Why does even Airplane Mode exist?

Few days ago I was flying by plane and stewards asked us to turn our devices to Airplane Mode. But why is that?

It used to be a cellphone could actually cause errors in the flight equipment. It doesn’t anymore, but there’s two other reasons, why you‘re still asked to do so:

1. a cell phone that has lost its signal will keep searching for it. Its using a lot more energy and a lot more electromagnetism than when it is actually connected. With a whole lot of cellphones in one plane, that would really add up.

2. So people don’t make calls. Can you imagine 200 people in a metal tube calling home at the same time? It would incredibly loud, everyone trying to be audible.
