After seeing the battery life I'm getting with my new SGS5 (almost 6 hours of on screen time) I'm happy I decided to go with this one instead of the new X.
I waited months for it only to be disappointed with the battery. No way it can even get close to the SGS5 (or any other flagship for that matter).
I'm sorry that you need to have your screen on for 6 hours of your day.
Whether it's for work or just your gadget addiction, you really should try seeing the real world. It's not as bad as it seems...
