Apple Watch Low Power Mode extends battery life by turning off selected background health measurements and alerts, disabling Always On and certain gestures, and reducing or slowing some background activity. Its connectivity effects depend on whether your paired iPhone is nearby. Workouts can still measure heart rate and pace in ordinary Low Power Mode, while an optional reduced-reading setting trades workout detail for additional savings on supported watches.
What Apple Watch Low Power Mode turns off
Apple lists these features as turned off while Low Power Mode is active. Availability can vary by watch model and software version.
| Feature | What changes |
|---|---|
| Background heart-rate measurements | Background readings stop, including during sleep. Workout readings can still be available. |
| Background blood oxygen measurements | Background readings stop, including during sleep. |
| Heart data for hypertension notifications | The watch stops collecting heart data for this feature while the mode is on. |
| Heart-rate notifications | Irregular-rhythm, high-heart-rate, and low-heart-rate notifications are turned off. |
| Always On display | The display no longer stays visible with your wrist down. Raise your wrist or tap the screen to wake it. |
| Double Tap and Wrist Flick | These gestures are disabled while Low Power Mode is active. |
| Workout-start reminders | The watch stops reminding you to start a workout when it detects activity; you can still start one manually. |
| Time in Daylight | The feature is turned off while Low Power Mode is active. |
These are specific reductions, not a complete shutdown of health or workout tracking. Apple’s Low Power Mode guidance lists the affected features.
Features that become less frequent or slower
Some functions continue with reduced frequency or speed:
#1 Best Overall
- Durable, woven cable with fast-charging capabilities for select Apple Watch models. Simply hold the connector near the back of the watch, where magnets cause it to snap into place automatically.
- Supports fast charging on Apple Watch Series 7 and later and Apple Watch Ultra models. Supports regular charge times on all other models.

- Animations and scrolling may appear less smooth.
When your iPhone is not nearby
When Low Power Mode is on and the paired iPhone is not nearby, Apple says Wi-Fi and mobile-data connections, incoming calls, and notifications are turned off. Missed calls and notifications are retrieved about once an hour. If you open an app that needs data, Wi-Fi or mobile data can turn on temporarily; Apple warns this can use significant battery.
Other notifications may be delayed, and Apple’s watchOS 26 guide warns that emergency alerts may not arrive. Do not rely on the watch for timely communication in these conditions. See Apple’s watchOS 26 battery guidance.
What still works in Low Power Mode
You can still view the display by raising your wrist or tapping it, open apps manually, and use core watch functions, subject to reduced background updates and possible delays. You can also start a workout manually.

Low Power Mode during workouts
Ordinary Low Power Mode and Fewer GPS and Heart Rate Readings are different settings. The second option makes more substantial tradeoffs in workout data.
Ordinary Low Power Mode
In ordinary Low Power Mode, the Workout app can still measure heart rate and pace. You can have Low Power Mode turn on automatically when a workout starts:

Fewer GPS and Heart Rate Readings
This separate option reduces GPS and heart-rate readings during supported outdoor walking, running, or hiking workouts. Apple says it turns off workout alerts, does not record splits and segments, and makes some metrics, including current pace, unavailable. It activates when Low Power Mode is on and a supported outdoor workout begins in the Workout app.

These details are in Apple’s Low Power Mode support article.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Is Apple Watch Low Power Mode safe to use?
The key tradeoff is reduced or delayed information: background heart-rate and blood-oxygen readings and several heart-related notifications are turned off. If you depend on those features, account for the monitoring gap while Low Power Mode is active. When the iPhone is away, calls and notifications are also restricted, and emergency alerts may not arrive.

When a more selective battery fix may help
If you want to reduce power use without turning on all of Low Power Mode’s restrictions, Apple suggests checking battery health and investigating causes of unusually fast drain. Its guide, If the battery in your Apple Watch drains too quickly, covers troubleshooting. Apple also explains how to check your battery and charge your Apple Watch.
