How to open the back cover on the Xiaomi smartphone: instructions with photos and videos

Replacing the battery, repairing the camera plume, or cleaning up dust are all tasks that every Xiaomi owner faces sooner or later, but the first and most important step in any such repair is removing the back cover. At first glance, the procedure seems simple, but careless actions can lead to cracks in the body, damage to the plumes or even damage to the fingerprint sensor, especially for modern models with adhesive mounts and glass panels.

In this article, we will analyze all the nuances: from the necessary tools to step-by-step actions for different Xiaomi series - Redmi, POCO, Mi and Black Shark, you'll learn how to avoid common mistakes, how to disassemble budget and flagship models, and what to do if the lid is stuck dead, and for those who are afraid of damaging the device, we've prepared alternative solutions without completely dismantling them.

What tools will be needed to remove the cover

Without the right set of tools, trying to open Xiaomi can end in failure, even if you have a shoulder hand, a plastic blade or a knife will not replace professional equipment.

  • ๐Ÿ”ง Plastic mediators or shoulder blades (thickness 0.1-0.3 mm) - for careful putting of the cover. Metal tools scratch the body!
  • ๐Ÿ”ฅ Dryer or thermo-air station (power 500-1000 watts) - for softening the glue. Optimal temperature: 60-80ยฐC.
  • ๐Ÿงฒ Suction cups (diameter 30-50 mm) - help to evenly lift the cover without damaging it.
  • ๐Ÿ“ Thin Torx screwdriver T3/T4 โ€” for the purpose of putting them under the stains).
  • ๐Ÿงด Isopropyl alcohol (90%+) โ€” Removing glue residues and cleaning contacts.
  • ๐Ÿ›ก๏ธ Protective gloves โ€“ glue and alcohol corrode the skin, and glass fragments can injure.

For models with a degree of protection IP53/IP68 (for example, Xiaomi 13 Ultra or Redmi Note 12 Pro+) You will need an ultra-thin mediator (0.05 And the magnifying glass -- the glue is thicker there, and the gaps between the lid and the frame are minimal. POCO F5 or black shark 5, where the lid is mounted on the latches, enough plastic blades without heating.

โš ๏ธ Warning: Never use knives, screwdrivers or other metal objects to lid the lid! Even a little pressure can lead to microcracks on the glass panel, which eventually turn into full-fledged faults. Models with curved glass (for example, Mi 11 Ultra) are particularly vulnerable).

Preparing the smartphone for dismantling: steps before removing the lid

Before you can get your tools right, you have to get the device ready, and neglecting these steps can lead to data loss, short circuits, or damage to the internal components, and here's a checklist of the required actions:

โ˜‘๏ธ Xiaomi Preparation for Disassembly

Done: 0 / 5

Pay special attention to the battery. If it is bloated (the lid is curved, the screen "steps away" from the body), do not heat the device - the risk of fire lithium-ion batteries at temperatures above 60ยฐC increases dramatically, and in such cases, you should contact the service center, and also check if there are stickers or film on the case, which can interfere with the uniform heating.

If you are working with a waterproof model (e.g. Xiaomi) 12S Ultra, note that once disassembled, the leakage will be broken. Recovery will require replacement of the adhesive seal and water resistance test. You can't do this at home, only on authorized services.

Before heating with a hair dryer, paste the screen with paint tape - this will protect it from accidental scratches when the mediator slips.

Step-by-step: how to remove the back cover on Xiaomi

The dismantling algorithm depends on the type of lid attachment, and we'll look at two main scenarios: glue mounting (most current models) and latches (budget Redmi series and the Redmi series). POCO). Letโ€™s start with the most difficult option โ€“ glue.

Method 1: Adhesive fastening (for Xiaomi) 11/12/13, Redmi Note 10/11/12, POCO F4/F5)

This is a method that works for smartphones with a glued back panel, and the main goal is to heat the glue evenly without overheating the internal components.

