As the second device ever in the iPhone mini series, the iPhone 13 mini is very similar to its predecessor. Both come in at the same 5.4-inch size, feature a dual camera lens set-up and a pretty similar design.
While the iPhone 13 mini has a more powerful processor, larger battery and slightly improved display, these are only incremental upgrades and most people will be more than happy with the performance of the 12 mini in comparison.
