Why Apple’s new audio AI features aren’t the privacy nightmare you think they are

11 September 2026 at 11:30

Macworld

With the Apple Watch Series 12 and Ultra 4, Apple is introducing some neat new audio-based AI features that seem genuinely useful and exciting.

The new S11 processor includes hardware that makes it possible to continually listen and (lightly) process audio without ruining battery life, and Apple is using that to provide four new AI-powered features. It calls these features “Audio Intelligence” because Apple can’t help but brand everything.

  • Full-time Shazam: The watch can detect music playing and automatically identify it using Shazam, displaying it on widget in the Smart Stack. Apple Watches already do this on demand, but the new thing here is that it does it continuously in the background like Pixel phones.
  • Sound recognition: The same feature you can get on HomePods and iPhone now comes to Apple Watch. You can get notified visually when your watch hears sounds such as doorbells, fire alarms, sirens, etc. You used to need your iPhone nearby to use this feature, but the Series 12 and Ultra 4 can do it independently.
  • Live Rewind: Double-tap the digital crown to see a text readout of the last 15 seconds of what was said around you. You can then ask Siri about it or save it to the Siri app.
  • Siri Recap: Get a high-level summary of an entire conversation in the Siri app, so you don’t forget specifics or need to take notes.

The first two of those features don’t really bother anyone. Those are existing features, and the only new thing is that the Apple Watch can do them in the background without iPhone intervention. The last two will be available later this year as a beta, and those are the ones that have people freaking out. Are people’s Apple Watches going to be recording you all the time?

Apple has issued a Audio Intelligence Security Overview white paper to help users understand how all this works and how it protects everyone’s privacy. It’s worth a read, but here are the highlights.

How Live Rewind works

On the Apple Watch Series 12 and Ultra 4, audio from the microphone is continuously flowing into a little buffer in the Secure Enclave. This actually happens on lots of Apple products; it’s how they know if you’ve said “Hey Siri” or not. This is a rolling buffer, where new data continuously replaces old data.

The Secure Enclave is a completely separate hardware block that is not accessible to the rest of the operating system, or any apps, or even Apple. It’s where your Face ID and Touch ID data is stored, for example.

Live Rewind will show you what you missed—privately.

Apple

When you double-press the Digital Crown, the last 15 seconds of that buffer is sent via an encrypted secure transfer to your iPhone, where an AI model transcribes it. This happens in the iPhone’s Secure Enclave, so the audio cannot be accessed by the rest of iOS, or any app, or the user, or even Apple. This is just a straight voice-to-text transcription; it doesn’t identify or label people who are speaking. The audio is then immediately discarded.

The text of the translation is then sent back to Apple Watch where it appears on the display. It is not saved unless you ask Siri about it or save it to the Siri app to revisit later. The Siri app’s data is end-to-end encrypted and synced between devices, and users can control whether conversations are automatically deleted after 30 days, 1 year, or saved forever. Apple cannot decrypt this data, even with a court order—only the user has the key.

And one more thing, an audible chime plays from the speaker on your Apple Watch when you implement Live Rewind, even if your Apple Watch is on silent or you have headphones connected.

So that’s how Live Rewind protects your privacy and those around you. Raw audio data can’t ever be accessed by the user, the system, Apple, or any apps. It’s just straight translated to text, which is then optionally saved in the end-to-end encrypted Siri app.

How Siri Recap works

Siri Recap works in a similar way, but there’s more going on. You’ll be able to leave it on all the time, only when you trigger it manually, or specify certain places or times when it can’t operate.

First, a tiny little lightweight model simply detects if a conversation is happening at all.

If it is, that encrypted and secure audio buffer is sent to the iPhone (via an encrypted data transfer) for processing. It is transcribed to condensed text, and the raw audio is then immediately discarded. It is never accessible to the OS, apps, the user, or Apple.

This transcribed text passes through a safety filter than will remove potentially harmful terms. Then it is encrypted and sent to Apple’s Private Cloud Compute servers to be summarized, along with relevent contextual data that can make the summary better (such as what music you might be listening to, a relevant calendar entry, or high-level place information like what city you’re in).

Siri recap

Apple

Private Cloud Compute generates a title and summary with key points. It removes any specific identifiable or sensitive info such as place names or financial data, while leaving generic places names like “park” or “grocery store.” That summary is then sent back to your devices, encrypted, where it is stored in the Siri app in a new Recaps tab. All data on Apple’s Private Cloud Compute servers is always discarded immediately after processing; Apple never saves any of it.

