You askedDo Android or iOS users drain more battery?
iOS, by a little. The median iPhone user drains 1,538.5 mAh a day against 1,489 for Android, and the averages agree: 1,589.5 against 1,508.2. There are 146 iOS users and 554 on Android, so the Android figure rests on nearly four times as many people.
