AP PSYCHOLOGY

Detailed explanation-1: -If you leave your phone on the power adapter for long enough, the battery will drain a little bit to 99 percent instead of 100 percent. Then, the charger will kick in to take your phone back up to 100 percent before it shuts off again.

Detailed explanation-2: -Android phone manufacturers, including Samsung, say the same. “Do not leave your phone connected to the charger for long periods of time or overnight.” Huawei says, “Keeping your battery level as close to the middle (30% to 70%) as possible can effectively prolong the battery life."

Detailed explanation-3: -Batteries decay from the moment you start using your new phone. This means they gradually lose their ability to hold a charge. By charging your phone overnight, you’re increasing the amount of time it spends with the charger. As a result, it degrades the capacity much sooner.

Detailed explanation-4: -The most common myth about overnight charging is that it can overload your battery. This is simply not true. All smartphones are designed with protective measures that prevent the battery from overcharging once it’s full. As soon as the battery reaches 100%, it stops charging.