  1. Heat the hair dryer edge of the cover around the perimeter for 2-3 minutes, holding the nozzle at a distance of 3-5 cm Temperature - no higher than 80ยฐC (check with an infrared thermometer or touch the body - it should be hot but not scalding).
  2. While the lid is warm, attach the suction cup closer to the bottom edge (where the speakers are usually located) and pull up slightly. If the lid does not lend itself, heat the place for another 30 seconds.
  3. Insert a plastic mediator into the gap and carefully guide it along the edge, separating the glue. Don't try to tear the lid off right away, it will cause the plumes to rupture!
  4. Once the mediator has passed through the perimeter, slowly lift the lid, and if you feel resistance, check if there are any uncut glue.

Wireless charging models (such as the Xiaomi 13 Pro) may have an extra metal screen under the lid โ€“ it too needs to be carefully separated, as it is often glued to the battery.

Method 2: Latches (for Redmi) 9/10, POCO M3/M4, Older Mi A models)

Xiaomi's budget models are often assembled on plastic latches, making it easier to disassemble, but the other danger is fragile clips that are easy to break with careless pressing.

  1. Insert a plastic spatula in the gap between the lid and the middle frame (usually it is near the slot for the lid). SIM-map).
  2. Press carefully until you hear the first latch click. Don't force -- if the lid doesn't respond, check if the dust builds up.
  3. Swipe the blade along the edge, flipping the mounts one by one, start at the bottom and move counterclockwise.
  4. Once all the latches are opened, remove the cover by holding it by the top (there are often antenna plumes).

In models POCO X3 And the Redmi Note 9 Pro, under the lid, can have an additional metal frame attached to the screws. T3.

What to do if the lid does not lend itself?
If the mediator is heated and the lid is still not removed, it may be too old or too factory-made. In this case: 1. Reheat to increase the temperature to 85.ยฐC (but not higher!!). 2. Use a thinner mediator (0.05 mm) to penetrate the microgaps. 3. Apply a few drops of isopropyl alcohol around the perimeter - it dissolves the glue. 4. If nothing helps, contact the service - further attempts may damage the body.

Frequent Mistakes and How to Avoid Them

Even experienced craftsmen sometimes make mistakes when disassembling Xiaomi.-5 Failures that lead to breakdowns and ways to prevent them:

Mistake.Effects of consequencesHow to avoid
Heating above 90ยฐCMelting plastic clips, battery damage, detachment of the screen moduleUse thermometer, warm in short intervals (30-40 seconds)
A sharp lid-breakBreakage of the fingerprint scanner plume or antenna cablesCheck for plumes before complete removal, use suction cups
Use of metal toolsScratches on the body, short circuit when touching the boardWork only with plastic or wooden blades
Disassembly without battery shutdownShort circuit when touching the board, reset settingsTurn off the battery first (if you have access to the connector)
Ignoring glue residuePoor fixation of the lid after assembly, the hit of glue on the contactsRemove the glue with alcohol, apply a new layer during assembly

Pay special attention to models with a fingerprint sensor under the screen (for example, Xiaomi). 12T Pro) Its plume often runs under the battery, and if you unpack the lid, you can damage the contacts. If the scanner stops working after assembly, check the integrity of the plume and the density of the connector.

โš ๏ธ Note: In smartphones Xiaomi with infrared port (for example, Redmi Note 11 Pro)+) There's a fragile filter film under the lid, and if it's damaged, the IR port will stop working!

Features of disassembly for different Xiaomi series

The design of the back cover varies depending on the series and year of release. For example, the flagship Mi and Black Shark models often have a multi-layer mount (glue). + latch + We're going to use the same kind of hardware as the budget Redmis, and we're going to look at the key differences:

1. Xiaomi Mi Series (10/11/12/13)

The Mi flagships feature glass back panels with adhesive mounting and an additional metal screen underneath.

