Xiaomi’s Redmi series is well-deservedly popular for its affordable price and reliability. However, even the most proven devices require maintenance over time, whether it’s battery replacement, dust cleaning or plume repair. Xiaomi’s Redmi 6 is no exception, and many owners face the need to access the gadget’s internal components.
The opening process of this device has its own characteristics, which are important to consider so as not to damage the case or the screen. Unlike modern flagships with glass panels, it uses plastic, which makes the work a little easier, but requires care in handling the latches. If you plan to do the procedure yourself, you will need patience and a minimum set of tools.
In this article, we will take a closer look at each stage of the rear panel dismantling, point out the potential risks and how to avoid common mistakes, and properly prepare the workplace and understand the design of the device is the key to successful repairs without going to the service center.
Tools and workplace preparation
Before you start disassembling any electronic device, you need to have a comfortable and safe space, and the ideal would be a table with good lighting, where you can spread all the tools in the vicinity, and the surface should be clean so that small screws or parts do not get lost in the pile or dust.
To work with the Xiaomi Redmi 6, you will need a specific but common set of tools. Most of them can be found in standard repair kits that are sold in radio markets or online electronics stores. Using inappropriate items such as kitchen knives or thick screwdrivers can lead to scratches on the body or break the thread.
Be sure to prepare the following tools for effective work:
- 🔧 Thin metal blade or mediator for snapping the body.
- 🔩 Phillips sized cross screwdriver #00 or #0 for screw twisting.
- 🌡️ A hair dryer or special heating pad to soften the glue (if any) or simply to gently open.
- 🧲 Magnetic mat or container for folding screws so they do not fly apart.
Static electricity can damage sensitive electronics, so before starting work, it is recommended to remove synthetic clothing and touch the grounded metal object, this simple action will help to avoid unpleasant surprises after assembly.
💡
Use a magnetic mat or a piece of paper with squares drawn, marking where each screw is drawn. In Xiaomi smartphones, the screws can be of different lengths, and entanglement of places to install them can damage the motherboard.
Features of the design of Redmi 6
Understanding how the device is built from the inside makes it much easier to disassemble. Xiaomi Redmi 6 has a classic budget-friendly design with a non-removable back cover, which means that the panel is not removed by a simple movement of the hand, but is fixed to many hidden latches around the perimeter of the body.
The main material in the case is polycarbonate, which is flexible enough, but fragile when bending, and it has a metal frame attached to it, and it has access to the main components, such as the battery and plume connectors, when the back plastic panel is removed, and the screen stays in place, reducing the risk of damage from careless actions.
⚠️ Warning: Do not try to pull the lid on the side of the volume buttons or the charging connector. These areas contain plumes and antenna modules that are very easy to damage with a metal tool.
The panel is mounted exclusively on plastic clips that fit tightly into the slots of the main frame, with minimal or no adhesive layer used in this model, making it easier to reassemble, but the density of the latches requires a certain amount of effort to be controlled to avoid breaking the latches.
Inside the case, you'll see a large battery that takes up almost half the volume, and a main board at the top, and all the connections, including the display plume and the battery, are protected by metal plates that also require screws to be unscrewed, which provides additional protection from vibrations and shocks.
Step-by-step: how to remove the back cover
The dismantling process should begin with the device turning off. This is a critical condition, since accidental closure of the contacts of the switched on smartphone can short-circuit and failure of the power controller. After turning off, carefully inspect the ends of the device for visible screws - in Redmi 6 they are not on the external surface.
Find a small notch or recess in the bottom corner of the back panel, usually located closer to the USB connector. This is where you need to insert the thin edge of the mediator or plastic blade. Do not use metal objects at this stage if there is a risk of hitting the screen or internal components through the slit.
Follow the algorithm for safe opening:
- 👉 Insert the tool into the notch and rotate it gently to create the initial gap between the lid and the frame.
- 👉 Move the blade along the long side of the body, sliding the latch opening in a sliding motion. You'll hear a characteristic click.
