Xiaomi’s Redmi line of smartphones has earned a reputation for being affordable and reliable, but over time, even they require technical intervention. The Xiaomi Redmi 6 may need to be disassembled for various reasons, from replacing a broken display to installing a more capacious battery or cleaning the dust connectors. It is important to understand that opening the case is a responsible process that requires accuracy and a minimum set of tools.
Unlike the flagship models, the Redmi 6 is relatively simple, but has its own features of attaching plumes and rotor arrangement. Wrong actions can damage internal components, so before starting work, you need to study the device from the inside. In this article, we will look at each stage of dismantling in detail so that you can safely perform repairs at home.
Preparation of the workplace and tools
Before disassembling the case, you need to organize a comfortable workspace, the surface should be clean, flat and well lit so that the small details are not lost and are clearly visible. It is recommended to use an antistatic mat or just a clean fabric, so as not to scratch the back cover of the smartphone during operation.
To do this successfully, you'll need a specific set of tools that can be problematic to open Redmi 6, such as a suction cup to lift the back panel, and a set of plastic mediators to snap latches, which are highly undesirable because they can easily damage fragile plumes or break through the battery.
- 🔧 Set of screwdrivers (mandatory presence of cross-haired) PH000 flat)
- 📱 Plastic suction cup for lifting the back cover
- 🛠️ Plastic blades (mediators) for opening the body
- 🧲 Magnetic mat or screw sorting container
- 💨 A hair dryer or thermophen to soften glue
Particular attention should be paid to safety when working with a lithium-ion battery. If you notice a bloating battery during the disassembly process, further work should be carried out with the utmost care, avoiding punctures. Also, before starting any manipulations, make sure that the device is turned off to exclude short circuit on the board.
☑️ Ready for repair
Rear cover removal and primary access
The process of disassembling the Xiaomi Redmi 6 begins with removing the back panel, which in this model is attached to glue and plastic latches around the perimeter. First, you need to carefully warm the perimeter of the cover with a hairdryer, setting a temperature of about 80-90 degrees. Don't hold the hairdryer too long at one point, so as not to overheat the display matrix or the plastic of the case.
After warming up, insert the suction cup into the bottom of the back cover, closer to the logo, and slightly pull up to create a gap. Insert a plastic spatula gently into the resulting gap and guide it along the faces, gradually snapping the locks. The movements should be smooth, without sharp jerks, so as not to break the plastic ears of the attachments.
⚠️ Warning: Do not try to cover the corners immediately after heating, there are plumes and components that can be damaged by careless movement of the tool.
When all the latches around the perimeter are freed, you can remove the back panel completely, and you can access the insides of the smartphone, where you can immediately see a large battery and a protective plastic bar, and at this point, it is important to take your time and inspect the insides for visible damage or oxidation.
What to do if the lid is not removed?
Removal of the protective bar and disconnection of plumes
When you remove the back cover, you'll see a black plastic bar covering the motherboard's main connectors and mounts, and it's fixed by a few screws that you need to unscrew, and it's important to remember the location of each screw, because they can have different lengths and threads, which is critical when you build them back.
Under the bar are the display plumes, touchscreen, main and front cameras, and the connectors of the buttons and connectors. Before removing any modules, you need to turn off the battery. This is the most important step in the entire instruction, since the power outage prevents short circuits when working with other components.
To turn off the plumes, use a plastic blade or finger, gently lifting the connector upwards. Don't pull the wires themselves, the impact should only be on the hard part of the connector. Once the battery is turned off, you can safely remove the remaining modules, including the main control unit.
| Component | Location. | Type of attachment | Features |
|---|---|---|---|
| Battery | Central part | Glue + connector | Requires heating to remove |
| Maternity fee | Upper part | Screws + plumes | Lots of small contacts. |
| Main camera. | Upper left corner | Landing place | Fragile lens |
| Dynamician | The bottom part | Screws + pinch | It has a rubber sealer. |
💡
Always turn off the battery first, even if you plan to change only the speaker or camera to avoid fatal errors.
Removal of the battery and replacement of components
Replacing the battery in Redmi 6 is one of the most common causes of disassembly, as over time, the capacity decreases. The battery is glued into the case with double-sided tape, so to extract it, you will need to reheat the bottom of the device. Be careful: deformation or puncture of the battery can lead to fire.
Use a plastic card or a special spatula to poke the edge of the battery and slowly separate it from the body. The movements should be progressive, try not to bend the battery. If the old cell sits very tightly, you can use isopropyl alcohol by dripping a couple of drops under the edge to dissolve the glue.
Once you remove the old cell, install the new battery by applying a fresh layer of glue or double-sided tape to hold it together. Connect the battery plume to the motherboard before you click, making sure it's up straight. You can now test the device's performance without collecting it completely by turning it on for a short time.
- 🔋 Check the voltage of the new battery with a multimeter before installation
- 🧴 Use a special glue B-7000 battery-lock
- 🧤 Work with gloves so that the fat from the fingers does not get on the contacts
- 👀 Visually inspect the new battery for swelling
If you change other components, such as the display module or the charging connector, the algorithm of actions is similar: disable the old plume, carefully remove the part and install a new one in its place. When installing the screen, it is important to check whether there are dust particles under the protective glass, since it will be impossible to remove them after gluing.
Withdrawal of motherboard and cameras
Deep repairs, like replacing the USB Type-C charging connector or repairing the audio codec, may require the motherboard to be fully removed. It is mounted with multiple screws and is held on to plumes that we've already disabled in previous stages. Carefully unscrew all the visible screws holding the board.
Notice the antenna contacts (spring-loaded pins) that press the board against the case or connect it to the antennas. When lifting the board, they must be carefully removed or monitored so that they do not bend. The Xiaomi Redmi 6 motherboard is compact enough, but full of small elements that require careful care.
⚠️ Attention: Motherboard is the most expensive component, and avoid static electricity by running on an antistatic mat.
The cameras in this model are held tightly enough in their seats, the main camera can have an additional lock or a pressing plate, and when you remove the camera module, take it over the side edges, trying not to touch the lens with your fingers, because it is difficult to remove greasy traces without indiscriminately removing the module itself.
💡
When you reset the camera, make sure that the protective film is removed from the lens, otherwise the photos will be cloudy and blurry.
Assembly of the device and verification of functionality
The Redmi 6 is assembled in reverse order, but there are some nuances. Before you screw and glue the lid, you need to do an initial check of all the replaced nodes. Turn on your smartphone and check the touchscreen, sound, microphone, vibrator and charging.
If all functions are working correctly, you can proceed to the final fixation. Apply a thin layer of glue B-7000 or a special sealant around the perimeter of the middle frame (not on the lid itself or on the board!). Carefully attach the back panel and press it around the perimeter, fixing with rubber bands for 15-20 minutes before grasping the glue.
When you twist the screws, keep the sequence: first the angular, then the central, but do not tighten them to the end at once. Walk through all the screws again after the initial fixation to ensure that the board fits evenly. Excessive force can lead to the failure of the thread in the plastic case.
- ✅ Check the operation of all sensors (approach, light)
- ✅ Make sure there is no gap between the screen and the frame.
- ✅ Test communication modules (Wi-Fi, Bluetooth, 4G)
- ✅ Check the heating of the device in standby mode
Complete cooling of the glue takes about 24 hours, so on the first day do not expose the smartphone to extreme loads or moisture. Properly assembled device will serve you faithfully, prolonging the life of the popular model.
