How to remove the battery from Xiaomi Redmi 6A: disassembly of the case and safety tips

Introduction: Why you may need to remove the battery

The battery in the Xiaomi Redmi 6A is one of the key components that loses capacity or fails over time. Unlike flagship models, where the battery is often soldered to the motherboard, the budget Redmi 6A is removable but attached to double-sided tape. This makes it easier to replace, but requires care: improper extraction can damage the plumes, connectors or the case itself.

The reasons for disassembling the battery range from the banal bloating of the battery (which is dangerous for the device!) to the need for a complete disassembly to repair the display or motherboard. In some cases, users remove the battery to reset the settings through testpoints if the smartphone does not respond to buttons. However, without experience, it is easy to make mistakes - for example, to tear a flexible plume or leave microparticles of glue on the board.

Preparation: security tools and measures

Before you start disassembling, make sure you have everything you need. Xiaomi Redmi 6A does not require professional equipment, but without the right tools, the process will turn into anguish.

• 🔧 Plastic blade (or mediator) - to separate the back cover.
• 🔨 Cross screwdriver (PH00 or PH0) — hull-rotor.
• 🧲 Magnetic mat or container – to avoid losing small details.
• 🔥 Hair dryer or thermo-air station - for softening the glue (optional).
• 📦 Screen suction cup – will help with the front panel compartment if required.

Important: Redmi 6A It does not have official protection from moisture (IP-Certifications, but there may be dust and debris inside the case, and work on a clean, well-lit surface, and if the battery is blown up, don't puncture it or heat it above 60.°C: This can cause a fire or explosion.

⚠️ Warning: If the smartphone was in water or was hit, before disassembling be sure to disconnect it from charging and wait for the full discharge of the battery (up to 0.

Step 1: Removing the back cover

The Redmi 6A is latched and glued together, so you need to open it carefully. Start by heating the edge of the lid with a hair dryer (~50°C) for 1-2 minutes, which will soften the glue.

1. Insert a plastic blade into the gap between the lid and the body at the headphone jack.
2. Carefully drive the blade along the edge, alternately snapping the clamps. Don't force it -- if the lid doesn't lend itself, warm it up again.
3. After separation of the upper part, remove the lid completely, starting from the lower edge (there are no plumes there).

Under the lid, you'll see the battery, the motherboard and the plumes. Don't pull the lid too hard, it might get a protective film or parts of double-sided tape. If the lid cracks, don't panic: it can be replaced — MB015ZM).

Step 2: Disconnect the battery plume

Before you take off the battery, be sure to disconnect it from the motherboard.

1. Find the battery connector on the board - it is located near the lower edge of the battery andmarked as BATTERY CONNECTOR.
2. Carefully slap the connector with a plastic spatula, pulling up. Don't use metal tools - they can close the contacts!
3. Make sure the connector is completely out of the nest. If it's stuck, swing the spatula slightly left and right.

After disconnecting, check the multimeter voltage at the battery terminals (if you have experience). Normally, it should be 3.7-4.2V. If the voltage is below 3.0V, the battery is deeply discharged and may not turn on after connecting - you will need to "reanimate" the charger with the boost function.

⚠️ Warning: If you turn off the connector, sparks or the smell of burning, stop disassembling immediately. This is a sign of a short circuit on the board - further manipulations may damage the power controller.

Step 3: Removing the battery

The battery in the Redmi 6A is attached to double-sided tape, which eventually loses its stickiness, but can still resist.

1. Tap the edge of the battery with a plastic spatula or a special sucker for batteries.
2. Pull up slowly, evenly separating the battery from the case. If the tape does not respond, heat it with a hair dryer (no more than 60 ° C!).
3. Do not pull the battery out with a jerk – there may be antenna or vibration motor cables underneath.

If the battery is swelling, it should not be bent or pressed.

• 🛑 Do not use metal tools - the risk of puncture!
• 🔥 Work in gloves and safety glasses.
• 🚮 Dispose of the bloated battery in special reception points (do not throw it into the trash!).

💡

If you have glue in your place after removing the battery, remove it with isopropyl alcohol (90%+) and a cotton swab, which will make it easier to install the new battery and prevent overheating.

Step 4: Installation of a new battery

Before installing a new battery, inspect the connector on the motherboard, and if the contacts are oxidized or contaminated, clean them with pencil eraser or alcohol.

1. Remove the protective film from the new battery (if any).
2. Stick bilateral tape on the case (usually it comes complete with a battery).
3. Connect the battery connector to the board and gently put it in place, pressing the edges.
4. Make sure the plumes are not clamped or twisted.

After installation, turn on the smartphone and check:

• 🔋 Charging is stable (without current surges).
• 📱 The device does not overheat in the battery area.
• 🔄 The percentage of charge is displayed correctly (without jumps).

⚠️ Warning: If the battery is discharged in a few hours after the replacement, or the smartphone is turned off at 20-30% charge, there may be a problem with the power controller on the motherboard.

💡

The new battery may have an incorrect percentage for the first 2-3 charge cycles. That's OK -- the controller needs time to calibrate. Charge the phone to 100% and discharge to 0% the first two times.

Frequent Mistakes and How to Avoid Them

Even experienced users sometimes make mistakes when replacing the battery.

• 🔌 Forgetting to turn off the battery connector before retrieving - this can lead to a short circuit.
• 🔥 Overheat the body with a hair dryer - the plastic is deformed, and the glue can dry even more.
• 🛠️ Use a knife or screwdriver instead of a spatula - this scratches the body and damages the plumes.
• 📉 Install a battery with a smaller capacity – Redmi 6A Requires a battery of 3000 mAh (original - 3100 mAh).

If the smartphone does not turn on after replacement, check:

1. Is the battery connector plugged in before the click.
2. Is the display plume damaged (sometimes it interferes with the proper fit of the battery).
3. Has the overdischarge protection worked (try holding the power button for 20-30 seconds).
