This year's watchOS 27 update will focus largely on stability, performance and smaller refinements, rather than introducing major new capabilities. Still, improvements to heart-rate tracking are coming.
Apple Leaks Digest — May 25, 2026: Gurman's Watch wake-up call, iOS 27 gets AirPlay alternatives, and AirPods Ultra takes shape
Gurman's May 24 Power On argues Apple Watch needs a real strategic shakeup — and reveals the AI health coaching feature won't ship with watchOS 27. iOS 27 adds AirPlay protocol alternatives (likely EU-only) to satisfy Digital Markets Act requirements. iPhone 18 Pro's C2 modem / 5G NR-NTN satellite story reaches consensus across 9to5Mac and Forbes. AirPods Ultra rumor sharpens: cameras, H3 chip, gesture detection, ~$299.
Today's dominant story is Mark Gurman's Sunday Power On newsletter, which lands with unusual editorial weight: not just a list of features, but a thesis that Apple has lost the thread on Watch and wearables. Alongside that, the iPhone 18 Pro satellite connectivity story has gone from supply-chain whisper to widely-sourced consensus, and the AirPods Ultra rumor has picked up meaningful hardware detail.
Apple Watch: Gurman says it needs a real shakeup
Gurman's headline claim in Power On (May 24) is that the Apple Watch is overdue for a fundamental rethink 1. His argument: the wearables market has moved toward screenless bands (Whoop, Oura), AI coaching services, and subscription health models — and Apple has been slow to respond.
More immediately actionable: the AI health coaching service that was in active engineering development as late as March 2025 will not ship with watchOS 27's initial release. Gurman says it will arrive "later in the iOS 27 cycle," which in practice means iOS 27.1 or 27.2 2.

What watchOS 27 actually includes (confirmed via Gurman):
- Heart rate tracking improvements (unspecified scope)
- A "Modular Ultra" watch face variant coming to standard Apple Watch Series models for the first time 3
- Stability, performance, and bug fixes as the primary focus — not new capabilities
- Satellite features extending from iOS 27: Apple Maps via satellite and photo sharing over satellite messaging
Credibility: Gurman has a verified track record on watchOS previews. The AI health coaching delay is consistent with the Nikkei/Bloomberg supply chain pattern of pushing unfinished health features to .1 releases.
iOS 27: four more details from the May 24 Power On
Gurman's newsletter also dropped four additional iOS 27 specifics that weren't in prior coverage 1 4:
| Feature | Detail | Notes |
|---|---|---|
| AirPods settings panel | Revamped, "much more functional, better organized and more streamlined" | No preview of specific new controls |
| Genmoji / Image Playground | Improved image quality for AI-generated emoji and scenes | Builds on existing Apple Intelligence features |
| AirPlay alternatives as default | Users can set Google Cast or other protocols as the default media-beaming option | Gurman signals this may be EU-only to satisfy Digital Markets Act requirements |
| New Siri interface | Dark color scheme, similar to Apple's WWDC 2026 promo graphics | Confirms visual overhaul beyond just the standalone Siri app |
The EU AirPlay item is notable: the Digital Markets Act now requires Apple to allow third-party protocol defaults in the EU, so this change may not reach US users at launch. Apple has a history of shipping DMA compliance as EU-regional features and later expanding them globally.
iPhone 18 Pro: C2 modem brings 5G-over-satellite that works in your pocket
The claim that the iPhone 18 Pro will feature Apple's in-house C2 modem with 5G NR-NTN (New Radio Non-Terrestrial Networks) support has been circulating since February, but it reached mainstream Apple coverage on May 24 via Forbes and 9to5Mac 5 6.
The key technical claim: 5G NR-NTN integrates satellite communication with standard 5G networks at the protocol level, meaning the phone could automatically fall back to satellite when terrestrial signal is weak — no manual sky-pointing required. Gurman has separately said Apple wants satellite to work from inside a pocket, a car, or indoors.

What's new vs. current satellite on iPhone 17:
- iPhone 14–17: satellite is emergency-only, low-bandwidth, requires manual orientation
- iPhone 18 Pro (rumored): satellite operates as a seamless 5G fallback, everyday-use capable
- Coverage: C2 modem reportedly ships across the full iPhone 18 lineup, including the iPhone Fold
Credibility: MacRumors forums tracked this claim to February; 9to5Mac picked it up in reporting May 21; Forbes amplified May 24. Multiple independent outlets now citing it. Medium-high confidence — the C2 modem is real and on track; the NR-NTN capability is the unconfirmed variable.
AirPods Ultra: cameras, H3 chip, and an AI-first pitch
Cult of Mac published a detailed AirPods Ultra rumor roundup on May 24 7, aggregating leaks from multiple sources. The core hardware claims:
- H3 wireless chip — successor to the H2 in AirPods Pro 3
- Low-resolution cameras on the earbuds, enabling Visual Intelligence without pulling out your iPhone (text reading, object ID, sign translation)
- Gesture detection via depth/proximity sensors — hand gestures control playback without pinching the stem
- Enhanced health sensors: upgrades beyond AirPods Pro 3's heart rate monitor; possible body temperature tracking
- Target price: ~$299, possibly higher
- Launch window: September 2026 alongside iPhone 18, though sources hedge this as not confirmed
The "AI-first device" framing is worth noting: this isn't AirPods Pro 4 with incremental audio upgrades — it's pitched as a screenless interface for Apple Intelligence, reducing how often you need to look at your phone. That's a direct answer to the Whoop/Oura screenless trend Gurman flagged in the same newsletter.
Credibility: Single-outlet aggregation with no named primary source. Treat as medium-confidence; the camera-equipped AirPods concept has circulated on Apple patent filings for 18+ months, lending some structural plausibility.
Corroboration check
| Claim | Sources | Confidence |
|---|---|---|
| watchOS 27: stability focus, AI coaching delayed | Gurman (Bloomberg, May 24) | High — single sourced but Gurman tier |
| iOS 27: AirPods settings, Genmoji quality, AirPlay DMA, dark Siri | Gurman (Bloomberg, May 24), MacRumors | High |
| iPhone 18 Pro C2 modem / 5G NR-NTN satellite | 9to5Mac (May 21), Forbes (May 24), multiple forums since Feb 2026 | Medium-high |
| AirPods Ultra with cameras / H3 / gestures | Cult of Mac aggregation (May 24) | Medium — no named primary insider |
What to watch next
- WWDC June 8: The watchOS 27, iOS 27, and macOS 27 keynote will confirm or contradict every item above. The AirPlay DMA item in particular may be announced quietly.
- iOS 27 beta: developer beta drops immediately after the June 8 keynote. Code strings in the beta will be the first hard evidence for the AirPlay default toggle.
- AirPods Ultra timing: no FCC filings or supply chain movement yet. September window is plausible but thin.
- Apple Watch Ultra 4 redesign (Digitimes, May 21, reported in prior digest): still no new corroboration. Hold at medium confidence.
