Good day, Alexander!
I can figure out the problem of the slow website on mobile and find the real reason (not just "tweak the numbers").
What I will do:
Full speed audit
Check animations, JS, and third-party scripts (they often cause lags)
Analyze the difference between users (network, cache, geo, hosting)
Check the server/hosting (TTFB, load)
Optimize the mobile version (resources, lazy load, render)
Fix bottlenecks that really affect speed
I work with cases where "it works for some, it doesn't for others" — usually, the reason lies in the combination of JS + network + cache.
A few clarifications:
What is the website built on (WordPress or another CMS)?
Is there access to the hosting/server?
Are analytics/scripts (chat, trackers, etc.) connected?
You can provide access or the website — I will quickly find the reason and suggest specific fixes.
