I'll have to double check my phone when I get out of work.. But I had an iPhone X and about 90% of the time it never unlocked for me. (Only thing I did not check was "Background App Refresh"). I just recently upgraded to the iPhone 11 pro and I'm still having the issue.
I'll double check that...
There are also a ton of trip planning websites for EVs specifically. I use A Better Routeplanner like it's going out of style.
There's also Tesla Traffic Incidents and Information but that's pretty finicky sometimes.
