One of the most important ways you can conserve your battery is to avoid overcharging. Keeping battery-operated devices plugged in after they have reached full charge may reduce battery life over time. Exposing batteries or devices to extreme temperatures can also shorten expected battery life. When batteries become hot they drain faster, so whenever possible store them in a cool place. Other great tips to extend battery life for devices like your smartphone and tablet include closing out apps when you’re finished using them, turning off your notifications or try switching to airplane mode to save your battery whenever you find yourself in an area with little or no reception.
