find it hard to believe that a phone in standby mode
I don't have any rotten apples, but with Android (and I have no reason to think ios is any different), there's no such thing as "standby". All that happens is that the screen goes blank (either after time or by dating the power button). The device is still fully operational in all respects unless it is put into Flight Mode.
"My device comes on really quick from Standby" is a misnomer. All that is happening is that the screen is being turned on.
You've got to "slew the compass" in a CRJ? Ark version 2?
