Hello

I was so happy with this device's endurance when I first got it. I could almost stretch it to 2 days with 3 hours on screen time. But after the 4.4.3 update this is no longer the case

Here are my stats before the update:

As you can see in the first screenshot, average battery drain was 2.8%/h, a modest 4 hours on screen + 5.5 hours awake (listening to music) all this in 1d11h. App usage is at 41%. The second screenshot is even more awesome: 1.8%/h with 4h50m and 7 hours awake in 2d5h !!!! App usage at 34% (slightly lower).

Here's a recent screenshot after the update:

The problem: the system uses too much battery. I can confirm this because it drains like 2-3% doing nothing in an hour, whereas before 1% would drain in like 2 hours (on wifi). App usage way too high because of android kernel and other system services. I barely used the phone for 1h49m (on screen) + 2 hours of listening to music. I know the problem is with the top three in app usage because when I put it in deep sleep (using DS Battery saver) over night, it only drains 3-4% in 7-8 hours.

I tried disabling auto-sync - DIDN'T HELP, battery % was going down as before.
I also have disabled the following apps since i don't use them (the same ones I had before the update, so there should be no difference): Facebook, Fitbit, Google Play Music, Google+, Hangouts, Kid Mode, OneDrive, Skype, Twitter + some more.

I haven't installed anything recently that would impact the battery performance.

After my update i went into system recovery and wiped the system cache.
For me the device seems to have better battery life.
