Battery draining @3.5-8.0 per hour.

So guys i am on check rom v6 with fm kernel.
I even tried cf root kernel n francos kernel.
Modem is XXLA4
Flashed ics domination theme
So i installed better battery widget and cpu spy.
Cpu spy says my phone is in deep sleep mode 99% of time. And in better battery it has no wakelocks but still battery uses 3.5% approx per hr even when phone is deep sleep.mode.
Intresting thing is if i put my phone on charging. Better battery says my phone is gaining battery at 30-40%per hour. N then if i remove the charger even after 5min. Phone consumes 0.0% battery and 1%drop can last upto 10hours in sleep mode.
And then as soon as i run any application battery drop is 40%per hour and eventually comes down to 3.5-8% within 15min of closing every app and on putting phone to sleep mode.
Can somebody help.
Pleaseee... i am loosing 4% batery every hour. :-(
N even wifi is off.
Cell mode is gsm only
Brightness down to 0 and auto brightness off
Animations off
Pure black wallpaper
Vibrations off

Hi,
Just curious, have you turn off auto-sync and sync in background off as well?
Also, you may try to see what apps you have on your phone, (as you said your phone's batt drops at 40% when your using any app), some apps are really power hogs when it comes to battery drain...
just my own thought...

Yes i have autosync and sync off and set to manual or never.
Apps i mean like yahoo mail, tank hero(game) facebook app with wifi on. Or using zplayer and sometimes even sending messages makes batteru down to 40% per hour.

Uninstall Facebook app... there are many reports that the stock facebook android app consumes much power than just going to the internet thru the default stock browser and accessing facebook from there..., I don't know about yahoo mail app though but usually with wifi as well, the phone sometimes never sleeps (even if you have already turn off or shut off your wifi connection)
Try to see if you can enable Wifi Sleep policy in Settings>Wireless and Network>Wifi Settings>menu key>Advanced>
Also set Animations to OFF in Display and Screen Mode to Movie..
See if that helps a bit...

Wifi sleep policiy was set to never. I changed it. Thnx for the advice.
But still phone is consuming a lot of battery.

Maybe it's the battery that is faulty? Can you swap battery with someone and see if that helps?

Well, I think doing a Factory Reset would do the trick.. Try it and don't restore or install back most of the apps first, just observe if you'll still be getting the battery draining issue or not (perhaps an hour or two...... if not.. then, slowly install/restore one by one your app, and check on your battery after you install it...
I'm pretty sure, one or some of those apps (you have) are the culprit to your main battery issue...

I dont think so because when i unplug the charger and put my phone directly on sleep without using any app. The phone gives an awesome 1% drop per 10hour.
But as soon as i use a single app and then put my phone on sleep it gives 2%drop per hour.

Make a backup of your current ROM.
Revert back to stock GB + root & CWM. In the process, make sure you wipe dalvik, data, cache, and battery stats. Stick to something like LA4 or LA6 radio.
If the problem still persists after doing this, you know it's hardware-related. If it doesn't, it's the software on your current setup.
It's too hard to pinpoint over the internet as we don't know what apps you have going, etc.

Install badass battery manager, n check, if any perticular application sucks battery.
If not conclusive, try hard reset. Then full disharge n full recharge battery.

Android OS draining battery?

Well my nexus has been giving me 5 hours SOT for the longest time, but just randomly, it decided to start dying really fast. I checked battery stats, and sure enough, android OS is the killer here. I'm aware android OS drains are usually because of apps installed, but I haven't installed anything new or suspicious any time recently. I even did a full wipe and reinstalled the rom I'm running.

Are any of these apps known battery drainers?
Here's my battery shots.
Anyone know how to troubleshoot which apps are killing my system? I'm running CM 4/22/13 and franco.kernel r127 if that makes any difference.
Thanks guys!

If your phone has been on standby for that long then obviously androidos will be up there since nothing else has been working your battery. Post the pics so I can clarify this.

Nah because when it happened (at least for me) the battery drain was sudden and drastic.
All day Screen was at the top, then all of the sudden in the evening Android OS went from 15% to 74% in about 15 minutes.

