Does apple or android use more battery?
No idea but I'd guess apple judging by everyone I know who has one is constantly changing them
Depends on the battery capacity and how often you use a phone. My LG G4 can last up to 2 days with minimal use whilst other times I can drain the battery within 10 - 12 hours thanks to intensive use (usually bluetooth is notoriously hungry).
Overall I doubt there's much difference.
Which iPhone -
Which android phone?
generally speaking, androids are better than iphones when it comes to battery capacity and battery charging rate..
however, it does depend which phones we are comparing.. as all phones are optimised differently, hence deplete battery charge at different rates depending on the task the phone's carrying out
The less you use it the longer it lasts IMHO
