Modern flagship smartphones like the Xiaomi Mi 10 are complex engineering designs where every millimeter of interior space is carefully planned. The need to open the device can arise for various reasons, from the banal replacement of a bloated battery to serious repair of the motherboard after moisture hits. Understanding how to properly open the Xiaomi Mi 10 is a critical skill for any enthusiast or craftsman looking to extend the life of the gadget.
However, it is worth noting that the process of dismantling this smartphone is fraught with certain risks: the back panel of the device is glued around the perimeter with a powerful layer of glue, and the internal components are tightly packed and protected by metal screens. Careless movement can lead to damage to the plumes or cracks in the glass, so before starting work, you need to carefully study the algorithm of actions and prepare the appropriate tool.
In this article, we will take a detailed look at all the steps of opening the case, paying special attention to hidden screws and fragile connections. You will learn what tools will be required for safe operation, how to warm up the glue and in what sequence to disconnect the modules.
Tools and workplace preparation required
Before you start disassembling, you need to organize the workspace, the surface should be clean, flat and preferably not conduct static electricity. The ideal solution would be an antistatic mat, but you can also use a regular desk, covered with clean cloth. The absence of dust minimizes the risk of debris falling under the display or into the charging connectors.
To do this successfully, you'll need a specialized toolkit. Using inappropriate items like kitchen knives or thick screwdrivers can cause permanent damage to the case. A quality tool is the key to careful disassembly and the absence of scratches on the smartphone frame.
- 🔧 Dryer or thermal film for softening the adhesive around the perimeter of the body.
- 🛠️ A set of precision screwdrivers (star Torx) T5 and the Phillips cross #00).
- 🎴 Plastic mediators, sucker and thin metal scalpel.
- 🧲 Magnetic mat or organizer for sorting screws of different sizes.
- 🧤 Antistatic gloves and dielectric-coated tweezers.
Special attention should be paid to the source of heating. A normal household hair dryer often does not give enough temperature, so it is better to use a power-adjusted building hair dryer or a special thermal film. OLED-display or cause the battery to bloat, so temperature control is a key safety factor.
☑️ Preparation for the opening of Xiaomi Mi 10
The procedure of heating and removing the back cover
The first step in disassembling modern smartphones is to dismantle the back panel. In the Xiaomi Mi 10 model, it is attached to a two-sided tape, which becomes elastic when heated. Put the smartphone down on a soft cloth or a special mat to avoid scratching the display during operation.
Turn on the dryer and warm up the perimeter of the device evenly. Keep the heat source at a distance of 3-5 cm from the body, constantly moving it so as not to overheat one point. The optimal heating temperature is about 80-90 degrees Celsius. The process takes about 2-3 minutes, after which the glue should soften.
⚠️ Warning: Do not heat up the center of the smartphone, where the main camera and battery are located. Local overheating in this area can damage the camera matrix or, worse, to fire battery components.
After warming up, attach the suction cup to the bottom of the back cover, just above the Mi logo. Pull the suction cup up, creating tension, and in the resulting gap, carefully insert a plastic mediator or a thin blade. Driving the tool along the faces, trying not to immerse it deeper than 3-4 mm, so as not to damage the plumes coming from the side buttons.
💡
If the back cover cracked when removed, do not try to glue it with superglue before installing a new one - it is better to immediately replace the glass with a new one, since microcracks can lead to loss of moisture protection and dust getting inside.
Be careful in the area of the main camera module, where the layer of glue can be thicker, and the structure of the module can be more fragile. If the lid does not lend itself, add a little more heat, but do not use excessive physical force, patience at this stage will save you money to buy new parts.
Dismantling protective screens and disconnecting plumes
After successfully removing the back cover, you will see the smartphone’s internal device, closed with black plastic and metal plates, which act as dust protection and electromagnetic interference shielding. In the Xiaomi Mi 10, they are secured with many screws of different calibers that need to be twisted out.
Use a Torx T5 screwdriver to remove metal plates. The screws can have different lengths, so it's crucial to sort them out as you twist them. If you mess up the screws, you risk damaging the thread in the case or, worse, punching the board with a long screw when you build. Accuracy is crucial here.
