Added on October 18, 2010, 3:16 pmI'm using cgynett and somehow the rate of charging/consuming almost equal. The battery percentage does not change at all when using GPS. This is with 3GS though. I have yet to try with iP4
Added on October 18, 2010, 3:30 pmIt's one of the earliest bug that I have reviewed in the AppStore as well. Lagginess that does not suit the capacitive screen.
In terms of the position lock, this is my theory. If one is to compare with GarminXT, they have what they call as "Show Location" function, can be found in the Map setting. There are two options, 1. On roads 2. At GPS location.
Those that pick "on roads", obviously will always see their car on the road, no matter how fluctuates the GPS signal is. If they choose the other one, it will show the most accurate GPS position at the moment and hence will show you out of the road position.
My point is, GPS signal is fluctuating depending on your location. Garmin has solved this issue by giving you the function stated so it will looks better on the map eventhough actually the GPS locked you adjacent to the road.
P/S: those claiming slow GPS lock, could you please inform us whether your AGPS aka Location Services is on or not?
Im abit confused here..
