Does query caching reduce the amount of Firestore reads?

I am experiencing a strangely high amount of reads on my app at the moment.

My app it's an event app with multiple lists of different events, is it possible that each time a user opens an event and then comes back to the events list page this would trigger again all the reads for the documents that are present in the list ?

If yes would query caching solve the problem and should it be set up on a page level or on an app level ?
