The battery is one of the most vulnerable components of a smartphone, and the Xiaomi Redmi Note 10 Pro is no exception. Over time, battery capacity decreases, leading to rapid discharge, sudden blackouts and charging problems. But how do you know exactly what condition your device's battery is in? There are several methods, from built-in MIUI tools to third-party applications and engineering codes.
Many users mistakenly believe that if the phone is less charged than before, it is time to change the battery, but the true state of the battery is determined not only by battery life, but also by parameters such as charging cycles, current capacity and degradation rate. In this article, we will examine all available diagnostic methods, from simple to professional.
It’s important to understand that the Redmi Note 10 Pro features a 5020 mAh lithium polymer battery that Xiaomi specs should retain at least 80% of its capacity after 500 full charge cycles, but the real numbers depend on the operating conditions: temperature, fast charging, and even the habit of leaving the phone on charge overnight.
1. Check through the built-in MIUI menu
The easiest way to assess the battery status is to use standard MIUI firmware tools, which do not require additional software or engineering codes.
Go to Settings → Battery and Performance → Battery status. Here you will see two key parameters:
- 🔋 Wear level - percent of capacity loss relative to factory value.
- 📊 Status assessment – general assessment (e.g., “Good”, “Mediocre” or “Bad").
If the wear level is greater than 20-25%, it is a signal that the battery is approaching a critical state, but it is worth considering that MIUI sometimes underestimates the real figures, so it is better to use alternative methods for accurate diagnosis.
💡
If the Battery Status menu displays a message that says “Impossible to determine,” try restarting your phone or updating your firmware to the latest version.
2. Engineering menu: hidden battery data
For more information, you can use the Xiaomi Engineering Menu, which is suitable for advanced users, as it requires you to enter special code.
Open the phone application and enter the combination:
##4636##In the menu that opens, select Battery Information. Here you will find the following data:
- 📏 Charge level – current percentage in real time.
- ⚡ Voltage - should be in the range of 3.7-4.4 V when fully charged.
- 🔥 Temperature - optimal range of 20-40°C. Exceeding 45°C critically!
- 🔄 Technology – should be displayed as Li-polymer.
What to do if the engineering menu is not opened?
Critical warning: If the battery voltage is below 3.4V or the temperature is above 50°C, immediately disconnect the phone from charging and do not use it until the battery is replaced!
3. Diagnostic applications: AccuBattery and AIDA64
The utility side allows you to get more accurate data than the built-in tools. Let's look at two of the most popular applications.
AccuBattery (free, premium) analyzes the charging cycles and assesses the actual battery capacity.
- Charge your phone to 100% and disconnect from the network.
- Use your smartphone until it is completely discharged (until it is automatically turned off).
- Connect the charger and wait 100%.
- Check the Health tab - the current capacity in mAh will be displayed here.
AIDA64 (paid but trial) provides detailed technical information. After launch, go to the Battery section, where you will see:
- 📋 Status (e.g., "charged" or "discharged").
- 🔋 Charge level in percentages and milliamperes.
- 🌡️ Temperature in degrees Celsius.
- 🔄 Technology and tension.
Note that the first 2-3 charge/discharge cycles in AccuBattery may not show accurate data. Use the app for at least a week to evaluate objectively.
4. Test through ADB: for advanced users
If you want the most accurate data, you can use Android Debug Bridge (ADB), which requires connecting your phone to your computer and basic command line knowledge.
First, turn on the Developer Mode:
- Go to Settings. → The phone.
- Press 7 times on the MIUI version.
- Back to Settings → Additionally. → For developers.
- Activate Debugging on USB.
Next, connect the Redmi Note 10 Pro to your PC, open the command prompt (or Terminal on Mac/Linux) and type:
adb shell dumpsys batteryIn the conclusion, find the lines:
- Level is the current charge in percentage.
- Voltage is the voltage in microvolts (divided by 1000 for volts).
- Temperature - temperature in tenths of a degree (divided by 10).
- Health – state (GOOD, OVERHEAT, DEAD, etc.).
Install ADB-PC drivers|
Enable debugging over USB on your phone |
Connect the phone with the original cable |
Start the command line on behalf of the administrator-->
If the health field indicates OVERHEAT or COLD, this means that the battery is operating in extreme temperature conditions, which accelerates its degradation, in which case it is recommended to let the phone cool (or warm up) to room temperature before further use.
5. Visual Diagnostics: When the Battery Needs to Be Changed Urgently
Sometimes you can evaluate the battery without software, by external signs.
- 🔺 Bloating – if the back cover or screen has started to “go away”, this is a sure sign of a faulty battery.
- 🔥 Overheating – if the phone heats up even with minimal load (e.g., in standby mode).
- ⚡ Spontaneous shutdowns – if the phone turns off at 20–30% charge.
- 🔌 Charging problems – slow charging or stopping by 80-90%.
⚠️ Warning: If the battery is swelling, don't try to puncture or bend it! Lithium polymer batteries can ignite if damaged.
To check for battery bloating, put your phone on a flat surface and push it slightly on the back cover, and if it bends or creaks, it's a sign of deformity, and also pay attention to the screen: if it's raised around the edges, it's likely that the battery has expanded.
Comparison with factory performance: degradation table
To see how worn the battery is, compare the current numbers to factory ones. Below is the degradation table for the Redmi Note 10 Pro (5020 mAh):
| Level of wear and tear | Current capacity (mAh) | Autonomy | Recommendations |
|---|---|---|---|
| 0–10% | 4500–5020 | Full day of active use | Perfect condition, no action required |
| 10–20% | 4000–4500 | Decrease in autonomy by 10-15% | Watch the temperatures, avoid fast charging |
| 20–30% | 3500–4000 | The charge is kept 30-40% less | Consider replacing the battery soon. |
| 30–40% | 3000–3500 | The phone discharges in 4-5 hours | Replacement is required, further degradation will accelerate |
| 40%+ | Less than 3,000 | Spontaneous shutdowns, overheating | Exploitation is dangerous! Immediate replacement |
If your performance falls within the 30 percent+ wear zone, it means that the battery will last no more than 6 to 12 months, even when used carefully, in which case it is advisable to schedule a replacement in advance to avoid sudden breakdowns.
💡
Capacity below 3500 mAh on the Redmi Note 10 Pro is considered critical - autonomy is reduced by 1.5-2 times, and the risk of bloating increases.
7.How to prolong the life of the battery: 5 practical tips
Even if the battery is still in good condition, following a few rules will help slow down its degradation:
- 🔌 Avoid full discharges - optimal charge range of 20-80%. Regular discharges to 0% reduce the life of the battery.
- ⚡ Don’t use fast charging all the time – Redmi Note 10 Pro supports 33W, But frequent fast charging heats up the battery.
- 🌡️ Control the temperature – do not leave your phone in direct sunlight or near heat sources.
- 📵 Disable unnecessary functions — GPS, NFC and background applications increase the load.
- 🔄 Update the firmware - in new versions MIUI Optimized energy consumption.
⚠️ Note: If you use wireless charging, consider that it heats the battery more than wired. For the Redmi Note 10 Pro (which doesn't officially support Qi), this is especially risky - only use certified adapters.
Another useful life hack: if you don't plan to use your phone for a few days (like on a trip), charge it up to 50% and turn it off. Storage with full or zero charge accelerates degradation.
