While some brands sell smartwatches that last for days, the Apple Watch typically lasts less than a day, with the Ultra 2 lasting 36 hours with normal use. The rechargeable battery inside becomes less efficient as it ages, which often leaves many Apple fans wondering, “Why does my Apple Watch battery drain so quickly?”

6 features on your Apple Watch you probably didn’t know about
From everyday use to interesting features, the Apple Watch can do so much more than what you’ve used it for in the past.
Like all lithium-ion batteries, as the battery in your Apple Watch ages, its ability to hold a full charge decreases. But you don’t need to have your Watch serviced if you notice your battery draining a little faster. Some settings can use unnecessary power without you knowing it. If your Apple Watch battery is draining faster than usual, here are 10 things you can try to conserve power on your Apple Watch.
1 Turn off background app refresh
Apps running in the background can drain your battery faster
Running apps can drain your smartwatch battery faster and are one of the most common causes of reduced battery life. According to Apple, turning off background app refresh can help your Apple Watch battery last longer. You can turn off background app activity altogether, or toggle the setting for each app. Apps that appear on your watch face will continue to work even if you turn off background activity.
To turn off apps running in the background, open the Apple Watch app on your iPhone. Go to My Watch > General > Background App Refresh. Use the toggle switch to turn off all background activity or for each app one at a time.

Checking your statistics less frequently can help prevent battery drain
Workouts are one of the main battery drains on smartwatches: When you exercise, your Apple Watch uses more power to monitor your heart rate and map your progress with GPS.

Apple introduced Low Power Mode in WatchOS 9, which allows you to reduce power consumption by turning off things like Always-On Display and heart rate notifications while still tracking your workouts. Low Power Mode is different from Power Saving Mode, which turns off everything except the visible clock. To turn on Low Power Mode, go to the Settings app on your Apple Watch, tap Battery, and toggle Low Power Mode on. You can also access this mode by going to Control Center and tapping the battery percentage icon.
