Yeah, I use it non stop at work duirng my 12 hour shifts. I always have my screen display settings on MAXIMUM and I watch a ton of videos and that zaps the battery so much quicker... the screen never goes off or even dims... I find I have roughly 3 hours of power using on each battery... maybe I should take bluetooth & wifi off while I am watching videos but I usually don't worry about that because I also have an emergency charger with me. All this fits inside my kickazz case and weighs under 1 pound though.
