Xiaomi Redmi 4X
Redmi 4X is relatively easy to understand.
Many users are afraid of damaging latches or plumes, especially if they have not previously had experience disassembling equipment. This article will help avoid the typical mistakes: here you will find a step-by-step photo instruction, a list of necessary tools, and safety tips. We will also analyze how disassembling the 32GB version differs from other versions of the Redmi 4X (for example, 16GB or 64GB) and what “pitfalls” can wait while working.
If you’re planning to replace your battery or repair your smartphone yourself, remember that in the Redmi 4X, the back cover is attached to plastic latches, not glue, but if you open them sloppy, they can break, a key difference from newer Xiaomi models, which often use adhesives.
Preparation for disassembly: tools and security measures
Before you start opening the lid, make sure you have everything you need. Wrong tools are the main cause of damage to the body or internal components.
- 🔧 Plastic blade or mediator (thickness 0.5-0.7 mm) - for snapping the lid without scratches.
- 🧲 Suction (optional) – helps to lift the cover after heating, if the latches are too tight.
- 🔥 Dryer or thermal air station - for softening the glue (if the cover was previously glued after repair).
- 📦 The screw container - at Redmi 4X 8 screws of different lengths are used, they are easy to confuse.
- 🧴 Isopropyl alcohol (70%+) — Cleaning contacts if you plan to clean the board.
Important: If you're disassembling your smartphone for the first time, take a picture of each step, which will help you put it back together correctly.
- 🚫 Do not disassemble your smartphone on a carpet or soft surface – screws and small parts are easy to lose.
- 🌡️ The temperature in the room should be 20-25°C: Cold plastic becomes brittle.
- ⚡ Turn off your phone and remove the SIM cards. + Memory card (if any) Do not remove the battery until the plumes are completely turned off!
⚠️ Attention: If your Redmi is 4X I've been through repairs before, the lid could have been glued, and in this case, you can't do without a hair dryer heating -- but overheating over 60.°C will damage the display!
Step-by-step: how to open the back cover Xiaomi Redmi 4X 32GB
Now, let's get to the process, and follow the instructions in strict order, and that minimizes the risk of damage, and let's start with the body preparation.
1.Switch off the power: press the power button for 10 seconds to make sure the phone is off.If the battery is drained, plug the charge for 5 minutes - this will make it easier to retrieve the battery plume later.
2. Heat the edges of the lid (if it is glued): use the dryer at minimum power, keeping it at a distance of 10 cm. Warm each edge for 20-30 seconds. Do not direct hot air to the display!
3. Insert the blade into the gap: start at the lower right corner (near the charging socket). Press carefully to separate the first latch. You will hear a characteristic click.
4. Swipe the perimeter with your shoulder blade, slowly move the tool along the edge, snapping the latches one at a time. Don't try to pull the lid off by force! If you feel resistance, warm up the area again.
5 Lift the lid: when all the latches are snapped, gently lift the lid with a suction cup or fingers, and it should be removed effortlessly.
Inside, you'll see the battery, the motherboard and the plumes. Don't touch the board with your bare hands, static electricity can damage the chips.
☑️ Checklist before lid removal
What is the difference between the Redmi 4X 32GB and other versions?
Smartphone Xiaomi Redmi 4X was produced in several versions: 16GB, 32GB and 64GB. Externally they are identical, but there are nuances when disassembling:
| Modifications | Features of disassembly | Typical problems |
|---|---|---|
| Redmi 4X 16GB | The back cover is often glued from the factory | It is more difficult to separate without heating |
| Redmi 4X 32GB | The latches are more fragile, but there is no glue. | Risk of breaking latches with careless opening |
| Redmi 4X 64GB | Sometimes there is a reinforced fastening of screws | More durable screwdrivers may be needed. |
In the version 32GB There is no factory glue, which simplifies disassembly, but the latches are thinner than in the 64GB-If you bought a used phone, chances are that the previous owner has already opened it and used glue, in which case you can't do without a hair dryer.
Another caveat: in some Redmi 4X 32GB batches, the fingerprint scanner plume is glued to the lid, you can tear it off if you don't care, and before you fully separate the lid, check if the plume is stretching behind it.
⚠️ Warning: If you see that the fingerprint plume is torn after removing the lid, don't try to stick it yourself. In 90% of cases, this leads to the sensor being inoperable.

