How to remove the battery from Xiaomi Redmi: instructions for all models

Removing the battery from Xiaomi Redmi is a challenge that users face when repairing themselves, replacing the battery or diagnosing malfunctions. Unlike older phones with removable covers, modern Redmi models (starting with Redmi Note 3 and later) have a non-shatterable body, where the battery is glued to the rear panel, which complicates the process, but does not make it impossible with the right approach.

In this article, we will take a step-by-step guide for different Redmi generations, list the tools you need and warn you of common errors that can damage the board or display, and focus on models with built-in batteries (such as the Redmi Note 10 Pro or Redmi 9T), where the risk of damage to the plumes is higher due to the compact layout.

If you've never taken a smartphone apart, don't rush to work. In some cases, such as a bloated battery, you'd better go to a service center, but if you're confident in your abilities, our recommendations will help you do it carefully.

What tools will you need

Removing the battery from Xiaomi Redmi will require a specialized set of tools, without which you risk damaging the body, plumes or the battery itself.

• 🔧 Plastic blades (mediators) - for tidying the lid and unplugging the plumes. Metal tools can scratch the body.
• 🔨 Screwdriver cross (PH00 or PH0) — for screws in the Redmi Note 8/9/10. In some models (e.g. Redmi). 7A) squirrel Y00.
• 🔥 Hair dryer or thermo-air station - to soften the adhesive that the battery is attached to the body. Optimal temperature: 60-80°C.
• 🧲 Screen suction cup – will help lift the display module in models with adhesive attachment (for example, Redmi Note 11).
• 🔋 Plastic tweezers – to extract flexible plumes and connectors of the battery.
• 🛡️ Antistatic bracelet (optional) – protects the board from static electricity.

If you don't have a hair dryer, you can use isopropyl alcohol (90%+) to dissolve the glue, but it's longer and less effective for highly glued batteries, and you can use a normal household hair dryer as a last resort, but keep your temperature under control so you don't melt the plastic parts.

⚠️ Warning: Don't use knives or screwdrivers to smack the battery! This can puncture the battery, causing fire or explosion. Lithium batteries are extremely sensitive to mechanical damage.

Preparing the phone for disassembly

Before you start removing the battery, you need to completely turn off the device and prepare the workplace.

1. Turn off your smartphone and remove it. SIM-card and memory card (if any) Wait until the phone cools if it was in use.
2. Remove the back cover (if it is removable, as in the Redmi 4A or Redmi 5A). In most modern models, the cover is glued, so it must be carefully tucked with a plastic blade, starting from the corners.
3. Disconnect the battery plume from the motherboard, which is usually located under a metal cover secured by 1-2 screws, and use tweezers to carefully remove the connector.
4. Fix the screws on a magnetic substrate or in a container – they are small and easily lost.

In Redmi Note 5/6/7 and later, the battery plume is often covered with black insulation tape, which must be carefully removed to access the connector. Don't pull the plume with force - it can break away from the board!

If you’re disassembling Redmi with an amoleed screen (like the Redmi K20 Pro), be especially careful: the display module in such models is often glued around the perimeter, and it’s easy to damage when sloppy lifting.

Step-by-step instructions for battery recovery

The process of removing the battery depends on the Xiaomi Redmi model, but the general scheme looks like this:

1. Warming up the glue

The battery in Redmi is glued to the body with double-sided tape or special glue, so to loosen the grip, you need to heat the back of the phone:

• 🔥 Set the hair dryer at a temperature of 60-80°C and evenly warm the back cover for 2-3 minutes.
• 🔄 Pay special attention to the edges of the battery - there the glue usually holds stronger.
• ⚠️ If the case gets too hot, let it cool for 1-2 minutes.

Battery tampering

After heating, gently tuck the battery into a plastic spatula or a special tool to remove the batteries. Start at the edge where there are no plumes:

• 📍 In the Redmi Note models 8/9 It is more convenient to start from the upper left corner (near the camera).
• 🔧 At Redmi. 6/7 Battery can sit tighter – use two blades for even lifting.
• 🚫 Don't use force. If the battery doesn't respond, warm up the glue again.

In some cases, there may be traction tapes under the battery (e.g., in the Redmi Note 10).If there are, pull them carefully to separate the battery from the case.

3. Full extraction

When the battery is separated from the body by 2-3 mm, you can continue its extraction:

• 👆 Lift the battery over the edge and slowly pull it out at a 30-45 angle.°.
• 🔌 Make sure the plume is not stretched - it can come off!
• 🧹 After extraction, clean the case of glue residues with isopropyl alcohol.

⚠️ Warning: If the battery is swelling (seen by the convex back cover), don't try to remove it yourself! The risk of fire or battery rupture is extremely high.

Features for different models Xiaomi Redmi

The battery design in the Redmi range varies by generation, with key nuances for popular models below:

Redmi Note 11/12 and later often use a graphene battery, which is thinner and lighter but more brittle. Avoid bending when extracted - this can lead to an internal short circuit.

If you replace the battery with a new one, look at the capacity and model. For example, for the Redmi Note 10 Pro, the original battery is labeled BM4X and has a capacity of 5020 mAh. Installing a non-original battery can lead to rapid wear and tear or overheating.

Common Mistakes and How to Avoid Them

Even experienced craftsmen sometimes make mistakes when removing the battery from the Xiaomi Redmi, and here are the most common mistakes and ways to prevent them:

• 🔌 Damage to battery plume occurs when you snatch a sharp snatch. Always unplug the connector until Attempting to lift the battery.
• 🔥 Overheating of the body - if you use a hair dryer at maximum temperature, plastic clips or plumes can melt. Keep the temperature between 60 and 80°C.
• 💥 Puncture of the battery - metal tools or excessive force can pierce the lithium cell. Use only plastic blades.
• 🔧 Loss of screws – Redmi uses screws of different sizes. Sort them by groups (e.g., cover, board, camera).
• 📱 Display damage – in models with adhesive screen (for example, Redmi Note) 10S) with careless lifting, you can break the plume of the touch screen.

Critically, if the phone stops turning on after the battery is removed, check the power supply with a multimeter. Often the problem lies in a damaged connector or a fuse on the board (usually marked F1 or F2).

Another common mistake is to use the wrong adhesive when installing a new battery. Don't use superglue or scotch! Only two-way adhesive for smartphones (e.g. 3M 9448A or similar) is suitable for fixing the battery.

What to do after removing the battery

When the battery is successfully removed, several steps must be taken to make sure that the preparation for the new one is completed without any problems:

1. Clean the case of glue residues. Use isopropyl alcohol and a lilac-free wipe. Don't scratch the case with metal objects.
2. Check the connector on the motherboard, and if it's contaminated or oxidized, clean it with a contact eraser or alcohol.
3. Set the new battery in reverse sequence, make sure the plume is securely locked in the connector.
4. Check the health before final assembly. Connect the phone to charge and make sure it turns on.

If you notice that the new battery is rapidly discharged or overheating, the following reasons are possible:

• 🔋 Unoriginal battery of low quality.
• 🔌 Bad contact in the connector (check if the plume is bent).
• 📱 Software failure (reset settings via Settings) → Recovery and discharge).

⚠️ Warning: After you change the battery, calibrate it for the first 3 charging cycles. Charge the phone to 100%, then discharge to 0% (until it turns off.
