Just got my new 6+ (iOS 8.1.2) and restored my 4S backup to it. (iOS 7.1.2) Under settings > Mobile > Call Time, the lifetime on my 6+ indicates a significantly different duration, 1hr vs 11 days, from the one on my 4S. I did a similar procedure back then on my 4 to 4S both on ios 7, and it tallied. Any idea why? Is it number dependent? My 6+ is currently using a different number from the 4S.
The same thing for mobile data usage counters.
