You can try this code by following these steps:
Step 1: Go to the online store ->Theme ->Edit Code.
Step 2: Find the theme.liquid file and add the following code before the </head> tag

<style>
@media screen and (max-width: 749px) { 
  div#Slider-template--15789192380479__slideshow_hLzmKi {
   height: 225px;
  }
}
</style>

Result:

But I think you need to change the image on the mobile.
Hopefully it will help you. If yes then Please don't forget hit Like and Mark it as solution!
