Smartphone performance is not only the number of processor cores or the amount of RAM indicated in the specifications. The actual power of the device depends on firmware optimization, battery condition, temperature conditions and even the Android version. If your phone has started to slow down or you are planning to buy a used device, it is important to be able to objectively assess its capabilities.

In this article we will examine 7 proven methods measure the power of an Android device - from standard system tools to professional benchmarks. You'll learn how to interpret test results, what to look for when comparing with other models, and why Samsung Galaxy S24 Ultra may perform worse than Redmi Note 12 Pro+ in some scenarios. We will also reveal hidden Android parameters that manufacturers do not advertise, but which directly affect the speed of operation.

1. Standard Android tools: what you can find out without third-party applications

Before installing benchmarks, check the basic system parameters. They will give an idea of ​​the hardware and the current state of the device.

Open Settings → About phone. Here you will find:

  • 📱 Processor model (for example, Qualcomm Snapdragon 8 Gen 3 or Mediatek Dimensity 9200+). This is a key indicator of power.
  • 🧠 Amount of RAM. Please note that 1–1.5 GB less is actually available to applications due to system processes.
  • 🔄 Android version. New versions (Android 14+) are better optimized, but may require more resources.
  • 🔋 Battery status (in some firmwares). A worn-out battery (>80% of cycles) forcibly reduces performance.

For more detailed information, go to Settings → System → Developer Options (if the section is hidden, activate it by pressing 7 times on Build number in the "About phone" section). Here, pay attention to:

  • ⚡ Background process limit (optimally - 4 or more).
  • 🎮 Game optimization (enabled/disabled).
  • 🔍 USB debugging (allows you to use ADB for deep diagnostics).
⚠️ Attention: On some devices (for example, Xiaomi or Realme) developer options may be reset after a system update. Check them before tests.

2. Benchmarks for Android: which tests show real power

Standard tools provide only general information. For an accurate assessment, use specialized benchmarks. They simulate the load on the processor, graphics and memory, giving comparable scores.

Top 3 benchmarks for Android in 2026:

Application What it tests Pros Cons
Geekbench 6 CPU (single/multi-core), GPU (OpenCL/Vulkan), memory Cross-platform, detailed reports Paid version for full functionality
AnTuTu Benchmark CPU, GPU, UX (interface), memory Free, popular for comparing smartphones Results may be inflated on some chipsets
3DMark Wild Life Graphics performance (Vulkan) Realistic load, comparison with PC The device heats up a lot

How to conduct tests correctly:

  1. Close all background applications (use Settings → Applications → Open).
  2. Connect the charger - a low battery reduces performance.
  3. Repeat the test 2-3 times and take the average (the first run may be slower due to caching).
  4. Compare results only with devices running the same version of Android and firmware.
⚠️ Attention: Manufacturers (for example, OnePlus or Oppo) sometimes optimize the firmware specifically for benchmarks, inflating the results. Check the actual performance in games or heavy applications.

3. Hidden performance parameters: what benchmarks do not show

Even high scores in tests do not guarantee smooth operation in real conditions. Performance is affected by hidden settings that are not displayed in the standard interface.

How to check them:

  • 🔧 Throttling: When the processor overheats, it automatically reduces the frequency. Check using CPU Throttling Test (available on Google Play If the frequency drops below 70% of the maximum - the device). overheats.
  • 📉 Limiting background applications. processes: Some firmwares (for example, MIUI or ColorOS) aggressively close applications. Check in Settings → Battery → Optimization.
  • 🖥️ Screen resolution: Many flagships operate in FHD+ mode instead of native resolution (for example, Galaxy S23 Ultra can use 2316x1080 instead of 3088x1440, but this reduces the load on the GPU). degrades the image quality.

For deep diagnostics, use ADB (Android Debug Bridge). Connect the phone to the PC and run the commands:

adb shell cat /proc/cpuinfo # Information about the processor

adb shell cat /proc/meminfo # Memory status


adb shell dumpsys power # Energy consumption data

Pay special attention to the parameter scaling_cur_freq v /sys/devices/system/cpu/cpu0/cpufreq/ —it shows the real frequency of the cores at the moment. If it is below the maximum without load, this is a sign of throttling or power saving.

