Based on previous experience, we first removed the SIM card tray to avoid damage to the body during the disassembly process.

Like other Xiaomi phones, the Xiaomi Mi Max 2 uses two 0.8 mm x 25 mm screws to secure the back cover to the middle frame.

After removing two 0.8 x 25mm screws, open the back cover a little bit with a suction cup.

Insert a pick between the back cover and the body, and then slowly slide the pick to release the clips on the middle frame.
It is worth mentioning that the back cover of the Xiaomi Mi Max 2 is very easy to remove. I have never seen a phone back cover that can be taken off so easily.

When separating the rear cover from the body, it should be noted that the fingerprint module cable is still connected to the motherboard.
Disconnect the fingerprint module cable from the motherboard with a pry tool.

We found a chip marked with “5001 8500 1649” on the back of the fingerprint cable, but we can not determine its manufacturer. If you have any information, please let us know.

The Xiaomi Mi Max 2 features a classic three-stage design. The upper is the motherboard. The middle is the battery. The bottom is the USB board.

Before removing the motherboard, we need to remove the graphite sticker covering the metal plate and the battery.

Remove all the screws securing the metal plate and motherboard.

Remove the metal plate with tweezers.

The Xiaomi Mi Max 2 uses a large metal plate to secure the connectors to the motherboard.

Disconnect the battery connector from the motherboard. Then, disconnect the display cable, power button cable, FPC cable, touch cable, and coaxial cable from the motherboard.

Remove the front camera.

All the metal shields are welded to the motherboard, and one of the shields has a graphite sticker. According to experience, it should have a Snapdragon 625 processor and memory underneath. As with most midrange phones, the integration is not particularly high, whether it’s the motherboard or the sub-board.

The front camera module is relatively small. It comes from QTech, and the model number is F5E8YAR. However, we were unable to find this product on the QTech official website.

On the main camera, it is marked with A12N06P. It should also come from QTech.

The touch chip is from FocalTech, the model number is FT5446DQS.

Remove all screws securing the loudspeaker and the bottom board.

Surprisingly, after removing all the screws, the loudspeaker popped out automatically. Usually, it was glued to the chassis.

The sub-board is manufactured by Taiwan COMPEQ. It integrates a USB port and many metal contacts.

There are two adhesive tapes under the battery, and the battery can be removed by pulling out the adhesive tape.

The Xiaomi Mi Max 2 has a 5300mAh Li-ion polymer battery with part number BM50. It is manufactured by Sunwoda Electronics.
