Modern smartphones are becoming more and more difficult to maintain, and the Xiaomi Redmi Note 10 is no exception.The device body is made of a combination of glass and plastic, which requires the wizard to be more accurate and use a specialized tool.Incorrect disassembly can lead to damage to the plumes or cracks on the back cover, so it is important to follow the algorithm of actions clearly.
The main difficulty when working with the Redmi Note 10 is the absence of screws holding the back panel, and the presence of a powerful adhesive layer around the perimeter. AMOLED-This is why temperature is a critical parameter that must be monitored throughout the entire dismantling process.
Before you start a physical intervention, you need to prepare the workplace and make sure that you have all the tools you need. The absence of even one element, such as a suction cup or a thin mediator, can significantly complicate the task and increase the risk of accidental damage. In this article, we will take a detailed look at each stage of disassembly so that you can safely replace the battery, display module or other internal components.
Tools and workplace preparation
A good disassembly of a smartphone is impossible without a properly selected set of tools. To work with the Xiaomi Redmi Note 10, you will need not only a standard cross screwdriver, but also specific devices for working with adhesive joints. Ignoring this stage often leads to the fact that the master spends more time finding the right item than repairing it.
It is important to ensure good lighting of the work area, as many plumes and connectors are miniaturized and can be damaged by careless handling. Using an antistatic mat will help protect electronics from static discharge, which is harmful to chips. It is also recommended to use a magnetic card to sort screws, since the device uses fasteners of different lengths.
For successful removal, you will need the following tools:
- 🔥 A hair dryer or thermophen to soften glue
- 🔧 Set of screwdrivers (cross-haired) P2, Pentalobe)
- 🎴 Plastic mediators and sucker
- 🧲 Magnetic mat or organizer for screws
- 🧴 Isopropyl alcohol or glue removal liquid
⚠️ Note: Using a metal blade instead of a plastic mediator to open the case can cause battery puncture and fire.
In addition to physical tools, be sure to program the device. Before starting any dismantling work, you need to make a full backup of data, as the repair process may require turning off the battery, which sometimes leads to a reset or loss of data if the memory plume is accidentally damaged.
Primary actions and extraction SIM-tray
The first step in the process of disassembling the Xiaomi Redmi Note 10 is to completely turn off the device. This is a critical security point, since working with the phone on can cause a short circuit on the board when the plumes are disconnected. After turning off, check that the notification indicators are turned off and the device does not respond to button presses.
The next step is to remove the tray for SIM-This is done with a special paper clip that comes with the kit, or a thin tip, and the tray is on the bottom end of the case, and it needs to be pulled strictly perpendicularly so as not to damage the tray's inner frame or the reader's contacts.
After removing the tray, carefully examine the hole: there should be no dust or pile inside, which could get deeper into the case during further disassembly. Some craftsmen recommend taped the tray hole with a piece of paint tape during work to prevent small debris from entering the motherboard.
💡
Before inserting a paper clip into the tray hole, make sure you hold the phone face up so as not to scratch the back cover with the tool.
Now that the tray is removed, you can move to heating the case. Warm the perimeter of the back cover evenly with a hairdryer, paying special attention to the corners and edges. Don't keep the hairdryer at one point for too long to avoid local overheating of the glass.
Removing the back cover and accessing internals
The process of separating the back cover from the frame of the body is one of the most delicate steps. After warming up for 2-3 minutes, you need to carefully insert a thin mediator or scalpel blade into the junction between the glass and the frame. The movements should be sliding, without sharp jerks, so as not to break the glass.
Move the tool around the perimeter, gradually cutting through the adhesive layer. It's important to feel resistance: if the tool is tight, then the glue in this place is not yet warmed up, and additional heating is required. The back cover of the Redmi Note 10 has a complex adhesive geometry, so do not try to remove it immediately after cutting through one edge.
When the perimeter is complete, you can use the suction cup to finalize the lid, pull the suction cup up while holding the body with your second hand, and if the lid doesn't lend itself, don't use force -- you'd better add a little more heat.
For clarity, consider the main components that become available after removing the lid:
- 🔋 Battery with connection plume
- 📱 Lower motherboard with connectors
- 🔊 Dynamics and vibrator
- 🔌 Display plumes and buttons
⚠️ Attention: Under the back cover is a fingerprint scanner plume (in some versions) or antenna contacts.
After removing the lid, it is recommended to immediately clean the inner surface of the frame of the residues of old glue, this will ensure reliable fixation of the new lid or high-quality sealing during reassembly.
