How the used-device verdict is made
Four fixed rules from the supplier data in EPREL, as of 2 November 2026; we do not test devices, and no retailer pays for the verdict. Remaining years of updates are the end of sales (the data date if EPREL has no end date) plus the promised years of updates, minus today. “Good as a used device” means EU class A or B, at least 3 years of updates left and a replaceable battery or at least 1,200 charge cycles. “Good with a fresh battery” means class A or B, at least 3 years of updates left, built-in battery with fewer than 1,200 cycles. “Only usable for a short time” means less than 2 years of updates left. All other devices count as “Limited suitability”. Years of updates and spare parts run from the end of sales (Regulations (EU) 2023/1669 and 2023/1670); we convert charge cycles into years at one full charge a day.
