How Accurate Are These Tools?
They give estimates, not a diagnosis. Charging time depends on your cable, case, temperature and what you’re doing while charging. Repair prices vary by country and shop. For an exact answer, your iPhone’s own Settings and Apple Support are the final word. If your iPhone shows a service message, contact Apple Support.
