If your iPhone stops charging at 80%, you may be puzzled by this behavior. This tutorial will explain why this happens and how to address it. Understanding Apple's battery management features can help you optimize your charging routine and extend your device's lifespan.

Step 1: Understand Optimized Battery Charging

• What It Is: Optimized Battery Charging is a feature designed to prevent battery aging by learning your charging habits.
• How It Works:
  • It allows your iPhone to charge up to 80% and then holds off on charging to 100% until you need it.
  • This feature is most beneficial if you regularly charge your iPhone overnight or during extended periods when it's connected to power.

Practical Advice

• Check Your Settings: To see if this feature is enabled, go to:
  • Settings > Battery > Battery Health > Optimized Battery Charging.
• Turn It Off (If Needed): If you prefer to charge your iPhone to 100% every time, you can disable this feature.

Step 2: Examine Your Charging Equipment

• Check Your Cable and Adapter: Sometimes, the issue may lie with your charging accessories.
  • Inspect the lightning cable for any frays or damage.
  • Ensure that the power adapter is functioning properly and is compatible with your device.

Practical Advice

• Use Original Accessories: Always use Apple-certified cables and chargers to avoid potential issues.
• Try Different Outlets: Test charging from various power sources, as some outlets may have inconsistent power supply.

Step 3: Software Updates

• Keep Your iPhone Updated: Software issues can sometimes cause charging problems.
• How to Update:
  • Go to Settings > General > Software Update.
  • If an update is available, follow the prompts to install it.

Practical Advice

• Backup Your Data: Before performing major updates, ensure your data is backed up to avoid loss.