- 👉 Repeat the procedure from the opposite side, gradually freeing the device perimeter from the locks.
- 👉 After all latches on the sides are freed, carefully bend the upper and lower parts of the cover.
Don't pull the lid up until you're sure it's not hooked anywhere. Sometimes there may be hidden locks in the area of the camera or the speakers. Movements should be smooth, without jerks. If the lid doesn't lend itself, it's better to walk the perimeter again than to use force.
☑️ Check before removing the lid
Access to internal components
Once you successfully remove the back, you'll be able to access the insides of your smartphone, but it's too early to take the battery out or disconnect the plumes, and the motherboard and battery connectors are often covered with decorative plastic pads or metal screens that are mounted with screws.
In the Xiaomi Redmi 6, under the back cover, you'll see a black plastic frame surrounding the perimeter and a central part covering the top area of the board. To get full access, you need to unscrew all the visible screws that hold these elements, which are usually 10 to 15 pieces, and they can be of different lengths.
Here are the main elements that become available after removing the protective screens:
- 🔋 Battery plume connector - located at the bottom of the board, requires careful disconnection.
- 📱 Display plume - wide connector, often covered with a metal plate.
- 📡 Antenna modules – contact areas that can be pressed with a lid.
- 🔊 Dynamic and vibrator - located in the lower part of the body, can have their mounts.
When working with internal components, avoid touching the contacts of connectors and open areas of the board. Fat traces can oxidize over time, which will lead to unstable operation of the device. Use tweezers with dielectric linings to manipulate small parts.
⚠️ Attention: The main camera plume in Redmi 6 is quite short and fragile.Be extremely careful when lifting the protective plates so as not to damage or tear it out of the connector.
What to do if the screw does not turn out?
Table of the main components and their location
So for the convenience of navigating inside the enclosure and understanding the interconnections between the elements, we've created a composite table that will help you navigate faster which component is responsible for what and where it is relative to other parts.
| Component | Location. | Firming | Features |
|---|---|---|---|
| Battery | Lower part of the hull | Glue strip + connector | Only after the sleeves have been removed. |
| Maternity fee | Top third of the hull | Screws + plumes | Closed by a metal screen |
| Main camera. | Upper left corner (back) | Module screws | Requires care when removing |
| Dynamician | Lower right corner | Screws + contact pogo pins | It is important to combine contacts correctly. |
Knowing the exact location of the components avoids chaotic actions, for example, knowing that the speaker is in the corner, you will not try to reach it through the middle of the case, and the table helps to identify the screws: long usually go to the frame, and short — on the board.
If you build it back, you'll be guided by this circuitry. If you don't fit even one component, like a speaker, you can have the lid sticking around or hanging around, and each element has to lie in its own landing plane.
Assembly of the device and verification of functionality
The Xiaomi Redmi 6 build process is done in reverse order relative to disassembly. Start by putting all the internal components in their places and connecting the plumes. Make sure that each connector is inserted before the characteristic click and fixed with a pressing plate, if it is provided by the design.
Once all the internal modules are connected, you can start installing the back cover. You can combine the lid projections with the grooves of the body around the perimeter. You can press evenly, moving from center to edges, so that the latches enter their sockets without skewing. The characteristic crunch of plastic is normal, but it should not be too loud or accompanied by cracking.
Before the final fixation of all screws, conduct an initial performance check:
- 📱 Turn on your smartphone and check the touch screen reaction.
- 🔊 Play the sound to make sure the speaker is working.
- 📷 Take a test photo on the front and main camera.
- 🔌 Connect the charger and check the charge indication.
If all the functions are working correctly, you can twist all the screws completely. Don't pull them over, the plastic can crack. Just feel the moment of thrust. Then wipe the case from the fingerprints and install it. SIM-map.
💡
The basic principle of assembly is not to force the joints, and if the part does not fit in, it means that it is installed incorrectly or another element interferes.
