App on iPhone plans a different slower route than my Go 5000

Hi, has the route planning algorithm on the iPhone app been changed? I have the setting as 'Faster Route' but lately journey times are getting longer. As a comparison I have compared journey times on the app to the journey times on my old TomTom Go 5000. On an identical trip, the app plans for a journey taking 1hr 30 mins but the Go says that the same journey will take 1 hour 5 mins and plans a completely different route to the app. I have live traffic on both. The live traffic icons on both confirm that it is working so why does the app plan to take 25mins longer, on a more complex route, than the Go 5000? This is not a 'one off' - I have seen this on a few journeys in the last week or so.Thanks
