Ever since I downloaded iOS 8 I've never seen my signal strength go over 3 dots. It rests between 2-3 dots mostly 3. I open the new battery usage garage and it says my low signal is causing a good portion of my battery usage. I live in a very large city with as far as I know great LTE coverage (Jacksonville, Florida) and travel to St. Louis a lot. This phone was just replaced about 1.5 weeks ago. Does anyone else have issues with poor reception causing you battery to drain?
