Xiaomi Mi 6 is the legendary flagship of 2017, which is still popular due to its powerful hardware and high-quality assembly. However, even such a reliable device requires repair over time, whether it is a battery replacement, dust cleaning or recovery after a fall. Disassembly Mi 6 has its own features – from non-standard attachment of the rear cover to fragile plumes that are easily damaged by careless actions.

In this article, you will find detailed step-by-step instructions with photos of key steps, a list of necessary tools and unique tips to help avoid typical errors. We will learn how to safely remove the rear panel, disconnect the battery, dismantle the motherboard and other components without risking damage to the smartphone, and pay special attention to the hidden “traps” that the Mi 6 design contains, such as the adhesive battery mount or fragile display connector.

If you've never taken a smartphone apart before, don't worry. With the right approach and patience, even a beginner can do the job. The key is to follow the instructions and take your time. And if you're an experienced craftsman, you'll find some useful nuances that are not written in the standard manuals.

Preparation for disassembly: tools and security measures

Before you start disassembling the Xiaomi Mi 6, make sure you have everything you need. Inappropriate tools are one of the main causes of damage to the body or internal components.

• 🔧 Plastic mediators (2-3 - for gently putting the lid on and disconnecting the adhesive joints. Metal tools can leave scratches!
• 🔨 Cross screwdriver PH00 — A typical screwdriver won't work: the screw heads in the Mi 6 are small and easily lickable».
• 🔥 A hair dryer or a thermo-air station to soften the glue under the battery, the temperature should not exceed 80°C, otherwise you risk damaging plastic parts.
• 🧲 Magnetic mat or screw container to keep the small parts intact. The Mi 6 uses 12 screws of varying lengths!
• 📱 Suction cup (optional) - will help remove the screen if the glue is too strong. But don't overdo it: the glass can crack.
• 🔋 Isopropyl alcohol (90%+) — to clean the contacts and remove glue residues, acetone or solvents should not be used!

Also, prepare the workplace: it should be well lit, without drafts (dust can get inside the smartphone) and with enough space for laying out parts. Place a soft substrate on the table (for example, a napkin or foam) so as not to scratch the case.

⚠️ Warning: If your Mi 6 has been in water or has been hit hard, disassembly can be dangerous! corrosion on the board or damaged components can lead to short circuit.

Step 1: Removing the back cover – the main mistakes and secrets

The Xiaomi Mi 6's rear panel is mounted on 12 screws and adhesives around the perimeter, and many newcomers try to smack it with a knife or a metal spatula -- a gross mistake that leads to scratches or cracks, and even if the lid is removed, there will be traces on the body.

The correct algorithm:

1. Turn off your smartphone and remove the tray for SIM-cards (use a paper clip or special key).
2. Unscrew all the screws around the perimeter. In the Mi 6, they're of different lengths -- remember or take a picture of where the screws were! The screws under the camera are shorter than the others.
3. Heat the edges of the cover with a hair dryer (temperature) 60-70°C) during 1-2 It'll soften the glue.
4. Insert a plastic mediator into the gap between the lid and the frame (start at the bottom edge where the connector is) USB-C). Carefully lead the tool around the perimeter, separating the glue.

If the lid doesn't lend itself, don't force it! You better warm up the problem area again. In Mi 6, there's an antenna cable under the back, which is easy to break if you sloppyly remove the lid. If you hear a crack, stop immediately and check if the cable is damaged.

After removing the cover, you will see:

• 🔋 Battery (stick to the body).
• 📟 Motherboard with protective screen.
• 📶 Antenna modules and cables.
• 🔊 Dynamics and vibrator.

⚠️ Attention: Don't touch the motherboard with your bare hands! Static electricity can damage the chips. Use an antistatic bracelet or at least touch a grounded metal object before work.

Step 2: Battery shutdown – Why do it first

Before any manipulation with the insides of the smartphone, be sure to disconnect the battery. Even if the device is turned off, there is a residual voltage on the board, which can cause a short circuit when accidentally touching the contacts.

In Mi 6, the battery connector is placed under a protective black film to reach it.

1. Remove the black protective film from the motherboard (it is attached to Velcro).
2. Unscrew two screws that fix the metal plate over the battery connector.
3. Carefully put the connector on the plastic mediator and unplug the plume.

If the battery is swelling, don't try to remove it yourself, because the risk of fire is too high, in such cases, it's better to go to the service center. The normal battery should be flat, without deformation.

Once the battery is turned off, you can start dismantling other components, but remember, every connector and plume in the Mi 6 is fragile, for example, the display plume consists of several thin wires that are easy to break.

