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

Like other Xiaomi phones, Xiaomi Mi Max 2 is also using two 0.8*25mm screws securing the back cover to the middle frame.

After removing two 0.8*25mm screws, open the back cover a little bit with a sucker.

Insert a pick between the back cover and the fuselage, and then slowly slide the pick to release the snaps on the middle frame.
It is worth mentioning that the Xiaomi Mi Max 2’s back cover is very easy to remove. I have never found it so easy to remove a mobile phone’s back cover before.

In the separation of the back cover and the fuselage, it should be noted that the fingerprint module cable on the back cover is still connected to the motherboard.
Disconnect the fingerprint module cable from the motherboard with a crowbar.

We found a chip marked with “5001 8500 1649” on the back of our fingerprint cable, but it’s unclear which manufacturer it came from. If you know, please tell us.

Xiaomi Mi Max 2 uses the classic three-stage fuselage. 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.

Xiaomi Mi Max 2 uses a large piece of metal plate used to fix the connector on 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, the following should be the Snapdragon 625 processor and RAM. As with most midrange machines, the integration is not particularly high, whether it’s the motherboard or the bottom board.

The front camera module is really small; it comes from QTech, and the model is F5E8YAR, but we did not find this product on Q-Tech’s official website.

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

The touch chip is from FocalTech, model FT5446DQS.

Remove all screws securing the loudspeaker and bottom board.

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

The bottom 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 3.85V, 5300mAh Li-ion polymer battery, and the model is BM50. It is manufactured by Sunwoda Electronic.

Summary
Most of the components are modular and can be replaced independently.
The battery can be replaced by pulling out the adhesive tape.
It is very easy to remove the back cover.
The middle frame is made of plastic material.
