Apple Watch Series 12: Most Accurate Heart Rate Sensing in a Wearable

Apple Watch Series 12: Most Accurate Heart Rate Sensing in a Wearable

Apple has unveiled the Apple Watch Series 12, featuring a new Health Sensing System and the S11 chip, delivering the most accurate heart rate sensing of any wearable. It measures heart rate every five seconds and HRV up to 24 times more often, enabling a new readiness score. A redesigned Health app with a Longevity tab and Health Age arrives later this year, alongside Audio Intelligence features for conversation recall and sound alerts. watchOS 27 brings Apple Intelligence to Siri on the wrist. Pre-orders start today, with availability September 18.

Apple Watch Series 12 is the most advanced health and fitness companion we’ve ever created.

    The audio note taking feature is extremely off-putting to me and can't believe it was so prominently showcased.

    It's made even worse by the fact that only the newest watches support this, but their external designs are unchanged from past ones, so there's no way to tell who's always listening to everything (I have an Ultra 2, likely my last one).

    Is this something most people want?? At the very least I'd appreciate a notification like the unknown airtag thing to tell me I'm being eavesdropped.

    Apple Watch is hitting diminishing returns feature-wise. I'm happy with my Series 11 but "it has more accurate heart sensors" isn't really revolutionary, and I believe some of the Apple Intelligence features will be backported anyways.

    With fast charging, battery life hasn't been an issue; I just put it on the charger while in the shower and that does the trick.

    On what legal footing does this recap feature stand? In fairly certain there are a non-zero amount of laws prohibiting audio recording without consent. And this wrist mounted always listening thing is likely to end up in a lot of places it should not. Probably burried in the end user agreement that it is 100% the users fault.

    Moved to Garmin.

    Maybe less powerful but battery life is the most important feature for me.

    Maybe it's just a general fatigue from AI, notifications, microphones, and cameras everywhere, but I'm pretty sure my next watch will be something from Germany or Switzerland containing springs and gears.

    Apple killed support for three generations of Apple Watch hardware with its latest OS update: Series 6, Series 7, Series 8, and the original Apple Watch Ultra.

    So much for its commitment to the environment, perfectly capable hardware is being sent to the bin.

    There's literally no new features on the watch. Adding in AI nonsense.

    I really just want an Apple version of the new Fitbit Air.

    I had an Apple Watch for five years. Battery didn't even last a day.

    I realized generally I have my phone or laptop with me all the time anyway, I don't need a watch with weather or app widgets.

    So in June I bought the fitbit air and it's great. Battery life lasts about 6-7 days. No distracting screen. MUCH more comfortable to sleep with since it has no buttons and a smaller form factor.

    If Apple made their own version of the Air but with Apple Pay I would switch back over in a heartbeat.

    My left wrist had formed an indent where I wore my se3. It was not worn tight, I tried different straps. In 6 months it looks like the tissue underneath has mostly moved away. I can feel my bone when I touch it. My right arm by contrast looks full like a regular arm.

    Looked up apple watch indent reddit and I saw much more serious cases after years of use.

    I’ve worn a samsung watch for a year it didn’t leave a mark, casio watches, none. Until apple fixes that weird dome shape never wearing one again. That watch is staying in the box it came in.

    Edit: There seems to be people promoting other brands in this thread. Just want to make clear I do not recommend the samsung one either. Don’t want to be labelled as such. Just get a regular watch. Wear it when you go outside and take it off when inside. You were never using the mostly inaccurate health data anyway.

More from this day