The summaries in the Recaps tab are deleted automatically after seven days unless you choose to save it.

Like Live Rewind, Siri Recap does not create a recording, does not identify speakers, and does not even create a verbatim transcript. No audio is ever accessible at any step of the process by the user, any app, or Apple.

Finally, Live Rewind and Siri Recap are not available for users under the age of 13. For users under 18 on a Child Account, access to Live Rewind and Siri Recap must be turned on by a parent or guardian.


Apple Watch Series 12 und Ultra 4 haben 4 statt 2 GB RAM

11 September 2026 at 09:59

Auf der Keynote am Mittwoch hat Apple zum ersten Mal den genauen Prozessor genannt, auf dem der S11-Chip basiert. Damit konnte man auch ganz gut angeben, denn die Apple Watch Series 12 und Ultra 4 haben eine Architektur erhalten, die Apple vom A20 Pro abgeleitet hat. So gesehen könnte die Apple Watch Series 12 in manchen Aspekten sogar schneller sein als das iPhone 17 Pro Max.

Wie viel RAM haben Series 12 und Ultra 4?

Die Größe des Arbeitsspeichers bleibt bei der Apple Watch ein Geheimnis hinter sieben Siegeln. Nur auf Umwegen kann man herausfinden, über wie viel RAM eine aktuelle Apple Watch verfügt. Für unsere Vergleichstabellen überprüfen wir die Analytics-Logs der Watch, die das iPhone speichert. Registrierte Entwickler können diese Informationen auch in Xcode einsehen. Laut einer neuen Version von Xcode haben die Apple Watch Series 12 und Ultra 4 jeweils 4 GB RAM. Die Series 11, Ultra 3 und SE 3 kommen alle nur auf 2 GB Arbeitsspeicher.

Warum braucht die Watch mehr RAM?

Wenn man die Tatsache in Betracht zieht, dass Apple der neuesten Generation seiner Watches einen aktuellen Prozessor spendiert hat, ist die Verdoppelung des Arbeitsspeichers kein Wunder. Apple bereitet seine Smartwatches auf Apple Intelligence und Siri AI vor, und dafür sind nun mal ausreichend RAM und ein schneller Prozessor notwendig. Bereits nach der Ankündigung der ersten Version von Apple Intelligence hat Apple seine Macs nach und nach mit mindestens 16 GB RAM ausgestattet. Noch kurz davor hat der Hersteller behauptet, 8 GB RAM in einem Mac seien für die meisten ausreichend.

Die Kombination aus einem neuen Prozessor, deutlich mehr RAM und möglicherweise einer etwas größeren Batterie macht die Apple Watch Series 12 und Ultra 4 zukunftssicher für kommende KI-Neuerungen. Das gleiche Muster konnte man bei den Apple Watches Series 9 bis Series 11 beobachten: Die vorgestellten Neuerungen der vergangenen Jahre, wie die Handdrehungsgeste oder Warnungen vor zu hohem Blutdruck, kamen nicht nur für die neueste Generation, sondern auch für die Vorgänger mit der notwendigen Hardware. So werden die Series 12 und Ultra 4 voraussichtlich die Software-Neuerungen der kommenden zwei Jahre erhalten.

Das Design der Apple Watch geht in die falsche Richtung

11 September 2026 at 09:50

Als Apple damals die Apple Watch Series 10 auf den Markt brachte, war die Aufregung um das „verfeinerte Design“, das „fast 10 Prozent dünner als die Apple Watch Series 7, Series 8 und Series 9“ war, groß. Zudem verfügte das Modell über ein größeres Display, wodurch das gesamte Gerät am Handgelenk eleganter und schlanker wirkte.

Nun schlägt Apple einen anderen Weg ein. Wenn Sie eine Apple Watch Series 12 kaufen, erhalten Sie denselben 42-mm- (374 × 446 Pixel) oder 46-mm-Bildschirm (374 × 446 Pixel), doch das Gehäuse ist 1 mm breiter als bei der Series 10 und 11, wodurch der Bildschirm auf Fotos aufgrund der breiteren Ränder kleiner wirkt. Hier sind die technischen Daten:

Apple Watch Series 12

  • 42 mm × 37 mm × 9,7 mm (42 mm)
  • 46 mm × 40 mm × 9,7 mm (46 mm)

Apple Watch Series 10/11

  • 42 mm × 36 mm × 9,7 mm (42 mm)
  • 46 mm × 39 mm × 9,7 mm (46 mm)

Auf dem Papier ist das natürlich kein großer Unterschied, aber es fühlt sich wie ein Rückschritt an. Wie Sie auf dem Bild oben sehen können, sind die Einfassungen der Series 12 (links) deutlich stärker ausgeprägt als bei der Series 11 (Mitte) und der Series 9 (rechts).

