We have an app for that, specialised in optimising not only your performance score for mobile but also the UX.
Have a look Mobile‑optimized Product Pages
You can ping me if you have questions
Thanks all for your interest and early feedback. After initial testing, we have decided to focus on optimizing store speed by intelligently loading 3rd party scripts. This improves page speed scores by at least 20 points and in most cases, 40+ points.
Our app is now open to everyone. Please check https://apps.shopify.com/core-web-vitals-booster. We are keeping the app FREE forever for the first 100 users.
We plan to periodically release new features that boost store speed even further.
