A CPU (Central Processing Unit) is among the most critical components of modern-day smartphones. It’s responsible for executing instructions and performing calculations for various tasks, ranging from basic operations to complex computations. Due to its importance, CPU optimization has become a popular topic among Android users. Many apps claim to optimize CPU performance, but not all of them deliver reliable results. Therefore, finding the best CPU app for Android can be a daunting task for many users.
When it comes to CPU apps, there are two types available: those that aim to optimize CPU performance and those that provide information about the CPU. Optimization apps usually work in the background, adjusting settings and processes to maximize CPU speed while minimizing energy consumption. Information apps, on the other hand, display real-time data about CPU usage, frequency, temperature, and other relevant metrics.
We have compiled a list of 8 Best Cpu App For Android for your consideration, which have undergone rigorous testing and evaluation by our team of experts.

3. Energy Bar – A pulsating Battery indicator!
The Energy Bar app adds a configurable energy bar at the top of the user’s screen to display the current battery level. When the device is plugged in to charge, the app displays a pulsating animation that indicates not only the current battery level but also how much the battery has charged since plugging in. The length of the energy bar changes in proportion to the battery level, covering the whole width of the screen when fully charged and depleting as the battery drains.
The app is available for several devices, including OnePlus 8, OnePlus 8 Pro, Galaxy A51, A71, Z Flip, Galaxy S20/Ultra/5G/+, Galaxy S10/e/5G/+, Galaxy Note 10/5G/+, S8/S9/S10/+, and Note 8/9. The latest update integrates Energy Bar with the device’s accessibility service, making it more reliable and fitting well with the system. The user can also configure the bar’s width, origin, and color scheme.
Energy Bar consumes almost 0% load on the CPU and only wakes up to reflect any change in battery level. It goes into deep sleep mode when the screen is turned off to conserve battery. Android requires Energy Bar to run as an accessibility service to display on the lock screen, which is useful for people with visual disabilities. However, there is a possibility of screen burn-in on AMOLED devices, although there have been no complaints so far.
4. Sensor Box for Android
Sensor Box for Android is an application that detects all available sensors on an Android device and displays their functionality with high-quality graphics. The app also provides information on which sensors are supported by the device’s hardware and includes useful sensor tools for daily use.
The app includes various sensors such as the gyroscope sensor which measures six directions simultaneously, mostly used in 3D game development and indoor navigation. The light sensor detects light intensity in the surroundings and adjusts screen brightness and keyboard light accordingly. The orientation sensor detects the device’s direction status and can be used as a measure equipment like a spirit level.
The proximity sensor measures the distance between two objects, usually between the device’s screen and our hands/face, while the temperature sensor provides information about the device temperature. The accelerometer sensor detects the device’s direction and is widely used in game development. Sound detects the sound intensity around you, and the magnetic field is used for metal detection and compass.
Pressure is used to detect environmental pressure to forecast weather and temperature. Sensor Box for Android only detects changes and may not show the correct temperature, proximity, light, and pressure values if no changes occur.
For better performance, sensors are usually used together, and the app provides a live demonstration for this purpose. To give feedback, users can contact the app developers via email.
5. CPU X – Device & System info
CPU X is an Android application that provides users with detailed information about their devices, including processor, cores, speed, model, RAM, camera, and sensors. The app also enables users to search for other Android smartphones and view their specifications.
Moreover, the app features an Internet speed monitor that displays current download and upload speeds in notifications and combined speed in the status bar. Users can also monitor their battery by viewing the charging or discharging electric current in milliamperes and the temperature of the battery in notifications.
In addition, CPU X offers the latest technology updates and informative articles through its news and articles section. The app also provides a dedicated forum where users can ask and answer questions.

Finally, CPU X provides a semi-transparent widget on the home screen that displays at-a-glance information about the device’s important status.
6. CPU-Z
CPU-Z is a free Android application that provides users with information about their device. It reports on the System On Chip (SoC) name, architecture, and clock speed for each core, system information including brand and model, screen resolution, RAM, and storage, battery information such as level, status, temperature, and capacity, and sensors. The application requires Android 2.2 and above (version 1.03 and +) to run.
To use CPU-Z, two permissions are required: INTERNET permission for online validation and ACCESS_NETWORK_STATE for statistics. The online validation allows users to store their Android device’s hardware specifications in a database. After validation, the program opens the user’s validation URL into their current internet browser. If an email address is entered, an email with the validation link will be sent as a reminder.
For version 1.03 and above, if CPU-Z closes abnormally, the settings screen will appear at the next run. The user can remove the main detection features of the application on that screen to make it run. In case of a bug, the user can open the application menu and choose Send Debug Infos to send a report by email. The FAQ can be found at http://www.cpuid.com/softwares/cpu-z-android.html#faq.
7. Simple System Monitor
