The Overnight Charging Habit That's Aging Your Phone Battery Faster Than It Should

Leaving a phone plugged in overnight usually won’t cause immediate damage, but it can speed up long-term battery wear.

The main issue is prolonged time near 100% charge, which creates voltage stress and can age lithium-ion batteries faster.

Heat makes the problem worse, especially if you use the phone while charging or use uncertified accessories.

Apple and Android makers include optimized charging and battery protection features to reduce wear.
