The Moto Razr 2022 looks more modern without the chin, but it actually served an important purpose on the Razr 5G (beyond nostalgia). A spring mechanism inside the chin held the foldable display taut to try to minimize creasing. The 2022 model takes a different approach.
The disassembly video of Weki Home offers a great visual demonstration of how the two different mechanisms work. Start at minute 9, you can see the display of the old Razr 5G move slightly up and down as the phone is opened and closed.
The new Moto Razr 2022 keeps the display fixed at both ends and instead folds the central part into a teardrop shape (with a diameter of 3.3 mm). There are thin metal strips in the center, which help reduce stress on the display. As you can see below, the folded area on the new model is noticeably smaller.
Some other interesting things to note. Everything is stacked in multiple layers interconnected by ribbon cables, this requires real skill to disassemble and reassemble. Plus, that colorful sheen you see on PCBs is the conformal coating that repels any water that may have entered the phone.
A closer look at the Moto Razr 2022 hinge mechanism • The two battery cells
As is typical with foldables, the battery is split into two cells: a small 712mAh / 2.8Wh in the top half and a larger 2,788mAh / 10.9Wh in the bottom half. Motorola didn’t use vapor chambers to cool the Snapdragon 8+ Gen 1 chipset, instead relying on a copper block, several copper sheets, and thermal paste to do the job.
Motorola yesterday only announced details for the launch in China, but insiders and analysts say the Moto Razr 2022 is set for a global rollout (like its predecessors).
