From flagship powerhouses to foldable fashion statements and battery beasts, this month’s lineup offers something for every kind of user. Here’s a deep dive into the top five upcoming smartphones launching in September 2025.
1. Apple iPhone 17 Series

Apple’s annual fall event is always a headline-grabber, and this year’s iPhone 17 series is no exception. Scheduled to launch on September 9, the lineup is expected to include four models: iPhone 17, iPhone 17 Air, iPhone 17 Pro, and iPhone 17 Pro Max. The biggest shake-up is the rumored replacement of the “Plus” variant with the all-new iPhone 17 Air, which is said to be Apple’s thinnest and lightest iPhone ever.
The iPhone 17 Air is expected to feature a 5.5mm ultra-slim profile, a single 48MP rear camera, and a 24MP front camera. It will likely run on the A19 Pro chipset, paired with Apple’s custom 5G modem and vapor chamber cooling. The Pro models are tipped to include a redesigned camera island, anti-reflective glass, and support for 8K video recording. The Pro Max may push boundaries further with a telephoto lens offering up to 8x zoom and a battery exceeding 5,000mAh.
Apple is also rumored to be going eSIM-only across all models globally, signaling a bold shift in connectivity standards. With upgraded displays, improved thermal management, and deeper AI integration, the iPhone 17 series is poised to redefine premium smartphone expectations.
2. Samsung Galaxy S25 FE

Samsung is set to unveil the Galaxy S25 FE on September 5 at IFA Berlin, continuing its tradition of offering flagship-like features at a more accessible price point.

Under the hood, the device may be powered by the Exynos 2400 chipset, paired with up to 8GB of RAM and nearly 5,000mAh of battery capacity. The triple-camera setup is likely to include a 50MP primary sensor, a 12MP ultra-wide lens, and an 8MP telephoto camera with 3x optical zoom. The front camera could see an upgrade to 12MP, improving selfie and video call quality.
Available in five color options, the S25 FE is expected to launch at a competitive price, making it a strong contender in the upper mid-range segment. With Android 16 and One UI 8 onboard, users can expect a polished software experience enriched by Samsung’s latest Galaxy AI features.

All three devices are expected to feature a 7,000mAh battery, a standout spec that promises multi-day usage even for power users. The F31 Pro+ may be powered by the Snapdragon 7 Gen 3, while the F31 Pro and F31 are tipped to use the Dimensity 7300 and Dimensity 6300 chipsets, respectively. This tiered approach allows Oppo to cater to different price segments without compromising on battery life.
