Processor and RAM are printed on the listing and almost never the thing that fails. Battery wear, thermals, hinges and a locked BIOS are — and all four are checkable in fifteen minutes.

The one number that decides whether a used phone is a bargain or a daily annoyance — how to read it yourself where the phone supports it, where the real cut-offs are, and the three ways it gets faked.

Thirty seconds, free, and it is the only check that can save you the whole phone. How to read an IMEI off a handset and verify it against the Government CEIR database.
