Do you mean it is draining the vehicle battery? I would find that hard to understand as the wireless charging mat is only powered with ignition on, according to the manual. If it is the phone battery draining then I don't see how that could be caused by the wireless charging function either.Hi,
does anyone know if it is possible to deactivate wireless charging? My note 9 is too large to sit properly on the very small charging pad and due to the poor contact it is draining my battery.
Any help appreciated.
Due to the phone being too large to sit completely flat on the pad it is causing the phones battery to drain. Lost 6% in 10 mins.Do you mean it is draining the vehicle battery?

The manual does mention that, when on the charging pad, the phone uses the car external aerial. It must couple with it in some way, as there is no physical connection, so perhaps when it is close - but not close enough - this leads to a higher power consumption. Perhaps one solution to the original problem would be to put the phone somewhere else, as it is not charging anyway.
For the external antenna the car has an antenna coupler. Nothing exotic, couplers were used already with the old style UHI-cradles when phones started to abandon the physical antenna port. Using the external antenna should reduce power consumption, lower transmission power needed. Obviously if the phone is too far from the coupler, it could not make use of the coupler and theoretically consumes a bit more power because the "hidden" position. I doubt the issue here is about the antenna efficiency and transmitter power consumption though.
If the phone really consumes more power at the charging pad, it could be because of higher phone activity which the poorly working wireless charger does not compensate (because of distance). I would first check which applications resume from the power saving state when the phone is connected to a charger. Charging control itself must take some additional power, odd if it would be significant.
