For anyone reading this thread from the U.K. and feeling that they’re missing out because the wireless charger wasn’t available in the U.K. (or trying to get it retro-fitted), you’re missing nothing.
I got an Irish T6.1 California where the wireless charger was an option. I paid a small fortune for it (more than €500 IIRC) thinking that, together with wireless Apple CarPlay, it would be the perfect combination.
The wireless charger just doesn’t work. On top of this, having it fitted means that this storage compartment is now unusable and a waste of space.
I really wish I hadn’t wasted my money on this.
It’s not an issue specific to the California or even VW. Wireless chargers in cars often don’t really work. For a wireless charger to work well, the charging coils in the charger and in the phone must be perfectly aligned. If they’re misaligned, charging will be very slow and the device will over-heat. If too far apart, the device won’t charge at all. That’s why Apple came up with the magnetic MagSafe system to ensure that the phone is always placed in exactly the right spot.
With the type of wireless charger typically found in a car where you slide your phone into the charger, your phone will almost never be correctly aligned - unless you’re incredibly lucky, have a phone of exactly the right size and shape, place it in exactly the right spot and have a phone that’s thick enough to stop it from sliding around in the charger.
In practice, we’ve tried with multiple different models of iPhone from the 8 to the 13 Pro and none of them worked. At best, we were able to get a trickle charge of about 1% per hour until the phone got so hot it shut itself down as a safety measure.
Most of the time, it just doesn’t charge at all. Or charges for a minute or two and stops. Absolute garbage.
