I have an iPhone 4. Under Settings > General > Usage, there is a button to "Reset Statistics". After reading the manual, I'm not clear on one point: if I reset the statistics, will the entry under "Call Time: Lifetime" also be reset?


After a quick test, everything but "Call Time: Lifetime" and the statistics under "Time since last full charge" was reset.

It only makes sense that the field "Call Time: Lifetime" doesn't get reset since it shows the the total physical time the phone was being used to call. If it was restored and set up as a new phone I believe that the setting will then be reset since it will be technically a new life for the phone. Unless AT&T/Verizon keeps track of that data through your number. Then you would change your number to reset that field. Though I wouldn't be trying that anytime soon.


I would not recommend reseting your statistics on a iPhone 4S for mine knocked out everything on my phone and I ha to go to AT&T to get it reset again to get my phone back. Everything was deleted.


It clears all of your revived and sent data for calls and it will not hurt your apps

    This doesn't particularly answer the question - the OP wants to know if the Call Time: Lifetime is reset when you reset the call statistics. Thanks! – Faiz Saleem Mar 17 '13 at 22:02
