The Apple Watch has been a game-changer in the wearable tech space, but its daily charging requirement is a significant pain point. While it boasts impressive accuracy in health metrics, the need to recharge it overnight often leads to missed data collection, especially for valuable long-term health insights. This is where smart rings and screenless bands like the Oura Ring and Whoop Band step in, offering a solution that stays on your body for extended periods, capturing health trends that a smartwatch might miss.
Personally, I've found the Apple Watch to be the most accurate wearable for heart rate testing, but its battery life is a constant frustration. I've never managed to consistently wear it to bed, and I'm not alone in this struggle. Many people choose other wearables simply because they can wear them around the clock, and Apple is missing out on this opportunity.
The issue with battery life is complex. While the Apple Watch excels in accuracy due to its sensors, algorithms, and sampling frequency, its battery life is limited. Smart rings, on the other hand, have smaller batteries, which means they take less frequent samples, but this can be a trade-off for capturing sudden spikes during interval training.
Apple's sensors and software can already provide many of the same long-term health insights as a smart ring, but these insights depend on consistent overnight wear. This means remembering to charge the watch before bed and not accidentally forgetting it on the charger, which is a common issue.
The Oura Ring 5, for example, lasts a week or more on your finger, uninterrupted, before needing a charge. This means you can see your ovulation data as it happens, rather than retroactively like the Apple Watch. As a woman trying to better understand my cycle, this continuity has made it much easier to connect the dots between my hormones, sleep, recovery, and workouts.
While battery advancements are on the horizon, they won't push the Apple Watch to week-long battery life anytime soon. If Apple wants to achieve this without sacrificing accuracy, it may need to develop an entirely new wearable device, like a smart ring.
A watch-ring combo could be the winning formula, with the watch for notifications, workouts, and live training data, and the ring for long-term health data. This approach would require buying multiple devices, but it's a strategy that Samsung and Google are already exploring.
Apple wouldn't be starting from scratch with a smart ring. It already has the health infrastructure in place through the Health app, years of biometric algorithms, and more than a decade of Apple Watch development. The challenge is whether it can catch up with the established players like Oura and Whoop, who have spent nearly a decade refining their hardware and understanding of health.
The biggest argument against an Apple Ring has always been cannibalization of Apple Watch sales. However, with the global smart ring market projected to grow significantly, it's a category that's becoming hard to ignore. Apple has successfully expanded the iPod category with minimal cannibalization of sales, and it may be time to consider a smart ring as well.
In the longer term, an Apple Ring doesn't seem so far-fetched anymore. While I'd still bet on Apple doubling down on the Apple Watch in the near term, the Infinite Loop (my name for the hypothetical Apple Ring) could become a reality, and I'd be first in line.
