Everything to expect from iPhone 17 lineup: new designs, larger batteries, and the debut of the iPhone 17 Air

Apple’s September 9 event will showcase the iPhone 17 family, with four models expected: iPhone 17, iPhone 17 Air, iPhone 17 Pro, and iPhone 17 Pro Max. Here’s a look at the major features and rumors leading into launch day.

iPhone 17 Air

The most talked-about addition is the iPhone 17 Air, which is set to replace the Plus model. It will measure 6.6 inches and emphasize a slimmer, lighter build. Its main drawback may be battery size, rumored at just over 3,100 mAh, the smallest of the lineup. The Air could ship without a SIM tray in most regions, relying entirely on eSIM. For China, however, regulatory filings hint at a SIM-equipped version to meet local requirements.

Battery Upgrades Across the Lineup

This year marks a significant focus on power. The iPhone 17 Pro Max is expected to feature a massive 5,088 mAh battery, the first time an iPhone surpasses the 5,000 mAh mark, potentially making it the longest-lasting iPhone ever. The Pro model is also getting a healthy boost, while the base iPhone 17 is expected to stay closer to its predecessor. Apple may be using advanced silicone-anode battery chemistry to deliver more efficiency, especially in thinner designs like the Air.

Pro Model Design Changes

The Pro and Pro Max could feature a new hybrid build: aluminum paired with a lower glass section to enhance wireless charging. To house the bigger battery, the Pro Max may be slightly thicker than its predecessor, though Apple’s switch from titanium to aluminum in some areas could keep weight steady or even lighter.

Colors and Accessories

New color options are expected, with the Pro models tipped to arrive in orange, dark blue, black, and white. Leaked cases have also revealed a new lanyard slot, allowing accessories like crossbody straps to attach magnetically.

Dynamic Island Speculation

Some rumors suggested the Dynamic Island might shrink from its current size, but reliable sources maintain it will remain unchanged for now. The feature’s future evolution could arrive in later models, but the iPhone 17 is likely to keep the familiar design.

The Bottom Line

Apple’s iPhone 17 lineup looks set to deliver meaningful improvements in battery life, durability, and design, while the iPhone 17 Air pushes Apple further into ultra-thin territory. With only hours to go before the event, these rumors will soon be confirmed.
