Hi guys,
I recently switched to CM 10 (Android 4.1.2) and the battery life is significantly lower than what I had on the stock ROM and the new Sense UI... I guess.
My phone won't run longer than 10-15 hours a day with normal usage, which means Wi-fi and 3G always on, screen on automatic brightness being used for about 1 hour in total (for one charge). However Android OS, Cell Standby and Phone Idle still account for the most battery usage, which I find weird. I have no wakelocks and my device goes to deep sleep when not used.
Is this normal behavior with the new Cyanogenmod and Jellybean or are my expectations too high? I already read most threads concerning battery life, but most of them discuss problems such as wakelocks or similar issues. My question relates to the normal behavior of CM 10.
I am grateful for all replies on the matter or personal experiences.
It's known that CM10 battery life is worse than stock JB. You can try different kernels and different governors, but it's a trade-off between life and performance.

I don't understand, I thought that CM is stripped out of unnecessary background processes and apps. As long as I'm not using any CPU or GPU intensive apps like games it should consume less battery than the stock ROM. Is there something I'm missing?
Maybe the updated kernel and drivers give better power effeciency. When the JB kernel source is released, hopefully CM10 and other AOSP ROMs will also improve.
You were saying about on screen time?

CM 10 really uses a lot of battery but of you could switch off wifi and 3g when not using, and clearing all the apps frequently in the recent menu may help... My battery then lasts from about the start of the day till night though the batterys now quite old.

i got a weird battery life yesterday, i was walking from work to home, i started watching videos on youtube, looked at the battery, 31%, after few videos looked again, still 31%, i walked 41 mins with a total of 9% of battery drain, i also played a game for about 25 mins, it was a really battery life.

That's pretty much my battery life as well. Regarding age, I'm really concerned, as I'm not able to open the phone and just replace it. But I guess that much better smartphones will come along before I consider getting a new battery and it won't be worth it any more.

I get that sometimes as well. I pick up the phone a couple of times and the battery is always at, say, 50%. Then, a couple of hours later I read a message and it suddenly jumps to 41 or lower. But from what I've read that's normal and no cause of concern.

I heard what causes the CM10 to have such an awful battery life is something that was supposed to save power when you lock your phone [Which is normally quiet often] and actually causes it to depelt, so it obvoiusly doesn't affect screen time
CM10 is a horrible ROM, get something else... I used LiquidSmooth for a while, it's a great ROM
Now running ParanoidAndroid 2.53
Btw, Stock ROM had a wonderful battery life, I only realize that now ... lots of ROMs can't reach that much

That's exactly what I did, flashed the old RUU and installed all updates. I don't know how the guys from HTC managed to do it, but the battery life on Android 4.1.1 and Sense 4+ is AMAZING. I easily get 24 hours with normal usage, over 2 days if I'm really careful.
This is what I got during a night sleep with cm 10.
I installed it yesterday so its kinda new tot me. What causes this?

Probably some nasty wakelocks. Install with wipe/factory reset if you didn't so already. Then try betterbatterystats (search xda) to find out what is causing wakelocks.
Hi! Guys, Well I bought my Note 2 in November 2012 with Multi Window update already Installed. Everything was So smooth and awesome until the Christmas update in India. My battery started draining comparatively fast but still not a huge change. But handset became little slow. That I consider Negligible. But then come the Jan update which I feel was quickly done to rectify that "root permission by default issue" like in S3. And after that am facing Issues like fast battery drain like previously when I used to sleep my battery drop by 1% only but for same amount of time when I check on waking up it had gone down by 7-8% and haven't installed any new apps so far.
But the biggest issue I face is that Note 2 won't charge sometimes then I have to restart my mobile and then it charges again and it happens quite often. Like I will face this 3-4 times in between 10 cycles of charging.
My Note 2 is not rooted for now.
Also a issue I have noticed that sometimes my camera images becomes corrupt on its own. This happened only 2 times though.
So, guys do share your advice/views on this.
Thanks
Also I have noticed that some times blue led blinks on its own. without any notification. And Smart alert doesn't go off, faced this rarely though.

