Generally, I like the health and fitness watch face because I am a fitness freak guy. 🙂 So it is easy to navigate the health and fitness apps because it creates shortcuts of the apps on your watch face.

Also, you can do many things with the watch faces because every part of the UI has been re-designed and more familiar. Apple has created new complications of UI, so you get every information in detail like photos, maps, calendars, fitness apps, etc.

I think you’re going to love everything about the new displays on series 4.

Overall Design has improved

As Apple watch S4 has two models: The basic model is 40mm x 34mm, while the extended model is 44mm x 38mm. Nonetheless, the bezels around the display have reduced, S4 has not improved overall size.

Series 4 speaker and micHere mic and speaker both are opposite sides. Speaker is 50 % louder than the previous watch which is surpassing for phone calls, walkie-talkie, and Siri requests. The mic is moved to the counter side as far away from the speaker as possible to reduce the echo when you make the call.

The back side of the apple watch series made entirely of black ceramic and sapphire crystal. It’s highly functional radio waves can now pass through both the front and the back resulting in the improved cellular reception.

These Apple watch series(s) are quite expensive but you can buy the best cheap smartwatches for iPhone users.

Apple Watch Series 4: Performance and Sensors for your better experience

apple watch series 4 processor and chip performanceThe brain of Apple Watch series 4 built with 4th generation Silicon in Package(SIP) powerful new dual-core 64-bit processor and a new GPO both custom designed by Apple silicon team to deliver up to two times faster performance.

Apple Watch being a mini iPhone on your wrist, it has never felt like using one. Even simple apps would take a while to launch. It is difficult to notify any speed enhancements considering the Apple Watch Series 3 was already an excellent performer.

S4 Optical sensorEvery smartwatch such as Samsung, Fitbit, Google’s wear OS has the accelerometer and gyroscope to track all-day activity tracking or even identifying your swim stroke But, the Apple Watch Series 4 has a next-generation accelerometer and gyroscope with twice the dynamic range measuring up to 32

G-forces and can sample motion data eight times faster.

New Emergency Fall detection features

Series 4 detects a fall alongside measuring step tracking, heart-rate sensing, fitness tracking. When you fall while walking, or on a bike, it will automatically make a call 911 of your emergency list.

Is this feature really helpful and why?

Yes, This is a really meaningful feature but we hope you never need in the future. But, You should know about it.

After the studies and getting tremendous data from the thousands of people, one of the teams of the apple has figured out that the Fall is a repeatable motion pattern that happens.

With a new accelerometer and gyroscope, the watch analyzes risk, trajectory and impact acceleration to determine the fall occurs. After detecting a fall, Series 4 reads an alert and from that alert, you can initiate an emergency call also, it sends a message with your locations to your emergency contacts using the SOS feature that has already built into Apple watch.

Optical Heart rate sensor – Proactive Health Monitor

The optical heart sensor has been essential to Apple watch from the beginning. It allows us to calculate the calorie burn during your workouts. Also, it tracks your heart rate when you are resting, or you are working.

But what is new in this Apple Watch Serie 4?

The rear heart-rate sensor has been completely redesigned this time around, with a lot of heart rate potential.

apple-watch-series Heart rateThere is three type of heart rate sensor:

  1. You will get a notification if your heart rate appears to be too low.
  2. The second feature is related to heart rhythm. (The watch keep tracking your heart rhythm in the background. It sends an alert if it detects an unnatural rhythm that appears to be atrial fibrillation. It won’t catch every occurrence of AFib. But this is a pretty useful feature, and it will help people a lot.)

These two feature powered by the optical sensor, the third is made by electrical heart sensor.

3. ECG: there are electrodes placed into the back of sapphire crystal and the digital crown that allows you to take an Electrocardiogram.

apple-watch-series 4 Heart rate - ECG

This is the first ECG (Electrocardiogram) product that directly provided to customers by Apple.

How ECG works in Series 4?

You will have to open the app and put your finger on the digital crown.

The built-in electrodes placed in the back crystal in the digital crown detects electrical impulses from your heartbeat. At here the S4 chip will be activated which converts electrical impulses to signal. The entire process takes just 30 seconds.

After this moment, you will receive a heart rhythm classification if your heart is beating in a normal rhythm. The app will analyze the measurement as sinus rhythm and the app will also analyze atrial fibrillation. It records their classifications as the symptoms in the form of ECG graph. And these data will be stored in the health app as a PDF so you can share it with your doctor.

For this thing, Apple has received clearance from the FDA.

And I believe this is one of the Best Heart rate monitors.

Apple Watch Series 4 Review: Battery

The Apple Watch has always been a “charge it every day” device. The outdoor workout time has been increased to six hours so you can have full GPS tracking which is perfect for those marathons or long bike rides.

S4’s battery life has a limitation that Apple hasn’t solved yet. Qualcomm is encouraging longer smartwatch battery life, which runs more days (weeks), not days.

We’ll be testing full battery life soon.
