PP never claimed that the airlines/FAA have this "rule" to save battery life. They were merely responding to the inaccurate claim by PP that turning on airplane mode serves no purpose. The two are different issues, both are being discussed in this thread. |
| Some people get power trips from breaking rules. Whatever turns their crank. |
But a lot of rules are only sporadically enforced; that doesn't mean you shouldn't follow them. The odds of being caught cheating on your taxes are pretty low, but I still try to make sure my returns are accurate. This airplane rule obviously has virtually nonexistent stakes, so it's not the same thing, but I don't really see the point of deliberately not doing something the airlines and the government have indicated they expect you to do — when it takes no effort and comes with no cost — just because you've decided you know better. |
| I always turn everything either off or to Airplane Mode. EMI is a real issue for avionics. Maybe a small few devices accidentally left on will not cause issues in a modern airplane, but a plane full of people with all their devices on certainly can. |
| I always switch my phone to airplane mode and pester my teenage daughters to do the same. Once I forgot and we were in some significant turbulence- flight crew strapped in, the plane kept doing those stomach lurching drops and was even shuddering. My daughters’s phone suddenly started blasting a super loud amber alert and someone started yelling “ Oh my god it’s a warning! It’s a warning!” I had to yell out it was a cell phone amber alert and all I could hear behind me was “ it’s ok it’s ok it’s ok we’ll all be ok.” |
Today’s installment of things that didn’t happen. |

I doubt that anything would happen to a plane if I left my phone on, but I still turn out it in airplane mode. Why tempt it and it does save battery.
What worries me more than whether phones are in airplane mode, is people checking suitcases with lithium-ion batteries. I don’t know if everyone knows about this danger and the warning/inquiry when you check your bag isn’t the most effective- often it’s communicated in very broken English. |
