How to Extend Apple Watch Ultra Battery Life on Long Hikes

For a long hike tracked as an outdoor workout, turn on Low Power Mode and enable Fewer GPS and Heart Rate Readings in Workout settings. This is Apple’s most directly relevant battery-saving combination for hiking, but it reduces workout data and disables some features, so choose it before setting out.

Set up the watch for a lower-power hiking workout

  1. Check the charge before departure. Start the hike with as much battery as your route requires; there is no guaranteed runtime for a particular hike.
  2. Turn on Low Power Mode. On the watch, open Control Centre or Settings and enable Low Power Mode. Apple documents that this mode changes some watch functions, including Always On display and background heart-rate measurements. Some connectivity and notifications are limited when the iPhone is not nearby. Apple’s Low Power Mode guide explains the changes.
  3. Enable reduced workout readings. On the watch, open Settings > Workout and turn on Fewer GPS and Heart Rate Readings.
  4. Start an outdoor workout in Workout. The reduced GPS and heart-rate reading setting takes effect only while Low Power Mode is active and a supported outdoor walking, running, or hiking workout has been started in the Workout app. Apple says reducing reading frequency can extend battery use significantly during long workouts, but does not give a guaranteed number of additional hours. Apple Support: Use Low Power Mode on your Apple Watch.

Choose between standard tracking and fewer readings

Workout setup Battery approach Workout data and features
Standard workout behavior Does not use the specific reduced-reading combination described above; actual battery use varies. Retains the standard workout behavior for alerts, splits, segments, and current-pace metrics.
Low Power Mode plus Fewer GPS and Heart Rate Readings Reduces GPS and heart-rate reading frequency during a supported outdoor workout; Apple says this can extend use, without specifying a fixed amount. Workout alerts are disabled; splits and segments are not recorded; current pace is unavailable.

Use the second setup when conserving charge matters more than those live metrics and workout features. If alerts, splits, segments, or current pace are important for your route, keep standard workout behavior and plan for greater battery use rather than assuming the reduced-reading mode will be acceptable.

Account for connectivity in remote areas

Signal conditions affect power use. Apple says a strong Wi-Fi or mobile signal uses less battery than a weak connection, and advises Airplane Mode when weak or no coverage will persist. Airplane Mode can affect reachability, so decide based on your communication and safety needs—not battery conservation alone. Apple Support’s Low Power Mode guidance covers this recommendation.

Do not treat the advertised hours as a hiking guarantee

Apple’s original Apple Watch Ultra specification lists up to 36 hours of battery life for a particular mixed-use test routine, not for continuous GPS hiking. That routine included 180 time checks, 180 notifications, 90 minutes of app use, and a 60-minute workout with Bluetooth music over a 36-hour period. In the stated cellular test, the watch used LTE for 8 hours and connected to an iPhone by Bluetooth for 28 hours. Apple says testing was conducted in August 2022 with preproduction hardware and prerelease software, and that actual results vary with use, configuration, cellular network, signal strength, and other factors. Apple Watch Ultra technical specifications.

#1 Best Overall
Apple Watch Magnetic Fast Charger to USB-C Cable (1 m) ​​​​​​​
  • 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.
  • Compatible with all Apple Watch
  • USB-C Cable Length: 1m or 3.2 feet

That figure applies to the original Ultra specification described there. It should not be carried over to every later Ultra generation; check the current specification for your exact model. A hike’s workout duration, settings, connectivity, and the watch’s condition all differ from Apple’s test routine, so the page does not establish how many hours a specific route will last.

Plan charging before the trail

Charge fully before departure and, if your itinerary includes a resupply stop with power, consider bringing the correct Apple Watch magnetic charging cable for your model. Apple lists a USB-C magnetic fast-charging cable in the Ultra specifications. A cable or charger does not extend active runtime unless you can connect it to a power source.