You can TRY flash the latest FIRMWARE using ODIN... I'm not sure whether it will solve the battery drain issue but you cab try, but I personally think it's not too big difference...
For the battery drain issue, here is my suggestions:
1. Flash CUSTOM KERNEL, do undervolting your device, which I believe will significantly reduce the power usage...
2. Try use ONE POWER GUARD apk, I optimize the kernel and CPU, and other stuffs (Wi-Fi, 3G...) It's available in Google Play.
3. (I think you really need this if your battery is behaving as you mentioned) Do battery calibration, download BATTERY CALIBRATION in Google Play, charge your phone to 100%, open the app and tap BATTERY CALIBRATION. After that drain your battery until it switch off automatically, and charge your phone to 100% again in off mode...
And I'm so sorry to tell you that you need ROOT access then you only can try these solutions...
I also had battery drain issue before, but I found out that if you use all my suggestions, the battery life does INCREASE!
I flashed Perseus Kernel and undervolted my device using SET CPU... Battery drains about 6-8% in an hour with my Wi-Fi ON, Auto Brightness, and without turning off the screen to surf the WEB!
After that, I found out that my battery also drains about 7-10% after a whole night deep sleep, when I wake up in the morning.
I found the second solution, which is using the ONE POWER GUARD. Now, the battery life IMPROVES EVEN MORE! Now when I wake up to check my device, a whole night sleep is just draining 2-3% the most!
Thirdly, I accidentally found the Battery Calibration app in the Google Play...
I tried that but no difference, since you only need to use it when your battery starts to have problem (Others comment)
You can try this, I saw many good feetbacks from many users that it helps...
Now, I open my Wi-Fi all the time with Auto Brightness. I enjoy my music, video, web ever day. I finished charge my phone in 9 am yesterday, and now, I still have 51% to use XDA app to write this post Amazing isn't it!
ROOT YOUR PHONE, IT DEFINITELY WORTH TO SAVE YOUR BATTERY BY USING THESE SOLUTIONS... (My Opinion)
TRY THEM OUT BRO! GOOD LUCK

Thanks a lot for your suggestions.Will definitely gonna try these. And will surely root my phone once I get proper time to perform this ..
Yep I also think that these are cause of new kernel which samsung released hurriedly.
Will Contact Samsung and see what they gonna say.
And I checked my battery drain today with wifi & 3g off, Screen rotation off, sync disabled,location disabled,All motion disabled, pen detection battery save on but still ate my 5% of battery that too in sleep mode. Samsung's New updates have lot of bugs.
will root my mobile and will see how it performs. Thanks again for your valuable suggestion.
Ps;- I have also added some forgotten issues in my original post.

A lot of people complain of battery drain with their latest updates. I'm personally not too happy with it, but my device still lasts a whole day. I'll give Samsung another update to fix the issue. If they don't, I'm going back to 4.1.1 because I never had any issues there.
I've done a hard reset and nothing. Next time I'll try clearing all data and everything off of my storage and we'll see. Hopefully Samsung will fix this.

Indeed Samsung's new update has numerous bugs, hope they will fix it soon. 4.1.1 was Flawless.
And I doubt that clearing all the data will help as battery drain will be related to the new kernel and OS.
Let's see when will Samsung gonna release there new update to fix these issues.
I flashed the new MA6 French firmware, seems many MODs and Custom ROMs are released/updated based on this firmware...
I will see how it goes, I still using Perseus kernel, and ONE POWER GUARD.
So far, the results are not sure because now I have only tested it for 2 hours...
Hope it doesn't drain much battery... :laugh:

Maybe you can state all of your issues, I will try to help :victory:
I'm always sensitive to my device, every time when I feel that battery drains faster than before, I will always find out what was the problem that caused battery drains...
It's kinna pain in the ass to see battery drops faster than the first time I used the device.
So far, those suggestions that I've provided are my "BEST" solutions. (My opinion)
I will also continue to monitor my device after flashed the new MA6 French firmware...
I will see how is the results and share my experiences to you all (For those who would like to listen... If I am wrong, please don't blame me and I'm sorry)

Same with me, it pinches me a lot to see my battery draining faster than before. And even I try to keep Hawk's eye on what's gulping my battery but so far I ll only blame it on new official samsung kernels.
But Well I guess Samsung has heard the cries of people and today I received two updates(OTA) mentioning Stability update. Hope this fixes this battery drain and other bugs. Also, now they included Google Play Music App in the update.
And after 4 hours of the update, battery life, I feel that it still draining quite fast but will test it in 2-3 days to be sure. Will update after few days of usage.
And thanks again for taking time to share your suggestions
Looks like the update was kinda dissapointed... It is quite battery draining after a day...
But I did try battery calibration as my solution, looks like is kinna sweet.
I charged my phone until 100% full this morning 11am and did battery calibration, now I still have 72% after listening music, surfing facebook, instagram, and twitter, with Wi-Fi on all the time and Auto Brightness on...
Anyone tried anything else?

