re: Why does my battery on my iPhone drains on long car trip??

My battery goes down quickly if I'm offshore/nearshore.

I don't know if it's true, but I've been told that the phone is constantly searching for a signal, which evidently is power draining.

If so, could be true with all that rural driving you're doing.

I've been putting mine in airplane mode when not in use down there.

Now I'll listen to folks more smart than me.
