Xiaomi Redmi 6 is a popular budget smartphone that is still in use today for its reliability and low price. However, over time, even such devices require repairs, from replacing the battery to cleaning the connectors or recovering from a fall. Disassembly of Redmi 6 is not the most difficult task, but requires accuracy and knowledge of the key points.
In this article, you will find a step-by-step photo instruction, a list of tools you need, and critical warnings to avoid typical errors. We will examine not only the standard procedure, but also the nuances associated with a particular model - for example, how to properly disconnect the battery plume or not damage a fragile display module.
If you've never taken a smartphone apart before, don't worry: Redmi 6 is a great first-time experience, just follow the instructions and take your time, and if you're in doubt, you better go to the service center.
Preparation for disassembly: tools and safety
Before you start, make sure you have everything you need, and that lack of tools or inadequate preparation is the main cause of damage during the disassembly.
- 🔧 Plastic blade (or mediator) - for careful putting of the lid and plumes.
- ⚙️ Cross screwdriver (size) PH00 or PH0) — for screws in Redmi 6.
- 🔥 Hair dryer or thermal air station - to soften the glue under the back cover (optional, but recommended).
- 🧲 Magnetic mat or container – to avoid losing small screws.
- 📱 Screen suction cup - will help to gently lift the display module.
- 🔋 Tweezers – for working with small details, for example, plumes.
Also, prepare your workspace: it should be well lit, clean and without static electricity (ideally an antistatic mat). In Redmi 6, the battery plume is soldered to the motherboard, so you can't just turn it off, which is a key point that many people miss. If you're not ready for soldering, you better not take risks and leave it to the professionals.
⚠️ Warning: If you're disassembling a smartphone with a broken screen, be sure to stick tape on it so that the shrapnel doesn't hurt your hands or get inside the case. Also be careful with a lithium-ion battery - damage to it can lead to a fire.
Step 1: Removing the back cover
The back cover of Xiaomi Redmi 6 is attached to glue and latches. To remove it, act as follows:
- Turn off your smartphone and remove it. SIM-card and memory card (if installed).
- Heat the back cover with a hair dryer (~60°C) for 1-2 minutes to soften the glue. Don't overheat - this can damage the plastic!
- Insert a plastic blade into the gap between the lid and the body (start at the bottom edge where the charging connector is). Carefully drive the blade around the perimeter, snapping the clamps.
- As soon as the lid begins to give in, do not pull it sharply - raise it by 1-2 mm and check if all the latches have disconnected.
If the lid doesn't lend itself, warm it up again with a hair dryer. Don't use metal tools, they'll scratch the body and damage the interior parts. In Redmi 6, the back cover is quite fragile, so act as carefully as possible.

When you take the lid off, you'll see the battery, the motherboard, and the plumes. Don't touch the chips on the board, static electricity can damage them. If you're disassembling a smartphone to replace the battery, remember, in this model, it's soldered to the board, and you'll need soldering to replace it.
Step 2: Turn off the battery and plumes
Before you continue, be sure to turn off the battery. In Redmi 6, this is done outside the box:
- 🔌 The battery is soldered to the board, so you can't just disconnect it. If you need to de-energize the device, carefully unplug the red and black wires from the contacts (this will require a soldering iron with a thin sting).
- 📶 Turn off antenna plumes (they are attached to the top of the board) and the plume of the display module (located under metal protection).
- 🔊 Disconnect the plume speaker and vibromotor (they are in the lower part of the body).
If you're not planning on soldering, you can just bend the battery plume gently to the side so it doesn't get in the way, but remember, any careless movement can tear the contacts off, and then you can't do without soldering.
| Trail/detail | Location | Method of shutting down |
|---|---|---|
| Battery | Center of the hull, under the payroll | Sweater (disconnect + and -) |
| Display module | Under metal protection | Click the connector with a plastic blade |
| Main camera. | Top of the pay | Unscrew 2 screws, unplug the plume |
| Dynamician | Lower left corner | Disconnect the connector, unscrew 1 screw |
⚠️ Note: If you accidentally damage the display plume, the smartphone may stop responding to touch or not turn on at all. 1/3 The cost of the new Redmi 6.

