How to remove the back cover on Xiaomi Redmi Note: instructions with photos and tips

Removing the back cover on Xiaomi Redmi Note smartphones is a challenge that owners face when replacing the battery, repairing the camera or cleaning up the dust. Despite the apparent simplicity, the procedure requires care: improper actions can damage latches, plumes or even the display. In this article, we will understand how to remove the cover on different generations of Redmi Note (from Note 4/4X to Note 12 Pro+), what tools you will need and how to avoid typical errors.

It's important to remember that the design of the case has changed over time: early models (before the Note 8) had removable clip-tops, and modern smartphones (beginning with the Note 9) were solid cases glued around the perimeter. We'll describe both options in detail, and we'll give you tips on how to choose tools and prepare the workplace. If you've never taken your phones apart, don't worry: with the right approach, even a beginner can cope in 10-15 minutes.

Preparation: security tools and measures

Before you start disassembling, make sure you have everything you need. The minimum set of tools includes:

• 🔧 Plastic blade (or mediator) - for putting the cover without scratches.
• 🔨 Thin screwdriver (cross or five-pointed, depending on the model).
• 🧲 Magnetic substrate or screw box – so as not to lose small details.
• 🔥 Hair dryer (for models with glue fastening) - heating helps soften the glue.
• 🧴 Isopropyl alcohol (90%+) — glue-cleaner.

If you are working with a Redmi Note 10/11/12 model, where the lid is glued, you will additionally need a screen suction cup (you can use from older smartphones). For the Redmi Note 8 Pro and older, a needle or a paper clip will be useful - they are convenient to put a protective film under the lid.

⚠️ Warning: Do not use metal blades or knives - they leave scratches on the plastic and can damage the plumes. Also avoid overheating with a hair dryer: temperatures above 60°C can deform plastic or damage the battery.

Before disassembling, be sure to turn off the smartphone and remove SIM-A memory card (if installed) and a clean, well-lit surface, so you'd better cover the table with a soft cloth so you don't scratch the screen.

Removal of the cover on older models (Redmi Note 4/4X, Note 5/5A, Note 6 Pro)

Redmi Note 4-6 smartphones have a removable back cover that attaches to plastic latches, which makes it easier to access the battery and slots, but requires caution: the latches are fragile and can break when pressed hard.

Step-by-step:

1. Put the phone down on a soft surface.
2. Find the gap between the lid and the body – it is usually visible at the charging connector or speaker.
3. Put a plastic blade in the slot and gently lead along the edge, snapping the clips. Start at the bottom corner, there's a smaller latch.
4. When the lid begins to move away, do not pull it sharply: plumes may be glued under it (for example, the Note 5 has a fingerprint scanner plume).

If the lid doesn't lend itself, check to see if the clips on the top (near the camera) are unlatched. On the Note 4X and Note 5A, you sometimes have to put in a little more effort - that's fine, but don't overdo it.

⚠️ Warning: The Redmi Note 6 Pro has a metal plate attached to the screws under the lid. Don't try to remove it without a screwdriver, it can damage the antenna contacts.

Disassembly of modern models (Redmi Note 7-12): work with adhesive fastening

Since the Redmi Note 7, Xiaomi has moved to single-body housings where the back cover is glued around the perimeter, making it harder to disassemble, but making the structure more durable.

Algorithm of action:

1. Heat the edges of the cover with a hairdryer for 1-2 minutes, keeping it at a distance of 5-7 cm. Start at the bottom (near the USB-C connector).
2. While the glue is softened, suction the lid closer to the bottom edge and pull up. If there is no suction cup, use a plastic spatula.
3. When a gap appears, insert a spatula or a mediator into it and slowly lead along the edge, separating the glue. Be careful at the camera and antenna lines - there are plumes!
4. After removing the lid, clean the glue residues with isopropyl alcohol. A new adhesive (such as B-7000) will be needed for reverse assembly.

On Redmi Note 10 Pros and later, there may be a battery-operated protective film under the lid. Don't unnecessarily remove it, it prevents short circuits. If the film is torn, replace it with a new one before assembly.

💡

If the lid does not go away even after heating, try using a thread or guitar string: slash it under the lid and "saw" the glue, gently moving the thread along the edge.

