I agree that quantitative metrics would make for a much stronger comparison than a few people's subjective experience using both kinds of devices.
In absence of that, even an anecdotal comparison seems more relevant than a statement that only considers one of the two items being compared.
Update: Because I was curious whether my subjective experience was backed by real numbers, I looked up the top few Android and iPhones with the greatest battery life as per the first website I found [1] and calculated their efficiency based on their battery capacity. Various iPhone 13 models used 3.1 to 3.6 mAh per minute whereas the Android phones used 4.0 mAh/min (Moto G9 Power), 4.2 mAh/min (Samsung Galaxy A03s, Realme 9 Pro), 4.3 mAh/min (Nokia G21).
