Seriously? I would assume you're talking about the "hidden" System Services settings that people have come to find drains the battery when they're on? If so, please tell me which of these things you need on a daily basis and how they make your "smart" phone any less "smart" when they're off???
I have one thing under System Services turned on...Cell Network Search. Now, please explain how Compass Calibration being off is making you lose sleep? Because your phone doesn't know magnetic north from north??? WTF? Who cares? Unless you're planning on going on an expedition, why do you need that? When you're using Maps for directions, do you think it NEEDS to know magnetic north??? No. It's just gonna give you directions and you'll get there just the same.
Same goes for Diagnostics & Usage. It's not doing anything other than sending info back to Apple. Plenty of people will leave this on and they'll get the info they need. Turn it off! It won't make your phone any dumber.
Location-Based iAds...do you really care if you get ads in apps that are tailored to where you are? Good grief...if I could get no ads at all, I'd be all for that!
Setting Time Zone...I rarely travel outside my timezone, so this is a non-starter for me. This is the one I can see being useful to someone that travels a lot. If you don't? TURN IT OFF!
And Traffic. If I'm worried about getting good traffic in a maps app, I'm going to use another, better app than the stock Maps app. So...again...turn it off.
Jeez. Some people just can't live unless they're complaining.
