So I've had the RAZR maxx since it came out and never had a problem with the battery life. It's way better than my incredible ever was. Recently though I've been having serious issues. It started about two weeks ago. The phone won't charge past 80%, sometimes it'll get to 90% but will quickly drop. It shows charging on the screen and even after a full night it won't fully charge. I really don't know what to do so any help would be greatly appreciated.
