I realize this is a worse case scenario, but i used my phone as navigation for the first time today and after maybe 20 minutes of having it on my dash, charging, listeing to bluetooth music while navigating it quit charging and the red notification light started blinking. I had power saver on with the screen at its lowest Automatic Brightness set. I know this is a stress test for it, but lots of other phones I've had didnt have a problem like this. I dont use it as navigation too often, but it cant not charge if i do use it that way.
Anyone elses do this too?
