We are developing a mobile application using Ionic Platform that uses internally the Android System Webview to render the application, and we are facing random slowness on different Android devices, As per below grid, the application start-up can vary from 7 sec to 27 sec.
Please could you advise what could be the reason of this slowness ? This slowness is mainly appearing on latest devices ( latest Android 11/12 ) and not on old devices ( Android 8/9/10 ). Please could you feedback and recommend how we should fix this issue ? Is there some specific settings to be done on these devices to accelerate the performance and make it stable? ( We have noticed that on latest devices there is an option related to power saving that can limit the CPU usage to 70% , we have disabled it but it didn’t helped. )
