I'd say battery life. I moved to Android for this reason. I can get a phone with around ~4000mAh battery vs 1715mAh on the 6S or 2750mAh on iPhone6S+. Furthermore, my phone supports Qualcomm's Quick Charge tech which means plugging in the phone for a few minutes gives it a lot more charge. Between these two points; my phone very very rarely runs out of battery. When I was on iOS it'd be almost every day.
