Follow these tips to reduce power consumption and extend the battery life of your iPhone, especially on older models.

  1. Turn off Screen Mirroring on Mac
  • If you don’t use iPhone Screen Mirroring on Mac (a new feature in iOS 18), turn it off:

Settings → AirPlay & Continuity → Screen Mirroring → Off.

This will help reduce battery consumption, especially if your computer is running Windows or Linux.

  1. Manage Apple Intelligence features
  • Some new iOS 18 features, such as emoji generation, consume a lot of power.

If you rarely use them, simply turn them off to avoid unnecessary strain on your battery.

  1. Turn off fitness tracking
  • Step counting and other health data also drain your battery. If you don’t use this feature:

Settings → Privacy & Security → Motion & Fitness → Turn off Fitness Tracking.

  1. Turn off unnecessary notifications
  • Constant notifications drain battery power not only when you receive messages, but also when the screen turns on.

Go through the list of apps:

Settings → Notifications → Select apps → Turn off notifications for unnecessary apps.

  1. Use Dark Mode (OLED displays)
  • Devices with OLED displays (iPhone X, XS, 12 and later, except XR, 11, SE 2 and 3):

Dark Mode saves battery power by using less power on black and gray shades.

Settings → Display & Brightness → Dark Mode.

  1. Additional tips:
  • Turn off location services for unnecessary apps.

Settings → Privacy & Security → Location Services → Turn off for unnecessary apps.

  • Close resource-intensive background processes.

Settings → General → Background Content Refresh → Turn off for unnecessary apps.

  • Use Low Power Mode.

Activate it when the battery is low:

Settings → Battery → Low Power Mode → Turn on.

Following these recommendations, you can significantly extend the battery life of your iPhone, especially if you use iOS 18 features selectively.
