Introduction
Samsung continues to stretch the limits of innovation when it comes to smartphones, and this is certainly true of 2025. The Samsung Galaxy S25 Ultra and Galaxy Z Fold 6 can be considered two of the most powerful and premium devices globally. As expected, the Galaxy S25 Ultra offers a traditional smartphone design with cutting-edge specifications; conversely, the Galaxy Z Fold 6 revolutionises productivity and multitasking with its foldable form factor. Choosing between the two, however, cannot be easy, especially in a tech-savvy city like Dubai, where consumers demand only the best when it comes to performance and luxury. Here is an in-depth comparison of these two flagship devices.
Design and Size
The Samsung Galaxy S25 Ultra is premium as per Samsung's design language with sleek, durable life. The boxy aesthetic, well-refined aluminium frame and matte glass back that maximises fingerprint resistance are preserved in the design. The S Pen integration is still a hallmark feature with all the benefits that make it a good choice for people whose lives are beautiful but who enjoy precision and note-taking. Overall dimensions and weight are generally designed to allow single-handed operation, resulting in an excellently balanced feel.
The Galaxy Z Fold 6, on the other hand, brings foldable innovation a notch higher. Samsung made the device thinner and lighter as compared to the previous generation, and it becomes incredibly easier to hold. Once unfolded, the Z Fold 6 Ultra transforms into a roughly tablet-sized view, serving multitasking and entertainment purposes excellently. In addition, the hinge has been reengineered for improved durability, and it has an IPX8 water resistance rating to enhance its longevity.
Incredible Display Differences
Display is one of the most important features for the flagships, and Samsung has set a new standard with both these models. The display on the Galaxy S25 Ultra measures 6.8 inches diagonally and features a WQHD resolution with a Dynamic AMOLED 2X panel, an impressive 120Hz refresh rate, and the highest rated brightness levels reaching for the heavens in the Dubai sun for outdoor visibility. The screen is well guarded by Gorilla Glass Armour, rendering it very tough against scratches and drops.
While the Samsung Z Fold 6 has taken display adaptability to a whole new level—a 7.6-inch foldable AMOLED main screen with an additional 6.2-inch cover display, both with 120Hz refresh rates—Samsung has even improved the crease visibility. The vast real estate now occupies, because of the immense screen, is fabulous for productivity, content consumption, and all forms of immersive gaming.
Performance
The Galaxy S25 Ultra and the Galaxy Z Fold 6 are the ultimate dual SIM smartphones with nearly identical price ranges. Both smartphones come with either Samsung's Exynos 2500 or Snapdragon 8 Gen 4 chipset, promising the ultimate high-end experience. Whether it be playing video games, editing videos, or even multitasking on several apps at once, both the Galaxy S25 Ultra and Galaxy Z Fold 6 have no issue with them all.
For increased long-term aptitude, the S25 Ultra will repeat well because of its thermal management optimized. On the other hand, the Z Fold 6 Ultra performs steal on excellent split screening memories for most corporates juggling to balance several tasks at a time that require usability across multiple tasks. The foldable display has also been optimised for the multitasking feature, according to Samsung.
Camera
Since Samsung was increased to an ever-higher level in terms of mobile photography, both of these phones will serve this legacy excellently. The primary sensor of the Galaxy S25 Uni is 200MP, which also makes it the clearest in detail. The additional sensors include a 12MP ultra-wide camera, a 50MP periscope lens (5x optical zoom), and a 10MP telephoto lens (3x zoom). AI-based computational photography guarantees results better than those of normal cameras in low light as well as portraits.
The Z Fold 6 Ultra does not boast of an excited camera, but it boasts a willing 108MP primary sensor, a 12MP ultra-wide lens, and a 10MP telephoto sensor satisfying at 3x zoom. The inside selfie camera is hidden under the display so that users can enjoy uninterfered viewing. While she may prove superior to the Z Fold 6 in sheer photographic dominance, the S25 will not convince in terms of versatility.
Battery and Charging
There is no doubt that almost every user from Dubai wants to have a smartphone that lasts throughout the day, and here is the answer from Samsung. The Galaxy S25 Ultra packs a 5,500mAh battery, more than enough to maintain the impressive usage after optimising efficiency. The refuelling system is quite rapid and easy with 65W wired and 15W fast wireless charging.
The Z Fold 6 Ultra houses a 4,800 mAh battery, optimised according to the more massive display it has. The Z Fold may be slightly below the S25 Ultra, but still packs in power for all-day use thanks to the software optimization. Super Fast Charging 45W gets the battery back to full in no time, and the wireless and reverse wireless charging add a touch of convenience.
Audio Quality and Haptics
Both devices come with stereo speakers, which are tuned over an AKG available, with the sound getting up to a more immersive experience. The Galaxy S25 Ultra has Dolby Atmos support, so it gets cinema-like sound. The Z Fold 6 Ultra gets quad-speaker support, hence the richer-sounding experience.
Haptics play a major role in user experience. The S25 Ultra will thus provide refined vibration feedback with its fantastic interactions. The senior Z Fold 6 Ultra cannot be compared with it in this niche but has better mesmerising touch experiences.