Im about to open thread but I saw yours so I decided to put my own issue.
I just upgraded my sofware from 4.1.1 to 4.1.2 France rom. Factory wipe before and after upgrade and first thing noted battery drain. I would specifically note SCREEN ON is eating my battery. 19 hours max i could get which comparing to old rom was day and half with exact same apps and settings.Who faced the same thing and who managed to resolve it?

Yep new updates doesn't resolve battery drain issue very much but its still better than before. During my sleep for around 8 hours, battery drain was just 2%, I was so happy but during normal usage, I still feel battery drain is little on higher side. I guess new updates do increase standby time but while on load it just doesn't performs like it used to be on 4.1.1.
That's sweet, you manage to get a lot of juice by those calibration. Currently Charging my phone and will see how it performs after a full charge cycle.

Well, 4.1.2 do drains a lot of juice from battery when compared to 4.1.1. Almost every Note2 has been plagued with this after updating to 4.1.2. That's kinda shame for Samsung that their new updates are battery juice guzzler.
And to resolve this battery drain issue you can wait for samsung to fix this in new updates or you can root and then install custom kernels and roms. And also please go through takumibunta's posts above, He shared very nice points to resolve battery drain issue.
have any of the ones who updated checked for sensors of movement and like that? i updated to avoid the SDS but after the first day I noticed that my phone was draining faster. I checked some things and some of them have been changed with the update (movement sensors is the only one that i can remember now) and now it last the same than before with some apps more such as xda app which it is said that drains also some battery
Hope it was just that the issue good luck!

Hi bro, I did some research before. 8 out of 10 people suggested do a battery calibration after flashing a new ROM. Well I tried and I think the results are good. I upgraded/flashed my firmwares four times since my first purchase. And I noticed it ate my battery when I flash a new firmware.
I did a battery calibration, it managed to hold more than 24 hours. I'm sorry I can't share my battery stats now because I just did calibration again to monitor my battery again so that I can ensure the accurate and 'real' result.
I'll keep you posted, let's see how the device go. Anyway, I still using a custom Kernel, did under-volt and using the ONE POWER GUARD app...
And 1 question, is your phone using all stock settings, ROM, and KERNEL??

Oh yeah I almost forgot to share with you guys.
I found an app called Android Tweaker. It is free from market. But I managed to get a PRO versions which contains full functions.
For details just refer the Google Play's descriptions...
Back to topic, I used this app to do some tweaks on the battery section which are increasing the Wi-Fi scan interval and Increase Deep Sleep Battery Life...
I will see is it able to push my battery saving 'limit' even LOWER. Now I'm still charging my phone. I will wipe my battery stats and monitor again... It takes time, and I hope it will show more significant result of maintaining battery life.
Try this app with CAUTION! It might cause BOOTLOOP or get STUCK at Samsung logo!
DO A NANDROID BACKUP BEFORE USING THIS APP! JUST IN CASE. I HAVE WARNED YOU ALL...
See you guys soon...

Lets first all agree in one thing to narrow down the source of the drainage. Is it the SCREEN ON is the eating your battery?
To answer your question im in stock rom and stock kernal with cf root only.
I know there are methods by using custom kernals and undervolting and supported apps.
Honestly I prefer to stable my stock rom and kernal battery usage first to last my battery more than 24 hours. So basically I like to work on stock because the majorty of the phones users are stock.
One thing I can try is battery calibration. Can you tell me the process?

Ok.
There is 2 options for your case.
Since you are using stock ROM & KERNEL, with ROOT access,
First option, I suggest you to use the ONE POWER GUARD app... The latest version is stable and there is a battery calibration function in the options.
Second option, download 'battery calibration' in the Google Play. Just for simple battery calibration only...
I STILL RECOMMEND ONE POWER GUARD. IT CAN OPTIMIZE YOUR KERNEL, ROM, WI-FI, 3G AND I/O SCHEDULER SO THAT TO MAINTAIN BATTERY LIFE. IT'S A NICE TRY.
Here is the step (The developer recommend us to follow these steps but not necessary)
THE FIRST AND SECOND STEP IS THE BATTERY CALIBRATION PROCESS
1. CHARGE your phone to 100%
2. Click on battery calibration button first (battery calibration app or ONE POWER GUARD app), then only plug off your charger.
THE THIRD AND FORTH STEP ARE NOT NECESSARY TO PERFORM, I TRIED AND I SUGGEST YOU TO DO THESE AS THEY CAN ASSURE YOUR BATTERY ACHIEVES THE MAXIMUM PERFORMANCE.
3. Drain your battery until it shut off completely, until you cannot switch on your phone...
4. CHARGE your phone again until full, without switching on your phone...
(Some people recommend to charge 4/5 hours to 'heat' the battery chemicals, I just forward their messages, I am not understand why to do that)

