The Xiaomi Mi Mix 2 has been torn down by Chinese site ZOL and well be taking a look at some of its inner workings. The teardown has revealed several improvements in design and materials when compared to the original Xiaomi Mi Mix.
There are no screws to access the inside of the phone, so to get inside, the rear ceramimic panel of the phone must be heated to loosen its adhesive. Once the back panel comes off, the fingerprint scanners ribbon cable remains tethered to the board.
Theres a shield protecting the mainboard, which also features antennas printed in a gold color. The shield is otherwise plastic. While the Mi Mixs NFC antenna was all-over, the Mi Mix 2 moves it to only the rear of the phone. Likewise, the LED flash is built into this shield to ensure a solid contact. The new shield provides better shielding from electro-static.
Heres a side-by-side comparison of the Mi Mix and Mi Mix 2 with their back-covers and electromagnetic shielding removed.
Here are is a side-by-side of the Xiaomi Mi Mix and the Mix Mix 2s mainboards. While the Mi Mix 2s mainboard is smaller, its still quite spread out compared to other boards. Xiaomi had to keep the components spread out in a flatter and more spread-out way in order to keep the phones bezels to a minimum.
