Power Management

Since KNULLI Firefly, the CFW comes with a Power Management menu, where you can adjust settings to save some battery life. To reach the Power Management menu, press Start to bring up the main menu, head to System Settings, then Power Management.

Battery Saving Modes

KNULLI comes with 3 different battery saving modes: Dim dims the screen to lower its battery consumption, Suspend puts the device in sleep mode, and Shutdown shuts the device down gracefully.

The selected battery saving mode will kick in once the user has been idle for a given amount of time which can be set up via Idle Time. You will be able to set up values between 1 and 60 minutes.

RG35XX SP Lid Support

The RG35XX SP is a clamshell device. KNULLI supports either going to sleep mode or shutting down the device when closing the lid. By default, closing the lid of the RG35XX SP will put the device in sleep mode. However, sleep modes on the Anbernic devices of the H700 series are not very efficient.

If you want to switch the lid behavior to shutdown, press Start to bring up the main menu, head to System Settings, then Services. There you will find a service called LID_SHUTDOWN. Enable this service to shut the device down automatically when you close the lid.

KNULLI saves your progress on shutdown (if the emulator supports auto-save)

RetroArch cores support auto-save when exiting the emulator. You can enable this option in the Game Settings menu. If you trigger a shutdown by holding the power button or closing the lid while you are playing a game with a RetroArch core and auto-save enabled, KNULLI will exit the emulator gracefully and let it perform auto-save before the device is shut down.