  • ๐Ÿ”‹ The battery is glued to the body - its removal requires heating and special traction tapes.
  • ๐Ÿ“ก The antenna plumes are soldered to the board - at a break will require soldering.
  • ๐Ÿ” The fingerprint sensor is integrated into the screen - disassembly without experience is fraught with its breakdown.

2. The Redmi Note series (8/9/10/11/12)

The most common lineup with plastic or glass covers, the Note 10 Pro and later uses glue, the old (Note 8) uses latches.

  • ๐Ÿ› ๏ธ In Redmi Note 11 Pro+ The cover is attached to 12 latches - they are easy to break when unevenly pressed.
  • ๐Ÿ’ง Models with IP53 have rubber seals - they need to be cleaned and replaced during assembly.
  • ๐Ÿ”Š The speakers are often glued to the lid - when it is removed, you can tear off the wires.

3. Series POCO (F/X/M)

Budget gaming smartphones POCO It is usually easier to understand, but there are nuances:

  • ๐ŸŽฎ V POCO F3/F4 glue-cover + 4 plug-in.
  • โšก V POCO X3 Pro battery soldered to the board - its replacement requires soldering.
  • ๐Ÿ”„ V POCO M4 Pro fingerprint scanner plume goes through the middle of the case - it is easy to hook the mediator.

4.Series of Black Shark (Gaming Smartphones)

Black Shark gaming devices have a reinforced mount due to the cooling system.

  • โ„๏ธ In Black Shark 5 Pro under the lid is a liquid metal radiator โ€“ it can not bend!
  • ๐Ÿ”Œ The battery is divided into two parts โ€“ you need to remove alternately.
  • ๐Ÿ•น๏ธ The buttons of shoulder triggers are glued - they are easy to tear off with careless disassembly.

๐Ÿ’ก

Before disassembling, be sure to check your Xiaomi model on the official support site - there are lid mount schemes for each series.

What to do after removing the lid: tips for assembly

Successful removal of the lid is only half the battle, and it is equally important to build the device properly to avoid leakage, sensors or wireless charging problems.

  1. Clean the contacts of glue residues with isopropyl alcohol, and pay special attention to the battery connectors, the camera and the fingerprint scanner.
  2. Check the plumes for integrity, and if you notice any tears, replace them before assembly.
  3. Apply a new glue (for example, B-7000 or T-7000) For waterproof models, use a sealant.
  4. Secure the lid starting at the top (where the plumes are usually located). Press it evenly, avoiding distortion.
  5. Check the functionality after assembly: camera, fingerprint scanner, wireless charging, speakers.

If Xiaomi does not turn on after assembly, check:

  • ๐Ÿ”Œ Battery connection (possibly the connector has left).
  • ๐Ÿ”‹ Battery charge (if it is completely discharged, you will need a charger with the function of "boost").
  • ๐Ÿ› ๏ธ Integrity of the board (with a short circuit, fuses can burn out).

For models with wireless charging (Xiaomi 13 Pro, Mi 11 Ultra) after assembly, check the alignment of the charging coil. If the smartphone is not charging from a wireless station, it may be that the coil has shifted or damaged.

Alternative methods: when you do not need to remove the cover

It is not always necessary to disassemble the body completely for repairs or upgrades, and in some cases partial access may be avoided or the body may be avoided altogether.

1. Replace the battery without removing the cover

In the Redmi Note models 8/9 and POCO M2 The battery can be replaced through a hole for SIM-cards, if previously:

  • ๐Ÿ”ง Unwrapped two screws under the plug.
  • ๐Ÿ”‹ Carefully pull the battery behind the tape (if any).
  • ๐Ÿ”Œ Disconnect the connector and connect a new battery.

This method is only suitable for models with a removable battery (there are few left).

2. Dust cleansing without disassembly

If the goal is to remove dust from speakers or connectors, use:

  • ๐ŸŒฌ๏ธ A compressed air cylinder (hold it vertically to avoid fluid leaking out).
  • ๐Ÿงน Soft brush (for example, for camera lenses).
  • ๐Ÿงฒ Magnetic holder for extracting metal debris from Type-C connector.

