How do I keep my battery 100%?

Maintain Your Battery

1. Use the original charger that came with your device. Other chargers may charge your phone more slowly or may not work at all.
2. Keep your device at a cool temperature. Try to prevent situations that could cause your phone to overheat, especially when the battery is fully charged.
3. Charge your phone according to its needs. This will help maximize the battery life of your Android device.
