Poor Battery Life

Hi All,
My Gnex 9250 has a poor battery life, My brother has the same phone and his battery last much longer(with 3g) than mine. Please help.
1130 AM - Battery 100%
1 and half hour Music(Player Pro) - Not much screen activity(with 2G enabled)
2G on for 6 hours, Pretty long texting.
about 45 Minutes of Browsing(2g)
10 Mins on Voice calls.
No Widgets.Background apps = Swiftkey,Go launcher(No theme),Profile scheduler.
By 12am battery was 20%
Screen brigntness is VERY low so its not that, Its about 20%.
Phone is about a month old.
Thanks in advance.
EDIT - 4.1.1(No available updates)

The fact your battery goes over 12hrs seems it's not too bad with moderate use. And who knows if your bro uses his as much as he says? If you want to compare then look at his battery stats in settings next to yours.
Try a different ROM? Kernel?

Thanks for your reply.My brother does use as he said, Ive seen his battery stats, uptime was 1 day 9 hours(14% then). He doesnt text half as much as I do, but his voice calls are much more than mine. Also hes on 3g thats a bigger battery hog than 2g. Not too keen on changing the Kernel/Rom.
Could it be SwiftKey and Go launcher? He doesnt use either of them.
Thanks again.

there are lots of thing that can affect your battery life one of it is the kernel ur using.
I already have this problem before.
i've tried lots of custom rom. the only custom rom that solve this battery issues is from Android Revolution HD 7.0.0
from this: http://forum.xda-developers.com/showthread.php?t=1361348

imo the best battery/performance kernel out there is franco's. try it, battery will be 2x to 3x longer.
if you like to fool around with what's chewing battery you can get better battery stats and it will tell you what keeps your phone from going to sleep. sometimes nothing, sometimes crappy app that messes things up
good luck!

Thanks to all for your replies.
Guess that 12 hours is not bad afterall right? Seems like that from the first reply I got.
Unfortunatly I have no time to re-flash a differnt ROM/Kernel. But thanks for all reccomendations.

You say that your brother doesn't text as much as you but he uses voice calls more. Remember that when you're texting the screen is on and that has a big impact on battery life.

There's not a kernel, ROM, or flying saucer out there that can triple battery life Just saying. People get fanatical about certain ROM/kernel combos. The usual suspects are leaving on things you don't need and on occasion an app. People claim that different things work better on different phones but I think it's a bunch of crap. Much of what you hear is placebo.

[Q] Battery Life - What are you getting?

I don't know that I've ever seen this explicitly stated by anyone, so I thought I'd ask straight out.
What kind of battery life is everyone getting?
On average, say, per hour, with moderate use how much battery do you lose?
Are you stock or rooted? What ROM and kernel if rooted?
And... GO!
Screenshots welcome and encouraged!

Everyone's is gonna be completely different. Most will post in the roms what they are seeing on avg. There's to many variables that go into that to really narrow things down. Just my opinion on that.

I understand that everyone is going to be completely different, that's the point. The idea is that if people were to post a wide variety of conditions, along with their battery-related results, others can try to tweak their settings closest to what fits their needs.
Yes, it is easily found amongst the forums for individuals ROMS/kernels, but why not put together a one-stop-shop for reference?

IMO better to keep with the Roms/Kernels (Under development) or someone may mistake and try to add something to a rom that doesn't work. Just my thoughts, I understand the goal, and I'm always looking to improve upon my battery life for my use. Haven't had phone a day yet to have any real results yet to mine.. We'll see how the world chimes in on this too tho..
Current: The Peoples Rom, 69% battery remaining, 6 hrs 14 min on bat, 1 hr 20 min screen on. Just to start it off a bit.. Will update this evening.

I'm stock non rooted with fairly heavy useage and Juice Defender free and I'm sotting at about 9 hours and 15% battery

On wifi, about 4 minutes per percent of battery for screen on time + 2 hours per percent for extra screen off time. This is with the screen brightness very low though.
So, about 400 minutes of continued usage or 200 hours of standby.
Odex blue 1.2 ROM, Google Now off, report location in Maps off.

Alrighty, now we're rolling... Here's where I currently stand:
5h45m on battery - 47% left... Heavy use today though.
AOKP Rom, KToonsez kernel - undervolted and slightly underclocked.

Charging my phone now. But yesterday i got 27 hours before reaching 25%
ROM: Stock Jellybean Touchwiz (rooted of course)
Kernel: Ktoonz kernel for touchwiz (using Ktoonservative/noop stock voltages n touch boosters disabled)

I'm stock and can get 24 hours+ with about 3+ hours of screen on time easily. This is with brightness at about 80% and no battery saving options on.

