Hi tem127,

Welcome to Apple Support Communities. I understand you'd like to know more about the battery usage on your Apple Wacth. I know it's important to get the most from your battery; I'd like to provide some information. While both Apple Watch Series 1 and Series 3 specifications state that Apple Watch battery life can last up to 18 hours,

Battery life varies by use, configuration, and many other factors; actual results will vary. See www.apple.com/batteries and www.apple.com/watch/battery.html for more information.

To review battery usage and to be sure you're getting the most from the battery in your Apple Watch I'd suggest reviewing the suggestions below:

Tips for Apple Watch

Update to the latest software.

Always make sure your Apple Watch is using the latest version of watchOS.

  • To see if you need an update, open the Apple Watch app on your iPhone and go to My Watch > General > Software Update.
  • If an update is available, connect your iPhone to Wi-Fi, attach the charger to your Apple Watch (make sure it has at least 50% charge), and update wirelessly.

Adjust your settings.

There are a few ways you can preserve battery life on your Apple Watch:

  • During running and walking workouts, turn on Power Saving Mode to disable the heart rate sensor. To do this, open the Apple Watch app on iPhone, go to My Watch > Workout, and turn on Power Saving Mode. Note that when the heart rate sensor is off, calorie burn calculations may not be as accurate.
  • For longer workouts, you can choose to use a Bluetooth chest strap instead of the built-in heart rate sensor. To pair the Bluetooth chest strap with your watch, make sure the strap is in pairing mode, then open Settings on Apple Watch, select Bluetooth, and choose from the list of Health Devices.
  • If you’re very active with your hands and your watch display turns on more than you think it should, you can prevent the display from turning on every time you raise your wrist. Open Settings on Apple Watch, select General, select Wake Screen, and turn Wake Screen on Wrist Raise off. When you want to turn on the display, just tap it or press the Digital Crown.
  • Disabling Bluetooth on your iPhone increases the battery drain on your Apple Watch. For more power-efficient communication between the devices, keep Bluetooth enabled on iPhone.
