How can we calculate the mobile app screen navigation load time?

Hi Team, I need to calculate the Mobile app Page loading time when we navigate from one screen to other screen for Mobile Application.

I have Tried below Approach:

Before Clicking on Element, get the current Time in MS and after clicking on the element, Waiting for expected element to be visible then again getting current time in MS and Subtract the times.

Please Help me out with better approach to calculate accurate page load time.

Thank you.

Best way is to get Developers involved to instrument the build and log these times. Your approach is better than nothing, but measurements of this type outside the app will always be imprecise.

@wreed Thank you for your valuable inputs.