Normalerweise wäre eine Änderung von einem Jahr zum nächsten für die meisten Menschen uninteressant. Doch die neuen Uhren verfügen über eine Reihe cooler Funktionen, die ausschließlich den neueren Modellen vorbehalten sind (in Europa aber teilweise nicht verfügbar sind) und die Nutzer der Serien 10 oder 11 zum Umstieg verleiten könnten. Dabei erhalten sie eine Uhr, die älter aussieht als die, die sie gerade noch am Handgelenk hatten.

Es gibt keinen offensichtlichen Grund, warum die neuen Uhren größere Gehäuse haben sollten. Abgesehen von einem neuen Herzfrequenzsensor sind die technischen Daten und die äußeren Merkmale identisch, und der neue Chip dürfte effizienter sein als der des Vorgängermodells.

Seit Jahren kursieren Gerüchte, dass Apple an einer umfassenden Überarbeitung der Apple Watch arbeitet, wobei die jüngsten Gerüchte besagen, dass diese endlich nächstes Jahr erscheinen soll. Hoffen wir es, denn das aktuelle Design geht in die falsche Richtung.

Apple Says Apple Watch Live Rewind Can’t Be Used Secretly

Should your Apple Watch always be listening?

At my gym, all the signs are handwritten and friendly. In one section, a sign asks members not to drop their weights because there are downstairs neighbors.1 In the bathrooms, reminders to flush and wash hands. But throughout the gym, signs say—more directly—no live streaming. Other signs ask people to exercise consideration when recording their routines for themselves or their coaches to ensure nobody else is in their sight lines. Privacy in the gym is paramount to ensure everyone is not self-conscious and is comfortable.

Pictures of iPhone and Apple Watch with Siri Recap features: iPhone shows the recap of a conversation.
Siri Recap requires continuous audio capture, relying on Apple’s privacy protections and with no obvious disclosure to others in the vicinity.

I was thinking of my gym when I heard about Live Rewind and Siri Recap in the just-announced Apple Watch Series 12 and Apple Watch Ultra 4. These are two of the four flagship Audio Intelligence features launching in beta later this year. Both of these tools record audio continuously. Live Rewind lets you double-press the Digital Crown to receive a transcription of the last 15 seconds of conversation. Siri Recap takes notes on what it hears throughout the day and provides Apple Intelligence-generated summaries.

Both features have, understandably, freaked people out, made them angry, or caused them to shrug in resignation. Surely Apple is exaggerating the privacy protections it explains on the same page it describes the features! And if Apple is all in on recording us all the time without our consent or knowledge whenever one of its devices is nearby, the privacy game is over, isn’t it!? Everything becomes fodder for the machine; private conversations are immutable; the future is surveillance!

I’m not one for extremes, and I’ve studied Apple’s privacy and security provisions and mistakes for nearly 30 years. But I have concerns about these features from social, political, safety, and legal standpoints. Let me tackle the privacy and security first.

Hush, now

When Apple announced Private Cloud Compute in 2024, it was interesting, but it felt academic because it didn’t then release a Siri worth worrying about. In 2026, the PCC expansion with Siri AI is much more important, as Siri may send huge amounts of our personal information to the cloud to provide better answers derived from our data.2

After studying Apple’s details on PCC, I felt reassured. This is partly because one of Apple’s five pillars of PCC integrity is transparency. This is unlike many previous claims by Apple that it would be transparent. Here, they’ve stated exactly what will be available to researchers, and one researcher already found a flaw and was awarded the highest Apple bounty—$150,000. The other pillars include end-to-end encryption, barring access by Apple or other parties through cryptographic design, and no way for an external (or internal!) party to determine which PCC server is processing an individual’s data.

