Horrible Battery Life for me

My phone has TERRIBLE battery life. In about one hour (on stanby with wifi or data on) my phone loses 10% battery without use.. Which is a 10 hour battery on stanby. I can BARELY make it through one day without my phone dying either. By the time i get home from school, my phone is down from 100% to 65-70% with VERY minimal usage. Then by 9:30pm my battery is down to 20% with moderate usage on wifi. I am running Beastmod 4.2 REMASTERED with whatever Kernal comes with it.. I have tried Juggernaut, Beastmod, Beastmod Remastered, Stock, unrooted, domination with no luck. Ive tried underclocking, over clocking, changing settings, brightness, different launchers and so forth. Still, i have no luck. Yes, i have calibrated my battery, and this is my second phone from T-Mobile (and 3rd battery) that has a short battery life. Can someone PLEASE help me with this. Thanks!
EDIT: Just typing this message i have lost 3% of my battery on wifi...

I really dont know what the general view on this is....but if you are flashing a lot you wont know the difference. You need to get through atleast a few full cycles to figure out if something has decent battery life. No ones phone is going to put out the same results. I have had a lot of bad results with ROMs people claim to be the best. Just try a rom + kernal combo, give it a week, see if things start improving, else flash something new the next weekend. Do proper wipes, restart your phone when its charged at 100% and go from there.

You leave GPS on? GPS is a drain even if you're not actively using it. Also try charging the phone to 100%, then drain the battery completely, then charge it back up to 100% with the phone off. I've found that usually greatly improves battery life.

Do a full wipe and flash macnut r1. I had similar problem as you until i flashed this rom, i think his kernel has the best batt life of them all and most stable for me. Worth a try

Sorry if this is a dumb question, but if i wipe my phone in Clockworkmod Recovery, wont it erase the ROM? Because that happened to me before. Thanks

Check Battery info. Is your phone awake even when the screen is off?

I leave it on lionheart governer with max 1,512 and min 192 and it works very well for me

Try this wipe your rom clean and dont install any apps just your emails and try it for a whole day maybe an app is eating your battery in the background.

Click the graph.
There should be a "Screen on" section and an "Awake" section. The two should be pretty similar. If you see a lot of Awake time even though the screen isn't on, it means you have a wakelock.

i dont know why battery saving programs like to kill your radio if your signal or battery is low......that's the whole point of having a cell phone!!

None of these "battery saving" apps work. And all the things they do can be done manually. If something has to run in the system to "save" battery... it uses battery attempting to save battery.

Well i notice that when i dont use JD i lose a good few hours on my battery.
JD does help when i ran W/O it on i went from 100% to 92% in 10 mins all i did was mess with some settings in the menu of the phone not JD.

task manager
I thought that's what the Task manager on the phone is for? I remember when I first got my phone at sprint they told me not to download any battery savers or task killers because they "bump heads" with the stock task manager. If I'm wrong please let me let me know.

No things have changed reason is they think that if you use the TW Task Manager it will kill thee battery app but if you know how to use either both for example Juice Defender has the option to stay in status bar so it won't be killed if you kill apps on the Task Manager, but why would you kill the app in the 1st place if you knew it saves battery.

Any results you say you get with these so called battery saving apps. Was because you were too lazy to do it manually. Had you done it manually you would have gotten much better "results."

I agree, and I am lazy, but I don't get better results doing it manually because I usually forget. My phone is a tool, I have enough important things to remember about rather then whether my wi-fi is on or not.
And if that fails, I always have my extra battery, or desk charger, or car charger etc. . .

One of the best things I have done to DRAMATICALLY increase my battery was to change the kernel, ROM and undervolt. I found the best combination for me was to use Shadowkernel v1.04, Legendary ROM and then manually change the voltage settings by about 10% or more.
I used to drain about 10% an hour on standby with wifi but now I'm down to about 1-3%. I drain about 6-10% an hour when I'm using the phone. The only problem I have is when I have a very bad signal, then my battery life goes down over 10% but I think I would have the same problem regardless of whether I modified my phone or not. I don't use any battery saver programs at all now.

[Q] Help! Flashed Jelly Bean, down to ~6hrs Standby Battery Life

I flashed Jellybean for my gnex this last weekend, and I've noticed a severely precipitous drop in battery life (15% in 90 min, 15 min screen on). I found this yesterday when my phone went completely dead after just 6 hours on idle, despite running some pretty severe power-saving options. I can literally see the battery draining as I took the screenshots to post.
Running 4.1.1 stock, Franco Kernel Version 5 (power save powermode), 2100 mAh battery - I tried to provide as much information as I can in the screenshots. The weird thing is that none of the information stands out as an obvious power-drain, its just falling for what I believe to be no good reason.
Please help!

First of all: congrats if providing such detailed information about your battery information! (I'm being serious, not sarcastic)
Secondly, have you tried running it with WiFi only to see if there's a difference? Also, you need to go through about 2-3 charge cycles before you have a good idea of our battery range.
Also, what kernel are you using?

