Sorry if I've missed something here guys but I noticed mention of the Bluetooth wakelock bug on KitKat builds. I had it too within hours of flashing it I had over 1 hour odd of keep awake in battery stats.
After going into Bluetooth and enabling it then disabling it, it still hasn't increased it seems to have stopped for now. Can anyone replicate this or explain this? I haven't had time to grab a logcat and look at it yet I'm at work currently.

Read something about this, somewhere.. if only I could remember now. In KitKat, Bluetooth isn't actually eating up the battery when it's not being used.

But its visibly keeping the phone awake. So it must be using it I never had it enabled before it appeared in battery stats.

I posted data thought about this at another thread where what I think is that just WiFi in 4.4.2 Bluetooth is always on although disabled but it should not be consuming battery(thanks to the low energy) unless it's connecting to other devices in fact I actually tend to use Bluetooth 50% of the time to play games with my moga and music in the car or with my deck at home and still get 15 hours easy

Yeah I spoke too soon its updated to 9 hours keep awake now but I have 3 hours screen on time and still at 50 percent battery so I don't think its actually using much if anything

Hello-
Ever since I updated to 4.2 and especially 4.2.1, battery life has not been the same. Today I went from 100% last night to 73% in 22 hours just in standby. I didn't change any settings that I can remember. Can anyone please help with this?
Thanks,

I had the same battery issues on 4.2 in standby...even with wifi disabled. I ended up flashing back to 4.1.2 and battery is back to normal. To me 4.1.2 is more stable and much smoother. Hopefully Google will fix these issues in the next update.

I noticed that a large portion of the battery is being used by something called "Media server" Any idea what that is or how to turn it off?

I'm also noticing the same sleep mode battery drain on 4.2.1,around 1% per hour..
I need to root my tablet to downgrade?

Use media scanner root from the play site and disable the media scanner. Then this battery drain should reduce.

I think in my case most of the battery issues was from the device being new and the software stats still needed more time to be accurate, that has happened to me on my Sony tablet also..
Now I can see some real stats as I use better battery stats app for keeping track of the battery.
I use my tablet as a use when needed device because it's not my notifications device that is always connected, for that I use my smartphone. That said I turn on airplane mode when I'm not using it and sync when needed as well.
Só when my Nexus 7 is in sleep mode it has very few apps and services running other than the system ones.
So the stats I came up with are:
1% in sleep mode with airplane mode on and Google Now and Location History turned on..
And..
0.3% in sleep mode with airplane mode and Google Now plus Location History off..
So for me no Google Now as I don't need that much.. It lasts 3x more in standby without it... And the truth is, in my country Google now for me isn't that useful as it is although I'm sure someday will be..

It's strange...with stock 4.2.1 no root I haven't any battery drain... 0.7% /hour with wifi on and sync enabled...In the battery stats, even if in a hour i turn on the display on a minute, the display takes at least 40% of battery...
I've seen people here and there say they've seen this too, but no one seems to have an answer. My battery isn't lasting until work ENDS, a far cry from when I used to plug it in after work, at home, at 20-30%. It just randomly started happening.
Noticed this on both 4.2.2 and 4.3. I've tried .48 radio and .83, stock and PA, stock kernel and Franco, heard it's common on CM also.
Anyone actually know anything about this? I'd love to last an entire day not having to turn off sync when I'm not using my phone, and other battery salvaging methods.

your android os looks normal. seeing that you didnt use the phone much, your screen on percent is lowered. since your screen on percentage is lower, all others will appear higher than you would think they should be. but if your screen was using 50-65% of the battery as it would for normal use, then your other percentages would be lower. anyways, your android os is normal. what i would look for is an app in the background behaving badly, or disable a notification or two if you have many. if you have root, i would install greenify and then greenify a bunch of apps.
my android os usually hangs between 4-8%, but my screen is usually around 60%(with heavy use).

i never look at wakelocks, that is how our device is supposed to work. granted, occasionally an app will create a wakelock that gets stuck, but thats just bad coding on the app by that developer. watching wakelocks will waste more of your time than its worth. take control of your apps instead, dont let them run rampart.
Neither BBS or Wakelock Detector is helpful in diagnosing Android OS battery usage. Most of the time it shows as PowerManagerService.Wakelock in Kernel Wakelocks, and pages from google state that is it a sum of Partial Wakelocks adding to PowerManagerService.Wakelock. But there was one time I had a 15 hour wakelock from PowerManagerService.Wakelock and looking in Partial there wasn't anything really significant, most entries being 20mins or something at the top of the list, 10 minutes on the next, and so on.
Whatever it is, it's particularly bad on 4.3 both on my Nexus 4 and Nexus 7.
So I listened to some music for roughly 20 minutes in the car. Set my phone down to watch TV. Came back 45 minutes later and it dropped ~25%. This is WITH 3.5 hours SOT. android somehow still takes top spot. Help?

