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.

Please help me with my Nexus

How do I get this phone to hold a charge for a day? Right now I get about 6 hours of battery life if I am lucky on decent use.
It is rooted on a black ice rom, running that Franco kernel. Is there something that I am not doing? Do I have to overclock it or?
I seriously almost traded it it for an iPhone just because of the battery issue. Like, it drives me insane and it takes away my freedom lol
Any help would be great

if you're only getting 6 hours, then you're a heavy user. Not much you can do about that, except use your phone less or charge it more.

Run stock for a while...
Sent from my Galaxy Nexus using xda premium

I'm on sprint and out of the box it was bad bad battery life. I'm sticking with it though hoping someone comes up with a way to get better life out of it.

Use an app like CPUSpy to see if your CPU is ever going into Deep Sleep mode, and an app like BetterBatteryStats to figure out why not. You can also look at Settings > Battery to see what's using up your battery. Tapping the graph at the top may give you more details.

I really am not a heavy user.
So switch it back to stock?

Usage varies man .. i have decent battery life so far with Franco 185 linaro with AOKP linaro rom. I keep the governor set to conservative . And I do overclock as much as I can ...might even be better if I didn't do that . But I get around 10- 14 hours on that setup . I text a good bit and twitter occasionally but spend most of my time on flud news reader. If you stream music all day or Netflix or something then you aren't going to get great battery life .
Make sure your screen brightness isn't high when you don't need it to be ..since the screen is generally what uses the most battery .
My best battery was with lean kernel and slim rom 4 ...but since I went to this new linaro I will forfeit a little battery for fluidity.
The key is just to experiment. There are lots of combos out there and they all work differently for us. There isn't exactly a one stop solution . Just tinker and you will find the light
Ps: I have the 2200 extended battery from Verizon . It is a necessity if you wanna get normal usage. They are listed at forty bucks or something through Verizon ...but if you go to the store they sell them for 20.

Best solution would be to get an extended battery to last you the whole day or an extra cheap one to swap with at the middle of the day

What is your screen on time?

Yes, do this before blaming the phone. Also pay attention to the apps you install and see if any of them are causing the problem. Stock roms are usually less buggy than custom roms.

You would also get more help with your Question in the actual Q&A section.

Need battery tips for 6+ hrs screen time

Hi guys using wicked with trinity 7b. See a few people posting 2 days on one charge and over 6 hours screen time. Would like to know how as i cannot get anywhere near that. I use system tuner, odex my Rom and kill my tasks whenever possible. I use lh2 modem.
Anyone with huge battery time please help us out here. I'm sure many of us would like some help. Also if you tweak your build.prop press share that.
Looking for details. I'm not a noob
sgs3 : wicked v6 Rom : uv : odexed : trinity

They are not using the stock battery. If you want battery like that, buy an extended battery. That is the only answer.

What I find most telling in many of these screen shots is that Device Idle and Cell Standby are almost always in the top.

Cell standby is actually lying. It was coded with a decimal in the wrong place and so it shows that it uses a lot more than it actually does. Purely cosmetic really, but can be annoying when testing battery issues.
Edit: many custom roms have corrected this btw.

Ya, I saw that before. There is a zip floating around here somewhere that moves it from .34 to 3.4 and fixes it. But you're right that most custom ROMs have this (Cell Standby) fixed.
I just mainly think that Device Idle even being in the top 3 or 4 is a very telling sign that the phone is not being used very much.

Install the easy battery saver app.

I hate to be the jerk... but OP has spammed every rom thread nearly bugging about screen time. Nowadays its hard to get 6+ hours of screen time. Maybe switch to an older, dumber phone with not as sexy as display and you will have better luck. Or carry a spare battery... or strategically place chargers in common spots.

The only way i could probably make 6 hours screen on time would be to lower brightness all the way down, turn off data whenever Im not using it, turn of autosync, underclock and undervolt. But then what would be the point of me having such an awesome phone

I do all those things (-underclocking and undervolting), and more, because I don't need most of this on all the time, and my screen time is great. Plus, I bought a 4400mah extended battery & get 4-5 days on a single charge.

Then u need an old nokia.

When you plug you phone in the charger the hours reset, my screenshots were to show that its not impossible to get 6+ hours, if I under clock and turn everything off I can probably get that.
The liquid smooth ROM has amazing battery life, you should give it a try I think you will like it.

Screen shots are great guys. I do want to see them. Most importantly trying to see if there are deeper settings and apps to freeze or avoid and tweaks to build.prop etc.
Rom and kernel and modem used would be helpful.
Also, you did charge but the timer will only reset when you fully charge the phone.

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.

I was on Blazer GB a long time ago getting great battery life.[1 day]
After flashing all Cyanogen Mod builds for ICS and JB then to Paranoid Android. I have been getting bad battery.
I'm not blaming CM or PA .

I used ICS from August to December. The eye candy was nice, and the speed was enjoyable. It felt good to run the latest and greatest.
But the battery life was killing me. I have two batteries, a generic Chinese battery and a bloated OEM battery.
I would go 8 hours a day without even touching my phone, and the battery would be at 20 percent, or even dead. With the bloated battery , max was 3 hours.
I had to go back to gingerbread. Installed calkulins on December 3rd, and Juice defender.
Now I get 10+ hours with my Chinese battery, and 8+ hours with the bloated battery.

Good point! You should definitely take a look to see if the battery is swollen, it is an indicator that the cells are imploding which results in terrible battery life.

I've been hearing a lot of people having problems with their phone turning off right after the boot animation. After the boot animation, the screen flickers and the phone turns off. You will have to plug your phone in to your charger and then turn it back on for your phone to boot up. This is due to your battery going bad. Take it to the nearest Sprint store and they will replace it for free if you have insurance.

Battery is swollen 2 out of 4. 3 are ebay cheap OEM generic LOOKING, but 1 works. Then I have the Sprint offered extended battery works fine.
It has to be that. Some ROMS are killing battery quick too. I use KMS app to kill media server temporarily then it goes back on after a while maybe after 2 hours. But after I've underclocked 200/800 Pegasusq, noop i/o, I've had better life. Not excellent.

Leaked stock TW FL16 doubled my battery life from snipers latest PA 2.5.6. Main difference? Less time "awake" in battery stats. I switched back to stock ICS under same conditions (apps, gps, Wi-Fi on even when not connected) and the leaked stock TW FL 16 was still better. "Android OS" and "Android system" dropped to 4th and 5th on battery consumption percentages. Can't freakin wait till the AWESOME developers that support this device get source code. Then we'll see good battery life again. Maybe not GB good, but better than lately.
