In many cases, people who have battery drain issues have a tendency to end up being found to be using a known battery draining app or configuration. To help these people, I'm going to try to start a list here. I will, in the case of known rogue apps, include the reporting date so people can try updates to see if drain is fixed. (For example, Facebook is rarely a culprit any more, but it was the #1 most common battery eater in 2010.) The primary focus here will be things that shouldn't drain your battery but do.
Firmware bugs:
The UCKK6 OTA update contains a number of issues with wifi and bluetooth. Among these is that an oddball feature of our Wifi/Bluetooth chipset goes nuts and wakes up the phone once per second intermittently. Rebooting temporarily fixes it, turning off wifi temporarily fixes it, only permanent fix is to ditch UCKK6. http://forum.xda-developers.com/showthread.php?t=1409513 for more details - Appears as a variant of the Android OS "bug" - this is the only one that is actually 100% a firmware bug. International XWKK5 is also affected.
LAN Environment (WiFi):
Broadcast LAN traffic can wake your wifi chip often. This also manifests as the Android OS "bug", but it's a small problem with the firmware base (XXKI3 and UCKK6 are known to be affected) and mostly a network problem. Examples I've seen so far include:
Windows Client Backup
UPnP (DLNA) SSDP
Dropbox Lan Sync Discovery Protocol
Buggy piece-of-**** routers that spam lots of ARP requests continuously - The 2Wire routers that are required for UVerse access apparently fit in this category.
You are more likely to have the above issue on some firmware bases than others. For example, XXKI3 disables all of the chip's packet filters, making it vulnerable to this sort of thing. UCKH7 and XWKL1 don't, leading to significantly improved life on "dirty" networks. UCKK6 almost surely also has the same problem.
Configuration issues:
Hotmail calendar sync
Misconfigured Microsoft Exchange servers - 1) is a special case of this. At least one person has reported that calendar sync to a non-Hotmail account was problematic for them, but email sync was OK
A bad Exchange configuration - the client apparently goes nuts if it can't contact the server
BLN - On Galaxy S II devices, there is no stable BLN implementation that does not hold a wakelock when a notification is active. This means that an active BLN notification will drain about 4-5%/hour. I say this in bold letters in my kernel thread, but somehow people still don't realize it...
Rogue apps:
Words with Friends (October 2011)
Skype (October 2011) - Particularly insidious, as it does not directly hold a wakelock. However, it causes lots of background network activity, and this activity keeps your phone awake. Since most of the time is spent wakelocked in the network stack, Skype drain shows as Android OS.
Any IM app that works similarly to Skype is likely to have the same issues.
AP Mobile Widget on stock AT&T ROMs - this one also blows through your data allotment quickly if you don't have unlimited data
AT&T Smart WiFi can sometimes hold excessive wakelocks - this is why AT&T bloat is bad for you.
The Obvious:
3D or animation/action-intensive games
The Rare:
Apps that occasionally go nuts, but not frequently
Facebook - I've had it wakelock me once, and also, Facebook chat may have triggered my first obvious "AOS bug" episode once - so far, it's been responsible for drain once this month
StartingAlertService - some sort of Calendar notification related bug
The False Blame:
GPS Status and Toolbox - may appear to be high-drain but is actually not draining - this is an Android battery reporting bug - see http://forum.xda-developers.com/showpost.php?p=23106668&postcount=491 for more details. Thank you for the info and the great app rhornig.
If you're having battery drain issues, I suggest the following:
Install BetterBatteryStats. The XDA edition from the author's thread on these forums is free. (Market version is paid.)
Also, having CPUSpy to see deep sleep percentages is VERY useful
BBS now shows kernel wakelocks - make sure to check these. If you have an older version that doesn't show kernel wakelocks, use the instructions below.
Get ADB up and running (Google it, and if you're on Windows, Googling Droid Explorer may help)
Using ADB, do the following:
Code:
adb shell cat /proc/wakelocks > wakelocks.txt
adb shell dmesg > dmesg.txt
Zip em' up and post em' here for analysis.
Edit: Specifically, to get a good baseline measurement of idle drain - make sure to have CPUSpy installed for this procedure:
Charge phone to full
Reboot
Reset timers in CPUSpy, otherwise the percentages and bars will be wacky
Let the phone sit for a while - Overnight is best. Then provide data:
Deep sleep percentage
Time the phone was sitting
Percentage battery drained
I don't need screenshots of the above, just the numbers. Screenshots use up massive amounts of thread space
Grab /proc/wakelocks as mentioned above and post it, OR use BetterBatteryStats 1.4 or above to pull kernel wakelocks.
Note: If you're at or below 1%/hour idle drain, not much point of posting your wakelocks.
If you have high wlan_wake, wlan_rx_wake, or svnet-dormancy wakelock times, then you have an app eating data or one of the wifi wakeup bugs described above. Install Shark for Root - https://market.android.com/details?id=lv.n3o.shark
Start it, and change parameters from:
Code:
-vv -s 0
to
Code:
-vv -s 68
This tells it to only capture the first 68 bytes of each packet, which is all we need for this purpose. This provides two benefits: A smaller capture, and privacy for you. (It captures packet headers but not contents)
Then start a capture and let it sit for a bit.
Note that your drain will be higher during the capture than normal - we're collecting data here, not directly nuking the drain.
After a while where you are positive you are encountering drain, stop Shark and then pull the .pcap file - load it in Wireshark on your PC or post it here. If you post it here, MAKE SURE you have a truncated capture as instructed above!
Thank you sir. Will do in a few.

Words with friends is an insane battery drainer. I had a screen on time of 4 hours and 15 minutes with 35% battery use and Words with friends had a 45 min cpu usage and was 26% of the battery drain...There is no way that should be so close to the screen usage. CRAZY.

I spent a while testing that app before finding out it is a phone-wide issue. Emailed the dev today but we'll see how it goes. Not a small dev anymore.
Yea I hope they fix it...I love playing it but it kills my battery. If that app didnt run I may have like 5 hours of screen time on a single charge if not more. I looked at many of the reviews of it and many of them mention the battery killing it does.
Just discovered an interesting feature built in to the stock rom. Go to task manager > storage and you'll see it©.
The tower defense game Sentinel 3 will put a HEAVY drain on your battery.

Huh? What happens?
Apparently an app I come to love and use on all my devices is Battery Monitor Widget. According to to someone's post from the BBS thread and due to my own investigation. BMW will cause a lot of wake time up to 970 awakes over a 12 HR period. That is a lot time consuming battery and resources.
rebooted my phone reset cpu spy and going to leave it not charging and I will abd into the phone and get the demesg and other file and post here.. been losing 30% over night on about 8 hours which I know is way off... no skype I have wifi data sync and gps on as well as syncing a google account twitter tango and facebook.... which I understand might be alot but shouldn't this phone be able to handle all that? I also live in a basement with poor service but right next to the router... getting a microcell on Friday which I hope helps. My AOS is around 65% in battery status and suspend and events/0 are definitely running more than one minute every 10 hours, more like 20 minutes at least every charge, and my phone is lasting 11 hours give or take with minimal to no use

Suspend and events/0 at 1 minute every 10h aren't too bad. AOS at 65 is a bit high.
Unless one of the above apps you use is implemented badly, your phone should be able to handle the above. I have Google and Facebook and get great drain. I haven't heard reports of Twitter causing problems.
Tango is an unknown - it's in a similar class to Skype so could be driving excessive idle network traffic.
To the person who posted that a game drained their battery - well, that should be pretty obvious. I guess I'll add it to the first post later, but I'm primarily focusing on the "non-obvious" stuff - things that SHOULDN'T drain your battery but do.
Tango is all good had it installed on my phone forever my batt life is amazing. It doesnt require a sign in. Look out for anything that make you sign in besides google as far as im concerned

what I meant to say about the suspend and events/0 is that i wish i was getting a minute every 10h, it is more like 20minutes.. I just finished my over night test, I put the phone down at 11:09 with 69% battery left, waking up just now with 30% at 8:16, did not touch the phone once.. should have been asleep the whole time.. also my suspend is at 31minutes (BBS) and my events/0 is at 30minute (BBS), i also reset my cpu spy. deep sleep 5:49 hours, 200mhz 1:29 hours and 800mhz 1:21 hours (14%)
and lastly, here is my dmesg and wakelocks... so yea this looks pretty horrible to me!
I actually went to the at&t store to exchange this phone yesterday cause I am convinced something is wrong with it, no one really seems to be getting the severe drainahe and stats that i am getting, so I assumed it has to be the phone, well its 2 weeks old and the guy wouldnt take it cause he needed proof there is a battery problem.. Also I went back to stock yesterday before i was going to exchange my phone and the issue seemed to be happening aswell no matter where I was and what apps were installed, hoping these files will figure something out! thanks for your help!
There's alot of careless and sloppy developers out there that has no concern on users battery. Android support Push notification since froyo and it's only implemented in a few apps like tango. Why? Go to the appstore the same exact IM and video chat apps uses push notification, but not on the android version. Instead you have to log in all day clogging your Ram and battery. As of now the only IM client I use it's Google Talk screw Skype oovoo ect or any other apps that has no push. BTW Facebook it's another mess, soon Ill be deleting and using the browser.

It seems to be the same issue as everybody else is having, getting excessive network traffic waking up the phone. Either you do a network capture of the packets and identify it by the highest common port which comes in (complicated), or you turn off each service off one by one. In the last case I'd start with the network location service (Kill it with Titanium) as that was known to be a *****.

so you think I should freeze each app one by one and let chill for an hour and see if there is drainage or not? is ot just processes or apps? cause I would never know to do something about network service unless u said something.. BTW I did, and i still lost 4% battery in an hour of idle.. so thats not it.. what about using this the other way you were talking about

ok, so I did try this to an extent, i would disable 4 apps at a time for the most part, only apps, none of the red items like wifi manager and stuff like that (even though i did try that at a different date)
I had no success.. I went back to stock, uninstalled all bloatware, at&t live TV, my account, bar scanner, all that bs, right now I have BBS, Cpu Spy and titanium, only apps that are not stock and are in the list of installed apps. I am still getting this issue!! could it be that I have poor service (though this never affected the iphone this badly) I lose 40% overnight though and it seems odd to me that would be because of low service..
GO.Keyboard and GO Contacts ( especially GO Contacts) was draining my battery at a phenominal pace. GO Contacts was using more battery than the display

I am completely new at this, I read that some say the battery drains too quickly over night while in sleep mode (running the vegan 5.1 rom), even when wifi, sync, etc. were shut off. Has anyone else experienced this? How is this compared with iPad? Thanks!
I'm too a bit concern about this issue. Does this problem occur on Vegan ROM only or other ROMs?
What about standard ROM?
Why not just plug it in overnight? Seems easy enough...
Well, it's all about convenience. I just don't want to remember to keep thingy plugged in overnight, every night...
With average usage about couple hours per day - single charge should lasts for 5 days.

I had to retrain myself when I got my HTC Incredible. I keep a charger at work, home and in both vehicles so I always have power available when I need it. Once I rooted, installed Hydra Kernel and got rid of the bloatware my battery uptime was significantly improved.
I suppose the bloatware on the stock ROM would cause some battery drain that would be helped by a custom ROM or at least removing the bloatware that you do not need.
Yup, that's the question. Which ROM has least amount of bloatware...

VEGAn is pretty clean if you ask me, but I did stream line it a bit for battery life.
System app remover is awesome. No more using terminal to pull apks manually.
I Yank out the tts (text to speech) stuff
I pull streetview and gmaps (I can get directions from gmaps online if I need them)
I pull email and Gmail (the galaxy tab email port runs my Hotmail and Gmail from one app and I can tell it to never check unless I press the check button)
I pull the news and weather app (I can control update regularity with beautiful Widgets to sync once an hour as apposed to once a min with stock)
I gut out the stock browser and launcher after replacing them with dolphin HD and launcher pro.
There are more but since I already pulled them I can't exactly check
I get amazing battery life this way. If I shut it down when I'm done with it I can make it last all week on one charge at about 3-4 hours of moderate use a day.
I can use it all day heavily and put it to sleep at night and still wake up with 30+% battery.
Looks like gTab never goes truly asleep, just turned screen off. Some apps continue to work.
Thank you, I will give the systemapp remover a try.
This is where the Ipad and the Gpad are totally different. I can charge the ipad to 100% and wifi wll be turned on and I can turn it on a week later and the battery will be at 99%. The gpad with wifi turned off will be down to nothing in just a couple of days. Like someone said the thing is never off. I hate having to keep it plugged in all the time.

Under settings / about look at battery usage and you should be able to see what is using your battery.
I used system app remover to take out all my reduntant apps (launcher, browser, music player, ect) and set my wifi to turn off when the screen turns off and now my gtab just sips the battery.
I went to bed with it at 41% last night and checked it this morning as I was about to leave for work (8 hours later) and the battery was at 35%! Before I was losing almost 20% a night so this is a HUGE difference!
I'm going to try to optimize a little more when I get home. The only app running that I dont really need is the Amazon Market so I may get rid of that and see if that helps any. My goal is to get it to .5% battery drain per hour.

Setting the wifi to turn off with the screen is a HUGE power saver. When my gtab was draining a lot of battery I looked up the battery usage statistics and the wifi was using almost as much as the system idle!
I think right now I'm hovering at about .8% battery drain. I might turn off my RSS widget since I mainly use Pulse as my news source now. .5% here I come!
Well, I set WiFi policy to Off when screen is off and use Task Killer to shutdown every running process before putting tablet asleep and still battery loosing charge from 91% down to 77% in about 10 hours.
So, my numbers are about 1.4% per hour when gtab in "sleep" mode.
I check WiFi router and can see that gTab does switch WiFi off...
Question about that system app remover. How it removes redundant apps (say like stock email, music player, google search) from read-only system partition?
I thought that the only way to remove them is to rebuild and then re-flash ROM without those apps.
That's why apps like "Advanced Task Killer" etc. only kill processes from memory, but then Android re-launch them again.
I understand, that for phone not to fall deep into sleep is a feature, but for a tablet it's just a waste...

I installed "SystemApp Remover". It lists the apps in 2 categories "Regular Apps" and "System Apps". Regular apps are the ones you can remove normally without this app; the ones under "System Apps" are the build-in ones that you can not remove using the usual method. Once you select "System Apps", choose "Assist" in settings, and the app will highlight the system apps in 3 colors - green, yellow, red. Green=ok to remove; yellow=maybe ok to remove; red=removal not recommended.
I suggest you know what you're removing even for the green ones. The name of the app usually tells or just Google it. You can also back it up in settings before the removal.
I have removed some, not enough to test for results yet, but I've seen a few positive feedback from others. Just be careful while doing it, that's all.
Interesting, what is the most "power hungry" or better say - "refusing go to sleep" application?
I understand, this tests might be tedious to do. I think that the best candidates are those who are restarted on its own after Task Killer killed them..

Try "SystemPanel", it has a function that monitors which app uses the battery the most. According to its description, the monitor function uses about 1 minute of battery if it runs for a full day. And, the monitor function can be turned off and nothing else would run in the background from SystemPanel. There is a Free version as well.
Having been facing horrible battery drainage for a week - the phone left unplugged to overnight was loosing about 70% of battery charge...
In the morning in menu>>settings>>about phone>>battery>>battery use>>battery chart
AWAKE was showing continues blue line throughout the past night... and the fact that I had recently installed the other fifteen apps made the situation even more complicated :-(
Long story short, as result of analyzing battery use chart, System Panel app history tab, as well as uninstalling/installing my programs one by one, the application what was preventing my Amaze from going into SLEEP mode and draining its battery appx 8% per hour - was identified.
It turned out to be the Amazon AppStore - by the way downloaded from the official web site.
So, do not allow this fabulous app to remain in background (unless you do keep your dear amaze consistently plugged in), and after the use always kill it. Now I am treating it as follow menu>>settings>>apps>>manage apps>>Appstore>>"Force stop" followed by "Clear data" ;-)
However! Even after such my treatment it keeps 'working', the relevant chart in System Panel reads that - six/eight times a day the CPU is being loaded by this particular application!
O.K.
There has been one more app found among my operational environment able to prevent entering the SLEEP mode. It is IM+ Pro. This messager can run in two ways - Background mode and Push mode. When left in the Background mode it won't let our device to enter SLEEP, cousing the similar battery drainage as Amazon AppStore does.
O.K.
Merci beaucoup! for reading my post . & I am happy to add, that now my phone battery consumption in the STAND BY is for sure below 1% per hour .. left unplugged till morning the device is loosing no more that 4%, in fact the signal reception quality line is never marked with green color on the overnight chart in 'Battery Use'.
P.S. Worthy to be also mentioned, during my checks and playing around with System Panel, there have been spotted the apps, what if left running in background (with eather status - 'active', 'cashed' or 'service-only') on one side allow the device going into the SLEEP but on the other keep repeatedly loading CPU around 0.5 - 2.0 % each, what in my opinion is already battery consuming.. The spotted apps are: eBay Official App, Text Free, Control Panel, Maps, Startup Manager & HeyWire.
P.P.S. Probably no need in synchronizing emails frequently during night time - such task is pretty much battery consuming too.
I'm using quicksense 2.1.2. Left it on last night at 79% then in the morning, 74%

Thanks for reporting this, i would have never guessed it because the only task manager i have is the factory htc one. I was wondering why my battery would drain so much, i would unplug it at 100% and a few minutes later it would crawl down to 94%(with the anker battery). I uninstalled it and now lets see how different my battery is.

But I see the file extensions need to be added - as JPG..
Good post for giving people some great starting points to help solve some of these problems.
One thing to note: I have the Amazon App Store as well, but no battery problems. My device is rooted and, it's likely, that it's not entirely the app's fault that it's draining the battery, but rather something between the app and Sense not playing nicely.
I've had several apps that would either labor the processor or crash when sense was running that run fine now that rooted.
Hi, I have a few questions regarding various wakelocks that I hope somebody will be able to advise on. Whether they are normal or not Im not sure.
I'm in the UK, my phone is a standard GS3, ie not routed or anything. I had battery life problems but have used Better Battery Stats and GSAM Battery Monitor and found the problem so now all is well and the battery is lasting exceptionally well indeed.
Whilst spending hours finding the original battery drain problem and removing the rogue apps, I came across these and just wondered; are they normal, is there anything I can do to improve them?
1) Android system - Seems to be causing quite a lot of wake locks, particularly running a lot are the Accelerometer, gyroscope & light. What exactly are they, and is it normal for them to be running a lot and cause wakelocks?
2) Facebook - I have turned sync frequency and notifications to 'Never' within the app, and set to not sync contacts, yet its still always in my list of running applications and causing wakelocks. Why? Is that normal, and what can I do to stop it? I only want it to turn on and refresh when I use it (very rarely) - which is what I have set it to. But it keeps running and starting itself even after I force stop it.
Thanks, John
Anybody able to advise? Particularly point 1) above.

1) Can you post here the "Dump" file from BetterBatteryStats ? You can generate it with BBS > Options > Dump to file
2) Facebook is known to drain battery with background daemon and services. Try using another Facebook'apps even if it's not the genuine one.
Isnt' cross-posting generally not allowed?
Thanks lelinuxien52, yes I will do that.
Szadzik, what do you mean by cross-posting?

Rooting and apps like Greenify.

The phone probably never sleeps the way you have it set up. All that stuff syncs in the background and therefore never lets the phone sleep. Stuff you don't have to know about constantly you should either turn off sync and manually sync it or try making it sync like say every hours or 4 hours not every 15 min. Honestly there are maybe 30-50 things that can cause your battery drain from a stock device that is new. But that is where i would start.
Also, make sure your GPS is off and your not using location services from VZW but just the normal google.

great info....so what about some of the apps that people have said to install? i dont really want to root..especially since there is NO recovery...
also..i checked and i did notice it was awake allot, and GOOGLE CONTACTS took ALLOT of kernal usage..
Honestly I dont like apps used to control other apps. That means they run in thr background causing cpu cycles... hence waking the phone.
if youre not going to root, then go into the app manager and disable what you dont use and what youre able to. Not all apps are disablable. I even disable maps untill I need it
I noticed a lot of battery drain with my rooted ME7 version. Greenify helped but what really worked for me is this: Go to System Settings>More>Location Services and disable Wi-Fi & mobile network location (Google Location Services). Use VZW and Standalone GPS only. It may take your apps a tad bit longer to display your GPS position but you'll gain a lot of battery life. My GPS is always on, sync everything including 2 different Google accounts (all at the shortest interval) and have the other usual things running, ie. Facebook, Google Voice, Weather Bug, Go SMS, etc.
You've got wake locks and need to determine what they are. Read this, it should help http://forum.xda-developers.com/showthread.php?p=31974989

If you don't want to root, there's not a lot you can do as far as wakelocks. However, I would download Macrodroid and set up some profiles that turn off everything (sync, data, wifi, bluetooth) when you turn your screen off, control your syncing to once an hour or hour and a half, and turn on your data/wifi when you turn your screen back on - or rather, when you unlock it. This simple task will take you less than 20 minutes and will save you hours of battery life. Like others said, disable GPS unless you absolutely need it. Also, I would turn off a lot of the gitchy features (air gesture, air view, multi windo, smart scroll, smart stay) all that crap that is cool to use once or twice but just eats your battery like crazy.
If you choose to get Macrodroid and want help setting up the profiles, let me know. Good luck. By the way, that doubled my battery life. Once I rooted, controlled the wakelocks and bought a zerolemon 7500 battery, I can actually get over 3 days of usage with something like 9 hours of screen time.
Edit: Found two pics to prove the above claim...
/!\FOUND ONE FIX FOR SCREEN OFF BATTERY DRAIN - BOTTOM OF THE POST/!\
Hello, and thank you for reading my thread.
1. Introducing of me and my problem
I am the proud owner of a SGS3, but I'm not english so excuse my poor level of speaking. Hope you can understand me. My problem may seem quite familar, but after hours of reading I still did not find anyone with the same problem than me (I read on german, french and english - especially XDA - forums without any actual answer). Like I allready said I have a SGS3 but I had a SGS2 and a Note 1 before. Being a "Flash-addict", and tired of TouchWizz, I flashed a lot of roms, and of course CM. And here is the problem : on every CM installation I have I have terrible battery issues. Here you may think "Pfff... another n00b who didn't read the fu***** manual. (RTFM -- joke -- understood ?) So let's introduce part II :
2. My config'
If my problem is in a new thread and not in a general "Problem" thread, it is because it seems very 'unique' to me. I have :
- GPS totally off (localisation OFF in settings)
- WiFi constant refreshing OFF too
- NFC and AndoBeam OFF even if I read it has no impact on battery life
- I ALWAYS enter multi-tasking and close all apps
- WiFi and Data OFF (Data always OFF because I only have 50MB of mobile internet / month (Viva la france !) - WiFi only ON at home )
- Brightness on AUTO
- CPU governor on 'PEGASUSQ' or 'POWERSAVE' depending on usage
- Talking about usage :
- SMS and Facebook
- Apollo (sorry but I can't live without a7x or black sabbath)
- Bash (u know that weird app that eats your time)
- Internet via Chrome or default browser (at home)
- That's all (+ some games at home)
3. What I have tried
On SGS2 :
- Buying a new battery (talking about battery do you know how do be 1000000% sure you have an original battery ? Some people say about the 'Made in Taiwan / Made in Korea" etc... but I have friends why an original SGS4 w/ battery made in Korean and some w/ battery made in Japan...)
On GN :
- Buying a new battery
On SGS3 (my current one, as you may guess)
- I read it is better not to use Titanium Backup so I tried without (sooooooo long restoring all apps from Play Store)
- I read extSDcard can cause problems so I put it away - do you know where you can unmount extSDcard in CM settings ? I know this option exists in TouchWizz based roms.
- I tried all the placebo solutions like wiping battery stats and so on...
- I installed Boefla (sorry for misspeling) Kernel and used an "Extreme Battery Yank" presset.
- Always upgrading to last CM Nightly (and re-flashing Boeffla Kernel)
- Flashing Mods for battery life
- See last part for SCREEN OFF fix !!!
4. Extra Notes :
- I have no battery issues on Stock ROMs and most of Sammy based roms
- I use a 1A battery charger, Samsung Official or very well done Chinese Export
- I have an extBattery with 2A charging possibility if needed.
- I really enjoy CM11 and really wanted to use it as daily-usage ROM (and not another KK rom like SuperNexus)
- My phone heats a little bit more than on Sammy Roms
- Current Widget says my battery status is Good (not dammaged battery)
- Oh and I have the stock 2100 mAh Battery
Best stats reached : ~5 % in one night (pretty good for me) and 3% in 30 minutes video with Wifi on, samsung headsets, AUTO brightness, PowerSaving governor and synchronisation and all the stuff off.
When playing games like "Worms 2 Armaggedon" or just watching videos on YouTube in HQ by charging the phone with my 1A charger, the battery level does not move (+1 % per 40 minutes)
Thank you for reading my thread and being so awesome in modding our devices !
Edited : Solutions found
Applied this solution (from Reddit) :
After much experimentation, I realized that it is not GP services app itself that is causing the wakelocks, it's the google search app pinging the GP services app for location all the time! Especially now with the Google now launcher, google search app is always or almost always active. This setup seem to create excessive wakelocks for NlPCollectorWakeLock from the google search app (Google Now), which in turn shows up as GP services wakelocks.
The solution is to take away 2 permissions: the Google search app permissions to keep the device awake, and access location. This gets rid of the wakelocks, and still appears to keep google now etc. functional. You can do this using App Ops from the play store (needs root), or if you are on custom ROMs, through "App Privacy" menu setting. Additionally you could also turn off location history and reporting, to be on the safe side. Google Now still works, but now without the wakelocks!

another method for same fix is this one :
I know a great fix, if this can get to the top it will help a lot of people. It requires the Xposed framework and the module Wakelock Terminator. The free version lets you block 1 app, and that's all we need. Open up Wakelock Terminator, choose to block Google Play services, and filter it with the following: NlpCollectorWakeLock NlpWakeLock CheckinService NetworkLocationLocator

Here is an additional fix (thanks to ivek81cro)
Ok, i did what post said and it didn't help, then i went into Privacy guard and set deny for Keep awake for Android system. Phone then cooled down and battery drain stopped. I didn't notice that anything else changed on phone (i think i didn't messed up anything with that). Today i returned permissions to default and all is ok now, no bat. drain or heating up.

I will upload images and links as soon as I am authorized
After this "fix", I had my phone SCREEN OFF two hours without loosing any percentage, with GSM on, WiFi, BT and NFC off. (just like during night)
Still looking for solutions for SCREEN ON, will tell you !
I also have the battery problems. No matter what I do it still drains fast. When I use original 1amp charger and do something on phone my battery actually dies while charging... No idea on what's going on

OK so I am not the only one, this is already a good (bad ?) thing...
up ?

-2% in 50 min. in standby, screen off, data off. :crying:
Tried everything.
Principal post eddited : Added a solution from Reddit (I can't post links because of XDA's security) for exeptional battery economy when screen is OFF :highfive:
I have same issue since yesterday, i9305, CM-11-20140531-nightly, com.android.systemui takes allmost 50%+ of battery and drains it 5%/h when in "sleep mode", testing solutions posted above, will tell you if it worked. Thanks

battery drain cm11
Try this...
Developer options enabled
Settings...performance...CPU frequency...minimum...make sure its set to lowest...tick apply on boot box.
After clean install mine was set to 2 knotches from max...set to 300 and immediately fixed all problems with battery drain.
NOTE III
SPRINT
CM11 (ALWAYS CURRENY NIGHTLY)
The below link shows the tip mentioned above about the privacy guard.
