I was on a 15 hour road trip so that totally makes sense with orange being overheating. It’s an iPhone X which has been doing that lately with age.Should be covered in your user manual. From a BMW manual, blue indicates that it is charging. Orange indicates that the device isn't charging due to a foreign object in the tray or a problem like overheating/etc. The LED will turn off completely if it stops charging or the device's battery is full.
How fast it charges can be a function of the type of device.

To be fair, moving electricity wirelessly isn't viable on any platform as a main source of recharging. It should be used as a supplement but hardly as your main option. It will get there; beamforming using magnetic coils to charge within ~3ft will be the new standard with hopefully more promise.I have not been impressed with wireless charging on any devices -- seems like it's one of those technologies that is a cool idea but it has a lot of drawbacks (slow charging and overheating being common across the board). I used to wonder why Apple was so late to implement it but now I wonder why they adopted such an imperfect technology. Usually when they implement something half-baked its their own "too ambitious, too soon" technology, not an established open standard!
