[Galaxy S 4 i9505 Original Android Development] FPSUsername:
I have the same issue. When the screen is off, it has some great batterylife, but when screen is on, it uses a lot of it. I was only swiping my screen a bit, open whatsapp, a littlebit of browsing and it dropped a lot within a small amount of time.

As you can see in the pictures, those drops are not from playing games, it was just screen on time. I use lux autobrightness and it is mostly around 20% brightness.

This is the stweaks profile I use:
