As title says guys, I don't no why but my battery life is just really bad since I moved from stock 2.1 Rom to custom ROMs :-(
Is it my phone? I can't work pig wot it is. I checked the battery usage #*#*4636*#*#) and it seems the Android system is using A LOT of it. I tried charging with phone off, clearing battery stats, not overcharging, but just can't resolve this issue.
Also, I have sync set to update manually and have mobile internet off always, only on wen needed. Same with WiFi. Screen is on auto and time off screen lock set to 30 seconds
I am using OpenDesire sense Rom
Any help will be really appreciated.
Thanks

I could feel WiFi siginal of 2.2 is much better that stock 2.1,
I suppose that the better performance will bring the fast battery drain,
if your custom ROM support WiFi N mode,
that really makes your battery life short that before.
I have the same problem and same settings as you. I read on other forum that people who updated to official 2.2 have even better battery life.
I cant even squeze 20 hours out of my battery :/
You guys should always post what ROMs you are using...
Opendesire 3.3, its the same with defrost.
i also had really bad battery life on those 2 roms
even doing nothing the phone would just keep dropping
go to official froyo 2.2
neophye roms for me have amazing battery life = 48 hrs..

Is there another non sense rom? I really like stock better...
Check if the phone goes to sleep correctly. Spareparts > battery usage: other usage, since last unplugged.
I had the same problem, until I found out that the phone was not going to sleep. (running and screen on percentages were way off. Almost 100% running and a lot less for screen on.
update to the last radio
I found that after forcing everything to install to SD card my battery life plummeted. There were apps/widgets that should have stayed on the phone. Once I moved these back, battery life was back to normal.
I use Systempanel to see the battery drain graph and could see a pattern to it.
Same issue here, Will try Neophyte tonight
Using this rom http://forum.xda-developers.com/showthread.php?t=741663, and it's fantastic! However batt life on .08 and .20 radio is a shocker. I watched a 1 min trailer on youtube, in and out and I lost 4% battery. Before with OpenDesire I'd be shocked if the battery percentage even twitched slightly.

I use Defrost 1.5a and I just use about 2% every hour when the phone is sleeping, and that's with auto sync and mobile data enabled. (disabled it's 1%/hour)
Always underclock to the lowest mhz when the screen is off using SetCPU and when you do use your phone make sure the brightness isn't too high.
I could make a whole list of tips, but I'm sure you'll find more than enough of those on the net.

I may be dumb but how do you force your phone to go into sleep once screen is turned off ?

(using Cyanogenmod 6)
When your screen is off, your phone should automatically go to sleep. Sometimes widgets or apps keep this from happening (like the music player), making it use battery as if you are constantly working on it.
How I resolved this issue was to find out what app or widget caused this. I ended up starting from a fresh reset, installing first all apps I really use (calendar/message widgets, powerstrip etc.)
I tested by installing an app, rebooting (or sometimes not), check the running time of the phone, turning screen off, and check again in 5 minutes. The phone should go to sleep in about 30 - 40 seconds. I am telling you this, because most apps causing this are widgets/apps running constantly.
However, I found in spareparts also that 'settings' was taking alot of usage time in usage statistics. A simple reboot did the trick from here on. But I am guessing I had installed something which made some app not close properly..
Maybe it is better to have a task manager/killer for these situations.
Running and Screen On percentages should not have too much of a difference if your testing and not using the phone while screen is off (music, bg stuff)
You could try juicedefender, it helps improve battery life by disabling unneeded connections while the phone is not in use
Hi Guys!
I am facing a very extreme battery draining situation...
Something is keep waking up my phone while my screen is turned off.
Is there any good app out there I could monitor / Find out what is constantly waking up my phone? I can not find any good app for that.
Thanks for your help in advance.

