Modern displays utilize adaptive logic to alternate frequencies between 60Hz and 120Hz based on display content. Unfortunately, aggressive software optimization often drops performance back to 60Hz during demanding mobile games, leading to stuttering.
For long trips or low-battery situations, a static 30Hz cap extends screen-on time (SOT) significantly beyond standard factory battery saver modes. Installation and Technical Requirements
Go to your device Settings > Security to allow the installation of APKs from third-party sources.
Open the app and select your desired refresh rate. Important Considerations and Risks While tools like this are useful, they come with risks:
Android systems naturally use dynamic switching to toggle between high and low refresh rates based on the app running or the current battery percentage. While helpful for battery life, it can limit games to 60Hz or introduce jarring visual stutters when the operating system abruptly lowers the frequency.