You are welcome. I understand how it feels when your battery is draining like hell. I will also try new things. Who knows? Maybe will find out something interesting
I am now trying the new app called Android Tweaker. So far, after my device is fully charged, I 'Skype' with my friends about 1 and a half hour, using XDA app about 1 hour, 'whatsapping' and watching music videos. They drained about 21% of battery in 5 hours. Unfortunately I rebooted my device to flash something and my battery stats had reset, it became inaccurate.
Looks like I have to wait until next round fully charge then I can make sure is the Android Tweaker helps me to reduce more battery usage.
But so far, I deep sleep my device about
6 hour. And I made several calls about 30 mins of total time. And I did set an alarm, I was too tired and I didn't hear it. The music was replaying about 30min Haha so embarrassing Now I still have 53% battery and I completed my charge at 2am in the morning.
According to my rough calculation, I have used my note 2 more than 11 hours (Including all the activities I mentioned above, and deep sleep time) ADD: Wi-Fi on all the time, motion on, and auto brightness on.
Looks like quite OK for me. But I still want to take a few days to observe few times so that I can provide a more accurate result to you all.
THANKS FOR YOUR APPRECIATION AND I WILL DO MY BEST. I'LL KEEP YOU POSTED BRO.

Hi everyone,
My One X used to have brilliant battery life. I didn't turn on the screen that often throughout the day, but I was able to regularly check the news, send and receive texts, make a few calls and - crucially - keep my Wifi on for the entire day. With this setup, I was regularly getting 4 or 5 days of usage without having to charge my phone. However, as soon as JellyBean came along as an official update, I grabbed it... since then, I'm lucky if I get a day and a half out of it before I need to plug it into the wall.
I'm not running any custom ROMs: just whatever I get through official O2 OTA updates. Battery usage says that 36% of my drain is due to Android OS, with another 20% due to Maps. The rest are tiny, only 2 to 5%. Now I understand that a new version of Android might make some new demands on the hardware, but from what I heard, the update was supposed to improve battery life if anything. Even with the new Power Saver feature on, the difference is minimal, with only a few hours standby time gained overall.
Can anyone suggest anything to remedy this, or is this fairly normal? It's not world-ending and perhaps I was just really lucky to get 5 days of use in the first place, but thought I'd ask the experts before I grin and bear it. Thanks in advance for any help or advice.
19 hours and 40 minutes into this usage cycle, I've got 57% remaining. So it's shaping up to be about 40 hours of usage, down from 120 at its peak. Right now, it's also saying that Android OS has used 99% of my battery... and nothing else is on the list.
Does no-one have any idea what's going on?
Did you make an hard reset when you updated your phone?
This is why when you upgrade your phone to a newer Android version it is better if you perform a hard reset
AW: [Q] Battery life poor since JB
I suffer(ed) also under heavy drain due to maps since update to JB. But I'm convinced it's cause of Google Now. Disabled it yesterday and will check whether it gets better or not. Try disabling gnow and see if it gets better. I also had issues with gsam battery monitor in case you use this.

Would you consider rooting because custom roms like blade have great battery life

Thanks for this. Your suggestion got me checking for other people having issues with Google Now and battery life. I disabled it as you suggested and I'm definitely seeing an improvement. It's still not as good as it was, but I think I might be able to squeeze more than two days out of it now.
Do you have stock rom? Because I've just upgraded to JB yesterday and flashed a custom rom, and since then my battery is like 3 times more powerful.
You should definitely switch to a custom rom... Ever since I upgraded to JB I've seen a massive improvement in my battery life.. From barely making it through the day to almost 2days of my typical of usage.
Google Now does seem to kill battery as it polls the Google maps app a lot.. So I usually open task manager to make sure it isn't running in the morning background.

Bone stock, not rooted or rommed.
My battery life used to be phenomenal. I would check at the end of basically every day and averaged 4-8 hours of actual Screen On time. The Screen would account for 40-55% of the usage, followed by all of the*apps*that I had used that day. Android System and Android OS would be pretty far down on the list.*
Now that I have 4.1.2, I'm lucky to hit 3 hours of Screen On time. And now Screen, Android System, and Android OS are accounting for 20% EACH.
I haven't changed any settings or the way that I used the phone. The only thing that has changed is the update.*Is anybody else experiencing this?
I've gotten bettery battery life since 4.1.2, significantly better. Try to perform a factory reset or it could be a faulty device.

Yep and I have more or less tried everything including tweaks galore, every suggestion I coukd find, and freezing several dozen apps.
Nothing can be done about this and my guess is Samsung have made an absolute mess of the update. My HTC loses maybe 1% overnight on a bad day, this loses way over 10%.
I'll prob end up switching back to 4.1.1 but unfortunately it doesnt have the tap to reflow feature in the browser (which I use a lot)... I wonder if I can remove it via titanium and restore the newer version which would have reflow on 4.1.1 ??
I have the same problem. As soon as I took my phone off the charger this morning it dropped to 99%. On 4.1.1 it used to last for a good 20 minutes before dropping to 99%. Also last night after about 6 hours of screen time Android System was at the top of my list. And that is with 20 or so system apps frozen or deleted from running.
What's the easiest way to go back to 4.1.1?

Odin pc or mobile pc.. but if your rooted.. it is safer to use mobile odin it is faster and will avoid power outrange

Is there any way to get the browser from 4.1.2 onto 4.1.1? Titanium backup doesn't seem to restore system apps.
Zero battery life related issues here with 4.1.2 Im starting to think some people probably messed up their phones too much or just got a flaky unit/battery and 4.1.2 exposed those?

Well I dunno.. I have tried everything and there is definitely a battery drain issue. If it is caused by ebay/whatsapp + facebook, then I'm curious as to why they don't show up in battery usage or betterbatterystats... and I'm also curious why the exact same setup on my HTC EVO 3D does cause these horrendous idle battery drains.

Yeah already done all that and there doesnt actually seem to be anything using over like 5%.. I have elimated the higher one yet it still drains ovwr 10% at nite. Or in general idleness.
What I became accustomed to with my previous phones was 0% or 1% drain over many hours if the screen was off. Not 2% or more an hour.
1% drain over 9 hours of deep sleep on Wanam2.8

I had the same dreaded android os battery drain issue after updating to ma8. Used to have great battery life before that. After freezing Google search, Google now, still no use. Then i realized I installed another weather app at the same time I upgraded the os. Bingo. Un installed that offending app and that fixed the Android os battery drain issue. Hope this helps.

That's specifically my DBT rom (stock everything as well) and I've had battery issues and to be honest, it's still better than most other phones, but I'm getting about 40% less life out of my device now.
I have flashed again, I've reset, and deleted everything and still no luck. It's something with the ROM. I hope the next update will fix it. If it doesn't, I'll revert back to 4.1.1 because I would go to bed with 50% battery life, now I have to charge in the middle of the day if I want to get through a long work day with lots of use.
well the new french 4.1.2 N7100XXDMA6_N7100OXADMA5_N7100XXDLK7 is much better than the last one rlsd in december and my battery drains less now

I'm on 4.1.1, to be exact wanam 1.5 and when I test using emmc check my chip is sane and I passed the test. Should I be worrying about sds?

i also have same problem on XXDMB2 .i think only some people have battery problems with 4.1.2. Is it related to emmc firmware 0*1f ? Is the kernel reparing the bad sectors by itself? and what is kworker process?
I installed 4.3 update and noticed that the phone gets pretty warm with normal usage. When i'm not using it, the battery temp is about 30c, while doing not to tasking tasks, like browsing it's about 32-36c. EDIT: It got to 40c when I was browsing today. Is this normal?
I hope you aren't using Google Chrome...

Google Chrome is too much demanding for the CPU, given its crapness.
However, my C1905 rarely get over 35°C of battery temp, maybe you have some intensive background app staying on all the time?
Post some battery usage and running services screenshots.

Ok, so i did a factory reset today, battery seems to warm up less, still, when using it for a while, it is usually 35-36c(atleast that's what cpu-z says. The other thing i noticed today though, is that i actually have 1700mAh battery. I bought it from my carrier, so it's a new phone. Did anyone else got weaker battery with this phone?
