Everyone’s universal complaint about smartphones? Battery life! It’s a sad but true fact that we have been conditioned to think that if a phone gets 8 hours of battery life, that is “good”. That is not good, it is crap. My worst battery life experience was the Samsung Charge, which I returned because of this. It was lucky to get 6 hours with minimal use. That is useless. You can read about that whole incident here if you so desire.
I, of course, have to mention the “it doesn’t have a user replaceable battery” lame ass excuse that everyone uses for every other phone. All I have to say to that is, if you have to carry around a pocket full of batteries in order to have a phone throughout the day, you are doing it wrong.
