A study covered by The Conversation had 58 adults cycle while wearing devices from Apple, Samsung, Garmin, and Fitbit alongside a metabolic analyzer that measures actual gas exchange to determine calorie burn. Comparing the watches' estimates to that gold-standard measurement, researchers found substantial inaccuracies, with errors reaching 100% or more in some cases, particularly among people with higher body fat percentages.
In China, smartwatches designed for children have become a preferred device for parents managing preteens, offering location tracking and communication features without giving kids full smartphone access. These wearables let parents keep tabs on their children's whereabouts while limiting exposure to broader internet content and social apps.
Android Authority's Paul Jones argues that despite the $350 Moto Watch Ultra's strong feature set—LTE eSIM, Wear OS 6, a 1.5-inch pOLED screen and Polar health tracking—its weaker processor and limited two-generation OS upgrade path make it a risky buy. Instead, he recommends five alternatives including the Samsung Galaxy Watch Ultra (2025), Google Pixel Watch 4, Samsung Galaxy Watch 9, Garmin Venu 4 and Amazfit Balance 2. The Galaxy Watch Ultra 2025, now around $330 on Amazon, is highlighted as the top pick for Samsung phone owners thanks to its rugged sapphire-glass build, 64GB storage, multi-day battery and four years of promised software updates.
Counterpoint Research reports that worldwide smartwatch shipments declined 4% year-over-year in the second quarter of 2026, as consumers kept existing devices longer rather than upgrading. Huawei topped the market in total shipments, while Apple posted the strongest growth rate among the five leading brands. Counterpoint projects only 1% shipment growth for the full year.
Amazon has discounted the recently released Garmin Vivoactive 6 fitness smartwatch by 23% off its list price, marking the lowest price the device has seen since launch. The deal applies to Garmin's latest wearable, which tracks fitness and health metrics.
Researchers are increasingly using wearable devices—smartwatches, wristbands, patches and rings—to collect real-time physiological data such as heart rate, blood pressure and activity in clinical trials. Specialists say advances in sensor technology and AI could enable decentralized trials where participants are monitored remotely, with dosing personalized to individual data rather than fixed protocols. Current devices already track metrics via accelerometers, gyroscopes and photoplethysmography, with future versions potentially measuring biomarkers like glutamate and cortisol.
Amazon is offering a 25% discount on the Samsung Galaxy Watch 8 Classic's 46mm LTE model, lowering the cost of Samsung's premium smartwatch. The deal brings the flagship wearable down to a more accessible price point for shoppers considering a cellular-enabled smartwatch.
Apple has launched the Watch Series 12, a modest refresh of last year's Series 11 that keeps the same $399 starting price but adds a new ceramic case option alongside aluminum and titanium. Alongside it, Apple introduced the cheaper Watch SE 3, starting at $249, which trades some display and material upgrades for a lower cost.
Amazon is currently selling Samsung's new Galaxy Watch Ultra 2 for $699.99, and buyers who purchase it now receive a complimentary $100 Amazon gift card. The promotion effectively lowers the cost of acquiring the rugged smartwatch through the retailer.
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.
Apple has released the Apple Watch Ultra 4, its premium smartwatch that inherits the updated internal components from the Apple Watch Series 12 while extending battery life further. The device places renewed emphasis on heart health monitoring alongside the rugged, high-performance design Ultra buyers expect.
Counterpoint Research's Q2 2026 report found global smartwatch shipments fell 4% year over year, even as Apple, Huawei and Garmin posted gains. Apple grew 14% to capture a 20.1% share, trailing only Huawei's 21.8% share, with the Watch Series 11 and Watch SE 3 driving over 80% of Apple's volume. Huawei's growth was concentrated in China, which made up about 80% of its shipments.
