Replacement of the battery on Xiaomi Mi 5: detailed instructions with photos and videos

The Xiaomi Mi 5, released in 2016, is still a popular smartphone due to its powerful hardware and compact size. However, after 7-8 years of operation, even the highest-quality battery loses up to 50-70% of capacity, which leads to rapid discharge, spontaneous reboots and “off” with 20-30% of charge. If your Mi 5 began to discharge in a couple of hours or refuses to turn on without charging, it’s time to replace the battery.

In this article, you will find step-by-step instructions for replacing the battery from each stage, a list of necessary tools, tips for choosing a quality battery and answers to frequent questions. We will also tell you how to avoid errors that lead to damage to the plumes or motherboard. If you have never disassembled a smartphone, do not worry: Mi 5 is a device with medium disassembly complexity, and if accurate, the procedure will take no more than 40-60 minutes.

Signs that it is time to change the battery

It's not always obvious that the battery is the problem, but here are the key symptoms that indicate critical battery wear:

• 🔋 The smartphone is running out of power. 2-3 hours with moderate use (social networks, messengers).
• 🔄 There are spontaneous reboots when 15-30% charge.
• ⚡ When connecting charging Mi 5 show 0% It is now in place, even though it has been “dead” before. 10-15%.
• 🔥 The body is noticeably heated in the battery area (especially when charging).
• 📉 In settings (Settings) → Battery → Battery condition) capacity shows less than 2000 mAh (original - 3000 mAh).

If at least 2-3 items from the list about your smartphone - a replacement battery is inevitable.

⚠️ Warning: If the body of the Mi 5 began to "spark" at the seams or the screen began to "step away" from the frame - immediately turn off the smartphone and do not try to charge it.

What battery to choose for Xiaomi Mi 5

The original Xiaomi batteries for the Mi 5 have not been produced for a long time, but there are worthy analogues on the market. The main thing is not to run into a fake with a capacity 2 times lower than the declared one.

Best options for the ratio of price / quality (for 2026):

• 🔝 ZOP Power - capacity of 3000 mAh, 12 months warranty, thermistor included.
• 💰 PATONA P500 — 3200 mAh (slightly thicker than the original, but compatible), fast charging.
• 🛡️ BASEUS BIP-MI5 — Original size, overheating protection, 18 months warranty.

Where to buy:

• 🛒 Official stores (Mi Store, Svyaznoy, M. Video) - more expensive, but reliable.
• 🌍 AliExpress is cheaper, but choose sellers with a rating of 98%+ and photo reviews.
• 🔧 Service centers – often sell batteries in bulk at wholesale prices.

⚠️ Warning: If you see a battery for the Mi 5 with a capacity of 5000 mAh or a price below 500 rubles, this is 100% a fraud.

Required tools for replacement

To disassemble the Xiaomi Mi 5 and replace the battery, you will need:

• 🔧 Plastic blades (2-3 (a) - to remove the plumes and lids.
• 🔨 Cross screwdriver (PH00 or PH0) — hull-rotor.
• 🧲 Magnetic mat or container – so as not to lose screws.
• 🔥 Dryer or thermo-air station - to soften the glue under the battery.
• 🩹 Alcohol / isopropyl alcohol - for cleaning glue residues.
• 📦 New bilateral scotch (or glue) B-7000) — battery-lock.
• 🔋 Multimeter (optional) – to check the voltage on the new battery.

If you do not have a hair dryer, you can use a regular household, but be careful: do not overheat the case above 60-70 ° C, so as not to damage the screen or plumes. Alternatively, special heating plates for repairing smartphones (sold on AliExpress for 300-500 rubles).

Step-by-step instructions for replacing the battery

Before starting work, it is mandatory to:

1. Turn off your smartphone.
2. Extract. SIM-card and memory card (if any).
3. Discharge the battery to 20-30% (this will reduce the risk of fire if damaged).

Step 1: Removing the back cover

Xiaomi Mi 5 has a non-shattered body, so the lid is glued to remove it.