CPU Sleep
Thanks! However, I'm already running on only one core, from a setting in Franco's app.
My problem is that there doesn't seem to be anything glaring that is draining my battery. Awake time is slightly more than I'd like, but not nearly enough to drain the battery at 10% an hour with the screen off.
And for the above poster, I have not tried running it with wifi only and no mobile data - wifi at my office is spotty, and I'd like the conditions I am testing it at to try to mirror how I would normally use my phone.

hmmm... did u try replacing the battery?

Battery
No - the battery worked just fine on ICS as of last Friday (28 hours standby charge). I would hope that flashing ROMs/Kernels would not actually damage it.
Thanks for trying to help - I'm really confused since all the ratios look comparable to people who get great battery life, but for some reason, just seem to suck about 5x more battery for me, so its impossible to pinpoint one specific culprit. I thought it was a mis-calibration, but apparently that is just a myth.

Let me start by saying that I am not an expert, but the following tips helped me. I agree with the WiFi and the detail you provided was great. I see that you are running 4G, this will eat up the battery. Your ROM may have a toggle for the 4G (LTE) and 3G (CDMA). If you have WiFi available I would use that. You may want to turn off the NFC (system setting>Wireless & Networks More....) unless you use google wallet or share screen alot. Also, I had horrible results with the Facebook app running in the background, which I have taken off my phone. I set a bookmark in dolphin browser instead of using the app.
If you are not seeing any improvements with in the next few battery cycles you may try wiping the battery stats in Recovery. The first ROM I flashed from stock my battery life was all over the map and wiping battery stats helped. I ran the same Franco Kernel and was getting 2.5 -3 hrs of screen time. Hope this helps.

also, get CpuSpy from the market, and see which speeds your cpu is using (or not using).

Not that this will help software issues but Sprint is giving away a free 2100Mah extended battery with the door. You just have to pay for the shipping. No scam at all, I think they know that they have a glitchy piece of product and need to help calm us down. Just call telesales and tell them you own a Gnex.

CPU Speeds
Almost exclusively at 384 or 729 mHz, capped at 1026.

So that means that the CPU isn't going into deep sleep, which is an issue.
All I can suggest is reflash with a full wipe, and reinstall the apps you can, and slowly weed out any rogue apps that could be causing said issue.

Deep Sleep
Sorry, I meant that when awake, the vast majority of the clock speeds are 384 and 729. I am in deep sleep approximately 75% of the time.
If no solution comes up in this thread, I will try re-flashing to stock JB/stock JB kernel tomorrow night to see if it just needed a few recharge cycles to stabilize, and if not, if wiping/reinstalling helps.

Yeah, that seems to be the general experience here. My phone is down to ~28% since the OP. Again, the proportions in which things are draining power are correct, they are just doing it too quickly (1% per minute of screen time).

Sent from my Galaxy Nexus using xda premium

Yes - every process/screen is drawing the typical percentage of power use (~50% screen, 8% Phone Idle, 8% cell standby), but the battery is draining 4x faster than it should. Francos app shows me running at completely standard voltage, and I'm on the powersave mode. I think it must be a battery indicator/stats issue, otherwise the proportions would be all off.

Read the OP and look at his screenshot.
None of what you recommended will effect excessive "Android OS" battery drain. None of it. All the items you recommend changing show up under the system battery readout under other discrete names. So no, turning off wireless connectivity or dimming the screen etc will not alter the OP battery life substantially. And turning off your cellphone negates the entire point of having a cellphone nvm a smartphone. All those measures are bandaids for underlying issues not actually solveable with a bandaid.
So yes. Really.

Well I don't know what to say to this. I know what my battery stats were and I wipe them (and I continue to wipe them) daily. Maybe my nexus is special. Come to think of it, it has had some problems before. Maybe this is a way for it to make up to me

Interesting things happen when you wipe the cache. This is from my Nexus 7 during Video playback. Seem like the battery consumption gets attributed differently.
Exactly the same setting, ROM & Kernel, both cases I use MX Player Pro with H/W+ accleration to playback 720p videos. Only difference is in first case Screen battery consumption 83.5%, the other 57.7%.

Get Elemental X 1.8 and run it at stock clocks (1.5Ghz CPU/400mhz GPU) will probably give you the best battery life. If adjusting a lot of settings when installing a kernel is a hassle to you, get Bulletproof 1.3 instead. Bulletproof have the same developer(flar2) as Elemental X, it is basically a developer optimized version of Elemental X running stock clocks & optimized for Battery life.

I wipe them because like I said before, the file can get messed up when switching ROMS. It got messed up on my LG phone before so I wipe just to be thorough.

Thought so. Unclear answer as you don't have anything conclusive to say.
Just keep on wiping, it's highly recommended :good:
