The Xiaomi Mi 5, released in 2016, is still in the line for many users due to its compact body and quality characteristics. However, time takes its toll: the display breaks, the battery wears off or the charging plume departs. In such situations, there is an urgent need to disassemble the device on its own to replace the failed component without going to the service center.
The opening process of this flagship has its own characteristics, which distinguish it from more modern models with plastic bezel. It uses a glass back panel, which requires increased accuracy and the correct temperature. Before starting work, it is important to understand that disassembling the Xiaomi Mi 5 is a risky procedure that requires the appropriate tool and patience.
In this article, we will take a detailed look at each stage of dismantling, from heating the case to turning off the plumes. You will learn which screws to unscrew first and how to safely separate the display module. Compliance with the technology will allow you to maintain the tightness (as much as possible after opening) and functionality of the gadget.
Tools and workplace preparation required
A high-quality disassembly is impossible without a specialized tool. Using knives or screwdrivers of the wrong size can damage the internal plumes or chips on the glass. You will need a set of precision screwdrivers, including a Phillips #00 cross and possibly a Torx star, although the Mi 5 mostly uses standard screws.
You need heat to separate the back cover. You can use a professional separator, but you can use a regular hair dryer or a heating plate at home, you also need suction cups to lift the glass, plastic mediators (scapula) and tweezers. Don't forget about isopropyl alcohol to dissolve the glue.
- 🔧 Set of screwdrivers (cross, flat, flat)
- 🔥 Dryer or heating panel
- 🏺 Suction and mediators
- 🧪 Isopropyl alcohol or special solvent of glue
⚠️ Warning: The workplace must be well lit and free of metal objects that may accidentally close the board contacts.Cover the table with an antistatic mat or clean cloth.
Space organization is key to success. All screws should be folded into a magnetic mat or signature cells, because they can vary in length. A lost screw or a confused length can damage the motherboard when assembled.
Removal of the rear glass panel
The first step is always the extraction. SIM-This elementary action is often ignored, which causes the tray to break when you try to remove the lid, and then you need to warm up the perimeter of the back cover, and the glue that locks the glass softens at a temperature around the back. 80-90 degrees Celsius.
Warm up the edges of the smartphone evenly for 2-3 minutes, constantly moving the hair dryer so as not to overheat one point. After heating, attach a suction cup to the bottom of the lid and gently pull upwards, creating a gap. Insert a plastic spatula into the resulting gap.
Safety Techniques for Heating
We're going to use the perimeter to keep it from going too deep, so that you don't damage the fingerprint sensor plume at the bottom, and you need to be smooth, heated, and if the lid is tight, add more heat, but don't use force.
⚠️ Warning: The Xiaomi Mi 5 glass back is very fragile. It can crack if you jerk or heat unevenly.Be prepared for the lid to have to be replaced.
Dismantling the protective plate and disconnecting the plumes
When you take the back cover off, you'll see the interior layout, and the centerpiece is a large metal plate covering the battery and the bottom of the motherboard, and it's secured by a lot of screws of different calibers.
Unscrew all the visible screws that hold this plate. Notice the screws in the corners and near the connectors. Some of them may be hidden under stickers or plugs. After unscrewing, carefully remove the metal screen by putting a plastic blade on it.
Now you have to turn off the power, and the first thing you do is you disconnect the battery plume, which is a critical step to keep things safe, and only after you turn off the main plumes of the display and touchscreen, which are at the top of the board.
- 🔋 Disconnect the battery connector
- 📱 Disable the display plume
- 🖐️ Turn off the touchscreen plume
- 🔌 Remove the tail of the lower fee (subpayments)
Use a plastic blade or nail to turn off the plumes. Metal tools are prohibited here, because you can damage the contacts on the connectors. Act confidently, but without undue effort.
Removal of the battery and replacement of elements
In the Mi 5, the battery is glued to the body quite firmly, and it often requires removing the motherboard because it covers part of the battery, but in some cases you can try to tamper with the battery through the bottom end, if the design allows.
If the battery is held on double-sided tape, use plastic cards or special tapes to extract it. Never pierce the battery case or bend it. Damage to the lithium polymer cell can cause fire.
☑️ Pre-assembly check
When installing a new battery, make sure the connector is properly oriented. After connecting the battery, take your time to assemble the phone completely. First, check if the device responds to the power button.
⚠️ Warning: The new battery may have a protective film on the contacts. Be sure to remove it before installing it, otherwise the phone won't turn on.
Scheme of screws and table of components
One of the major challenges in building is the right screws, which are of different lengths and threads, and putting a long screw into a short hole can break through the board tracks or damage the body.
Below is a table of the main components that most often require replacement, and their location in the structure of the smartphone.
| Component | Location. | Firming | Difficulty replacing |
|---|---|---|---|
| Battery | Center, under a metal plate | Glue, plate screws | Medium |
| Display module | Front part | Perimeter glue | Tall. |
| Imprint scanner. | The bottom part, under the button | Plate, glue. | Tall. |
| Charging charges | Bottom of the hull | Screws, plume. | Low. |
Replacing the display in the Xiaomi Mi 5 often requires re-painting the entire module into a frame, since the glass here is integrated with the matrix. When replacing the Home button with a fingerprint scanner, calibration is required, which is only possible using special equipment.
Keep the screws in order. It is recommended to use a magnetic mat with markings or just draw a diagram on a piece of paper, spreading the screws in the appropriate places.
Assembling and checking functionality
The assembly is reversed, and before the final fixation of the back cover, you need to check all the functions: sound, vibration, sensor, cameras and communication modules. SIM-map and make sure the network is caught.
Pay special attention to the plume of the fingerprint scanner. It's very thin and easily torn. When you put it down, make sure it's not clamped or cracked. If the scanner doesn't work after assembly, it's likely that the module itself or its plume is damaged.
💡
Use the B-7000 adhesive to hold the back cover, which is elastic after drying, which will make future openings easier, and holds the glass well.
Apply the new glue to the frame in a thin layer. Let it dry a little (1-2 minutes), then press the back cover. For better fixation, you can use stationery gums, wrapping them around the phone for 15-20 minutes.
⚠️ Warning: Do not turn on the phone immediately after assembly if you have changed the battery. Let the glue grip and check for no short circuits visually.