Pretty much my scenario

android os thing happened to me, i think for me it was because it was trying really hard to connect and stay connected to the bad wifi at my school, turned off wifi and the drain stopped. not sure about ur situation though

This might just help you out. It'll show you any partial and kernel wakelocks and which processes are causing it.
I had this problem a while ago, so I did a clean install of my rom and apps and the problem was gone. If you can pinpoint the app that's causing your phone to stay awake, you can avoid having to do what I did xD

Really weird... this has been happening to me too, but not as drastic as yours (still a good chunk)
I just reflashed my ROM just in case that was the problem.
Also when I used better battery stats to see what's going on, all it showed me was the power manager thingy. Which showed me nothing.

That's all it ever shows when it comes to Google services jacking up the phone. Kind of convenient for Google since we can't pin down/point blame for the issue

Turning off WiFi when idle at school seems to have helped. I did notice that when I got to my house it seems the battery drain is more normal. Maybe it really is because the WiFi is just slow.

did you ever solve this problem? or find out what caused it?

I had a similar issue. My phone would not deep sleep. Yet things would work fine when I wasn't on WiFi. A reboot of my WiFi router fixed it.

I got the same problem here with my I9305 after updated to 4.3
It has a bit improvement after I disabled the ALWAYS WIFI SCANNING, and sync

[SOLVED!!]
i have this problem with my galaxy grand phone ,the battery discharges in 20hr , default OS was 4.1.2 official samsung , i changed my rom into a slim custom rom based 4.2.2 , but the battery has same problem again , Android OS battery Usage Was 80% !!!! and screen usage just was 9% !
my installed software :
Viber
WeChat
MyKet {Like Android Market}
Weather Widget
i used wifi 1-2 hour in a day ,
=================================
[SOLVE]
first go to Settings -> Developer Options -> Apps Tab -> checked Don't keep activities
set brightness to auto
then go to location services -> off access my location
then go to wifi -> advanced Wi-Fi -> keep wi-fi on during sleep -> change to Never
now go to application manager -> Running Tab -> Force stop some apps with extra ram usage like settings
my phone just uses 5% battery in 13hr sleep mode ; ENJOY!

I think if you only do this you will solve the problem.
At least for me my only problem with "Android OS" is when sleeping my phone and having "keep wi-fi on during sleep -> Always".
I have franco kernel and cannot check the kernel wakelocks but I test some days with CM kernel and didn't see any kernel wakelock that consumes too much battery... but maybe some of you have this problem: http://hardforum.com/showthread.php?p=1039838404

Wow, what a surprise... I solve my own problem with my last reply xD
I mean, when I installed CM months ago I select "keep wi-fi on during sleep -> Always" because I thought that if I don't do this I will not receive any notification. The fact is that when putting "Never" Android OS was CPU active mostly the 80-90% of time my phone was sleeping and Wifi ON and now with "Always" (or when plugged) has CPU active like 20-30%... AND I receive notifications also.
Probably when downloading a large data If I put my phone to sleep It will stop download, I didn't try.
One thing I don't understand is that when sleeping it doesn't use mobile data (as it says "Increases data usage"), even I have data and wifi on.
So, if I get notifications in both options ("Never" and "Always") and I get less battery drain with "Never" I prefer "Never".

You say you receive notifications even with the "never" option, but are you sure its not using your cellular data connection instead?

I've experienced similar problem with GS4 after 4.3 update
I've experienced similar problem with GS4 after 4.3 update
There is a bug in google backup service, google backup service acquires wfii connectivity lock and does not release it for hours which prevents device entering deep sleep and as a result drains battery. Fortunately you can disable backup in Settings->Accounts->Backup and Reset-> uncheck 'Backup my data'. This should resolve the issue ... after a full recharge monitor your battery stats - Android OS should NOT be on the top.

Sorry disabling backup didn't help - encountered the same problem. There is indeed a bug that some OS module that holds a wlan lock but it's not a backup service. I suspect that full charge triggers this flow. Device restart will temporarily fix the issue. I'll post if i will find the causer, sorry for mislead.

[Q] Big battery drain - invisible wakelocks

On stock rom I noticed that I have some wakelocks when device doesn´t go to sleep for hours. I wake lock detector I can ´t see any app (including system) that has more than one minute wake time but overall wake could be 3 hours.
So it ´s not app, it´s not system app, I also changed kernel, reboot phone many times and drain is still here.

once its awakened. it stays awake like 10 seconds. you can check how many times.
also you can check betterbatterystats. I like it better as it distinguishes kernel and partial wakelocks

I tried everything but can t find what wakes device. I know only that phone is waked for 40 minutes with 7 minutes screen time but it isnt caused by any app.

