The Apple Watch Series 4 is a smartwatch that was designed, manufactured, and sold by Apple from 2018 to 2019 as part of the Apple Watch series. The Watch Series 4 has been introduced on September 12, 2018, and its price started at $399.
All-New Watch comes in two new sizes 40 mm and 44 mm and has been made in 6 different finishes including Aluminum (Silver, Space Gray, Gold), and Stainless Steel (Silver, Space Black, Gold).
The device features a 1.57-inch or 1.78-inch LTPO OLED Retina Displays with Force Touch covered by Ion-X glass or Sapphire crystal, Dual-Core Apple S4 processor, 1GB of RAM, Apple W3 chip, 16 GB of flash memory, Taptic Engine, Digital Crown, NFC for Apple Pay, GPS, Bluetooth 5.0, ambient light sensor, ECG based on electrical heart sensor, heart rate sensor, accelerometer, a gyroscope, water-resistance up to 50 meters, wireless charging, and additional Cellular model.
The Apple Watch Series 4 features the Apple S4 dual-core processor, which Apple claims can deliver double the S3’s performance. It also features 16GB of storage, a larger display compared to the Series 3, and a new electrical heart sensor that measures the potential difference between the wrist and a finger from the opposing hand into the S4 Module over 30 seconds.
The ECG system has received clearance from the United States Food and Drug Administration, a first-ever for consumer device, and is supported by the American Heart Association.
This device can also detect falls and will automatically contact emergency services unless the user cancels the outgoing call. The microphone was moved to the opposite side between the side button and the digital crown to improve call quality.
Other changes include the digital crown incorporating haptic feedback with the Apple Haptic Engine and includes the new Apple-designed W3 wireless chip.
This Watch has been discontinued on September 10, 2019, and has been replaced by Apple Watch Series 5.
Today Apple Watch Series 4 is 6 years old!
