How to see the rest of the battery on Xiaomi: all the ways for smartphones and smart watches

Have you ever found yourself in a situation where a Xiaomi smartphone suddenly turns off at 15-20% charge? Or noticed that the battery indicator jumps like crazy? The problem is not always with a worn-out battery — often users simply do not know how to correctly check the real residue of charge. In this article, we will analyze all working methods, from standard MIUI tools to hidden engineering menus and third-party utilities.

Xiaomi devices (including Redmi, POCO and Black Shark) often optimize battery percentages for “psychological comfort.” For example, on some models, after upgrading to MIUI 14/15, the charge scale can freeze by 1% to 10 minutes, even though the phone is long dead.

1. Standard method: notification panel and settings

The most obvious, but not always accurate, method is that most Xiaomi smartphones display the battery residue:

• 📱 In the upper right corner of the screen (near the network and time icons)
• 🔋 In the Quick Settings Panel (swipe down from the top edge of the screen)
• ⚙️ Settings menu → Battery (there is also a flow schedule)

However, there are pitfalls here: On models with AMOLED-screens (e.g. Xiaomi 13 Ultra or Redmi) K60 Pro) interest can be hidden if the power saving mode is on, to get it back:

1. Go to Settings → Display
2. Select Status String
3. Activate the switch Show the percentage of battery charge

Important: On some firmware (especially the global versions of MIUI for Europe), battery percentages are disabled by default due to "design decisions." If the display settings do not have a corresponding item, use alternative methods from the following sections.

2.The battery widget on the main screen

Few people know, but MIUI has a built-in widget that shows not only interest, but also an estimate of the remaining operating time (based on current flow).

1.Push and hold your finger in the free seat of the main screen.

2. In the menu that appears, select Widgets.

3. Scroll through the list to the Tools block and find the Battery widget (the zipper icon).

4. Drag it on the screen and select the size (there are 2×1 and 4×1) options.

Add a widget to the main screen|Select a size 4×1 for detailed statistics|Check the display of working hours|Update the data with a swipe down the widget-->

This widget is useful in that it shows:

• 🔋 Exact percentage of charge (updated every 30 seconds)
• ⏱️ Remaining work/charging time (calculated dynamically)
• 📊 Flow schedule for the last 24 hours (on a large widget)

Limitation: On some models (e.g., the POCO M5), the widget may not display the running time if the performance mode is enabled, in which case the data will only be percentage.

Hidden Engineering Menus: Codes for Accurate Diagnostics

If you want the most accurate data on battery status, including voltage, temperature and charging cycles, use engineering codes. These menus are hidden from ordinary users, but contain detailed technical information.

The most useful teams:

• 📞 ##4636## - Basic test menu (Battery Information section)
• 🔧 ##6484## - Battery test (indicates the actual charge level in mV)
• 🔍 ##64663## - Advanced diagnostics (includes data on charging cycles)

Once you enter the code, you will be taken to the menu where you can select Battery information (or similar in Chinese if you have firmware for the Chinese market).

• Level: Real percentage of charge (may differ from what the system shows)
• Voltage – current voltage in millivolts (normal: 3700-4200 mV)
• Temperature – battery temperature (optimum: 25–40°C)
• Health – battery status (if any)

Warning: Do not change the parameters in the engineering menus if you do not understand their purpose! For example, resetting the charging cycle counter (Battery reset) can lead to improper operation of the power management system.

4 Third-party applications: AccuBattery and Battery Guru

If the built-in MIUI tools don't suit you, look for specialized utilities that not only show the exact residue of charge, but also analyze battery health, discharge rate and optimal charging cycles.

Top.-3 apps:

Tip: Once you install AccuBattery, complete the full discharge/charging cycle (0 to 100%) so that the application calibrates the data, which will take about 4-6 hours, but then the figures will be as accurate as possible.

💡

If after installing the application for monitoring the battery, the smartphone began to discharge faster, check the background activity settings: go to Settings → Applications → Application Management, find the utility and turn off auto-start for it.

5. Checking the battery balance on smart watches and fitness bracelets Xiaomi

Mi Band, Xiaomi Watch and Redmi Watch devices also show battery power, but the ways are different from smartphones.

For Mi Band 7/8 and Xiaomi Smart Band Pro:

• 📱 On the main screen of the bracelet, swipe up - the percentage of charge will appear.
• 🔋 In the Mi Fitness (or Zepp Life) app, open the Device tab. → Battery status.
• ⚡ If the bracelet is discharged to 0%, connect it to charging - interest will appear in 5-10 minutes.

For Xiaomi Watch S3 and Redmi Watch 3 Active:

• 🕒 Click on the top button to open the menu and select the battery icon.
• 📊 In the Xiaomi Wear app, go to the Device Profile → Battery.
• 🔌 When the charge is low (less than 10%), the watch automatically goes into saving mode.

⚠️ Note: On the Mi Band older than version 5 (2020 and earlier), the charge percentages are only displayed in the app, not on the bracelet screen. If you can't see the data, update the firmware via Mi Fitness.

6. Battery wear check: how to find out the real capacity

The remaining charge is good, but it's more important to understand how worn the battery is, because over time, the battery capacity decreases, and 100 percent is not even the factory value.

Method 1. via AccuBattery (without Root):

1. Charge your smartphone to 100% and disconnect from the network.
2. Use your phone as normal until it is discharged to 0% (before it automatically shuts down).
3. Connect the charger and wait for the switch on.
4. Open AccuBattery and go to the Health tab – there will be an indicator of Estimated capacity.

Method 2. Through the engineering menu (requires Root or ADB):

adb shell dumpsys battery

In the commands output, look for the lines:

• level - current charge in percentage
• voltage
• Capacity – current maximum capacity (compare with factory capacity)

⚠️ Note: If the actual battery capacity has fallen below 70% of the factory capacity (for example, instead of 5000 mAh, 3,500 mAh remains), the battery needs to be replaced.

💡

The battery wear rate is up to 20 percent per year, and if capacity drops faster, check to see if you're using your smartphone at extreme temperatures (below 0°C or above 45°C) and charging it with "cheap" cables without certification.

7. Frequent problems and their solutions

Sometimes the system shows incorrect data about the battery, and here are the situations and ways to fix them:

Problem 1: Charge percentages get stuck (for example, 1% or 100% hangs for a long time).

• 🔄 Reboot your smartphone – it will reset the cache of the power management system.
• 🔧 Calibrate the battery: discharge the phone before turning off, then charge to 100% without interruption.
• 📱 Update the firmware - in older versions MIUI There were charge-displaying bugs.

Problem 2: The phone turns off at 15-30% charge.

• 🔋 Check battery wear (see section 6). If the capacity is below 60%, replace the battery.
• 🔌 Use the original charger – uncertified RAMs can knock calibration.
• 📉 Turn off battery optimization for critical applications in Settings → Battery → Optimizing the battery.

Problem 3: The lock screen does not display interest.

• ⚙️ Go to Settings. → Lock screen.
• 🔍 Find the lock screen style and select the option with the charge display.
• 🎨 If you use third-party themes, go back to the standard one – some topics hide percentages.

If none of these methods worked, the power controller may have failed, in which case, contact Xiaomi’s service center (addresses can be found on mi.com/service).
