Desktop speed improved, mobile not

I installed the plugin and my desktop speed is definitely improved, but my mobile score is way too low. Is it only improving desktop speed? my site is gadget-freakz.com

I use latest wordpress, magazine theme, wp-rocket and Cloudflare.
Improving the speed with my knowledge is very difficult, what can I do to improve?
