This article brings into comparison iPhones that potential buyers may already have and the true successor — the smaller iPhone 12 Mini. Also, many people who update don’t need the latest, greatest. They just want something similar to their last phone but better and not too big. Do remember that you can mentally substitute the iPhone 12 for the iPhone 12 Mini during the discussion as they’re virtually identical except for size and the battery.

Altho I usually bring in the article, it’s simply too long and detail-filled to make that practical. Be prepared tho as the conclusions generally come out in favor of the iPhone 12 Mini which will be available for order November 6th.
