'Why does my Apple Watch die so fast?': How to improve the battery life on your Apple Watch in 7 ways

If your battery is running out faster than it should, it's possible that there's something wrong with how your watch and phone are paired.

You can resolve a lot of issues by un-pairing your watch and then re-pairing it as a new watch, which should wipe out any of the corruption that caused the battery glitch.

Here's how to do it.

1. Start the Watch app on your iPhone.

2. On the "My Watch" tab, tap your watch at the top of the screen.

3. Tap the little "i" to the right of your watch information.

4. Tap "Unpair Apple Watch" and then confirm your choice.

Now that your watch is no longer paired to your phone, follow the instructions in our article "How to pair an Apple Watch with your iPhone" to set up your watch as a new device.

Sending a lot of notifications to your watch can also seriously drain your battery. You should only enable the most essential notifications.

1. Start the Watch app on your iPhone.

2. On the "My Watch" tab, tap "Notifications."

3. For each app listed on the Notifications page, tap the app and specify whether it should be allowed to send notifications. Some apps default to "Mirror my iPhone." If that's the case, change the setting to "Custom," and you will be able to fine-tune the notifications.

When the Apple Watch is in workout mode, it uses a little extra battery power, since it measures your heart rate continuously, instead of every few minutes.

If your watch doesn't realize your workout has ended for a while, it can keep running at higher power longer than needed.

Instead, get in the habit of ending a workout manually by swiping the screen to the right and tapping "End." For more information, see our article "How to start a workout on your Apple Watch in 2 different ways."

When Background App Refresh is on, apps can exchange data between the iPhone and Apple Watch, so they always have current data when needed.

This can affect battery life, of course, so you can turn the feature off entirely, or select specific apps.

1. Start the Watch app on your iPhone.

2. On the "My Watch" tab, tap "General."

3. Tap "Background App Refresh."

4. On the Background App Fresh page, you can disable the feature entirely by swiping the button at the top of the screen to the left. Or, you can enable and disable specific apps so only the apps most important to you get refreshed automatically.

This feature controls some graphical effects and animations which can drain the battery.

1. Start the Watch app on your iPhone.

2. On the "My Watch" tab, tap "General."

3. Tap "Accessibility."

4. Tap "Reduce Motion."

5. Turn on "Reduce Motion" by swiping the button to the right.

If you have tried all these tips and your Apple Watch is still unable to last all the way through the day, it's likely that there's a hardware problem with your Apple Watch — the battery may even be defective. Contact Apple customer support for servicing.
