Im having a serious issue on with my 4s. I have a Verizon 4s and I'm currently in a hotel for work. The signal in here is very faint and often no 3G. I'm using wifi for data but something is causing a serious battery drain. My phone is dropping a percent per min and gets warm. I have tried reboots, killing apps, resetting the network and nothing helps. This issue started today and I came here last night but did not notice anything yesterday. I'm not sure what to do at this point and maybe it needs to be swapped out.
