My iPhone 7+ lasted almost 4 years of pretty heavy use. But it’s been having a hard time holding a charge, and it wasn’t hard for me to convince myself that $2,000 for a new phone is the same as $200 for a new battery. Maths is hard.
As usual, the camera improvements are the most obvious change in the new iPhone 12 Pro. Above is “realtor mode”, a wide angle that really enhances our long narrow living room. Below is a zoomed in closeup, definitely better resolution than before.