I prefer BBS for the finer details. You sir, have a rouge app or service.

Tried to freeze all new apps but still there is waking. Waking detector and gsam aren t showing any rogue app.
I suppose that Held wake time shouldn t be longer than screen time, or?

I would be over the moon to have battery life like that, 1h20 screen on time in 10 hours and still at 79%. I get nowhere near that...

You should check the "App usage" section to see what app or service is displaying high cpu usage and look at the details for that app or service to identify the wakelock.
I suspect the issue is network related. But I may be wrong...

I'd back stuff up and whack the phone with a factory reset. But that's just me, I'm a bit psycho like that

The main problem here is that in 10+ hours on battery, the phone is awake for over 6 hours. I don't think that's normal.

I did many clean installs and factory resets but there is something more. On PA kitkat rom I don t have wakelocks like this even with same apps.

try to go to a flex rom. if you like stock then that's close to stock but i havent seen any unwanted wake locks on the couple i have tried. i have a d800 with aeonflex and furnace kernel. when the screen turns off it literally uses no battery.

Same on flex. In fact flex rom was first rom which brought me to constant rom changing, reseting and testing where is problem. I am really desperate. Last thing which i can try is flashing maybe 10c or 10 a

Well, we don't know what was running behind, but with basic logical thinking 6hrs awake on 10+ hrs overall, we do expect ton of battery drop, right?
Here's my case, from 100%, fully charge, 2 minutes on call, 8 minutes screen-on time, what do you expect to see my battery level after 8 hours with 1% wake (meaning 99% sleep)? Ans: 51%. So how could it be 49% drop when only 1% wake? BBS, WLD found NOTHING.
What did I do next? Reboot the phone and I got 10x better on battery. Weird, indeed.

Maybe this will be helpful?

@kapybarus go to dialer, type 3845#*802#, go to Settings, Fast dormancy mode and disable it. While you're there, go to MLT test and disable that too. Reboot the phone and see if you'll have more wakelocks by system/radio like that.
Most likely you have fast dormancy enabled while your network does not support it.

Thanks, for now wakelocks are gone, hope it will persist. It is possible that these wakelocks starts when I changed provider few weeks ago.
I read that disabling fast dormacy is not good for battery (when provider supports fast dormacy) so should I switch to my previous provider if there were no problem?

If your provider does not support fast dormancy, it's better to disable it on the phone. If it does support it, it's better to turn it on. Fast dormancy itself is an efficient system, but if it's not available on your network, your phone will generate wakelocks trying to work with fast dormancy states and receiving no response.
Let us know if the situation changes

yeah try betterbatterystats, look into kernel and partial wakelocks

Battery drain when idle

Hi Guys,
I just got my LG G2 and so far lovin' it. I just noticed a battery drain problem though.
I left my phone at 87% when I went to bed at around 12am, this is with WIFI and Mobile Data off. When I woke up at 7:30am, it was down to 71%. I checked BBS and the number one item under Kernel wakelock was bam_dmuc_wakelock.
I've read multiple threads regarding this but have not found a concrete solution. One thread (http://forum.xda-developers.com/google-nexus-5/help/-t2688930) said that this is normal and some app may just be causing this.
Here are the current apps installed on my phone which were also the same ones installed on my HTC One X where this battery drain problem does not exist:
BBS
Dolphin Browser
Facebook
Instagram
LinkedIn
KK Keyboard
NBA GAME TIME
Olympus Image Share

Whatsapp
Youtube
Can anyone help me with this battery drain issue of mine?
Thanks in advance!

If you rooted, you can try Greenify to identify the culprit.
Maybe you can check battery settings to see what is eating it up?

bam_dmux is for mobile data so anything that keeps mobile data connection open it will show up. Stands for broadband access multiplier demultiplier.
so the problem in question should be simple, what app is continuously using your mobile data connection causing the bam_dmux_wakelock

The thing is, my mobile data is always off when I sleep. Is it possible that Whatsapp and Viber is causing this? I mean even though mobile data is off, can they be trying to look for a connection thus causing the wakelock?

ive had issues with facebook eating my battery on a bunch of devices. when removed i see a dramatic change in battery life. that is my experience, and may or may not be concrete enough to say that it would be the problem for battery drains.

well like they mentioned earlier you can try greenifying whatsapp/viber or other apps(different apps on a daily basis) to try and find out which app is cause the wakelock, but remember that if you use any of these on a daily basis then greenifying them wouldn't be a good idea(unless you only greenify them when you go to sleep and when you wake up you ungreenify them)

