Can't argue with that, but remember that they (still?) ask(ed) you to turn off your phone on planes for "security reasons"

 @nthp @monnier @SecureOwl Specifically, old-style analog phones on around 800 to 900 MHz could not be guaranteed not to interfere with DME positioning as a result of powerful nearby transmissions on the mirror IF frequency of the aircraft's DME receiver. |
@monnier @SecureOwl They originally asked for cell phones to be turned off for safety, not security. FAA wasn't 110% sure, that a cell phone wouldn't interfere with the aircraft's instrumentation.
These days, they ask you to put your phone in airplane mode, so it won't be screaming out for a cell tower it can't reach. Thus making it so your phone will have a charge on it, when you land.
