Basically turned off or disabled allot of stuff in my S5 and I'm now able to get 48-50hrs on one charge..

Things I did..
- Set screen to auto adjust
- Set all transitions effects to 0.05x
- Turn off all Vibration

- Turn off haptic feedback
- Disable SVoice home button
- Turn off all gestures and smart stay
- Turn off 'Ok Google'
- Mainly Black Wallpaper
