Today’s Xiaomi smartphone users rarely think about the internal architecture of their device until they are faced with the need to install specific software or deep customization of the system. The question of how to know how many bits on a Xiaomi phone becomes relevant when it comes to app compatibility or performance in demanding games. CPU bitwise is a fundamental characteristic that determines how a device processes data.
Most of the current models released in the last 5-6 years have long since moved to the standard 64-bit architecture, which allows you to use more than 4 GB of RAM. However, there are still budget models or older devices running on the basis of 32-bit cores. Understanding this difference is critical for those who are planning to install custom firmware or optimize the system.
In this article, we’ll look at all the ways you can determine your gadget’s bit size, from simple methods through the settings menu to advanced options using debugging commands. You’ll learn to distinguish between specifications and understand what’s hidden under your Redmi or Poco’s hood.
Why it is important to know the digitization of the smartphone architecture
The bitwiseness of the processor directly affects how much memory a device can address. Simply put, a 32-bit system cannot physically work correctly with a memory capacity exceeding 4 GB. Owners of Xiaomi smartphones with 6 or 8 GB of RAM, but a 32-bit processor, do not actually use the full potential of iron.
App developers are increasingly refusing to support 32-bit versions of their programs. Google Play has been requiring all new apps and updates to have a 64-bit version for several years, which means that on older devices, some modern services may simply not start or run unstable.
⚠️ Warning: Installing 64-bit firmware on a 32-bit device (or vice versa) will cause the phone to fail completely (brick.
For gamers, this parameter also matters. Modern engines like Unreal Engine 4 or 5 may require certain instruction sets that are only available in 64-bit mode. Knowing the exact specification helps avoid frustration when buying games or trying to emulate console projects.
Check the bit rate through the menu “About the phone” and settings
The easiest and safest way to get the primary information is to look at the system menu. Although it rarely spells out "64 bits," indirect features can give an accurate answer. Go to Settings → About Phone → All settings.
Note the line “RAM.” If your Xiaomi phone has 4GB of RAM or less, the likelihood of it being a 32-bit device is high, especially if the model is budget (Redmi A series or older Redmi Go). Devices with 6, 8 or more GB of memory are almost guaranteed to be 64-bit.
Also worth looking at is the Android version. Starting with Android 5.0 Lollipop, support for 64-bit processors became the standard, but the full transition came later. If you have Android 10 or newer and the processor is not overtly old (like the Snapdragon 4xx series), then the system is likely 64-bit.
Use of specialized applications for diagnostics
The most reliable method that doesn't require a computer connection is to install profile software. There are many tools available in the Google Play or GetApps store that read information directly from the kernel, and one of the most popular and informative is CPU-Z.
Once you install and run the app, go to the System or Device tab, find the Kernel Architecture field, or just Architecture field, and it will show a value like armv8 or aarch64, which clearly indicates a 64-bit architecture, and if you see armv7 or armeabi, you're looking at a 32-bit device.
💡
The CPU-Z app will also show the current processor frequency and core temperature in real time, which is useful for overheating diagnosis.
Other useful applications that provide similar information:
- 📱 AIDA64 — Provides a detailed report on all components, including the processor instruction sets.
- 🔧 DevCheck Device & System Info - user-friendly interface and the ability to export data to a text file.
- 📊 AnTuTu Benchmark – The device information section also specifies the type of architecture CPU.
These tools run on all versions of the MIUI shell and the new HyperOS, which are root-free and safe for use on warranty devices, and are updated in real time to track core loads.
Definition of bits through a computer and ADB-team
For advanced users with access to a PC, there is a method of checking through the ADB debugging bridge (Android Debug Bridge), which provides the most accurate technical data, since it queries it directly from the Linux kernel on which Android is based. First, you need to include USB debugging in the Settings → About menu (7 times click on the build number) and activate the item in the Developer menu.
Connect your phone to your computer with a cable and open the command line or terminal in the ADB tool folder. Enter the following command to check the supported instructions:
adb shell getprop ro.product.cpu.abiIf you get arm64-v8a, your CPU is 64-bit, the answer to armeabi-v7a is 32-bit architecture, and you can use the adb shell cat /proc/cpuinfo command, which will display a detailed list of the characteristics of all the CPU cores.
☑️ Preparation for verification through ADB
This method is especially useful if the phone screen is broken but the touchscreen is partially working, or if the system is loading unstable. ADB You can access critical settings even in Recovery mode (if there is support for it). ADB).
Analysis of the characteristics of the processor by device model
If you can't run tests, you can look at the specifications of the processor model. Xiaomi smartphones most often use chips from Qualcomm Snapdragon, MediaTek Helio/Dimensity or Samsung Exynos. Knowing the model of the processor, you can tell exactly how many bits it supports.
Below is a table of correspondence of popular series of processors and their bit size:
| Processor series | Examples of models | Bit-of-bit | Year of the year |
|---|---|---|---|
| Qualcomm Snapdragon 4xx | 410, 425, 430 | 32/64 bits* | 2014-2016 |
| Qualcomm Snapdragon 6xx/7xx/8xx | 660, 730, 865, 8 Gen 2 | 64 bits | 2015-present |
| MediaTek Helio P/G | P10, G80, G99 | 64 bits | 2015-present |
| MediaTek Dimensity | 900, 1200, 9200+ | 64 bits | 2020-now. |
*Note: Early versions of the Snapdragon 410 could have been 32-bit, but subsequent revisions and newer 4xx series models have already moved to 64-bit. The Snapdragon 8xxx series processors are always flagship and exclusively 64-bit.
You can find out the exact model of the processor in the same menu "About the phone" or through the diagnostic applications. Searching the Internet for the name of the chip (for example, "Snapdragon 625 specs") instantly reveals its architecture, this is especially true when buying a used device when you can not turn on the screen.

⚠️ Note: When installing applications from unknown sources (APK-Files: Always pay attention to the version: arm64-v8a It is designed for modern 64-bit phones, and armeabi-v7a — for older 32-bit models.
Understanding the bitiness of your Xiaomi device is an important step in smart smartphone use, which helps you avoid errors when installing software, properly assess the potential of the device for gaming, and understand the limitations of the system. Whether you use a simple Redmi or a flagship Mi, the architecture of the processor remains a key factor in its performance.
