There really is a simple answer to this madness. As I’ve stated before several times, Apple gadget life is soooo much better if you stay 1 year behind the curve.
Want a “new” phone? Buy it in August BEFORE the new iPhone becomes available. Then install the last version of that year’s iOS which will be stable, then DONT INSTALL the next version of iOS until the following August- just before the new one drops.
Benefits: Finished version of iOS the day you get your new phone and not having to desperately download update after update throughout the year hoping they’ll fix all the aggravating bugs.
Launch day iPhones are for the birds. So is launch day iOS.