Step 3: Dismantling the motherboard – complexity and life hacks

The Xiaomi Mi 6 motherboard is mounted on 8 screws and several adhesive points, and it is also connected to:

• 📞 Display plume.
• 🔊 Dynamic plume.
• 📶 Antenna cables.
• 🔋 Charging connector (USB-C).
• 🎚️ The loop of the switch on and volume control.

Procedure:

1. Unscrew all the screws that lock the board. Notice that the two screws under the camera are shorter than the others.
2. Disconnect all the plumes and connectors. Start with the antenna cables, they're the most fragile.
3. Carefully tuck the board with a plastic mediator, and it can stick to the heat sink.

In the Mi 6, a second microphone (for noise reduction) is hidden under the motherboard, which is easy to miss and damage if the board is not carefully removed, and be careful with the flexible plume of the power button, which often breaks off when sudden movements.

⚠️ Warning: If you're disassembling the Mi 6 to replace the display, don't rush to take off the old screen! First check if the new module is working. There are times when, after assembly, it turns out that the display is defective and the old one is already damaged.

💡

Before removing the motherboard, take a picture of all the plumes and connectors, which will make it much easier to reverse assemble, especially if you are a beginner.

Step 4: Replacing the battery – how not to damage the smartphone

The battery in the Xiaomi Mi 6 is one of the most vulnerable parts, and over time it loses capacity, swells up or refuses to hold a charge, and replacing the battery is the most common reason for disassembling this smartphone, but improper extraction can lead to:

• 🔥 Fire (if the battery is damaged).
• 💥 Body rupture (bloated battery presses on screen).
• 🔌 Damage to the charging connector (if you pull the battery with force).

Instructions for replacement:

1. Disconnect the battery from the motherboard (as described in Step 2).
2. Heat the back of the battery with a hairdryer (70-80°C) during 3-5 The glue under the battery is very strong!
3. Put a plastic blade in a place where there are no components (for example, near the connector). USB-C).
4. Carefully pull on a special black tape (pull-tab), if you have one. If there is no tape, use a plastic mediator to slowly separate the battery.
5. Remove the remains of the glue from the body with isopropyl alcohol.
6. Install a new battery by pre-removing the protective film from the adhesive layer.

When you install a new battery, make sure it's original or certified. Cheap ones can not only fail quickly, but also damage the power controller on the board.

• 🔋 Original Xiaomi battery (article) MBJ407450).
• 🔋 Battery from proven brands: ZMI, Baseus, Remax (marked for Mi 6).

💡

Never use metal tools to retrieve the battery! even a slight damage to the battery shell can cause a fire.

Step 5: Disassemble the display module – when necessary

The display Xiaomi Mi 6 consists of several layers: glass, touch module, OLED-It's usually taken apart to replace broken glass or a faulty touchscreen, but it's a professional challenge to disassemble the display completely, because it requires a lot of work:

• 🔥 Heating to 90-100°C for separation of the adhesive layer.
• 🧲 Use of a powerful vacuum pump.
• 🛠️ Accurate calibration of the new sensor (otherwise, the dead zones will be the new sensor»).

If you only need to replace the glass, you should give the smartphone to the service.

• 🖥️ The appearance of a “spider web” on the screen (due to incorrect pressure when gluing).
• 👆 A broken touchscreen (if the plume is damaged).
• 💡 Uneven illumination (if leakproofness is broken) OLED-panel).

If you still decide to disassemble the display yourself, follow these tips:

1. Heat the screen with a hairdryer around the perimeter, starting at the corners.
2. Use a suction cup to separate the glass from the frame. Don't pull too hard, you can tear the plume!
3. After separation of glass, clean the frame from glue residues with alcohol.
4. When installing a new glass, use it UV-glue and ultraviolet lamp for polymerization.

⚠️ Attention: In the Mi 6, the display plume runs under a metal frame. If you push too hard on the screen when disassembling, the plume can rub against the sharp edges of the frame!

Step 6: Building a Smartphone – How to Avoid Mistakes

Building the Xiaomi Mi 6 after disassembly is as important as dismantling. Many problems (a broken display, no network, fast battery drain) arise precisely from improper assembly.

• 🔧 Screws: Make sure all 12 screws of the back cover are in their places. screws of different lengths - if confused, you can damage the board!
• 📶 Antenna cables: They should lie flat, without inflections. If the cable is twisted, it will not catch the network well.
• 🔋 Battery: Check that the connector is firmly seated in the socket. If the contact is weak, the phone will not charge.
• 📟 Display plume: It should be fixed by a latch. If the plume dangles, the screen will flicker or not work at all.

After assembly:

1. Connect the charger and check if charging is underway.
2. Turn on your smartphone and test all the features: sensor, cameras, speaker, microphone, network.
3. If something does not work, disassemble the phone again and check the connection of the corresponding plume.
