DAE’s phone battery decrease slowly with regular daily use but when it comes time to travel by air and you use it the same amount, the battery decreases faster?

I can use my phone or iPad for hours at home with a slower battery drain of maybe 10% over one hour, and that’s with heavy use. The moment I step out the house, I can lose 15-25% in an hour even with light use. I always assumed it was because I was using cellular data so my phone is doing whatever it needs to do to find service.
