Turn off features you don't use every day

The fastest way to extend your Apple Watch battery is to disable the features that drain it most. Always-On display, raise to speak for Siri, and background app refresh are the three biggest power consumers. You don't need to turn them all off — just the ones you actually don't use.

Go to Settings on your watch, then Display & Brightness. Toggle off "Always-On Display" if you're willing to raise your wrist to see the time. This single change can add 4 to 8 hours to your battery life on a typical day. If you rarely use Siri voice commands, go to Siri in Settings and turn off "Raise to Speak." For background app refresh, open Settings, go to General, then Background App Refresh, and disable it for apps that don't need constant updates — like news apps or social media.

Key Takeaways

  • Turning off Always-On Display, raise to speak, and background app refresh can extend battery life by 4 to 8 hours per day.
  • Reduce screen brightness and switch to a darker watch face to cut power use without losing functionality.
  • Turn off location services, Bluetooth, and Wi-Fi when you're not actively using them, especially during sleep.
  • Close apps running in the background and uninstall ones you haven't opened in weeks.
  • Enable Low Power Mode when your battery drops below 20 percent to stretch remaining charge through the day.

Lower your screen brightness and choose a darker watch face

Screen brightness is the second-largest battery drain on any watch. Your Apple Watch defaults to automatic brightness, which ramps up in bright sunlight but stays higher than necessary indoors. Open Settings, tap Display & Brightness, and drag the brightness slider down to 40 to 50 percent. You'll still see the screen clearly indoors, and the difference in battery life is noticeable — typically 2 to 4 extra hours per day.

Your watch face itself matters too. Animated faces, faces with weather updates, and faces that refresh every second use more power than static ones. Switch to a straightforward analog face or a minimal digital face with no complications (the small widgets that show weather, activity rings, or calendar events). If you want complications, limit them to two or three that don't update constantly. A plain black background uses less power than a bright or colorful one.

Disable location services and Wi-Fi when you don't need them

Location services and Wi-Fi both search for signals constantly, which drains the battery even when you're not actively using them. If you're not running a GPS workout or using maps, you don't need location on. Go to Settings, tap Privacy, then Location Services, and toggle it off. You can turn it back on when you plan to use it.

Wi-Fi is less obvious — your watch will try to connect to known networks automatically, which uses power. Go to Settings, tap Wi-Fi, and toggle it off unless you're at home or in a place where you regularly use Wi-Fi calling or data. Bluetooth is harder to disable without losing notifications, so leave it on if you wear your watch throughout the day. At night, when you're not wearing it, turn Bluetooth off in Control Center (swipe up from the bottom of the screen) to save power while it charges.

Close apps and remove ones you don't use

Apps running in the background consume battery even when you're not looking at them. Press and hold an app on your watch face, then swipe left and tap the trash icon to close it. Do this for any app you opened but aren't actively using. You can reopen it later if you need it — closing it doesn't delete it.

If you have apps you haven't opened in weeks, uninstall them entirely. Open the Watch app on your iPhone, go to App Library, find the app, tap it, and select "Remove App." This prevents background refresh from running on apps you've forgotten about. Focus on removing news, social media, and fitness apps you don't check regularly. Keep only the apps you use at least once a week.

Enable Low Power Mode when battery drops below 20 percent

Low Power Mode cuts off most background activity and limits notifications, but it keeps your watch functional for the rest of the day. When your battery hits 20 percent, your watch will prompt you to enable it. You can also turn it on manually by opening Control Center (swipe up from the bottom), then tapping the battery percentage and selecting "Low Power Mode."

In Low Power Mode, your watch will still show time, receive calls and texts, and run basic apps. It won't refresh apps in the background, update weather, or sync fitness data until you turn the mode off. If you're near the end of your day and your battery is low, this mode can stretch your charge until bedtime. Just remember to turn it off the next morning so your watch functions normally again.

Charge your watch correctly and monitor battery health

How you charge your watch affects long-term battery health. Use the magnetic charging cable that came with your watch, and charge it on a clean, dry surface away from heat sources. Charge it to 100 percent each night — leaving it partially charged overnight doesn't help the battery last longer. If you're not wearing your watch for more than a week, charge it to 50 percent and store it in a cool place.

Over time, all rechargeable batteries lose capacity. If your Apple Watch is more than two years old and the battery drains much faster than it used to, the battery itself may be wearing out. You can check battery health by opening the Watch app on your iPhone, going to General, then About, and looking at the battery health percentage. If it's below 80 percent and you're unhappy with the battery life, Apple offers battery replacement service at an Apple Store or authorized service provider.

Frequently Asked Questions

How long should my Apple Watch battery last on a single charge?

A typical Apple Watch lasts 18 hours on a full charge with normal use. If you have Always-On Display enabled, location services on, and many apps refreshing in the background, it may drop to 12 to 14 hours. With the changes in this guide, most people see 20 to 24 hours per charge.

Will turning off Bluetooth stop me from getting notifications?

Yes — if Bluetooth is off, your watch can't communicate with your iPhone, so you won't receive calls, texts, or app notifications. Leave Bluetooth on during the day. Turn it off only at night when you're sleeping and not wearing the watch, or when you're charging it and don't need notifications.

Does Low Power Mode delete any of my data?

No. Low Power Mode only pauses background activity and limits notifications. Your data, apps, and settings stay exactly as they are. When you turn Low Power Mode off, everything resumes normal operation and syncs with your iPhone.

Can I use my Apple Watch for workouts if I turn off location services?

Yes, but with limitations. Your watch can track distance and calories for indoor workouts without location. For outdoor runs, walks, or bike rides where you want a map of your route, you'll need location services on. Turn it on before you start the workout, then turn it off when you're done.

What's the difference between closing an app and uninstalling it?

Closing an app stops it from running in the background but keeps it on your watch — you can open it again anytime. Uninstalling removes it completely from your watch, though you can reinstall it from the App Store later. Uninstall apps you rarely use; close apps you use occasionally but not right now.
