Hi All,
A few weeks ago I installed Cyanogenmod 10.1 20130630 nightly on my Everest Xoom and have been very happy with the Jellybean features and performance.
The one problem I have had though is heavy battery drain. Before on ICS stock I would charge the Xoom and get around a week standby with light use between charges (I only use the Xoom no more than 20minutes a day really). Since installing Cyanogenmod, I cant get more than 2 days standby. I have set WiFi during sleep to never and I have tried charging it fully then not touching it besides a screen unlock for test purposes every day and cant get more than 2 days. Any suggestions how I can get more standby time, or a different ROM more suited to my occasional use?
Thanks!

Have you checked your Battery Settings (In Settings) to see if it is a rogue app(s)? If it is, you can either uninstall that app or use Greenify (http)://forum.xda-developers.com/showthread.php?t=2155737 to hibernate it and prevent it from wasting even more battery life. If you can't find anything abnormal in Battery Settings, install Wakelock Detector (http)://forum.xda-developers.com/showthread.php?t=2179651 and check the app the next day. Anything draining the most battery life in standby should be on the top of the list. You can then uninstall that app or Greenify it as I mentioned before. Tip: If you install Greenify, check in the settings if auto-hibernation is turned on and if it isn't turn it on. In the widgets drawer there is a Greenify widget that you can tap to hibernate now if it is on your homescreen, if you want to hibernate apps immediately.
You can also intall SetCpu (http)://forum.xda-developers.com/showthread.php?t=505419 to save battery life. Go to the profiles tab, tap add profile, change the profile to Power Off, Max to 456000, Min to 216000, and change the scaling to powersave or conservative if you don't have powersave.
Hi,
The battery life of my Nexus 5 has taken a dramatic hit since the 4.4.2 update. I think the culprit is Android System but the GSAM battery graph seems to suggest that the culprit is Android OS kernel. My Nexus 5 is on 4.4.2, unrooted, stock ROM and the build no. is KOT49H.
In short, my phone does not seem to have a wakelock issue but I can't verify because 4.4 does not allow wakelock access without root. It sleeps fine at night and in daytime when it is not in use. I only lose around 5% or less overnight with 2x battery turning off the data connection and only turning on data connection once every night. The problem is the Android System which drains at least 17% (sometimes 25%) of battery everyday and routinely sits on top my of battery usage chart with or without me actually using the phone. My usage per charge is typically around 6-7 hours with around 1 hour 45 minutes screen on time. I had extraordinary battery life before the update to 4.4.2 (lasting more than 1 day with over 3 or 4 hours screen on time). Now my battery life is completely shot. The battery graphs attached already represent one of the better days. Some days the Android system will drain at 25% or more. You will note my phone relatively slept fine without draining at night in the first 7 or 8 hours and then the battery drain started to take a nose dive after I woke up. I feel that whenever I start using the phone (with the screen being turned on), the battery drain will occur. My observations are as follows:
1. I use LTE but the reception at my home and work for LTE is not good so the radio jumps between LTE and H+ from time to time however I do not think the radio jumping contributes that much to the drain. The drain stays the same even when I am at a place with good LTE reception. I use wifi at home but i cannot connect to wifi at work (which sadly is another issue). The wifi is always off unless i use it at home. I do NOT have wifi scanning in the settings. I have wifi battery optimization on. I never use bluetooth.
2. My google now is off. My location setting is completely off with no location reporting etc..
3. My Google + auto back up is off. I do not use Facebook, Facebook messenger, Instagram, snapchat etc. I mostly use Feedly, Whatsapp, Gmails and look at stock quotes every day. I seldom take pictures, videos or listen to music.
4. I only have one widget dashclock widget. I have removed feedly and stock quote widgets from the home screen but they don't seem to affect my battery usage that much.
5. I use Automateit but only have a few rules such as setting vibrate on weekdays etc.. I do not have any profiles which are related to GPS or location which i understand would drain battery. I also use Dynamic Notification, Light Flow, Lux, Nova Launcher, Notification Toggle and the memory in general is always below 65% in the background. I also use 2x battery to save battery which is set at switching off data after I turn off the screen and it will only turn data in the background every 10 minutes.
6. I have tried safe mode and 9 out of 10 times the Android system drain remains the same. The only way to lower the Android system drain (albeit temporary) is when I turn off the phone and plug it in for a charge, then turn it on when it is full and still plugged in. After I unplug it, the Android System drain will lower to say 7 or 8 % but it will slowly creep back up to 20% within an hour or so.
7. The CPU usage overlay routinely has 9 + readings on the top when the screen is turned on (but with no app running). I think it means very high CPU usage.
8. I do not think Feedly is causing any problems. I deleted the app and the drain remains. I also do not think GSAM is that useful as pointed out by another member here. It points to one app. You delete that app and then the drain remains it will point to something else.
9. I have been using Greenify (non-root) but it does not seem to help with my battery drain as the drain might be caused by system apps or processes within the OS.
I don't know what else to do and this problem has been troubling me for more than 1 month now. Please help !
Update on 24/2/2014:
I have given up and factory reset my phone. After I reset my phone, the apps were installed via Google Play automatically. I also switched to ART. It was fine initially for at least one day. The apps were there but I did not use or enable most of them as I wanted to transfer all my data and tweaked the settings in one goal. I mostly just used Feedly, Whatsapp and Maps for navigation. Even with Maps and high accuracy GPS on, the Android System would go below 10% even though it would temporarily increase to say above 20% during navigation. This morning, I thought the battery seemed ok so I enabled Lux, Dynamic Notifications, Lightflow, Automateit, Nova Launcher and restore the settings to most of the apps.
The Android System drain came back within 2 hours and hit 25% of the total battery drain. My phone's battery dropped from 100% to 40 % in less than 5 hours and the screen on time was only around 1 hour! I never did any battery intensive actions. The most was turning on the phone to check my battery and whatsapped less than 10 messages back and forth ! Since the drain re-appeared, I have turned off completely the location setting, Google Now, sync for Google Plus, auto-backup for Google Plus. I have removed all widgets and disabled Dynamic Notifications, Nova Launcher, Light Flow, Lux. The drain still remains the same at 23% or more.
This is driving me absolutely crazy and I am sick and tired of spending so much time and energy on sorting out the cause for drain (and to no avail!) I spent a lot more time on trying to fix the phone than really utilizing the phone for my benefit !! I just sent an email to the Google tech support and hope they will help instead of sending me generic self-help sheet. Thanks all for listening and trying to help. I am just really disappointed with Google this time.
Use bbs to get wakelock info.
Feedly has got to go too

Thanks for your reply. My N5 is not rooted so I do not have access to wakelock stats anymore.
I have removed Feedly but the android system drain persists.
Not a lot that can be done without knowing the cause. Consider factory reset?

I am hoping I don have to resort to factory reset and can wait for the 4.4.3 update but I guess my patience is running out.
Thanks for your help.
My missus' LG-P880 has exactly the same problem. Just started happening one day. It seems to be wakelock locator alarms according to bbs but there doesn't appear to be any reason for it. Its been driving me mad too. Luckily tho she's rooted so using app opps i disabled Google services location and it's kinda helped

Did you try another kernel ? When I changed to franco kernel, my battery life is better.
having weak LTE signal kills the battery but it should not be this bad.
Maybe you should try a factory reset and see if the problem still persist, if not then you have an rogue app somewhere.
You can use the process of elimination.
Start with disabling Dynamic notifications and Light flow as those have high potential for battery drain.

Restart your phone in safe mode, and see the battery drainage...maybe it can help you.
It seems good for me

I had this same problem the other night. Get app ops starter from the play store. In there turn location off in Google play services and android system. Note, this may impact other apps. I don't use any that I need location for so it works for me.
Sent from my Nexus 5
I had a similar issue as well. For me I turned off a couple things and it really helped:
1. Turned off Cerberus, I believe checking location too often or incorrectly or something.
2. Turned off Account sync for Play Newstand. Noticed when a sync would occur, it would hang on Newstand for much too long which I think was waking device and keeping device awake during it's long syncs. Everything else would only take a min or two total.
3. Set G+ photo sync to only sync when on wifi and charging.
4. Removed Yahoo Weather app. Noticed yahoo weather app staying alive a lot too.
5. Removed Whatsapp. Probably unnecessary really, but any of those messaging/weather/location apps that I don't use often (if ever) I removed to make sure they weren't checking location in the background.
So far, I'm at 78% battery today when I would have been at around 30-40% usually, so that combo has made a huge difference.
It's going to be different for everyone I think, but basically just make sure you don't have any excess apps checking location in the background. And at least for me there seems to be something wrong with Play Newsstand sync hanging for long periods of time.
Yea... Even i had the same issues... Latest version killes ma deep sleep mode nd also some of a rules disappeared....
I was having similar issues and was able to narrow it down to syncing Google Services...
I found that often times Google Drive would get hung up when syncing in the background and chew up my battery.
What Google Services do you have set to auto-sync? I would narrow it down to the ones you only really need to have synced in the background and have the others sync up for you when you open them.
Also, in regards to your LTE/H+ signal, have you tried to flash another radio to see if there is any improvement? A poor signal can have a pretty significant impact on battery life as well.
Lastly, as mentioned by another user, Better Battery Stats, though requiring root, will make it a lot easier to track down the culprit of the issue if it indeed a rogue app somewhere.
Try different keyboard. I've a suspicion that latest Google Keyboard is the culprit.
I was having some unexplainable with BBS (no locks, etc.) battery drain. Which can only be resolved (though temporarily) with reboot.
So, I installed alternative keyboard (Swype in my case) and using it. So far, second day I don't have battery drain.
Update
Please refer to the OP for update. Thanks all.
battery after reset
After a second factory reset, I did not install a lot of the apps which I suspect have something to do with my drain - including Swype, Dynamic Notifications, Nova Launcher, LightFlow, Task Manager, 2x battery, Lux, Notification Toggle, Dash Clock, Automateit. I have also set my location to device only with no location history and history. I have also disabled Google Now. I have not restored my photos, music and videos to the phone yet. I have disabled sync for Google Plus, Google Drive etc.. I have also disabled auto back up for Google Plus. I am on ART.
The battery life (with around 25 % left) was around 6 hours 30 minutes or a bit more but with close to 2 hours 40 minutes screen on time. The screen was the biggest draw. Android system comes in second with around 13%. This is obviously better than before where I managed to squeeze maybe a hour or 30 minutes more but with 2x battery turned on in the background. I mostly used the phone for battery checking, whatsapp, Feedly, web surfing. I played games for around 20 minutes. I was not on wifi most of the time. Is this battery performance normal?
Thanks in advance.

I have reset the phone three times. After the third attempt, the battery drain for Android System would go back up to 20% plus. By the test of elimination, I thought I narrowed down the possible culprit to Light Flow and Dynamic Notifications. I uninstalled both of them but the battery drain remained 20% plus.
Google was willing to replace my device. I asked them whether the battery drain is likely a hardware or a software issue or a combination of both. They said (to my surprise) it is hardware issue. It seems they have come across quite a number of similar cases. I always thought it was a bug within 4.4.2 or in the google apps such as Google Play Services etc. and could be fixed by a patch or something. The phone also means a lot to me as it was a gift from my gf. I just don't want to go through the hassle of replacing the device if it is a software problem but I guess I am running out of choices unless I decide to wait for the update. What do you guys think?
It's definitely not a hardware issue. If you Google it there's threads all over the place with all different makes and models of phones having the same problem and no one can figure out why, apart from it definitely seems something to do with Google services (GmsCore.apk)
Your best option is to root your phone and use app ops and turn location access off for every app that doesn't need it. (pretty much everything apart from maps and weather apps)

