So my condo apparently has very thick walls. Despite have a cell tower less than a km away, I'm still getting one bar. I figured no problem, flip on wifi calling and all is good. A few days later, I start to notice a battery drain issue. Fully charged usually lasted a full day, now I was barely getting half a day. I flipped wifi calling off and now back to normal.
This was the same with the S9 running latest update.
I think I may have to invest into a cellular repeater soon as I'd rather have more battery. Can anyone recommend one that didn't cost them 3 - 400?
I use wi-fi calling all the time while at home and there is no difference in battery usage.. I would check to see you you have any apps running in the background.
Have you checked the WI-FI calling feature in safe mode? If not, please perform the safe mode and check whether any third party apps causing the issue. Also, please uninstall any recent apps.
