Samsung Galaxy S26 Ultra vs S25 Ultra: 5 expected upgrades worth watching
With the Galaxy S25 Ultra now available at a discount, buyers are wondering whether to upgrade now or wait for Samsung’s next flagship. And if early leaks are to be believed, the Galaxy S26 Ultra will definitely bring upgrades, focusing more on display efficiency, performance, and charging rather than a major redesign.
Samsung’s Ultra lineup has long set the benchmark for Android flagships, and with the Galaxy S26 Ultra expected to launch in early 2026, and the Galaxy S25 Ultra now available at a discount at both online and offline stores, many buyers are asking the same question: should they wait for the next-generation flagship, or go for the S25 Ultra right now?
The S25 Ultra is still a powerful device and, in fact, remains one of the most capable smartphones on the market today. That said, the Galaxy S26 Ultra will naturally come with upgrades. However, it is still too early to compare the two, as Samsung has kept everything under wraps. But if leaks and rumors are to be believed, Samsung’s next Ultra may focus more on refining the essentials rather than reinventing the wheel.
From display efficiency and camera changes to chipset upgrades and faster charging, rumors point to a lot of upgrades. Let’s take a closer look at what’s buzzing about the new generation of Galaxy phones and how the rumored Galaxy S26 Ultra might stack up against the Galaxy S25 Ultra.
Samsung Galaxy S26 Ultra vs S25 Ultra: Display
The Galaxy S25 Ultra comes with a 6.85-inch Dynamic AMOLED 2X display, which delivers top-tier brightness, sharpness and color accuracy. It’s already one of the best smartphone screens available today.
However, the S26 Ultra is rumored to take things a step further. Although it is expected to keep the same 6.9-inch Class display, it may switch to Samsung’s new M14 OLED panel. According to tipster Ice Universe, this panel is designed to be 20-30 percent more power-efficient than the M13 OLED used in the S25 Ultra.
So, while the leak suggests that you shouldn’t expect a dramatic visual overhaul, you can look forward to a smarter and more efficient display experience.
Samsung Galaxy S26 Ultra vs S25 Ultra: Chipset
The Galaxy S25 Ultra is powered by a Snapdragon 8 Elite processor, paired with 12GB of RAM, and runs One UI 7 based on Android 15. It delivers flagship-level performance for gaming, multitasking and photography – and still has plenty of life left in it.
However, for the S26 Ultra, Samsung is expected to raise the bar. The next-generation flagship is tipped to run on Qualcomm’s Snapdragon 8 Elite Gen 5, possibly in a custom “For Galaxy” edition. According to the leak shared by Ice Universe and echoed by other industry watchers, the chip could be built on a 2nm process, which will bring benefits in both performance and power efficiency.
There is also talk of a RAM upgrade, with the S26 Ultra offering 16GB of RAM as standard. If true, it would be a worthwhile step up from the S25 Ultra’s 12GB – especially for users who rely on heavy multitasking, AI features, and advanced photo processing.
Samsung Galaxy S26 Ultra vs S25 Ultra: Camera upgrade
In the photography department, the Galaxy S25 Ultra features a quad-camera setup with a 200MP main sensor, supported by a 50MP + 50MP lens and a 10MP telephoto camera. The system is reliable and delivers excellent results in most scenarios, especially in zoom and low-light photography.
For its next-generation flagship, Samsung is rumored to be improving this setup rather than completely changing it. The leak suggests that the Galaxy S26 Ultra may retain the 200MP main camera, but with a wider f/1.4 aperture, allowing more light in for better low-light shots. The telephoto setup is also expected to get an upgrade, with rumors pointing to improved 3x and 5x zoom lenses designed to deliver cleaner results at higher magnifications.
Samsung Galaxy S26 Ultra vs S25 Ultra: Battery and charging
The Galaxy S25 Ultra has a 5,000mAh battery, which should deliver good all-day performance, but charging speed has long been a hindrance. Samsung has stuck to 45W wired charging for generations, while rivals have gone much further.
This is where the Galaxy S26 Ultra may finally break tradition. According to Ice Universe, Samsung is testing 60W wired charging for its next Ultra flagship. Internal testing reportedly shows that the phone charges from 0 to 75 percent in about 30 minutes in laboratory conditions.
Battery capacity is also expected to see a slight bump, with leaks pointing to a range between 5,100mAh and 5,400mAh. If Samsung manages to combine a larger battery, more efficient display, and faster charging, it could easily be one of the most noticeable upgrades over the S25 Ultra.
Samsung Galaxy S26 Ultra vs S25 Ultra: Software and long-term support
The Galaxy S25 Ultra launches with One UI 7 based on Android 15, and Samsung continues to be the leader in the Android space when it comes to long-term software support.
The S26 Ultra is expected to launch with Android 16 and One UI 8, which will bring improvements to AI features, personalization, and productivity tools. While software alone may not make the upgrade, it will certainly make the new Ultra feel more future-ready.
Samsung Galaxy S26 Ultra launch date
Please note that these upgrades are based on leaks and rumors. As of now, it is still too early to make a final call between the two devices. The new generation Ultra will definitely bring an upgrade, but whether it’s worth the wait will depend on what Samsung ultimately introduces.
The Galaxy S26 Ultra is rumored to be launched around February 25 at Samsung’s next Unpacked event, which is expected to take place in San Francisco. Only then will Samsung finally reveal what its next flagship is actually capable of and give buyers a clear answer about whether to upgrade or get the S25 Ultra.
