[Q] What's the fix to batter life problem, aokp b39/franco185? - Samsung Galaxy Nexus

Hi, guys! I'm still having a problem with the battery life on my Gnex. I'm using AOKP and Franco combination. Always updating the system whenever these two combos releases their latest bu still no gain on battery. Followed some tweaks on 'Custom Backlight Settings' BUT STILL NO IMPROVEMENT. I've been working on this for 2weeks working on the same combos because I don't know how to change ROM and Kernel coming from these two.
**xda won't allow posting outside links and so I can't show you the screenshots
**But I tried attaching the screenshots, please try to check below... Thanks in advance!

I Believe Nightly 185 had a new wifi driver which wasn't stable and drained alot of battery ... try flashing his stable builds

These screenshots don't mean anything without screen on time.
"Long is the way, and hard, that out of hell leads up to light."

As said above, screen on time please. Unless you're losing like 10% every hour, or don't get around 4 hours of screen on time (I get around 5, stock battery), then you're fine.

Okay. I guess this screenshot below is what you need. I hope this one is correct.
Also thanks for the responses, I'll try to flash either the Franco 181 or just change kernel I guess AFTER I HEAR ALL your insights.
**after seeing this screenshot below, what Franco kernel release do you guys suggest?
**Is radio probably affecting this as well? Because I didn't flash radio. Just Rom and kernel
**Should I try other kernels and what's the best fit for AOKP?

You're kinda correct. We need a screenshot when the battery is 2-3% and is about to die.
I get about an hour of screen time per 20% of battery however, so yours is draining about twice as fast. Still would like to see the correct set of screenshots tho.
Also, just fyi, I'm using Build 39 as well, but with Franco M4, and I get around 5 hours screen on time. Keep that in mind if we decide that the kernel is to blame.

Thanks! So, I'll just wait for my battery to drain (2 to 3%) then I'll post a screenshot again. I just flashed Franco Milestone 3 and will observe. If it still no go, I'll flash M4 LOL ... Then would probably switch to diff. ROM and Kernel combo if all fails

Oh, I don't have wifi at home. SO whenever I install apk, copy pictures/videos or even posting screenshots like today, I plug in the usb chord and it automatically charges the phone.
But if I don't connect my phone to my PC and use the phone moderately, the phone get's low battery pretty fast, like after equivalent is 3mins= 1% ...
Someone suggested air kernel. I think I'm gonna try that one and see the result.

Well if you're doing that it's hard to get a good grasp on how your battery is performing. You should go a full cycle without hooking it up to your pc and then post your results.

I agree and I will post maybe tomorrow. But in the meantime, what kernel do you suggest for battery life? I got my eyes on Lean kernel. Changing ROM would probably be the last thing I would do IF changing kernel won't still work.

I don't remember my results but I did get great battery life on leankernel. Currently using Franco's milestone 4 and still getting pretty decent battery life.

First, post correct stats (no charging in between), and then let's discuss the future.

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?

Battery drain on clean Rom installs.

The last few nights, I have tried a few different JB Roms. All with the same results. My GNex has a full charge before I go to bed, I wake to my phone telling me to charge it 8 hours later. With NO wifi or network data on. This can't be normal.
The roms:
ASCENT 3.0
Jelly Belly 4.0
New Unofficial Cyanogen Release.
No extra apps installed. Purely stock.
Tonight, I'll try it in airplane mode, and see if my network coverage is what's draining the battery. But for the most part I'm never without a signal.
Any ideas or ways I can see if the battery is just bad?
Also, what would the current Verizon radios be? I believe mine are up to date, but I guess that could be an issue if it is indeed my network signal being dropped.
Im on the 07/27 fitsugly cm10 rom with r225 franco kernel and for some reason my battery life has gone through the roof, after 30 hours of being on the battery is still at 56%. Granted im not using it much now but still i've never seen this type of battery life before. Overnight the battery dropped maybe 4% at best, wifi is always on and its fetching emails.
How odd have you tried charging up and resetting the battery stats ? May help

I think I tried that ROM before, not sure if its just for maguro. I have a Verizon toro.

If you don't need the higher clocked gpu speeds then just stick with the 384mhz kernel.

Try better battery stats... I am on gsm nexus.
I tried jelly belly, minco , paranoid android, and xenonHD plus bigxies stock. I've used Francisco Francos kernel on bigxies and that gave good battery life but the others all burned cpu and battery, specifically via Android.mediascanningservice. and maps.
Right now I am back to stock 4.1.1 rooted courtesy of rom toolkit and with better battery stats and cpu spy I have a cool phone.
One thing you should be aware of is if you have a lot of media on your phone the scanning service can take a long time to run and calm down. I I upgraded my bosses razr to ICS and his phone took all night to update I guess he has lots of music on it...
To increase battery life you can install titanium backup and freeze maps, and wallet when I not in use. You can install rescan media from the app store and trunk off media scanning service. Or just buy a bigger battery.
This is not a knock on the custom roms. The rom teams mentioned above they are all awesome and are the reason us crackflashers have so much fun. I have learned lots from this experience and have a better grasp on how my phone works due to the efforts of these devs. For now I am sticking with stock... I'm sure I'll be flashing again soon.
You can never judge a ROM on battery life within a day. Every ROM I flash gets bad battery on the first cycle and most the time even the second cycle. You really have to stick with a ROM/kernel combination for at least a few days to be able to judge battery life. It may just be a placebo effect but I use a battery calibration app each time I flash

Resetting battery stats accomplishes nothing related to battery life or reported percentage. It's been debunked some time back by Google.

Best ROM for Battery and Data Use?

I am sure this has been asked, but I really need some help with this. I am using fully 4.1.1 STOCK and I do use the data on my phone quite a bit, but I don't see how after 6 hours, my phone is completely dead after a full charge. Screen on time was roughly an hour and a half! What is the BEST ROM with the best Kernel even, for battery life and extensive use of data?
The max I could get waas 2 hours screen on time, 3G really hurts your battery, I don'think theres anything that can change that
stock is always best.

No I don't think so. Are you using the Verizon or GSM version. There must be something with your phone or the settings, possibly a wake lock issue. With the GSM version and 2000mAh battery I can pull 3-4 hours of on screen time, using roms like AOKP and Franco Kernel. I turn off data, wifi, gps and bluetooth until I need them.
Can you go into Settings -> Battery an take a screenshot. Then press on the "battery graph" to reveal the history details screen and take another screenshot.
Not sure if it work with stock, but holding the Power + Volume down button should take a screenshot.
Every bodies phone acts different with certain ROM and kernel combinations I have had good luck with lean kernel but that doesn't neccassarily mean you will

For your display brightness, you may want to install Screen Filter. Its in the market. Especially without having to tinker with the display settings it lets you dim it down even lower than the lowest setting. Also great for movie viewing in a low/no light setting.
I think this requires root, but you should try Better Battery Stats, select partial wake locks since charged, and see what the culprit is.
CPU spy would also be a good one to see what frequencies your cpu is running on the most.
I'm currently on liquid beta 1. It seems to hold battery quite well compared to cm10. I also use trinity kernel, and the TKT app.

[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.

I'm getting the complete opposite of u op
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.

Try wiping ur battery stats in cwm

I know that is supposedly a placebo, but in this case, something is clearly wrong. I'll give it a try.

[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.

Where do I find time without signal?

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......
