The Xiaomi A5 is a popular smartphone with a non-removable back, but sometimes users need to open it to replace the battery, repair plumes or clean up dust. Unlike models with folding covers (for example, the Redmi 4A), here you have to work hard – the panel is held on glue and plastic latches, and the awkward location of the clip can lead to cracks when disassembled sloppy.
This article will help you understand how to remove the cover of the Xiaomi A5 without damage, what tools you will need and what to look for. We will look at two methods - using a suction cup and a mediator (for beginners) and a special tool for disassembling (for experienced users), and you will learn how to avoid typical mistakes: tearing off the plume of the fingerprint scanner or damaging antenna contacts.
⚠️ Important: Disassembling your smartphone will void the warranty (if it is still valid). If you are not sure about your skills, contact the service center. A5 (model M2006C3LG), They may be different for other versions of the A series.
Preparation for disassembly: tools and security measures
Before you open the lid, prepare the workspace and tools.
- 🔧 Plastic mediator or guitar mediator (thickness 0.3-0.5 mm) – to separate the cover from the body.
- 🧲 Suction (better with a metal ring) - to tuck the panel without scratches.
- 🔥 Hair dryer (not necessarily, but will help soften the glue) - heat the case to 50-60°C, so that the latches are easier to succumb to.
- ⚡ Screwdriver. T3 or T4 — to unscrew the screws under the lid (if you plan to completely disassemble).
- 📦 Container for screws - so as not to lose small details.
Also prepare an antistatic mat or at least work on a table without carpeting - static electricity can damage the motherboard. If you don't have experience, practice on an old smartphone or watch a video disassembly of the Xiaomi A5 on YouTube to understand the location of the latches.
⚠️ Warning: Do not use metal tools (knives, screwdrivers) to lid the lid - they leave scratches and can damage plastic clips. If there is no mediator, take a plastic card or bank card (but it is less flexible).
Method 1: Opening the lid with a suction cup and a mediator (for beginners)
This is a way for first-time smartphone users to take apart a smartphone, which is less risky, but requires care.
- Turn off Xiaomi. A5 and extract SIM-card from the tray (if installed).
- Stick the suction cup onto the bottom of the back panel (closer to the USB-C connector). Press it to stick tightly.
- Pull the sucker up with moderate force - a small gap (1-2 mm) should appear.
- Put a plastic mediator in the gap and gently run it along the edge of the case, separating the latches. Start at the bottom and move counterclockwise.
- When all the clips are snapped, remove the lid. Don't pull it out too hard, because plumes (like a fingerprint scanner) can be glued under the panel.
If the lid is not amenable, heat the body slightly with a hairdryer (don't direct hot air to the screen!) The glue will become softer and the latches will open easier. The temperature should not exceed 60 ° C - otherwise you can damage the battery or display.

Critical detail: on the Xiaomi A5, the fingerprint scanner plume is glued to the back. If you sharply pull the lid, it can come off - the smartphone will lose the fingerprint unlock function! To avoid this, after the clips are separated, raise the panel 1-2 cm and check if there are any plumes under it.
Method 2: Disassembly with a special tool (for experienced)
If you have a smartphone disassembly kit (like the iFixit Pro Tech Toolkit), the process will go faster.
- 🔨 Plastic lever (spader) - for neat underwear.
- 🧲 Suction cup with a ring - more reliable than usual.
- 🔥 Thermo-air station (replacement of the hair dryer) - for uniform heating.
Algorithm of action:
- Heat the body around the perimeter (especially in the corners where the latches are located).
- Secure the suction cup and pull upwards to form a gap.
- Put the spader in the gap and gently "walk" around the perimeter, snapping clips. On the Xiaomi A5, there are about 12-14 pieces.
- When all the latches are open, lift the lid and check the plumes. If they're glued, carefully unplug them with a spader.
The advantage of this method is that there is less risk of damage to the lid, because the tools are thinner and more flexible. However, without experience, it is easy to overheat the case or tear the plume. If you are disassembling a smartphone for the first time, you should use the first method.