Dismantling the protective panel and disconnecting the plumes
When you take the back cover off, you'll see a black plastic panel that covers the main components, and it's mounted on a lot of screws of different sizes, so it's important to keep the order of how you twist them and remember the location, and the screws can vary not only in length, but also in diameter of the thread.
Use a magnetic-tipped screwdriver to extract the fastener, but be careful: the magnet can damage sensitive elements if you bring it too close to the camera or speaker. After twisting all the screws, the panel is removed with a light motion, opening access to the battery compartment and connectors.
The first thing you do is turn off the battery plume, and this is done by bending the plastic connector upwards with a plastic blade or nail, and only after the battery is turned off can the plumes of the display, touchscreen and other modules be safely disconnected.
The main stages of work with plumes:
- Disconnect the battery connector
- Remove the metal protective plate over the display connectors
- Disconnect the main display plume
- Disconnect the touchscreen plume (if it is separate)
☑️ Check before disconnecting the plumes
When disconnecting the plumes, never pull the wires themselves or the flexible part, the impact should be solely on the rigid plastic connector. A sudden movement can lead to the breakage of current tracks, the restoration of which requires a microscope and a soldering station.
Replacement of the battery and work with the glue layer
In the Xiaomi Redmi Note 10, the battery takes up a significant portion of the internal volume and is attached to double-sided tape. The adhesive clutch is very strong, and trying to just pull the battery out can cause it to deform or damage. It is strictly forbidden to heat the battery directly because of the risk of ignition.
To safely extract, the method of "strings" or special hoods with suction cups is used, the thread (for example, a dental floss or a line) is wound at the end of the battery and cuts through the adhesive layer with sawing movements, the movements must be smooth, without jerks, so as not to damage the soft body of the battery.
If you plan to install a new battery, be sure to clear the seat from the old glue to a state of perfect smoothness. Any irregularities can cause the new battery to fit loosely, which can cause it to bloat during operation.

What to do if the battery is swelling?
After installing the new battery and connecting the plume, do not rush to close the case. Turn on the device and check whether charging is underway and whether the battery is detected in the system, this will avoid re-disassembly in the event of a new component failure.
Assembly of the device and verification of functionality
The Xiaomi Redmi Note 10 is assembled in reverse disassembly, but there are some nuances associated with applying a new adhesive. For reliable sealing, it is recommended to use a special adhesive B-7000 or ready-made adhesive frames that provide factory moisture protection (although complete water resistance after opening is not guaranteed).
Apply a thin layer of glue to the frame of the body, avoiding getting on the camera and speaker. Let the glue dry a little (about 1-2 minutes) before installing the back cover, so that it does not squeeze out when pressed. After installing the cover, fix it with rubber bands or a load for 15-20 minutes until full grasp.
The final step is to make sure that all the functions of the device are fully functional, make sure that all the communication modules, cameras, sound and vibration are working, and pay special attention to the touchscreen, swipe your finger around the edges of the screen to make sure that there are no dead zones that may have arisen due to improper installation of the plume.
⚠️ Warning: If the phone doesn't turn on after assembly, don't panic. Check to see if the battery plume is fully inserted and if it's latched correctly. Sometimes the connector requires a stronger but more gently pressed press. Successful assembly and launch of the device is an indicator of your professionalism and attention to detail. Compliance with all stages of the instructions allows you to extend the life of the gadget and save significant money on the services of the service center. 💡Cleaning old glue and installing a new sealant correctly ensures that the smartphone will last a long time and will not fall apart in a month. Can you disassemble the Redmi Note 10 without a hairdryer? Theoretically, you can use special adhesive solvents, but it is extremely risky. The liquid can leak into the case and damage the electronics. Heating remains the safest and most effective way to soften the glue. Yes, opening the case and damage to warranty stickers (if any) automatically voids the manufacturer's official warranty. Self-repair is recommended only on devices with an expired warranty. Which glue is best used for the back cover? The best choice is the glue. B-7000 or T-7000. They have good elasticity after drying, which is important for devices that are subject to vibrations, and allow you to reopen the case if necessary without destroying the components. What if only glass broke, and the image is? In Redmi Note 10, you use the same device. AMOLED-It's a screen where the touchscreen and the matrix are soldered into a single module, and it's impossible to replace the glass at home, and it requires expensive separation equipment, and it's easier and more reliable to replace the entire module.
