In my limited experince my iPhone 4 lasts up to twice as long as some phones of my friends. And iOS 5 sounds like it has many features you may want (notifications, wifi sync, Sync with iCloud). But speaking of todays sync: It is in the summary Tab when the iPhone is connected. No learning how to disable it, it is just there where you would guess it is.
