Battery issues

My phone has TERRIBLE battery life. It lasts about 2 hours usually and sometimes 2 and a half. I'm running the stock GB from that came with the phone, but I am rooted. I have tried every single from out there..none of them give me sufficient battery life. By the time i get home from school by battery is down to 30%. What could be causing this? I'm also on my third warranty replacement phone and my second battery.

Normally I would suggest going to stock for people but in your case, maybe custom is the answer.
Do you have loads of apps and accounts setup by the way?

This really has no useful information to be helped. 2 hours? On stand by, screen on time, any cpu tuners, etc?
Maybe take screenshots of what the battery chart looks like and what apps have the highest percentage.

It is about 2 and a half hours of screen on time. And I can't get a screenshot of it because I just flashed a new rom, and my battery hasn't had a chance to settle in with the new rom yet. If it doesn't improve I will post a pic of my battery stats. Thanks.

Well, I'm guessing there is an app that keeps running constantly. You should try an ICS ROM, that might help.

Same problem
I've been experiencing identical issues with my T989. I've had terrible battery life without many apps running in the background (as I use the stock task manager to execute all running apps). I've finally decided to root my device and install a 'set cpu speed' app. Even though I've set my minimum cpu speed to 200 MHz and max to 800 MHz it's still lasts for a maximum of 4 hours until I get the "Battery is critically low" message.
Does samsung provide warranty for their batteries? Because I've called to complain about battery life and they asked me to remove the battery and send the device itself so they could repair it. And under no circumstances would they offer me an exchange for the battery, maybe I just caught a bad rep?
I love this phone and all it's features and prefer this over the iPhone but I feel like i'm being forced to just purchase the iPhone 4s.

Post your battery life

I don't see a thread like this for the T-mobile variant so I figured we can have our own. It would be nice if you included the following with your posts:
screenshots including on screen time, information about your rom, kernel, etc. and estimated talk, text, browsing, and gaming time, and what brightness you had your screen on (auto, full, etc.). If you use something like SetCpu with profiles list your profiles and settings here too.
I'll start:
This is only my second cycle charge on this device. I only got it 2 days ago now which means it still has room for improvement
My sig has my rom info and I basically did a lot of twitter browsing, about 100 texts a few short minute phone calls including an hour long call when it was at around 10%, a lot of XDA reading, and no gaming today.
I have the device overclocked to 1.89ghz with this kernel with min set at 384mhz ondemand governor. I have a profile that clocks down to 1.5ghz at 50% battery life and another that clocks down to 1ghz at less than 10%.
I've never had a device give me 4h on screen time especially with the abuse I give this device. I can't wait to try out other kernels and roms to see these numbers rise.

I could get a day and a half with no tweaking and low usage, on an average day I'm getting ~15 hours before it starts whining about the battery

Yeah but what's your on screen time?

Right?! That's what it comes down to. It doesn't matter if your battery life is amazing if the reason why is because you barely if ever use your phone...

Throwing bricks since 2008.....and proud of it.

I could make it 24 hours easily with light usage. With moderate to heavy usage, probably around 20 hours. It really depends on how long the screen is on though. This phone has amazing battery life. My HTC Amaze probably only lasted half as long.

I agree, best battery life I have had out of all of my previous smartphones. I am still testing roms and kernel combinations to figure out what works best for how I use my device. I'm in the middle of testing FSG3 rom with trinity kernel. Will post up battery usage within the next 2 days to compare to my previous Stock rom with Adama 003 kernel battery life.

My Screen
Pretty Good so far, Stock Rom - Rooted - Still 40% left.

This is with the fsg3 rom and trinity kernel. First and only cycle so far. Brightness 100% wifi on most of the time, and data and gps always on. Played music for about half an hour and browsed xda for half an hour.
Edit: screen on time was just over 4 hours deleted the ss by accident.
Will post up the 2nd cycle when it's done.

Look at screen time on not just total battery time. This is what determines good battery life not letting your device sleep on your desk for 2 days and saying you get amazing battery life.

Fantastic battery life on 4.2

Battery life is very good compared to the previous releases. I ran for forty minutes with Bluetooth turned on while listening to tune in radio and using endomondo app. Google now turned on. I lost fifteen percent compared to losing 35% with similar usage. Very satisfied.
What do you think?

Ditto. My phone ran like a champ on a freshly flashed ROM. Then my phone realized it was born as a Verizon-Nexus mutt and had a psychological breakdown to the point of 1.75 hours of on-screen time the day after.
Twas a sad day

I'm reading my work email over the exchange service account. After upgrde to 4.2 the exchange service process eats my whole battery so I can't tell about any improvement.

When it comes to battery life (in general, though especially true with this newest release), it's crazy how many divergent opinions you get. Some people claim to get amazing battery life (exactly what quantifies for amazing?) and some people claim the battery life is crap. This is just to remind you that unless you have a good way of measuring battery life, your measurements can be plus/minus hour(s). Someone who just leaves their phone on a black screen with no wi-fi and cell may get 10 hours of screen-on time. Someone who is watching videos with cell/wi-fi might only get 2 hours of screen-on time.
In the future, I can make two recommendations:
Always report a complete cycle (from 100% to close to 0%). This is because the battery does not discharge at a constant rate.
Always report screen on time
Average for GNexus in previous builds was 2-4 hours. I've no idea about the plus/minus, but they tend not to be under 2 and over 4 with moderate usage. I think an average of 3-3.5 hours is what most people are happy to report.

