Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitchesTo make your Apple Watch battery last longer, start with Low Power Mode, then tailor display, background refresh, connectivity, and workout settings to what you actually need. The benefit of each change varies by model, software version, signal, and use; Apple does not publish a fixed number of hours saved per tip.
Apple Support says you can maximize battery life by turning on Low Power Mode or preventing apps from refreshing in the background. Low Power Mode can also affect health measurements, notifications, connections, and display features, so consider those tradeoffs before relying on it.
16 tips to improve Apple Watch battery life
1. Turn on Low Power Mode when runtime matters
Open Control Center with the side button, tap the battery percentage, then choose Low Power Mode. It reduces or turns off selected features, which can include Always On, background heart-rate and blood-oxygen measurements, and some connections. Notifications may be delayed and emergency alerts may not arrive, so do not use it blindly if you depend on those functions. See Apple’s Low Power Mode guide.
2. Choose a duration for temporary savings
If you only need to extend runtime for a particular stretch, choose the one-, two-, or three-day duration option when enabling Low Power Mode, where available. Low Power Mode normally turns off after the watch charges above 80 percent unless a duration option applies. Check the options shown on your watch, as controls can vary by software version.

3. Limit Background App Refresh
On the watch, open Settings > General > Background App Refresh. Turn it off globally or disable it for apps that do not need to update in the background. Note that complications on the current watch face may continue refreshing even when app refresh is disabled. Apple documents this setting in its battery-life guide.
4. Turn off Always On if you do not need the dimmed display
On supported models, open Settings > Display & Brightness > Always On and turn it off. The screen will no longer remain visible in its dimmed state, so you will need to raise your wrist or interact with the watch to see the display. Availability depends on model; consult Apple’s Always On guide.
5. Lower display brightness to a comfortable level
Open Settings > Display & Brightness and reduce brightness as far as is comfortable for you. A dimmer display may be harder to read in bright conditions, and Apple does not specify a particular battery saving for this change. See Apple’s display settings guide.

6. Shorten Wake Duration
In Display & Brightness, choose a shorter Wake Duration so the screen does not stay active as long after you interact with it. You may need to tap or press a control again if you want to keep looking at the display. The available labels can differ by watchOS version.

If everyday movements frequently wake the screen, turn off Wake on Wrist Raise in the display settings. You can still wake the watch by tapping the display or using its controls, but checking the time at a glance becomes less convenient.
8. Turn off Wake on Crown Rotation if you do not use it
If rotating the Digital Crown to wake the display is not useful to you, disable Wake on Crown Rotation in Display & Brightness. This changes how you wake the screen; it does not prevent interaction by other means.

9. Keep your paired iPhone within Bluetooth range when practical
Apple Watch is most efficient when connected to its paired iPhone over Bluetooth. If carrying the phone is convenient, keeping it nearby can avoid relying on other connections. Apple explains connection behavior in its battery-drain guidance.
10. Prefer Wi-Fi to cellular when your iPhone is away
If the paired iPhone is not nearby and a suitable Wi-Fi network is available, Wi-Fi uses less battery than a mobile network, according to Apple. Connection behavior depends on the watch, network, and settings, so check the current connectivity status on your device.

11. Avoid prolonged weak-signal connections
Weak Wi-Fi or cellular coverage can use more power. If you expect to be without coverage for an extended period and do not need connectivity, Airplane Mode can save power—but it disconnects the watch. Do not use it if you need calls, messages, or other connected features.

12. Reduce GPS and heart-rate readings during some workouts
For long outdoor walks, runs, or hikes, Low Power Mode can reduce GPS and heart-rate readings on supported watches. This option requires watchOS 9.1 or later and is limited to Apple Watch SE (2nd generation), Series 8 and later, and Ultra and later. Fewer readings mean less detailed workout data. See Apple’s compatibility and battery-drain guidance.
13. Use Bluetooth headphones instead of the built-in speaker for audio
On supported newer models, playing audio through the built-in speaker can drain the battery more quickly. Use Bluetooth headphones when that tradeoff suits you. Apple discusses this behavior in its battery-drain guidance.
14. Decide whether to enable Low Power Mode when prompted at 10%
Apple Watch prompts you about Low Power Mode when the battery reaches 10 percent. You choose whether to turn it on. Consider the feature and alert tradeoffs before accepting, rather than assuming the prompt activates it automatically.

15. Give battery drain after an update a few days to settle
After a watchOS update, background tasks can temporarily affect battery life. Apple advises waiting a few days and checking again before treating the drain as a persistent fault. If the problem continues, follow Apple’s troubleshooting guidance.
16. Check Battery Health and seek service when indicated
On the watch, open Settings > Battery > Battery Health to see Maximum Capacity, which compares the battery’s capacity with when it was new. If the watch displays “Battery Needs Service” or you think it needs a replacement, contact Apple Support rather than relying on settings changes to fix battery wear. See Apple’s battery-drain guidance.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Which battery-saving approach should you try first?
| Approach | Useful when | Tradeoff |
|---|---|---|
| Low Power Mode | You need broad, temporary savings. | Some measurements, notifications, connections, or display features may be reduced or unavailable. |
| Targeted display and refresh settings | You want to keep most watch functions and adjust specific behaviors. | The display may be less convenient, or apps may show less-fresh information. |
| Connectivity, workout, and audio choices | Your use or environment makes a particular radio, workout, or audio feature unnecessary. | You may lose connectivity or receive fewer workout readings. |
| Update wait and Battery Health check | Drain is unusual or the watch has aged. | These steps diagnose a problem; they do not increase a worn battery’s capacity. |
FAQ
How can I make my Apple Watch battery last longer?
Try Low Power Mode for temporary savings, or make targeted changes such as reducing brightness, shortening Wake Duration, and limiting Background App Refresh. Choose changes based on which features you are willing to trade off.
Why is my Apple Watch battery draining so fast?
Battery use depends on the model, software, signal conditions, and how you use the watch. A recent update can involve temporary background tasks; Apple recommends waiting a few days before checking whether the drain persists. If it does, review settings and Battery Health.
Does Low Power Mode turn off Apple Watch health tracking?
It can turn off or reduce selected measurements, including background heart-rate and blood-oxygen measurements, and can affect notifications and connections. Check Apple’s current guide and consider whether you rely on those functions before enabling it.
When should I contact Apple about my Apple Watch battery?
Check Maximum Capacity in Settings > Battery > Battery Health. Contact Apple Support if “Battery Needs Service” appears or you suspect the battery needs replacement.
