Hi, I have always left wi-fi and location services switched on with my IP4 and find that I get very good battery life. I have always had email push and notifications switched off. Anyway recently I needed to switch notifications on (still have email push off though) and have been surprised to find that my battery life hardly seems any worse, if at all? I seem to remember something about Apple changing the way notifications were handled a little while back, and wonder if this had a positive impact on the battery? Can anyone enlighten me on all things notifications related?
