, they are all fake rated
Or just buy latest iPhone 5 and enjoy.
Remember: Android is for tinkerers! That's why we love it! :victory:
Why do people still use some sort of battery management app life JuiceDefender or the like.
GET RID OF THEM NOW !(most of you that use it are probably coming over from an Iphone so you may be new but aren't well educated in how the Android OS works)
This phone comes with its own Task Manager as well as removing unwanted apps that are running in the background that you have previously used and don't need running.
So get rid of these dumb apps that don't do anything.

I believe this is the software bug that can be fixed in one of the threads around here. It deals with the Cell Standby that drains the battery.

I've tried all the hottest kernels and battery saving tricks and still average only 8hrs under real world use
Running Evo Deck 1.2.1, display at 12%, couple widgets, data off (using wifi at home) , sync off, and all of that. Underclocked, undervolted too.
Browsing, xda app, etc results in 20% battery usage per hour. Battery consumption is zero at idle, but drops like a rock if i use the phone at all.

Battery calibration is very important, don't know how I lived without it
Setting the VM heap to 48 allows the dalvik garbage collector to run less, improving battery
Chainfire 3d helps with anything graphical, makes home using lwps smoother, games run better etc, also saves battery by making all animations, graphics processing more efficient
If you use apps2sd bumping the cache makes it faster, and more efficient saving battery
Also updating to the latest radios etc, and making sure your prls and profile is up to date is essential, many aosp users, formerly including my self forget about that stuff
I've spent a huge amount of time expirementing with different setups, I think I've found my phones sweet spot
I have loads of friends with rooted evos, mine has the best battery and is typically fastest (chainfire 3d) makes everything snappier
Maybe with all of this info you can test these apps / settings and find your phones sweet spot. Good luck man

I'll agree with Zac here,
evo 3d with CM7 nightly, SavagedZen 2.2.1 CFS. removed all the crap i dont use or think they suck the battery down. live wallpaper etc.
InteractiveX governor, 245-1113mhz
No setCPU.
no juice defender
no taskkiller.
no 4g - no gps - no wifi
blutooth ON
3g always ON.
battery calibrated is a must
display set to manual around 33% brightness. but i change it on the fly (swipe the notif bar).
Now the results are pretty interesting here:
With the stock battery and all the above; if the reception is good, i can go for 2 days with moderate usage. yes i know i night i sleep, so it idles nicely.
If the signal is not so good, it will destroy the battery, and can't really get anything more than 13hours.
My typical use:
unplug at 10am.
use the phone normally.
plug it back in at midnight that night, and i would have between 35% or up to 67% battery left in the phone, depending on the factors mentioned.
Which to me, going all day is all i wanted before i started tweaking. Mission accomplished.
The quality of the reception is a killer, i'll tell you.
I bought a 3500mah battery from the same company, and it is trash.
are there any extended batteries that fit in an otterbox commuter case?
It feels like my phone can't last much more than a day.
Am I expecting too much juice from my phone or is this the normal amount it should be at?
Generally speaking for me I only last about 12 hours unplugged. Even when not in use on idle, i seem to lose 1% every 10-20min or so.
Someone please shed some light based on these battery screenshots and tell me if its normal or not.
Your biggest wakelock is audio out. Turn off keyboard sounds and screen touch sounds and lock sounds. Now your phone can sleep better.

You seem to have fairly frequent screen-on usage paired with frequent intervals of GPS usage (see battery graph).
Are you using GPS that frequently? If not, id investigate on why your GPS is being utilized so frequently.
I'd say based on your usage, your battery life is fairly normal.
Two hour screen time... That sounds about normal to go from full to dead. You're lucky the phone made it 12 hours. Many people get a lot less.