Frequent Mistakes and How to Avoid Them

Even experienced users sometimes make mistakes when disassembling the Redmi Note, and here are the most common problems and ways to prevent them:

• 🔧 Broken latches -- they occur when you pull the lid unevenly. Solution: Click the clips one by one, starting with the corners.
• 🔥 Battery overheating, if you heat it with a hair dryer for too long. Solution: heat it to 50-60°C (should be warm but not hot).
• ⚡ Damage to the fingerprint scanner plume - typical for Note 9/10. Solution: Before removing the lid, check if there is a glued plume under it.
• 📱 Scratches on the screen -- they appear when you put your phone down on a hard surface with your screen.

On the Redmi Note 8 Pro and later, there is a metal plate under the lid that is attached to 5-7 screws. If you do not remove it before dismantling the battery, you risk breaking the plumes or tearing off the antenna contacts.

Another common mistake is to use the wrong glue when you build it, so don't take superglue or Moment, they can damage the plastic, and the best option is a B-7000 or a 0.2 mm double-sided 3M tape.

How to put your phone back together: tips for gluing

Building a Redmi Note after repair is as important as disassembling, and if you stick the lid in the wrong way, it will move away or creak. Here's a step-by-step algorithm:

1. Clean the edges of the case and the lid of the old glue with isopropyl alcohol.
2. Apply a thin layer of B-7000 glue around the perimeter of the body (don’t skimp, but don’t overdo it either – excess can come out).
3. Carefully press the lid, starting at the bottom edge, make sure all latches are in place.
4. Place the phone under a press (for example, between two books) for 10-15 minutes.
5. Do not turn on the smartphone for 1-2 hours to the glue is completely dry.

For Redmi Note 11/12 models with double-sided tape instead of glue, the process is slightly different:

• Cut the scotch on the shape of the lid, leaving a drop of 1-2 mm.
• Stick the tape to the case, then remove the protective film and press the lid.
• Roll the edges with a roller or finger for better grip.

⚠️ Warning: After gluing, check if the lid interferes with wireless charging (if supported.

💡

For reliable fixation of the cover, use a combination of glue B-7000 and bilateral tape: apply glue around the perimeter, and scotch in the center (under the battery).

Models with unique features: Redmi Note 8 Pro, Note 10 Pro, Note 12

Some Xiaomi smartphones have design nuances that you should know about in advance.

Redmi Note 8 Pro:

• Under the lid is a metal plate, which is attached to 7 screws (five-pitched screwdriver).
• The fingerprint scanner plume is glued to the board - gently disconnect it before removing the plate.
• Antenna contacts are very fragile - do not pull them when dismantling.

Redmi Note 10 Pro:

• The cover is attached to the glue + 2 screws under plugs (near the USB-C connector).
• There is a protective film on the battery under the lid - do not remove it unnecessarily.
• The camera protrudes above the body - when heated with a hairdryer, do not direct the airflow to it (the plastic of the lens can melt).

Redmi Note 12 Pro+:

If you're disassembling a Redmi Note 12 with a factory film on the screen, be careful: when heated with a hairdryer, it can peel off. It's better to remove it beforehand or protect it with paint tape.

When is the best time to contact the service center

Although removing the back cover on the Xiaomi Redmi Note is a task feasible for most users, in some cases it is better to trust the professionals.

• 🔧 You have never taken your phone apart and are afraid of damaging the plumes.
• 📱 The cover cracked, and need its replacement (in the service will pick up the original detail).
• ⚡ After disassembly, the phone does not turn on or artifacts appeared on the screen.
• 🔋 Requires a battery replacement, and you are not sure about your soldering skills (on some models, the battery plume is soldered).

The cost of removing/installing a lid in the service is usually 300-800 rubles, depending on the model. If you damage the plume or the fee, repair can cost 1500-5000 rubles. So weigh the risks: if the phone is expensive (for example, Redmi Note 12 Pro+), it may be better not to experiment.

In Moscow and St. Petersburg, Xiaomi’s official service centers offer warranty repairs (unless the phone is warranty-free and disassembled), but self-opening the case usually voids the warranty – be aware of this before you start work.

💡

If you're disassembling a battery replacement phone, buy an original battery with a capacity that matches the model, and cheap ones can swell or fail quickly.