Repair without opening: official Xiaomi services

If you are not sure about your abilities, use support programs:

  • ๐Ÿ”ง Mi Care - warranty repair (valid for up to 2 years after purchase).
  • ๐Ÿ’ฐ Mi Protect โ€“ mechanical damage insurance (costs from 500) โ‚ฝ/year).
  • โšก Express replacement โ€“ in some services, the battery or screen is changed in 1 hour.

For owners of Xiaomi in Russia and CIS, the Mi Exchange program works - you rent an old smartphone and get a discount on a new one. This is more profitable than self-repair if the device is more than 3 years old.

If you only need to replace the protective glass or film on the back, contact the communication salons โ€“ many of them provide this service for 300-500. โ‚ฝ pieceless.

FAQ: Frequent questions about removing the Xiaomi lid

โ“ Can I remove the cover Xiaomi without a hair dryer?
Yes, but only for latched models (like Redmi). 9A or POCO M3). For adhesive covers (most modern Xiaomi), heating is mandatory - without it you risk tearing off the plumes or damaging the body. The alternative to a hairdryer is hot air from a kettle (direct steam to the edge of the lid for 5-7 minutes), but it is less effective.
โ“ How to know if the lid is on glue, not on latches?
There are a few signs: ๐Ÿ” There are no visible seams or gaps on the body (glue fastening). ๐Ÿ“ฑ Glass or metal cover (usually glued). ๐Ÿ’ง The device has a certificate of protection against water (IP53/IP68) โ€” These models are always glue-on. ๐Ÿ”Š When you press the lid, you hear a deaf sound (the latches make a slight click), and you can find accurate information in the disassemblies on YouTube (model search) or on the iFixit website.
โ“ What to do if the fingerprint scanner stopped working after removing the cover?
It's one of the most common problems. Causes and solutions: ๐Ÿ”Œ The plume has gone, make sure it's tightly connected to the motherboard. ๐Ÿ”ง The plume is damaged - if tears are noticeable, replacement will be required (cost 500-1500) โ‚ฝ). ๐Ÿ“ฑ Settings are lost - restart the phone and re-add the fingerprint to Settings โ†’ Passwords and security. ๐Ÿ› ๏ธ The sensor itself is damaged โ€“ if the scanner is built into the screen (as in Xiaomi) 12T), If the scanner doesn't work after checking the plume, try resetting to factory settings (Settings) โ†’ The phone. โ†’ Resetting settings).
โ“ What glue to use to glue the cover back?
The choice of glue depends on the model: ๐Ÿ“ฑ For most, Xiaomi is a good fit. B-7000 (transparent, elastic) or T-7000 (stronger). ๐Ÿ’ง For waterproof models (IP68) need a sealant LOCTITE 595 or similar. ๐Ÿ”‹ For the battery, use a double-sided scotch 3M 9448A (How to apply: Clean the surface with alcohol. Apply a thin layer of glue around the perimeter of the lid, stepping 1-2 mm from the edges. Press the lid and fix it with tape for 10-15 minutes. Do not turn the phone on for 1 hour - the glue must be fully polymerized.
โ“ Can you replace the back cover with Xiaomi if it cracked?
Yeah, but there's nuance: ๐Ÿ›’ Where to buy: original lids are sold on AliExpress (price 500โ€“2000) โ‚ฝ), But they often go without glue and seals. POCO You can find non-original covers cheaper (200-800) โ‚ฝ). ๐Ÿ”ง Replace: Remove the old lid (as described above). Move all components (camera, scanner, antenna plumes) to the new lid. Apply glue and press the lid. โš ๏ธ Risks: The new cover may not match in color (especially Xiaomi with gradient coloration). Wireless charging may work worse due to the displacement of the coil. Water protection will be broken (if it was). For models with built-in fingerprint scanner (for example, Xiaomi 13), replacing the cover requires transferring the sensor is a complex procedure, it is better to entrust its service to the user.
