Apple Watch Series 12 and Ultra 4: A Closer Look at New Features and Performance

The first impressions of the Apple Watch Series 12 and Apple Watch Ultra 4 are out just in time for their launch this Friday, September 18. While at first glance, the exterior may appear similar to their predecessors, there’s more than meets the eye within. This incremental update might leave some Apple enthusiasts longing for more, but it does introduce significant technical improvements and potential benefits for users.

Performance Upgrades: The S11 Chip

An upgraded S11 chip powers both models, enhancing their performance significantly. This is not just about speed; it’s about a more stable and efficient user experience. The optical heart sensor now utilizes larger LEDs, leading to improved accuracy in heart rate monitoring. This is particularly beneficial as consumers increasingly prioritize health metrics in their wearable tech. Notably, heart rate variability (HRV) readings can now occur up to 24 times more frequently. For fitness aficionados and those monitoring their cardiovascular health, this new capability provides a more granular view of their heart performance, enabling data-driven decisions about their well-being.

New Features: The Readiness App

A standout addition is the new Readiness app, which continuously updates step tracking throughout the day and provides real-time feedback. This is a shift away from static health reports, which, while informative, lack the immediacy that many users crave. Apple has also introduced faster charging capabilities; while it doesn’t extend battery life beyond the Series 11's 24-hour mark, it compensates well for daily users who might find themselves rushing out the door. Quick charging means users can get back to tracking without missing a beat.

Siri's Performance Boost

As The Verge's Victoria Song notes, the S11 chip has dramatically improved the responsiveness of Siri. In a world where voice interaction is pivotal for many devices, Siri’s speed in processing queries improves the overall experience significantly:

"The S11's impact was also noticeable in testing. Siri AI queries are faster on the Series 12 than my Ultra 3."

What you’ll often hear is that performance upgrades like these make the device more user-friendly. The fact is, smooth interactions with virtual assistants can elevate user satisfaction. Plus, this performance upgrade coincides with a significant feature in heart rate tracking. According to Song, the intense tracking doesn’t impair battery life, which often plagues wearables:

"I didn't notice a negative impact to battery life from continuous heart rate tracking. People will gripe that the Series 12 doesn't have multi-day battery and sticks to the Series 11's 24-hour battery estimate. But like last year, I maintain that faster charging is a fine enough solution. In a 20-minute charging test, I went from 20 to 64 percent battery."

That said, will the battery life hold up under extended daily usage? This remains a key question for potential buyers.

Battery Expectations: Ultra 4 Performance

9to5Mac's Chance Miller found that the Ultra 4 lives up to its battery life promises, demonstrating a remarkable 48-hour performance on a single charge, even with workout tracking and sleep data collection. The implications of such a capability are profound for those engaged in multi-day activities or who simply prefer not to hassle with daily charging:

"In my real-world test, I charged it to 100% around 8 p.m. on Sunday and didn't put it back on the charger until 8 p.m. on Tuesday."

For users who lead busy lives, having that level of endurance means greater flexibility and fewer interruptions.

Readiness Score: An Edge in Tracking

Vanessa Hand Orellana from CNET highlights the Apple Watch's ability to provide a continuously updated readiness score, giving it a distinctive edge over devices like the Oura Ring. Traditionally, many wearables provide static morning reports based on overnight metrics. Apple’s integration offers regular updates throughout the day, eliminating the need for a subscription:

"Many wearables give you a score in the morning based on metrics such as HRV, sleep, temperature and other overnight vitals, but since it's static and delivered once a day, it can feel like a life sentence ... The Apple Watch keeps measuring your daytime vitals and adjusts your Readiness score as the day unfolds."

This feature offers real-time insights, catering to those whose routines may change during the day. However, there’s a catch: the app requires a minimum of seven nights of sleep data for the initial readiness score, with reviewers reporting varying results on its usability. That’s a hurdle for those eager to start tracking immediately.

Pending Features: What’s Missing?

The anticipated Siri Rewind and Live Recap features are currently not accessible to testers, reflecting the ongoing development of the watchOS update. This could dampen the excitement for some users. It suggests Apple may be prioritizing functionality over feature quantity. In a market filled with flashy updates, this stance might seem prudent, but it’s a delicate balancing act to maintain user engagement.

Even without these newer features currently available, Engadget's Cherlynn Low classified the new devices as meaningful enhancements this year:

"If you can ignore the Live Rewind and Siri Recap features that aren't even available on the Apple Watch Series 12 yet, the device is a solid upgrade over older models."

Style and Customization Options

Both watches expand on style options, introducing new colors like Light Bronze aluminum and reviving older finishes such as Pearl White and Night Blue ceramic. This kind of aesthetic appeal is significant in the smartwatch sector, where personal expression often drives purchasing decisions. If you’re in this space, knowing you have a unique look boosts the watch's desirability.

Implications and Future Outlook

What this means for you, the consumer, is that Apple seems to be honing in on performance and personalization while sticking to established battery life norms. This attention to detail may keep Apple ahead in a competitive market, but it raises questions about how much longer consumers will settle for incremental updates. If the trend continues toward minor enhancements rather than significant leaps, loyal customers might start looking elsewhere for innovation.
