The iPhone 12 Mini was Apple’s first attempt at a genuinely small modern phone, and it is now the cheapest way into that size. Only two Minis were ever made — this one and the 13 Mini — before Apple abandoned the format.
It packs a full-size iPhone experience into a 5.4-inch body: edge-to-edge OLED, Face ID, dual cameras and 5G. What it does not pack is much battery, and that was the criticism at launch. Five years of charge cycles have not helped.
If you want the size cheaply and are prepared to replace the battery, it works. If you are not, look at the 13 Mini.

Discontinued model and discontinued size. Confirm availability, condition and battery health before planning around it.
Compare by network
Network options
Networks do not carry five-year-old discontinued models on standard contracts. The realistic routes:
Pre-owned handset plus SIM-only. Buy the Mini separately and pair it with a flexible plan. On a handset this age, avoiding a 24-month commitment is sensible.
Certified pre-owned ranges. Occasionally carry older Minis. Check warranty and battery health.
Whichever route, verify the handset is unlocked, the IMEI is not blacklisted, and — above all — that the battery has been tested or replaced.
Compare by budget
Budget options
Cheapest small modern iPhone. The core argument. Only two Minis exist, and this is the cheaper.
Budget for a battery. On a 2020 Mini, treat a replacement as part of the purchase price rather than a possibility. It roughly doubles the phone’s usability.
Compare against the 13 Mini. One generation newer, better battery and chip, more support life remaining, same size. Usually worth the difference. See iPhone 13 Mini contract deals.
Compare against the iPhone SE. Available new, cheaper, small — but a bezelled LCD, Touch ID and one camera. See iPhone SE contract deals.
Compare against a current standard iPhone. Larger, but new with a full battery and years of support. If small is a preference rather than a requirement, this usually wins.
Current and older alternatives
Alternative models
iPhone 13 Mini. The only newer Mini, and the last one. Better battery and chip. See iPhone 13 Mini contract deals.
iPhone SE. Small and available new. See iPhone SE contract deals.
iPhone 12. The standard model of the same generation — larger body, much better battery. See iPhone 12 contract deals.
Samsung S23. A compact Android flagship, if the platform is open. See Samsung S23 contract deals.
Between the two Minis, the 13 is the better phone in every respect that matters. The 12 Mini’s argument is price alone — which is a real argument, provided you fix the battery.
What to check before applying
- Battery health percentage, in writing — non-negotiable on this model.
- Whether the battery has been replaced, and when.
- iOS support status — confirm it still receives updates.
- Storage capacity — 64GB versions exist and fill quickly; not expandable.
- Network lock and blacklist status on a private purchase.
- Face ID and both cameras tested.
- Total cost of handset plus plan, including a likely battery replacement.
- Whether a month-to-month plan suits better than a long contract.
Any plan is subject to the provider’s checks — identification, proof of address, banking details, RICA registration, and possibly a credit and affordability assessment. Approval is not guaranteed.
FAQs
Is the iPhone 12 Mini battery really that bad?
It was the model’s main criticism at launch, and capacity degrades with age. On a 2020 unit expect noticeably short life unless the battery has been replaced. A replacement makes a substantial difference.
Should I get the 12 Mini or the 13 Mini?
The 13 Mini, if you can stretch to it — better battery, newer chip, more remaining support, same size. The 12 Mini’s advantage is purely price.
Is the Mini too small?
It is considerably smaller than any current iPhone. That is the point for some buyers and a dealbreaker for others. Handle one before committing, particularly if you read or watch video.
Does the 12 Mini support 5G?
Yes. The iPhone 12 generation was Apple’s first with 5G, and the Mini is included.
Will it still get iOS updates?
The iPhone 12 generation is well into Apple’s support window. Confirm the current position on Apple’s compatibility list before buying.
Is 64GB enough?
Not comfortably. iOS and apps consume a large share, and storage cannot be expanded. Prefer 128GB if you have the choice.
Is a Mini harder to type on?
Noticeably, if you have used a larger phone. The keyboard is narrower and the on-screen targets are smaller. Most people adapt within a week, but if you type a lot it is worth handling one first.
What does a repair cost?
Screen repairs on a Mini are not cheaper than on a standard iPhone despite the smaller panel, and on a 2020 handset the cost can approach what the phone is worth. Factor that into whether insurance makes sense.
Will a case make it too bulky?
A slim case keeps the size advantage; a rugged one largely negates it. If you bought the Mini for pocketability, choose the case accordingly.