Step 3: Dismantling the motherboard
The Redmi 6 motherboard is mounted on multiple screws and double-sided tape to extract it.
- Unscrew all the screws (about 10-12 pieces) with a cross screwdriver. Remember the location of the screws of different lengths, when you assemble them, you need to return them to their places.
- Carefully tuck the board with a plastic spatula. Start at the edge where there are no connectors.
- If the fee is not amenable, warm it up with a hair dryer (not higher than 70 ° C) to soften the scotch.
- After removing the board, place it on an antistatic surface.
At this point, you'll have access to all the key components: the processor, memory, communication modules, and if your goal is to replace the charging connector or the microphone, you can now do it without the risk of damaging the board.
💡
Before you unscrew the screws, take a picture of their location on the board. This will help to avoid confusion during the assembly, especially if the screws are of different lengths.
Step 4: Disassembly of the display module
Redmi 6's display module is made up of multiple layers: glass, sensor, LCD. If you just need to replace glass, you can do without completely disassembling, but replacing the matrix or plume will require dismantling the entire module.
Algorithm of action:
- Remove the metal protection that is attached to 4 screws.
- Disconnect the display plume (it is fixed with a latch - carefully tuck it with a spatula).
- Warm up the edge of the display with a hairdryer (temperature ~50 ° C) - this will help soften the glue.
- Use a suction cup to gently lift the module. Don't pull it sharply - plumes pass under the display!
If the display cracks, be very careful: the shrapnel can injure the hands, and also damage the plumes when sloppy movement.

Step 5: Replace the battery (for experienced)
Replacing the battery in Xiaomi Redmi 6 is one of the most difficult procedures because of soldered contacts. If you can't solder, you better trust the professionals.
- 🔥 Heat the board around the contacts of the battery with a hairdryer (temperature) ~200°C) - this will help melt solder.
- 🔧 Carefully tuck the contacts with a soldering iron with a thin sting and disconnect the wires.
- 📦 Remove the old battery (it is attached to double-sided tape). Be careful not to puncture it!
- 🔄 Install a new battery, solder contacts and secure with tape.
After replacing the battery, be sure to check its operation: connect the charger and make sure that the smartphone is charging normally. If the battery is swollen or deformed, do not use it - it is dangerous!
⚠️ Warning: When soldering the battery, do not overheat the charge - this can damage nearby chips. If you have never soldered before, practice on an unnecessary fee or contact the service.
Step 6: Build a Smartphone
The Redmi 6 is being built in reverse order, but there are a few key points:
- 🔩 Make sure all screws are screwed into their places.Sharps of different lengths should not be confused - this can damage the board.
- 📶 Check that all the plumes are tightly connected and fixed with latches.
- 🔋 If you have soldered off the battery, check the soldering quality again before turning on.
- 🔍 Before the final assembly, turn on the smartphone (without the back cover) and check the operability of all modules: camera, speaker, sensor, charging.
Once assembled, turn on the phone and test it. If something doesn't work (e.g., sensor doesn't respond or camera doesn't turn on), take it apart again and check the plumes' connection, most often because of poorly connected connectors or damaged plumes.
💡
The most common build error is loosely connected plumes. Always check for latches, or your smartphone may not turn on or malfunction.
Frequent Mistakes and How to Avoid Them
Even experienced craftsmen sometimes make mistakes when disassembling Redmi 6, and here are the most common ones and ways to prevent them:
| Mistake. | Effects of consequences | How to avoid |
|---|---|---|
| Use of a metal blade | Scratches on the body, damage to plumes | Use only plastic or wooden tools |
| Overheating of the fee by a hairdryer | Detachment of chips, failure of modules | Do not heat above 70°C, use thermal control |
| Confusion with screws | Damage to pay, unstable work | Put the screws in groups or photograph their location |
| Sharp tearing of the display | Trail break, cracks in the matrix. | Warm up the glue and use the suction cup |
If you make a mistake, don't panic. Most of the time, you can fix it. For example, if the plume comes off, you can solder it back (though it's going to take soldering experience to do that), and if you damage the body, you can replace the back cover, which is inexpensive.
