Which is why I have a car charger. It goes on it when needed.
However, turning off Wifi defeats the purpose of having a notification that tells you Wifi is available. So it does go without saying that WiFi is searching hehe. It's merely an option for those who didn't know it was there and wish to use it. I probably could of worded my post better, too.
