[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?

Kernel
I'm hoping its just running it a few charge cycles fixes the problem, because my battery meter is like a countdown clock right now.
I'm running 3.0.41-franco.Kernel-Milestone5.

I reccommend getting cpu sleeper. Its brillant and saves me tons of battery

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.

Sent from my Galaxy Nexus using xda premium

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).
I'm going to completely wipe and re-flash JB tonight, keeping the stock kernel this time, unless someone can help me out.

Did u flash francos kernel yet ?
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.

Battery draining at 1% every 2minutes, help!

Ok guys, so i got my replacement siedio 3800, and after charging it initially for 12hrs, after I got it. The battery issue is still here. When the phone is not on, or standby, it is fine, however while using it, the % ofbattery life just keeps dropping, 1% every 2minutes about I timed it and averaged it. I checked GSAM 29.5% is used by apps, i have only 3g enabled, no wifi, bt, or gps. Plz help me get this fixed, same problem was with the Razr maxx. I am using Bamf JB rom. About to throw the stupid phone lol!
And i do have full 3g/4g, but only 3g enabled, with good signal strength

if you're saying it happens on your maxx as well... you have a app burning your battery

Find the app
Delete non essential apps

god is the creation of people with nowhere left to turn

how do i find it? i am stock bamf jb , with gapps, thats all, and under battery, no apps are burning a lot, web browser was 6% was the most. and GSAM said only 29.5% of battery was apps

could it be google talk, or aim? i usually exit out of both when done. But google services is always on in running apps, but didnt want to disable, wasnt sure if that was for gmail. auto sync is off

What do you mean stock BAMF? BAMF is custom ROM and rooted... If you ARE rooted, easy. Download betterbatterystat from Play Store and see which app drains the battery the most.

is gsam the same type of app? It says apps are using 29.5% and browser is highest at 8%. I really dont want to pay $3 for the betterbatterystats

then go back to stock. if the problems happens on stock WITH NO APPS, then you have a bad battery.
if it doesnt happen, you have a crappy app somewhere.

If you don't wanna pay, you can still download it from xda. The dev offers the app for free for xda users.

How did you fix the issue? Also I disabled all extra apps so we will see. Otherwise does someone have a link to stock ROM image? Or another trick and tip

Hello. That is why people invented .apk files. Just download a .apk file. It is what everyone does.
Galaxy Nexus-codenameandroid rom

usually bad/rogue apps wont show up on those battery apps. I remember i restored app settings/etc for dolphin from 2.3 to ics and that was the cause. Removing data/cache and the app itself removed the battery drain.

Do a binary search of apps (install half of them, if it drains then the culprit is in that half, if not in the other half, etc etc).
Try to disable as much syncing as you can, and definitely disable instant upload.
Betterbatterystats apk from the thread that deeren linked to. cpuspy might also help.

imo you should perform a reset and start over.....its faster

I didn't.
Use WiFi when you can it what helps me. I am now on Affinity ROM and got 21.5 hours with 2 hours 45 minutes screen time. With the 2100 mAh battery. I am using the Glados kernel it came with and no tweaks to it.

Trying to track down a rogue application is hard work, do it only if you feel like you're up for it.
Apps with good reviews and comments don't usually cause such a problem but checking per app reviews/ratings will take you, I don't know, maybe till you grow old.
Best thing to do is to reset everything and start light, with only a few apps, then install another batch of apps if there is no problem with installation of previous batch, this way you can find the culprit.
Good luck.

OK well I am back to 100% stock like suggested and charged my battery 10-100% overnight. Still losing lots of battery. 13minutes cut me to 94%. So it was the rom after 3hrs of getting back to stock. This is also my second siedio 3800 battery. What's next?

Hi, after tons of persuasion, I've taken the plunge and enjoying my 5.5" note 2!
My question is how the LTE is holding up for you guys.....I have everything stock so far, but just noticed that the phone dropped about 2% in 10 mins on standby.

You must have an app that is eating battery. My Rogers Note 2 drops about 1% per hour in standby. Get GSM Battery app to see what is eating your battery.

