I've experienced this NFC battery drain problem in the JB versions and now the KK versions of almost all the ROMs including stock ROMs. Deleting (or just restricting the permissions) the nfc.apk from ./system/apk/ folder did the trick for ROMs up to CM 10.2 (or for other JB based ROMs). But in KitKat based ROMs it is no longer a solution. Once you delete the apk or restrict permissions, Settings will force close when opened. The screenshot given below shows the battery drain happened in one night, everything (data / wifi / location / sync) in turned off state. The installed ROM is CM 11 M6.

The NFC option is grayed out in Settings as seen in the screenshot and it seems it's permanently turned on.
I've waited for the device to complete a few battery full cycles with CM 11 M6.
Tried almost all so-called-solutions, but none of them really helped.
The problem is there in both Dalvik and ARC run times.
Went back to the official ICS ROM and the battery lasts for almost a day. So, the issue is not with the battery.
A possible solution is to bring back the ability to disable / delete nfc.apk without causing Settings to FC. It will be great if somebody can do a flashable package to make this happen. :fingers-crossed:
OR
Is there any other possible solution for this? If there is nothing else, it seems like I should go back to JB ROMs.

I have an Xperia L, it has a decent battery backup but it's been worse lately. It was fine a few days ago. This is what battery stats show.
I know there was a mediascanner bug in 4.1.2 and I even knew the solution, but since I'm not rooted, I can't do anything about it. Can anyone help me with a solution which doesn't require rooting? :\
This wasn't happening earlier, could some app be causing it? I deleted most of my apps because of the horrible backup I started getting suddenly.
I'd get around 5-6hours of screentime on one full charge but now I can't manage more than 3-4hours. I have minimum apps, no FB app.

Did you try stamina mode?
Do this
1)Try a factory reset
2)Stamina mode
3)If still problem goes on, take it to the service cetner

If you are getting issue with numa's 4.0.4 rom then try another rom.
There are other rom I think that will fine on you phone.
Did you fix it yet?
It could be a rogue app you installed. Try using apps like Gsam battery monitor, Batter Batter Stats, System panel, to find the culprit.
If that doesnt work try Wiping Data and Cache and flash Numa again.
Ok so I'm getting this spam of errors for the sensors. While the spam active my sensors do not work, first thing to notice is the auto rotate. Then I used GPS Status and Androsensor apps and they both do not get a reading from the sensors. Now I've searched almost all of the interwebz but I can't find anything related or somebody who has found or understood this Logcat. This happens with stock kernels and custom kernels, stock ROM and custom ROMs. On some customs kernels, once I flash them it never even starts working.
If somebody has the knowledge here to interpret the Logcat and help me pinpoint the issue that would be much appreciated.

I honestly have no idea. I toggle the autorotation on and off but it does nothing. If I entered in the terminal emulator:
su
stop sensors (it stops spamming)
start sensors (it starts back up)
OK so I have an update to this. Flashed back to stock 4.4 and everything works fine even with custom kernels that never worked before. However if I update to 4.4.2 (stock or any custom ROM except CM or CM based ones) it breaks and stops working. On CM and CM based ones it works but without the custom kernels since I use Franco kernel and it is not compatible.
Anyone have an idea as to what could be the cause for this to happen? What is in 4.4.2 that is breaking the auto rotate and the rest of the sensors.
Hi there,
Over the past week or so I have noticed that my battery is going down a LOT faster than usual...
The culprit is "gpsd" that is using upwards of 30% of my battery every charge...
I have looked through everything that uses the gps and it's all either off or not using it.
How do I find out who / what is keeping gpsd going and make it play nice, or die?

Hopes help.

Definition - gpsd*is a daemon that receives data from a GPS receiver, and provides the data back to multiple applications such as Kismet or GPS navigation software. It thus provides a unified interface to receivers of different types, and allows concurrent access by multiple applications.
Workarounds - Look for every GPS associated application on your device. Make sure to switch off GPS.
Go to Settings, then to Application Manager or Apps. And find the GPS associated apps, open them and force stop them. Sometimes they auto run and can cause battery drains.
Tell me how this goes for you.

All apps that need location services disabled / uninstalled and it's still there...
Okay...
Just wiped and re-flashed rom... no apps installed aside from BetterBatteryStats and GPSD is still there...
Maybe time to find something other than Omega
Hi, I need help on this. It has been days since my battery has gone haywire and I don't know what happened. I just saw that my WIFI isn't turning off even though i toggled itoff in settings/quick settings. I thought maybe a simple reboot may fix it but no. I came from CO12 to Exodus to Bliss but all have the same problems. Wifi isn't turning off! All my settings are stock. Kernels are stock also. I'm getting an average battery life of 3 1/2 hrs SOT which is awful for my usage. Also AndroidSystem and OS is killing my battery but I disabled Google PlayServices which should help. My only concern is the Wifi not turning off. Pls help thanks

Hi.
I use this app wich does only cut on and off the network: https://play.google.com/store/apps/details?id=com.a0soft.gphone.aDataOnOff&hl=en
(you can also apply a screen filter to help stop battery drain)
But I doubt its your only problem... I tested with and without the app, and the difference is almost not visible. Also, my wifi (when app off) is in third place on battery usage, and I have at least a good 5-6 SOT..

Some people say that it is a common bug in Android 5.0. Can anyone confirm?

The known bug with wifi is not battery drain but the difficulty to connect, to link the network.
