Xiaomi Redmi 5 is a popular smartphone of 2017, which is still used by many users. However, over time, the battery loses capacity, swells or needs to be replaced. If you are faced with the need to remove the battery from this device, it is important to do it correctly so as not to damage the board, plumes or body. Unlike modern models with non-removable batteries, Redmi 5 theoretically allows you to dismantle the battery, but the process requires accuracy and special tools.
In this article, you'll find step-by-step instructions with a photo, a list of tools you need, and critical warnings to avoid common mistakes, and we'll learn how to open the back cover, unplug the plumes, and safely remove the battery, even if it's swollen or glued to the case. And if you've never taken your smartphone apart, don't worry: even a beginner can handle our tips.
Preparation for disassembly: tools and security measures
Before you start removing the battery, make sure you have everything you need, and the wrong tools can damage the body, the plumes, or even cause a short circuit.
- 🔧 Plastic blade (or mediator) - to separate the cover without scratches.
- 🔨 Cross screwdriver (size) PH00 or PH0) — screw-hole.
- 🧲 Suction - will help to lid the lid if the glue is too strong.
- 🔥 Hair dryer or thermo-air station - for softening the glue (optional, but useful).
- 🧤 Gloves – protection against cuts and static electricity.
- 📦 Container for screws - so as not to lose small details.
Also, prepare the workplace: a clean, well-lit surface with no carpets or fabrics that can electrify. If the battery is swelling, don't use metal tools to extract it, the risk of puncture and fire is extremely high, and then you should contact the service center.
⚠️ Attention: If the battery is deformed (swelled, leaked), do not try to remove it yourself. Lithium batteries in this state can ignite when exposed to mechanical action!
Step 1: Turn off your smartphone and remove the back cover
The first step is to completely shut down the power. Even if the smartphone is dead, press the power button on the power button. 10-15 Just a second to make sure there's no residual charge, then start removing the lid:
- Place the Xiaomi Redmi 5 screen down on a soft surface (like a napkin).
- Heat the edge of the back cover with a hair dryer (temperature) ~50-60°C) during 1-2 It'll soften the glue.
- Insert a plastic blade into the gap between the lid and the body (start at the bottom edge where the charging connector is).
- Carefully drive the blade along the perimeter, separating the lid. If resistance is strong, warm up the problem area again.
The Redmi 5 lid is attached to glue and latches, so don't pull it by force, it can damage the plastic clips. If the lid doesn't lend itself, use the suction cup to create the initial gap.

Step 2: Disconnect the plumes and batteries
When you take the lid off, you'll see the battery covered in black film, so don't pull the battery right away, you'll need to disconnect the plumes first.
- Unscrew 10 screws (PH00 size) fixing the metal plate over the battery.
- Remove the plate and put it aside (screws are better folded in a container, so as not to confuse).
- Carefully slap the battery plume with a plastic blade and unplug it from the connector on the board. Use the photo below for a landmark:
If the plume doesn't detach, don't use force, check if there are any additional locks. On some versions of Redmi 5, the connector can be taped.
⚠️ Warning: After the battery plume is turned off, do not touch the board with your bare hands. Static electricity can damage the chips. Use an antistatic bracelet or periodically touch a grounded metal object.
Step 3: Removing the battery
Now, to the most critical point, the battery in the Xiaomi Redmi 5 is glued to the body, so it needs to be carefully separated. Here's how to do this:
- If the battery is not swollen, put a plastic spatula on the side and slowly pull it upwards, and the glue should stretch, not tear.
- If the battery is too glued, use isopropyl alcohol (90%+) or a special solvent for glue. Apply a few drops under the battery and wait 1-2 minutes.
- For bloated batteries, use a nylon thread (like a guitar string) and put it under the battery and saw the glue back and forth, as shown in the video:
If the battery fails, don't use metal tools - the risk of puncture and leakage of the electrolyte is too high.
💡
If the glue is left on the case after the battery is removed, remove it with alcohol or acetone.Do not use sharp objects - they can scratch the board.
Table: Comparison of battery recovery methods
| Method | Pluses | Cons | Recommendations |
|---|---|---|---|
| Plastic spatula | Safe for the battery. | Long if the glue is strong | Suitable for undamaged batteries |
| Nylon thread | Effective for bloated batteries | It requires skill. | Use with caution so as not to damage the fee |
| Isopropyl alcohol | It softens the glue in minutes. | We have to wait for drying out. | Apply point-by-point, avoiding hitting the board |
| Thermo-air station | Fast-softening glue. | Risk of overheating fees | Temperature not higher than 60°C, keep at a distance of 10 cm |
What to do after the battery is removed?
When the finalmente battery is removed, check it for damage.
- 🔋 Dispose of it in a special reception point (do not throw it into the garbage!).
- 🔥 Has traces of oxidation - check the board for short circuits.
- 🔌 Whole, but discharges quickly - you can install a new battery (for example, BL-5A 3300mAh).
Before installing a new battery, clean the contacts on the board and connector with alcohol. Make sure the new battery is compatible with the Redmi 5 - counterfeits can not only hold the charge poorly, but also damage the power controller.

- 💥 Battery puncture – Never use a knife or screwdriver to separate the battery.
- 📱 Bending the board - do not press it when removing the battery.
Another common problem is the glue residue on the board, and if left unchecked, the new battery may lie unevenly, causing overheating or poor contact, and use isopropyl alcohol and cotton swabs to clean.
(1) Correct connection of the battery plume.
(2) Damage to the board (blackened areas, chipped).
3) Charge of new battery (possibly discharged).-->
