Since the Jelly Bean update, about once a day all of a sudden my battery meter goes to red with a ? (question mark) in it and then it shuts down. When I power my Bionic back up, the battery meter is still like that. I've installed battery app, since this started just to see what charge I have left and the battery is fine, at least 50-80% depending on what time of day. Later in the day = less battery left. If I then manually power down and back up, the battery level is correct. I just tried clearing the cache and will update this post with a photo if it happens again. Has anyone else had this issue yet?
