iFixit's teardowns revealed the battery capacity for iPhone 6S to be 1715 mAh and 2750 mAh for the 6S Plus. My 6S shows 1740 mAh in the coconutBattery app. What does yours show?
Whoa, click on device details...my iPhone was built 12 days ago.
That boggles my mind. Tim Cook is a mastermind of logistics.
Also, I'm wondering if the 6s doesn't do 2.1A charging...System Profiler says 500mA requested, 500mA extra operating current...that's 1A. The iPhone 6 would say 500mA requested, 1600mA extra operating current.
