So I got the 4.4 update a few days ago, and I immediately noticed that Android System was using more power than usual. I was told to let it settle, but it didn't change. It used to be around 5% on a normal day, but now it's around 40%. I used to get a good 17 hours out of my phone with 4.3, but now it's done at around 14 hours, which is worse than 4.2!
Here's a link; maybe the problem is with KitKat? http://forums.androidcentral.com/and...n-4-4-2-a.html
I took some screenshots, hopefully you can see something wrong with my phone.