And that is really sad because my old atrix used to get over 8 hours on Wi-Fi with over twelve hours of standby time. I wish they would make this phone but with a smaller screen size. The technology used on this phone is not battery efficient at all.

This tells us nothing....u don't show ur screen on time and uve been charging off and on..

Battery life in sleep mode is worse for me. I am losing 3% an hour with the screen off, I used to lose only 3% total overnight with the screen off not per hour. I tested this over the last 4 hours only waking the tablet up long enough to check the battery level and it has gone down by 3% each time. Nothing has changed with any apps or setting since I upgraded from 4.1.2 to 4.2. I got concerned when I noticed this morning that my battery was over 15% less then when I went to sleep. Anyone else notice this?

This is very good battery by my standards.

I use my phone as usual reading emails I have push mail on always and also i have facebook checking in every hour and also a voicemail app checking in every 30 minutes, I browsed the web a bit googling information. Im not much of a talker so talk time would be low (Its 16 minutres and 4seconds). Also the place I work in has very varied reception some places being completely 0 bars no service to some areas giving 4 bars but mostly low reception.
This is all to give an idea of how I used my battery. Im sure if I had it lying in a corner with data off and not using it all it would probably last a week.

I, personally, don't focus on battery life at all. I run Bluetooth all day, listening to my music, play games on it during my lunch hour and other times throughout the day and send texts/emails off and on all day, and it's down to about 40% by the time I leave work on a normal day. That's unplugging at around 7:30AM, and leaving work at about 5-5:30PM, so that's about 10 hours mid-heavy consistent usage.
To me, as long as I get my full day out of it, I'm perfectly content with it. I don't need my device to be a battery warrior, I need it to be a power beast and do what I want it to do, when I want it to do it. I personally dislike apps like Juice Defender and those that disable radios and data on me. I also don't like using CPU scripts to limit the CPU, undervolt it and all that. To me, it just seems contradicting to buy a powerhouse like the S3 and then strip away it's best and most powerful features. I also don't like the small influx of bugs that arise when you start doing things like disabling data and limiting the CPU/voltage. I like my smartphone to be as smooth as possible, all the time, without any hitches/bugs.
I'm a very heavy user and rely on certain notifications as they are sent out, so extending the battery by an hour or two is the most I could hope to gain by using these apps/scripts, and the level of frustration that come with them when I get syncs late or things are sluggish isn't worth it, imho.
Don't take that the wrong way, I'm not saying they are bad apps at all, nor are the CPU scripts completely pointless. I would give them a high rating if asked, because they do their functions well. I'm just saying they don't work for the way I use my device.

Why is aosp (AOKP/cm10.1) battery life so abysmal?

From what I've used aosp ROMs tends to have pretty bad battery life in comparison to stock tw ROMs. My question is why and how it can be addressed? Now I've used a multitude of aosp ROMs including cm10.1, aokp, and root box just to name a few (all 4.2.2) and my battery life is pretty bad. I won't post any screenshots because it varies but take my word for it, took it off charger by 10am by 2pm (2 hours of screen on time later) it was already at 30% (this was underclocked to 1.2ghz mind you) I think my only option is the nexus 4 at this point as it has stock android and I've heard it is having fantastic battery life on 4.2.2. We'll see, anyone have input on this?

I really don't know what I'm doing wrong, I've tried underclocking, undervolting, brightness adjustments, battery saving apps, etc. Different kernels too (lean, kt, bms, stock, etc) with different governors and io schedulers. I'm so fed up at this point. I want to use my phone without worrying about if I'll have enough battery left. I refuse to use touchwiz.

You might have a bad battery. If you don't mind the bulk or weight, I would recommend getting the Zerolemon 7,000 mAh extended battery. Then you could go a couple of days without charging your phone.
If you do want to keep the slim and sleek look of the S3, Zerolemon also sells 2300 mAh batteries (which are 2400 mAh) for $20 for two of them on amazon.

Ktoonz with a matching nightly.

Battery life actually varies per device an usage. I use some on my S3 an rarely touch it, the battery will last practically all day long. Also if you run a high over clock that will destroy battery life, along with too many apps running at the same time too. A simple underclock with a good governor can extend battery life too. Staying on wifi helps too. There's many ways to get good battery life for you device. As Faux123 said "every device is different". Even though we all have the same phones, some act differently.

Pretty much nothing you can do, other than maybe turning off sync and using airplane mode at night. Also, the latest nightlies after rc2 seem to have improved battery life, though it's still not impressive by any means...

I feel the same...I hate touchwiz so I'm forced to use CM10.1, which had been giving bad battery life ever since the 3.4 kernel update back in march.
I disabled all sync for all my accounts, use greenify, always keep screen brightness at lowest, only turn on WiFi or data when I need to use it, and did a clean wipe, yet the battery still drains faster than a bloated touchwiz ROM.
