I turned push email to fetch every 30 mins. I turned off all system service location services except cell towers. Then I did a hard reset. Today after 13 hours being off the charger I'm still at 63%. Last night my phone was dead right at 12 hours. I've also noticed, my phone has not been hot at all today. One other curious thought. Yesterday, Siri was not connecting to the server. I asked this forum if anyone else was having this issue (nobody was). Also, my phone was very warm. I turned Siri off and then back on, and then it started working normally. I'm not sure if these are related or not, I'm just glad my battery has returned to my previous uP4 levels. This phenomenon is real, so I feel everyone pain that is experiencing this issue.
