Owner/repair thread on iFixit describing a specific hardware panic signature.
What to check. A 14 Plus stuck in a 3-minute reboot loop may be a charging-port flex/back-glass sensor hardware fault, not a dead battery — a battery swap may not fix it. Get a proper panic-log diagnosis before paying for parts.

What to check. A Turkish owner reports unusually fast battery-health loss (95% in 7 months) despite original charger and not charging while in use. Warranty battery claims may be contested by Apple, so check coverage early.

Kriko reads a listing and tells you which of these apply to that exact product. It runs on your computer, needs no account and is free.
These reports come from the pages linked under each item: owner forums, repair guides and workshops. They are not a diagnosis of any one unit, and a careful check of the one you are buying still applies.
