Turn off features you don't use every day

The fastest way to stretch your Apple Watch battery is to disable the features that drain it most. Always-On display, background app refresh, and continuous heart rate monitoring are the three biggest power consumers. You don't need all three running at once unless you're training or need the watch face visible constantly.

Go to Settings on your watch, then Display & Brightness, and toggle off "Always-On." Your screen will go dark between glances instead of staying lit. This alone can add several hours to a full day of use. If you don't need your apps updating in the background—checking email, weather, or news while your watch is on your wrist—turn off Background App Refresh in Settings > General > Background App Refresh. You can still open those apps manually whenever you want.

For heart rate monitoring, open Settings > Privacy > Heart Rate and turn off "Always On." Your watch will still measure your heart rate when you open the Workout app or raise your wrist, but it won't check constantly throughout the day.

Key Takeaways

  • Turning off Always-On display, background app refresh, and continuous heart rate monitoring can extend battery life by several hours in a single day.
  • Reduce brightness and enable Reduce Motion in Accessibility settings to lower power draw from the screen and animations.
  • Disable Bluetooth and Wi-Fi when you're away from your phone or home network, and use Airplane Mode during times you don't need connectivity.
  • Limit notifications and disable location services for apps that don't need them to prevent the watch from working constantly in the background.
  • Keep your watch software up to date, as Apple releases battery optimizations in watchOS updates.

Lower your screen brightness and disable animations

Your watch screen is bright and colorful, but brightness is one of the biggest battery drains on any device. Open Settings > Display & Brightness and drag the brightness slider down to 40 or 50 percent. You'll still see the screen clearly in most indoor and outdoor light, and the battery will last noticeably longer.

While you're in Settings, go to Accessibility > Display & Text Size and turn on "Reduce Motion." This disables the animated transitions between screens and app launches. Those animations look smooth but cost battery power every time they play. Turning them off makes navigation feel snappier and saves power at the same time.

Turn off Bluetooth and Wi-Fi when you don't need them

Your Apple Watch uses Bluetooth to talk to your iPhone and Wi-Fi to connect to networks when your phone isn't nearby. Both radios drain battery constantly while they're searching for a signal. If you're at home or always have your phone with you, you don't need Wi-Fi on your watch at all.

Open Settings > Bluetooth and toggle it off if you're going to be near your phone all day. Turn off Wi-Fi in Settings > Wi-Fi. The watch will still work—it will just use your phone's connection for anything that needs the internet. If you want a quick way to disable both at once, swipe up from the bottom of your watch face to open Control Center and tap the Airplane Mode icon. This turns off all wireless radios. Use it during meetings, workouts where you don't need notifications, or any time you want maximum battery life for a few hours.

Disable location services and limit notifications

Location services use your watch's GPS chip, which is a serious battery drain. Most apps don't need it. Open Settings > Privacy > Location Services and turn it off entirely, or go into individual apps and disable location for each one. You'll only need GPS on for running or cycling workouts where you want a map of your route—and you can turn it back on just before you start the Workout app.

Every notification that arrives on your watch wakes up the screen and the processor. If you get dozens of notifications a day, your battery is working constantly. Go to Settings > Notifications and turn off notifications for apps you don't need to see when ready. You can still check those apps manually by opening them. Focus on keeping only messages, calls, and calendar alerts active if you want to stay reachable but save battery.

Keep your watchOS software current

Apple releases updates to watchOS several times a year, and many of them include battery optimizations. An older version of watchOS may drain your battery faster than a newer one. Open the Watch app on your iPhone, go to General > Software Update, and check whether an update is available. If one is, connect your watch to its charger and install it.

Updates can take 15 to 30 minutes, so do this when you have time and your watch is plugged in. After an update, your battery performance may improve noticeably over the next few days as the system settles in.

Use Low Power Mode for all-day battery

Low Power Mode is a built-in setting that disables many power-hungry features at once. Swipe up from the bottom of your watch face to open Control Center and tap the battery icon. This turns on Low Power Mode, which reduces performance, disables background app refresh, lowers screen brightness, and turns off some sensors. Your watch will still tell time, show notifications, and let you make calls, but it will last much longer on a single charge.

Low Power Mode is useful when you know you won't be near a charger for a long time, or when your battery is already low and you need it to last until evening. You can turn it off anytime by opening Control Center again and tapping the battery icon.

Manage which apps run in the background

Some apps are more power-hungry than others. Fitness apps, music apps, and navigation apps use more battery because they access sensors, GPS, or audio. If you have apps you rarely use, you can prevent them from running in the background entirely. Open the Watch app on your iPhone, go to General > Background App Refresh, and toggle off the apps you don't need updating while you're not using them.

You can also remove apps you never use from your watch. Open the Watch app on your iPhone, go to My Watch, find the app, and swipe left and tap Remove. This frees up space and prevents the app from checking for updates or running background tasks.

Frequently Asked Questions

Does turning off Bluetooth disconnect my watch from my iPhone?

Yes, but only for wireless features. Your watch will still sync data to your iPhone when they're near each other, and you can still use the watch for telling time, workouts, and local apps. You just won't get notifications or be able to use Siri until you turn Bluetooth back on.

Will my Apple Watch still track workouts if I turn off location services?

Yes. Your watch will track distance, calories, and heart rate without GPS. You'll just lose the detailed map of your route. If you want the map, turn location services back on before you start the Workout app.

Can I use Low Power Mode all the time?

You can, but it reduces performance and disables some features like background app refresh and always-on display. Most people use it only when they need maximum battery life. For everyday use, turning off individual features gives you better balance between battery life and functionality.

How often should I charge my Apple Watch?

Apple Watch batteries are designed to last through a full day of typical use. Most people charge overnight, the same way they charge their phone. If you're using Low Power Mode or have disabled power-hungry features, you may be able to go longer between charges.

Does closing apps on my Apple Watch save battery?

Not significantly. Closing apps manually doesn't save much power because watchOS manages app memory automatically. Turning off background app refresh for specific apps is more effective than closing them by hand.
