Should I buy a used iPhone 12 mini or a new iPhone SE 4?

For most people, the new iPhone SE 4 is the better buy — if it’s available in your market and priced reasonably. A new phone gives you a fresh battery, warranty support, and a much lower risk of hidden wear than a used iPhone 12 mini.

Choose the used iPhone 12 mini only if you really want the smallest, most pocketable iPhone-style design and you’re okay with older hardware and a battery that may already be worn down. The 12 mini is genuinely compact, with a 5.4-inch edge-to-edge display in a tiny body, but used units can have noticeably reduced battery life.

My simple recommendation:

1. Pick the SE 4 if you want the safer, longer-lasting purchase.
2. Pick the 12 mini if size is the top priority and you can inspect battery health carefully.

Because exact specs, availability, and pricing can vary by region, it’s worth checking the current official listing before buying.