Apple’s promises with Audio Intelligence are somewhat different, though I find them a valid approach to minimizing invasions of one’s privacy and an attempt to reduce violations of other people’s personal sphere. Here are the fundamentals for Live Rewind and Siri Recap:

  • The features are opt-in and can be entirely disabled (with a big asterisk, which I discuss in the next section). Live Rewind has to be triggered before it can access a 15-second recording window. Siri Recap must be enabled. This contrasts with Apple Intelligence in the version 27 releases, where, unlike earlier iterations, you cannot disable Apple Intelligence.3
  • Audio isn’t recorded, nor is it stored, nor is a transcript made. As it is captured, the audio is not accessible to you, watchOS or iOS, apps, or Apple. Apple achieves this by using the Secure Exclave to process audio; after processing, the audio is immediately discarded.4

  • All of the audio processing happens on your Apple Watch and iPhone. That prevents leakage. If you engage Siri, however, some portion of the Live Rewind text could be sent to PCC under the same security protections. (Apple says “will.”)

  • Siri Recap uses PCC. The process is complicated, exposing as little information as possible within the already secured PCC environment.

  • iCloud syncing is end-to-end encrypted. You don’t need to enable Advanced Data Protection (ADP).

  • Siri Recap deletes summaries after seven days; Live Rewind’s 15-second text snippets are deleted within 30 seconds after the Apple Watch display dims. You can save Siri Recaps or export them. With Live Rewind, they are retained within the Siri app if you choose to save them or ask Siri about the text.

From a design standpoint, these measures all feel well thought out to prevent all of the egregious use cases one might imagine: Unwanted recordings! Apple analyzing our conversations to sell us stuff (or sell to third parties)! Leakage that would allow friends or strangers to access summaries, snippets, or conversations, including via internet cloud storage!

And yet. I find the above fits into the meme of “My ‘An explanation of how the Apple Watch recording what you are saying is kept private and anonymous’ T-shirt has people asking a lot of questions already answered by my shirt.”

The right to be unheard

When I’m out in public in the United States, courts have found that in most situations, I have little right to privacy. But then you can shave that down. If a neighbor points a camera from their house at my unfenced front lawn, visible from the street?Generally legal, with some exceptions related to harassment or intimidation. But if a camera points into my house through a window or into a fenced area of my property, most jurisdictions find that “not cool” (a legal term).

The audio side of this is very different. My state of Washington, for instance, is an “all-party consent” state; some states are “one-party consent” or have different rules. “One party” means anyone in the conversation (on a phone, in person, via videoconferencing, etc.) can consent, so they can record audio or have a device or system do it for them. In Washington and other all-party states, every person being recorded must consent, or it is illegal and actionable. (Recording across state lines or internationally becomes complicated.)

Screen captures cropped from Apple video introducing Live Rewind feature: server, left, reading specials; customer looking at Live Rewind on Apple Watch, right.
Even in Apple’s promotional video, they show a food worker getting their audio recorded without their knowledge, and then replayed as text once they have left tableside.

The company says it’s not “recording” or “storing” audio. But it is capturing it. Shockingly, I’m not a lawyer, so I can’t provide a legal analysis. (Presumably many privacy-focused organizations are doing deep reads of state-level statutes.) But the gut check is what I’m really going for, anyway: do these two features have the feeling of being recorded without one’s permission, even if Apple is trying to mitigate both the technical reality and the sense of it?

On the technical side, it appears that you have to enable each feature in the Watch app on the paired iPhone. Live Rewind requires enabling Siri: Live Rewind: Double Click Digital Crown. You can schedule Siri Recap by time, trigger it or turn it off using a location, or enable or disable it manually, such as through Control Center.

So let’s do the vibe check.

Live Rewind appears to be buffering audio at all times in anticipation of needing to transcribe the last 15 seconds. Apple says Live Rewind is designed to alert those around you that you’re replaying audio: when you double-click the Digital Crown, a chime sounds (ignoring any of your settings) as the Apple Watch’s entire screen is taken over with an animation that includes a microphone indicator.

However, unless Live Rewind is also a literal Time Machine, this doesn’t feel right. People are being warned 15 seconds after their audio is captured. (If Apple doesn’t mean that, it needs to clarify.) Further, it assumes that people will be keyed in to someone’s smartwatch making sounds and flashing images they should be paying attention to.

Picture of Apple Watch showing a Siri Rewind transcription
Siri Rewind effectively replays the last 15 seconds in transcription form without obtaining consent through time travel.

