Apple's new $799 Watch Ultra 4 pairs a redesigned sensor array—32 electrodes arranged like flower petals—with the new S11 chip, enabling heart-rate readings every 5 seconds and HRV checks every 5 minutes, far more frequent than prior models. That increased sampling powers a new Readiness score that updates throughout the day rather than relying mainly on overnight data, plus a Daytime toggle in the Vitals app to view daytime alongside nighttime metrics.
Apple has launched the Watch Series 12 with faster charging but the same 24-hour battery life, alongside the Ultra 4, which extends battery life to 50 hours. Both models run watchOS 27, which brings tighter Siri and Apple Intelligence integration, including AI-suggested apps, new one-handed gestures, expanded workout and women's health tracking, and a Siri Recap feature for real-time transcription and translation.
Data from Xcode 27 reveals that Apple's new Watch Ultra 4 and Series 12 both ship with 4GB of RAM, twice the 2GB found in last year's Ultra 3 and Series 11. Apple did not disclose this memory increase in its official announcements, and the discovery came from developer tools rather than Apple's own specs pages.
Insta360's new Luna Pro shares most hardware with the flagship Luna Ultra, including the same Leica Summicron 20mm f1.8 lens, 1-inch sensor, 8K/30 and 4K/120 capture, Dolby Vision, 10-bit I-Log and 37MP stills, but uses a smaller single-lens gimbal head that trims about half an inch off the device's height. Storage (47GB expandable), battery (1,550mAh) and the detachable front panel remote/mic carry over unchanged from the Ultra.
Google's storage warnings push many users toward paid upgrades, but much of the used space in Gmail, Drive, and Photos can be reclaimed by clearing out large attachments, duplicate files, and unnecessary backups. A few targeted cleanup steps can free up meaningful space across the shared 15GB storage pool in minutes.
Apple's iPhone 18 Pro Max claims 45 hours of video playback versus 39 hours on the iPhone 17 Pro Max, along with faster wired and wireless charging. Aside from battery improvements, a variable aperture camera, larger vapor chamber and A20 Pro chip, the new model is nearly identical to its predecessor, and costs just $100 more starting at $1,299 for 256GB.
Apple introduced the Watch Series 12 and Watch Ultra 4 at its Cupertino event, keeping hardware largely unchanged but adding new 'Audio Intelligence' software features. These include Live Rewind, which replays the last 15 seconds of conversation as text, and Siri Recap, which uses ambient listening to summarize meetings or conversations into notes in a new Siri app. A Sound Recognition tool for detecting sirens, alarms and crying babies also debuts, alongside an upgraded health-sensing system with more frequent heart-rate tracking.
Apple unveiled the Watch Ultra 4, its top-tier smartwatch, featuring an S11 chip, upgraded heart-rate sensors, and battery life reaching 84 hours in low-power mode or 50 hours in normal use. The device introduces a daily readiness score, a VO2 Max test, and an AI-powered insights tab in the redesigned Health app, plus audio intelligence features for environmental sound alerts and conversation tracking.
Apple confirmed watchOS 27 will launch on September 14, bringing a dedicated Siri app with a more capable, synced assistant to Apple Watch. The update also reworks the Digital Crown into a dynamic app grid, drops Walkie-Talkie, and adds a unified Find My app plus expanded Smart Stack and Workout Buddy features. The update runs on Apple Watch Series 9 and later, Ultra 2 and later, and the new SE 3.
Apple unveiled the iPhone 18 Pro with a 48-megapixel main camera featuring variable aperture, using six laser-cut polymer blades that automatically adjust to let in up to 50% more light in dark settings. The phone also gains new Pro Controls for manual white balance, histogram exposure checks, shutter speed and skin texture adjustments, plus AI-driven smart focus tracking and upgraded video features like 60fps cinematic mode and 4K Dolby Vision time-lapse.
Apple unveiled the AirPods 5, an update to its entry-level earbuds line featuring a redesigned acoustic architecture that delivers 50 percent better noise reduction than the AirPods 4. The lineup keeps the same two-tier pricing structure: $129 without a wireless charging case and $149 with one, both arriving September 18.
Apple unveiled the Apple Watch Series 12 and Ultra 4, both built around a redesigned health-tracking system that checks heart rate every five seconds and HRV every five minutes, which Apple calls its most accurate wearable heart sensor yet. The watches also debut Audio Intelligence, featuring sound recognition, a 15-second 'live rewind' transcription tool, and Siri-generated meeting recaps, all powered by Apple's new S11 chip.
