My battery was normal up until 11 am today. I was around 50%, and within the next 30-40 minutes the battery dropped down all the way to 30%. It has been draining steadily since then. I wasn't using it more than normal, and I didn't install any new apps this morning. The app that was using most of the battery was facebook which is really strange because it is never that high on the list for battery usage. I forced closed the facebook app but that didn't seem to help. I updated a couple of apps yesterday afternoon, but the battery was fine until 11 am this morning. I shut the phone off for a while, but I turned it back on. Right now am at 9% battery. Uptime is 12:30 mins, awake time 06:20 mins after turning the phone back on. Anybody have an suggestions on what the problem could be?
