Battery life on 4.1 is terrable

[theantony]

Hi I just updated from 3.1.3 to 4.1 On my 3GS and my batter life now is terrible. After some reading there is suggestions about wifi or should I go to a Higher iOS.

It makes sense as IOS gets higher, more features and draws more current and thus uses more power.

Do PUSH notifications work?

To test, iPusher via App Store. Allow push with app.
If desired Settings / Notifications = OFF will completely disable PUSH.
