TWO Android systems draining battery??

[JohnnyGui]

Good day to you all,

Recently after a small Android update (still having version 4.4.2) I noticed the battery was draining faster than it used to. Before that, it was consuming roughly 1% per hour in idle. This has changed now to 3-5% per hour. Looking at the battery info I noticed the Android system was the biggest batterysucker here. Not only that, there are even TWO Android systems shown and I began to think there's something wrong here



Also looking at the wakelocks shows that my phone is barely able to get into sleepmode.



Before posting this thread I have literally tried every option to see if it could lessen the battery consumption:
- Disabled Google location reporting services
- Disabled GPS
- Disabled Google sync
- Disable Wifi when in Sleep mode
- I don't use Google Now so it's disabled
- Widen the Facebook refresh intervals to 4 hours
- Wiped the cache partition

None of the above worked and I started to think that the second Android system here might be the cause.

Should there be a second Android system consuming battery? What could be the problem here??
