Galaxy Nexus spending too much time awake?

I've installed BetterBatteryStats a few weeks ago and have been monitoring constantly my battery life. What I've noticed is that my phone is spending too much time awake, sometimes almost twice the time the screen is on. I've tried different AOKP builds and CM nightlies both with stock kernel or franco's, but I always get the same wakelocks anyway. Of course I always clean-flash ROMs, and restore only downloaded apps with Titanium Backup. I'm currently running latest CM9 nightly with franco.Kernel r133. The pics and log attached are a few days old but I was on the same rom and kernel I have now. Consider it's one of "the best days", battery wise, I had since I bought this phone. So you can imagine what it's like in the "bad days"! Hope I can get some advice on what's the problem with my phone not deep-sleeping! Thanks in advance

deep sleep is a function of the kernel i never had a problem with the stock cm9 kernel but i always recommend GLaDOS kernel. There are a lot of great kernels out there and Franco's which you are using is one of them. i however always get the best out of my phone with GLaDOS and i always come back to it. Just like i try all the roms and always come back to CM9.
give it a try you wont be dissappointed

His problem is not kernel related...
I just took a quick look at the log and it shows powermanager service has been keeping the phone awake for more than an hour...
Will check the log some more when i'm @home...

As stated in my first post I've been trying different ROMs and kernels always having the same result... I keep getting this powermanager wake lock and I have no idea why. Along with that I'm always having the *backup* partial wake lock. I know that its cause is the data (settings and passwords) backup on Google servers, but I can't see why it should keep my phone awake for so much time. There are many more wake locks in the log as well. I'm really getting pissed of it. I really can't figure out what the cause might be. I doubt it's ROM or kernel related since tons of people are sharing my current setup and are not experiencing my issues. Any help you might give is very appreciated

I have the same problem as you and have since day 1. I've kept logs and used BBS and others. I have similar wake locks to you. I've never been able to figure it out. My battery life is OK, but not as great as others have claimed. I typically lose 2-3% per hour. Yours isn't terrible. My advice is to just try to forget about it. I'm convinced its a hardware thing that some phones have.

+1 to glados kernel. I've tried many kernels and always come back to this as it gives the best performance and battery life for me.
I used to have the powermanager service drain with Franco too but after a wipe and installed glados kernel battery went from **** to awesome.
Next time when u do a clean install try not to install too many apps at one go. Then test the battery drain periodically.

I would say its a trial and error thing. Try different rom and kernel combos to find out which one works best for you. Mine loses 1% of battery every 3-4 hrs of idle in wifi and that is with everything sync on. If I had 2-3% drain per hr, which I had before and its because of the powermanager service too, I would do whatever it takes to hunt down the cause of the drain.

I have the same issue as well. Is there a specific app or service in background running and drain the battery? I cannot figure it out. Will Google fix this issue in coming patch?
Thank you.

Guess I'll try with other kernels then. There should be a new CM9 nightly soon. Once it's released I'll flash it keeping the stock kernel and test it for a few days. Let's see if that will solve my problem. Otherwise there's plenty of other ROM+kernel combos left to try Glad I bought my Nexus! There's a huge developer community so that I never run out of options when encountering issues However if any of you might help me resolve this issue in the meantime I'd be very glad

I have tried so many combos although I haven't tried glados' kernel. That power manager service is really what I think is killing my battery life. The crazy thing is that I have a thunderbolt that I mess with. I keep it in airplane mode with wifi on and pretty much the same apps loaded as my gnex. With that I lose about 1%/6hrs. I wish I could figure out what's causing the power manger drain. It seems like there are a bunch of wifi related kernel wake locks associated with it. It would be great if there was an app that showed the exact times of the different wake locks and what programs are associated with them. Anyway, I appreciate everyone's help.

So I flashed latest nightly last night and I'm now on stock CM9 kernel... But the powermanager wake lock still persists... Left my battery at 92% while I was at work with wifi on. I went out for 20 mins with 3g on. In that little time my phone has lost 10% of battery all because powermanager service was running. Do you think it could be related to poor signal on 3g network?

Would a catlog show what's calling the PM API, keeping it awake for so long?

[Q] CM9 Battery Drain

I just wanted to start off by thanking drk.hd and invisiblek for all of their hard work on the ROM and I love it. However there is a problem that I got with the latest build and I can't post in that thread because of the 10 post requirement. With that said, I have been getting massive battery drain overnight the past 2 nights and I was wondering if anyone knows a way to fix that. Last night I went from 67% down to 14% and the night before was even worse, 74% down to 4%. Does anyone know a way to fix that? It's the same problem I had with AOKP and Abduction and I didn't have that problem with the previous CM9 builds. Any help is greatly appreciated.

I forgot to add my kernel. I'm using the incredikernel hwa beta 2 running on smartassv2 with 128 min and 1113 max.

Use betterbatterystats or badass battery monitor to see if something is keeping your phone awake.

Also, you could start by turning off wifi, gps, and bluetooth when you dont need them.

