Following my post yesterday comparing Runkeeper stats on the iPhone 3G compared to the iPhone 4 (both devices running the same version of Runkeeper 2.3.0.4 under iOS4), I did another test today to see whether the improved tracking on iPhone 4 was just a one off or a definite improvement of this newer device.
The image below shows the route captured using an iPhone 3G on the left and the same route (captured at same time) from the iPhone 4.
Are the parameters the same?
Seems like the gps update interval is set to a different amount on the i3 and i4, with i4 being say every second while the i3 looks to be every minute
