I get this problem, too. And it seems like a common Android 4.2.2 problem. The Android OS on 4.2.2 using battery like 10 times it did on my S3, 4.1.2

Do you have Wi-Fi enabled? Apparently this is a well-known problem on certain networks with lots of broadcast/multicast packets (like DropBox LAN sync discovery). I've been trying to figure out a way to filter those out, like this: https://code.google.com/p/android/is...etail?id=56471

About these:
ril-fd , l2_hsic, radio interface, umts_ipc0

ril.fd & umts_ipc0: Wlan advanced konfiguration: Keep Wlan on during sleep - off & open Data Usage, press Menu-button: Restrict background data
radio interface: Do you use the radio? If you don't get Link to SD and freeze the app.
l2_hsic:

+1, no deep sleep state.

I have kk since published, but this issue only since a pair of weeks ago without any flashing or app installing... Tried releasing my stock TTT fw and last India fw without wipe data, nothing... Last thing i left to try is wipe data, format every thing and refreshing fw when i get some time...
