Wireless charging works great, except that even the gentlest braking or acceleration seems to slide the phone off the hotspot. It’s an iPhone plus, so heavier than average, and I’m beginning to think I need to put some kind of backstop in the pad to keep it in place.

Anyone out there who’s already experienced and solved this issue? Is there a product that solves it, or a workaround?

 

Not sure where the coils are, but you could try rotating the phone 180 degrees

 

Perhaps a different case for your phone would help.
