In particular, the operation of the camera stabilization system
The authors of iFixit decided to use an unusual way to beat their typical disassembly of the next iPhone. When disassembling the iPhone 15, they used a microscope.
Thanks to this solution, we can examine in detail the Taptic Engine module, the adhesive that holds the battery, the camera with its optical stabilization system, and much more.
By the way, the video allows you to clearly see that the iPhone 15 and iPhone 15 Pro Max use different 48-megapixel image sensors. The second has a larger sensor.
