The Pro's use of titanium makes it lighter and stronger than previous models of other metals.
Bob O'Donnell, head of TECHnalysis Research said the steady prices were a surprise.
"I think both Apple and the carriers recognize that with consumers feeling pressure on their budget and the lack of dramatic changes it’s getting harder to convince people to upgrade. Keeping prices stable should help with that," he said.
The iPhone 15 costs $799, the iPhone 15 Plus starts at $899 and the Pro series starts at $999. The Pro Max starts at $1,199, the same prices as last year for the same levels of storage. Last year, Apple offered a $1,099 iPhone Pro Max model with less memory.
Apple still relies on iPhone for more than half of its sales, but the global smartphone market has slumped from shipping 294.5 million total phones to 268 million in the second quarter. Apple's shipments declined the least of any major smartphone maker, dropping from 46.5 million phones to 45.3 million, according to data from Counterpoint Research.
