As modern smartwatches grow more complex and sensor-heavy, battery life is naturally the limiting factor. While several device makers have found ways to extend battery life by opting for less complex screens, fewer sensors, and software trickery, other smartwatch companies have focused on upping charging speeds. Apple falls into the latter category, with the Series 7 boasting much faster top-ups than its predecessor. But how long does the Apple Watch Series 7, SE, and other devices’ batteries last?


According to Apple, the Apple Watch Series 7 has an “all-day battery” good enough for up to 18 hours between charges.

How long does the Apple Watch’s battery last?

As we mentioned in the introduction, Apple doesn’t focus on battery life as much as other companies. The Apple Watch Series 7 packs a quoted 18 hours of endurance between charges, but even this comes with limitations. Apple notes that this figure can be achieved with “90 time checks, 90 notifications, 45 minutes of app use, and a 60-minute workout with music playback from Apple Watch via Bluetooth.” Expect battery life to dip if you use GPS or check the time more than 90 times a day.

Apple also notes that the Series 7 will last for 1.5 hours when calling others via LTE, 11 hours when working out indoors, 11 hours when playing music from storage, or six hours when working out with GPS and LTE connected.

Notably, the smaller, cheaper Apple Watch SE also has a claimed 18-hour battery life; this includes “90 time checks, 90 notifications, 45 minutes of app use, and a 60-minute workout with music playback from Apple Watch via Bluetooth.”

Unlike the Apple Watch Series 7, the SE is only good for ten hours when working indoors, five hours outdoors when connected to GPS and LTE, and ten hours playing music from internal storage.

Apple Watch battery vs other smartwatches?

The Apple Watch lags well behind its competition regarding battery longevity. You’ll get between 1—2 days of battery life with the Galaxy Watch 4, but this mileage varies massively between use cases. The Garmin Venu 2 Plus trumps both, with up to five days on a single charge, according to our experience. Notably, the standard Venu 2 lasts longer than its updated sibling. Finally, the Fitbit Versa 3 should last around 3.5 days between charges. That’s nowhere near Fitbit’s claims, but it still trumps the likes of the Apple Watch.

Of course, if you’re looking for true battery warriors and are willing to sacrifice features for longevity, consider buying a hybrid smartwatch. The Withings ScanWatch, for instance, has a claimed month-long battery life. We got around 11 days in our review, however.

Tips for improving your Apple Watch battery life

You can improve your Apple Watch’s battery life by taking note of a few tips and tricks.

Reduce animations

If you own an older Apple Watch, give this trick a try. Open the Watch app on your iPhone > My Watch > General > Accessibility > toggle on Reduce Motion.

Close background apps

You probably don’t need all your apps chugging away behind the scenes. You can force close those you don’t need. Press the side button on the Apple Watch, and use the digital crown to scroll through apps. To select an app to close, swipe on it from right to left and hit the red close button to kill it.

Disable background refresh

The Apple Watch periodically fetches content for apps in the background, which can also drain your battery. Open the Watch app on your iPhone > General > Background App Refresh to disable it. You can now toggle off the apps you don’t want using this feature or hit the master switch to kill the feature entirely.

Lower screen brightness

A brighter screen requires more power. Open Settings > Display & Brightness > adjust Brightness using the buttons or digital crown.

Disable always-on display

Finally, if you don’t need your screen on constantly, open Settings on your Apple Watch > Display & Brightness > Always On > toggle off Always On.

Q: Why is my Apple Watch dying so quickly?
A: It could be several factors, from your display brightness, watch usage, fitness tracking, or something more integral like an iOS update or hardware fault. If you have an older Apple Watch, we’d recommend upgrading to the Series 7.

Q: Are there any other ways to conserve battery on the Apple Watch?
A: You can switch on Power Reserve mode by opening the control center, tapping the battery percentage, toggling on Power Reserve, and tapping Proceed. This will turn your Apple Watch into a barebones digital watch to conserve battery.

Q: Can I replace the battery in my Apple Watch?
A: If you’re in the US, you can replace a battery for $79 if Apple’s warranty no longer covers your watch.

Q: How can I check my battery health?
A: Open Settings > Battery > Battery Health. Check the Maximum Capacity figure to get an idea of how healthy your Apple Watch’s battery is. If it’s below 80%, you should consider replacing the battery.
