In the modern world of mobile technology, processor capacity plays a key role in device performance. Users often ask the question how to check how many bits are on Androidto understand the capabilities of their gadget. This knowledge is necessary not only for enthusiasts, but also for ordinary smartphone owners who want to install specific software or optimize the system.
The architecture capacity determines how much RAM the processor can address and how efficiently it processes data. If your device runs on a 32-bit architecture, it will physically not be able to run applications compiled exclusively for 64-bit systems. Conversely, a 64-bit processor is capable of executing code from both architectures, while providing faster computational speeds and support for larger volumes RAM.
There are several reliable ways to determine this characteristic without the need to disassemble the phone or have in-depth programming knowledge. We will consider methods from the simplest, accessible to any user, to advanced methods via a computer. You will be able to find out exactly what architecture CPU is installed in your smartphone, be it an old budget phone or a modern flagship.
Why you need to know the bit depth of your smartphone's processor
Understanding the architecture of your device helps to avoid many problems with software compatibility. Many modern games and heavy applications require a 64-bit system to work correctly. If you try to install such a app on a 32-bit device, the installation will either not start, or the application will constantly crash immediately after launch.
In addition, knowing the bit depth is important when choosing custom firmware or restoring the system after a failure. Developers of unofficial builds Android always indicate the target architecture in the description of their product. Installing the wrong version can turn your phone into a “brick”, requiring complex recovery via the mode Fastboot.
⚠️ Attention: Never flash images designed for a different processor architecture. This may lead to irreversible damage to the bootloader and loss of warranty on the device.
This information is also useful when purchasing used equipment. Unscrupulous sellers may pass off old models as new, hiding the fact that an outdated 32-bit chipset is installed inside. Checking the bit depth allows you to instantly verify the real characteristics of the gadget before the transaction.
Use specialized applications for diagnostics
The easiest and safest way to find out the processor architecture is to use third-party utilities from the store Google Play. These applications collect comprehensive information about the hardware and display it in a user-friendly form. You do not need to be a system administrator to understand the received data.
One of the most popular tools is the application CPU-Z. After installation and launch, go to the System or SoCtab. The Kernel Architecture or Instruction Sets field will indicate support for command sets. If you see the mention arm64-v8a, then your processor is 64-bit. The presence of only armeabi-v7a indicates a 32-bit architecture.
It is considered to be AIDA64another powerful tool. This application provides detailed information not only about the processor, but also about the sensors, battery and display. In the section CPU pay attention to the line Instruction Set. It will clearly state which instructions the kernel supports. The presence of a suffix 64 in the name of the instruction set confirms the appropriate bit depth.
Check permissions before installing diagnostic applications. Good utilities do not need access to your contacts or microphone to analyze hardware.
Another reliable option is the application DevCheck Device & System Info. It features a modern interface and the ability to monitor frequencies in real time. In the processor information section, it also clearly indicates the bit depth of the current operating environment and the maximum supported bit depth of the chip.
Checking through developer settings and_about phone_
In some cases, the built-in system tools can prompt the necessary information, although manufacturers often hide technical details from the eyes of the average user. However, it is worth checking the standard settings menu before downloading additional software.
Go to the section Settings and find the item About phone (About Phone). Sometimes the subsection Processor or Characteristics indicates the chip model. Knowing the exact model, for example Snapdragon 625 or MediaTek Helio P60, you can quickly find its specification in a search engine and find out the bit depth.
A more advanced method involves enabling developer mode. To do this, you need to quickly click on the build number in the menu About phone7 times. After the message “You have become a developer” appears, return to the main settings menu and open a new item For developers.
- 🔍 Enable USB debugging if you plan to connect the phone to a PC.
- 📊 Find the "Running services" item (Running services) - sometimes the process architecture is visible there.
- ⚙️ Check the "Bug report" section - the reports often contain a complete technical summary.
However, it is worth remembering that the standard menu does not always show the direct bit value. Most often, it serves as a starting point for obtaining the processor model, which then needs to be entered in the database.
Where can I find the build number?
Usually it is located at the very bottom of the “About phone” menu. On some shells, such as MIUI or OneUI, the path may be different: Settings -> About phone -> MIUI/OneUI version.
