Removing the back cover of the Xiaomi Redmi 5 Plus is a challenge that owners face when replacing a battery, repairing a camera or cleaning connectors. Despite its apparent simplicity, the process requires caution: the plastic panel is attached to the latches and adhesive layer, and improper actions can lead to cracks or damage to the plumes. This article will examine all the steps from tool preparation to final dismantling, taking into account the specifics of the Redmi 5 Plus model (codenamed Vince).
Many users mistakenly believe that the mediator and force are enough to parse, but in practice, the Redmi 5 Plus has fragile clips around the perimeter and a thin fingerprint cable that is easy to damage. We will tell you how to avoid typical errors, what tools are really needed, and what to do if the lid is “rigged” with time, the instructions will be suitable for both the original version and modifications with NFC (for example, the Redmi Note 5 in some regions).
Before you start, make sure your Xiaomi Redmi 5 Plus is off and the battery is at least 25% drained, which minimizes the risk of short circuits in accidental contact with the board. If you remove the battery cover, prepare a new one in advance: the original batteries for this model have a capacity of 4000 mAh and are marked BM43 or BM44.
Tool preparation: what will be needed to analyze
Removing the back cover of the Redmi 5 Plus neatly requires a specialized toolkit, and using improvised tools (knives, credit cards) often results in scratches or chipped plastic.
- 🔧 A plastic mediator or suction cup is the main tool for deleting the lid. The mediator should be flexible, but not too soft (optimal thickness is 0.5-0.7 mm).
- 🔨 A thin screwdriver with a flat tip (for example, iFixit Jimmy or similar) - will help to lid the lid at the starting point.
- 🧲 Magnetic substrate or tray for screws - so as not to lose small details (if you have to unscrew the screws under the lid).
- 🔥 Hair dryer or thermoair station - to soften the adhesive layer (optional, but simplifies the process).
- 🧴 Isopropyl alcohol (90%+) — cleaning up the glue after removal.
If you are planning further repairs (e.g. battery replacement), prepare:
- 🔋 New battery with glue strips (if they are not included in the kit).
- 📏 Plastic spatula for neat detachment of plumes.
- 🔌 Multimeter – to check the voltage on the new battery before installation.
⚠️ Warning: Do not use metal tools to lid! even a small scratch on antenna tracks (located under plastic) can degrade Wi-Fi or cellular signal.
Step-by-step: how to remove the back cover
The dismantling process is broken down into steps with photos of key moments. Follow the instructions sequentially, without missing steps. If the lid fails, don't put too much effort into it, go back to the previous one.
Step 1: Heating the body (optional)
If the phone was in use for a long time and the cover "feels," warm up the back panel with a hair dryer for 1-2 minutes, holding it at a distance of 10-15 cm The temperature should be comfortable for the hand (maximum 60 ° C. This will soften the glue and facilitate separation. Do not overheat the area near the camera - the thermal paste under it can melt and stain the lens.
Step 2: Separation of the cover by a mediator
- Start at the bottom edge (on the USB-C side of the connector). Insert the mediator into a gap between the lid and the body by 2-3 mm.
- Carefully steer the instrument along the side faces, releasing the latches one by one, and you'll hear the characteristic clicks.
- Do not try to tear off the lid immediately - move slowly, 1-2 cm at a time.
Step 3: Release the upper part
The hardest part is the top edge, where the fingerprint scanner plume runs, where the latches hold tighter. Use the second mediator to lift the lid evenly without pulling the plume. If you feel resistance, go back to the hairdryer.

Common Mistakes and How to Avoid Them
Even experienced users sometimes make mistakes when parsing the Redmi 5 Plus, and here are the most common ones and ways to prevent them:
| Mistake. | Effects of consequences | How to avoid |
|---|---|---|
| Use a knife instead of a mediator | Scratches on the body, damage to antenna tracks | Use only plastic or nylon tools |
| A sharp lid-break | Breaking the fingerprint or camera plume | Separate the cover gradually, checking the tension of the plumes |
| Dryer overheating | Deformation of plastic, melting of thermopaste | Keep the hair dryer at a distance of 10+ cm, do not heat one point longer than 10 seconds |
| Attempting to remove the cover without heating | Broken latches, cracks on the lid. | For old phones, heating is mandatory - the glue hardens over time |
💡
If you remove the battery replacement cover, take a picture of the plumes and screws before they are disconnected, which will help avoid errors when reassembling, especially if you are doing repairs for the first time.
⚠️ Warning: On some Redmi 5 Plus batches (especially those released in 2018), the fingerprint scanner plume is glued to the lid. If you feel it resists, don't pull the lid any further! Carefully tuck the plume in with a plastic spatula or unplug it from the motherboard.
What to do after removing the cover: further actions
When the lid is successfully removed, the internal structure of the Redmi 5 Plus will open before you.
- 🔋 Battery - takes up most of the space. If the purpose of the parsing is to replace it, first disconnect the battery connector from the motherboard (it is under a black insulation tape).
- 📷 The camera and the fingerprint scanner are fragile plumes of these modules. Don't touch them unnecessarily.
- 📶 The antenna tracks are metallized strips around the perimeter, and if they're damaged, they'll make the signal worse.
- 🔧 Rotors – The Redmi 5 Plus uses Phillips #00 screws!
If you have removed the cover for cleaning connectors (for example, USB-C or audio connector), use a wooden toothpick and isopropyl alcohol. Do not use metal objects! To remove dust from the speakers, a can of compressed air will do (hold it vertically to avoid liquid).
How to install the cover back: Assembly tips
Reverse lids are as important as removing them.
- Make sure all plumes are connected and not twisted.The fingerprint scanner plume should lie flat, without clamps.
- Make sure the antenna tracks are not contaminated or damaged, and clean them with alcohol if necessary.
- Line the lid up the grooves before pressing it. Start at the top (camera side), then click the side clips.
- For a reliable fix, warm the lid with a hair dryer (as in removing) and press it evenly throughout the area, which will help the glue to better grasp.
💡
If the phone doesn't turn on after assembly, check the battery and power plume connection. A common error is that the battery connector is not fully connected, causing the device to not respond to the power button.
If the cover after installation of "luftite" or not tightly fits, the reasons may be as follows:
- Not all the latches are fixed (check the lower and upper edges).
- The adhesive layer is worn out (the solution is to apply a thin layer of bilateral tape around the perimeter).
- The clips are deformed (in this case, it may be necessary to replace the cover).
Alternative methods: when the standard method does not work
Sometimes the Redmi 5 Plus lid refuses to be removed even after heating and tidy tweaking.
- Strong adhesive layer (typical for phones that have been repaired).
- Deformation of the body after falling.
- Factory marriage (rarely, but occurs).
In such cases, the method of "thread" will help:
- Take a thin but strong thread (such as a tooth or fishing line).
- Slide it into the gap between the lid and the case at the USB-C connector.
- Carefully thread back and forth, as if "reduce" the adhesive layer.
- When the thread passes 2/3 of the perimeter, put the cover with a mediator.
⚠️ Attention: This method requires patience and precision, and if the thread slips and falls under the plume, it can cut it.
Phones with a severely deformed lid (for example, after a hit) may require partial deconstruction from the front, in which case it is better to contact the service, since the risk of damage to the display or touch screen is high.
