Save battery life with Power Modes on iPhone

iPhone offers power-saving features that help extend battery life based on your needs. Use Adaptive Power to let iPhone automatically adjust performance based on your usage patterns, or turn on Low Power Mode to manually reduce power consumption when your battery gets low.

Turn on Adaptive Power

On iPhone 15 Pro or later, Adaptive Power helps extend the battery life of your iPhone on days when your usage is higher than usual. When turned on, Adaptive Power works automatically in the background so you don’t need to manage it. It uses on-device intelligence to predict when you’ll need extra battery power based on your recent usage patterns, then makes performance adjustments to help your battery last longer.

Note: On iPhone 17, iPhone 17 Pro, iPhone 17 Pro Max, and iPhone Air, Adaptive Power is on by default.

When enabled, Adaptive Power can lower screen brightness, limit background activity, and make performance adjustments to conserve power throughout the day. It can also automatically turn on Low Power Mode when your battery reaches 20%.

  1. Go to the Settings app  on your iPhone.

  2. Tap Battery, tap Power Mode, then turn Adaptive Power on or off.

You can get notifications when Adaptive Power turns on during the day: Go to the Settings app, tap Battery, tap Power Mode, then turn Adaptive Power Notifications on or off. If you turn off notifications, Adaptive Power continues to help extend your battery life.

Manage Low Power Mode

Low Power Mode reduces the amount of power that your iPhone uses when the battery gets low. It optimizes performance for essential tasks like making and receiving calls, sending and receiving email and messages, accessing the internet, and more. On iPhone models with ProMotion display technology, Low Power Mode limits the display refresh rate to 60 frames per second.

Note: iPhone might perform some tasks more slowly when in Low Power Mode.

To turn Low Power Mode on or off, do any of the following:

  • iPhone 14 or earlier: Go to the Settings app , then tap Battery. Tap Low Power Mode.

  • iPhone 15 or later: Go to the Settings app , then tap Battery. Tap Power Mode, then tap Low Power Mode.

  • In Control Center: Add the Low Power Mode button to Control Center, then tap the Low Power Mode button.

Low Power Mode automatically turns off when iPhone charges to 80% or higher.
