A:Answer Like any mobile device, the battery life depends on what you are doing on it. Gaming has a shorter life than Email. The more apps you have open the less time it will run on battery. That being said, my wife gets on average 13-14 hours from a full charge. She usually is just doing words with friends, Email, and texting. She is pretty good about closing apps when done with them. I don't think she's ever gotten the 16 hours advertised, but I'm betting that's for having it turned on with nothing running.
