Performance and Battery Life Optimizations

Optimizing Performance

Optimizing for performance will have significant impact on battery life, however it will provide the best experience for more demanding emulators. Begin by disabling Enhanced Power Saving in the System Settings menu.

Optimizing Battery Life

JELOS includes an Enhanced Power Saving mode which is available in the System Settings menu. This mode tunes your device for power saving, but does not enable options that may affect performance. The table below provides general recommendations to achieve the best possible battery life. Additional adjustments may need to be made to individual emulators or games for the best balance of performance and battery life.
