Lags when scrolling on the phone

[Brikus]

Hello everyone, I have a problem on the site, that scrolling slows down, on the phone it slows down the most, when I go to All products, then when I scroll, it just slows down 10 frames per second. I have already tried everything and reduced the image size. But I decided to check on another topic, then everything worked well, scrolled quickly, if you can, then help and write.

If anything, I am not very good at codes

I would be very glad if you could remove the extra code for me later.
