Wi-Fi off effect on assisted GPS?
Wondering if anyone can answer a un-googleable question.
With Wi-Fi off and opening the native iPhone map app there is always a pop up message saying GPS accuracy improves with Wi-Fi on and has a button to go right to settings to turn it on. Okay, I know GPS accuracy is improved while connected to Wi-Fi, but is it improved even when not connected but turned on?
Thinking maybe just having Wi-Fi on searching and locating connections may pinpoint your location relative to Wi-Fi routers and/or hot spots along your route and help with positioning and tracking. I know this would kill the battery but am neurotic enough about my GPS tracking apps to do it anyway.
My experiments with this are inclusive. May seem like a silly question but like I said I'm neurotic about my GPS accuracy. So, does anyone know for sure one way or the other?
Thanks.