Settings->About Phone->Battery->Battery Use
Get yourself rooted and grab SetCPU. I have a profile set on that which underclocks my CPU when the screen is off. Doing this GREATLY increased my battery life.
I also use Tom Hubalek's Battery Gauge Widget to help me monitor my battery. But, after using the RCMix S v2.0 ROM and calibrating my battery (and the mentioned CetCPU settings) I get a good day out of my phone with a lot of wifi and 3g usage.
Never had any issue so far with my battery... I am checking battery usage in the settings menu but it is not enough. Need to see what exactly using my battery 'cause its unacceptable to drain 60% in 5 hours... The only thing I can see that something is using (waking up) the phone even when the screen is turned off...
I am using SetCPU as well with Smartass governor... can not be the problem...
Also set a profile for screen off - i have it set to 245min-245max smartass. It seems to save battery more than just set on the main screen.

Have you tried changing the Wi-Fi sleep policy? Also, pocket mode and fastboot, if you have those options.
My SetCPU is set to OnDemand. I thought Smartass was unstable and gobbled more power than it should? I dunno, though, I use whatever the ROM developer uses for the ROM; I don't change anything.
But you're right, my phone has lost 61% in 14 hours. 60 in 5 is wrong.
I think JuiceDefender has some of the features you're looking for, though:

Ach, I have mine to 245-600MHz when the screen is off. Any less and my rom is lacky when the screen wakes. Had the same settings as you for other none Sense 3.0 ROM's though. MAJOR power saving. If you leave your phone downloading, though, the screen off profile kills the download rate.
Check it out, upload a file to your phone via wifi, turn the screen off and watch the speed plummet to about 100kbs!

Anyway, I had a massive power saving when I used this ROM:

Dialer
If you're using a gingerbread based ROM, it could also be the dialer. At least it is for me. Sometimes he just goes crazy and I have to reboot the phone. Apparently the dialer checks the phones proximity using the sensors again and again.
For further reference and solutions see: http://forum.xda-developers.com/showthread.php?t=1069251
Juice defender and Setcpu are in the same basket as task killers.
If you are using Smartass you don't need any profiles. Check your widgets, probably you have one which updates every second and kills your battery.
Hey guys, I was getting terrible battery life when the phone is idle. I looked into it to see what was going on. First off, I am on the stock rooted deodex'd ROM that scrosler posted. The biggest problem was an app I installed called Light Flow Lite, it controls your LED. It had over 6 hours of wakelock today. Removed it, not worth it at all.
The second thing I found that was interesting was after that, the phone STILL wasn't hitting deep sleep. I poked around in BetterBatteryStats and didn't find anything in there that would explain that. I then ran a "top" (in terminal or adb shell, type top -m 5 -t). Everything looked normal, nothing crazy. But I turned the screen off and let it run for a few seconds. I got a massive spike in CPU (anywhere from 15-35%) for system_server with the thread "WindowManagerPo" (which is likely short for WindowManagerPolicy).
I did some searching and it turns out that there is a bug with auto rotation that causes this. Essentially, the sensors don't stop looking for orientation change when the screen is off. I found reports of this in the Nexus S forums, GS3 forums, etc. This leads me to believe it is a Samsung kernel issue, since that's the least common denominator when it comes to the phones that had this issue. If you don't use auto rotation, you probably aren't encountering this issue (but keep reading for some good info below!) But I use auto rotation, how can I fix this?
Download an app called Auto Rotate Auto Lock. This app will turn off auto rotation when your screen turns off and enable it back when you turn the screen back on. This looks like this should really help to combat this bug and it handy for people like me who like auto rotation but don't want to have battery life suffer from something as stupid as this. I have verified that my phone now does enter Deep Sleep easily, and it hadn't hit that all day!
I also recommend an app called CPU Spy Plus (XDA thread). This app shows some very valuable information about your processor. You never want to see "Deep Sleep" under Unused CPU States as this means your phone isn't sleeping and is wasting battery!
It would also be good to download BetterBatteryStats (XDA Thread). This will help you nail down battery drain that you won't see in the stock Battery graph found in Settings. Things or importance are Partial Wakelocks and Alarms.
Monitoring these apps can really help you to increase your battery life on your phone. If anyone else is having bad battery life when idle, please try this out. I'm sure this will help you Feel free to ask questions, I will try to answer them as best as I can!
I have autorotation turned on but not the face orientation sensing. I haven't noticed a significant battery loss, at 19 hours with 10 left according to battery spy, but I'll give this a try and see if it increases it any.
i'll give it a shot. i was wondering how at work it would drain 2-4% an hour but at home with a crappy signal i'd only lose 6% all night.
at work it's in my pocket and at home it's stationary.

