[Q] CM9 Battery Drain - Droid Incredible Q&A, Help & Troubleshooting

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.

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.
Sent from my Galaxy Nexus using Tapatalk 2
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] 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).
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.

[Q] Battery Drain Issues

Okay, so I am getting pretty bad battery drain whenever I use my phone. The phone goes into deep sleep just fine, and wakelocks don't seem to be an issue. Whenever I use any app though, the battery drains very quickly. Now obviously using the device will make the battery drain faster than it would when it's asleep, but I'm talking about losing 2-3% with only playing 2 minutes of Scrabble or checking a news feed for less than 3 minutes. My screen is on half brightness, but it's only been a week since this has really been noticeable.
I'm not sure if my battery is getting worse or something (although I try to not overcharge it and let it get to around 50% which I don't see why that would be an issue) or this is just an illusion and it's been happening the whole time.
Has anyone found any solutions or ideas to help conserve battery?
I'm stock, nonrooted, running the latest update. I never have any sync or push notifications active. I keep NFC on but I've had that on since day 1 and didn't seem to be an issue before. I restrict background data for the Play Store (tried that yesterday but didn't seem to help much), brightness is always around halfway, and I am using JuiceDefender pro. I have the Amazon App Store installed which I've considered to be an issue, but haven't seen many people complain about it recently and it doesn't seem to report anything on BetterBatteryStats.
Bump? =\
I've been experiencing the same problem as you recently. I'm going to backup and format EVERYTHING and odin back to stock and see if that'll help.
I have a feeling it has something to do with my SD card.

Hmm I didn't think of that. I have an SD card as well but I've had it for quite a while so I'm not positive if that's causing it.
Tell me if ODINing it back to stock actually does something. I believe that the battery itself may be causing the issues though, but I'm not sure.
...So there's only one other person which these issues? What am I doing wrong?
I hate to keep bumping this thread but I am literally only getting 3 hours of screen on time when I'm on airplane mode and am at 20% brightness.
Sent from my Sprint Galaxy S III
For the moment, my battery seems to be doing better. The only reason I wiped out my SD card was because my phone started getting hot at the bottom when listening to music from my 32GB SD card, so I thought it was some sort of corrupt file my phone kept trying to read and drained the battery

Sounds like something is eating up your battery. Try downloading BetterBatteryStats app. Fully charge the phone, unplug it and leave it for a while (about 1 hour). Then open the app to see what exactly is eating up your battery. You could post the BBS screenshots so we could help. Hope it works out for you.
EDIT: Besides that, you should post more info. Were you using the phone (playing games, browsing, videos) during those 3 hours or it was idle?
I noticed the same thing happening to me once, it turned out to be picasa trying to sync, using my google ID, but I don't use picasa. I was seeing 50-60% drain in four hours while idle. Check your sync settings.
When it happened it showed android system was using over 60%, battery.
I was having this issue. I could charge my phone to 100% unplug and go to sleep and 8 hours later it would be at like 10% i tried everything i mean everything even tried airplane mode it still drained. Put a custom jelly bean rom on it. Now my battery lasts all day. I just cant wait for

For me battery has been great but a few times i noticed its gets very hot and when i checked the CPU both cores were lit up at max speed draining my battery, after some googling a found this thread which explains the gsiff daemon is the culprit after a hot reboot.
No one has found what the gsiff daemon is for or what causes the ho reboot, but the solution is just use root explorer and rename the daemon so it does not run.
Have all of you having trouble with battery drain still tried looking at the term "deep sleep"? You can check that with an app called cpu spy. If your having that issue with the phone not deep sleeping, report back and i will post some ideas.
With those who do say they have deep sleep issues, post the ROM, and kernel you are on.

so lately i noticed my battery dieing super fast. the only thing i can think of it since att expanded lte in my area i basically get lte everywhere now and since then my cell standby is at 60% or higher my phone lasts about 6 to 8 hours now its very annoying... before lte it lasted a ton longer it could be a coincidence but its very frustrating if this is the cause because its pretty ridiculous
Post some screenshots of the battery so we can see more of what's going on.
If you flashed multiple ROMs on low battery then you may need to recalibrate. I did it with my GS3 and I wish I would have known about it when I had the S and S2. Download the BatteryCalibration app from the market and follow the instructions on it. I noticed I was losing battery life bad, but after this I got it back up to stock levels which is amazing.

I have faced the similar issue as your. After 3 days of constant inspection with various apps I figured out the process causing this problem.
Go to developer options and click on show cpu usage. If the top process is "gsiff daemon" then you have found the culprit. Download system tuner and kill the process and you can see that the cpu usage will go back to normal and your phone will deep sleep afterwards. :angel:

[Q] Cell Standby Battery Drain

Hi guys. A couple days ago I got a replacement GNEX from Verizon. I unlocked it and rooted it, threw Muzzy's rom on it.
Yesterday at work I had all I could do to keep it charged all day, it was draining the battery at about 20% an hour. So last night I tried a different battery, no change. So a couple hours before bed I downloaded the factory image, and wiped the phone clean and reflashed the stock image. I logged in with my account, put no apps on it, charged it to full then when I went to bed unplugged it with a full charge.
6 hours later I get up and its at 41%. The phone has been on wifi all night, no apps other than what comes with the factory image, the only things I have syncing are gmail, contacts and calendar. Google Now is off, all location services are off. The culprit when I look at battery stats, Cell Standby used 95% of the battery.
I'm at a loss, I can't have a phone draining that fast for no reason. I've been searching but I can't seem to find a fix or reason for this. As I said, there's no apps but the google apps. Does anybody have any idea? Should I try flashing the stock image again?
Any help is appreciated. Thanks.
What's your time without signal?
Switch to CDMA only and see if that alleviates the issue. If it does, odds are you have a defective LTE radio.

When viewing your battery usage in settings, tap cell standby for more info. You can also tap on the graph at the top of the screen to get a another bar graph showing various usages and wakes.

Weird I did that and it didn't show it before. Anyway, 0% time without signal.
I switched to CDMA only and in 15 minutes lost 5% not using the phone. According to gsam the screen was still half that and in apps android system is the top hitter. Radio was only 4.2%.
If any of that helps.

I was running Franco yesterday. I'm going to try re-flashing the radio now and throw another rom on it.

the most battery saving combo (in my opinion...an in the opinion of a lot of other users) is the Rasbeanjelly Rom with the Trinity Kernel.
i always get 4hrs+ displaytime clocked at 1300MHz. And the phne feels super super smooth. you should give it a try if you have time

Thanks, I'll give it a try.
I guess the big issue I have is that I'm fine with the battery draining while I'm using the phone, it should. But it shouldn't suck it down as fast or faster when I'm not using it.
Literally as I typed this I lost 3 percent......
