Using Settings

1. Open Settings:

   • Open the Settings app on your iPhone.

2. Go to Battery Settings:

   • Scroll down and tap on Battery.

3. Battery Health:

   • Tap on Battery Health. You will see two important pieces of information:
     • Maximum Capacity: This indicates the maximum battery capacity relative to when it was new. A lower percentage indicates that the battery has degraded over time.
     • Peak Performance Capability: This section will tell you if your device supports normal peak performance. If your battery has degraded significantly, you might see a message indicating that your battery’s health is significantly degraded and needs to be serviced.

Using Battery Usage Information

1. Battery Usage Details:
   • In the Battery settings, you can also view detailed battery usage information by tapping on Battery Usage. This shows you how much battery power each app has consumed over the last 24 hours or the last 10 days. It can help you identify apps that are consuming a lot of power and might be contributing to battery drain.

Additional Tips

• Battery Replacement:

  • If your iPhone’s battery health is significantly degraded (typically below 80% maximum capacity) and you’re experiencing poor battery life or performance issues, you might consider getting the battery replaced. Apple offers battery replacement services for eligible devices.

• Battery Recalibration (iOS 14.5 and later):

  • Starting with iOS 14.5, Apple introduced a recalibration process for iPhone 11 series and iPhone 12 series models to improve battery health reporting accuracy. If you notice unexpected battery behavior or significant battery health degradation, you might benefit from recalibrating your battery. This process typically occurs over a few weeks of regular usage after updating to iOS 14.5 or later.

• Battery Saver Mode:

  • If your battery health is not optimal and you need to conserve battery life, you can enable Low Power Mode. This mode reduces device performance and limits background activity to extend battery life.

By checking your iPhone’s battery health regularly and taking appropriate actions, such as replacing the battery if necessary, you can ensure optimal performance and battery life for your device.
