Apple iPhone 17 Series Launch in September: iPhone 17 Air, 5000mAh Battery in Pro Max & More Upgrades Expected

July 6, 2025: Apple fans, get ready! If all goes as per Apple’s usual launch cycle, the much-awaited iPhone 17 series could be unveiled this September 2025. And this time, we may see a surprising change — the popular ‘Plus’ model might be replaced with a slimmer and more stylish version, possibly named the iPhone 17 Air.

What’s New in the iPhone 17 Lineup?

As per recent leaks and speculations, Apple could introduce four models in the iPhone 17 series:

• iPhone 17
• iPhone 17 Pro
• iPhone 17 Pro Max
• iPhone 17 Air (likely replacing the Plus variant)

Now, while there’s no official confirmation from Apple yet, these details are coming from credible leak sources in the Apple ecosystem. If true, the “Air” branding could be Apple’s way of pushing a lighter and more premium-looking phone, much like the iPad Air and MacBook Air.

Biggest Ever Battery in an iPhone?

One of the most exciting rumours surrounds the iPhone 17 Pro Max, which might pack the biggest battery ever in an iPhone – a massive ~5,000mAh cell! This detail came from well-known leakster Instant Digital on Weibo, who compared the battery capacities of previous Pro Max models.

Here’s a quick look at how iPhone batteries have grown over the years:

• iPhone 11 Pro Max: 3,969mAh
• iPhone 12 Pro Max: 3,687mAh
• iPhone 13 Pro Max: 4,352mAh
• iPhone 14 Pro Max: 4,323mAh
• iPhone 15 Pro Max: 4,422mAh
• iPhone 16 Pro Max: 4,676mAh
• iPhone 17 Pro Max (rumoured): ~5,000mAh

That’s close to a 10% increase compared to the iPhone 16 Pro Max. However, as 9to5Mac rightly pointed out, higher battery capacity doesn’t always mean significantly longer battery life. Factors like display power consumption, chipset efficiency, and software optimisation play a major role too.

Expected Features of iPhone 17 Pro Max

Here’s what we can expect (based on leaks and early reports):

• Processor: Likely to be powered by Apple’s next-gen A19 Pro chipset
• Operating System: Will run on iOS 26, which was recently announced at WWDC on June 9. This version introduces the visually refined Liquid Glass UI.
• Display: Might retain the 6.9-inch size, similar to its predecessor
• Camera: Yearly upgrades are expected, with Apple focusing heavily on camera hardware and AI-based enhancements

While we wait for official updates, the buzz around the iPhone 17 series continues to grow. Apple seems to be focusing not just on performance but also on design refinement and battery improvements with this generation.