Two hours screen on time is normal? I hope you mean for the Verizon version..
Sent from my Galaxy Nexus using xda premium
with wifi on the whole time, that should help the battery last longer. I'm on LTE version and my battery life is similar to yours, but on 4G.
Based on your info, I would guess that you can improve it by turning off some things going on in the background. Widgets, weather, screen brightness, anything else using lots of background data or ram?
Sleeping with 4G, sync, and GPS all on I lose 1-2% per hour. But that's with no background apps other than stock OS stuff + AVG. I normally get 2.5 hrs screen time 100%-0% on 4G over a 12 hour period.
Well there's half the problem right there, facebook, it's refreshing for updates all the time.. also, underclock your phone so the max is 920MHz might save some, unless you wanna do some gaming or something it doesn't matter. Audioout seems to cause a lot of wake time for all android phones.. seen it in the epic 4g forums. But yessiree Bob.

Normal for a lot of people. Just look at all the poor battery threads. I get 2:30h with my gsm GN running Wifi and very minimal apps which sync. My browser is inverted and my screen brightness is low.
I get good standby time, but that doesn't really comfort me as I have a powerful phone I can't actually USE.
You will hear people say they get great battery life or they are fine with 2h screen time, but I just think they don't want to admit that a $700 phone in 2012 should have better life than this.
If you ask for advice, people will tell you to stop complaining and / or get a new phone. Don't reply to them or an XDA mod will threaten to ban you. Happened to me.

With standard battery and stock ROM this phone can only give 2.5 - 3 hours screen time, which is unacceptable IMO in this day and age.
Turn GPS off, turn wifi off, don't use this app, only use that app, turn sounds off, don't increase the brightness, limit the cpu etc etc... So why did I buy a smartphone that I can't use then?

I have owned more android phones than I can count, and tried more ROMs and Kernels than you can imagine. Countless times I have seem claims of improved battery life, and until recently nothing made a noticeable difference short of not turning on the phone. I am running the latest GummyNex Rom with the Franco Kernel 15.2 and it is shocking. I have verified the last two nights by leaving phone off the charger. Night #1 -8 hours 30 minutes phone sat while I slept, on 4g GPS enabled, and used 8% battery. Last Night 8:15 phone sat, same conditions only 7% battery usage. I am using the "Franco Turtle" governor and notice not performance degradation and only incredible battery life. Very impressive
I've read a lot of posts complaining about battery life, and other posts about users suggesting ways to improve battery life. I've read stuff like, disable LED, haptic feedback, lower volume, lower brightness, LTE turned off, underclocking, turning off sync, live wallpapers, etc, etc. To me a lot of people are crippling their phones. If your battery can last you 10 hours, that's enough because you'll probably be somewhere you can plug in. What's the point of being able to go for 20 hours when you'll probably have the opportunity to charge it before then? It's better to have and enjoy all the features.
Maybe somebody can chime in and give me their point of view.

I agree. I would never want to sacrifice a feature just to extend the phone's battery life. Instead I use a custom rom that has all the features (and more) and 12 to 18 hours of battery life.

Part of the issue is a sociological thinking pattern between wanting "more" and needing it. Depending upon the type of lifestyle you live, sometimes, battery life is of dire importance to have if you're constantly migrating around. But I agree, some people who aren't in that sort of disposition go overboard with it.
I just bought a bigger battery :good:
I agree wholeheartedly. If your battery is lasting you through your day (which mine does, and more) then why try to conserve it?
Yea its funny stuff people complain their battery only lasts 20 hrs but yet they want it to be able to do everything a computer can do and more....
Sent from my SGH-I747M using xda premium
The only conscious effort i made to extend my battery life was to undervolt the CPU a bit, but this was more for the lower temperature advantages with extra battery life being an added bonus. Beyond that i turned off things i dont use like BT, no need having something running that i have no use for. Overall i was happy with the stock battery except for any kind of heavy video or game usage which drains it pretty quick - solution : bigger F'n battery :highfive:
i agree that some people seem a bit obsessive about it. but we shouldn give bad battery life a pass either. hopefully we will see some sort of advancement in batteries to have better battery life while keeping them at a decent size.
i was kinda worried id have horrible battery life with the S3 being that its LTE. my last LTE phone was so bad it would die after 8 hours idle.

