After doing the latest update, my battery drains only after about an hour of use. Sometimes, it just shut off with well over 50% battery life left. Most of my text messages have to be resent numerous times. I also am experiencing a loss of 4G network in areas where I've always had it. There have been times where I completely lose service all together and won't regain it until several minutes later.
Am I the only one experiencing these issues?
