No, this doesn't sound normal. One possibility I can think of - if you are making changes on both the desktop and the phone without syncing in between, it can take a lot longer for the changes to get merged - it's much more work than if you've only got changes on one side or the other to be merged. If that's your problem, try making sure that you have each client synced up when you leave it and when you enter it and things should be a good bit faster.