I keep the brightness to the lowest setting anyway, but I do all of this because I go to school fairly far from my home, and I'd like to be able to play games on my phone without wasting 5% battery every 15 minutes. I haven't switched power saving off since I bought the phone.
Stock ICS on my S3
I bought the extended battery because I like playing games from time to time and I don't want tl have to worry about my phone dropping 15% after playing something for 5 minutes. Like someone else said earlier. It really depends on the kind of lifestyle you live. I for one don't mind having the extended battery on my phone but I do miss how light it used to be.

How heavy is it? Does it fit in a case?
For me, and I want as much battery life as possible to avoid those situations where there is no way to charge you phone even if that only happens 1 a month or less.. As a parent I can't just let my phone die on me... I always need enough to be able to take or make that important calls/text. My goal is to have at least 20-30 hours of battery life per charge.
I think the only major feature I've given up is live wall paper. Other then that, it is just disabling other unused apps like gtalk, talkback, Google bookmarked sync. As well I've uv my phone as much as I can and run a 1350 max clock speed. I really don't see any major dip in performance as long as you do it right . I do use Tasker to disable syncing globally when the screen is off and make sure it automatically disable bluetooth after 10 mins once it disconnect. Also I have the Y5 app to automatically toggle wifi based off my network location. The most useful battery saver I've found is to set my wifi to only connect when the screen is on. Seems kind of backwards but it works well when very little data is process during idle rather the the phone requiring to keep a constant connection to wifi.

I'm also one of those people that closes an app as soon as I'm done with it. Use an app, press the home button, release and hold home, swipe the app away, sigh in relief. An old habit carried from my S2 Skyrocket, where getting 8 hours on stock was above average.

I have my screen brightness at 40-50 auto off.. i cant imagine turning it all the way down like alot of people say.. even when auto brightness is on it look very dull and dark at night to me.. Same thing for my tv with auto brightness.. but i still get good battery life. I am fully charged at about 6pm i use it till bedtime and use it for my alarm.. get up 4 am and when i get home at 2pm its still over 40%.. only thing i do is close all my running apps by holding home button a few times a day and same with ram
I work in an office so it's plugged in for the 2 hours before I leave so I have everything on full most of the day (brightness, lte...). Also, by undervolting I'm getting 30% more battery.
I think tips on increasing battery life like turning off lte and brightness are for people who can't plug in throughout the day or for emergency situations when you want to get the most out of your phone because there's some reason you can't charge.

I get anywhere from 12 - 23 hours depending on whether I'm at work or off. I can live with that...but there are situations where being unreachable poses a problem.
So, to deal with my phone addiction, I got an original replacement battery. Always have it charged and on me. When the phone shuts down, pop in the replacement and your done. About a minute without a phone. This way I don't have to UV, worry about brightness, WiFi, Bluetooth, etc...
I can't deal with the bulk of an extended battery.

30% more battery by simply undervolting? I think that's quite an overstretched statement. How is that even possible?

Its not possible. Not by solely UVing. The sole purpose of undervolting is so that your phone dosent overheat when running high clock speeds. Saving battery is just a perk. You might save a few percent with the undervolt but nowhere around 30%. But don't take my word for it.....

Currently running Jedi x11, and have had if for about a week now in order to test if there are infact major improvements.
I never really sat down with a timer and timed how long it took my phone to deplete, or charge, so I won't have an exact time duration for these, but I can confidently say, that since I got Jedi x11 on here, two things have started to happen.
1) Battery takes a very extended time in recharging. Both when in use, and set aside. - Previously, my battery would fully charge anywhere from 1 1/2 - 2 hours from about 15%.
2) My battery is depleting ridiculously fast. I type fairly fast, I'd say about avarage, and just for an example, I started this thread at 93%, and at this very moment, it's now at 91%... Even when not in use, the battery seems to deplete at a much faster rate. Tethering is also very draining now. - Previously, again, never timed it, but I am sure by the constant use of my phone that I've had for some time now, that this wasn't ever the case before.
This is just my observations: It would seem Jedi helps when the phone isn't in use. I'm not sure if this mentioned CPU sleeper helps with that or not, it's hard to tell as like I said, the battery goes down even when no major screen time is in use. Maybe it's something I have to turn on? Maybe not. Another, observation, when I am actively using the phone the battery will drop fast. Like, double fast.
And lastly, I observe the battery life will stay on a certain percentage longer than it does others. (Currently 89%) I took about 10 - 15 minutes writing this.
Any thoughts? Thanks for any replies I do get.