I'd probably try your suggestion about using greenify. I usually use whatsapp and viber a lot during the day. My only concern was the amount of battery getting drained at night when I go to sleep so I guess greenifying them at night does make sense.

yes but its not an actual drain you can see on the top it has only wasted 5% battery(in 7 hours that doesn't even amount to 1% an hour), even though its off it remains in a low energy state(idk why it does though) if it were actually draining battery then the cpu time would be almost the same as awake time(somewhere around 5 and 6 hours) and percentage drain would be higher but I have noticed that after about 2 months on kk(for me atleast) I had started using Bluetooth a lot once I got kk whether to stream music or connect controller to play emulators my Bluetooth doesn't false positive anymore instead it either shows the actual time it was used for(usually a couple hours every day sometimes 3 or 4 out of lets say a day I got 14 hours total use) and another thing I noticed is if I leave it off it will give me the false positive or if I leave it on all day and let it connect/disconnect to the different devices gives me actual usage time

Sorry for my question, but how do I do this?

to change kernel speeds you need root/custom kernel and I don't know how to do the battery calibration test

I think I found the problem.
When I leave my phone on during the night, I turn mobile data and wifi off, but my connection is still LTE. I was noticing about 10-15% drain as soon as I wake up. What I tried was to set the phone to just use 2G (GSM), still leaving mobile data and wifi off. I woke up this morning with just 3% battery drain.
It's weird though because I get very good LTE reception so I don't think that a poor LTE connection was causing the problem.
Does this mean that LTE really consumes that much battery?

Android System Battery Drain

Anyone else experiencing a battery drain ~ 28% Android System usage and 23% screen on time (~4.25 hours) with 20% battery remaining. Any solution to this? Probably a wake lock?

Yes battery drain alot
The only solution work for me is turn on upower saving
If you have rooted u cant disable wakeclock service. You can find in forum

I disabled the s health app which has helped, still seeing around 20% usage from android system though.

I bet that you have Dropbox sync on. I am not talking about uploading new pictures to Dropbox automatically, I am talking about ur phone downloading all your preexisting pictures from Dropbox. This stupid feature is on by default and killed my battery until it was done syncing. I have since switched off this stupid option. It shows up as android system drain because it actually unrelated to the Dropbox app. It's your gallery app that's doing all the downloading.

Interesting... I do that have on, but I would think it be done downloading now. I have my Note 4 for ~ 3 days now and I have a fairly fast internet connection.

Anyone still using Greenify out there?

on my device disabling location reporting seemed to help a lot with the Android system battery drain

I use DU Battery Saver to turn off all apps and network when screen is off.. also, you can disable apps from running in the background when the screen is off too.. I don't have the screenshot, but I got about 21 hours with 5 hours display using this method.. I'm also getting a 4500mah battery too.. so hopefully that helps.. Also, I tried going into 'ART' mode and found out that the DU Battery Saver Widget went up by 2-3 hours.. so hopefully Lollipop can help extend the battery too.. I found out that under 'Location' in the Settings you can use 'Power savings Mode' for the GPS, and also turn off the Google Reporting and Location (on the bottom)..

I got my phone two weeks ago but i just started having this problem yesterday. I went to turn off location reporting and under recent location request, i saw Unified Daemon and it had high usage. Prior to having this problem Unified Daemon was not in the list. Could this be what's causing my problem?
Edit: I hit force stop and turn off and its now out of the list. I'm going to keep watching it to see if this fixed the problem.

I'm on n910c, Battery life is quite bad the same as on my 2 year old note 2. I guess only root can help...

On mine, I get an average of 50% deep sleep and 50% at 300mhz with "msm_hsic_host" as the main culprit.
Weird. Monitoring my apps, none of them use wakelock more than seconds per hours.

Kinda strange - I get 80% deep sleep.

are you referring to the "device idle"? haha, thanks, so I can do a comparison too..

No, I'm talking about Deep Sleep as measured by CPU Spy

What does he do, the daemon?

ok well, unified daemon was a problem but less than this msm_hsic_host wakelock thing.
well, resetting the apnand made the wakelock go away...
weird but now i get 80% deep sleep and battery drain looks normal now.

I saw somewhere that it has to do with weather and news updates and since disabling it my weather widget is asking me to tap to add a city.
