Samsung is set to unveil two of its most anticipated flagship smartphones later this year, the Galaxy Z Fold 7 and the Galaxy S25 Ultra. While both cater to high-end users, they serve distinct purposes: the Fold 7 highlights cutting-edge foldable tech, while the S25 Ultra builds on traditional smartphone strengths like performance and camera excellence. The Galaxy S25 Ultra will maintain its classic bar-style design and is expected to weigh around 218 grams. It’s rumored to feature a 6.9-inch flat AMOLED display, a titanium frame, and retain its signature angular design with a built-in S Pen, continuing the legacy of the Galaxy Note lineup, according to Phone Arena. In contrast, the Galaxy Z Fold 7 is expected to sport a slimmer profile than its predecessors. When folded, it may match the S25 Ultra's thickness at 8.2mm but weigh a bit more, around 236 grams, due to its hinge. The outer display is likely to be wider, with the main foldable screen measuring up to 8 inches, per the same source.
The S25 Ultra is expected to come with Gorilla Armor glass and a full IP68 water and dust resistance rating. Meanwhile, the Z Fold 7 may only achieve IP48, indicating lower dust protection due to its foldable structure.
Display
Both models are anticipated to feature Dynamic AMOLED 2X panels with 120Hz adaptive refresh rates and peak brightness exceeding 2,800 nits. The S25 Ultra will likely offer a single high-resolution QHD+ display. The Z Fold 7, however, will offer a dual-screen experience: a 6.5-inch outer display and a larger inner foldable screen.
Performance and Software
Under the hood, both devices are expected to run on the Snapdragon 8 Gen 3 for Galaxy chipset built on the 3nm process. Each model should offer a minimum of 12GB RAM, with the Z Fold 7 possibly getting a 16GB variant.
They’re expected to launch with Android 16 and One UI 8, featuring Samsung’s latest Galaxy AI tools such as live translation, call summaries, and Circle to Search. Both phones are also projected to receive seven years of software updates.
Camera
The Galaxy S25 Ultra is likely to retain its powerful quad-camera system: a 200MP main sensor, a 12MP ultra-wide lens, a 10MP 3x telephoto lens, and a 50MP periscope lens offering 5x optical zoom, maintaining its status as Samsung’s camera flagship.
The Z Fold 7 is also tipped for a significant camera upgrade, possibly adopting the same 200MP main sensor. However, the rest of its setup may remain modest, potentially including a 12MP ultra-wide and a 10MP 3x telephoto lens. Unlike the Ultra, it may not feature extended zoom capabilities.
Battery and Charging
The Galaxy S25 Ultra is expected to pack a 5,000mAh battery with support for 45W wired and 15W wireless charging. The Z Fold 7 is likely to retain the 4,400mAh battery from its predecessor, along with 25W wired and 15W wireless charging.
Final Thoughts
The Galaxy S25 Ultra is ideal for users seeking top-tier camera performance, long battery life, and stylus functionality. Meanwhile, the Z Fold 7 caters to power users looking for a multitasking powerhouse in a foldable design, potentially with better portability and improved camera features. Samsung has yet to confirm official launch dates and complete specs.
