At its hardware event in September, Apple unveiled the much-anticipated next-generation smartwatch – the Apple Watch Series 4. From a larger display to a built-in electric heart sensor that can measure a variety of health metrics, it does latest device with some noteworthy new features.
Find everything you need to know about the Apple Watch Series 4.
The ECG feature of the Apple Watch Series 4
One of the headline features of the Apple Watch Series 4 is the ability to perform an electrocardiogram (ECG) measurement of your heart's electrical impulses to your heart health to measure and give a vague baseline for your overall well-being. It was approved by the US Food and Drug Administration, but was not ready for publication. But it is now, and owners of the Apple Watch Series 4 can update their cell phones and give the function a fuss. It is easy to use. Just open the app on your Apple Watch Series 4 and hold your finger on the Digital Crown until the measurement is complete.
Design and Display
The Apple Watch Series 4 is available in two sizes ̵
The respite app that many use for meditation or for Lowering their heart rate will now be available as a dial. That way, you can use it by simply lifting your wrist so that the Breathe app can guide you through deep breaths.
The Series 4 looks largely similar to its predecessors, though there's a new digital version of the Crown with haptic feedback. This gives you a better feeling as you flip through items on your watch. The speaker has also been completely redesigned, making it 50 percent louder. The microphone is now on the opposite side – far away from the speaker. This will hopefully help to reduce the echo and make the phone call clearer.
The back of the Series 4 is made of black ceramic and sapphire crystal so that radio waves can pass through the front and back. According to Apple, this should improve the reception of cells.
Specifications and Battery
Under the hood is Apple's next-generation S4-64-bit dual-core processor, which works twice as fast. Accelerometer and gyroscope have twice the dynamic range and can scan motion data eight times faster.
However, the battery life has not changed – the Apple Watch Series 4 has the same battery life of 18 hours. Outdoors, Apple has increased outdoor exercise time to six hours, and full GPS tracking for long bike rides.
Software and special health features
The Apple Watch Series 4 runs on Apple's new WatchOS 5 operating system. It brings a number of improvements, including improved fitness and health tracking, walkie-talkie mode and more.
The Series 4 also offers a lot of additional health features. For starters, it can now recognize when you fall by analyzing the trajectory of the wrist and the impact acceleration. It will then trigger an emergency call. If you find you are immobile for 1 minute, your emergency call will be automatically called with the SOS feature and sent to your emergency contacts.
While older models of the Apple Watch include an optical heart rate sensor to track burnt calories, resting heart rate, and more, the Series 4 offers some new features. You will now receive a notification if your heart rate seems too low – which could result in your heart not pumping enough blood into the body.
Also, the Apple Watch can now shield your heart rhythm in the background. It sends a notification to the clock when an irregular rhythm is detected that may indicate atrial fibrillation. While the device can not diagnose the problem, it can detect it for you, so you can see a doctor.
One of the most impressive features of the Series 4 is possibly the built-in electric heart sensor. Integrated into the back of the sapphire crystal and the digital crown, users can now create an electrocardiogram (ECG) – the first of its kind in a smartwatch. This measures the electrical activity of the heartbeat to help diagnose heart disease and other conditions. You can take an ECG directly from your wrist anytime, anywhere by opening the app and placing your finger on the digital crown. Since all information is stored in the health app, you can share the ECG with a doctor who can see a more detailed picture of what is happening. Apple has also received approval from the Food and Drug Administration.
Price and Availability
The Apple Watch Series 4 is available now and costs $ 399, while the mobile model starts at $ 499.
