Redesigned UI

The Apple Watch Series 4 comes with a redesigned Watch OS 5 which makes use of the updated hardware to deliver more features than ever before. Talking about hardware, the new Apple Watch Series 4 is powered by a fourth gen processing unit which Apple calls S4 which is made up of a 64-bit dual-core processor and a new GPU.

Fall Detection

The Apple Watch also includes a new accelerometer and gyroscope setup that unlocks a feature that hasn’t been seen in any smartwatch before. Thanks to the upgraded accelerometer and gyroscope, the new Apple Watch will be able to detect if the wearer falls down, delivering an alert and initiating an emergency call in case the wearer stays immobile for a minute.

Optical Heart Rate Sensor

The upgraded Apple Watch Series 4 also features an optical heart rate sensor that is capable of performing more functions, including a low heart rate notification and a notification of an irregular heart rhythm.

All you need to do is hold you finger on the crown for 30 seconds and the electrodes within will collect all the required data to deliver an accurate ECG report. The Apple Watch Series 4 is also capable of detecting atrial fibrillation, a feature which has also been approved by the FDA.

Privacy-Focused Approach

Talking about privacy, the new Apple Watch Series 4 will ensure that all your health and fitness data remains safe from prying eyes. According to the company, all the data collected by the smart watch is encrypted on the device and on the cloud, so you can rest assured that it won’t be misused. Apple made a big deal about privacy, without mentioning Google or any of its competitors, and the fact is that watchOS 5 does bring new features without compromising on the data security.

Even with all the new features, the Apple Watch Series 4 will be able to deliver the same 18 hour battery life as the previous generation, with an increased outdoor workout time of 6 hours.