When you remove all the shields, you get access to the plume connectors. The first thing you need to do is turn off the battery. Find the battery connector (usually located at the bottom or center of the board) and gently disconnect it with a plastic blade. Only after the device is de-energized can you start turning off the display, cameras and other modules.
| Component | Location. | Type of connector | Features of withdrawal |
|---|---|---|---|
| Battery | Lower part (under the screen) | Wide flat | First turn it off! |
| Display. | Top of the pay | Wide layered | Fragile, requires care. |
| Main camera. | Centre/Upper | Small square. | Often covered by metal |
| Charging charges | Bottom of the hull | Long plume | Goes through the whole body. |
When disconnecting the plumes, use plastic tools. Metal tweezers can damage the contacts or short the residual charge of the capacitors. Some connectors have latching latches that must be bent before pulling the plume. Carefully inspect the connection before exposure.
Why can't you pull the plume itself?
Removal of the battery and work with the glue layer
Replacing the battery in the Xiaomi Mi 10 is one of the most common causes of disassembly. The battery in this model is glued to the frame of the body quite firmly, which is the standard for modern flagships. Simple picking out to dry is almost guaranteed to lead to deformation of the battery, which is strictly forbidden due to the risk of fire.
To safely extract, reheat the battery area through the open back (if the lid is already removed) or through the housing if you are working in the replacement phase. Optimally use special adhesive solvents such as the B-7000 or isopropyl alcohol, injecting them with a thin needle under the edges of the battery.
- 🧪 Apply a little alcohol or solvent around the perimeter of the battery.
- ⏳ Wait. 2-3 minutes for the liquid to penetrate the glue layer.
- 🪡 Carefully tuck the edge of the battery with a plastic shovel.
- 🧵 Use a special exhaust thread or a thin line to "saw" glue.
During the recovery process, monitor the integrity of the battery shell. any puncture or deep scratch on the lithium polymer cell can cause an instant chemical reaction. If you notice that the battery has started to swell or changed shape, immediately stop working and dispose of it in a special container.
⚠️ Note: It is strictly forbidden to use metal tools (knives, scalpels) to tweak the battery.The metal easily penetrates the thin shell of the cell, which leads to short circuit, smoke and possible ignition.
After removing the old battery, clear the seat of the residue of the old glue. The surface should be perfectly smooth and clean before installing the new cell. Use pre-cut strips or double-sided electronics tape to fix the new battery, avoiding the use of liquid "Moment" glue, which can damage components during future disassembly.
💡
Safe battery extraction is possible only with the use of a chemical glue softener and plastic tools; mechanical action without preparation is dangerous.
Removal of the display module and brackets
If your goal is to replace a broken screen, the process gets complicated. In the Xiaomi Mi 10, the display is glued to the frame, not just inserted into it. This means that replacing the glass or matrix often requires repainting the entire module or using a separator to separate the glass and matrix, which is a task for a professional service center.
However, if you just need to remove the module to access the underlying components or to replace the body, proceed carefully. After turning off all the plumes and twisting the screws around the perimeter (which may have been hidden under decorative stickers or frames), the module can be gently lifted.
Use a suction cup and a mediator to separate the display from the frame. Movements should be smooth, without jerking. Inside, thin plumes of buttons or sensors can pass, which can be easily broken with a sloppy jerk. Visual control of all connections is mandatory at every millimeter of screen lift.
And you can see the dynamic speaker and proximity sensor brackets, which are often attached to the display module or the top of the frame, and when you take off the screen, make sure that these little pieces don't hang on the plumes or fall inside the case, where they're going to be hard to find.
Assembly of the device and verification of functionality
The Xiaomi Mi 10 is assembled in reverse order, but with a number of important nuances. Before the final fixation of the back cover, you need to conduct an initial health check. Connect the display plume and battery, then try to turn on the device, which will make sure that all the connectors are inserted to the stop and work correctly.
Check the basic functions: touchscreen response, camera, microphone, speaker and vibrator. Make sure the proximity and light sensor is functioning correctly. If you find a malfunction, disassemble the device again and double-check the connections without relying on "maybe."
For final assembly, apply a new layer of glue to the body frame. Use a special electronics glue (such as the B-7000) with a thin, uniform stripe. Avoid getting glue inside the case, on the camera or into the connectors. Press the back cover and lock the device with rubber harnesses or load for 1-2 hours before drying out completely.
The final step is to install the screws. Twisting them evenly, without undue effort, so as not to break the thread in the plastic bushings. Pay special attention to the screws around the camera module - they must be twisted tightly, but without fanaticism, so as not to damage the lenses.
