Repair-or-replace calculators for the moment a device starts failing. A browser cannot read your hardware directly, so these do the arithmetic on figures you read from your own system report — battery capacity, for instance — and turn them into a clear health percentage. The result is the evidence for whether a repair is worth it, framed around fixing first and replacing only when the numbers say so.
