General 5G NR NSA cuts out below 30% SOC

[mattodinaturas]

Hi! I noticed a strange behaviour with my xiaomi 12 pro. When the state of charge goes below 30%, the phone refuses to connect to the 5G NSA network (unless the charging cable is connected). It just shows the 5g icon although it's not connected anymore
Has anybody else noticed this behaviour? I have tried disabling the "5g battery saving" option and setting "performance" in the battery menu but still no luck
My carrier is TIM IT. Thanks!
