Even if you were able to achieve this (via rooting or a specific device exploit), forcing all CPU cores to run at maximum frequency 100% of the time is generally a bad idea for the following reasons:

Applications available on the Google Play Store that claim to maximize CPU cores without root generally operate by manipulating the software layer accessible to standard users. They typically function in one of two ways: by applying a "High Performance" profile available in the user’s existing kernel (if supported by the manufacturer) or by running background processes that generate artificial load. In the latter scenario, the application keeps the CPU busy, preventing the system from entering low-power states. This forces the CPU to maintain higher clock speeds.

: This app allows users to manually activate specific CPU cores (e.g., the first 4 for quad-core or 8 for octa-core devices) to ensure they run at maximum speed without requiring root.

: Check your device's core count using lscpu .

. While these tools claim to enhance gaming performance, they often function by generating artificial load rather than true system-level overclocking. Google Play Common Apps and Tools
