How to remove the battery on Xiaomi Redmi 5

Xiaomi’s Redmi 5 series has proven to be reliable, metal-based and battery-powered, but over time, any lithium-ion battery loses capacity, causing rapid discharge and sudden shutdowns. Unlike today’s glass-covered models, replacing the battery requires more careful preparation and precision when working with the metal case.

The battery replacement procedure is a mid-range repair that can be done at home with basic tools. You'll need not only a new battery, but also a set of screwdrivers, as well as special suction cups to neatly open the case without damage. It's important to understand that improper disassembly can damage the plumes or lead to short circuits.

In this article, we will take a look at every step of the process, from the workplace preparation to the final test of the device’s health, learn how to safely unplug plumes, how to unplug an old battery, and how to avoid common mistakes that beginners often make when first repairing.

Tools and workplace preparation required

Before starting to disassemble the Xiaomi Redmi 5, you need to organize a clean and well-lit workplace. Dust and static electricity are the main enemies of electronics, so it is recommended to use an antistatic mat or just clean cotton fabric.

To successfully replace your battery, you’ll need a standard toolkit, which you can buy from any electronics store or marketplace.The lack of specialized tools can damage plastic latches or screws.

• 🛠️ Precision screwdrivers (cross-haired) PH000 flat).
• 🧲 Magnetic mat or screw sorting container.
• 🧲 Plastic blade (mediator) for opening the body.
• 🔥 Hair dryer or heating platform for softening glue.
• 🧲 Suction cup for careful pulling of the cover.

Pay special attention to the choice of a new battery. The market is full of low-quality copies that can swell or fail in a month. Look for original parts or proven analogues from well-known brands with a capacity of 3300 mAh, corresponding to the specification of the model.

⚠️ Warning: Never use metal tools to lid or disable plumes.The metal can damage insulation or short circuit the board, which will lead to irreversible consequences.

Primary safety measures and power outage

The first and most important step before any electronics disassembly is to shut down the device completely. In the case of Redmi 5, this is critical, since accidentally closing the battery contacts on the board while running can burn the power controller.

If the device turns on but discharges quickly, try to keep the battery to a minimum (about 5-10%) before starting work, which will reduce the risk of fire or bloating when mechanically impacting the cell. If the phone is not already turning on, just make sure it is not connected to the charger.

Work in low-humidity environments. High humidity can lead to oxidation of contacts immediately after opening the case, especially if the room is cool, and it is also recommended to remove metal jewelry such as rings or bracelets from your hands to avoid accidental contact with the board.

• 🔋 Take it down. SIM-Memory card before starting work.
• 🔋 Make sure your smartphone is completely off (not in sleep mode).
• 🔋 Put all tools within reach so as not to reach through the disassembled device.

Removal of the Redmi 5 Rear Cover

The metal body of the Xiaomi Redmi 5 is held on two screws at the bottom and around the perimeter on plastic latches. Unlike adhesive structures, there is no adhesive layer throughout the area, but the latches sit very tightly. There are two visible screws at the bottom, on the sides of the Micro-USB charging connector.

Unscrew the bottom screws with a PH000 screwdriver. After that, warm the perimeter of the device. Use a hairdryer by heating the edges of the body for 1-2 minutes. The temperature should not exceed 80-90 degrees so as not to damage the display or internal components. The plastic holding the antenna inserts should become softer.

Put a suction cup on the bottom of the back cover, closer to the edge, and gently pull up, creating a small gap. Insert a plastic blade or mediator into this gap. Don't try to swipe the tool around the perimeter at once; move gradually, snapping the locks in short areas.

⚠️ Attention: When you snap the body at the top of the smartphone, next to the main camera module, be very careful. There are plumes that can be damaged by sloppy movement of the shoulder blade.

Dismantling internal components and access to battery

When you remove the back cover, you'll see the interior of the smartphone, and most of the space is occupied by a battery, but access to the battery connector and the screws is covered by a metal shield, and this plate is screwed with several screws of different sizes.

Unscrew all the screws that hold the metal protection. Fold them separately, because they can vary in length. A short screw screw screwed into a long hole can damage the motherboard. Once the plate is removed, you will have access to the battery connector and the display plumes.

The first thing you need to do is to disconnect the battery plume from the motherboard, use a plastic blade or nail to gently lift the connector upwards, don't pull the wires, only act on the hard part of the connector, and once the power is turned off, you can safely work with other components.

Now we can move on to extracting the battery itself. In Redmi 5, it's mounted on two strips of double-sided tape, and just trying to pull it out with your fingers will do nothing but deform the body, and you have to apply heat again.

Removing the old battery and installing a new one

Heat the battery area with a hair dryer on the back (through the lid removed or directly on the disassembled device, with care) The heat will soften the adhesive layer. Try using a suction cup by attaching it to the center of the battery and pulling it up while simultaneously swaying the element from side to side.

If the suction cup doesn't work, you can use a plastic card or a spatula carefully, sticking it under the battery, move slowly, trying not to damage the battery insulation with sharp edges, and there may be residues of old glue inside the case - they must be removed before installing a new cell.

Clean the seat with alcohol or degrease. Apply special B-7000 strips or double-sided electronics tapes to the new battery (if it doesn't have adhesive layer on it), set the battery up, press it for a few seconds to lock it, and plug the plume into the characteristic click.

💡

If the old battery is swelling, do not puncture it or bend it, remove it as carefully as possible, trying not to damage the shell, as the contents of lithium-ion cells are toxic and flammable.

Device assembly and initial start

Before you turn the screws and close the lid, you need to make sure that the system is working, plug the battery plume and press the power button, and if the screen catches fire and the Mi logo appears, then the connection is correct.

After a successful test, turn off the phone. Put a metal plate in place, making sure all the plumes are flat and not clamped. Twirl the protection screws. Then gently snap the back cover, starting at the top, and twist the two lower screws.

Turn the device on permanently. The first start after the battery change may take longer than usual. The system must calibrate the new battery. It is recommended to immediately put the phone on charge to 100% so that the power controller correctly determines the real capacity.

• 📱 Make sure the screen is working without artifacts after assembly.
• 📱 Check the operation of the vibrator and speakers.
• 📱 Monitor the heating temperature during the first hours of use.

⚠️ Warning: If the phone doesn't turn on or warms up in the battery area after assembly, immediately disassemble the device again.

💡

Quality cleaning of the landing place from old glue is a guarantee that the new battery will sit tightly in the case and will not shift when falling.
