I debloated my device

- Freezed all the samsung apps (Push, Cloud, sHealth etc)
- Changed Locating method to Wi-fi and network
- Change app theme to dark.
I can't run down the battery during a normal work day. I get home with around 40% left and that with 2 hours of streaming Spotify over bluetooth.
I've now upped my screen to max active brightness, as I just aren't using enough battery.
But I also use Adaway and Greenify (requires root) which also help battery.