I do have those off. I actually had no problem on build 8 and I had amazing battery life and I've been using it the exact same way. I flashed over build 8 with 9 and then I started getting this massive battery drain over night. Weird thing is that it doesn't happen during the day only when the phone is idle for a long period of time.

Thanks for the response Tiny. Unfortunately, both of those apps are freezing up my phone and forcing a reboot.

I just resorted to a full wipe and hopefully that works out. Will report back tomorrow.

If they are freezing your phone there are other problems. Since you said you just wiped or will wipe hopefully that will fix it but it won't tell why.

You're right Tiny. After the wipe it seems to be back to a normal battery drain again as in build 8. The real test will come tomorrow though when I wake up. And the weird thing is that the apps work now after the full wipe. I still have a nandroid backup of the build 8 I flashed over if you want to do some tests with it to see what might have gone wrong.

Ok so it seemed that it was one of the apps that made my battery drain like crazy. I installed badass battery monitor again because I had a 12% drain in an hour at one point with it being idle with the screen taking up 40% of the usage. I uninstalled the last app that I installed which was the Videocam Illusion and I got only an 11% drain over night so it seemed like that fixed it.

[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?

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 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.

Help Battery Life

I have been stressing myself out about this for over a week, trying different things, buying new batteries trying new chargers, changing roms.
Turning so many things off basically making my phone into a dumbphone to try to figure out why my battery life is so bad. Could it be I just have a bad phone and need a new one??
I had a Galaxy S3 gave it to my GF, never turned any sync services off and I am able to get 20+ hours with that phone, this phone is HORRIBLE.
I was stock getting about 5 hours before dead battery (phone would get real warm- battery stats showing 33C+).
So I rooted and took it back to an LJC rom (4.1.1). Tried different modems, kernals, files tweaks with root explorer.
I bought BBS, a battery calibrator from the market and still cant see any problems that would do this?

last picture......
Should I just take it into Sprint and get a replacement???

Also try uninstalling and reinstalling facebook. My girlfriend's phone (GS3, not a note) went from 8 hours to probably 14 hours just by using the mobile web version of facebook instead of the the app. Facebook is atrocious at making apps.
But it really does sound like you got a lemon here, I'd get a replacement from Sprint. I don't think I could kill my battery in under 10 hours unless I was playing a game non-stop. My phone is completely stock.

I will uninstall Facebook, and test it out. Thanks!

OP. Your problem is not your ROM or anything else. Jeeze people.
Those partial wakelocks are PURELY from Google Now and the wifi/network based location. Either turn off Google Now, or turn off network-based-locating and those partial wakelocks will disappear....I'd also wager you have Sprint Connection Optimizer still running causing your phone to hangup trying to find a network conenction.

My battery took a good hite when I updated to 4.1.2 used to get 20+ hrs with 7+ screen time now I get about 14-15 with 4-5 hrs screen time

Based on your first pictures, your status bar, and the amount of awake time your phone is showing I'm guessing a couple of things. Do you have a phone signal where you spend most of your day? If my awake bar was solid like yours I wouldn't have a battery after 7 hours either. I would backup everything and do a full wipe / clean install and run the phone a day or so.

What of the borderline useless bells and whistles do you have enabled? I.e. face recognition/unlock, auto-brightness, SPen battery saver etc? Things like battery savers unsurprisingly don't help so i'd nix it as it is only wasting battery.

Meh. On this device I always aim for getting 10%/ battery usage per hour of screen-on-time on TouchWiz ROMs, and a fraction of a percent per hour in screen-off....something is burning battery here, and it is probably a system setting.

No face recognition/unlock, auto brightness is enabled, but with that little screen time does it really matter? No SPen battery savor. Thanks for the suggestions.

The thing is, I have a Galaxy S3... The Note II is setup no different then that, settings or otherwise. I am trying all of these suggestions, but why did I not have to turn any of these off on my S3?? Same service area obviously. I took the Galaxy S3 off the charger last night at 100%. Put a new battery in the Note II so it was at 100%. Let them both sit on the counter for 1 hour. S3 had 98%, Note II was at 87%... No calls no texting, no screen time. It is so fustrating! I have had my fair share of battery tweaking with previous phones (HTC EVO, HTC hero). It seems something isn't right. I had problems with stock rom, that is why I rooted so quick, to try a different ROM.
If the wipe does not work I will try to get Sprint to get me a replacement, was hoping the get this figured out before I fly to Florida for a week. Good thing I have extra batteries.

I would get a replacement. You should not have to turn off all thr features to get decent battery that defeats the purpose of having a smartphone.

I recommend having Sprint check it out for you and then buying Ds battery saver pro!!!

Bought Ds Battery savor. Charged phone to 100% put it in airplane mode went to bed at 11pm (phone at 100%), woke up at 7am and it was at 8% Fail! 0 screen time, 0 talking, zero everything and lost charge in a little over 8 hours! Going to use it in florida the next week, with my extra batteries and most likely going to return when i get back
Thanks All for your suggestions!

Has anyone disabled samsung push service. If not does it drain battery I have had it disabled since I bought the phone because I never use samsung chaton or other aops **** that but I want to start to use Chaton but not if push services has a big affect on battery.
