| 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 display in the status bar.
Thanks for your feedback.
