It sometimes loses 15% within minutes. I'm rooted, stock JWR66Y with TWRP.

You answered your own question. When you turn airplane mode off the phone automatically searches for a carrier network to join that it can't find because you don't have one so it searches forever which will drain the battery quickly.