I'm glad I'm not the only one with this problem on this rom. Phone takes 9 hrs to fully charge, I was starting to think I'm going crazy. My battery will charge fast if I go back to stock. But I would hate to go back because of this.

Well guys, I'm not sure what's going on, but, it should be noted. The Battery on this thing just lasted the entire evening from last night (7pm) up until now, with about the same amount of use that I did the days before when I noticed abnormal battery depletion.
Currently at 47% and I've yet to charge the phone. Of course that is with the fact that I put the phone in airplane mode while I sleep for a few hours. I watched a lot of video, listened to audio, and it's as if they thing knew I wasn't pleased with what was happening, it's now behaving like it should.
This happened a few days ago also, where the battery lasted 16 hours and was at 27%. So this leads me to think it's something that happens on and off, and I have no clue what triggers it. phone ussage rains the same. Took about 5-7 minutes writing this, and the battery marker only went from 47%, to 46%.
Credit where it's due.

a lot of factors involved when it comes to battery. based on my experience, try to see what's going on with your system using this thread. noted post 1-3. also investigate about your kernel. i am using perseus kernel and my charging time is pretty good improving than on stock :good:. also i can undervolt CPU.
where you at and which service provide you use, again, have impact on this case. i used to be with t-mo and now trying h2o (att mvno) and my battery is dropping faster when i use data. i believe since at&t coverage is suck where i am at, specially when indoors, thus phone radio has to work extra harder to get reception and shorten battery's life.

In the early days of Android CPUs were not very efficient. Undervolting helped battery life. That is no longer the case. Most good kernel devs will tell you they hate under clocking because it has a placebo effect and makes their kernel unstable.

thanks ronnie. it's good to know. wondering why some of them (well known, i believe) still offering CPU voltage adjustment (up & down) if they see it inefficient ? is it because the kernel still in beta thus come with tweak utility ?
Yeah, there is definitely something awkward going on. I took my phone out of airplane mode this morning and started viewing FB for a couple minutes; a battery that was at 98% is now somehow at 92%. It's definitely on and off. I wasn't even watching any videos or anything like that.
Would all the apps that are in ram be sucking juices this badly? I had to terminate a lot of em just a minute ago. Or, is this thing somehow giving me a false charge reading? Battery seemed to charge faster than usual last night.
I'm not even fully certain the devs read these question forums at times.
I'm runnng the international XXDMB6 based ROM on mine and currently, I'm at 76% with only an hour and 3 minutes of screentime?
I don't use Wi-Fi.
My LTE signal is rather poor.
My screen generally stays around 50% but it's on auto.
Of course I let my apps sync. But that's pretty much just gmail and facebook.
I have my weather set to sync once every hour.
I uninstalled the apps that are pretty much bloat (flipfonts, the hubs, the samsung live wallpapers, musicFX since I use DPSManager, Samsung's music app and that's all I can think of)
I'm running Perseus's kernel with about 200-350mV undervolts.
Is it truly the poor LTE signal that's taking such a toll on my battery life? I used to average 5-5.5 hours before my battery dies. Now I'm betting I'll only get around 4. When I had Verizon, the power draw from LTE was unnoticeable from 3G. Is it really that different on GSM phones?

Battery life is very noticable with lte. Reason being that volte doesnt exsist yet so two or more radios jeed to be active at the same time.