Avg around 25-26 hrs.
SlimBean w/ KT747 kernel
Under -50mhz, UC to max around 1200, cm9 auto bright settings and juice defender
-SlimBean...the bulimic's choice for the Galaxy III

Just a full days usage and still half my battery left. No custom kernel or stuff like that. CM10 and that's it

So this might not be the forum but hopefully someone will take pity on me and point me in the right direction.
As u can see. This bad boy ain't even sleeping. If not for juice defender i wouldn't make it through the day with moderate use. Now I'm in the islands where there ain't much good service to begin with so this might get a Lil tricky. Also i am unrooted. If that helps. I think it's an app but i guess i need to find another app to find the app that's the culprit. Thx in advance.

Excellent! with heavy use of ~ 200 emails a day 1h on internet and about 30min looking up news and 1-2h of calls i get 12-16h.

I tried the best I knew how and I couldnt kill the battery for 2 days. I ran everything at once (not truly everything) and it just wouldn't die.

Battery is ridiculous. After diagnosing my wifi wakelock issue and installing jedi rom I get 4 hoursish per 1% when it goes into sleep, and that's in a basement mostly with horrible reception.

im getting worse battery life ever since the multiwindow update. not sure if anyone else has the same issue, but it seems like tmobile users are complaining about the same thing. it might be due to lack of battery calibration.

Well, here's a visual. Just achieved this impressive feat. 81 HOURS on pure battery! Almost 3.5 hours of screen-on time. I choose to not utilize my phone much over the holiday weekend, so that explains the low screen-on time. Regardless, I think these results are more than impressive. Nothing was restricted on my device. Live wallpaper going the whole time, auto screen brightness (usually a high setting), WiFi going, auto-syncing from emails to Facebook to Twitter, watched a bit of "The Dark Knight Rises" in full-1080p HD, made a bunch of miscellaneous phone calls. I am more than amazed at this phone and its battery. Haven't seen anything close to this in more than five years or so. These results are after updating to 4.1.2 with multi-window, and these are the best results I've ever gotten on this device.
On a side note, if anyone is getting results like the first poster with 8+ hours of screen-on time, it would really help if you described what you typically do with your phone and what you may have done to your phone. Just posting a screenshot tells nothing. You could be web browsing all day with your screen set to 20% brightness, and nothing more. What are you doing? Watching movies? Listening to music? Emailing? Texting? And if you're rooted that makes a ton of difference, so the results wouldn't be exactly truthful or accurate I should say.

Sorry for the lack of detail, I should have included that. I was browsing the net on wifi, playing Words, emailing/texting, various phone calls, watching youtube videos, and spending time on the XDA app. (of course)
I'm rooted and using clean rom 3.5. Auto brightness is on and I'm about 50% on the slider.
Here is where I sit today: (not much youtube though)

^^^ Thanks. So, that does change things, since you're rooted. The reason why I'm making a big deal about it, is because your results (and anyone else rooted) aren't typical results of someone stock. So a person not knowing any better would assuming they'd get your battery results from stock.

How is that possible? I use my note for about 5hrs of screen time and it's at like 3%. I am on an international rom and I undervolted along with perseus 1.8ghz kernel. Even when I did not have perse us, I never got above 6hrs? What settings do you use? I'm on wifi all day with the brightness All the way down. Please let me know! I really want to get that 8hrs of screen on time!

Clean Rom 3.5, I also make sure and close out of anything I'm not using. I also use the ES Task Manager widget to clear my ram before I power down for any period of time.
That's about it, besides not having a ton of widgets running.
I didn't get much over six hours of screen time with my Jedi Rom, but in fairness to it, it was my first rom and I don't think I did it quite right, installing other things with it that probably weren't compatible.

Like Dr. Evo points out, one of the great things about custom roms is they get rid of all the bloatware from ATT and other carriers. Stock I was lucky to have 1gb of free ram at any time, now I'm always around 1.1-1.2gb free without much effort on my part.

Battery life on the Sprint Galaxy S3 L710

I'm a new android user. I'm using the LiquidSmooth 4.2.1 JellyBean Beta 2. The problem I'm having is with my battery life. I seem to average about 5-7 hours of battery life which is crazy if you ask me. This isn't a ROM issue either because it was the same way on the stock 4.1.1 Android OS.
I'm using JuiceDefender now and that seems to help a little. I know things like disabling 3G and WiFi can help but I use these things often. Can anyone offer any useful suggestions to extend my battery life?
Thanks in advance

The quickest way to answer this is to suggest you use search. There are already dozens of posts/threads about this. A lot depends on signal and applications running. Do some reading, more than likely you will find the answer already posted.

Absolutely something wrong with your phone and or battery. Had an S3 since July '12, rooted and ran FreeGS3 and had all day battery. Lost that just before Xmas (actually stolen) and got another S3, and this time decided not to do all that ROMming and flashing and stayed stock 4.1.
Same all day battery life with WiFi on, 3G on, Google/Gmail Sync on (i like my push Gmail), several email accounts polling, etc. I just use my phone, no gimping with apps like JuiceDefender (which i detest with a passion).

