Redmi Note 10 Pro remains one of the most popular smartphones Xiaomi due to the balance of price and characteristics, but over time even a reliable battery 5020 mAh begins to lose capacity. If your device discharges in a few hours, turns off at 20-30% charge, or overheats while charging, it's time to think about replacing the battery.
In this article you will find step by step instructions with photos of key stages, comparison of original and analog batteries, as well as tips on how to extend the life of a new battery. We'll look at what tools you'll need, how much it costs to replace it at a service center versus doing it yourself, and what to do if your phone doesn't turn on after replacement. Let us dwell separately on typical errors that lead to damage to the display cable or motherboard - this information is not in 90% of manuals!
Signs that the battery is Redmi Note 10 Pro needs replacement
Lithium polymer batteries degrade even when used carefully. Here 5 Key Symptoms, which signal the need for replacement:
- 🔋 Sudden shutdowns at a charge level of 20-40% (especially in cold weather). This is due to the loss of real capacity and incorrect operation of the controller.
- ⚡ Fast discharge — the phone loses 50% of its charge in 1-2 hours with minimal load (for example, in standby mode).
- 🔥 Overheating while charging or playing (body temperature is above 45°C). This is dangerous not only for the battery, but also for the processor Snapdragon 732G.
- 📉 Bloating of the body — if the back cover begins to “come off” or the screen rises, this is critical signal: The battery needs to be replaced immediately!
- ⏳ Long charging - from 0 to 100% more than 3-4 hours when using the original 33 W charger.
For diagnostics you can use applications like AccuBattery (shows actual capacity) or built-in menu *#*#4636#*#* (section "Battery information"). If the value health below 70%, the battery must be replaced.
⚠️ Attention: If the battery is swollen, do not try to pierce or squeeze it - this may cause a fire! Take the phone to a service center or disassemble it in a well-ventilated area, avoiding contact with metal objects.
Which battery to choose: original vs analogues
There are three types of batteries on the market for Redmi Note 10 Pro (model M2101K6G):

Preparing for replacement: tools and safety precautions
To replace it yourself you will need:
T3 (Torx) screwdriver for back cover screws
Plastic paddles or picks (2-3 pcs.)
Suction cup for removing screen (diameter 5-7 cm)
Hair dryer or hot air station (to soften the glue)
Tweezers with fine tips
Multimeter (to check battery voltage)
Alcohol wipes (for cleaning contacts)
New battery with adhesive base-->
Important: work on a clean, illuminated surface no carpets (static electricity can damage the motherboard). Turn off your phone and remove the SIM card and memory card before disassembling.
If you have never disassembled smartphones, practice on an old device or watch video guides. For example, channel Fixez on YouTube shows the process in detail for Redmi Note 10 Pro:

⚠️ Attention: If you use a hair dryer to heat the glue, Do not direct hot air at the screen or battery - this may damage the OLED matrix or cause electrolyte leakage. Optimal temperature: 60-70°C, distance - 10-15 cm.
Step-by-step instructions for replacing the battery
The whole process will take 30-60 minutes depending on experience. Follow the instructions strictly in order:
- Removing the back cover:
Heat the edges of the case with a hairdryer (especially around the power and volume buttons) for 2-3 minutes. Using a plastic spatula, carefully pry up the gap between the cover and the frame. Start from the bottom left corner - the glue is weaker there. Be careful: under the cover they pass fingerprint scanner and NFC antenna cables!
- Battery disconnection:
Remove the 4 screws securing the metal plate above the battery. Disconnect the battery connector with tweezers (it is located at the top of the board). Don't pull the wires! - only for the black plastic connector.
- Removing the old battery:
Use a plastic spatula to pry the battery out of the side (where there are no cables). If it gets stuck, gently pull the special black tape (pull-tab). If there is no tape, use isopropyl alcohol to dissolve the glue. Do not use metal tools - risk of short circuit!
- Installing a new battery:
Remove the protective film from the adhesive base of the new battery and carefully press it to the case. Connect the connector to the motherboard (it should “click” with a slight click). Make sure the cable is not twisted or stretched.
- Phone assembly:
Check that all connectors are connected (especially the fingerprint scanner!). Tighten the screws crosswise to avoid distortion. Press the back cover and heat it with a hairdryer to activate the glue.
After assembly don't turn on your phone right away - let the glue dry for 10-15 minutes. Then connect the charger and monitor the charging process: if the battery heats up above 40°C or the phone does not recognize charging, immediately disconnect it and check the connector connection.
1) The battery connector is connected correctly (it must fit tightly).
2) The integrity of the display cable (sometimes it comes off when the cover is removed).
3) There is a short circuit (measure the voltage at the battery contacts with a multimeter - it should be 3.7–4.2 V).-->
What should I do if problems arise after replacement?
Even with careful replacement, problems may occur. Let's look at typical scenarios and solutions:
| Problem | Possible reason | Solution |
|---|---|---|
| The phone won't turn on | Unconnected battery connector or display cable | Disassemble the phone and check all connections. If it doesn't help, test the battery with a multimeter. |
| New battery drains quickly | Poor quality analogue or calibration failure | Perform a full discharge/charge cycle (0-100%) 2-3 times. If it doesn't help, replace the battery. |
| Overheating while charging | Damaged charging controller or poor quality battery | Try a different charger. If the heating persists, contact service. |
| Incorrect display of charge level | System failure after replacement | Reset settings via Settings → System → Reset settings (without deleting data). |
If your phone turns on but the battery drains within a few hours, check background processes in the menu Settings → Battery. Sometimes unoptimized applications are to blame (for example, Facebook or TikTok), and not the battery itself.
If after replacement the phone displays the error “Not original battery”, do not panic - this is normal for analogues. Functionality will not be affected, but the accuracy of the charge indicator may be slightly reduced.

How to extend the life of a new battery?
Even the original battery will last longer if you follow these rules:
- 🔌 Charging: Use original memory Xiaomi at 33 W. Avoid "turbo" chargers from other brands - they can overheat the controller.
- 🌡️ Temperature: Do not leave your phone in the sun or near heaters. Optimal range: 10–35°C.
- 🔋 Charge level: Try to keep the battery between 20-80%. Full discharge (0%) and overcharge (100%) will shorten the service life.
- 📵 Storage: If you do not use your phone for a long time, charge it to 50% and turn it off. Store in a cool place.
- 🎮 Games and heavy applicationsNote: When gaming for long periods of time, remove the case for better cooling.
Modern lithium polymer batteries are designed to 300–500 charging cycles. If used carefully, a new battery will last for 2-3 years. If you notice that the capacity starts to drop again (for example, after 18 months), repeat the replacement procedure - it's cheaper than buying a new phone!
Enable Adaptive Charging in Settings (Settings → Battery → Advanced). It limits the charge to 80% at night, reducing battery wear.