File system analysis without root access
For those who do not want to install unnecessary applications, there is a method of checking through a file manager. Modern file managers, such as FX File Explorer or Root Explorer (without root access it is also partially functional), allow you to view system directories available for reading.
You need to go to the root of the file system and open the folder /system/lib. Look at the contents of this directory. If you see libraries with names containing arm64, or if the folder itself contains subfolders for 64-bit libraries, this is a sure sign of the corresponding architecture.
An alternative way is to check the folder /proc. In some file managers, you can open a file cpuinfolocated along the path /proc/cpuinfo. This text file contains raw processor data. Look for lines Features or model name. The presence of flags lm (long mode) or mention aarch64 confirms 64-bit.
⚠️ Attention: Be careful when navigating through system folders. Accidentally deleting or changing files in a directory
/systemcan lead to unstable operation of the operating system.
This method requires care, since the information is presented in a technical format. However, it does not require the installation of additional software and works even on devices with a locked bootloader.
Using the ADB computer utility
The most accurate and professional way to check is to use a debug bridge Android Debug Bridge (ADB) via a computer. This method gives direct access to the system properties of the device and eliminates any distortion of information from the user interface.
First, you need to install the drivers for your smartphone and the platform SDK Platform Tools on your computer. Connect your phone to the PC with a cable, having first enabled USB debugging in the developer menu. Open a command line or terminal in the folder with the utility adb.
Enter the following command to check the processor properties:
adb shell getprop ro.product.cpu.abiThe system will return a value that will uniquely indicate the architecture. If the answer is arm64-v8a, then you have a 64-bit processor. If you see armeabi-v7a, then the device runs on a 32-bit architecture. For more detailed information, you can use the command:
adb shell cat /proc/cpuinfoThis method is especially useful if the phone screen is broken or the sensor does not work, but the device turns on and is detected by the computer. You can get all the necessary information remotely.
☑️ Preparing to work with ADB
Comparison of architectures and impact on performance
The difference between 32 and 64 bits is not only in support memory, but also in computing efficiency. 64-bit processors can process more data per clock cycle, which is critical for modern tasks such as photo processing, video editing and complex 3D games.
Below is a table demonstrating the key differences between the two architectures in the context of mobile devices:
| Characteristics | 32-bit (ARMv7) | 64-bit (ARMv8/AArch64) |
|---|---|---|
| Maximum RAM | up to 4 GB (actually ~3.2 GB) | Theoretically up to 16 Exabytes |
| Performance | Basic, sufficient for simple tasks | High, optimized for heavy loads |
| Energy efficiency | Lower at high loads | Higher thanks to improved architecture |
| Software compatibility | Only 32-bit applications | Support for 32 and 64-bit applications |
Modern ecosystem Android is gradually abandoning support for 32-bit applications. Starting with certain versions of the operating system, the presence of a 64-bit processor becomes a mandatory requirement for certification of new devices. This means that buying a new 32-bit smartphone today is an investment in a device with a limited lifespan.
The transition to 64-bit architecture is inevitable: new versions of Android and applications gradually stop supporting 32-bit systems.
Frequently asked questions about Android bit depth
You can Is it possible to upgrade a 32-bit phone to a 64-bit system?
No, this is not possible. The bit capacity is determined by the physical characteristics of the processor (crystal). No software update can change the hardware architecture of the chip. If the processor is 32-bit, it will remain so forever.
Will 32-bit applications run on 64-bit Android?
Yes, in most cases, 64-bit processors support the execution of 32-bit code through compatibility mode. However, some manufacturers may remove 32-bit libraries from their firmware to save space, which will lead to old applications not working.
Does bit depth affect charging speed?
Indirectly yes. 64-bit processors are usually more energy efficient when performing complex tasks, which can reduce overall heat dissipation and power consumption, but the battery charging algorithm itself is minimally affected.
How to find the bit depth if the phone does not turn on?
If the device does not turn on, software methods will not work. The only option is to find the exact model of the device on the case or box and look at its technical characteristics on the manufacturer’s official website or in specialized databases such as GSMArena.
