Needing to have that much off just to get 9-11 hours is some bull. Sounds like what you're saying is you basically just turn it into an iPhone 4.
How come? I don't need apps refreshing in the background and I select a few apps to have access to location services. All the system features in location services do nothing of benefit to me so I switch them off. I don't like parallax and I don't like the app opening & closing animations, so how am I in any way creating an iPhone 4 by doing all this?
