| Enable Performance Mode |
Performance mode adjusts power settings to deliver maximum performance. This will cause the battery to drain more quickly, especially when graphic-intensive apps are used.
When the battery level is sufficient, go to 
(or 
Optimiser > 
) and enable Performance mode.
The 
icon will then be displayed in the status bar.
Performance mode is not available on some devices. If this option is not displayed in Optimiser, it indicates that your device does not support the feature.
Thanks for your feedback.
