How to disassemble Xiaomi Mi Max: detailed instructions with photos and tips

Why to Disassemble Xiaomi Mi Max and What You Need to Know Before You Start

Disassembling the Xiaomi Mi Max is a challenge that owners face when replacing a battery, repairing a screen or diagnosing malfunctions. This model, released in 2016, is still popular thanks to its large display and reliable “stuffing.” But its design has features: for example, the back cover is glued to the body, and the plumes of the display and battery are fragile.

Before you start, consider that self-disassembly is warranty-free (if it is still valid) and requires care. Mistakes when removing the lid or turning off the plumes can cause flexible cables to be damaged or touchscreen to detach. This article features a step-by-step photo algorithm, a list of tools, and tips on how to avoid typical problems.

If you're not sure about your skills, you'd better go to a service center, but if you're going to do it yourself, follow the instructions and don't miss the training steps.

Training: tools and materials

To disassemble the Xiaomi Mi Max, you need a specialized set of tools, without which you can damage the body or internal components.

• 🔧 Plastic blades (2-3 The metal mediators won't work because they'll scratch the plastic.
• 🔨 Cross screwdriver (PH00 or PH0) — Size matters: too much screwdriver will rip the slats off.
• 🔥 A hair dryer or a thermo-air station to soften the glue under the lid. Optimal temperature is 60-70°C.
• 🧲 Suction cup - will help to lift the cover after heating. Suitable suction cup for glass with a diameter of 3-5 cm.
• 📦 The screw container is to keep the small parts from getting lost.
• 🧴 Isopropyl alcohol (90%+) — acetone or solvent cannot be used to clean glue residues!

Also prepare the workplace: a table with good lighting, an antistatic mat (if any) and a magnifier for inspection of small parts. SIM-Memory card – they can interfere when removing the lid.

Step 1: Removing the back cover

The back of the Mi Max is glued around the perimeter, so it needs to be carefully separated without damaging the plumes.

1. Turn on the dryer at minimum power and evenly warm the edges of the cover for 2-3 minutes. Keep the hair dryer at a distance of 5-7 cm, so as not to overheat the plastic.
2. Place the suction cup closer to the bottom edge (where the charging connector is located) and pull up slightly.If the lid doesn't lend itself, warm up for another 1 minute.
3. Insert a plastic blade into the gap and carefully guide it along the body, separating the glue. Do not use force - the lid should move away with light resistance.

Pay special attention to the area near the volume and power buttons, where the plumes pass. If the lid does not lend itself in some place, do not try to tear it off.

⚠️ Warning: If you see that the plumes of the display or battery have moved away from the connectors after removing the lid, do not try to insert them back immediately.

Step 2: Shutting off the battery

Before any manipulation of the internal components, be sure to turn off the battery. In the Xiaomi Mi Max, it is connected via a connector on the motherboard.

1. Find the orange battery plume (it is located at the top of the board, next to the camera).
2. Carefully slap the connector with a plastic spatula, pulling it up. Don't use metal tools - they can close the contacts.
3. Make sure the connector is completely out of the nest. If it's stuck, sway it slightly left-right.

After turning off the battery, wait 1-2 minutes - this will discharge the residual voltage in the capacitors. Working with the connected battery is dangerous: the risk of short circuit or damage to the board.

Step 3: Removing the motherboard

The Mi Max motherboard is mounted on multiple screws and connected to other components through plumes to remove it:

1. Twisted all the screws around the board (usually 8-10 pieces). Remember the location of each one - they may differ in length!
2. Disconnect the plumes: 📱 Display (white connector at the bottom of the board) 🔊 Speaker and microphone (black connector next to the USB-port) 📷 Camera (small connector in the upper left corner)

Carefully raise the charge for the edges, do not pull the connectors. If it is stuck, check if all screws are twisted.

Once the board is removed, put it on an antistatic surface (like a package of components) and don't charge for metal or conductive materials, which can cause static electricity.

💡

Take a picture of the location of the plumes and screws before disconnecting – this will help to properly assemble the smartphone back.

Step 4: Replace the battery (if required)

The battery in Xiaomi Mi Max is glued to the body with double-sided tape to replace it:

1. Put a plastic blade on the battery from any edge, and if it doesn't lend itself, warm up the body with a hairdryer (not higher than 50°C).
2. Carefully pull on a special black tape (pull-tab), if you have one. If there is no tape, use a shoulder blade, but do not plunge it deep so as not to puncture the battery.
3. After removing the old battery, clean the seat of glue residue with alcohol.Put the new battery on double-sided tape (for example, 3M 9448A).

When installing a new battery, make sure its contacts match the socket on the board. Do not use batteries from other models - even if they look similar, their power controllers may not be compatible.

⚠️ Warning: If the battery is swollen or shows signs of corrosion, do not try to remove it yourself. In this case, it is better to contact the service - the risk of fire or damage to the board is too high.

Step 5: Build a Smartphone

The Xiaomi Mi Max is assembled in reverse order, but with some nuances:

1. Make sure all the plumes are tightly connected - they should snap with a slight click. If the connector is not fixed, check if the contacts are bent.
2. Twisting the screws cross-cross so that the board sits evenly. Don't pull them over, it can damage the thread.
3. Before sticking the back cover, clean the edges and body of the dust and residues of old glue. Use a new double-sided tape or B-7000 glue.
4. After assembly, turn on the smartphone and check the performance: 📞 Calls and microphones 🔋 Charging (check connector and indication) 📸 Camera and flash 🎵 Dynamics and vibration

If something doesn’t work after assembly (for example, the touchscreen doesn’t react or the screen doesn’t turn on), take the smartphone apart again and check:

• All plumes are connected
• Will the cable be clamped somewhere?
• Are there any foreign objects (screws, pieces of scotch) left inside?

💡

The most common build error is a loosely connected display plume, and if the screen doesn't turn on, 90 percent of the time, it's the display plume that's the problem.

Frequent Mistakes and How to Avoid Them

Even experienced craftsmen sometimes make mistakes when disassembling the Xiaomi Mi Max. Here are the most common problems and ways to prevent them:

• 🔧 Teared screws - use a quality screwdriver and do not apply excessive force. If the screw does not go, try to drip a little alcohol on the thread.
• 🔥 Overheating plastic with a hair dryer - keep the hair dryer at a distance and don't direct air flow to one point for longer than 10 seconds.Mi Max plastic can warp at temperatures above 80°C.
• 📱 Touchscreen plume damage -- don't lift the lid too sharply. If the plume does come off, you can solder it in the service, but it's expensive.
• 🔋 Short circuit when you plug in the battery — always turn off the battery before you run the board. If you accidentally close the contacts, check the charge for darkened areas.

If the smartphone doesn't turn on after disassembly, don't panic.

• Not connected battery or power plume
• Damaged motherboard (check for chips or burns)
• The power button's plume has gone.

In most cases, the problem can be diagnosed visually.
