Battery life has been reasonable for me since the day I got it. And that was the first day it was available. But just within the last 36 hours, the battery drains in a matter of 3- 4 hours, and when I put it on a charger, it takes forever to gain any charge. Plugged it in 2 hours ago and its only climbed from 9% to 24%. Thats way slower than normal. Bad battery? Its not that old.
