I still remember reaching into my backpack to retrieve my Macbook in sleep mode only to find it hot to the touch, having woken up for some goddamn stupid reason. We had "proper" sleep decades ago: we called it "hibernate". Modern "smart sleep" is a technological regression, and Apple is as big an offender as any.
I leave my phone off for most of the day, and 100% of the time that it's on it's in battery saver mode. In any case, it's an irrelevant comparison, because a phone's thermals have nothing in common with a laptop's thermals.
