Rene, a bold move. A thing I learned experimenting in my garage lab with inductive charging is the shape of the wave form and the way the pulse is timed over a duty cycle. I am no battery expert, just some guy, but this solves many temperature gradient issues I have come across.

Rene, Thus with 3 inductive coils, one can sequence the pulses in a pattern that adjusts to the type of device on the coils. The wave form should also be shaped over the cycle and also for each type of battery that is charged. You can not have 3 coils active at the same interval.

AirPower didn't just have three coils, it had 21 to 24, and many of them had to overlap three-coiled chargers exist and work fine; the thing Apple tried to do was eliminate dead zones where no power was available

Replying to @UlurooSpeaks @marcoarment and
Did they try three coils but moveable? iOS devices would report their precise location to AirPower and the coils would adjust. If coil separation is required, show a message to slightly nudge a device away from the others. The coils re-adjust. They own the full stack!

Constantino, yes! This is the Apple-like solution. Precisely the point I am making too.