Maps is possibly related to Google Now which continually polls your location.
EBay seems suspect.
I use BetterBatteryStats to check for wake locks.
I also found that the battery performance gradually improves over the first few charges. Same was true of the Galaxy Nexus.
Turning LTE off made very little difference to me. And generally I get about 36-48 hours on a charge.

Ive shut off google now already, but not sure why my maps app is waking this many times
Sent from my SGH-I317M using xda app-developers app

Chances are that Google's Location Service is constantly polling. Not sure what people mean by "turning Google Now off" but unchecking the Google's Location Service has helped reduce my maps wakelocks to perfectly normal behavior.

If you have the time, and really want to be sure, you can do a factory reset and then install only the basics and the few things you 100% know are not a problem. Then incrementally add stuff till you see the same problems.
Honestly, I don't know why people leave such a huge number of apps installed. There is not that much that you really use.

HTC one x battery life

Hi I've just recently decided to swap my xperia ray for a second hand HTC one x and unfortunately the battery life is horrid, under 4 hours and the battery is below half. 3g is on 24/7 and I didn't browse the internet for even a second , only text and call and I can't believe it, seriously considering taking this back unless somebody can convince me otherwise. All I use is the internet and calls and texts, and if it can't even handle those , then how am I going to be able to use the internet ..

are u using a custom rom ...? if not then say which base it is...3.14 oder 2.17 ...

You might try searching the forum, there are LOTs of battery related threads.
Install BetterBatteryStats (search here for it and how to use it), and check wakelocks and partial wakelocks, should tell you what is preventing the phone from entering deep sleep.

i like the battery life of my phone very much but also think, when you are using a custom rom, the rom and the kernel need to settle and i think, this take a time.. try one and give it 1-2 days, until you see the real battery draining

Came from Xperia arc myself, but wasn't expecting tremendous battery life, tbh. That said, there's virtually no drain in screen off on any stock based rom, so it evens out. Haven't tried aokp, cm10 or miui due to the pretty horrific battery life on the arc with them.

mine hox have nearly 1 year, but no better or worse battery performance. max 1 day :crying:

the battery life of the htc one x is an enigma to me (no other word can do justice to how much confusion it's causing)....I understand everyone uses their phone differently but the battery life shouldn't be all over the place as it is. My battery is lasting between 24 and 48 hours regularly with normal use i.e. normal everyday use on my one x, calls texts, camera, finding a place on maps while lost etc etc
screenshots attached.
I understand a lot of the problems are being caused by the phone not going into deep sleep. One of the ones I pinned it down to was if you go into Maps and check the location settings through there...i've turned them all off (and i still get correct google now information).
If someone wants to try that and then let us know what its like then that'd help everyone.

well not quite sure what you're doing with your phone - in that image, your mobile signal is only on for about half of the total time? did you have it in airplane mode or something?
my battery is pretty terrible - actually shocking the past few days. I can't even get through a full work day without it being down to <30%, which is only 9 hours or so. I've had power saver turned on all the time, too. I use it a bit for texts during the day and that's about it - no heavy data use. so I have no idea what's sapping it so heavily. it's quite bizarre. even if I try to micro-manage my data by turning it on only when I need it, I still get down to 40%.
this is on a stock ROM by the way. considering changing to a lighter weight custom ROM to see if that helps, as this is just ridiculous!

How much was your screen on time tho? I could just leave my phone doing nothing and have over 1day battery.
@op you could try the battery calibration. Charge phone till green light, once fully charged unplug and switch off the phone and charge again till green light now switch on and use phone.
You should now have better battery.

[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.

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
like someone in this thread already mention, turn off 3G when not use..Go to task manager & switch off all running background app..clear memory..Do it b4 u go to bed every night..Good luck!!

1st look seems like the blue bar is always on. Tap on the graph and see the breakdown further, whether is it awake due to screen on or not.

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

You've posted 11 minute old stats, post from a full charge cycle.

It would. Well, she wouldn't care as much anyway....

Well op is right.
I have wifi gps 3g sync always on with close to his usage and I get 3 days straight.
Lol.
Overnight 1% drain max 2%
I think the op has got some reason to worry.
Other than that suicide is not recommended.