Everything was fine after the 4.4.2 update until a couple of days ago. I noticed a heavy battery drain during the night - approx. 20%. The conclusion I made: Android OS is back. The WiFi was on, but the router was off, so I though it might have something to do with it trying to establish a connection.
This past night I turned the WiFi off and left the 3G on. 10+ hours of wakelock from Android OS and 30% drain. So, what am I missing here?
The worst part is that those f"%^* from Android developers team has disabled any reporting from the running processes in the latest version.

You can use the stock google app to find what google app is running during the wakelocks. Just go into Settings -> Apps -> Running tab and see what google process are running. Then download and use "Disable Service" from the playstore to find and disable the suspect google apps.
My phone would stay wakelocked after a call or gmail check all because of gcm_google service. I disable it under Playstore services using Disable Service and my google wakelocks went away. Worth a try.
same problem here
misuse of wake locks can easily lead to energy waste
"Android os" usually is the kernel while "Android system" is, well the system. Try changing kernel, it fixed the issues for me.
Hit thanks if I helped you
Stock G2, AT&T. Running KitKat latest update.
Since KK arrived, I've had major battery drain by bluetooth. I leave bluetooth off, but it is always the highest power user in standby. Anyone else have this, or know how to fix it?

the way I see Bluetooth is now like wifi even when it's off it's on but since it's in a low energy state it really shouldn't be draining your battery I've easily gotten 15+ hours while actually using the Bluetooth to play games with my moga controller and using my deck
I have the same issue.. im stock t-mobile on kit kat... and im currently getting the same amount of battery i was getting on my lg nexus 5.. which kind of sucked.. I dont think theres a fix yet

Maybe Phone Carrier
I think it's maybe related to your carrier too. They change something in the ROM to make compatible with network then release to your phone. For International and Korean Version is ok. But can you try to reset, if the problem still exist?
I have sprint and have been dealing with same issue since kk update. I don't even use bluetooth, always off, but yet saying keep awake 5hrs on a battery cycle.
I only experience it when I have wifi on at the same time, its weird.
From my experience on my phone, it's just a wrong reporting. Even with BT allegedly draining according to the battery stats, my battery life is still the same as before.

How can I tell if I have a wake lock or a battery issue? I have wakelock detector installed and I check my battery stats. It says in the lat 3 hrs I used 28%but I haven't done that much. I probably used the phone for about 15 min total . resetting didn't help. I left home at 7am with 100% its 1140am and I'm at 65%. I know Kik is running but I havent used it much. Also my on screen time is almost 2hr hrs but I haven't been using the phone. Its sitting on a desk and the screen isn't turning on .

Kik is first thing I would remove.
I had installed Kik on all of my Android devices at home to kik with my daughter but this app was a battery killer. Happened on every device I installed.
I cannot believe that the Kik's creator hasn't fixed this issue yet.
Anyway, stop using Kik since.
Also
a. try to disable Knock On/Off feature.
b. try not to use Location Access
When u say location access you are referring to GPS? I have everything on this phone turned off , I greenyfied just about everything I could and I froze everything that's been listed in debloat threads. The battery life was pretty good before the past 3 days and I haven't installed anything. Reboot doesn't help

Also is it possible for the battery to drain out quicker after rooting, greenifying and freezing things because whenever I do all this on a device it seems like the batteries drain faster than stock

For the past few days I've been noticing that the battery is draining terribly fast, a quick check in the battery details page revealed that my wifi is being used throughout the time my phone is on, even though the wifi is off in settings and quick songs notification panel. How's that possible?. Is it some app which is using the wifi?. But can the app use the wifi which is off? . My S4 is a GT-I9500 model running 4.4.2

WIFI is always ON in your example, but it is not the issue you are looking for.
You have to find what application ( or wakelock) is running in background when your graph is in AWAKE state.
Drain? What drain? There is absolutely no drain visible on the screenshot. Your screen uses power. That's normal for a screen to do.
Smart Stay and adaptive (screen mode) drains battery a lot so you should consider disabling it.
I've turned off adaptive display, ill check if it will improve the battery life. Thank you

As u can see from this graph, my phones charge came from 95 to 15% in just 7 hours, with hardly any usage. Is this issue hardware related, could a faulty battery be the culprit. My phone is just 3 months old and still under warranty, should i consider replacing it.
