Ah I see, I can confirm that the bluetooth hardware is only connected to the first channel on the op6, so with wifi off the second antenna can also be turned off to save power without affecting bluetooth signal strength. > > > -- steev > -- Kind Regards, Caleb

Like the c630, the OnePlus 6 is also capable of using both antenna channels for 2.4 and 5ghz wifi, however unlike the c630 only the first channel is used for bluetooth.
