After few days of testing and digging i found nothing wrong with WireGuard... it turned out that for some reason after using WireGuard, WiFi Calling and/or VoLTE started to go crazy and eat up battery.
After disabling both features and with WG in Damand mode (always on) and 8h battery dropped shocking 2% ...
now, you/I can dismiss that report or try to find why Wi-Fi Calling and VoLTE going crazy with wireguard enabled. It might be bug in iOS, bug in T-Mobile implementation, bug in CFNetwork, or vpn extension, who knows. If you have ideas about that let me know.
thanks all for listening.
