iOS 4.1 WiFi killing battery
Since getting the 4.1 update I noticed the battery life on my iPhone 4 is no where near what it was before that. For awhile I thought maybe it was an app or something. I even disabled push notifications for a little while and it didn't help. Then I turned off push gmail and location services, no change again. Then starting this Monday I turned off Wifi all the time and never used it. The battery life was better but not that great because of 3G being used.
Then I turned wifi back on last night. So far today I have 18 hours of standby and 2 hours 10 minutes of usage and my battery is at 66% already. This is extremely poor IMO compared to what I was getting. All this usage was at home on wifi and not 3G.
Has anyone else noticed this? Should I see if 4.2 improves it or take it in to Apple? I saw someone say that 4.2GM had really improved their battery life so I'm hoping this is something with 4.1 and not my battery.
