I Fixed my 4s battery woes after 5.01 with 2 steps 1. Disabled the Siri raise to speak 2. Unplugged my Microcell - I think this is the winner for me. I bought the at&t microcell after I could no longer disable 3G on the 4s like I did on my old 3GS and I thought the phone going in and out of 3g coverage constantly at my home was the cause of my battery leak. It seemed to help with the initial iOS 5 but when the update came out I knew things were not quite right still because I was only getting 3-4 hrs usage and charging every day. So I unplugged the Microcell and the phone sticks in 2G more now then before the update I think and I am getting my normal 6-7hrs usage and 2 days before needing a charge now. I'm going to re-enable raise to speak after I charge back up since I think the Microcell got it. Can anyone else with Microcells comment on how their battery usage are?
