Removing the battery from the Xiaomi Redmi smartphone is a challenge that owners face when replacing the battery, repairing after a fall or restoring the device after moisture hits. Unlike older models with removable covers, modern Redmi (for example, the Note 11 Pro, Redmi 10 or Redmi 9T) have a non-shatterable case where the battery is glued to the rear panel, which complicates the process, but does not make it impossible for a user with minimal skills.
Many people are afraid of damaging plumes or crushing the battery, which can lead to fire. Indeed, lithium polymer batteries are sensitive to mechanical stress, but with the right approach, the risks are minimized. In this article, we will figure out what tools you need, how to prepare the phone, and Step-by-step, go through the entire process from unscrewing the screws to safely removing the battery. You will also learn which Redmi models require special attention, and where you can do without professional equipment.
If you've never taken a smartphone apart, don't rush to work: some steps (like unplugging the display plume) require care, but for most users, the task is quite doable - the main thing is to follow the instructions and not miss important nuances.
What tools will be needed to remove the battery
Without the right tools, it’s almost impossible to remove the battery from the Xiaomi Redmi.
- 🔧 Set of screwdrivers (cross-haul) PH00, flat 1.5 mm, five-pointed Y00 for some).
- 📱 Plastic mediators or blades to disengage the body (metallic can scratch the frame).
- 🔥 Dryer or thermo-air station (to soften the glue under the battery; temperature 60–80)°C).
- 🧲 Suction (helps to raise the screen after heating).
- 🔋 Special thrusts for the battery (or a thin guitar string / plastic card in extreme cases).
- 🛠️ Tweezers (for working with small details and plumes).
Redmi models with waterproof housing (such as Redmi Note 12 Pro+) will require a sealant to reassemble. If you plan to replace the battery yourself, buy an original or certified part in advance - cheap counterparts can swell or quickly fail.
⚠️ Warning: Do not use knives or sharp objects to tamper with the battery! Lithium polymer batteries can ignite or explode when punctured or compressed. Always work with plastic or wooden tools.
Preparing the phone for disassembly
Before you start removing the battery, you need to properly prepare the device:
- Turn off the phone and remove it. SIM-If the battery is swelling, don't turn it on, it's dangerous!
- Discharge the battery to 20-30%, a fully charged battery is more dangerous when mechanically exposed.
- Remove the back cover (if it is removable like the Redmi 9A). Most modern models have the cover glued to heat it with a hair dryer around the perimeter (don't direct air flow to the screen!).
- Unscrew all the screws on the back. In some models (for example, the Redmi Note 10 Pro), the screws are hidden under the stickers - they need to be carefully tampered with.
If you're taking down the phone from OLED-screen (e.g. Redmi) K50), Be careful: the plume of the display is very fragile. It is better to watch the video disassembly of your model in advance - the location of screws and plumes may differ.
💡
Before heating the body with a hairdryer, stick paint tape on the screen - this will protect it from accidental scratches when working with a mediator.
Step-by-step: how to remove the battery from Xiaomi Redmi
Now, to the most critical stage, follow the instructions in strict order.
- Disconnect the battery plume from the motherboard. It's usually under a metal cover that needs to be unscrewed. Use a plastic blade to gently lift the connector.
- Heat the battery with a hair dryer for 2-3 minutes, holding the device at a distance of 5-10 cm. The glue under the battery should become soft. Do not overheat - temperatures above 80 ° C can damage the board!
- Put a plastic card or special traction on the battery. Start at the edge where there are no components. If the battery doesn't respond, heat it up again.
- Carefully pull the battery up without bending it. If the glue is too strong, use isopropyl alcohol (a few drops around the edges will help dissolve the glue).
Redmi Note 11 and newer models often have a particularly strong battery glue, which may require a guitar string to be passed under the battery and sawed off the body, which requires skill, so if you're not sure, you'd better contact the service.

⚠️ Warning: If the battery starts to hiss, smoke, or heat up when you remove it, immediately place it on a non-combustible surface (such as ceramic tiles) and move away to a safe distance!
