How to Improve Your Apple Watch Battery Life

The Apple Watch is a remarkable device that offers a multitude of features to enhance your daily life. However, one common concern among Apple Watch users is its battery life. While newer models have made significant improvements, older generations and certain usage patterns may still lead to draining the battery faster than desired.

In this comprehensive guide, we will explore a wide range of strategies and tips to help you maximize the battery life of your Apple Watch. Whether you own the latest Apple Watch Ultra or an older Series 5 or SE model, these tips will empower you to get the most out of your wearable technology.

Understanding Apple Watch Battery Life

Before diving into the tips, it’s essential to understand some key aspects of Apple Watch battery life.

Understanding Apple Watch Battery Life

  1. Battery Life Variability: The battery life of your Apple Watch can vary greatly based on your usage patterns. Activities like GPS tracking during workouts or frequent use of LTE can significantly impact battery drain.
  2. Official Battery Estimates: Apple provides battery life estimates for different Apple Watch models. As of the Series 8 release, the standard estimate for Series 8 and older models, including the Watch SE (2nd Gen), is approximately 18 hours. However, the Apple Watch Ultra offers an impressive 36 hours of battery life.
  3. Always-On Display: The always-on display feature, available in Series 5 and newer models, consumes more power. Disabling this feature can help extend battery life.
  4. Charging Time: The time it takes to charge your Apple Watch can vary depending on the model and charger. Typically, it takes around 70-90 minutes to reach a full charge using the Magnetic Fast-Charge USB-C cable for Series 7 and Series 8. However, older models like the SE (2nd Gen) may take longer.

Now that we’ve covered the basics, let’s explore 17 effective tips to improve your Apple Watch’s battery life.

1. Use Low Power Mode: One of the most straightforward ways to save battery life is by activating Low Power Mode. It can double the battery life estimate from 18 hours to 36 hours, and you might even get more out of it. Low Power Mode is compatible with any Apple Watch running watchOS 9 or later. However, keep in mind that it sacrifices features like the always-on display, Wi-Fi, cellular, and reduces notifications to once per hour. Your heart rate monitor will also be turned off, but you can still make progress towards your fitness goals. To activate Low Power Mode:

  • Ensure your Apple Watch runs watchOS 9 or later.
  • Go to the ‘Settings’ dock and tap the battery meter icon.
  • Toggle ‘Low Power Mode’ to the ‘on’ position.
  • Low Power Mode remains active until manually turned off or until the Apple Watch reaches a charge level above 80%.
  • You can also enable Low Power Mode during workouts by going to Settings > Workouts > Enable Low Power Mode.

2. Check Optimized Charge Limit: The Optimized Charge Limit feature aims to prolong your Apple Watch’s battery life by limiting the time it spends fully charged. It learns your charging habits but may limit your watch’s charge to 80%. To turn it off:

  • Open ‘Settings’ on your Apple Watch.
  • Tap ‘Battery.’
  • Tap ‘Battery Health.’
  • Turn off ‘Optimized Battery Charging.’

Low Power Workouts

3. Low Power Workouts (Ultra Only): If you own an Apple Watch Ultra and want to track long-distance walks or workouts, you can enable Low Power Mode to extend battery life during these activities. It reduces GPS and heart rate samples, potentially increasing battery life from 9 to 12 hours. However, be cautious when using this mode for activities requiring precise GPS tracking, as the reduced frequency of GPS pings may affect accuracy. To enable this mode:

  • Activate Low Power Mode.
  • Go to ‘Settings’ > ‘Workout.’
  • Select ‘Fewer GPS and heart rate readings.’

4. Disable Always-On Display: If you own a Series 5-8 Apple Watch with the always-on display feature, consider disabling it to save battery life:

  • Open ‘Settings.’
  • Tap ‘Display & Brightness.’
  • Toggle ‘Always On’ to turn the feature off.

5. Turn Off Wake on Wrist Raise (Pre-Series 5 Models): Pre-Series 5 Apple Watch models use the gyroscope and accelerometer to instantly activate the display when you raise your wrist. This can lead to unnecessary battery drain, especially in situations like watching a movie or raising your hand frequently. To disable this feature:

  • Open ‘Settings.’
  • Tap ‘General.’
  • Select ‘Wake Screen.’
  • Toggle ‘Wake Screen on Wrist Raise’ to your preference.

6. Reduce Motion: watchOS includes various graphical effects to make transitions smooth. However, these effects consume extra power. If you don’t need them, you can disable them in the Accessibility menu in the Watch app.

7. Turn Off the Heart Rate Monitor: The heart rate monitor continuously checks your pulse to improve calorie estimations, but it can drain the battery significantly. You can disable it by:

  • Opening the Watch app on your iPhone.
  • Going to Privacy > Health > Heart Rate and toggling it off.
  • Additionally, consider turning off fitness tracking if it’s not essential for you.

8. Turn Off Advanced Health Tracking: Pulse ox technology and other advanced health tracking features can also impact battery life. To turn off pulse ox:

  • Go to Privacy > Health > Blood Oxygen and toggle it off.
  • You can do the same for Temperature Sensor and Respiratory Rate tracking in this menu.

9. Disable Environmental Sound Monitoring: The Apple Watch can monitor background sound levels and issue warnings if they reach potentially harmful levels. If you don’t need this feature, you can save power by turning it off:

  • Go to ‘Settings’ > ‘Noise.’
  • Turn off ‘Environmental Noise Monitoring.’

10. Customize iPhone Mirroring: You can customize how your Apple Watch mirrors core iPhone apps like Mail, Messages, and Calendar. By selectively disabling certain mirroring options, you can reduce unnecessary notifications that drain your battery:

  • Access the My Watch pane in the Watch app.
  • Adjust Phone alerts, Message alerts, and mailbox-specific alerts according to your preferences.

11. Disable Activity Reminders: The Activity app is helpful but can bombard you with notifications. If you find them draining your battery, you can turn them off in the Activity menu of the companion app.

12. Adjust Haptic Vibrations: While haptic feedback for notifications is convenient, it consumes power. You can limit this by:

  • Going to ‘Settings’ > ‘Sounds & Haptics.’
  • Turn off ‘Prominent Haptics’ or adjust haptic strength to your liking.

Turn Off Siri

13. Turn Off Siri: Siri listens for the trigger phrase “Hey Siri” continuously when your display is on. While this hands-free feature is convenient, it can drain your battery. To disable it:

  • Go to ‘Settings’ > ‘Siri’ on your Apple Watch.
  • Turn off ‘Listen for Hey Siri.’

14. Reduce Background Refreshes: Background app refreshes keep your apps up to date but consume battery life. You can customize this feature to optimize battery usage.
