How to remove the battery from Xiaomi Redmi 5: instructions with photos and warnings

Introduction: Why you might need to remove the battery

The battery in Xiaomi Redmi 5 is not just a power source, but a key component that depends on the stability of the smartphone. Over time, even the best-quality batteries lose capacity, swell or stop holding charge. If your Redmi 5 suddenly turns off at 30% charge, overheats or deformed the back cover, it's time to think about replacing, but before that, you need to safely remove the old battery without damaging the motherboard or plumes.

Unlike the flagship models with removable covers, the Redmi 5 has a non-shatterable body, which complicates the process. Many users are afraid to disassemble the phone themselves for fear of breaking latches or breaking flexible cables. However, with the right approach and the availability of tools at hand, this task is quite feasible at home, the main thing is to follow a clear algorithm and avoid common mistakes, which we will discuss below.

In this article you will find:

• 🔧 Step-by-step instructions with photos and videos (if visual assistance is required).
• 🛠️ List of necessary tools - from mediator to hair dryer.
• ⚠️ Critical warnings that will keep you from short circuit or screen damage.
• 🔄 Alternative ways to retrieve if the battery is swelled or glued too much.

Preparation for disassembly: tools and security measures

Before you start disassembling the Xiaomi Redmi 5, make sure you have everything you need. The wrong tool is the main cause of damage to the body or internal components.

• 🔨 Plastic mediator or guitar mediator (metal blades scratch the body!).
• 🔥 Hair dryer or thermo-air station (for softening the glue, the temperature is not higher than 80)°C).
• ⚙️ Screwdriver. T3 or T4 (screw-cover).
• 🧲 Magnetic mat or container (to avoid losing small details).
• 🧴 Isopropyl alcohol 90%+ (glue-cleaner).
• 🔋 New battery (if you are planning a replacement, check for model compatibility) MDE6S).

Pay special attention to security measures:

⚠️ Attention! If the battery is swelling (the phone lid is raised), do not use a hair dryer - the risk of fire! In this case, the disassembly is better left to the service center. Also avoid mechanical blows to the battery - lithium-ion cells can ignite if damaged.

Before the start of the work:

1. Turn off the phone and remove it. SIM-map + memory card (if any).
2. Discharge the battery before 20-30% — This will reduce the risk of short circuits.
3. Work on a clean, well-lit surface (it is better to cover the table with a soft cloth).

Step 1: Removing the back cover of Xiaomi Redmi 5

The back cover of the Redmi 5 is mounted on latches and glue, so you need to remove it carefully so that the plastic fixtures do not break.

1. Heat the phone edge with a hairdryer (by 30 seconds on each side, at a distance 5-7 Do not direct the airflow to the screen or camera!
2. Insert the mediator into the gap between the lid and the case (start with the lower left corner where the SIM card is located).
3. Carefully drive the mediator along the edge, gradually snapping the latches. If the lid does not respond, warm up again.

Common mistakes at this stage:

• ❌ Too much pressure from the mediator → lid-crevice.
• ❌ Heating over 80°C → plastic deformation or damage to the glue under the battery.
• ❌ Attempt to remove the cover from the top (there are camera plumes and fingerprint scanner!).

Heated the hull around the perimeter.

A plastic mediator is used.

After removing the cover, you will see:

• 🔋 Battery (stick to the body).
• 📸 Camera module and fingerprint scanner (attached by plumes).
• 🔌 Battery connector (fixed with a small screw).

Step 2: Disconnect the battery from the motherboard

Before you try to tear the battery off, be sure to disconnect it from the board, which will prevent short circuits and damage to the components.

1. Find the battery connector (usually located at the top of the battery, next to the motherboard).
2. Unscrew the screw that fixes the connector (use a screwdriver). T3 or T4).
3. Carefully put a plastic spatula on the connector and unplug it. Don't pull the wires!

Important nuances:

• 🔌 If the connector is "stiff," don't use force. Put some isopropyl alcohol on it and wait. 1-2 minute.
• 🔍 Check if there are any small parts near the connector (like capacitors) that are easily hit with a screwdriver.

⚠️ If you accidentally close contacts on the board (for example, with a screwdriver), immediately disconnect the phone from charging and do not turn it on. 10-15 It could save the motherboard from burning out.

After turning off the battery, it is recommended to wait 5 minutes - this will discharge the residual voltage in the capacitors.

💡

If you plan to stay away from a battery for a long time (for example, to repair a board), seal the battery connector with a tape, which will prevent the contacts from accidentally closing.

Step 3: Removing the battery from the housing

The battery in Xiaomi Redmi 5 is glued to the body with double-sided tape or special glue, it takes patience and accuracy to remove it. There are two main methods:

Method 1: With filament (for intact batteries)

1. Tap the battery from any angle with a plastic spatula to create a gap.
2. Squeeze a thin nylon thread under the battery (for example, from guitar strings or fishing line).
3. Carefully saw the thread under the battery, cutting off the glue. Go from one edge to the other.

Method 2: Heating + shoulder blade (for bloated batteries)

1. Heat the body in the battery area with a hairdryer (temperature — 60-70°C).
2. Insert a plastic blade under the battery and slowly lift it, separating it from the glue.
3. If the battery fails, repeat the heat. Don't use excessive force!

What can't be done:

• ❌ Using metal objects (knives, screwdrivers) - the risk of puncturing the battery.
• ❌ Pressing on the center of the battery – this can lead to an internal short circuit.
• ❌ Sharply pull the battery - damage the plumes or connectors on the board.

💡

If the battery is swelling, it should not be punctured or bent. Lithium-ion batteries, when damaged, emit toxic gases and can ignite.

Step 4: Cleaning the case after the battery is removed

After the battery is removed, the case will remain glue traces, dust and possible metal sawdust. Don't ignore this stage - the cleanliness of the insides of the phone directly affects its further operation.

For cleaning, you will need:

• 🧴 Isopropyl alcohol (to remove glue).
• 🧻 Wormless napkin or microfibre.
• 🪥 Toothpick or wooden stick (for hard-to-reach places).

Procedure:

1. Moisten the napkin with alcohol and gently wipe the place where the battery was glued.
2. Remove the glue residues with a toothpick (do not scratch the body!).
3. Blow the body with compressed air (such as a canister to clean machinery) to remove dust.
4. Check the battery connector on the board - clean it with alcohol if necessary.

If you are planning to install a new battery, it is recommended to use a new two-way Scotch (e.g., a new two-way Scotch, 3M 9448A). Old glue loses its properties and does not provide reliable fixation.

Frequent problems and their solutions

Even with a careful disassembly, there can be unexpected complications, and here are the most common problems and ways to fix them:

Problem 1: The battery does not disconnect from the board

If the connector is "stuck" or deformed:

• 🔧 Carefully swing the connector to the sides with a plastic shovel.
• 💧 Put the alcohol on the base of the connector and wait. 1-2 minute.
• 🔥 Heat the connector area with a hairdryer (no higher than 60) easily.°C).

Problem 2: The phone lid is cracked

If there are cracks when removing the cover:

• 🛠️ Close the cracks with transparent tape (temporary solution).
• 🔍 Check if the dust has entered the body.
• 📱 Consider the option of replacing the cover (cost - from 500 rubles).

Problem 3: The phone doesn't turn on after assembly

If after installing a new battery, the phone does not respond to the power button:

• 🔋 Check if the battery connector is properly connected.
• 🔌 Connect your phone to the charger on 10-15 Minutes (sometimes it takes time to wake up the power controller).
• 🔧 If it doesn’t help, the fee may be damaged (diagnosis is needed).
