Replace your battery if it’s damaged or no longer holds a proper charge. Just like cars, phones are meant to flex during an accident, so even a glued-in battery can bump into nearby components when dropped, resulting in a puncture. And most importantly, dropping your phone hurts your battery, too, not just your screen. High temperatures can also reduce battery efficiency, so try not to leave your phone in the car on a hot day. Leaving your battery 100% charged or completely empty for a long period of time can also shorten your battery’s lifespan, so if you plan on storing your device without using it for a few weeks or more, charge/discharge it to about 40% and turn it off beforehand. Avoid using low quality or damaged charging cables or adapters as they risk uncontrolled, uneven, or excessive power management that can cause damage or even result in fire.