There’s also no “stop recording” option: if you’re being recorded by Live Rewind, you as an unrelated party—a waiter, a friend, a stranger, someone nearby, a celebrity—have no way to say “no.”

Siri Recap ostensibly is capturing audio whenever it’s active in any of the circumstances above. There’s no indication to other people that it’s running at all, and no one except the user can opt out.

Apple’s mitigations here include that no speaker is attributed, though Siri Recap identifies and anonymously labels different voices.

With Siri Recap, an Apple Watch automatically discards “potentially harmful content.” Apple defines this as content that “promotes self-harm or hateful speech, and sensitive information, such as financial data, government-assigned identifiers, authentication data, and certain personal identifiers.” I’m not sure this list is a strong argument for Siri Recap.

When using a public or private space, there should be a compelling case, even with the protections enumerated. There are already many kinds of assistive technology used by people with many kinds of disabilities to let them function better in a world often hostile to people with no or low vision or hearing.

However, the assistive case isn’t what defines Live Rewind, a useful feature of convenience that has massive privacy implications despite the way data is captured and stored. And it doesn’t help with Siri Recap at all. Siri Recap is just “life recording” without the label attached, since no audio or video is retained, and only 0.01% of a day’s conversation will likely be summarized.

These features feel like they were designed in a lab and passed through to production without enough people wondering, “Will this provoke a tremendous backlash because of the gaps in privacy that are relatively obvious?”

It’s a jungle, Jim

The best way I can conclude my analysis is by quoting Apple:

Be mindful of those around you. While audio is not recorded and stored, and no speakers are attributed, consider those around you where conversations might be private or sensitive.

Given that Apple has to warn of this, it’s the surest sign the features shouldn’t be released in this form. Apple repeats the form of the warning I see regularly at my gym… but apparently it isn’t heeding it.


  1. Improbably, there is a 24-hour recording studio downstairs. This is not a Simpsons bit. ↩
  2. Siri AI uses a combination of local, on-device AI models and cloud-based models. Starting with Siri AI, this can include Apple models trained using Google Gemini running on Google’s private cloud servers. However, as a user, you can’t opt out of using cloud AI, and you don’t know which queries or parts of queries are sent to PCC (let alone which flavor of PCC). (This is distinct from ChatGPT support, from which you can opt out, use quasi-anonymously, or use logged in to your own OpenAI account.) ↩
  3. You can only disable Siri, which also turns off Siri AI, but Apple Intelligence will continue to function in supported apps as far as I can determine. ↩
  4. This is also where Apple Pay data is stored. The Secure Exclave differs from the Secure Enclave, which is a one-way secrets holder for biometric data and device-based encryption keys, among other things. ↩

Apple Explains What Happens to Conversations Siri Recap Hears

11 September 2026 at 00:38
The Apple Watch Series 12 and Ultra 4 have new Audio Intelligence features that include Sound Recognition, Music Recognition, Live Rewind, and Siri Recap. When these features are activated, the new Apple Watches are always listening to what's going on around the wearer.


With ‌Siri‌ Recap, the Apple Watch listens to your conversations throughout the day and takes notes. It uses Apple Intelligence to continually generate summaries that Apple says are meant to "jog your memory" on events so you can stay present in the moment.

Apple anticipated negative reactions to a wearable that's always listening, so it has a detailed explainer on the privacy features that have been added.

  • No speaker attribution - ‌Siri‌ Recap will not identify and attribute speakers. Names can be included if mentioned in the conversation, but nothing is directly attributed to a specific person.

  • Omitted information - ‌Siri‌ Recaps will omit potentially harmful content or sensitive data, which Apple says includes language that promotes self-harm or hateful speech, financial data, government-assigned identifiers, authentication data, and certain personal identifiers.

  • Caveats - Apple warns that ‌Siri‌ Recap summaries can be incomplete or inaccurate, and filtering may not remove all sensitive information.

  • No transcript - Apple says ‌Siri‌ Recap doesn't produce a full transcript of a conversation. It's just a summary, comparable to notes one might jot down after a conversation.

  • Condensed conversations - Encrypted, condensed text versions of a conversation are sent to Private Cloud Compute. The text is less than half the length of the original transcript, and distills the conversation to its core meaning. Conversation tone, non-essential language, filler words, and redundancies are removed.

  • No audio recording - Audio is sent to the Secure Exclave on Apple Watch and iPhone for processing and analysis. It can't be accessed by the operating system, apps, the user, or Apple, and no audio is recorded or stored.

  • Private Cloud Compute - ‌Siri‌ Recap uses Apple Foundation Models running on Private Cloud Compute to summarize and format the final output. Data is not accessible to Apple or anyone else.

  • Opt in, not opt out - ‌Siri‌ Recap can be turned on in the Apple Watch app on iPhone, and set to listen on a schedule. You can have it on only at work, or set it to never listen at night. There will be a quick access toggle in Control Center for turning it on and off.

  • Auto-delete - Summaries auto-delete after seven days if not saved to the ‌Siri‌ app.

  • Siri app - Summaries are saved to the ‌Siri‌ app and can be deleted at any time from all synced devices. Saved summaries can be exported to other apps like Notes.

  • Encryption - Summaries are end-to-end encrypted when synced to your other devices via iCloud so only your trusted devices can access them.


Apple suggests that Apple Watch wearers "be mindful" of the people around them. "While audio is not recorded and stored, and no speakers are attributed, consider those around you where conversations might be private or sensitive," reads Apple's document.

‌Siri‌ Recap requires one of the new Apple Watch models and an iPhone 16 or later (except the iPhone 16e). The feature is launching later this year.

You Can't Use Apple Watch's Live Rewind Secretly, Apple Says

10 September 2026 at 23:11
With the Apple Watch Series 12 and Ultra 4, Apple is adding Live Rewind, which relies on an S11 processor and new continual listening features.


Live Rewind listens to what's happening around the wearer, and when activated with a double press on the Digital Crown, offers a transcript of what was said in the last 15 seconds. Apple says the feature will let users catch something they missed or are less familiar with. Snippets can be referred to Siri for further evaluation or saved to the ‌Siri‌ app.

Apple users are already expressing privacy concerns about Live Rewind, and likening it to Meta's much-maligned smart glasses, but no Apple Watch user will be able to activate it surreptitiously.

When the Digital Crown is pressed for Live Rewind, the Apple Watch will sound an audible chime from the speaker. The chime will sound even if the Apple Watch is on silent or if headphones are connected. At the same time, a full-display animation and microphone indicator will appear, with the combination meant to alert those nearby that the feature has been activated.

Apple says Live Rewind only activates with a deliberate press on the Digital Crown and all processing is done on-device. It shows the last 15 seconds of speech as a text snippet on the display, and does not continue to transcribe in the background. It can be turned on or off through the Watch app on the iPhone.

The Apple Watch Series 12 and Ultra 4 have an S11 chip equipped with a Secure Exclave. Apple describes the Secure Exclave as a hardware-isolated compartment that processes sensor data separately from the rest of the system. Data processed and analyzed in the Secure Exclave is not accessible by the operating system, apps, the user, or Apple.

Live Rewind and other Audio Intelligence features do not generate audio recordings. Audio flows into the Secure Exclave, is processed, and then deleted.

According to Apple, Live Rewind text snippets "disappear permanently" from the Apple Watch approximately 30 seconds after the Apple Watch display dims, unless the info is saved to the ‌Siri‌ app.

Live Rewind requires an Apple Watch Series 12 or Apple Watch Ultra 4 paired with an iPhone 16 or later, though the iPhone 16e is not compatible. Apple Intelligence and ‌Siri‌ AI are required, and the feature is not available for users under 13. The feature will launch later this year and won't be in the initial versions of watchOS 27 and iOS 27.

Ceramic Series 12 is Pricier to Repair Than Apple Watch Ultra 4

10 September 2026 at 21:31
Apple reintroduced a ceramic case for the Apple Watch Series 12, but if you don't have AppleCare+, repairs are unusually expensive.


It costs $599 to fix "other damage," which covers any repair besides a battery replacement. Battery service is priced at $99.

Repairing a ceramic Series 12 is more expensive than getting an Apple Watch Ultra 4 repaired. That repair costs $549 without ‌AppleCare‌+ (up $50 from the prior model). A repair for a cellular aluminum Series 12 of the same size is $349.

Apple Watch Series 12 models in the Pearl White or Night Blue ceramic options are priced starting at $899, while the ‌Apple Watch Ultra 4‌ is priced starting at $799.

With ‌AppleCare‌+, Apple Watch users will only need to pay a $69 service fee for damage to the ceramic Apple Watch Series 12 or $79 for the ‌Apple Watch Ultra 4‌. Battery service is free if a watch's battery capacity drops below 80 percent, and theft or loss has a $119 deductible.

