Serious call drops on iPhone XR

[Ucshade]

Several times I dial different numbers I get call failed almost on all attempts even some calls that are established will just drop on its own after few seconds of interaction, my phone still runs on iOS 15.4.1 and I must say this is frustrating, but I don’t know if someone is experiencing this or if it’s limited to most iPhone XR or a bug on its own

I don't experience this on my Xr. I am running 15.6 on it.

Maybe I’ll try 15.6 on it but then how is your battery life / performance

Battery life has been the same as previous updates. I wonder if your issue is carrier related.
