I Put the Apple Watch Ultra 2 Battery to the Test in Multiple Scenarios. Here’s what I found
Key Ultra 2 Battery Insights:
- Max Battery Life Potential: By turning off ‘Always On Display’, ‘Raise to Wake’, and forgoing sleep usage, you can achieve a 20% longer battery life, reaching up to 84 hours.
- Features Impact: Using the watch for sleep, having the ‘Always On Display’ and ‘Raise to Wake’ enabled can reduce battery life by 33%, giving you around 56 hours.
- Sleep Tracking Impact: Using the watch for sleep tracking reduces battery life by approximately 8% compared to not using it for sleep with similar settings.
- Always On & Raise to Wake: Having both features activated together can contribute to a 28% decrease in battery life.
Disclaimer: The results presented in this article were based on real-world usage and varied daily activities. While a controlled setting would yield more accurate results, these findings reflect everyday use and encompass factors like workout durations, messaging, among others.
Apple Watch Ultra 2 Battery Test
- Sleep Mode off, Always-On display and Raise-to-Wake on, brightness at 2/3.
- Sleep Mode off, Always-On and Raise-to-Wake off, brightness at 2/3.
- Sleep mode on, Always-On and Raise-to-Wake off, brightness at 2/3.
- Sleep mode on, Always-On display and Raise-to-Wake on, brightness at 2/3.
My daily use consists of timers, checking dozens of notifications, 1 hour-long weightlifting and 30 minute walk 6 days per week, alarms, texting, and adjusting various settings.

Conclusions and Recommendations:
The Apple Watch Ultra 2 offers impressive battery life for the functionality it offers, but its longevity is heavily influenced by the combination of features and settings used, many of which put a heavy strain on the processor.
Users should optimize their settings to get the most out of their device based on their personal needs and preferences.
- Turn Off ‘Always On Display’ and ‘Raise to Wake’: These were the most significant battery-drainers in our tests. Disabling them can add up to 28 hours of battery life.
- Reconsider Sleep Usage: If you can forgo sleep tracking, you could save up to 7 hours of battery.
- Brightness Matters: We tested at a consistent 2/3 brightness. If you can tolerate dimming the display to 1/3, there will be potential for even longer battery life. Conversely, setting the brightness to 100% will result in even more battery drain.