I found Battery Drain Analyzer helpful. I kept it running for a couple of months and was able to determine which apps consume the most power (widgets, by far). But, after having spent hours trying different underclocking configurations without success, I ended up buying three extra batteries. It's really awesome to not have to worry about it. I just keep them in my pocket and swap them out as needed. It's not a very technologically advanced solution, but, it sure is effective. I use this Charger for the spares. It takes a long time to charge the batteries, but charges them fully to 100%, whereas, charging the battery in the phone doesn't seem to work as well.
I am extremely frustrated. My phone has always been bad with battery life. Its been over a year or so that I have not seen my phone last longer than 5-6 hours. I am constantly looking for any chance I get to charge my phone. My life revolves around checking battery %age and plugs to charge. Smart phones were suppose to be helping us, but its like they are using me to feed the juice every chance they get.
My T989 is a "SMART" phone with
- lowest on screen brightness (and a screen dimmer overlay)
- no NFC
- no haptic feedback or keytone sounds
- No animations or graphic heavy launchers
- dont play games any more
- turn off 4G/data anytime I get a chance
- No GPS
- Manual Sync emails, facebook and whatsapp
HELL, I want to go back to the age of Nokia's where the batteries would last you through weekend and still some juice left even after it goes through laundry.
But that is not what I am here to complaint about.
I would like to know what ROM+Kernel you have and how much battery life you get ? (w/ screen time)
Who else is going through these ?
Note: Currently on JB stock and a new OEM replacement battery
How often are you using your phone? It uses a lot more battery when the screen is on. You can get over 24 hours of battery life by not touching your phone at all/no apps running.
I think most people average around 3 hours of display time without charging. Check in settings/battery/display.
I'm running AOKP and depending on how often I use my phone it can really deplete my battery.

easiest way i have found to extend my battery during the day is to toggle my data..if i am not using it for a bit, just toggle it off, takes 2 sec to toggle it on, and can easily double my battery life..
I use Jedi mind trick with Tiberius kernel. It fly's and I get around 12-14hrs with 1hr and 30mins or so with Facebook 1hour and half of music and texting. So get it!

Do this stuff and read it carefully. And yes 3 to 4 hours is about average screen time. Makes no difference discussing total battery time. You can kill it 3 hours from a full charge with continuous use...or it can last 24 hours....all depends how often your using it and what you are doing with it.
If you go thru this other thread and follow all of the advice ....you should be fine.

These are my results, after buying the LAZA 3800mAh battery. I just had it for one day and it is light years ahead of the stock battery. I don't use NFC, and my brightness is all the way down. (Still I don't believe the brightness is low enough, seems too bright). I am a student so when I'm in class I can't obviously use my phone, so that is why the screen time is below what you guys expect. Still this battery is legit! I got it for $23 shipped (Amazon Prime). On the stock battery I had to revert back to ICS, but with this Laza battery I have no gripes on leaving it on the latest CM10.2 (4.3.1) and letting it go on Dual Carriage (DC, HSPA+42) mode. As long as I leave school with more than 70 percent battery like on my HTC Sensation, I am fine.

I do have GSAM battery monitor installed. I had it installed since it was called "bad ass battery monitor". It always is consistent and shows that screen uses most battery (abt 35% of overall usage), even at lowest setting. I also have a screen Filter app https://play.google.com/store/apps/details?id=com.haxor That overlays on the screen that dims it even further and is believed to save some more battery.
The other major user is the apps which is
- Android &
- Kernel

I will try the cpu spy again. I remember doing it before and it was almost inconclusive if there were things I could control vs system related drain that I couldnt control.
I am currently on a new OEM battery (2 months old) and several ROMs later,. Some ppl claim they get best battery life, I just want to mirror exact same ROM, kernel... even the apps they have and their refresh settings if I need to.

Dude.....less than an hour screen time tells something is very wrong.
First...I would bet the screen dimmer app Burns more battery than it saves.....that'd be my guess.
Second....flash a fresh rom, or stock. Run it at least a few days as is. With only gsam and cpuspy installed. Nothing else. I know you may really miss some apps....but its the only way to see if its an app, or rom, or hardware.
Then off gps after your install. Its on by default and is a huge battery sucker.
I'll bet things will be greatly improved. Then install apps.....monitor closely for changes in gsam or cpuspy.
Your screen battery usage should be more like 60 percent or higher....even as dim as it goes. That's normal. Apps, maybe 30 percent and then the other stuff. A 35 percent battery drain from the screen says you have problems.
After all your apps are installed.....try everything in that link I posted. Everything. And things should stay good.
Keep us posted.
