Definitely not normal. Have you tried doing a phone restore? Worse come to worse restore and set it up as a new phone.

Mine if still at 100% before I sleep, 6 hrs later will still be at 100% or at most drop 1 or 2% at most.

I suggest you have it on Airplane Mode before you sleep. It might help

Mine doesn’t have such issue also, maybe SIM card is the one draining battery. probably you should try to take out SIM card to try.

I remember there was a suggested solution posted by Apple themselves, which requires affected users to do a full restore. I went to look for the webpage for reference but can’t find it anymore.
