The back cover of Xiaomi Redmi 6A β€” This is not just a security element, but a barrier that hides access to the battery, a slot for the battery. SIM-Many users are faced with the need to remove it, whether it is replacing the battery, cleaning from dust or repairing after a fall. However, the design of the smartphone involves the use of glue and fragile plastic latches, which are easy to break if you carelessly handle.

In this article, you'll find a step-by-step photo guide, a list of tools you need, and a list of common errors that cause damage to the battery case or plume, and we'll also look at where you can do without special equipment, and when to go to a service center, and if you've never taken your smartphone apart before, this guide will help you avoid costly mistakes.

Preparation for the disassembly: what you will need

Before you start removing the lid, make sure you have everything you need. Xiaomi Redmi 6A is not a lightweight model (unlike old push-button phones), so you can’t do without tools. Here is the minimum set:

  • πŸ”§ Plastic blade (or mediator) - for gently putting the lid on. Metal tools can leave scratches!
  • πŸ”₯ Hair dryer or thermo-air station - to soften the glue around the perimeter (temperature 60-80)Β°C).
  • πŸ“ Suction cups (1-2 pcs) - help to evenly lift the cover after heating.
  • πŸ”‹ Tweezers – to disconnect the battery plume (if necessary).
  • 🧴 Isopropyl alcohol (90%+) β€” Removal of glue residues (optional but useful).

If you don't have a thermal air station, you can use a hair dryer -- you can keep your body above 80Β°C, so you don't damage the screen or the battery, and you can use a needle or a paper clip for the initial tweaking, but you have to be very careful.

⚠️ Warning: Do not use a knife or screwdriver to lid the lid! even a slight pressure of metal can lead to cracks in the plastic or damage to internal components.

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

The process of removing the Redmi 6A cover consists of several steps, follow them strictly in order to minimize the risks:

  1. Turn off the phone and remove the tray for SIM-This will prevent short circuits and make it easier to access the latches.
  2. Heat the edges of the body with a hair dryer for 1-2 minutes, keeping it at a distance of 5-7 cm.
  3. Hold the suction cup to the bottom of the phone (where the charging connector is) and pull it up. If the lid doesn't lend itself, repeat the heat.
  4. Put the blade in the gap and gently swipe it around the perimeter, separate the latches. Start at the bottom edge!
  5. Remove the lid by holding it over the top (there's a battery plume running through).

If the lid doesn't respond the first time, don't put too much effort into it. You'd better do it again. In Redmi 6A, the latches are unevenly arranged, with more latches in the lower and upper parts of the body.

Critically, after removing the lid, do not touch the battery plume with your bare hands - static electricity can damage the motherboard. If you need to disconnect the battery, use tweezers or a plastic tool.

Common Mistakes and How to Avoid Them

Even experienced users sometimes make mistakes when disassembling the Xiaomi Redmi 6A. Here are the most common of them and ways to prevent them:

Mistake.Effects of consequencesHow to avoid
Use of metal toolsScratches on the body, damage to plumesUse only plastic blades
Overheating of the shell (>80Β°C)Deformation of plastic, detachment of the screen moduleControl the temperature with a hair dryer at a distance of 5-7 cm
Removal of the lid without disconnecting the latchesBreakage of battery or camera plumeCarefully conduct the shoulder blade around the perimeter
Touching the motherboard without groundingStatic electricity could knock out chipsWorking in an antistatic bracelet or touching metal surfaces

Another common problem is damage to the sealing gum (if any) that is not present in the Redmi 6A, but if you are disassembling a moisture-protected model (such as the Redmi 6 Pro), beware: damage to the seal will result in loss of water resistance.

⚠️ Warning: If the phone stopped turning on after the lid was removed, the battery plume or battery probably left!

What to do if the lid is not removed?

Sometimes, even after heating, the Redmi 6A remains tightly glued to the top, and here are a few ways to fix the problem:

  • πŸ”„ Repeat heating 1-2 times, paying attention to the corners of the body - there is usually more glue.
  • πŸ’§ Use isopropyl alcohol: apply a few drops around the perimeter of the lid (it dissolves the glue).
  • πŸ”§ Try another shoulder blade – sometimes a thin guitar mediator works better than a standard shoulder blade.
  • πŸ“ž Contact the service if you are afraid of damaging your phone. in some cases, the glue may be too strong (for example, after repairs).

If you notice that the lid has started to creak or bend when pressed, this is a sign that the glue has already softened, but the latches are still holding, in which case you need to carefully work the shoulder blade all sides, starting with the bottom edge (where the charging connector).

What to do if the latch breaks?
If you remove the lid, you break the plastic latch, don't panic. You can fix it back with a little glue (e.g., B-7000) or double-sided tape, but you can also note that after that, the leakage of the case will break, and the phone will become more vulnerable to dust and moisture.

How to collect the phone back: tips

Building Xiaomi Redmi 6A after removing the lid requires no less care than disassembly.

  1. Check the battery plume – it should be tightly connected to the motherboard.
  2. Remove the residues of glue from the cover and body (you can use alcohol and cotton swab).
  3. Line the lid before you press it. The latches should fall into place effortlessly.
  4. Heat the lid before fixing (if you use glue) - this will improve adhesion.

If you haven't used glue in the assembly, the lid may hold less tightly, so you can temporarily lock it with paint tape around the perimeter, but it's not a long-term solution, and for reliability, you'd better put a thin layer of B-7000 glue or its equivalent.

When it is better not to take risks: cases for the service center

While the Redmi 6A is a simple disassembly, there are some situations where you can trust the professionals:

  • πŸ”§ If the phone gets into water - corrosion on the board may require special cleaning.
  • ⚑ If after the fall the screen or touch screen does not work, the plume may be damaged.
  • πŸ”‹ If the battery is swelling - its replacement at home is dangerous!
  • πŸ“± If the phone does not turn on after a failed firmware - soldering work may be required.

The cost of dismantling in the service usually does not exceed 500-1000 rubles, while repairs after an unsuccessful independent attempt can cost many times more. For example, replacing the battery plume or display module in the Redmi 6A costs from 1500 to 3000 rubles.

What if the phone does not turn on after removing the cover?
The battery plume or battery probably has gone, turn off the battery (if it's removable), then plug it back in and try to turn on the phone. If it doesn't work, check if there's any damage on the motherboard (blackened elements, burn marks).
Which glue is better to use to fix the cover?
Optimal options: B-7000 is a universal adhesive for electronics, does not conduct current. LOCTITE 406 is a fast-acting cyanoacrylate adhesive. Bilateral 3M VHB tape β€” if you do not want to use liquid glue. Apply the adhesive in a thin layer, avoiding contact with connectors or speakers.
Can I replace the battery in the Redmi 6A?
Yes, but it requires care. Once the lid is removed, you need to: Disconnect the battery plume, put a plastic blade on the battery (it's glued), install a new battery and lock it with glue. Importantly, use a battery with the same capacity (3,000 mAh) and voltage (3.85V). Cheap analogues can quickly fail.
What to do if the switch button breaks during disassembly?
Power button at Redmi 6A If it breaks, check if the plume has moved away from the board (you can press it carefully with tweezers). If the button is physically damaged, you will need a replacement (the detail is worth it). ~300-500 rubles. Temporary solution: use of the program ADB switching on the phone via PC.
