Redmi note 3 pro performance mode

Hi, i have a redmi note 3 pro and when i run antutu benchmarks i get around 50k but when i see other peoples results they get above 70k.

I have miui global 7.1.8.0 installed and i cant seem to find performance mode within battery settings. Im assuming thats y my scores are poor, could anyone help me out in finding performance mode please?

Thank you
