To high LCP on mobile devices

Maybe you are right… My site has about 17.000 visitors in a month and I did really some tests on the live site – I think I run such tests only on a test site which is not affecting the online site at all.

Is it possible that the code mentioned by ejcabquina only works for desktop?

add_action( 'wp', function() {
    remove_action( 'generate_before_content', 'generate_featured_page_header_inside_single', 10 );
} );

That code should work on both desktop and mobile ??

Thank you for answering, I already thougt it works for mobile and Desktop. But is it possible that it only works for Desktop?

Hi there,

that function applies to ALL device sizes there is no simple way to make it apply to a specific device.

Hi David, no problem! The LCP started decreasing on Desktop and also the FCP is getting better scores. Only the CLS stays the same (0,15) even there is no measureable CLS. But now I’m getting a problem with mobile that wasn’t there before. The FID is increasing about 2 seconds a day and total blocking time is about 4,8s. Have you any idea, what can be the reason for it?

How much of your timings are coming from Real World traffic or from you testing the site?

Hi David, most of the timings comes from real world traffic ?? I have already found the reason for the growing FID. The GPDR Plugin loads Google Analytics when the rest of the site is also loaded. That has no impact on the desktop site but unfortunately it increases time to interactive and in further consequence the FID. Until recently I always loaded Google Analytics with a delay of 3 seconds so that there wasn’t any impact on site rendering. Unfortunately this doesn’t work anymore with the GPDR plugin in that way. So I have to find another way ??

Glad you found the issue – and thanks for sharing what the problem was!
