Apple has managed to create the world's smallest 5G device, as the 5.4-inch "mini" model wasn't left out of the party after all. Experts were betting that the smaller device would be 4G-only, as its smaller battery wouldn't be able to handle the increased power draw required by the 5G connectivity technology, but Apple found a way to do it nonetheless.
In general, the iPhone 12 "mini" feels equally good as the higher models, at least in its own size terms. In fact, it misses none of the core features of the new lineup, featuring the A14 Bionic chip, the Ceramic Shield glass, IP68 water-resistance rating, a Super Retina XDR display, Face ID, Smart HDR 3, wireless charging, and 4K 60 fps video recording.
Cramming all that into a device that small in size is an impressive engineering feat, and it also appears that Apple has also found ways to help with heat dissipation, too, as 5G is only adding to the rising temperature. The aluminum chassis of the device certainly helps on that part.
The holder of the smallest 5G device title before today's launch was the Sony Xperia 5 II, which now looks like a behemoth compared to iPhone 12 mini's size. All that remains now is to see what endurance ratings the device will achieve on the first battery tests.
