Will this get better when wifi is enabled?
No, we’ve been connecting to the Model S with the phone app since 2012. This is different from using it as a key. Sometimes it takes longer to wake up. The Model S and X have an “always connected” option which can speed up the process, at the expense of slightly higher vampire drain. The Model 3 does not have this check box— I don’t know if that means always connected is on for everyone, or off for everyone.The problem is you were trying to use your phone as a car key. Phones weren't meant for that.
