Own: iPhone 4S w/AT&T I'm having an issue with my phone that involves the battery, but I don't believe it is related to the current one everyone is raving about. While I'm in my office my phone loses 7%-10% battery life an hour or so while not in use. The issue I'm having is one I not only share, but a fellow co-worker in my office who has an iPhone 4 (not a 4S) and has AT&T. I have noticed that my phone is always going from 3G, to E, to "Searching" and finally to "No Service" -- it doesn't necessarily have to be in this order and a minute or so after I walk out of my office my phone goes back to 3G from "Searching" or "No Service" . Basically the phone is always changing from one of those and I've concluded that this is killing my battery life and my co-worker notices the same with his phone. While I'm at home (and he agrees) the phone can stay at the higher 90% range for a over 5 hours when not in use. One last note: I have a co-worker who uses an iPhone 4 on Verizon's network and has much better battery (as well as overall service) in our office and doesn't have any issues. Now my questions is, what can I do about it aside from turning off my cellular data and will this even help me?
