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.2752 mAH, specs say 2750. So the plus is about the same.
