I think OP is worried about keeping their charged phone on the charger just for this feature. I also heard that keeping devices with batteries connected to a charger for a long time is not good because it generates a lot of small charging cycles pushing the battery to 100% repeatedly. I’m actually curious whether that’s true for the modern smartphones or not.
FWIW my Pixel has an “adaptive charging” feature that slowly charges the phone to 90% overnight and then tops it to 100% just before an alarm. It seems to be aimed at reducing this exact effect so I wouldn’t be surprised if there is something to it.
