Apple is expected to unveil the iPhone 16 Monday. Although the new phone will probably get a few small upgrades on the outside, Apple is betting that significant changes to what’s on the inside will excite customers who haven’t been given a convincing reason to upgrade in years.

To get the full trade-in value, you'll need to relinquish an iPhone 15 Pro Max, but you can still save a few bucks if you're swapping an aging iPhone for the iPhone 16.

Apple launched its latest entry into the smartphone market and major upgrades in its wearables at the "It's Glowtime" event Monday.
