Xiaomi Mi 5 Disassembly: A Complete Guide with Photos and Warnings

Xiaomi Mi 5 is the iconic smartphone of 2016, which is still used by many users due to its reliability and performance. However, over time, even the best technology requires repairs, whether it is replacing the charging connector, battery or display module. If you decide to disassemble the device yourself, this article will help you to do it correctly, avoiding the typical mistakes.

The Xiaomi Mi 5 has its own nuances: a fragile glass case, adhesive display and a compact layout of internal components. Without preparation, you can damage the plumes, tear contacts or even disable the motherboard. We will analyze each step in detail, from the necessary tools to build back, and also point out critical moments that the manufacturer does not advertise (for example, hidden latches under the battery).

Important: If you've never taken a smartphone apart before, make a sober assessment of your strength. Some operations (such as disconnecting the touchscreen plume) require jewelry accuracy.

Preparation for disassembly: tools and security measures

Before you start, you can assemble everything you need, and if you don't have even one tool, you can damage the body or the internal components, and here's the minimum set.

• 🔧 Plastic mediators (2-3 pc.) - for careful smearing of the body and disconnection of adhesive joints.
• 🔨 The screwdriver. PH00 — medium-board.
• 🔥 Dryer or thermo-air station - for softening the glue under the display (temperature 60-80)°C).
• 🧲 Magnetic mat or organizer – so as not to lose small screws and details.
• 📱 Suction cups (2 pcs) - for removing the display module.
• 🛠️ Tweezers – for working with plumes and small connectors.

Also, prepare the workplace: it should be well lit, draft-free (so as not to blow away small details) and with an antistatic coating (such as a rubber mat). SIM-Memory card – this will save data from accidental damage.

⚠️ Warning: Do not use metal tools to tweak the body! Even a small scratch on an aluminum frame can become a hotbed of corrosion in the future.

If you’re planning a battery replacement, pre-purchase the original battery for the Xiaomi Mi 5 (3,000mAh, BM43 model). Cheap counterparts often have less real capacity and can swell over time.

Removal of the back cover and battery

The first step is to remove the back panel. In the Mi 5, it's mounted on latches and double-sided tape, so you need to be careful. Start by warming up the edge of the body with a hairdryer (don't direct hot air to the display!). The temperature should be comfortable for the hand - about 60°C.

Next:

1. Place the suction cups on the bottom of the smartphone (near the USB-Type C connector).
2. Pull up carefully, creating a small gap.
3. Insert a plastic mediator into the slot and slowly lead them along the edge, disconnecting the latches.
4. After you pass the perimeter, remove the lid, and if it doesn't respond, warm up the problem areas again.

And under the lid, you'll see a battery that's covered in black film, and it's glued to the body, so you can't pull the plume right away, you can tear the contacts off.

• 🔋 Unplug the protective film (it can be glued to the battery or body).
• 🔧 Turn away two screws mounting a metal plate over the battery.
• 🧲 Put a plastic blade on the battery starting at the top edge, and if it doesn't lend itself, warm it up with a hair dryer (not above 70).°C!).

⚠️ Warning: Do not use sharp objects to retrieve the battery! puncture or severe deformation can cause the lithium polymer battery to ignite.

After removing the battery, disconnect its plume from the motherboard. To do this, carefully tweez the black connector with tweezers (don't pull the wires!).

Dismantling of the display module

The Xiaomi Mi 5 display is one of the most vulnerable parts when disassembled, and it's connected to the motherboard with two plumes: the display and the touchscreen, and damage to any of them will lead to a broken screen or sensor.

Procedure:

1. Warm up the display around the perimeter with a hair dryer (temperature 70-80 ° C) for 2-3 minutes. This will soften the glue.
2. Place the suction cups on the bottom of the screen (without overlapping the proximity sensor!).
3. Pull it up carefully, creating a gap. Put a plastic pickup in it.
4. Take a mediator and walk around the perimeter, separating the display from the housing, and be careful about the Home button, where the plumes pass.

After the display is separated, don't lift it up sharply! First, you need to disconnect the plumes:

• 🔌 Turn the screws of the metal plate covering the connectors of the plumes.
• 🧲 Tweezers carefully tuck the black latches of the connectors (they open upwards!).
• ⚠️ Don't pull the plumes, they're fragile, you'd better put a plastic blade on the side.

