To properly charge a smartphone and extend its battery life, consider the following tips:
1. **Avoid overcharging**: Lithium-ion batteries don't like being overcharged, which can lead to a fire. However, modern smartphones have built-in protection against this.
2. **Keep your phone at room temperature**: Extreme temperatures can damage the battery.
3. **Avoid deep discharging**: Try to charge your phone when the battery level is around 10-20%. Deep discharging can reduce battery capacity.
4. **Don't overheat your phone**: High temperatures can cause battery degradation.
5. **Avoid fast charging**: While convenient, fast charging can heat up the battery and reduce its lifespan.
6. **Keep your battery charged between 10-90%**: Avoiding full charges and discharges can help extend battery life.
7. **Don't use your phone while charging**: This can cause overheating and reduce battery life.
8. **Calibrate your battery**: Every 6 months, discharge your phone to 0% and then charge it to 100%.
9. **Store your phone properly**: When not in use, store your phone with a 40-60% charge and in a cool, dry place.
When buying a new smartphone, follow these steps to help the battery reach its maximum capacity:
1. Charge the phone to 100% without using it.
2. Let the phone discharge to 0% without interrupting the process.
3. Repeat this process 2-3 times to help the battery reach its maximum capacity.
By following these tips, you can help extend the life of your smartphone's battery.
Here are the key facts extracted from the text:
1. Modern smartphones use lithium-ion and lithium-polymer batteries.
