Yeah no doubt more is always better, but again no movies are 4 hours or longer. Most will not be watching back to back without having a charger with them. It also is to be seen if we can interchange these batteries. Since the rear plate does come off.
I'm quite impressed with my battery life. I was at 30% last night and that was 34 hours since my first charge. Now granted 16 hours of that time it was just sitting there but, that's pretty good to me. This was mainly web browsing, you tube, and installing some apps.