‌AppleCare‌+ with Theft and Loss for the Apple Watch Series 12 is $4.99 per month, and it's $5.99 per month for the Ultra 4. Customers can also opt for ‌AppleCare‌ One, Apple's $19.99 per month option that covers up to three devices. Starting on September 14, Apple is also offering ‌AppleCare‌ One Family, which is $49.99 per month for up to six family members.

Upgrading to Apple Watch Series 12 Could Cost You Hypertension Notifications

10 September 2026 at 20:33
Some Apple Watch users who upgrade to the Series 12 or the Ultra 4 might temporarily lose access to hypertension notifications.


On the watchOS feature availability page, Apple says notifications might not be available on the Series 12 or Ultra 4 at launch because regulatory clearances are in process.
Hypertension Notifications may not be available on Apple Watch Series 12 or Ultra 4 in your region, as additional regulatory clearances for these devices are in process.

The warning applies to 33 countries and regions, including Canada, Australia, India, Brazil, Singapore, Japan, Taiwan, South Africa, South Korea, and the UAE, with a full list on Apple's website.

The Apple Watch Series 12 and Apple Watch Ultra 4 have revamped sensors and a new Health Sensing System. Apple added new optical and electrical heart sensors for more frequent and accurate tracking, and the change appears to require new regulatory approval in some locations.

What's new:

  • ECG - The electrodes in the watch cover more surface area for improved skin contact during ECG readings.

  • Optical sensing - Redesigned photodiodes are organized in a ring to capture light more efficiently.

  • Heart rate measurement - Larger, power-efficient green LEDs in the optical heart rate sensor allow the new watches to measure heart rate every five seconds all day, offering more data on a user's fitness and physiological state. Real-time heart rate is available in the updated Heart Rate app, and Exercise and Move Activity rings are more accurate. HRV is also measured as often as every five minutes.


Apple Watch users who get these notifications today may lose the option when upgrading to the Series 12 or Ultra 4 until regulatory clearance is granted.

Countries not on Apple's list with a footnote will continue to get notifications as usual. This includes the United States, UK, and all EU countries.

Apple Watch Series 12 Received a Price Increase You Might Have Missed

10 September 2026 at 19:11
Ever since the Apple Watch Series 4 in 2018, the larger-sized aluminum Apple Watch has started at $429 in the U.S., but that has changed with the Apple Watch Series 12.


While the Apple Watch Series 12 with a 42mm case maintains a starting price of $399, the 46mm model has received a $20 price increase and now starts at $449.

In other words, stepping up to a 46mm case now costs an extra $50 instead of $30.

Apple products are getting more expensive lately. Amid a RAM chip shortage, the company raised prices on several existing iPhone models this week, after raising prices on Macs, iPads, HomePods, the Apple TV, and more in June. Plus, the starting prices of the iPhone 18 Pro models are $100 higher in the U.S. compared to the iPhone 17 Pro models.

Apple Watch Series 12 and Apple Watch Ultra 4 models have increased RAM, according to Xcode.

Ceramic Apple Watch Series 12 Is Bigger and Heavier Than Other Models

10 September 2026 at 18:00
Apple Watch Series 12 models with a ceramic case are physically larger than the same model in aluminum or titanium, according to Apple's own tech specs.


At 46mm, Apple's tech specs page lists the aluminum and titanium case at 46mm by 40mm by 9.7mm, while the ceramic case sold under the same 46mm name measures 47mm by 41mm by 9.85mm, a millimeter taller, a millimeter wider, and 0.15mm thicker. The 42mm size follows the same pattern: 42mm by 37mm by 9.7mm for aluminum and titanium, versus 43mm by 37mm by 9.85mm for ceramic, a millimeter taller and 0.15mm thicker, with the width unchanged.

The display is unaffected. Apple lists the same 1,196 sq mm display area at 46mm and 970 sq mm at 42mm across all three materials, meaning the extra size is entirely case, not screen.

The ceramic models are also heavier. At 46mm, the Pearl White ceramic case weighs 51.3 grams and Night Blue weighs 52.9 grams, against 39.5 grams for the equivalent aluminum model and 44.9 grams for titanium, up to 34% heavier than aluminum and 18% heavier than titanium. The 42mm ceramic models weigh 41.7 grams in Pearl White and 42.8 grams in Night Blue, against 32.2 grams for aluminum and 36.5 grams for titanium, up to 33% heavier than aluminum and 17% heavier than titanium.

