How to Maximize Battery Life

It’s important to know how to get the most out of your Apple Watch battery because a dead watch can’t do much. There are a few key things you can do to maximize your battery life. One is to dim your screen or turn on Auto-Brightness. You can also turn off the heart rate sensor, disable Wi-Fi and Bluetooth when you’re not using them, and use Power Saving Mode.

Use Low Power Mode

When your Apple Watch is running low on power, you can use Low Power Mode to extend the amount of time that you have to use your watch. Low Power Mode reduces the amount of time that the display is turned on, and disables some features that are not essential, such as Mail fetch and Hey Siri.

To turn on Low Power Mode, open the Settings app on your watch, tap Battery, then tap Low Power Mode. You can also turn Low Power Mode on from the Control Center.

When Low Power Mode is on, the battery icon in the top-right corner of your watch face turns yellow and a yellow battery indicator appears at the top of the screen when you view apps.

Reduce Screen Brightness

Dark Mode can also be found in the display settings of your Apple Watch. This nifty little trick not only looks great, but can also conserve battery life By default, your Apple Watch will automatically switch to Dark Mode at sunset, but you can also manually enable it whenever you want from the watch face settings.

Minimize Use of Apps

One thing that will suck the life out of your battery quickly is opening and using apps. Anytime the Watch’s display turns on, it’s going to use power. Use apps sparingly to help preserve your charge.

Your best bet is to only open apps when you absolutely need them, and close them as soon as you’re done. To do this, just double press the Digital Crown, then scroll through the app carousel until you find the app you want to use. Tap on it to open it.

When you’re done, press and hold the side button, then swipe up on the app to close it.


After testing all of the different Watch models and configurations, we found that in general, you can expect the Watch to last about 18 hours before it needs to be recharged. This includes checking the time frequently, receiving notifications, using apps, and completing a 30-minute workout. If you use your Watch less frequently, you can stretch its battery life to two or three days.
