Apple's new Ultra 4 keeps the same design as Ultra 3 but adds a new S11 chip, doubles RAM to 4GB, and introduces a redesigned Health Sensing System with upgraded heart rate and HRV tracking. New features include high-frequency background heart rate monitoring, a heart rate watch face complication, more frequent HRV readings, a new Recovery HRV metric, and more accurate real-time step tracking.
Apple published a detailed study comparing the heart rate sensing of its new Health Sensing System in Apple Watch Series 12 and Ultra 4 against rivals like Garmin, Google Pixel Watch, Huawei, Samsung, WHOOP, and Oura Ring. The test involved over 1,400 participants across five sites in the US and Malaysia, using a Polar H10 chest strap as the accuracy benchmark during activities like running, cycling, HIIT, and daily tasks.
Apple unveiled the Apple Watch Series 12 and Apple Watch Ultra 4 at its Sept. 9 event, both running WatchOS 27 with features that work independently of a paired iPhone. Unlike this year's iPhones, which saw price increases, both watches kept their previous starting prices—$400 for the Series 12 and $800 for the Ultra 4—with preorders open now and shipping Sept. 18.
Insta360 has released the Luna Pro, a pared-down version of its Luna Ultra steadycam that removes the telephoto lens but keeps the same 1-inch 8K sensor. The standout feature is the ability to record 4K vertical video at 30fps, something the pricier Ultra model currently lacks. It costs $599.99 and, unlike DJI's Osmo Pocket 4, is actually sold in the US market.
Lenovo's Legion 9i Gen 10 pairs a 24-core Intel Core Ultra 9 290HX Plus with an RTX 5080 GPU capable of drawing up to 175W, 64GB of DDR5-4800 memory, a 2TB Gen 5 SSD, and a nearly 100Wh battery. The reviewer calls it the best laptop they've tested, noting it performs almost identically to a desktop PC despite weighing 7.7 pounds and requiring a bulky 400W charger.
A comparison of the flagship-sized iPhone 18 Pro Max and Galaxy S26 Ultra shows both share a 6.9-inch screen but differ in build: Apple mixes aluminum and glass while Samsung uses an all-glass back. Samsung's phone is lighter and thinner, has a marginally higher-resolution AMOLED display, and retains the S Pen stylus, while Apple's OLED screen edges ahead on peak brightness at 3,000 nits versus 2,600 nits.
Apple's new iPhone 18 Pro Max debuted at $1,299, a $100 jump from last year's model, putting its 256GB version near the price of Samsung's $1,300 Galaxy S26 Ultra. The two flagships now compete closely on battery life and cameras, despite differing designs: the 18 Pro Max uses an aluminum unibody with a 6.8-inch OLED screen, while the lighter S26 Ultra features a 6.9-inch AMOLED display with a unique Privacy Display mode.
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's newly announced AirPods 5, Apple Watch Series 12, and Apple Watch Ultra 4 are now listed for pre-order on Amazon ahead of their September 18 release. The AirPods 5 lineup adds Active Noise Cancellation across both models starting at $129, while the Watch Series 12 and Ultra 4 introduce a new Health Sensing System with higher-frequency heart rate and HRV tracking, a readiness score, and audio features like Live Rewind and Siri Recap. New band colors, including translucent Ocean Band options, are also available starting at $99.
Apple's new AirPods 5 are available for pre-order at $129 and $149, while retailers are already discounting the newly launched Apple Watch Series 12 and Ultra 4 by up to $325. Separately, the entry-level M5 MacBook Air is selling for $1,099 through Apple's refurbished store, $200 under its regular price.
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.
