On a road trip I took in May, Waze couldn't seem to stay connected on either of two iPhones. Google Maps had no such issues. I'm not sure why that would be allowed to happen, given that Google owns Waze anyway.
Funny you mention that - this has happened a handful of times lately and I am not sure why. The network is completely lost and I have to quit and reopen the app on my iPhone for it to work again. I assumed it was due to my carriers (o2 germany) general unreliability..
Waze is much more of a CPU and bandwidth hog, it's quite possible your phone is just overheating and throttling especially if it is also charging st the same time and getting hit by sunlight.
Ha! Thanks, quite likely as i notice it overheating frequently when navigating and never connected it to waze. Will keep an eye on it and compare to Google Maps. Would be reason enough for me to switch backt ..
