Battery safety: Lithium-ion batteries
Overcharging can cause your battery to overheat, which can lead to fires or explosions. Charge your device at room temperature where you can see it. Soft surfaces, like a couch or bed, can trap heat around the battery and cause the device to overheat. Charge your battery before it drops below 30% to help it last longer and work safely.