How to enable display of the real CPU frequency

1. Install CPU Monitor from Google Play.

2. Provide root access (if available) or use ADB.

3. In the application settings, enable the "Show current frequency" option.

4. Launch a heavy application (for example, a game) and observe the changes.

4. Testing in real conditions: games and multitasking

Benchmarks show “raw” power, but not take into account the optimization of the firmware for real tasks. The best way to evaluate performance is testing in familiar scenarios.

Game tests:

  • 🎮 Run Genshin Impact at maximum settings (60 FPS, Ultra) If FPS drops below 40, the device is weak for modern games.
  • 🏎️ Check Asphalt 9: Legends with all effects enabled. Lags when loading textures indicate a weak GPU or slow memory.
  • 🔫 In Call of Duty: Mobile select mode Maximum settings + 90 FPSIf the game automatically reduces. quality - the processor is not up to par.

Multitasking test:

  1. Open 10 tabs in Chrome (including YouTube videos).
  2. Launch Google Maps with navigation.
  3. Open Telegram and scroll through the feed with GIFs.
  4. Switch between applications If they restart, there is not enough RAM.

For objectivity, use GameBench —the application records FPS, energy consumption and temperature during the game. Compare the results with the reference values for your model on the manufacturer's website.

💡

If FPS drops are observed in games, but benchmarks show high results, check the graphics settings in the game itself (for example, PUBG Mobile) automatically reduce quality on non-certified devices.

5. Comparison with other devices: where to look for objective data

To understand how powerful your smartphone is compared to others, use benchmark databases and independent reviews. But keep in mind that the results may differ even for the same models due to different firmware or regions.

Where to look for data for comparison:

  • 📊 Official benchmark sites:
    • Geekbench Browser (browser.geekbench.com) - filter by model and version of Android.
    • AnTuTu Ranking - monthly top smartphones in terms of performance.
  • 📱 YouTube channels:
    • TechTablets —comparative tests of flagships.
    • MrWhooseTheBoss —reviews with an emphasis on real performance.
  • 📝 Forums:
    • 4PDA —topics with user tests and firmware.
    • XDA Developers —discussion of optimization and overclocking.

When comparing, pay attention to:

  • 🔄 Firmware version. For example, on Android 13 it may be slower than on Android 14. Samsung Galaxy S22 May be slower on Android 13 than on Android 14.
  • 🌡️ Temperature conditions. Tests in a cold room will show higher results.
  • 🔋 Battery condition. A worn battery (>300 cycles) reduces peak power.
⚠️ Attention: Some manufacturers (for example Huawei) block access to benchmarks in their firmware. In this case, use ADB or alternative testing methods.

6. Performance evaluation via ADB: for advanced users

If you need the most accurate data, use Android Debug Bridge (ADB). This tool allows you to obtain low-level information about the operation of the system, which is not shown by standard applications.

How to connect:

  1. Download Platform Tools from the website Google and unpack it on your PC.
  2. Enable USB debugging in the developer settings on your phone.
  3. Connect your phone to the PC and run in the command line: 
    adb devices

    (your device should be displayed).

Useful commands for diagnostics:

Command What it shows Example output
adb shell top -m 10 Top 10 processes by CPU consumption PID 1234 com.android.chrome 35% CPU
adb shell dumpsys meminfo Use of operational memory MemTotal: 7.5 GB, MemFree: 1.2 GB
adb shell cat /proc/gpuinfo Information about the GPU GPU: Adreno 740, Frequency: 680 MHz
adb shell wm size Current screen resolution Physical size: 1080x2400

For continuous monitoring, use:

adb shell top -d 1 -m 5 | grep "CPU"

This command will display the top 5 processes every second by CPU load.

💡

ADB allows you to detect hidden problems that are not visible in benchmarks. For example, if a process mediaserver constantly loads the CPU by 20%+, this is a sign of an error in the firmware or a hardware problem.

7. When there is not enough power: how to optimize performance

If tests show that your smartphone is weaker than expected, do not rush to change it. In most cases, performance can be improved using software methods.

