The latest report from well-known Apple analyst Guo Mingxi shows that the newly designed Apple Watch Series 4 is expected to be launched this fall, and the screen size will increase by 15%. Although we didn't get more details, the model may mark the first design change since the Apple Watch debuted three years ago.
Guo Minghao expects the Apple Watch Series 4 to be 1.57 inches (39.9 mm) and 1.78 inches (45.2 mm) respectively, while the current Apple Watch is 38 mm and 42 mm, respectively. It's unclear whether the fuselage will be bigger, or by reducing the border to increase the screen size, but this does not prevent designers from sharing their own conceptual design.
Venya Geskin, who had been offering Apple's breaking news, created the model above, and he imagined displaying a larger screen on the new Apple Watch while preserving the existing physical size. In this design, the Apple Watch Series 4 screen has a rounded corner design and reduces the border to maximize the display area, which is similar to the iPhone X display screen.
Developer Ryan Jones calculated from rumors that the increase in screen size can increase the display area of the 38mm and 42mm models by 35% and 38%, respectively. Such changes will significantly enhance the user's interaction with the watch, enabling a larger dial display and virtual buttons, and the watch can display more text at the same time, reducing the scrolling of the digital crown. In addition, watchOS 5 promises to bring rich HTML content to Apple Watch devices, so larger screens will enhance the experience of browsing websites and interacting with them.
Depending on the industry source, the upcoming Apple Watch Series 4 may use a micro-LED screen that is lighter and thinner, improves color gamut, increases brightness and supports higher resolution. If micro-LEDs are used this year, it may make room for other hardware improvements.
Guo Mingxi said that the next generation of Apple Watch will have better health monitoring capabilities, including better heart rate. The analyst did not explain whether the improvements were based on software or hardware, but did not rule out the possibility of a combination of the two.
Apple Watch's heart rate sensors currently use fast-flashing green LEDs and light-sensitive photodiodes to continuously monitor heart rate during exercise and breathing. Not only that, but Apple Watch can also measure heart rate at different intervals in the background based on the user's activity level, at which point it will switch to infrared light.
Unlike some smart watches, Apple Watch is not yet configured to monitor your heart rate. This feature in Apple Watch Series 4 will be a welcome improvement, but it is not yet certain if it does not use a different sensor array than the current Apple Watch.
In addition, Guo Mingxi also believes that the Apple Watch Series 4 will use high-capacity batteries to improve the battery life. The new Apple Watch will also use solid-state buttons instead of physical mechanical buttons to provide tactile feedback to the user through the Taptic Engine, and such design changes may also provide additional space for larger batteries.
Another possibility that Apple is testing is an electrocardiogram (EKG) function that records the electrical activity of the heart by placing two fingers on either side of the Apple Watch. This feature will detect changes in skin electrical energy caused by the heartbeat rhythm and may reveal abnormalities in the heart.
If there are no surprises, we will see the Apple Watch Series 4 debut at the Apple Autumn New Product Launch in September, when we will get more news about this smart watch.
