The iPhone 16 Pro Clear Case was released along with the iPhone 16 lineup in September 2024. Apple described the case as “Thin, light, and easy to grip — this Apple-designed case shows off the brilliant colored finish of iPhone 16 Pro while providing extra protection.”

Like the previous versions of Apple’s clear cases, this case uses multiple materials that are molded together to provide protection, grip, and access to buttons, using “a blend of optically clear polycarbonate and flexible materials.”

In addition, this case adds a new button that works “seamlessly with Camera Control. It features a sapphire crystal, coupled to a conductive layer to communicate finger movements to the Camera Control.” Camera Control was a new feature introduced with the iPhone 16 lineup that added one-button access to the camera and its controls using a touch-sensitive side-button. On the Clear Case, the Camera Control button is white (not clear) and made of a conductive material to allow full functionality of the iPhone button.

Like its predecessors, this case has “built-in magnets that align perfectly with iPhone…[offering] a magical attach experience and faster wireless charging, every time. When it’s time to charge, just leave the case on your iPhone and snap on your MagSafe charger.”

Apple also mentions that “all materials and coatings are optimized to prevent yellowing over time,” a claim that, in my experience, has stood the test of time. I first purchased Apple’s Clear Case with my iPhone 11 in September 2019 and it, along with the iPhone 12–15 cases, shows very little evidence of yellowing.

The Apple Watch Series 4 was the first major redesign of the Apple Watch family and added several important functions, including health-related features. The display was over 30% larger and filled the entire screen with curved corners, it added more advanced input capabilities, more powerful processing, and more advanced sensors. This model also included GPS and cellular service for use in the United States and Canada.

Like all cellular-capable Apple Watch Series 4 models, this watch could connect to the Internet without an iPhone and send and receive phone calls with an activated cellular service. It was controlled with a Digital Crown with haptic feedback and Force Touch.

This Apple Watch Series 4 model is 44 mm (previous Apple Watch models were 38 mm and 42 mm) with a 368×448 OLED screen. This stainless steel case model used a sapphire crystal to cover the display. All Series 4 models used a ceramic and sapphire crystal back to connect to the wireless charger.

The Apple Watch Series 4 shipped with “revolutionary health capabilities, including a new accelerometer and gyroscope, which are able to detect hard falls, and an electrical heart rate sensor that can take an electrocardiogram (ECG) using the new ECG app.” When announced on September 12, 2018, the ECG feature was not available until it was released on December 6, 2018, through an iOS update.

The ECG feature on Apple Watch Series 4 marked “the first direct-to-consumer product that enables customers to take an electrocardiogram right from their wrist, capturing heart rhythm in a moment when they experience symptoms like a rapid or skipped heart beat and helping to provide critical data to physicians. The irregular rhythm notification feature on Apple Watch can now also occasionally check heart rhythms in the background and send a notification if an irregular heart rhythm that appears to be atrial fibrillation (AFib) is identified.”

In addition, a new accelerometer and gyroscope could detect falls and automatically call 911.

There were 12 different options for this particular Apple Watch Series 4 model:
