I think Alan K noticed his cellphone getting warm & having a shortened battery life while on a flight. Has this happened more than once, over a period of time?
Maybe your cellphone had a software bug at one time? Verizon had a bug in an update, recently. They must have loaded a defective update into my phone last Sunday or Monday. For about three days, the text-to-speech in my droid, would replicate my speech with every possible idiom it discovered. For example, if I dictated a text, "The cat jumped into the hat," the phone would respond with:
The cat jumped in to the hat
The cat jumped in two the hat
The cat jumped in too the hat
The cat jumped in 2 the hat

It was this way for about 3 days before they fixed it.

I suggest that you Google the issue.

I can see how a cellphone might receive no signal in a cave, but not so much in an airplane. The problem with that premise is that there is no shortage of signal from cell towers near the horizon via the plane windows. It's just that there is so much interference from so many cell towers at the horizon that you can't usually get a very reliable connection due to all the interference from so many towers.

Perhaps your flight was not as long as in my example so you just didn't notice a larger than normal battery drain. As I had said, it was drained after a long flight. It was like 4 or 5 hours. Alternatively, perhaps you were sitting next to the window with the cell phone well below the window's signal aperture or you had it stashed where it was shielded from window RF... just postulating.

I don't think the cell phone searches with wide open power until and unless it "hears" a tower in the first place, because it has nothing to respond to.  I have been on long flights where I forgot to turn off my cell phone and I haven't found my battery to be significantly down by the time I discovered it had been on.
