Well you can take the battery size (and screen times you get from those). iPhone batteries are tiny compared to android. Like seriously tiny that my 10Wh Powerbank can charge it 5 times with some to spare (I only really get 4 due to losses but still). So yes comparing iPhones to anything else highly suggests that the tuning Apple did pays off. That being said: I’m not aware of a useful comparison. I’m not even sure how you would design something like that, ie what would you like to keep constant?
