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.
 
Charger is permanently on as far as I'm aware.

The simplest way round it would be to put your phone in either the glovebox or centre armrest, charging it via USB if required.
 
Change phones :D

Sorry I can’t help further.

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.

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.

I do not understand why this should be so, if it is not sitting on the charging pad correctly then clearly it will not charge, the 'phone discharge rate is not influenced by the charging pad not operating.
 
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.
 
The charging symbol shows on the media screen and my phone beeps to indicate wireless charging is active but when you retrieve the phone the battery has actually gone down!

I was hoping that there was a hidden system menu to disable the charging pad. its handy having the phone in there. I'll just keep it in the centre console and USB charge it if required.

Thanks for the replies folks. Appreciate your time.

Plug it in under the arm rest then. You’re not going to be looking at it while driving, so surely there’s no need to have it in the centre console

You have to remember that so many people nowadays are lost if they don't have their mobile phone either in their hand or in a position that they can see it! Absolutely pathetic! More important matters in the world. If a call is really really really important then there is a good chance that the caller will try again.
 
Thanks again folks. Some people seem, however, to have missed the actual question.

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.

Thank you for this explanation - very informative.
