Play Booster: Junk File Cleaner on PC and Mac

About the Game

Keeping a smartphone running smoothly over time takes more than just deleting old photos. Cache files pile up, background apps drain power, and permission-hungry software quietly collects data you never intended to share. Booster: Junk File Cleaner was built to address all of these issues in one place, offering a collection of maintenance and security tools that work together to restore speed, extend battery life, and protect user privacy.
At the heart of the app is its junk file cleaning engine. Over time, apps generate temporary files and cached data that accumulate in storage without offering any ongoing benefit. Booster scans the device to locate these files using intelligent detection algorithms that distinguish between recoverable junk and data you actually want to keep. The result is a cleanup process that frees up meaningful amounts of storage space without putting personal files at risk. Users are often surprised by how much space a single scan can recover, particularly on devices that have been in use for months or years without a proper cleanup.
Memory management is another core strength. When too many applications run in the background simultaneously, overall system performance tends to suffer. Booster's RAM optimization feature clears out idle processes to restore available memory, which leads to faster app launches and more responsive navigation throughout the device. For users who spend time gaming, there is a dedicated game speed mode that prioritizes resources toward active titles, helping frame rates stay consistent during play sessions.
Battery life is a common frustration for smartphone users, and Booster approaches the problem from a practical angle. Rather than simply dimming the screen, it identifies applications that continue consuming power in the background even when they are not actively in use. By closing these processes automatically, the app extends the time between charges in a meaningful way. This is especially useful for people who need their phones to last through a full day without access to a charger.
The CPU cooling function monitors processor temperature and steps in when the device begins to heat up. Sustained high temperatures can affect both performance and long-term hardware health, so having an automated tool that reduces thermal load with a single tap adds a practical layer of device care.
Booster also takes privacy seriously through its real-time security scanning feature. Key highlights of this function include:
Scanning installed apps for excessive permission requests that go beyond what those apps reasonably need
Flagging applications that could potentially access or expose sensitive personal data
Giving users a clear summary of privacy risks so they can make informed decisions about which apps to keep or remove
Providing one-tap resolution to quickly address identified threats without navigating through system menus
The overall design philosophy behind Booster centers on simplicity without sacrificing depth. Every major function is accessible from the main dashboard, and the one-tap optimization option covers junk cleaning, memory boosting, and battery management in a single action for users who prefer a hands-off approach. For those who want more control, each individual module can be run independently.
Running Booster through MuMuPlayer on PC brings the full feature set to a larger display, making it easier to read detailed scan reports and manage security alerts. The stable environment provided by MuMuPlayer ensures that scans complete without interruption, and navigating the app with a mouse and keyboard makes the process faster and more comfortable for regular maintenance routines.