Features of battery removal on popular models Redmi
The design of the battery and its mounting may vary depending on the model, and the table below contains key nuances for the most common Xiaomi Redmi smartphones:
| Model | Type of battery attachment | Difficulty of extraction | Features |
|---|---|---|---|
| Redmi Note 12 Pro/+ | Glue + metal frame | ⭐⭐⭐⭐ | Heat to 70°C, battery plume hidden under the screen, risk of camera damage if sloppy extraction. |
| Redmi 10C / 10A | Glue (weak) | ⭐⭐ | The battery is removed easily, but the back cover is fragile - be careful with the latches. |
| Redmi 9T / 9 Power | Glue + bilateral scotch | ⭐⭐⭐ | Screws under the stickers, battery plume soldered - you need to solder off or gently tear off. |
| Redmi K50 / K60 | Glue + graphite pad | ⭐⭐⭐⭐⭐ | Complex design, experience required, battery traction recommended. |
For Redmi models with fast charging (33W and above), be especially careful: their batteries often have additional controllers that can be damaged if you carelessly handle. If after removal you notice a bloating or deformation of the battery, it can not be installed back - only recycling!
What to do if the battery is too tight?
Frequent Mistakes and How to Avoid Them
Even experienced users sometimes make mistakes when removing the battery, and here are the most common ones and ways to prevent them:
- 🔌 Damage to battery plume when disconnected. Always use a plastic blade, not a metal screwdriver.
- 🔥 Hold the device at a distance of 10 cm and do not heat one point longer than 10 seconds.
- 💥 Puncture the battery with a sharp object. If the battery fails, heat it again or use traction.
- 📱 Damage to the flexible display plume when the battery is lifted.
- 🔋 Use of force in extraction: Lithium polymer batteries do not tolerate bending - they can catch fire.
One of the most dangerous mistakes is trying to rip out the battery without heating, which can cause the contact pad on the board to break off, and then the phone will not turn on, and if the glue is too strong, it is better to spend an extra 10 minutes warming up than risk expensive repairs.
💡
If the battery is swelling, do not try to "press" it or puncture it! Bloating means that gases have accumulated inside, and any mechanical action can lead to an explosion.
What to do after removing the battery
So, you got the battery out? Great, but it's not over. Here's what we need to do next:
- Clean the case of glue residues. Use alcohol and cotton swabs. Don't rub too hard, you can damage the antenna lines.
- Check the new battery for no defects. Xiaomi's original batteries have a hologram and serial number.
- Set the battery on double-sided tape or special glue. Don't use superglue - it could damage the board in future repairs.
- Put the plume on, make sure all the connectors are tight, turn on the phone and make sure it's charging.
If you have replaced the battery but the phone is not turning on or is quickly discharged, the following reasons are possible:
- Poor contact of battery plume (check connector).
- Non-original battery (may have a smaller capacity).
- Damage to the power controller on the board (diagnosis is required).
After replacing the battery, it is recommended to calibrate it: completely discharge the phone, then charge to 100% without interruption. Repeat the process 2-3 times - this will help the system to correctly determine the level of charge.
When is the best time to contact the service center
Despite the fact that you can remove the battery from Xiaomi Redmi yourself, in some cases it is better to trust the professionals:
- 🔧 If you have a model with a complex design (for example, Redmi). K60 Pro or Note 12 Turbo).
- 💦 If the phone hit the water - corrosion on the board can complicate repairs.
- 🔥 If the battery is swelled or deformed, the risk of fire is too high.
- 📱 If you have never taken out electronics and are afraid of damaging plumes.
The cost of replacing a battery at a Xiaomi service center or an authorized workshop is usually 1,500-3,500 rubles (depending on the model), which is not so expensive when you consider the risks of damaging the phone during self-repair, and you will be given a guarantee for work and parts.
⚠️ Warning: If after self-replacement of the battery the phone stopped turning on or artifacts appeared on the screen, do not try to re-disassemble it without diagnosis.
