- π οΈ Train repairs β for example, camera malfunction, speaker, or power buttons often require access to internal components.
- π§Ή Dust cleaning β over time, dust and pile accumulate under the lid, which can lead to overheating or failures in the operation of sensors.
- π§ Installing additional modules β some users upgrade their devices by adding, for example, wireless charging or NFC-chip (unless it has been pre-installed).
- π§ Eliminating the effects of fluid intrusion β even if the phone doesnβt turn on after water, timely disassembly and drying can save it.
Important: if your Xiaomi is still under warranty, self-disassembly will cancel the manufacturer's warranty obligations, in this case, it is better to contact the service center.+ etc.) after disassembly may lose leakage - they will have to be re-glued.
What tools will you need

- π§΄ Isopropyl alcohol (90%+) β for cleaning glue residues and degreasing the surface before reassembling.
If you do not plan to repair regularly, you can buy a ready-made set for disassembling smartphones (costs from 300 to 1000 rubles on AliExpress or in electronics stores). For one-time use, even a guitar mediator and hair dryer are suitable (but be careful - a home hair dryer is weaker than a professional one, and the glue may not soften enough).

Before disassembling, take a photo of the back cover of the phone β this will help to correctly position it when assembled back, especially if it has asymmetric elements (for example, a cutout for the camera).
Step-by-step: how to remove the back cover
The process of removing the lid depends on the Xiaomi model, but the general scheme looks like this:
1. Warming of glue (for models with gluing)
Most modern Xiaomi smartphones (starting with the Redmi Note 10 and later) have a glued lid. To remove it, you need to soften the glue:
- Turn on the dryer at medium power (temperature) 60-80Β°C).
- Heat the lid around the perimeter during 2-3 minutes, evenly waving a hairdryer along the edges.
- Donβt stay in one place for too long β you can damage the plastic or display.
2. Cover smacking
Use a plastic spatula or suction cup:

- In the resulting gap insert a plastic spatula and carefully lead it along the edge, separating the lid.
- On models with an aluminum frame (for example, Xiaomi) 12S) Be careful, the metal may bend.
3. disconnection of the plumes (if the cover is not completely removed)
Some phones (for example, POCO X3 Or Redmi 9, the lid is not only attached to the glue, but also to the latches:
- Are there any hidden screws under the stickers (for example, near the slot) SIM).
- Whether the battery plume or antenna interferes, it must be carefully disconnected.
β οΈ Warning: If the lid is not amenable, do not use excessive force! inside can be fragile elements (for example, the glass panel of the camera at Xiaomi). 13T). Better to warm up the glue again or check if all screws are unscrewed.
What to do if the lid is cracked?
Models with screws (old Xiaomi)
On phones before 2018 years (e.g. Redmi) 4X, Mi A1) The lid is often attached to the screws, and they need to be unscrewed with a cross screwdriver (usually). 6-8 And then the lid is removed without heating, but be careful, there may be some brittle latches underneath.

|---|---|---|---|
| Redmi Note 12 Pro+ | Glue + latches | Yes. | Glass cover, fragile. |
| Xiaomi 13 Ultra | Glue + sealant | Yes. | Repeated sealing is required |
| POCO X3 Pro | Glue + 2 screws | Yes. | Screws under the sticker y SIM-tray |
| Redmi 9A | Latches | No. | Plastic cover, removed with a spatula |
| Mi 11 Lite | Clay. | Yes. | Thin cover, easy to bend |
Frequent Mistakes and How to Avoid Them
Even experienced craftsmen sometimes make mistakes when disassembling Xiaomi, and here are the most common ones and ways to prevent them:

- πͺ Using metal tools -- knives, screwdrivers, or scissors scratch the body and can pierce the plumes. Use only plastic blades.
- β‘ Disassembly when the phone is on is a risk of short circuit. Always turn off the device and remove the battery (if possible).
- π§² Loss of screws or latches β some models (e.g. Xiaomi Mi 10) have tiny screws that are easy to lose.
- π¦ Getting moisture after disassembly β if your phone had protection IP68, After removing the cover, it must be restored with a new adhesive side.
β οΈ Warning: If after removing the lid you notice that the battery plume is severed or there are traces of oxidation on the board, do not turn on the phone! This can lead to fire.
Another common problem is the squeak or squeak of the lid after assembly, which means it doesn't fit tightly.
