I've had my iPhone XS Max since launch day and lately, I've been noticing that the Bluetooth range is getting worse and worse. If I walk away from my iPhone and enter another room in my house, my Apple Watch falls out of range and disconnects. I was at my fiancé's parents house last night and walked away from it in the same room and it showed the phone disconnected symbol on the watch face when I checked the time. I also noticed that if I leave my phone in my coat pocket while driving in my car, the music being streamed from it to the car via Bluetooth will start to skip and break up until I take it out of my coat pocket and put it out in the open in the center console. I'm not sure if this is a hardware or software problem at this point but figured I'd start here before calling Apple to see if it's something I can fix on my own first.
