Just curious if anyone has actually tested all of the 3 modes to see which one actually has the longest battery. I have been running night time saver since I got my phone which turns off data after 15 mins of not using the phone between 10pm to 5am. When I look at what's using the most of my battery at that time its "phone idle" and the statement below it says if ur in a low radio signal area put your phone in airplane mode to save battery. So what I'm trying to get at is, is night time saver actually using more battery then its actually saving. Is having the phone in performance mode where it never turns off your data connection better? Am I thinking too much into this? Lol
