Long outdoor workouts and audio played through the watch speaker can also use more power. Battery life varies with watch age and how you use its features, so one unusually short day does not by itself prove the battery is worn. If the change began after a watchOS update, give background tasks a few days to finish before judging whether the problem persists.
Start with the connection
When practical, keep your Apple Watch near its paired iPhone. If the watch is away from the phone, Apple says Wi-Fi uses less battery than mobile data. A weak Wi-Fi or cellular signal can also use more power as the watch tries to stay connected. If you expect to be somewhere with weak Wi-Fi or no mobile coverage, Airplane Mode may save power.

Apple does not give one runtime that applies to every wearer: battery life depends in part on the watch’s age and the features in use. Connectivity is a useful first check, especially if the drain occurs in a particular location or when you leave your iPhone behind. Apple’s battery-drain guidance explains these connection factors.
Try Low Power Mode—and know what changes
Low Power Mode is a broad, reversible way to see whether reduced background activity improves battery life. On the watch, press the side button to open Control Center, tap the battery percentage, then turn on Low Power Mode.

The mode turns off or reduces selected features, including Always On and background measurements. Some connections may be limited, and notifications can be delayed. It is useful when you need to stretch a charge, but consider whether those changes are acceptable for your normal routine. Apple describes the mode’s effects in its Low Power Mode instructions.
Reduce display and background activity selectively
Turn off Always On if your model supports it
On supported watches, open Settings > Display & Brightness > Always On and turn the feature off. This is a more targeted change than Low Power Mode. Always On is available on Apple Watch Series 5 and later, Apple Watch SE 3, and Apple Watch Ultra and later; the control will not appear on every model. See Apple’s Always On instructions for availability and setup.

Limit Background App Refresh
Open Settings > General > Background App Refresh. You can switch refresh off for all apps or disable it only for selected apps. If you use a complication for an app on the current watch face, that app may continue refreshing even after its background refresh setting is disabled. Apple documents this exception in its battery-life guide.
Check demanding workouts and audio playback
Use fewer GPS and heart-rate readings for supported outdoor workouts
For a supported watch and software version, Apple offers an option to reduce GPS and heart-rate readings during outdoor walking, running or hiking workouts. It applies when Low Power Mode is active and you start a supported workout in the Workout app. Apple’s guidance specifies watchOS 9.1 or later and Apple Watch SE (2nd generation), Series 8 and later, and Ultra and later. The setting is under Settings > Workout; fewer readings can reduce the detail or frequency of workout measurements. See Apple’s workout battery guidance for the supported behavior.

Prefer Bluetooth headphones to the watch speaker
On newer Apple Watch models, playing audio through the built-in speaker can drain the battery more quickly. Apple recommends AirPods or another Bluetooth audio device for better efficiency when listening to audio from the watch.
Give a recent watchOS update time to settle
After an update, the watch may continue update-related tasks in the background while you use it, and those tasks can affect battery life. If the drain began just after updating, wait a few days and check again before treating it as a lasting change. Apple’s troubleshooting guidance recommends this wait-and-reassess approach.

Check Battery Health and decide when to seek service
On the watch, open Settings > Battery > Battery Health and review Maximum Capacity, which indicates the battery’s capacity relative to when it was new. Rechargeable batteries have a limited lifespan, so battery condition is a more relevant check for persistent decline than a single day’s usage.
