Do these help with mobile performance?

I'm exporting to cordova and building an android app.

The performance is really bad and I'm wondering if minifying the script at export improves the performance or not, maybe it doesn't even make a performance-difference?

Also, PNG compression, should I maybe use brute?

Performance tips

Minifying helps protect your game against reverse engineering, and both minifying and PNG recompression can help reduce the download size, but you should not expect either to affect runtime performance.

Ok, thanks Ashley