Common Mistakes in Disassembly and How to Avoid Them
Even experienced users sometimes make mistakes that lead to failure, and here are the most common ones and ways to prevent them:
- 🔨 Use of metal tools: mediators or knives scratch the body and can close contacts on the board.Always use plastic or wooden blades.
- 🔥 Dryer overheating: If you heat the lid for longer than 30 seconds in one area, you can melt the plastic or damage the display. Keep the hair dryer at a distance and move it constantly.
- 🔋 Removing the battery without turning off the plume: this can lead to a short circuit.Always disconnect the battery first!
- 📱 Strong pressure on the display: Redmi screen 4X is attached to the frame, and if you press on it when removing the cover, cracks may appear.
Another common problem is the loss of screws. The Redmi 4X uses 8 screws of different lengths:
4 short (fix the lid to the frame),
2 medium (fix the motherboard),
2 long (hold camera and vibrator).
If you confuse them when you build them, the board can warp and the camera can get out of focus. Use a magnetic mat or a container of cells to keep parts from getting lost.
💡
If the latch doesn't work, don't try to break it. Try to warm it up with a hair dryer again, or use a thinner blade. At the very least, you can gently stick the latch with a needle, but without fanaticism!
What to do after removing the cover: further actions
When the lid is successfully removed, you will see the inside of the smartphone, and here's what you can do next:
- 🔋 Battery replacement: unplug the battery plume (it's glued to the board), then gently tuck the battery in with a plastic card. 4X The glue is used, so it will take effort.
- 📸 Cleaning the camera: if the photos are cloudy, wipe the camera lens with a cotton swab soaked in isopropyl alcohol.
- 🧹 Dust Removal: Use a soft brush or compressed air can to clean the motherboard and connectors.
- 🔧 Replacement of speaker or microphone: These components are mounted on screws and are easily replaced when spare parts are available.
If your goal is to replace the battery, look at the model. The Redmi 4X 32GB uses a 4,100 mAh BM47 battery. When you buy a new battery, make sure it is the same capacity and has the original plume. Cheap analogues are often not compatible with Xiaomi's charge control system.
Once you've finished, check all the plumes and connectors before you assemble.
- The battery plume sits tightly in the connector,
- The fingerprint scanner's tail is not bent,
The screws are twisted with the right force (do not pull!).
💡
Before assembling your smartphone, always check to see if there are any foreign objects (screws, pieces of plastic) inside. Even a small motif under the battery can lead to a short circuit!
How to build Xiaomi Redmi 4X back: build tips
Building a smartphone after repair is no less important than disassembling. Here are the key points to pay attention to:
1. Rotor twisting: start with the long (camera and vibrator), then the medium (motherboard), and last of all the short (lid). Don't twist them "by eye" - use a screwdriver with a torque limiter.
2. Checking plumes: before closing the lid, turn on the phone (without installing the lid) and check:
- Is the sensor working?
- Does the SIM card system see,
- Does the fingerprint scanner work?
3. Install the cover: start at the top edge, then gently snap the sides. Don't press the center of the cover, it can damage the display. If the cover doesn't sit tight, check if the plume or dust is disturbing.
If the phone doesn't turn on after assembly, don't panic.
- Unconnected battery plume,
- Short circuit due to metal shavings,
Incorrectly installed SIM card (can block contacts).
In this case, disassemble the smartphone again and carefully examine all connections.
When to contact the service: signs of serious problems
While the Redmi 4X is relatively easy to disassemble on your own, there are situations where it is best to trust the professionals.
- 💥 After disassembly, the phone does not turn on, even if all the plumes are connected correctly.
- 📱 The display stopped responding to touches or appeared vertical stripes.
- 🔌 The battery quickly discharges or swells - this is a sign of a malfunction of the power controller.
- 📡 Antennas are not working (no network or Wi-Fi) – possibly damaged RF-plume.
Also, it is worth considering that in some cases, self-repair can deprive the warranty (if it is still valid).
If you are not confident in your abilities, but want to save money, look for services with a fixed price for disassembly. For example, for a replacement battery in the Redmi 4X charge from 500 to 1000 rubles (depending on the region).
⚠️ Warning: If you notice that the motherboard has traces of oxidation or burnt components, do not try to repair it yourself. This is a sign of a serious malfunction, and without special equipment (for example, a soldering station), repair is impossible.
