Apple Watch Series 10 Offers 30-Hour Battery Life with AOD Enabled

The Always-On Display (AOD) feature in the Apple Watch Series 10 has demonstrated impressive battery performance, lasting over 30 hours when enabled. This is a notable enhancement compared to earlier models, providing a solution for those who want to check the time at a glance without needing to charge frequently.

Research by Macworld on two identical Apple Watch Series 10 devices found that with AOD activated, the battery life surpasses 30 hours. In contrast, disabling the feature can extend battery life by an additional 10 to 12 hours. This challenges the common belief that AOD significantly drains battery resources, indicating that Apple has made considerable strides in optimizing this feature since it was first introduced with the Series 5.

For context, Apple advertises an 18-hour battery life for the Series 10. The findings from Macworld suggest that the anticipated Series 11 could potentially provide even longer battery life, with a claimed duration of 24 hours under regular usage conditions. This improvement could further attract users who prioritize battery performance.

Battery Drain Comparisons

In a separate analysis, a Reddit user shared their own tests with the Apple Watch Series 7, noting that AOD reduced battery life by 26 percent. While this data highlights potential downsides of the feature, the user pointed out that other factors might play a larger role in battery drain.

Tips for Battery Preservation

Apple offers several recommendations to help users maximize the battery life of their Apple Watches. One effective strategy is to disable AOD, but there are additional methods to consider. For example, activating Power Saving Mode during workouts, which turns off the heart rate sensor, can significantly extend battery life. This feature is easily accessible through the iPhone's Apple Watch app under My Watch > Workout.

Another suggestion is to adjust the Wake Screen settings. Users who experience accidental screen activations can go to Settings > General > Wake Screen and disable the option to turn on the display with wrist movement. Instead, they can manually check the display by pressing the Digital Crown.

Maintaining Bluetooth connectivity is also recommended, as it provides a more energy-efficient way to communicate with the paired iPhone. Lastly, enabling Low Power Mode can substantially reduce the need for frequent charging by disabling AOD and background sensors related to heart rate monitoring.

Weighing the Benefits of AOD

Despite the findings from Macworld, the choice to disable the Always-On Display may not be an easy one. Many users value the convenience of having the time visible without needing to raise their wrist, particularly during activities like reading or working. Some reviewers argue that the benefits of AOD outweigh the minor battery savings from turning it off.

Current Apple Watch owners, especially those with devices showing battery degradation over 90%, might find it useful to turn off AOD temporarily to conserve battery life. However, for most users, the trade-off may not be significant enough to justify disabling a feature that enhances usability.

With the upcoming release of models like the Series 11, Apple’s ongoing improvements in battery efficiency and display technology suggest that the Always-On Display could become an even more valuable feature of the Apple Watch, effectively balancing visibility and longevity.
