Preparation for disassembly: what you need to know before the beginning
Disassembling the Xiaomi Redmi 6X (codenamed wayne) is a task that requires accuracy and the right tools. This budget device, released in 2018, has a classic design with a removable back cover, but even here there are nuances. Before you start, make sure you understand the risks of self-repair: loss of leakage, damage to plumes or failure of warranty (if it is still valid).
The main reasons why users disassemble the Redmi 6X are:
- π Replacement of the battery (capacity 3010 mAh, type) BL47)
- πΈ Repair or cleaning of the chamber (the main module 12 MP) + 5 MP)
- π Replacement of speaker or microphone
- π οΈ Diagnosis after falling or getting moisture
If your goal is to replace the battery, consider that the original batteries for this model have already been discontinued, but analogues from proven brands (for example, Baseus or Remax) will do. Other types of repairs may require a soldering station or a multimeter - without the skills to work with them, it is better to contact the service.
Tools required: a complete list with explanations
You'll need a minimal set of tools to disassemble the Redmi 6X, but each one is important.
| Tool. | Appointment | Where to Buy/Alternative |
|---|---|---|
| Plastic spatula (suction cup) | Rear cover compartment without scratches | AliExpress, tool shops |
| Cross screwdriver PH00 | Turning the screws of the motherboard | Any set of electronics |
| Tweezers with curved ends | Disconnection of plumes and small parts | Radio shops |
| Thermoclei or bilateral scotch | Fixing the battery after replacement | Household shops |
| Isopropyl alcohol (90%+) | Cleaning contacts from oxidation | Pharmacies, electronics stores |
β οΈ Warning: Do not use metal blades or knives to separate the lid, it is almost guaranteed to damage the plastic latches. If you do not have a plastic blade, you can use a guitar transmitter or a bank card (but accuracy will have to double).
Also prepare the workplace:
- πΈ Lighting: bright lamp or flashlight (better with a magnifying glass)
- π§² Organizer for screws: magnetic mat or container with cells
- π Antistatic bracelet (optional, but recommended when working with a board)

Before disassembling, take a picture of the location of all the plumes and screws - this will greatly simplify the reverse assembly.
Step-by-step: how to remove the back cover
So, the most important thing to start with is the detachment of the back, and in the Redmi 6X, it's mounted on the latches and glue, so you have to be smooth, but you have to be confident.
- Turn off the phone and remove the tray for SIM-cards (use a paper clip or special key).
- Heat the edges of the cover with a hair dryer (50β60Β°C) for 1-2 minutes. This will soften the glue. Don't overheat - the plastic can deform!
- Insert a plastic blade into the gap between the lid and the body (start with the lower left corner where the charging connector is located).
- Carefully drive the shoulder blade along the edge, alternately snapping clips, about 12 to 14 of them.
- When the lid is separated, do not remove it completely - it is connected to the fingerprint scanner plume!
β οΈ Warning: If the lid doesn't respond, don't force it. You probably missed the latch or didn't warm up enough. Reheat and try again.
After the lid is removed, you will see:
- π Battery (stick to the body)
- π± Motherboard (closed by metal screen)
- πΈ Double camera module (fixed on board)
- π Dynamic and vibrator (lower part)
βοΈ Check before continuing disassembly
Disconnection of the battery and plumes: safety
Before touching the motherboard, be sure to turn off the battery. Even when it is off, it can cause a short circuit when in contact with metal tools.
- Put a plastic blade on the battery plume and gently disconnect it from the circuit board connector. Use tweezers if your fingers are uncomfortable.
- Check the voltage on the contacts of the battery multimeter (should be 0 V).
- If the battery is blown, don't try to puncture it, it could cause a fire. Dispose of it according to local regulations.
Then disconnect the other plumes:
- π± Main display plume (located under metal screen)
- πΈ Camera plume (thin, easily torn!)
- π Dynamics and microphone plume
β οΈ Attention: Trains at Redmi 6X They're fragile, especially in the camera. If you feel resistance to disconnect, don't pull them by force, check if there are any additional latches.

Motherboard extraction and component diagnostics
The Redmi 6X motherboard is mounted on 8 screws of different lengths, and remember the location of each one, because when you build the long screws, you don't have to touch the board, or you risk damaging the tracks.
- Unscrew all the screws and remove the metal screen (it acts as a heat sink).
- Then, turn the left side of the sleeve and put it on the right side.
- Check availability fee: π₯ Burned components (especially around the Qualcomm Snapdragon 625 processor) π§ Traces of corrosion (green plaque on contacts) π Logs torn off (often after falls)
Typical problems with the Redmi 6X board:
- πΆ It's not working. SIM-map: check the slot contacts and soldered connections.
- π Fast discharge: often the fault of the power controller (PM8941).
- π΅ No network: It may be damaged RF-booster (QFE1100).
If you're not sure about your brazing skills, you should trust the board's diagnostics to professionals, for example, replacing the power chip will cost between 1500 and 3000. β½, But self-repair without experience often leads to complete loss of the device.

The motherboard is the most expensive component of the phone. If you're not sure about your abilities, limit yourself to replacing the battery or speaker.
Replacement of the battery: Step-by-step with a photo
Redmi battery 6X (model BL47) It loses capacity over time, especially if the phone has often run out of capacity. It costs 800-1500 to replace. β½, But with care, it can be done on its own.
- Unplug the old battery with a plastic spatula. If the glue is too strong, use isopropyl alcohol to soften.
- Clean the seat of glue and dust residue. Check the contacts on the board, they should be clean.
- Stick the new battery onto double-sided tape or heat-glue. Don't use superglue!
- Connect the battery plume to the board and check the voltage with a multimeter (should be ~3.7-4.2 V).
β οΈ Warning: After the battery is replaced, the phone may not turn on. This is normal - sometimes you need to recharge for 10-15 minutes before the first turn on.
Tips for choosing a battery:
- π Original batteries (if you find them) are the best choice, but they are rare.
- π Analogues from Baseus or Remax - optimal price/quality ratio.
- π« Avoid βenlargedβ batteries (e.g., 4,000 mAh) β they are often incompatible with a charging controller.
Phone Assembly: How to Avoid Mistakes
The Redmi 6X should be built in reverse order, but there are a few critical points:
- Check all the plumes -- they should be tightly inserted into the connectors. The camera plume is particularly capricious.
- Tighten the screws cross-cross to avoid skewing the board.
- Test your phone in stages: π First plug in the battery and check the charging. π± Then plug in the display and check the sensor. πΈ Last but not least, the camera and speaker.
β οΈ Warning: If the phone doesn't turn on after assembly, but when you connect to charging, it shows an indication, the problem may be the power plume or battery contacts.
Frequent errors in assembly:
- π§ Forgotten screws under metal screen (lead to poor antenna contact).
- π± Clutched display plume (causing "dead zones" on the screen).
- π Unconnected speaker (sound will be quiet or absent at all).

Once assembled, be sure to check all the phone's features: calls, camera, sensor, Wi-Fi. If something doesn't work, disassemble the device again - most likely, there's a connection error somewhere.
