Soon all phones will have wireless charging and that in itself will provide a re-charge standard.
Although an accessory I bought the 27 watt fast charger for my Xiaomi phone. I just place it on a circular pad for super quick and convenient charging, and the pad is i-phone compatible and presumably any other wireless chargeable phone.
I guess there will still be a need for cable charging though, when in the car for example.
No need to worry about cables on the Plus 6 BTW once you have a self powered Bluetooth adaptor plugged into it, allowing wireless audio hookup.
