The increase could eventually force Apple to raise iPhone prices, though the company may absorb some of the additional cost to avoid putting too much pressure on demand.

Apple is expected to unveil the iPhone 18 Pro, iPhone 18 Pro Max and its first foldable iPhone Ultra next month, so we don’t have long to find out whether those higher production costs ultimately reach consumers.
