So I've had issues using android auto (music freezes after 10mins), so have up and just use the car apps in PCM. Including navigation.
When you put a destination in and do a route, it displays a battery level % in the screen. I assume this is telling me how much battery I will have left when I arrive at my destination.
But the level the screen displays is ALWAYS wrong. And not by like a few %s, but by like 20-30% (???).
So does that number mean something else? Is there some setting I have to change somewhere? Or is this just ANOTHER example of something that's broken with car software?
Example #1.
I drop my kids off at school. I put my house into my nav and set it as a destination route. It is about 2min drive and barely 0.5 miles away. My battery shows at 47%. The nav shows the battery level next to destination as 40%. (?? So 7% to go less than half mile ??)
Example #2.
Driving to an appt, enter into nav. It says 20min, 14 miles away. My battery is at 55%. Nav shows battery next to destination info as 40% (?? So 15% to go 14 miles ??).
Example #3.
Driving to an event. Enter nav. 16min, 10 miles away. Battery at 61%. Nav shows it as 47%. (?? So 14% to go 10 miles ??)
I have MANY more. It is wildly inaccurate. Never even close. When I arrive at destination, a fraction of battery and range is used.
So is this normal for everyone?
