## Optimizing Performance
|
|
Optimizing for performance will have significant impact on battery life, however it will provide the best experience for more demanding emulators.

## Optimizing Battery Life
|
|
JELOS includes an `Enhanced Power Saving` mode which is available in the `System Settings` menu. This option provides a variety of sub options that when enabled tune your device for optimal battery life without immediately sacrificing performance.
|
|
|
|
|Feature|Function|May Affect Stability|
|
|
|----|----|----|
|
|
|CPU Power Saving|Tunes the CPU/SoC to preference battery life over performance.|No|
|
|
GPU Performance Profile<sup>1</sup>|User configurable to force the GPU into the preferred performance state|No|
|
|
Audio Power Saving|Enables the audio device to operate in a low power mode.|No|
|
|
PCIE Active State Power Management|Forces a low power state for PCI and PCIe connections.|Yes|
|
|
Enable Wake Events|Enables PCI wakeup signalling to allow devices to enter low power states.|Yes|
|
|
Runtime Power Management|Enables USB idle power management, and configures usb devices to autosuspend.|Yes|
|
|
|
|
### Recommended Settings For Optimal Battery Life
|
|
Enable Enhanced Power Saving, and enable all options. If the device has undesired behavior, disable the options that may effect stability and reboot the device.