Common Mistakes and How to Avoid Them
Even with careful disassembly, users often make mistakes that lead to breakdowns.
| Mistake. | Effects of consequences | How to avoid |
|---|---|---|
| The lid's jittery. | Breakage of the fingerprint scanner plume or antenna contacts | Separate the panel slowly, checking for plumes |
| Use of metal tools | Scratches on the body, damage to clips | Use only plastic mediators. |
| Hydrogen overheating | Deformation of plastic, battery damage | Heat no longer than 1-2 minutes, temperature to 60 ° C |
| Lack of antistatic protection | Failure of the motherboard or chips | Work on an antistatic mat or hold on to a grounded object |
Another common problem is damage to the adhesive layer. If you plan to reassemble your smartphone, buy 3M double-sided tape (0.2-0.3 mm thick) or special glue for smartphones (e.g. B-7000) beforehand. The old glue loses its stickiness after disassembly, and the lid will dangle.
⚠️ Warning: If the smartphone doesn't turn on after disassembly, check: Is the battery connected (sometimes the plume leaves when the lid is removed); Is the motherboard damaged (look for blackened elements); Is the contacts closed (for example, due to the hit of metal shavings).
What to do after opening the lid?
When the lid is removed, the internal structure of the Xiaomi A5 will open before you:
- 🔋 Battery - glued to the body, disconnected after removing the protective film.
- 📡 Antenna contacts – thin metal strips around the perimeter.
- 🔍 Fingerprint scanner - the plume goes to the motherboard.
- 🔊 The speaker and microphone are located at the bottom.
If the purpose of disassembly is to replace the battery, follow the following steps:
- Unplug the protective film from the battery (usually black).
- Disconnect the power plume with a plastic spader.
- Put the battery in a mediator and pull it out gently. Don't rot it or use metal tools -- lithium-ion batteries can ignite if punctured!
For other tasks (dust cleaning, camera plume replacement), learn the layout of the components. On the Xiaomi A5, the motherboard is under a metal screen — to get to it, you need to unscrew several T3 screws.
💡
Before assembling your smartphone, wipe the internal contacts with alcohol (90% or higher) to remove dust and improve connection. Do not use wet wipes or acetone!
How to reassemble the smartphone back?
Assembling the Xiaomi A5 after disassembly requires as much accuracy as opening.
- Check all the plumes – they should be connected tightly, without inflections.
- If you have removed the battery, make sure that the new (or old) is firmly glued. Use double-sided tape or special glue.
- Put the antenna contacts in place - they should lie flat, without clamps.
- Secure the back cover starting at the top (where the fingerprint scanner latches are located). Press all corners to make the clips snap.
- Check your health: Turn on your smartphone and test the sensor, camera, speakers and fingerprint scanner.
If the lid is hanging or not fitting tightly after assembly, then the adhesive layer is worn out.
- Buy a new double-sided scotch (e.g. 3M 9448A).
- Carefully peel off old glue residues from the lid and body (you can use isopropyl alcohol).
- Stick new strips of tape around the perimeter and reassemble the smartphone.
💡
If the fingerprint scanner doesn't work after assembly, it's probably broken off or its plume is not connected correctly, take the phone apart again and check the connection.
When is the best time to contact the service?
It is not always advisable to disassemble the Xiaomi A5 yourself.
- 🔧 Replace the display module (special equipment is required to peel off the glass).
- 🔌 Problems with the motherboard (several functions stopped working at the same time).
- 💧 Smartphone hit the water (needs cleaning with ultrasound and replacing damaged components).
- 🔋 Battery swelled (risk of fire when self-extracting).
The cost of dismantling in the service is usually 500-1500 rubles (depending on the task), for example, replacing the battery will cost 2000-2500 rubles (taking into account the work and the original battery), and repairing the plume of the fingerprint scanner - 1000-1500 rubles.
If you still decide to disassemble the smartphone yourself, but faced difficulties (for example, you can not disconnect the plume or the lid does not open), do not make excessive efforts.
