Did you get a new battery or a new phone?To each his own, it's my money. The whole process at the Apple store took about an hour, very quick. After only 27 cycles and 1 month of use the battery was down to 3034 mAh (design max charge is 3076 mAh). The new one is 3140 mAh. How much difference does ~100 mAh make, who knows. But the old one just felt off to me.
