Xamarin Developer for google calender

I have a problem with an Android app. The app is a simple calendar display and pulls data from Google Calendar to display availability of our meeting room. This is working nicely. However the app needs to run forever without any user interaction, but for some reason the update stops after a while and the screen is frozen instead of updating. This could be related to some power management settings or a memory leak or something similar. I cannot reliably pinpoint the issue, but when the app runs for more than 1-2 days the problem appears.
