Apple is gearing up to release the iPhone 17 Pro Max, expected to launch in the second week of September 2025. Recent leaks reveal a combination of design changes and under-the-hood improvements, making it one of the biggest year-over-year upgrades in the Pro Max line.
From battery life to camera enhancements, this device is shaping up to be Apple’s most capable iPhone to date.
Larger Battery and Slightly Thicker Body
The upcoming Pro Max model will feature a thicker design (about 8.725mm compared to 8.25mm in the iPhone 16 Pro Max), allowing for a larger battery, rumored to be close to 5,000mAh. That’s around 300mAh more than its predecessor and could result in 35 hours or more of video playback, up from 33 hours.
Cooling, Performance, and Camera Advancements
Apple may also introduce vapor chamber cooling in the Pro Max for better thermal efficiency during intensive use. This upgrade, paired with a next-gen chip, could improve sustained performance, especially for gaming and creative tasks.
Camera upgrades are another highlight. The phone is expected to include:
- Three 48MP rear lenses
- A 24MP front camera (up from 12MP)
- Improved low-light performance and software-driven clarity
Meanwhile, earlier rumors about a redesigned Dynamic Island have now been downplayed, with Apple expected to stick to the current design across models.
