Disassembly Xiaomi Redmi 6: how to remove the back cover without damage

Why to remove the cover and when it is dangerous

Removing the back cover of the Xiaomi Redmi 6 is a procedure that owners face when replacing a battery, repairing plumes or cleaning from dust. However, the design of the budget smartphone of 2018 has features: the lid is glued around the perimeter and fixed with plastic latches that are easy to break when sloppy dismantling. Unlike Xiaomi’s flagship models, there are no magnetic mounts or removable panels, only glue and brittle plastic.

The main reasons for disassembly are: replacing a bloated battery (a typical problem after 2-3 years of use), repairing a charging connector or speaker, and recovering from a fall. But before you start taking up tools, assess the risks: damage to the fingerprint plume (located under the lid), breaking off the flexible contacts of the screen or loss of leakage. If your Redmi 6 is still on warranty, you better contact the service center, since self-repair will cancel it.

In this article, you will find a step-by-step photo instruction, a list of tools you need, and tips for avoiding common mistakes, and we will also discuss alternative methods (such as heating with a hairdryer) and explain when to stop disassembling yourself.

Preparation: Tools and Conditions for Safe Disassembly

To remove the Redmi 6 cover, you'll need a specialized toolkit, and using the tools at hand (knife, credit card, or screwdriver) is almost guaranteed to cause scratches on the body or latch breaks.

• 🔧 Plastic mediator (0.5–0.7 mm thick) – for separation of cover and body.
• 🔥 Dryer or thermo-air station (power from 1000 W) - for softening the glue.
• 🧲 Suction cup (3-5 cm diameter) - helps to lift the cover after heating.
• 🛠️ Thin Torx screwdriver T3 — screw-off.
• 📦 Container for screws - so as not to lose small details.

Also, prepare the workspace: the desk should be clean and lit, and all tools are at hand. SIM-If the battery is swollen, don't heat the case with a hairdryer, it can cause fire.

⚠️ Note: If your Redmi 6 has been in water or has been in contact with liquid, disassembly may result in a short circuit, in which case you need to dry the device in rice or silica gel for at least 48 hours before removing the lid.

Step-by-step: how to remove the cover without damage

Follow this algorithm to minimize the risk of breakdown, and it takes 15 to 30 minutes depending on your experience.

Step 1: Heating the glue around the perimeter

Turn the dryer on at medium power (temperature ~60-70°C) and evenly warm the back cover for 2-3 minutes. Keep the hair dryer at a distance of 10-15 cm so as not to overheat the plastic. Pay special attention to the corners and areas near the chamber - there is the glue most. Sign of readiness: the cover will become slightly malleable when pressed.

Step 2: Separation of the cover by a mediator

With a suction cup, grab the top of the lid (near the speaker) and pull up slightly. Insert a mediator into the resulting slit and carefully guide it along the end, separating the glue. Don't try to tear the lid off immediately, this will break the latches! Move gradually, 1-2 cm at a time.

Is the cover separated along the entire perimeter?|Is there any resistance when the mediator moves?|Are there any unheated areas of glue left?|Are you ready for a possible snag of the print plume?-->

Step 3: Turn off the plumes

When you take off the lid, you'll see the battery and some plumes. Don't pull the lid abruptly, it's connected to the body with a flexible fingerprint scanner cable. Carefully disconnect the plume connector (it's on the right of the battery, next to the power button) with a plastic shoulder blade.

Now the lid is completely free. Place it on the clean surface with the inner side upwards so that the coating is not damaged.

💡

If the glue is too strong and does not respond to the mediator, repeat the dryer heating for another 1-2 minutes. Do not increase the temperature - this can warp the plastic or damage the battery.