Heres a question, what's your screen on time? Cuz if your phones dead at 7 hrs with 5 hrs screen on your first option is to adjust screen settings and the second and 3rd option are put the phone down sometimes and/or keep a charger handy

Depending on how often I use my phone I get anywhere between 9-11 hours on light to moderate use. Meaning listening to music, Twitter, Instagram, email, and texting

It could be the 4.2, because it isn't completely "stable" yet. I'm on stock 4.1 rooted, with screen brightness on I'd say 30-40%, with light to moderate use and can get 11-15 hours easily. This includes texting, maybe a few phone calls, lots of music, and some Facebook or XDA on a WiFi connection.

Well after checking out the Kernelizers thread and flashing the KT kernel onto my Galaxy S3 and installing ROM Toolbox, my battery life has greatly improved. I also installed DS Battery Saver Pro. I just came to work. Left at 7:05AM, put on some music, and by the time I got to work at 8:05AM, my phone battery only dropped 3%. Normally it would drop at least 10% in this time so what I did is clearly working

I would uninstall DS Battery Saver Pro. If you did check out that thread, the phone already deep sleeps. Mine does with no additional app assistance. Went 38+ hours and still had 25% battery life left.

[Q] Help!!! Battery problem makes me wann commit suicide.

I really am close to killing myself due to sadness and disappointment because of my phone's battery life. lol. I have a Galaxy Note 2(4.1.1 ver) and my battery lasts for 12-16 hours. I use it mostly for Facebook, Google, Viber and YouTube. I have other typical social networking/comm apps (YM,Skype, Instagram,Twitter) but I dont use them often. I have less than 10 games (Temple Run2, Angry Birds, Diamond Dash) but I dont play for more than 15 mins. I have observed that when my phone is NOT in use, it decreases by 7-10% per hour (sometimes 1% per minute on idle) during the day. At night, before I go to sleep, it is a fully charged phone and when I wake up, 25% of the battery's life is gone within 8hrs of not touching it even to check the time. I dont know if its the normal draining rate of the battery, if its a factory defect on the battery or the phone itself, or if it is the app or android system. They say you need to turn off the location or something but I couldn't seem to find it. My phone is just 4 days old, or maybe 5. Im hoping when the phone turns a week old, things will be better. Or should I try to kill myself now? Any possible solutions???
PS. Please try to use "simple" instructions or terms. I really am not good about technology.

Update to the latest firmware.. and then do a factory reset.. do take up back up before doing the factory reset. what is your screen time? post screen shots of your battery stats.. and committing suicide is not going to solve your problem.. but still remarkable that someone considers this over battery woes..

please say to us which apps are you using because there are lots of draining apps. sqich off gps brightness at the minimum values and so on if you haven't done it yet
hope it worked to you

Here you go gentlemen

It doesn't say much, I mean are you playing games such as need for speed or similars? is you brightness at maximum? I use the battery saving feature of the phone and I have to say that there is no difference in performance but there is in the battery I mean it last a more than in "normal" mode. if you already tried it at it still has that draining do full wipe and flash a new rom.
Hope it was useful

Good Lord! You wanna suicide for some ****in phone's ****in battery life? Come on man. This is a simple gadget, not your child or family. Use it heavy, have fun recharge it, throw it when you are done, then use it when you in need again.
Anyway, I think you are using 3G, turn it off if you don't need it, you'll notice massive battery life increase, but if you can't disable it then I will say get used with that.
There are two simple things,
With 3G- Moderate battery life. You CAN NOT do anything to increase it.
With 2G- Solid battery life.
PS: IMO, 4.1.2 has even bad backup.

your phone has a decent battery life... at 50% your screen time is almost 3 hours which is good enough... Well now live your life:fingers-crossed: and enjoy Galaxy Note 2.. it's brilliant :good:

what a wicked world we are living ... suicide over battery issue?
try install betterbatterystats from xda ... it'll let u know which rogue apps sipping away your battery juice :good:

You must have high expectations, 12-16 hours for a charge isn't that bad, especially if you're actually using your phone a decent amount. You won't be getting a week's worth of battery at a time.

Nice thread!! u got everyone attention..lol

looking at your pic... it looks like some rogue apps is keeping your phone awake eventho your screen is off

So how can I find the culprit? Charged my phone and will show you shots from betterbattery laters. Please guys,help me figure it out.

What does BBS say under "Process"?
Also, check the built-in process manager: Long-press the home button and click the pie chart. Switch to the first tab.
Is there an app where the CPU percentage changes even though the app should be sleeping and steady at 0.00%? I see that quite frequently. Mostly by the stock browser and the XDA premium app. Thats how I found the worst ones

I think the op has got some reason to worry.
Other than that suicide is not recommended.