1. Heat the edge of the rear panel with a hair dryer (10-15 seconds per edge) at a distance of 5-7 cm.
2. Insert the plastic blade into the gap between the lid and the frame (start at the bottom edge where the charging connector is).
3. Carefully drive the shoulder blade around the perimeter, disconnecting the latches. Don't force it, if the lid doesn't lend itself, heat it up again.

⚠️ Careful: Fingerprint scanner plumes and antennas are running under the lid!

Step 2: Shutting off the battery

After removing the cover, you will see:

• 🔋 Battery (takes up most of the body).
• 📱 Maternity fee (at the top).
• 📶 Camera plumes and fingerprint scanner.

The first thing to do is to disconnect the battery from the charge:

1. Find the battery connector (usually black, with 3 contacts).
2. Carefully put a plastic spatula on it and unplug it. Don't use metal tools!

After the battery is turned off, the smartphone is completely de-energized, and you can continue disassembling without the risk of short circuit.

Step 3: Remove the old battery

The battery in the Mi 5 is glued to the body with double-sided tape to remove it.

1. Heat the battery with a hair dryer (50–60°C) for 1-2 minutes. This will soften the glue.
2. Put a plastic blade on the battery from any end, and slowly pull up. If it resists, heat it up again.
3. If the battery is swelling, don't puncture it! Carefully remove it without deforming.

Once removed, clean the body of glue residues with alcohol or acetone. Do not use sharp objects - you can damage the internal components.

Step 4: Installation of a new battery

Before installing the new battery:

• Check the voltage with a multimeter (should be 3.7-3.8 V).
• Make sure the connector matches the original (3 pins).
• Stick a new double-sided tape or apply a thin layer of B-7000 glue.

Put the battery back in place, plug the connector into the motherboard, and press it gently, and make sure it's flat, without any skewing.

Step 5: Build a Smartphone

Collect the Mi 5 in reverse order:

1. Connect all the plumes (fingerprint scanner, camera, speaker).
2. Install the back cover starting at the top (where the camera is).
3. So, turn all the stains (not to be worn).

After assembly, turn on the smartphone and check:

• 🔋 Battery charge (must be displayed correctly).
• 📸 Camera and fingerprint scanner operation.
• 📞 Quality of communication (antennas should not be damaged).

💡

If after replacement the battery discharges too quickly - check whether the connector is properly connected and whether the motherboard plume is damaged.

Frequent Mistakes and How to Avoid Them

Even experienced craftsmen sometimes make mistakes when replacing batteries.

• 🔌 Damage to the battery plume -- if you pull too hard on the connector, you can pull the contacts off the board. Solution: use only plastic blades.
• 🔥 Overheating of the case — if you heat the hair dryer for longer than 2 minutes, you can melt plastic latches or damage the screen. Solution: warm in short intervals (10-15 seconds).
• 📉 Incorrect calibration - after replacing the battery may show the wrong percentage of charge. Solution: completely discharge and charge the smartphone 2-3 times.
• 🧲 Loss of screws - Mi 5 uses screws of different sizes. Solution: fold them in groups on a magnetic mat.

If the smartphone does not turn on after replacement:

1. Check if the battery connector is connected.
2. Make sure the plumes are not damaged.
3. Connect to charging for 10-15 minutes – sometimes the new battery is discharged “to zero”.

Calibration of the battery after replacement

The new battery may be showing an incorrect percentage of charge. To avoid this, calibrate:

1. Completely discharge the smartphone before automatically turning off.
2. Connect to charging and wait 100% (do not turn on!).
3. Turn off the charging, turn on the smartphone and again wait for the discharge to 0%.
4. Repeat the cycle 2-3 times.

After calibration, the percentage of charge will be displayed more accurately.

• 🔄 Reset your battery settings: Go to Settings → Annexes → All applications → Three points. → Reset the settings.
• 📊 Install a monitoring application (e.g. AccuBattery) and track the actual capacity.

💡

If after calibration the battery still discharges quickly, try to turn off background activity for unnecessary applications in Settings → Battery → Optimization.

Cost of replacing the battery in the service vs independently

If you're not sure about your own abilities, you can go to a service center.

Self-replacement is more profitable, but only if you are confident in your skills. If the Mi 5 is your first smartphone to be repaired, you better practice something less valuable or consult a professional.
