As we move into mid-2025, anticipation is growing for Apple’s next big release: the iPhone 17 series, slated for a September launch. Tech enthusiasts and casual users alike are buzzing with excitement over rumors of a transformative lineup that includes a brand-new model, the iPhone 17 Air, alongside the iPhone 17, iPhone 17 Pro, and iPhone 17 Pro Max. From a sleek, ultra-thin design to cutting-edge camera technology, enhanced connectivity, and powerful new chips, the iPhone 17 series could redefine what we expect from smartphones. While Apple has yet to confirm these details, leaks and analyst insights provide a compelling glimpse into what’s coming. Here are the 10 biggest upgrades rumored for the iPhone 17 series, based on the latest information as of May 2025.
1. iPhone 17 Air: Apple’s Thinnest iPhone Yet
The iPhone 17 Air is poised to steal the spotlight as Apple’s slimmest iPhone ever, with a rumored thickness of just 5.5mm at its thinnest point, though the camera bump may increase this to 9.5mm (MacRumors iPhone 17 Air Features). Featuring a 6.6-inch OLED display with Face ID and a Dynamic Island, this model is expected to replace the less popular iPhone Plus variant, offering a lightweight, elegant alternative that balances portability with a large screen. Unlike the Pro models, it may feature a single rear camera, emphasizing design over advanced photography capabilities.
2. 120Hz ProMotion Displays Across All Models
Apple is reportedly bringing 120Hz ProMotion displays to every iPhone 17 model, a feature previously reserved for Pro variants (MacRumors iPhone 17 Roundup). This upgrade promises smoother scrolling, more responsive touch interactions, and enhanced visuals for gaming and animations. The use of LTPO OLED panels could also enable an always-on display, though it’s uncertain whether non-Pro models will include this feature. This move ensures that all users, regardless of the model they choose, enjoy a premium display experience.
3. A19 Chip: Next-Level Performance
The iPhone 17 series is expected to be powered by Apple’s A19 chip, with the Pro models potentially featuring a more advanced A19 Pro variant (MacRumors iPhone 17 Roundup). Built on an upgraded 3nm process (TSMC’s N3P), these chips are designed to deliver superior performance and energy efficiency compared to the A18 chip in the iPhone 16 series. Expect faster app launches, seamless multitasking, and improved battery life, making the iPhone 17 series ideal for demanding tasks like gaming, video editing, and AI-driven applications.
4. Advanced Camera Systems
Photography is set to get a major boost in the iPhone 17 series. The iPhone 17 Pro Max is rumored to feature a 48-megapixel telephoto lens, a significant upgrade from the current 12-megapixel version, promising sharper zoomed-in shots (MacRumors iPhone 17 Pro Features). All models may include a 24-megapixel front camera with a six-element lens for improved selfies and video calls. Even the iPhone 17 Air is expected to sport a 48-megapixel rear camera, ensuring high-quality photography across the lineup, despite its single-lens design.
5. Apple’s In-House 5G Modem Debut
The iPhone 17 Air is likely to introduce Apple’s first in-house 5G modem, marking a shift away from Qualcomm’s chips (AppleInsider iPhone 17 Air Rumors). While it may not support mmWave 5G initially, the modem is expected to deliver download speeds of up to 4Gbps, offering reliable connectivity. This move enhances Apple’s control over its hardware, potentially leading to better integration and efficiency in future models.
6. Enhanced Connectivity with Wi-Fi 7 and Bluetooth 5.3
All iPhone 17 models are rumored to support Wi-Fi 7, which offers faster internet speeds, lower latency, and improved performance in crowded networks (MacRumors iPhone 17 Roundup). Bluetooth 5.3 is also expected, enhancing connectivity with accessories like AirPods and smart home devices. These upgrades ensure the iPhone 17 series is future-proofed for the latest wireless standards, providing a seamless online experience.
7. Durable, Anti-Glare Displays
Apple may equip the iPhone 17 series with a new anti-reflective display coating to reduce glare and improve visibility in bright sunlight (MacRumors iPhone 17 Pro Features). However, earlier rumors of a super scratch-resistant coating have been contradicted, suggesting this feature may not materialize (MacRumors iPhone 17 Pro Features). The displays are still expected to offer enhanced durability, protecting against scratches and minor drops.
8. Simplified Battery Replacement
Apple is reportedly continuing its efforts to make battery replacements easier, using new adhesive techniques introduced with the iPhone 16 series (MacRumors iPhone 17 Roundup). This change could lower repair costs and make the process more accessible for users and third-party repair shops, promoting sustainability by extending the lifespan of the devices.
9. Redesigned Camera Bump
The iPhone 17 series may feature a redesigned camera bump, with Pro models sporting a large rectangular bump with rounded corners and a triangular lens arrangement (MacRumors iPhone 17 Pro Features). The iPhone 17 Air might have a unique horizontal camera bar for its single rear camera (MacRumors 17 Reasons to Wait). These changes aim to enhance aesthetics and accommodate advanced camera systems.
10. eSIM-Only Expansion
Apple may expand its eSIM-only approach to more regions, following the removal of the physical SIM tray in the US with the iPhone 14 series (MacRumors iPhone 17 Roundup). The iPhone 17 Air’s ultra-thin design makes it a prime candidate for this shift, though it’s unclear if markets like India will adopt eSIM-only models. This change could streamline design but may require users to adapt to eSIM technology.
