Charging Overnight: Why You've Been Doing It Wrong

What happens when your phone reaches 100% but stays plugged in all night? Does the charger keep pushing electricity into a full battery, or does charging actually stop? In this video, we explore what really happens inside your phone once the battery reaches 100%. You'll see how the charging system and battery management system control power, why charging slows near full capacity, what “100%” actually means, and why some phones intentionally stop charging around 80%. We’ll also look at overnight charging, lithium-ion battery aging, heat, optimized charging, and whether you really need to follow the famous 20–80% battery rule. The surprising part is that the charger isn’t really the one making the decisions — your phone is. The adapter provides power, while the phone decides how much the battery is allowed to receive.