Now you can take the display module completely off, and you can put it on a soft surface (like a napkin) with the screen down so you don't scratch it.

Extraction of the motherboard and additional components

Once the display and battery are removed, the motherboard is available, and it is attached to the middle frame with several screws and connected to the other components with plumes, and the key here is not to confuse the screws when they are reassembled, as they can vary in length!

Deconstruction procedure:

1. Turn all the screws around the board perimeter (about 10-12 of them), fold them into the organizer in groups.
2. Disconnect the plumes: 📷 Main and front camera modules. 🔊 Dynamician and microphone. 📶 Antenna contacts (they are glued to the board, be careful!).

Carefully tuck the board with a plastic blade on the side and lift it. Don't use force -- if something gets in the way, check if all the plumes are disconnected.

Under the motherboard are located:

• 🎤 Microphone – attached to bilateral scotch.
• 📡 Antenna modules – glued to the frame, do not try to tear them off without the need.
• 🔋 Vibromotor - screw-mounted.

⚠️ Note: When removing the fee, do not touch the contacts with your hands. EMMC (memory CPU (Static electricity can damage them without the ability to repair them.

If you need to replace the USB-Type C connector, it's on a separate childboard, and you need a soldering station to dismantle it, which is almost impossible to do manually.

💡

Before disconnecting the plumes, take a picture of their location on the board, which will help not confuse them when you reassemble them, especially if you are disassembling a smartphone for the first time.

Replacement of the battery: nuances and errors

The battery is the most worn component in Xiaomi Mi 5. After 3-4 years of operation, its capacity drops by 30-50%, and battery life is reduced by 2-3 times. Replacing the battery is one of the most common reasons for disassembling this smartphone.

Here's what you need to know:

• 🔋 The original battery has a label. BM43 and capacity of 3000 mAh Analogues (for example, from Zoppini or Camelion) may have a lower real capacity.
• 🔧 Glue: The new battery must come with double-sided tape. If it's not, use glue. B-7000 (thin-layer!).
• ⚡ First on: after replacing the battery, charge the smartphone to 100% and perform 2-3 cycles of full discharge / charging to calibrate the controller.

Common mistakes in replacement:

Once you have installed the new battery, check it to full assembly: plug the plume into the board and turn on the smartphone (without the display). If it loads and shows the correct charge level, it's okay.

💡

Never use a battery that is swollen or has visible damage! even if the smartphone turns on, the risk of fire remains high.

Xiaomi Mi 5: reverse order and verification

The assembly of the device should take place in reverse order, but taking into account several key points:

1. Before installing the display, clean the frame of the residues of old glue with isopropyl alcohol. New glue (or bilateral tape) apply a thin layer.
2. When connecting the plumes, make sure that the connector latches are completely closed. An insufficiently dense connection can lead to artifacts on the screen or a broken touchscreen.
3. Screw the screws cross-twisted to avoid skewed boards. Don't put too much effort - the thread in the aluminum frame easily breaks.
4. After assembly, check all functions: 📱 Touch screen (responsiveness, multi-touch). 🔋 Charging (connect the cable and make sure the current is going). 📷 Cameras (front and main). 🎤 Microphone and speakers (record voice note).

If after assembly the smartphone does not turn on:

• Check if the battery plume is connected.
• Make sure the power button is not recessed (sometimes the case fixes it).
• Connect to charging for 10-15 minutes – the battery may be discharged.

⚠️ Warning: If the screen flickers after assembly or colored stripes appear, the display plume is likely damaged.

If everything works correctly, seal the screws on the back cover with a sealant (for example, Loctite 401) to protect them from corrosion, and it is also recommended to paste a new protective film on the screen.

Frequent problems after disassembly and their solution

Even with careful disassembly, there can be problems, and here are the most common ones and how to fix them:

If the problem is not solved on your own, contact the service. For example, damage to the motherboard (especially PMIC or CPU chips) requires professional repair using a soldering station and a microscope.

Also, after disassembly, the calibration of the accelerometer or gyroscope can be lost, in which case resetting to the factory settings will help (Settings → Additional → Recovery and Reset).
