Apple Watch Series 4, launched on September 12, 2018, is the fourth iteration of the Apple Watch. The Series 4 models are the first Apple Watches to feature a redesign since the Apple Watch was introduced 4 years ago in 2015.
According to the Apple design chief Jony Ive, the Apple Watch Series 4 is designed to inspire users to live a healthier, more energetic life, and with its LTE connectivity and new health characteristics, Apple’s wrist-worn gadget has become powerful enough to change the way you live.
Available in 40 and 44mm size options, Apple Watch Series 4 models feature displays up to 30% larger than preceding models. Despite the larger displays, which flow right into the casing thanks to curved corners, the Apple Watch framework has been slimmed down, so the Series 4 has a thinner, smaller case.
Despite the redesign, Apple Watch Series 4 models continue to work with all previous Apple Watch bands, both first and third party, as there have been no changes to the design of the lugs.
With the larger display, app content is even more easier to see than ever on the Series 4, and there are new complications and a wide range of new watch faces. There’s an Infograph face that supports eight complications, a Breathe face for swift access to the Breathe app and breathing relaxation techniques, and motion faces featuring Vapor, Liquid Metal, and Fire & Water, all of which interact distinctively with the display.
All Apple Watch Series 4 model features a black ceramic and sapphire crystal backing for the first time, allowing for better cellular service because radio waves can more easily pass through the front and back. The Digital Crown includes haptic feedback for what Apple says is a more mechanical, responsive feel when scrolling.
Apple Watch continues to be water resistant and suitable to use when swimming, it still supports Apple Pay, and it includes all of the health tracking traits available in all previous Apple Watch models, monitoring steps taken, calories burned, stairs climbed, and heart rate.
There’s a 50 percent louder speaker for use with Siri, phone calls, and Walkie-Talkie, and the microphone has been relocated to minimize echo. Inside, the Apple Watch features a quicker, more efficient S4 chip that offers 2x the speed, along with a W3 wireless chip.
Apple focuses heavily on health in the Series 4 Apple Watch models, introducing a new electrical heart rate sensor that, when combined with electrodes in the Digital Crown can take an electrocardiogram (ECG) reading using an ECG app.
The ECG feature can recognize atrial fibrillation, a heart condition that is an indicator of major health conditions, and all of the ECG readings can be effortlessly shared with a doctor. Sensors also regularly scan heart rhythms and the Apple Watch Series 4 can send a notification if an irregular heartbeat (aka atrial fibrillation) is noticed.
Apple has received FDA clearance in the U.S. for these advanced features, and ECG readings are limited to the United States, Hong Kong, and various countries in Europe at this time. Apple Watch Series 4 also features a next-generation optical sensor which sends notifications when your heart rate is too low or too high.
With a next-generation accelerometer and gyroscope, the Apple Watch Series 4 can discern if a fall occurs by analyzing wrist trajectory and impact acceleration. If the motion is not detected after a fall, the Apple Watch can initiate a call to emergency services and send a message to emergency contacts.
Even with all of the new characteristics, the Apple Watch Series 4 offers 18-hour “all day” battery life, and an expanded six-hour battery life for outdoor workouts. The battery life has been made workable through the S4 chip and LTPO display technology that offers better power efficiency.
Apple Watch Series 4 is available in Silver, Gold, and Space Gray Aluminum and Silver, Space Black, and Gold stainless steel, with the latter finish being an entirely new choice. There are no longer more expensive Edition models.
Apple is continuing to present both GPS and GPS + LTE models, but stainless steel models are all LTE only. Apple Watch Series 4 aluminum models are priced starting at $399 in the United States, while Aluminum GPS + LTE models are priced starting at $499. Stainless steel models are priced starting at $699.
Apple is selling the Apple Watch Series 4 models with a wide variety of bands at varying price points, and additional bands can be purchased on a standalone basis. There are also Nike and Hermès Apple Watch Series 4 models available with distinctive bands and watch faces.
