bluetooth signal issues with watch

I have noticed that i cant go to far from my phone without it disconnecting from the phone. i have my phone in my room and if i go downstairs, its already disconnected. My airpods still work even if i go all the way to the basement. I know my watch was able to still be connected to the phone even that far away as well. I have S2 and Xs Max and i know the vesion is way older on the watch but i know it was way better than this. just wondering if anyone seeing same thing? Rebooting both devices doesnt do anything.
