How to Care for Your Device Battery
Battery behavior depends on the device, battery chemistry, charging system, and manufacturer settings. Follow the instructions for your device and use these general precautions:
- Avoid overheating. Keep the device away from direct sunlight and other heat sources, especially while charging.
- Use a compatible charger and cable that meet the device manufacturer’s requirements.
- Enable optimized charging or battery protection features when they are available in the operating system.
- Before storing a device for a long time, follow the manufacturer’s recommendations and do not leave the battery completely discharged.
- Install system updates and reduce unnecessary power consumption when you need longer battery life.
- Check battery health in the operating system settings. If the battery swells, overheats, or causes unexpected shutdowns, stop using the device and contact a qualified service provider.
