Charge times are from 0–80% and 0–100% using the included Apple Watch Magnetic Fast Charging USB-C Cable. Testing conducted by Apple in August 2022 using preproduction Apple Watch Series 8 (GPS) and Apple Watch Series 8 (GPS + Cellular), each paired with an iPhone; all devices tested with prerelease software, Apple Watch Magnetic Fast Charging USB-C Cable (Model A2515), and Apple 20W USB-C Power Adapter (Model A2305). Charge time varies with region, settings, and environmental factors; actual results will vary. The ECG app and irregular rhythm notification require the latest version of watchOS and iOS, and are not intended for use by people under 22 years old. The ECG app is available on Apple Watch Series 4 or later (not including Apple Watch SE). The irregular rhythm notification is not designed for people who have been previously diagnosed with AF. Flanking the improved screen are the usual selection of buttons: the Digital Crown for navigation and a secondary, side button. The Digital Crown now has haptic responses when you twist it, slightly bumping your finger with a subtle vibration. As with so many design tweaks here, it seems small at first but the result is terrific. The resistance offered when you’re scrolling through menus, or jumping between options in the Workout app, adds that tangible feeling so often missing from techy watches.

There’s been little change in the design of the Apple Watch since its introduction – until now. The Series 4 is the first real reinvention of the wearable. I say reinvention, but if you’re familiar with previous Apple Watches then you’ll instantly feel at home with the Apple Watch Series 4. It’s a tremendous idea and one that could save someone’s life. It’s not, however, something that can be triggered by pretending to fall or even being pushed over. Trust me, I’ve tried. Requires Apple Watch Series 7, SE, Ultra, or later. For a list of supported countries and regions, see apple.com/watchos/feature-availability. I have replaced an original screen from another apple watch and everything seems to have gone well. But when I try to pair with the iphone it doesn't succeed. Is it because I didn't put the NFC chip from the original apple watch? What can be?. All models of the Apple Watch Series 4 remain water-resistant to 50m and will survive a dunk in sea water, too. These models use the same water-ejection method as the Series 2 and Series 3, where it will play a specific tone to eject water from the speaker. Screen and speaker

The Apple Watch 4 is still one of the top smartwatches

Charge times are from 0–80% and 0–100% using the included Apple Watch Magnetic Fast Charging USB‑C Cable. Testing conducted by Apple in August 2022 using pre‑production Apple Watch Series 8 (GPS) and Apple Watch Series 8 (GPS + Cellular), each paired with an iPhone; all devices tested with pre‑release software, Apple Watch Magnetic Fast Charging USB‑C Cable (Model A2515) and Apple 20W USB‑C Power Adapter (Model A2305). Charge time varies with region, settings and environmental factors; actual results will vary.

Apple Watch Series 1 has a water resistance rating of IPX7 under IEC standard 60529. Apple Watch Series 1 is splash and water resistant, but submerging it is not recommended. If you reside in the U.S. territories, please call Goldman Sachs at 877-255-5923 with questions about Apple Card.LTE calling depletes the battery faster than hammering the GPS. This reaffirms the point that this is purely meant as an addition to your phone, rather than a futuristic wrist-based replacement for it. Make sure to update your Apple Watch to watchOS 5 or later (and the paired iPhone to iOS 12 or later) to avoid pairing issues after a display replacement. Charge times are from 0–80% and 0–100% using the included Apple Watch Magnetic Fast Charging USB-C Cable. Testing conducted by Apple in August 2023 using preproduction Apple Watch Ultra 2 (GPS + Cellular) paired with an iPhone; all devices tested with prerelease software, Apple Watch Magnetic Fast Charging USB-C Cable (Model A2515), and Apple 20W USB-C Power Adapter (Model A2305). Charge time varies with region, settings, and environmental factors; actual results will vary.

Released alongside the Apple Watch 4, watchOS 5 brings a handful of software updates and tweaks to all the previous Apple Watch models (aside from the very first version, often dubbed Series 0). Being able to stream music directly to the watch and take any incoming calls means you can head out for a 10km run with just your watch and some AirPods. When you’re running you’ll also get heart rate data – again this data was comparable to both the older Apple Watch 3 and a Fitbit Charge 2 I was using as a comparison. Perhaps the most important new feature here is the FDA-approved electrode-based heart rate monitoring. When the ECG app arrives later this year, you'll be able to put your finger on the digital crown for 30 seconds to receive an ECG reading that you can export to PDF to share with your doctor. Since this feature isn't yet available, we didn't test it, but we'll update this review with our findings as soon as it comes out. Charge times are from 0–80% and 0–100% using the included Apple Watch Magnetic Fast Charging USB‑C Cable. Testing conducted by Apple in August 2023 using pre-production Apple Watch Series 9 (GPS) and Apple Watch Series 9 (GPS + Cellular), each paired with an iPhone; all devices tested with pre-release software, Apple Watch Magnetic Fast Charging USB‑C Cable (Model A2515) and Apple 20W USB‑C Power Adapter (Model A2305). Charge time varies with region, settings and environmental factors; actual results will vary.As far as smartwatch app ecosystems go, Apple's remains the most extensive by far. While it's still missing some key players like Spotify, you can find apps like American Airlines, Citymapper, Delta, Lyft, Neato Robotics, Philips Hue, Strave, and Uber, among many, many others. Comparatively, the apps available for Google wearOS, Fitbit OS, and Samsung Tizen watches are fewer in number and vary in quality. WearOS has the largest offering of the three, but actually getting them onto your watch isn't nearly as simple as it should be. It's easier on Samsung's Tizen watches, which include some apps Apple misses like Spotify and Speedo. Fitbit's offerings are the least developed of the bunch, but includes some big names like Deezer and Pandora.
