Phone Clean-Booster, developed by chenjack, is a free and professional cleaning app for Android users. It provides a one-tap solution for cache cleaning, junk cleaning, storage cleaning, RAM freeing, space freeing, CPU cooling, and battery saving. The app offers a quick scan function that cleans up excess junk in one click, making it a smart cleaner app.

The app is designed to optimize CPU usage and stop overheating apps, which helps to cool down the CPU temperature. It also analyzes the battery usage of the phone and terminates apps that cause battery drainage. However, to provide better functions for garbage cleaning and system optimization, the app requires the MANAGE_EXTERNAL_STORAGE permission of the device. After obtaining this permission, the app helps to clean up system junk files, including cache junk, ad junk, and residual junk.

Overall, Phone Clean-Booster is an efficient and comprehensive cleaning app that provides a hassle-free solution for Android users looking for an all-in-one cleaning app.
