People have to start looking at today's smartphones as "pocket laptops". I've been saying this for a while. Battery size and capacity go hand in hand. You can't have a thin, light mini-computer and expect it to last for days on one charge like the old phones. There are many options to be sure you don't run out of power. Powerskin, seperate power pack, extra chargers for wherever you spend your time, extra batteries. There's not really any other way around it if you really use it a lot.

Battery life threads have been done to death. We all know the battery life is what it is. It will work for a real days worth of use for the average business user but for the kids playing games and watching movies well then it will only last a few hours.

Best advice is keep a charger handy
