Apple is adding a magnet to the back of the iPhone 12 to make it line up better with wireless chargers, for more efficient charging. This also enables certain accessories to snap on to the back of it, like a slim wallet the company showed off, and will allow wireless charging to work through some accessories.
I am excited that my 12-mini should be shipped this week. I bought a case for it and then compared that to my old i5 sitting in a desk drawer and my i7 I use for business calls. It comes in between the two, but without the reduced real-estate of the prior models, what some called the “chin” and “forehead” null portions of the screen. Very, very close in size to what was considered the best one-hand phone ever, the i5. And it has an eSim along with a physical sim I can have two phone #s on a single device. The young woman at the Verizon store seems very excited to see it when it comes in. And a recent review raved about having all the modern features in a very small package.
