Your right to repair
Since 31 July 2026 the EU right to repair applies (Directive (EU) 2024/1799). For devices of this type the manufacturer must repair on request, also after the legal guarantee has ended, at a reasonable price. The obligation lasts as long as EU rules require spare parts for the device.
If a defect appears during the legal guarantee and you choose repair instead of replacement, the guarantee is extended by twelve months.

Buying used?
Good as a used device Long updates, good repairability and a battery that lasts or can be replaced.
- Updates until at least 2035-10-22
- Battery replaceable, 1,000 cycles ≈ 2.5 years
- Spare parts until at least 2037-10-22
- EU class B: good
What to check: Ask about the battery: remaining capacity or charge cycles; below 80 % capacity a replacement is due. Check on the device when the last security update arrived and that account and network locks have been removed. Guide to buying used

How the used-device verdict is made
Four fixed rules from the supplier data in EPREL, as of 10 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.
