How to turn on Low Power Mode on an iPhone
In short
Open Settings, tap Battery, then Power Mode, and switch on Low Power Mode. On iPhone 14 and earlier the switch is directly on the Battery page. The battery icon turns yellow, and the mode switches off by itself when the phone is charged to 80%.
Low Power Mode makes a charge last noticeably longer by reducing background activity, mail fetching, some visual effects and screen brightness. Use it whenever you will be away from a charger for a long time. The pictures are our own, from an iPhone 14 Pro and an iPhone 17e, both on iOS 27.0.1 in dark mode.
4 of 4 steps show a real screenshot from our iPhone 14 Pro (iOS 27.0.1) and iPhone 17e (iOS 27.0.1).
What changed: new screenshots from our iPhone 17e on iOS 27.0.1, dark mode, and the wording checked against those screens.
Steps
- 1
Open Settings and tap Battery
Battery has a green icon in the main list.
- 2
Tap Power Mode and switch on Low Power Mode
On iPhone 14 and earlier, the Low Power Mode switch is on the Battery page itself. On our iPhone 17e the Power Mode page also has Adaptive Power and Adaptive Power Notifications above it.
- 3
Check the battery symbol
With Low Power Mode on, the battery symbol in the status bar turns yellow. On our iPhone 17e it was yellow on the Home Screen, at the top right. We switched Low Power Mode off again afterwards.

Add it to Control Centre
Open Control Centre, touch and hold an empty area, tap Add a Control and type Low Power in the search field. On ours, Low Power Mode was listed under Utilities. Tap it to add it. After that it is one tap away.
If you do not see this option
- There is no Power Mode row. Apple says Power Mode is on iPhone 15 and later. On iPhone 14 and earlier the Low Power Mode switch is directly on the Battery page. Source: Use Low Power Mode to save battery life on your iPhone
If this does not work
- Low Power Mode turned itself off. Apple says it turns off when the iPhone is charged to 80% or higher.
- Low Power Mode turns on by itself below 20%. Apple says that happens when the iPhone supports Adaptive Power and Adaptive Power is on.
- New emails only arrive when you open Mail? Apple lists email fetch among the things Low Power Mode turns off, along with automatic downloads and Background App Refresh. Open Mail to check for new messages, or turn the mode off.
- The screen looks dimmer than usual? That is expected: Apple says Low Power Mode reduces display brightness and turns off some visual effects.
Good to know
The iPhone offers Low Power Mode by itself at 20% and again at 10%.
While it is on, the screen locks after 30 seconds, 5G is limited on some models, and iCloud Photos pauses syncing.
To turn it on automatically, open the Shortcuts app, tap Automation, choose Battery Level and add the action Set Low Power Mode.

iOS 27 compared with iOS 26: On our iPhone 14 Pro, the Low Power Mode switch is at the bottom of the Battery page on both iOS 26.7.1 and iOS 27.0.1. On our iPhone 17e with iOS 27 it is on the Power Mode page.
Version history: the iOS 26 version of this guide, with its own screenshots.
