WordPress: CPT posts per page

I have a WordPress CPT with custom taxonomies. I want the mobile to show all posts on one page, but tablet and desktop to only show 6 posts per page.

I have some php to do this:

function aa_order_cpt( $query ) {

if ( is_admin() || ! $query->is_main_query() ) {
    return;
}

if ( is_archive() ) {
    $query->set( 'order' , 'des' );
    $query->set( 'orderby', 'date');
    $query->set('posts_per_page', -1 ); // mobile - all

    if( $query->is_main_query() && ! wp_is_mobile() ) {
        $query->set('posts_per_page', 6);
    }

    return;
}

} add_action( 'pre_get_posts', 'aa_order_cpt', 1 );

The code doesn't work because wp_is_mobile isn't great and uses this for tablets too.

I need to determine the width of the viewport, which I know I can do with jQuery, but how do I set the posts per page using jquery?

Thanks
