Xiaomi Redmi Note 10 is one of the most popular mid-range smartphones, but even its reliable 5,000mAh battery loses capacity over time. If the phone starts to run out in a few hours, overheat when charging or turn off by 20-30%, it’s time to diagnose the battery. In this article, 5 proven ways to assess the state of the battery without disassembling the device, including hidden engineering menus, third-party apps and data analysis from MIUI.
We’ll not only look at how to find the current capacity, but also how to interpret the results: what are the normal values for the Redmi Note 10 after 1-2 years of operation, and when to think about replacing it, and you’ll find a table matching the percentage of wear and tear to real-time operation and tips on how to minimize battery degradation.
1. Check through the engineering menu (code ##4636##)
The fastest way to get data about the battery is to use a hidden engineering menu, which is available on all Xiaomi Android smartphones, including the Redmi Note 10. Importantly, this method shows the current state, but not the wear history.
Instructions:
- 📱 Open the phone app and enter the combination: ##4636##.
- 🔧 In the menu that appears, select Battery Information).
- 📊 Note the lines: Level of charge (Level) – current percentage; Status – should be Charging or Discharging; Health (Health) – if any, shows wear in percentage (some firmware is missing).
⚠️ Warning: If there is no Health item on the menu, it does not mean that the battery is in good condition. MIUI 12-14 This option is often hidden – use alternative methods in the following sections.
💡
If the engineering menu does not open, check if it is blocked by antivirus or the Fraud Protection feature in the MIUI security settings.
2. Use of a secret code for diagnosis (##6484##)
For the Redmi Note 10, there is a special service code that displays advanced information about the battery, including the number of charging cycles and current capacity, a method more accurate than the standard engineering menu.
How to check:
- Open the Phone app and type in ##6484##.
- In the MTK Engineer Mode window that appears, go to the Battery tab.
- Pay attention to the parameters: 🔋 Battery capacity - current capacity in mAh (compare with passport 5000 mAh); 🔄 Charge cycles – number of full charging cycles (normal up to 500); 🌡️ Temperature: Battery temperature (optimally 25–40)°C).
📌 Example of depreciation calculation: If the current capacity shows 4200 mAh, wear is a bit of a drag (5000 - 4200) / 5000 × 100% = 16%. This means that the battery has lost 16% from the original container.
3. Diagnostic applications: AccuBattery and AIDA64
Third-party utilities allow you to track the state of the battery in dynamics, recording changes in capacity and discharging speed. For the Redmi Note 10, we recommend two applications:
1. AccuBattery (free version with limitations):
- 📊 Shows the actual battery capacity after 2-3 charging cycles;
- 🔋 Estimates battery health as a percentage;
- ⚡ Tracks the speed of charging and discharging;
- 📉 Builds degradation graphs.
2. AIDA64 (paid but with trial period):
- 🔍 Detailed information about battery model, manufacturer and production date;
- 📡 Shows voltage and temperature in real time;
- 📋 Save logs for analysis.
⚠️ Note: Apps may show inaccurate data in the first days of use. For correct results, run 2-3 full charge/discharge cycles (0% to 100%).
☑️ Preparation for the test in AccuBattery
4.Analysing data through MIUI Battery Care
Starting with MIUI 12.5, Xiaomi’s firmware has a built-in Battery Care feature that automatically limits the charge to 80-90% for extended life, but it also stores wear data.
How to find information:
- Go to Settings → Battery and Performance → Battery Care →
- Activate the mode (if not enabled).
- Click on the icon. ⚙️ (Settings) in upper right corner.
- Select Battery Status – This shows the percentage of wear and tear (if supported by your version of MIUI).
🔍 What do you do if you don't have a paragraph? MIUI (For example, for global firmware, this partition may not be available. ADB-Teams (see next section).
| Percentage of wear and tear | Battery status | Recommendations |
|---|---|---|
| 0–10% | Excellent. | The battery is almost new, degradation is minimal. |
| 10–25% | Good. | A slight reduction in operating time. Watch the temperatures. |
| 25–40% | Satisfactory | The phone discharges 20 to 30 percent faster. Consider replacing it in 6 to 12 months. |
| 40–60% | Bad. | Capacity is critically low. Battery is swelling, phone is overheating. |
| 60%+ | Emergency. | We need an urgent replacement, the risk of a sudden shutdown and damage to the board. |
5. Verification through ADB (for power users)
If standard methods do not show wear, you can get data through Android Debug Bridge (ADB), which requires a connection to a computer, but gives the most accurate information.
Instructions:
- Download and install ADB Tools on PC.
- On your phone, activate Developer Mode: Go to Settings → About Phone; Click 7 times on MIUI Version; Return to Settings → Additional → For Developers and enable USB Debugging.
Redmi Note 10
adb shell dumpsys battery- Capacity is the current capacity.
- charge counter - the amount of charge in mkAh (divided by 1000 for mAh);
- Health is the state (2 = good, 3 = bad).
💡 Example of conclusion: If the charge counter = 4.5 million, real capacity - 4500 mAh (wear 10%).
What if the ADB does not recognize the device?
6. Visual diagnosis: signs of battery wear
Even without special tools, you can suspect problems with the battery on indirect grounds.
- 🔥 Overheating during charging or playing (temperature above 45)°C);
- 📉 Sudden shutdowns at 20–30% charge;
- 🐢 Slow charging (longer than 3 hours from 0% to 100%);
- 📱 Bloating (check if the phone is on the table);
- ⚡ Percentage charge jumps (e.g., from 50% to 20% per second).
⚠️ Attention: If the case of the Redmi Note 10 is swelling, you can not continue to use the phone! a bloated battery can damage the screen or motherboard, and in rare cases, ignite.
💡
If the phone is turned off at 30-40% of the charge, this is a sure sign that the actual battery capacity has fallen below 60% of the nominal.
