Phone app draining battey

Hey guys, I have noticed lately my S6 edge is draining the battery fast . When i check battery usage, the phone app is at 25-30% usage. Thanks if anyone has any insight to share.

If you have WiFi calling enabled you might want to turn it off.

WiFi calling is off. I turned it off and back on and so far today it seems to be working normal.System idle is the top usage and the phone app isn't even on the list.
