An iPhone 12 Mini locked to owner shows up a lot for a phone people called too small. It was the first mini of the 5G era, so it became the default gift for anyone who hated large phones. The giver signed in, enabled Find My, and handed over a finished Mini. The recipient never held the Apple Account. A later wipe exposes that gap.
The small battery is a distraction sellers use when the lock appears. They talk about charging twice a day as if endurance were the only risk. Find My is the risk. A 5.4-inch body that dies at 4 p.m. is still bound to the same server record as a Pro Max.
First 5G mini and why the battery story is a distraction
Apple put 5G into the smallest 2020 body and the cell suffered for it. Reviewers hammered endurance. Used buyers still want the size. That mix keeps locked Minis in search results: people sell them when they get tired of the charger, wipe them, and list the compact 5G pitch. A wipe never clears the account.
Screen size does not change the server bind. Anyone selling a mini-only bypass is guessing. The IMEI still has to leave the original account.
Gift setup is how most locked Minis start
The 12 Mini was a common birthday and graduation phone because it fit a small hand and still said 5G on the box. The person who paid often finished setup under their own Apple Account so the Mini would locate if it was lost on day one. Years later the recipient lists it as theirs. Apple still sees the giver.
Ask who bought it before you ask who used it. A holiday receipt with this serial beats a story about charging twice a day. If the giver can still open their account, that is the shortest path. If they cannot, you are in proof-of-purchase territory, not battery-repair territory.
What to do when the giver is gone
Ask the giver to remove the Mini in iCloud Find. If that person is you, recover the account. If they are gone, you need a receipt that lists this IMEI or serial. Apple explains the lock in HT201365. A store gift receipt that omits IMEI and serial is usually not enough.

We do not unlock it for you. Results vary. The standard 12 is iPhone 12 locked to owner. The later last-mini body is iPhone 13 Mini locked to owner.
