DJI FAQ: Turn off cellular and BT (and wifi?) on phone when flying???

[RetiredInFL]

Is it really necessary to turn everything off when flying. According to DJI 2S FAQ:

How can I improve the signal receiving quality of the DJI Air 2S remote controller?​

The remote controller antennas are built into the mobile phone holder. Please adjust the antenna direction according to the position of the aircraft. For more information about antenna directions, please refer to the User Manual.
In addition, do not wear any wearable devices with information transmission function during flight, and ensure that the mobile phone wireless network and Bluetooth are turned off to avoid interference with the aircraft's image transmission signal.

It’s not necessary but it can be helpful in high interference areas. I pretty much never do though.

I use Hotspot to get the maps loaded then switch the iPhone to airplane mode. If I have people with me I ask them to do the same. All part of the preflight checklist. Why take unnecessary chances, I’m not going to answer the phone when operating the drone anyway.

I generally go into airplane mode. It certainly doesn't hurt as far as interference goes and I don't really want to be receiving any phone calls while I'm flying.

Not UNIQUE to Air2S. Most of DJI's drones that use a RC - Mini 1&2, Air 1 & 2, etc.

Always. I turn off Bluetooth / WiFi / and put into Aeroplane Mode before takeoff.? Additionally I either don’t wear my Apple Watch or leave it in the car. Never had an issue.
