Apple Watch Series 6

From October 2020 until September 2021, the Apple Watch Series 6 served as the company’s top smartwatch model. It had an always-on, brighter display and a blood-oxygen sensor for the first time, and was available in titanium, stainless steel, and aluminum. The Apple Watch Series 7 replaced the smartwatch as an organizational replacement.


After its first release in 2015, the Apple Watch swiftly rose to the top spot among wearables, with Q2 2015 sales of 4.2 million units. Apple designated the first Apple Watch as “Series 0” when it unveiled the Apple Watch Series 2 later that year, along with an upgraded processor for the “Series 1” and a brand-new “Series 2” Watch.

Many things changed when Apple unveiled the Apple Watch Series 3 in 2017. The firm began to view the Watch more as a fitness tool than a fashion accessory, even though it was offered in aluminum, stainless steel, and ceramic variants. This Watch included a processor that was 70% quicker than its forerunner, more RAM, and 16GB of LTE cellular connection.

A year later, Apple Watch Series 4 was introduced, with a significant redesign with a screen that was 30% larger in both versions and a 50% faster CPU than the Series 3 model. Series 4 included the fall detection function, ECG capability, and second-generation heart rate monitor. Speakers and microphones were reconfigured to be louder and more helpful.

The Apple Watch Series 5 was a significant improvement over the Series 4 in 2019. Apple included a built-in compass, an Always-On display with an energy-efficient LTOP OLED screen, quadrupled the capacity to 32GB, and brought back the Edition tier with a ceramic model and a brand-new titanium version.

Apple unveiled the Apple Watch Series 6 in 2020. Along with additional health sensors, this Watch had a new S6 processor that was up to 20% quicker than its predecessor, a brighter Always-On display, a blood oxygen app, and an always-on altimeter.

Following the launch of the Apple Watch Series 7 in October 2021, the Series 6 device was formally dropped by Apple.

Blood Oxygen Sensor and App

Blood Oxygen Sensor and App

With a new function that simply detects the user’s blood oxygen saturation, Apple Watch Series 6 enhances the health capabilities of earlier Apple Watch models so that customers may better understand their overall fitness and wellness. The amount of oxygen transferred by red blood cells from the lungs to the rest of the body is known as oxygen saturation, or SpO2, which measures how well the body is distributing oxygenated blood.

The Blood Oxygen sensor uses four clusters of green, red, and infrared LEDs as well as the four photodiodes on the rear crystal of the Apple Watch to detect light reflected from blood, compensating for normal fluctuations in the skin and enhancing accuracy.

The Blood Oxygen app for Apple Watch then employs an innovative bespoke algorithm created specifically for measuring blood oxygen levels between 70 and 100 percent. When the user is passive, such as while sleeping, on-demand measures can be made while they are still, and background measurements are collected periodically. The user will be able to follow trends over time to observe how their blood oxygen level varies because all data will be readily available in the Health app.

Apple is collaborating with scientists on three health projects, one of which will employ the Apple Watch to examine the potential use of blood oxygen levels in medical applications in the future. This year, Apple will work with Anthem, the University of California, Irvine, and Anthem to investigate the potential benefits of long-term monitoring of blood oxygen levels and other physiological signals in the management and control of asthma.

Separately, to better understand how blood oxygen measurements and other Apple Watch metrics can aid in the management of heart failure, Apple will collaborate closely with researchers at the University Health Network’s Ted Rogers Centre for Heart Research and Peter Munk Cardiac Centre, two of the largest health research organizations in North America. Finally, researchers from the University of Washington School of Medicine and the Brotman Baty Institute for Precision Medicine will study how signals from Apple Watch applications, such as Heart Rate and Blood Oxygen, might act as early warning indicators of respiratory illnesses like influenza and COVID-19.

Apple Watch Series 6 special edition

Black Unity is a unique Watch edition that Apple designed for the Apple Watch Series 6 device. The publication was timed to coincide with Black History Month in February:

To further their goals of advancing equality and civil rights in the US and throughout the world, Apple is assisting six international organizations: International Institute on Race, Equality and Human Rights; Leadership Conference Education Fund; NAACP Legal Defense and Education Fund, Inc.; Souls Grown Deep; Black Lives Matter Support Fund through the Tides Foundation.

The 44mm model’s GPS and GPS + Cellular iterations were all out of stock in April. Later, Apple removed the Watch from its home website, however, the 40mm version of this wearable is still available here.

Apple Watch Series 6 Review

If you’re coming from an Apple Watch Series 3, we suggested upgrading in our video review of the Apple Watch Series 6:

“If you’re upgrading from an Apple Watch Series 3 or earlier, the decision is straightforward. You’ll receive a watch that is significantly quicker, a casing with a bigger display, better speakers, and a microphone, among many other things. Additionally, you’ll be able to benefit from all of the fantastic new improvements that watchOS 7 and the next watchOS updates will provide. If you’re coming from an Apple Watch Series 1, 2, or 3, I think it’s a no-brainer to upgrade to either a SE or Series 6.“

Design and Performance

Design and Performance

Through new hardware that fits even more features and power into the same enviably compact design, Apple Watch Series 6 enhances performance. The updated S6 SiP runs up to 20% quicker thanks to a new dual-core processor based on the A13 Bionic in the iPhone 11, enabling apps to start 20% faster while preserving the same all-day 18-hour battery life. 2 The U1 processor and Ultra Wideband antennas3 are further capabilities of the Apple Watch Series 6 that enable short-range wireless location to support novel experiences like next-generation digital vehicle keys. Apple Watch Series 6 offers enhanced battery life for monitoring some exercises, such as indoor and outdoor runs, and quicker charging, with a full charge taking less than 1.5 hours.

When the user’s wrist is down outside, the improved Always-On Retina display on the Apple Watch Series 6 is up to 2.5 times brighter than the Apple Watch Series 5 display, making it considerably simpler to read the watch face in direct sunshine. The user may now access Notification Center and Control Center when their wrist is down, touch on complications, and slide to switch faces without waking their watch screen.
