If a page has more than 5 related lists or more than 25 fields in the record detail, users can encounter performance issues when viewing the page in the Salesforce mobile app.
In the Performance Analysis for App Builder tool:
Components that are restricted to the desktop form factor via a visibility rule aren’t included in the phone form factor performance assessment.
Analysis of page performance on a phone is available only on pages whose template supports the phone form factor.
Components aren't the only factors influencing page load time, so the numbers in the component impact chart don't add up to 100% of the predicted page load time.
Analysis of pages for the desktop form factor is measured in seconds. For the phone form factor, the page is scored based on the components that are visible when the page loads on a phone.
User metrics are org-specific or page-specific data. Previously activated pages display metrics from visits to that page. New pages display metrics from visits
