The Xiaomi Mi 6, released in 2017, is still popular with users due to its powerful hardware and robust design, but over time, even such a smartphone may require repairs: a replacement battery, speaker, camera or display module. Disassembly of the Mi 6 has its own features โ there is no removable back cover, and the body is sealed, which complicates the process.
In this article, you'll find step-by-step instructions for disassembling photos, a list of tools you need, and critical warnings to help avoid damage. We'll also tell you which parts most often fail, how to replace them, and what to look for when you build them. If you've never taken a smartphone apart before, don't worry: with the right approach, even a beginner will be able to do the job.
Preparation for disassembly: tools and security measures
Before you start, you can pack everything you need, and without the right tools, you're at risk of damaging plumes, breaking glass, or breaking the mounts, and here's the minimum set you'll need:
- ๐ง Plastic mediators (2-3 (S) for a careful sleeve of the lid.
- ๐จ The screwdriver (PH00 or PH000) โ screw-hole.
- ๐งฒ Magnetic mat or container โ to avoid losing small details.
- ๐ฅ Dryer or thermo-air station - for softening the glue (temperature 60-80)ยฐC).
- ๐ฑ Screen suction cup โ will help separate the display module.
- ๐งด Isopropyl alcohol (90%+) โ glue-cleaner.
If you're planning to replace your battery or plumes, buy original parts in advance. The Mi 6 will be suited to 3,350 mAh batteries labeled MDY09EM (original) or quality analogues from Anker or Baseus. Note: cheap batteries often have understated real capacity and can swell in a few months.
โ ๏ธ Warning: Do not use metal tools (knives, screwdrivers) to lash the lid - this is almost guaranteed to lead to chipping on the aluminum case or damage to the fingerprint plume. Plastic mediators must be thin (0.1-0.2 mm) and flexible.
Before disassembling, turn off the smartphone and remove SIM-If the battery is swelling, don't heat the body with a hairdryer or try to pierce it, and then you should contact a service center, because the risk of fire or damage to internal components is extremely high.
Step 1: Removing the back cover
The back cover of the Xiaomi Mi 6 is glued around the perimeter and is additionally fixed with latches. To remove it, you need to soften the glue and carefully apply the mediator.
- Heat the body with a hairdryer around the perimeter (especially in the area of power buttons and volume) for 2-3 minutes. Keep the hairdryer at a distance of 5-7 cm so as not to overheat the display.
- Apply the suction cup to the bottom of the screen (near the USB-C connector) and pull up slightly. If the lid doesn't lend itself, warm up for another 1 minute.
- Insert a plastic mediator into the gap and carefully guide it along the body, separating the latches. Start at the bottom edge and move counterclockwise.
If the lid doesn't lend itself to some place, don't force it. There's probably some unsoftened glue left. Warm up the problem area again. Typical "complicated" areas in the Mi 6:
- ๐ Around the power and volume buttons (there are additional latches).
- ๐ At the top edge (near the camera) - here passes the antenna plume.
โ ๏ธ Warning: Don't pull the lid too hard, it's connected to the fingerprint scanner plume inside, and if you pull it off, the sensor will stop working, and it'll cost you to replace it. 1/3 smartphone.
When the lid is gone, put it aside carefully, and you'll see the battery, the motherboard, the plumes, and don't touch the contacts with your fingers, because static electricity can damage the chips.

Step 2: Turn off the battery and plumes
Before you continue, be sure to turn off the battery, which will protect the smartphone from short circuit when accidentally touching the board. On the Mi 6 motherboard, the battery connector is located at the bottom (near the USB-C port).
Use a plastic blade or tweezers to gently tuck the connector and disconnect it. Don't pull the wire, you can tear the contacts off. Once the battery is turned off, you can start removing the plumes.
| schleife | Location. | Features of disconnection |
|---|---|---|
| Display module | Top of the board, under a metal screen | Fixed with a latch - put it in a screwdriver. |
| Fingerprint scanner | Under the battery, next to the camera. | Fragile, don't rot or pull the wires. |
| Main camera. | Top left corner of the board | It is a snare, and you must first open it. |
| Charging connector (USB-C) | The bottom edge of the fee | Payed to the fee - do not try to disconnect! |
For convenience, take a picture of the plumes before turning them off, which will help connect them correctly when you build them, and if you replace the display or battery, you can then move on to disassembling them.