This appears to be the first time Apple has sold different physical case dimensions under the same nominal watch size. The increased size is presumably a design compromise owing to the entirely different material, although the earlier ceramic Apple Watch Edition models used identical case dimensions across materials at a given size, with only the weight changing between them.

Ceramic returns to the Apple Watch lineup with the Series 12 after a six-year absence, having last been offered on Series 5 in 2019 before Apple dropped it for Series 6 in 2020.

Apple Watch Series 12 in ceramic starts at $899, compared with $399 for aluminum and $699 for titanium, in Pearl White or Night Blue finishes. It launches on September 18.

Apple Watch Series 12 Has Smaller Screens and Bigger Cases

10 September 2026 at 16:52
The Apple Watch Series 12 pairs a smaller display with a wider case than Series 10 and Series 11, even though the pixel resolution hasn't changed, according to Apple's own tech specs.


For the 46mm Series 12, Apple's tech specs page lists the display area at 1,196 sq mm, down 2% from 1,220 sq mm on Series 10 and Series 11. The 42mm size shows a similar 1.9% drop, from 989 sq mm to 970 sq mm. Pixel counts are identical across all three generations: 416 by 496 at 46mm, and 374 by 446 at 42mm.

The case grows as the screen shrinks. Apple's Series 12 tech specs list the 46mm case at 46mm by 40mm by 9.7mm, a millimeter wider than the 46mm by 39mm by 9.7mm case on Series 10 and Series 11, a roughly 2.6% increase in case footprint. The 42mm case grew from 42mm by 36mm to 42mm by 37mm over the same span, about 2.8%, with depth unchanged at 9.7mm for both sizes.

A smaller display combined with a bigger casing means bigger borders around the display, and it looks like Apple has also tweaked the design of the Series 12 to recede the casing and expand the front glass, which makes the borders look even larger.

There's recent precedent for a change like this translating into a visibly thicker bezel. Series 10 went through a similar shift when it replaced Series 9 in 2024, growing the case around the display. The Series 10's visible aluminum edge had actually shrunk by around 33% versus Series 9, while the total bezel, including the black glass border, had grown by about 17%, even though the case and display figures looked like an improvement on paper.

It looks like the Series 12 repeats that pattern, although to a less extreme extent. Unlike the Series 9 to Series 10 change, which was a full case redesign, Series 10, Series 11, and Series 12 all share the same approximate case design. The Apple Watch Series 12 starts at $399 and launches on September 18.

iPhones 18 Pro têm 12GB de memória; novos Apple Watches agora têm 4GB

10 September 2026 at 16:07

Aos poucos, informações sobre os novos produtos da Apple — que geralmente não são detalhadas pela empresa — vão sendo reveladas. Ontem, por exemplo, comentamos por aqui as capacidades oficiais das baterias dos iPhones 18 Pro/18 Pro Max.

Agora, essas informações abordam as quantidades de RAM 1Random access memory, ou memória de acesso aleatório. que os novos dispositivos possuem — não só dos iPhones, mas também dos Apple Watches Series 12 e Ultra 4.

No caso dos iPhones 18 Pro/18 Pro Max, temos a mesma quantidade de memória que os iPhones 17 Pro/17 Pro Max — conforme informações vistas pelo MacRumors na versão mais recente do Xcode 27.

  • iPhone 18 Pro: 12GB
  • iPhone 18 Pro Max: 12GB

Ainda segundo a reportagem, o Xcode ainda não oferece suporte ao iPhone Duo, mas como o dobrável utiliza o mesmo chip A20 Pro dos iPhones 18 Pro, é provável que ele também possua 12GB de memória.

Eles também confirmaram que os novos Watches têm uma quantidade maior memória do que os seus respectivos antecessores.

  • Apple Watch Series 12: 4GB
  • Apple Watch Ultra 4: 4GB

Os Apple Watches Series 11 e Ultra 3, cabe lembrar, possuem 2GB de RAM — portanto, os novos modelos contam com o dobro de memória.

Apesar da grave escassez de chips de memória — que levou a Apple a aumentar os preços de iPhones, iPads, Macs e outros produtos nos últimos meses —, as linhas Series 12 e Ultra 4 mantiveram os mesmos preços iniciais das linhas Series 11 e Ultra 3.
