Certainly! Let's address your concerns about using a third-party MagSafe battery and the 80% charging limit on your iPhone.

1. Understanding the 80% Charging Limit:

• System Behavior:
  • The 80% charging limit is a feature designed to prolong the battery's lifespan by reducing the amount of time the battery spends at full charge, which can be detrimental to its long-term health.
  • When you enable the 80% charging limit, your iPhone will stop charging at 80% and display "Charging stopped" in the battery settings.

2. Third-Party MagSafe Batteries:

• Incompatibility:
  • Third-party MagSafe batteries may not fully recognize or respect the 80% charging limit set by your iPhone. This is because they might not have the same level of hardware and software integration as genuine Apple MagSafe accessories.
• Behavior:
  • You mentioned that the battery interface shows "Last charged to 80%" but the battery continues to charge to 100%. This suggests that the third-party battery is not heeding the 80% limit set by the system.
• Normal Situation:
  • This is indeed a known issue and can be considered normal when using third-party accessories. The system might not have the necessary protocols to enforce the 80% limit with non-Apple products.

3. Potential Risks:

• Battery Health:
  • Overcharging: Overcharging can potentially reduce the battery's lifespan over time. However, modern batteries and charging systems have safety mechanisms to prevent overcharging.
  • Heat Management: Continuous charging can generate heat, which is another factor that can affect battery health. Ensure that your device is well-ventilated and not exposed to excessive heat.
• Safety:
  • Use reputable third-party accessories to minimize the risk of safety issues such as overheating or battery damage.

4. Recommendations:

• Use Genuine Accessories:
  • For the best performance and safety, it is recommended to use genuine Apple MagSafe accessories. They are designed to work seamlessly with your iPhone and respect the 80% charging limit.
• Monitor Battery Health:
  • Regularly check your battery health through the Battery settings to ensure it is performing well.
• Alternative Solutions:
  • If you are concerned about battery health but prefer to use a third-party MagSafe battery, consider manually unplugging your device when it reaches 80% to 90% to mimic the 80% limit.

5. Conclusion:

• While using third-party MagSafe batteries can be convenient and cost-effective, they may not support all the features and protections that Apple's accessories offer. If you are concerned about battery health, using genuine Apple accessories is the safest and most reliable option.

I hope this helps clarify your concerns. If you have any more questions or need further assistance, feel free to ask!