If the plume doesn't detach, check if there's a latch that's locked under a black film, tweezers carefully.
Step 3: Dismantling the battery
The battery in Xiaomi Mi 6 is glued to the body with double-sided tape, and to remove it, you need isopropyl alcohol and a plastic spatula.
- Put a few drops of alcohol under the battery (in the gap between it and the body), the alcohol will dissolve the glue, but will not damage the electronics.
- Wait 1-2 minutes, then gently pull the battery off the edge and pull it up. Don't use metal tools!
- If the battery fails, add alcohol and try again. Do not force to avoid damaging the battery (fire risk!).
After dismantling, inspect the battery for swelling or corrosion. If it is deformed, do not try to recharge or reuse it. Dispose of the battery at special reception points.
When installing a new battery, use the original double-sided tape or B-7000 glue. Do not stick the battery "on the eye" - it should fit tightly to the case, but not deform when the lid is closed.

Step 4: Replace the display module
The Mi 6 display is one of the most expensive parts (the original module costs ~5-7 thousand rubles). If the screen crashes or stops responding to touch, it can be replaced by yourself, but the process requires care.
After disabling the display plume (see Step 2), follow the following steps:
- Heat the front of the body with a hair dryer (70-80ยฐC) for 3-5 minutes, which will soften the adhesive that holds the screen.
- Suction the display and gently pull it up, insert the plastic mediators into the gap and separate the screen around the perimeter.
- Disconnect the sensor plume (it is located under metal protection) and remove the display.
When installing a new screen:
- ๐ง Make sure the sleeves are not overwrought.
- ๐ง Apply new glue around the perimeter (for example, LOCA or B-7000).
- ๐ง Press the screen evenly, avoiding bubbles.
โ ๏ธ Warning: If the display fails to turn on after the replacement or artifacts (strips, flickering) appear, check the reliability of the plumes connection. A frequent error is incomplete fitting of contacts due to contamination or bending.
Step 5: Disassembling the motherboard and replacing components
If you need to replace a speaker, a vibrator or a camera, you need to dismantle the motherboard, which is the most difficult step, because the board is mounted with many screws and plumes.
Procedure:
- Unscrew all the screws on the board (about 15 of them, of different lengths!) and fold them in a magnetic container so as not to confuse them.
- Carefully disconnect the remaining plumes (antennas, dynamics, vibromotor).
- Put a plastic blade on the board and pull it out. Don't pull the edges, you can tear the contacts off!
Once you dismantle the board, you'll have access to all the internal components, such as:
- ๐ The speaker is located at the bottom (attached to double-sided scotch).
- ๐ธ The camera is fixed by a screw and a plume.
- ๐ The vibromotor is glued to the body (a hair dryer is needed to replace it).
When you build, look for the heat paste on the processor, and if it's dry, replace it with a new one, like the Arctic MX-4, which will improve heat sink and prevent overheating.

When disassembling the motherboard, be sure to photograph the location of the screws and plumes. One screw screw screw screw that is not screwed correctly can damage the board!
Common Mistakes and How to Avoid Them
Even experienced craftsmen sometimes make mistakes when disassembling the Xiaomi Mi 6. Here are the most common problems and ways to prevent them:
| Mistake. | Effects of consequences | How to avoid |
|---|---|---|
| Use of metal tools | Scratches on the body, damage to plumes | Use only plastic mediators. |
| Hydrogen overheating | Deformation of plastic, detachment of the display | Keep the hair dryer at a distance of 5-7 cm, do not heat for longer than 5 minutes |
| Undisconnected battery when working | Short circuit, board failure | Always turn off the battery first thing. |
| Application of force when removing the lid | Fingerprint plume break | Warm up the glue and use a suction cup. |
Another common problem is improper assembly, when the smartphone does not turn on after repair or not all functions are working.
- ๐ง Check all the cables for reliability of connection.
- ๐ง Make sure the screws are swirled into the correct holes (they are of different lengths!).
- ๐ง Test each feature (camera, speaker, sensor) before final assembly.
If the Mi 6 is not turned on after assembly, check:
- Is the battery on?
- Will the stains be stained (especially the stained).
- Whether all the screws on the board are twisted.
