How to disassemble Xiaomi Mi Play: detailed instructions with photos and nuances

Xiaomi Mi Play is a budget smartphone with good specs, but like any technology, it can require repairs, from replacing the battery to cleaning the connectors. Disassembly of this device has its own peculiarities due to the adhesive mounting of the rear cover and fragile plumes. In this article, you will find a step-by-step instruction with photos, a list of necessary tools, as well as critical points that will help to avoid damage.

It's important to understand that the disassembly of the Xiaomi Mi Play (M1901F7T) is different from other Mi or Redmi devices, there's no removable battery, and the body is glued around the perimeter, which requires care. If you've never disassembled your phones, practice on an unnecessary device or go to a service center. But if you decide to act on your own, follow our recommendations.

Preparation for disassembly: tools and security measures

Before you start, make sure you have everything you need, and the lack of the right tools is the main cause of damage to the body or internal components.

• 🔧 Plastic mediators (2-3 (a) - for separation of the back cover without scratches.
• 🔨 Screwdriver cross (PH00 or PH0) — Xiaomi Mi Play screws.
• 🧲 Magnetic mat or container – to avoid losing small details.
• 🔥 Building hair dryer (or hair dryer with hot air mode) - to soften the glue.
• 📸 Smartphone for photography - fix the location of plumes and screws.

Also, prepare your workspace: a clean desk with good lighting, no crumbs or dust, using metal tools (knives, screwdrivers) to slap the lid can damage antenna lines or displays, and if you don't have plastic mediators, order them in advance (costs a penny).

⚠️ Note: Do not disassemble the Xiaomi Mi Play in humidity above 60% or in a dusty room. getting moisture on the board or dust under the screen can cause corrosion or sensor problems.

Before disassembling completely turn off the phone and remove SIM-If the battery is swelling, don't try to disassemble the device yourself: contact the service.

Step 1: Removing the back cover – how not to damage the antenna lines

The back cover of the Xiaomi Mi Play is glued around the perimeter, and underneath it are antenna contacts that are easily damaged. Heat is the key to successful separation.

1. Heat the back cover around the edges (at ~60°C) with a hair dryer for 2-3 minutes. Keep the hair dryer 10-15 cm away so as not to melt the plastic.
2. Insert a plastic mediator into the gap between the lid and the case (start with the lower left corner where the connectors are located).
3. Carefully drive the mediator along the edge, gradually detaching the lid, and if you feel resistance, heat the area again.

Don't try to rip the lid off suddenly, because there are flexible plumes underneath it (like a fingerprint scanner plume). If the lid doesn't work, check if there are undetached areas on the sides. Often the problem lies in the volume button area.

⚠️ Warning: If you see that the fingerprint scanner plume is severed after the cover has been removed, do not try to stick it yourself.

Step 2: Shutting down the battery – why it’s critical

When you take the lid off, the first thing you need to do is turn off the battery, and the Xiaomi Mi Play board has a black-insulated connector, which is the battery connector, and you need to gently tuck it in with a plastic blade and disconnect it.

A connected battery can short circuit when you accidentally touch the board with a screwdriver or tweezers. Even if the phone is turned off, there's still residual voltage on the board, and turning off the battery will protect both the device and you.

• 🔋 The battery connector is usually located at the bottom of the board (closer to the charging connector).
• 🛠️ Use a plastic spatula, not a metal screwdriver.
• 📷 Take a picture of the location of the connector before turning off – then it will be easier to connect back.

If the connector is stuck and doesn't move, don't pull it. Keep your shoulder blade moving right and left until it weakens. If you damage the connector, you'll have to change it completely.

💡

If you plan to work with the board for a long time (for example, soldering a microphone), seal the battery connector with tape so that you do not accidentally connect the power.

Step 3: Removing the motherboard - the order of spinning screws

The Xiaomi Mi Play board is mounted on 10-12 screws of different lengths, and you can't confuse them in places, because it can damage the body or short circuit.

1. Take a picture of all the screws. The Mi Play uses three types of screws: Short (fix the board to the middle frame); Long (fix the board and the screen module); and rubber pad screws (vibration protection).

Start spinning off the corner screws, then move to the central.

Place the screws on the magnetic mat in order of extraction (or sign a piece of paper).

After unscrewing the screws, the board is still held on several plumes:

• The display plume (the widest, at the top).
• Sensor plume (thin, next to the display).
• The tail of the rear camera (in the upper left corner).

Then, take them out of the way, and then you will be able to pull them out of the way.

Step 4: Screen removal – when it’s necessary and how to avoid damage

Replacing the screen with Xiaomi Mi Play requires cracks, a broken sensor or broken pixels, but the display module is glued to the frame, and replacing it is one of the most difficult operations.

• 🔥 Heat the screen with a hair dryer (temperature) 70-80°C) during 5 minutes to soften the glue.
• 📱 Use screen-separating suction cups (you can buy them in your phone repair kit).
• 🛑 Do not blow the screen with a knife - under it pass the plumes of the sensor and display.

If the screen cracks, put tape on it before heating so that the fragments do not fly apart. When you separate the module, act smoothly: the glue can be very sticky. If the screen does not move away, heat it again.

⚠️ Note: In Xiaomi Mi Play, the sensor plume and display are combined into one module. If you damage it when you separate, you will have to change the entire screen unit, not just the glass.

After the screen is separated, check the integrity of the plumes. If they have tears or scuffs, the module must be replaced. Also, check the metal frame: often when falling, it deforms, and the new screen may not become flat.

💡

Replacing the glass separately from the display module with the Xiaomi Mi Play is almost impossible without specialized equipment, 90% of the time requires replacing the entire module.

Step 5: Replacing the battery – the nuances and choice of a new battery

Battery Xiaomi Mi Play (capacity) 3000 MACh, model BM47) It loses capacity over time, especially when it's used heavily. 2-3 hourly or off 30% It's time to change the battery. Here's how to do it right:

1. Disconnect the old battery with a plastic spatula, and be careful: Lithium batteries cannot be pierced!
2. Remove the residues of the glue from the body (you can use isopropyl alcohol).
3. Apply a new double-sided tape to the battery (comes complete with most replacements).
4. Connect the new battery to the connector and press gently.

When choosing a new battery, pay attention to:

• 🔋 Capacity - must match the original (3000 mAh).
• 🏭 Manufacturer – better to take batteries from Xiaomi or proven brands (Patona, Baseus).
• 📅 Release Date – Do not take batteries older than 6 months (they lose capacity in stock).

After you change the battery, calibrate it: fully charge the phone, then discharge it before turning off and recharge it to 100%. Repeat the procedure 2-3 times.

Common Mistakes in Disassembly and How to Avoid Them

Even experienced craftsmen sometimes make mistakes when disassembling Xiaomi Mi Play, and here are the most common ones and ways to prevent them:

Another common problem is damage to the waterproofing pads. In the Xiaomi Mi Play, they are located around the volume and power buttons. If the gasket is torn, the phone will lose its moisture protection. When assembled, check their integrity and replace them if necessary.

If the phone does not turn on after disassembly, check:

• Is the battery on?
• Are the display and board plumes damaged?
• Whether all screws are twisted (unpatched screws can cause a circuit).
