Why Removing Xiaomi’s Cover Needs a Special Approach
Xiaomi smartphones are known for their value for money, but their maintainability is often questionable. Most models have a back cover glued to the body, which makes it difficult to disassemble, but protects the device from dust and moisture. If you need to replace the battery, speaker or camera, the first thing you have to do is remove the cover.
The main problem is the risk of damage to the plumes or the body itself if you do not open it properly. For example, the Redmi Note 12 Pro has a thin plume of a fingerprint scanner under the lid, and the POCO X5 Pro has fragile antenna contacts, and we will tell you how to avoid typical errors and maintain the warranty (if it is still valid).
Important: If you're not sure about your skills, you should go to a service center, but if you decide to do it yourself, follow the instructions below.
What tools will be needed to disassemble
Without the right tools, it's almost impossible to remove the Xiaomi lid. Here's the minimum set:
- 🔧 Plastic blade (or mediator) - for careful liding
- 🔥 Hair dryer (or thermo-air station) - to soften glue
- 🧲 Suction cups – help lift the cover after heating
- ⚙️ Screwdriver. T3/T4 — to the stainless stains, if any)
- 📏 Plastic tweezers - for working with plumes
Don’t use metal objects (knives, screwdrivers) – they will scratch the body and can damage the internal components. If you have an IP-certified model (for example, Xiaomi 13 Ultra), be especially careful: after disassembling the water protection will break.
Preparing the smartphone for dismantling: steps before removing the lid
Before you start, do these steps:
☑️ Preparation for disassembly
Pay special attention to the battery. If it swells, do not heat the body with a hairdryer, this can lead to fire, in which case you should contact the service immediately.
Also check if there are any stickers left on the case, and if they are damaged, the warranty will be void. If the warranty is still in place, weigh the risks: self-repair may be more expensive.
⚠️ Note: Do not disassemble your smartphone at a lower temperature +15°C – the glue becomes too brittle and the cover may crack.
Step-by-step: how to remove the back cover
The process of disassembly depends on the model, but the overall scheme is the same.+:
- Heat the case. Turn the dryer on to the minimum power (or set a temperature of 60-70 ° C) and evenly warm the back cover for 2-3 minutes. Do not stay in one place - this can melt the plastic.
- Scapula squashing. Start at the bottom edge (near the charging connector) — the glue is usually weaker here. Insert a plastic blade and gently run along the body.
- If the lid doesn't lend itself, attach the suction cup closer to the top edge and pull it up. Don't use excessive force!
- The plumes are disconnected. Once the lid is removed, you'll see a battery and some plumes that you need to unplug before you continue to disassemble.
The POCO F4/F5 has additional latches attached to the lid, which need to be gently snapped with a blade. The Xiaomi 12T has a metal frame under the lid, which will also have to be removed.
💡
If the glue is too strong, repeat the heat again. Don't try to tear the lid off by force, it will lead to cracks.
Frequent Mistakes and How to Avoid Them
Even experienced users sometimes make mistakes, and here are the most common ones:
| Mistake. | Effects of consequences | How to avoid |
|---|---|---|
| Too much heat by a hair dryer | Melting plastic, battery damage | Keep the hair dryer at a distance of 10-15 cm, use the minimum temperature. |
| Use of metal tools | Scratches on the body, damage to plumes | Only plastic spatulas and suction cups |
| A sharp lid-break | Trail break, cracks in the glass | Gradually lift the cover, starting from the corners |
| Ignoring plumes | Damage to the fingerprint sensor or camera | Disconnect the plumes before further disassembly |
If you hear a crunch or crackle during the disassembly, stop the process immediately, which may mean that you have damaged the internal components.
⚠️ Note: Xiaomi 13 Lite and Redmi Note 12 Discovery models have fragile antenna modules under the cover, and damage to them will lead to loss of network.
Features of disassembly for different models Xiaomi
Not all Xiaomi smartphones are understood the same way.
- 📱 Redmi Note 10/11/12: The lid is glued around the perimeter, but it holds weaker than the flagships.
- 📱 POCO F3/F4/F5: Additional latches on the sides, neatness on the undercoat.
- 📱 Xiaomi 12/13/14: The metal frame makes it difficult to disassemble, and we need special tools to remove the middle layer.
- 📱 Black Shark 5/6: Gaming smartphones have a reinforced lid mount. a professional hair dryer is recommended.
Older models (like the Redmi 4X or Mi A1) can remove the lid without heating, it is held on plastic latches, but newer devices (2022 and later) use glue.

How to assemble a smartphone back: tips for reverse assembly
Assembling is often more difficult to disassemble.
- Check the plumes. Make sure all the connectors are tightly connected, but not skewed.
- Use new glue. Old glue loses its properties after heating. Buy 3M double-sided tape or special glue for smartphones.
- Heat the lid before sticking it, which will help the glue to grip better.
- Check the buttons. After assembly, make sure the volume and power buttons are running smoothly.
If after the assembly of the smartphone does not turn on, check:
- Connecting the battery (sometimes the plume goes away)
- Integrity of charging contacts
- Correct installation SIM-map
If there's a problem, you may have damaged the motherboard, and in that case, you can't do without a service center.
💡
The most common cause of malfunction after assembly is a poorly glued cover, which is why the contacts of antennas or buttons do not come into contact with the board.
