Lithium-ion and lithium-polymer batteries cannot boast of durability. The condition of these batteries deteriorates with each charge, causing serious problems with the battery in the future. Therefore, it is important to know how to check the battery’s condition on the phone Xiaomi so that in case of the need to replace the battery or make use of the device more carefully.
Why do I need to know the battery condition of my smartphone?
Modern phones use lithium-polymer (Li-Pol) and lithium-ion (Li-ion ) batteries, which have several advantages. First, the environment does not affect these batteries: they can withstand temperatures from -20°C to +40°C. The smartphone won’t shut down in extreme cold or noticeably overheat in the heat.
Second, Li-Pol and Li-ion have no “memory” effect. This means there is no need to frequently calibrate and charge the phone from 0% to 100%. It is recommended to charge the device at 15-20% and unplug it when it reaches 70-80%. But even if the smartphone charges 100% and is plugged in for a few more hours – no big deal. When it reaches 100%, the power controller cuts off the current supply.
Third, lithium-polymer and lithium-ion batteries are small and lightweight, so they don’t add extra weight to the phone. They are also safe when used correctly.
But Li-Pol and Li-ion have a significant disadvantage – fast wear and tear. With each charge, the battery’s capacity decreases slightly, and after a year and a half (about 500 charging cycles ), it becomes noticeable that the smartphone begins to discharge much faster. During this period, the battery loses about 15-20% of its original capacity. If the remaining capacity is less than 80%, it is recommended to change the battery. Below we will tell you how to check the current capacity of the battery in your Xiaomi phone.

How to check the level of battery wear on Xiaomi (Redmi, POCO)
There are three basic methods to determine the battery wear level in MIUI 12. These procedures do not require you to connect to a computer and use additional equipment. Note that these methods do not guarantee 100% accuracy. There may well be errors. For a more accurate measurement, you need to use special devices unsuitable for all users.
Method 1: Using the AIDA64 app
On Google Play, there are many applications for checking the battery’s state. Unfortunately, most of these programs turn out to be useless in diagnostics. But there is still a working application – it is AIDA64. This utility is actively used to view advanced information about the device.
- Download and install the application from Google Play.
- Open the application and go to the “Battery” section.
- Here we pay attention to the items “Health” and “Discharge rate”. The “Health” line shows the approximate battery status. On my phone, it shows “Good” – which means the battery has lost no more than 5-8% of its original capacity. Also, look at the line “Discharge rate”. The normal value is no more than 200-300 mA. But before that, it is important to close all applications, remove resource-intensive background tasks, and charge the smartphone to 100%. If the discharge rate is very high, the battery is rapidly deteriorating, and soon you may need to replace it.
Method 2: creating a report
This a simple and effective method by which you can quickly diagnose the battery. On Xiaomi phones, the system app “Report”, provides advanced data on the state of the smartphone. Since the tool is already pre-installed, there is no need to download additional programs.
- Go to “Settings” – “About the phone”.
- Scroll down to “All Settings” and quickly tap the “Processor” line several times.
- A privacy policy window will pop up. Agree to save the software logs by clicking on the blue button.
- Wait a few minutes for the report to be generated. The process can be monitored in the notification curtain.
- Click on the “Report created” notification that appears. A zip-archive “bug report“ appears in the internal shared drive. To unzip it, click on it and select “Extract to current folder”.
- A folder of the same name will appear. Open it and see the same archive “bug report-camellian_global…”. Extract it to the same folder.
- There should be a new folder where the text file “bug report“ will be stored. Open the text file with any application. The most convenient application is AIReader, which can be downloaded from Google Play.
- You don’t need to look through the whole file. It is enough to enter the word “health” into the search bar. We will quickly find a line with information about the battery’s state.
- The line we need is called “battery“. Now we decode the results. Under the letter “I” the charge is displayed, but it is always different from the one shown in the status line. “t“ is the temperature, “h“ is the current state of the battery, where number 1 means “excellent” and 5 means “terrible”.
“FC“ shows the remaining battery capacity (you must look at the first 4 digits). For example, my Redmi Note 10 5G had an initial capacity of 5000 mAh, and after six months of use, it has become 4915 mAh. That is to say. There is very little wear and tear so far. The letters “cc“ show the number of charges, but this parameter is also not always correct.
Through the “Report” it is impossible to calibrate or somehow improve/influence the battery’s state. It’s just text information about your mobile device.
Method 3: enter the engineering menu
This method doesn’t work on all Xiaomi devices, so only use it if the other two methods are ineffective. Engendering Mode works correctly on Android 10. The procedure may be useless if you have Android 11 and MIUI 12.5.
- Open the Phone app and enter the combination *#*#6485#*#*.
- The “Battery and Charger Info” page will appear. First, we pay attention to the lines “MF_05” and “MF_06“. The first line indicates the battery’s current capacity, and the second is the original (declared by the manufacturer). Knowing these values, we can determine the level of wear and tear.
- The formula MF_05÷MF_06×100 also comes in handy. For example, the value of MF_05 is 4500 (the current capacity of the battery), and MF_06 is 5000 (the original capacity). So, 4500÷5000×100=90. It turns out that the current capacity is 90%: the battery has lost 10% of its original capacity.
- The line “MF_02“ shows the number of charging cycles of the smartphone. During a year, it can be about 100-200 charges.
FAQ
How do I know the original battery capacity of Xiaomi?
To do this, look at the specifications of the device. Such information is also displayed in the application AIDA64 and the engineering menu.
What to do if there is no Report app?
You most likely uninstalled this app through the Xiaomi ADB Tools utility. Try downloading the Report from a third-party source, such as the XDA Developers forum or Mi Community. You’ll have to reset your smartphone to factory settings if it doesn’t work.
Is it possible to replace the non-removable battery in the phone?
Yes. To do this, contact the service center.
How often should I change the battery?
The recommended period is once every two years, but you should also look at the percentage of wear.
We told you how to check the battery wear level on your Xiaomi. Use your device carefully and stick to the basic rules of battery operation; then, the smartphone will hold a great charge. If you still have questions, contact us in the comments.