I have noticed Google Talk drains batteries when your signed in. By default your phone will sign in. If you don't use TALK, sign-out of the app and you will see increased battery life. Your wont ping the internet as much which saves batteries.
Thanks viperboy I took your suggestion and so far it seems to be helping.
I haven't tried that app yet, however I have definitely noticed an improvement in battery life by disabling auto rotation. Thanks for the info.
THIS NOTE 2 IS SENT FROM A GALAXY WHERE SAMSUNG SPRINTS TO THE TOP, AND JELLY BEANS EAT APPLES!!!!
after a bit of troubleshooting i found that battery monitor widget pro was the cause of my drain. after removing it i went from 2 to 3% an hour to 3% overnight. this really sucks as i love the info bmw colleects. this is the only device i have that suffers drain from the app.
Thanks for the info. I have been losing % 15 battery every night while I'm asleep and was wondering why

Thanks for the suggestions. I have heard so much about the great battery life, but that has not been my experience. I had a Note 1 and I had no problems. With Note 2, the battery drains to about 1/4 after about 7 hours with limited use. I have turned off auto rotation, lowered the screen brightness, changed auto check settings for email, and don't see much difference. In addition, it seems a shame that I should have to figure out ways to use fewer functions to make battery last for phone calls, since I never had to do that before. Any ideas?
Thank you for this info. I consistently get a full days charge of of my phone but was pretty clueless when it came to what was draining my battery. I've used the rotation lock app and will report my results to see if I get even more remaining battery each day.

As viperboy mentioned, BetterBatteryStats is your friend. It really will help you figure out why your phone isn't sleeping like it should. It definitely takes some time to monitor and figure out what the readings mean to help point you to the apps or settings that're affecting your battery, but well worth it. I also like having a better understanding of how things work on my phone.
i did a double check on battery monitor widget pro and it started draining my phone again. as soon as i uninstalled it everything was fine again. this is with both cleanrom and blazer. i'll just wait til official support comes and try it again.

Have you tried the Perseus kernel? I hear the battery life is improved with it. So may be it doesn't have the rotate issue.
I've been using cpu sleeper and I easily get about 30 hours. Looks like the new apk fixed quad core. So when the phone is off it only uses one core and shuts down the other three and lights them back up when you need them.

That app is unnecessary. Pegasusq governor already does that by default. Goes to 1 core and 200mhz when screen off, at least that's how my Note 10.1 was. I assume it is the same here since the International GS3, GN 10.1, and GNII basically share the same kernel with a few minor differences.
I think I may try the perseus kernel today to see if it improves battery.. I haven't heard it does.. I just been seeing people do that benchmark stuff with it
-TeaM VeNuM Like A Boss
Interesting... I have a script that reports on CPU freq and, when plugged into USB (maybe the wall charger too, didn't check), it appears that the kernel runs cpu0 and cpu3 all the time, even when screen off. With the phone unplugged, it went to using only cpu0 but didn't cap the freq. It was spending a good amount of time at the higher frequencies even though I had nothing running.

I installed the app to turn the rotation off when the screen is off so far everything good but when I get a call this goes crazy because the screen goes while in call. I know this because I have an smartwatch which it has a notification app and every message that the phone has my watch vibrates with that message and I had a call few minutes ago my watch started vibrating non stop until I hang up.

For some reason my M9 doesn't want to go into deep sleep much. Out of the 1 hour I have it off the charger, only 2 minutes were in deep sleep. I haven't used the phone at all in that 1 hour, so I'm not sure why it wouldn't be sleeping.
Does anyone have this problem or know how to fix it? Thanks

I've used a very similar app. There are no wake locks. All it says is "Android OS" is using 100% of the screen off battery. Even in the normal HTC battery settings, android OS is using 100%. Thanks for the help though.
System Panel is neither similar nor showing you those funny wakelocks..
It thoroughly informs you about CPU usage last night..