Hi Guys,
My bluetooth is keeping the device awake all the time since the past one month. Even if I disconnect my G Watch, bluetooth drains the battery. Waited for Marshmallow and installed it yesterday after formatting the phone but it bluetooth is again at the top in power consumption in the battery stats and keeps my Nexus 5 awake all the time. It used to work really well until last month.
Are you using a 3rd party app to manage your BT?
You can still use an app like Tasker to only enable/disable BT when needed.
I uninstalled all the apps and reinstalled everything one by one. Android Wear app was the culprit (even though it never came in the battery stats). Now I don't know what to do with my smart watch/how to use it. It's useless without that app.
try clearing the "app data" for android wear
Hello everyone!
So this thread is for those guys that are still having the standby drain even after trying everything and got no help.
My Device Is not Rooted​Since last 2 weeks my device was having super standby drain and I couldn't help that.
First I thought that it was due to the battery wearing out. But I had this phone(exynos version) for around eight months and that is not enough time for the battery to drain out fast. So I started looking for the fixes in the xda threads but none of them had a mass effect on what i was suffering from.
Then I read about that app named the "Better Battery Stats".
https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats&hl=en
I used this app to monitor the usage that was being done by different apps.
Most of the battery i.e 61% was being consumed by the apps that were running in the background. And the second big consumer was the android system. So as was mentioned in most of the posts what I tried.
1) Settings> Display> Resolution> Fhd to hd
2)Settings> Device Maintenance> Battery> Save Power and All apps put into always sleeping apps.
3)Setting> Connections> Location> Google Locaation History and disabled it.
4)AOD Disabled.
5)Sync Disabled.
6)Wifi> Advenced> Keep wifi turned on while sleep and set it to never.
7) Reset> Reset network settings
8) Boot into recovery and wipe cache patition
9) Reset factory data(Wipe everything).
And after doing all these steps nothing much changed my battery life since when i after resetting my phone again updated all apps from play store and resetting battery got an SOT of around 3 hours.
Then I again started searching for the problem.
I installed the accuBattery app from play store.
https://play.google.com/store/apps/details?id=com.digibites.accubattery&hl=en
And saw that phone was not entering deep sleep for hours that was causing the standby drain!
The major reasons for the drain were.
1) TOUCHWIZ HOME!
2) Google Chrome.
3) Facebook app.
To fix that I applied Lawnchair as my default launcher.
set the theme to dark. Disabled the location permission in the facebook app. And disabled google chrome.
Other settings that also helped were
Change the resolution to hd. Disable google location history.
And boom.... It worked Like a Charm....
Now to add an extra something to the battery life i switch to MID Power Saving mode. That Also helps alot when phone is not being used as it stops background data usage by apps.
Now the average sot that i get from my phone is around 6 to 7 hours.
And the phone sleeps like a baby. 5% Drain in 10h and wifi was on for the whole night. Deep sleep for 9h 41m.
PS: I use most of the time my phone for gaming and heavy usage.
Hope this will work for you guys too.
Screenshots Are attached for the proof!!
Thanks for this man
How are your notifications? I'm having a lot of trouble with delayed notifications, emails/messenger/etc just wake up when I take the phone and I don't even have to wait more than 5-10mins for what seems to be doze to kill everything.
I get whatsapp calls that I miss because the phone never receives it.
And STILL my battery life is far from great.. borderline bad I'd say. So sad
In settings go to device maintenance and hit battery you'll see an option for "always sleeping apps" enter any apps you don't want to run in the bsckground, which will probably be most of them. Saves a lot of data and a lot of battery.
Normally when I put apps manually in deep sleep they don't do anything , run , wake up or use background data, send notifications , more so when their mobile data is restricted as well as their background activity. The highlighted even show as "manually disabled " within the apps menu. Yet they are showing up usage in background process within GSAM monitor.
Any ideas lads?
Edit. I checked their status under Dev menu, they were set to working _set , changed them to Frequent and will monitor.
It's a bloody joke , that deep sleep or sleeping apps setting under device care.
Just checked a few of my apps that are set to deep sleep aka manually disabled. Yet within Dev menu, their status is Active under standby apps.
Here's one example.
I checked mine and the apps are not "disabled" when I add them to deep sleep. I can still open the app, which would be impossible if the app was disabled.
I wouldn't trust the dev option as an indication that the app isn't sleeping (aka running in the background)... I have apps listed in mine that I haven't used yet, and there has been zero activity in the apps at all (battery use or otherwise).
Double check the battery use of the app and see if it is running in the background.
**Never mind, just woke up here and saw your first post edit. Hopefully the issue gets resolved for ya

Yeah you're right. The dev option status for those apps running or not appears to be variable ,.changing them changes them back to whatever they want to be i believe.
I was just shocked ( not really ) I had those highlighted two or three apps in deep sleep status via the battery care menu, yet when my device was left sleeping and untouched for 2 hours I opened GSAM and it showed those very same apps as being used in the background as the top five usage lol
I use Nap Time by Francisco Franco to put the phone in a deep doze. Been using it on all my phones for several years now. Just need a couple adb commands for it to work on an unrooted phone.

I'm good with 0.5 to 0.4% usage per hour in standby, however I might look into that in the near future if it may improve them. Current issue on hand if at all any might be SOT. I'm currently averaging similar figures to my last Samsung device which was an S10+
I guage all my devices battery performance by how much screen on time I can attain for around 40% of battery consumption. Currently averaging 4.5 hours. Was hoping for 6 plus but they might be over optimistic considering the 4370mAh battery.

With Nap Time I only lose 3-4% in a 12 hour overnight. I also have a lot oy Samsung bloat disabled too.
