How to get a battery from Xiaomi Redmi Go: disassembly, tools and precautions

Xiaomi Redmi Go is a budget smartphone of 2019, which is still used by many users. However, over time, the battery loses capacity, inflates or needs to be replaced. Unlike modern models with non-removable batteries, Redmi Go theoretically allows you to remove the battery, but the process requires caution. In this article, a detailed analysis of what tools you will need, how to avoid damage to the board, and what to do if the battery is “stuck” to the case.

It's important to understand that removing the battery breaks the tightness of the case and can lead to loss of water protection (if any), and that doing the wrong thing can short circuit or damage the plumes. If you're not sure about your skills, you should contact the service center. But if you decide to act on your own, follow our instructions with all the nuances.

Preparation for disassembly: tools and conditions

Before you start, make sure you have everything you need. Xiaomi Redmi Go does not require professional equipment, but without the right tools, the risk of damage increases significantly.

• 🔧 Plastic blades (or mediators) - for careful lid slinging and battery disconnection.
• 🔨 Cross screwdriver (size) PH00) — for screws on the back.
• 🧲 Magnetic mat or container – to avoid losing small details.
• 🔥 Hair dryer or thermo-air station - if the battery is glued (optional).
• 🧴 Isopropyl alcohol (90%+) — cleaning contacts after removal.
• 📦 New battery (if you are planning to replace it) – check the compatibility of the model BM47.

Also, prepare your workspace, which should be well lit, free of dust and static electricity, work on a flat table, or better, on an antistatic mat, and if the battery is swelling, don't use metal tools to swell it, the risk of puncture and fire is extremely high.

Tip: If you don't have experience, practice on a non-working device or watch Redmi Go video demos on YouTube. Pay attention to the location of the plumes and screws - they may vary depending on the batch.

Step 1: Shutting off power and removing the back cover

The first and most important step is to completely shut down the smartphone, and even if the device is off, the capacitors can still have a charge, so that you don't short-circuit.

1. Turn off Xiaomi Redmi Go long hold power button.
2. Extract. SIM-card and memory card (if installed).
3. Wait 10-15 minutes - this will discharge the residual currents.

Now you can start removing the back cover. On Redmi Go, it's mounted on latches and two screws under plugs.

• 🔍 Find two screws at the bottom of the case (near the Micro-USB connector).
• 🔧 Carefully unscrew them with a cross screwdriver.
• 🕳️ Insert a plastic spatula into the gap between the lid and the case (start with the bottom corner).
• 🔄 Swipe the shoulder blade around the perimeter, alternately cracking the clamps.

⚠️ Attention: Don't put too much effort - the latches are fragile! If the lid doesn't lend itself, check if all screws are unscrewed. Some versions of the Redmi Go may have a hidden screw under the camera sticker.

Step 2: Unconnecting the plumes and accessing the battery

Once you remove the lid, you'll see the insides of the smartphone. The battery in Xiaomi Redmi Go is located at the top and glued to the body.

1. Disconnect the battery plume from the motherboard, and it's under a black protective film.
2. Carefully tuck the connector with a plastic spatula and push it aside.
3. Check if there are any additional mounts (sometimes the battery is fixed by a metal plate).

⚠️ Warning: If you see signs of oxidation or corrosion on the battery contacts, do not continue disassembling! This is a sign of moisture getting in, and further manipulations may lead to a short circuit.

If the battery is blown up, it can't be pierced or bent.

1. Wear safety glasses and gloves.
2. Place the device in a refractory container (such as a metal bowl).
3. Carefully tuck the battery with a plastic spatula, avoiding sudden movements.

💡

If the battery does not disconnect, try to slightly heat the case with a hairdryer (temperature not higher than 60).°C) This will soften the glue, but don't overheat the board!

Step 3: Battery Removal – Methods and Risks

The battery in Redmi Go is glued to the body with double-sided tape, and there are several ways to remove it, but not all of them are safe.

Method 1: Plastic shoulder blade + isopropyl

The most gentle way, but requires patience:

1. Apply a few drops of isopropyl alcohol under the edge of the battery (it dissolves the glue).
2. Wait 2-3 minutes.
3. Carefully tuck the battery with a plastic spatula, gradually moving along the body.

Method 2: String or guitar string

Suitable if the glue is very strong:

1. Push a thin nylon thread or string under the battery.
2. Carefully "saw" it back and forth, separating the battery from the body.
3. Don’t pull too hard – you can break the plumes.

Method 3: Heating (emergency)

Used if other methods do not help, but are risky:

1. Heat the body with a hair dryer (temperature to 60)°C) within 1-2 minutes.
2. Try to put a spatula on the battery.
3. If it does not help, repeat the heating, but do not allow the fee to overheat!

⚠️ Warning: If the battery starts to smoke, hiss or heat up above 70°C -- immediately stop the manipulation, take the device outside and wait for the cooling!

Step 4: Install a new battery (if required)

If you have removed the battery for replacement, follow these rules when installing a new one:

• 🔋 Check Compatibility: Original Battery for Redmi Go Is Labeled BM47 and a capacity of 3,000 mAh.
• 🧹 Clean the contacts on the board and the new battery with a cotton swab soaked in isopropyl alcohol.
• 📏 Make sure that the new battery fits tightly into the groove - without gaps and distortions.
• 🔌 Connect the plume to the board before the final battery fixation.

To fix the new battery, use a double-sided scotch 3M (Don't use superglue or other aggressive adhesives, which can damage the board the next time you disassemble.

After installation:

1. Connect the battery plume to the board.
2. Make sure all contacts are in contact.
3. Close the back cover and twist the screws.
4. Turn on your smartphone and check the charge (should show 0-1% and start charging).

💡

Never turn on a smartphone with the battery disconnected – it can burn the power controller!

Frequent Mistakes and How to Avoid Them

Even experienced users sometimes make mistakes when retrieving the battery, and here are the most common ones and ways to prevent them:

Another common problem is that the flexible plume of the display is damaged, and it passes next to the battery, and if you move it carelessly, it's easy to break.

• Before removing the battery, inspect the location of the plumes.
• Do not press on the right side of the case (there is a plume of the screen).
• If the plume is still damaged, it can be replaced, but it requires soldering.

When should I contact the service?

Although the Xiaomi Redmi Go is relatively easy to disassemble, there are situations when self-repair is impractical or dangerous:

• 🔥 Battery will rise by more than 5 mm - a high risk of fire.
• 💧 On the board, traces of corrosion or oxidation are visible (infection of moisture).
• 🔌 After the battery is removed, the smartphone does not turn on even with a new battery.
• 🛠️ No experience with electronics – errors can cost more than repairs in the service.

The cost of replacing the battery in Xiaomi service centers is from 1,500 to 2,500 rubles (2026), depending on the region. If you doubt your abilities, it is better to pay for professional work than risk the device.

⚠️ Attention: If after replacing the battery, the smartphone began to overheat, quickly discharge or spontaneously turn off - this is a sign of a malfunction of the power controller.
