iPhone 8 – Smart Repair Flip via Vinted Monitor

Electronics often fly under the radar on Vinted, especially listings marked “locked” or “not turning on.”
This iPhone 8 was one of those, priced at only £7 because the seller assumed it was activation-locked.
After a £10 battery replacement, the phone booted fine with 77% original battery health, instantly bumping its value to around £60 on resale platforms.
