How much am I missing by still using XR? It’s been paid off for a couple years and unlocked with AT&T now, but starting to have issues where apps/sites load slower and outright freeze sometimes. I don’t really want to have another monthly installment, but don’t want to shell out $1000 up front either. Is there much change jumping to the 14 or 15, or should I hang on until this XR completely dies another 2+ years maybe? Also worth noting the trade value has gone lower and lower every year, and another 2 years I probably won’t get anything for the XR.
