I replaced the battery of my BT headphone. Most electronic devices has a this type of battery - Lithium-ion. When your electronic device got its battery easily drain, it's because it gets swollen just like this one. Batteries like this use chemical reaction to generate power. When the battery has reached its limit, it will no longer charge completely, which results in creation of gas, leading to swollen battery. 📌 Never use your electronic device while charging. You don't just destroy it's battery, you also put your life in a dangerous situation.
