The Apple Watch Series 4, released in September 2018, marked a major redesign and upgrade compared to the Series 3. Here are the key features and improvements of the Apple Watch Series 4:
Key Features:
1.Larger Display:
•The Series 4 introduced a larger, edge-to-edge display with thinner bezels. It came in two new sizes: 40mm and 44mm (up from 38mm and 42mm in previous models).
•The screen area was 30% larger than its predecessor, offering more room for apps, notifications, and watch faces.
2.New Design:
•Along with the larger display, the Series 4 had a slightly slimmer profile, making it sleeker and more modern in appearance.
3.ECG (Electrocardiogram) Feature:
•One of the most notable new health features was the ability to take an ECG directly from the wrist. This allowed users to monitor their heart rhythm for irregularities like atrial fibrillation (AFib), providing potentially life-saving health data.
•The ECG app received FDA clearance in the U.S. and similar certifications in other regions.
4.Fall Detection:
•Another important feature was fall detection, which could detect when a user took a hard fall and automatically contact emergency services if the user didn’t respond within a minute.
5.S4 Chip:
•Powered by the new S4 chip, the Apple Watch Series 4 had improved performance, making it significantly faster and more responsive than earlier models.
6.Improved Heart Rate Sensor:
•In addition to the ECG, the optical heart rate sensor was enhanced, providing more accurate heart rate monitoring.
7.Digital Crown with Haptic Feedback:
•The Digital Crown was redesigned to include haptic feedback, giving users a more tactile experience when scrolling or interacting with the watch.
8.New Speaker:
•The speaker was made 50% louder, improving call quality, Siri interaction, and other audio-based features.
9.Fitness and Health Tracking:
•Series 4 continued Apple’s emphasis on health and fitness, offering advanced workout tracking, automatic workout detection, activity rings, and more. It also included features like guided breathing, mindfulness, and emergency SOS.
10.watchOS:
•Series 4 shipped with watchOS 5 and received several updates to watchOS versions, enhancing its capabilities. However, support for newer updates might eventually become limited as newer models are released.
11.Battery Life:
•Battery life remained similar to previous models, with up to 18 hours of typical use.
Discontinuation:
•Apple officially discontinued the Series 4 in September 2019 with the release of the Apple Watch Series 5, although the Series 4 remains highly regarded for its balance of design and features.
