The upcoming iPhone 15 Pro is expected to be priced higher than its predecessor by $100, and Apple Inc. (AAPL  ) could justify this increase by using space-grade titanium and stacked battery technology.

What Happened: Apple is reportedly planning on using space-grade titanium and stacked battery technology on the upcoming iPhone 15 Pro line-up, which could push the price by $100.

A leaker, @URedditor posted a design image of the iPhone 15 Pro on Twitter and also revealed that the iPhone 15 Pro and the iPhone 15 Pro could feature a titanium alloy frame.

Apple has reportedly been testing various titanium alloy mixes over the past year to find one that offers a combination of strength, durability, and radio frequency performance. The company has reportedly finalized a Ti-6Al-4V titanium alloy, which is an aerospace-grade material.

Stacked Battery: Another significant improvement that Apple is expected to offer is the increased battery capacity. The iPhone 15 series is expected to offer an increase of up to 20% in capacity.

Despite a significant increase in battery capacity, the iPhone 15 series is expected to retain its thickness, thanks to the stacked battery technology used in electric cars.

Stacked batteries have a denser configuration than regular batteries, allowing for a higher capacity without an increase in size.

A recent report suggested that the iPhone 15 Pro will start at $1,099 and the iPhone 15 Pro Max at $1,199, an increase of $100 each.

Apple is expected to launch the iPhone 15 series in September 2023.