Top 5 ways to speed up Android:

  • 🧹 Cleaning the system:
    • Delete the application cache in Settings → Storage → Cached data.
    • Use SD Maid to remove garbage (remnants of deleted applications, empty folders).
  • ⚙️ Disable animation:
    • In the developer options, set: Window animation = Off, Animation of transitions = Off., Animator duration = Off.
  • 🔄 Reset to factory settings:
    • Before resetting, make a backup via Swift Backup (root required).
    • After resetting, do not restore applications from backup - install them again.
  • 🔋 Replacing the battery:
    • If the battery capacity drops below 80%, the system forcibly limits performance.
    • Check the battery status via AccuBattery.
  • 📱 Custom firmware:
    • For older devices (for example, Google Pixel 4), installing LineageOS or Pixel Experience can give +20–30% performance.
    • Use OrangeFox Recovery to install.

If all else fails, consider an upgrade. In 2026, the optimal price/performance models:

  • Redmi Note 13 Pro+ (Dimensity 7200 Ultra) - the best budget option.
  • Google Pixel 7a (Tensor G2) - excellent software optimization.
  • Samsung Galaxy S23 FE (Snapdragon 8 Gen 2) - flagship average power price.
What to do if the smartphone heats up and slows down during tests?

Overheating and performance drops are often associated with:

  • 🔋 Worn out battery (replace the battery).
  • 🧊 Clogged cooling system (clean at a service center).
  • 🔄 Non-optimized firmware (update the software or install a custom one).
  • 🎮 Background processes (check in Settings → Permissions → Special access → Using others applications).

If the problem persists, try limiting the maximum CPU frequency via Kernel Auditor (root required). This will reduce performance but eliminate overheating.

Can you trust the benchmark results on Chinese smartphones?

Manufacturers from China (for example, Xiaomi, Oppo, Vivo) often optimize firmware specifically for benchmarks, overestimating the results by 10-20%. To get fair data:

  1. Before the test, reboot your phone and wait 5 minutes (for temporary boosts to reset).
  2. Use Performance Mode in the battery settings (if any).
  3. Compare the results with independent reviews (for example, on GSMArena or NotebookCheck).

For objectivity, test the device in real scenarios: games, multitasking, video rendering.

How to check the power of a smartphone without installing applications?

If you cannot install benchmarks (for example, on a work phone), use:

  • 🌐 Online tests:
  • 📊 Hidden menus:
    • Enter in the phone application ##4636## → select “Battery information” and “Usage.”
    • For Samsung: #0# → sensor and display test (indirectly shows stability system).
  • 🎮 Game tests:
    • Run Google Earth and scroll the 3D card - if there are no lags, the GPU is fine.
    • Open Chrome and scroll a complex web page (for example, WebGL Samples).

These methods are less accurate than benchmarks, but will give a general idea of ​​power.

Which processors are considered powerful in 2026?

Current rating of chipsets by performance (based on AnTuTu v10 and Geekbench 6):

  1. Flagships:
    • Snapdragon 8 Gen 3 (1,500,000+ in AnTuTu) - Galaxy S24 Ultra, Xiaomi 14.
    • Dimensity 9300 (1 450 000+) — Vivo X100 Pro, Oppo Find X7.

Why is a new smartphone slower than an old one?

Reasons for an unexpected drop in performance:

  • 🔄 Firmware update: New versions of Android may be less optimized for your device. For example, Samsung Galaxy S20 on Android. 13 works slower than on Android 12.
  • 🔋 Battery wear: After 500 charging cycles, the system forcibly limits performance.
  • 📱 Bloatvar (pre-installed applications): Manufacturers add unnecessary services that load the system. Check. in Settings → Applications and disable unnecessary ones.
  • 🌡️ Thermal throttling: If the temperature sensor is broken, the phone constantly works in low power mode.
  • 🛠️ Hardware problems: Damaged memory or processor (for example, after a fall).

To diagnose the problem:

  1. Reset the phone to factory settings (without restoring from backup).
  2. Check the battery status via AccuBattery.
  3. Install custom firmware (for example, LineageOS) - if the device has become faster, the problem is in the stock software.