Thanks, but all those apps are the same. They can only get a certain amount of info from the core system. There are apps that do the exact same thing for free, which is what I use.
As an update to my problem, rebooting the phone and clearing cache seemed to have solved the issue for now.

If you run out of ideas on how to fix this, I'd say get root, get Xposed, and get Power Nap. Pretty much blocks all wakelocks at night and I see like 1% drain the next morning.

Wait...xposed works on 64bit phones? Wow I've been missing out for nothing lol.
Yes, but make sure you use the xposed arm64 file.
This thread has the stuff
Here's the zip you want xposed-sdk21-arm64.zip
And you also need the alpha installer.
Been poking around here and reading all the posts that people had mentioning battery life on stock/cm11. Is battery life really that good? I find myself trying everything possible (including hardly using the device, turning brightness all the way down, turning off bluetooth & Dynamic perspective) and I find that my phone is dropping like a brick. I can have the phone lose %s in front of me just having the screen open for a few minutes doing nothing else.
I even have two apps to optimize/kill all other apps and I'm finding that this phone is dying faster than a t-mobile pre paid LG L90 I was using prior. I just don't see how people with stock and all the features on are getting more than 5 hours battery life tops. This phone dies while you use it on the charger, which is a first from any phone I've ever used.
How do your experiences stack up? Do I just have a bad unit? Really considering going to cm11 now (really wanted to like Fire OS).
You must have something wrong with the phone. I have had Samsung S3's and S4's and the Fire is far and away the best I have experienced for battery life. I am getting close on two days on a full charge although I do not use it a great deal for voice calls.

Are you keeping Dynamic perspective off with a low brightness instead of auto? Don't see how two days is possible unless you absolutely never used the device. I can lose like 10% an hour just on the browser reading text sites.
Fire has the best battery life of any android phone I've owned. I'm on fire os with a different launcher and I have dynamic perspective on (not for home screen obviously). I'm also using auto brightness. I'm rooted with gapps installed. I get great standby time and even in use its good. You should get gsam battery monitor and see what's going on, although I think you might have a broke unit.
Here is a picture from Gsam (I don't have my phone rooted). I think this is pretty bad for only 3:28hrs of screen on time and that was with the screen at the lowest brightness, not on auto. For app usage I have 7% coming from a game I was playing, but the rest of the drain is coming from system and kernel. Would really like to see another users stats with similar screen on time, as I'm pretty sure I could completely kill this phone's battery in 4-5 hours just using silk browser on Reddit.

Can you check the kernel wake lock section of the same app?

On the off chance that you or anyone else can help me understand what's going on I ran a ~10% drain test and made a picture including information from WakeLock Detector and GSam. This drain seems very bad considering the screen was only on for a total of 16 minutes and I lost 8% power.

Your phone isn't going into deep sleep. It's hard to determine exactly what's going on there but if you download kernel adiutor (yes, that's the spelling) you'll see its locked at 300mhz most of the time. I know it sounds crazy but have you rebooted? That can often sort out a misbehaving app. Are you rooted? If so deploy greenify.

Do you have any recommended settings for that app? I disabled something that I think is allowing me to enter deep sleep more, but I have to finish testing. Thanks for the help ratbags!
Oh I see what's the wrong.
Battery usage give me a wrong information.
My fire phone lasting about 5hrs turning on screen.
Very very good !!
Thank you.:good::good:
Five hours is good??

5 hours of "screen on time" is solid, the combined time incl. standby, etc. is of course much longer. He didn't know how to interpret the statistics from the device, it was a misunderstanding.

That kernel app won't help battery life but it will show you how long you spend in deep sleep.
As for greenify, you should greenify all the Google apps. I actually greenify everything except sms app, browser, phone and alarm apps.
Also, this could possibly be some kind of location based frippery. Turn location services off or onto battery saving mode if only temporarily. And turn off auto sync if it's on.
