Comparing Galaxy S26 Ultra vs Galaxy S25 Ultra: Is there enough difference?

Place the Galaxy S26 Ultra next to the Galaxy S25 Ultra to clearly see the upgrades in AI, privacy screen, camera and fast charging on the new generation flagship.

After the Galaxy Unpacked 2026 event, Samsung officially launched the Galaxy S26 Ultra, the successor to the already very successful Galaxy S25 Ultra in the high-end flagship segment.

Instead of “transforming” changes, the new generation focuses on perfecting the experience with smarter AI, better optimized cameras and a few practical improvements in daily use. So when put on the scale, is the Galaxy S26 Ultra really superior to its predecessor?

The design is familiar but refined for more comfortable use

Overall, the Galaxy S26 Ultra still retains the typical design language of the Ultra series with a flat screen, square frame and camera cluster placed at an angle.

However, Samsung changed the way the back is finished by switching to a monolithic camera cluster design instead of the “floating ring” style on the Galaxy S25 Ultra, making the overall look more modern and uniform.

One controversial change is the switch from Titanium frames to Armor Aluminum. Although the new material may not feel as premium as titanium, in return the device is significantly lighter and thinner.

With a thickness of only about 7.9mm and weight of 214g, the Galaxy S26 Ultra feels more comfortable to hold when used for a long time, especially for those who often use the device without a case.

The screen is similar but has an additional “privacy shield”

Both devices have a 6.9-inch Dynamic AMOLED 2X screen, QHD + resolution, adaptive scanning frequency of 1–120Hz and maximum brightness of about 2,600 nits. The display experience is therefore almost equivalent: sharp, vibrant colors and easy to see outdoors.

The notable difference lies in the Display Privacy technology on the Galaxy S26 Ultra. This is an anti-peeping feature integrated directly into the screen, allowing to limit horizontal viewing angles without the need for additional accessories.

Users can customize the security level depending on the situation, which is very useful when using the phone in cafes, airports or crowded places. In addition, new mDNIe technology also helps display colors more accurately and naturally than the previous generation.

Performance and AI: the gap is starting to become clear

Galaxy S26 Ultra is equipped with Snapdragon 8 Elite Gen 5 for Galaxy, bringing significant progress in AI processing capabilities. According to an announcement from Samsung, the CPU improved by about 19%, the GPU increased by 24% and especially the NPU increased by up to 39%, helping tasks related to artificial intelligence work faster and smoother.

In fact, the Galaxy S25 Ultra is still powerful enough for most current needs, from heavy gaming to video editing. However, the difference lies in the new generation Galaxy AI experience.

Galaxy S26 Ultra works more proactively with features like Now Nudge or Now Brief, capable of understanding context and providing suggestions right when the user is operating, instead of having to open the application or issue manual commands as before.

The device also runs Android 16 with One UI 8.5 and is committed to software updates for 7 years, helping users feel secure in long-term use.

Camera: familiar parameters but actual quality improved

In terms of hardware, the camera system on the Galaxy S26 Ultra retains the familiar configuration including a 200MP main camera, 50MP super wide angle and two optical zoom telephoto lenses. However, Samsung has upgraded the aperture and lens system, making the ability to capture light significantly better.

In bright enough conditions, photos from the two generations do not differ too much. But when taking night shots or zooming far, the Galaxy S26 Ultra produces cleaner images with noise and retains details better.

In the video recording segment, the device supports 8K 30fps recording and the new APV format, helping to retain more image data for post-production, a big plus for content creators.

Battery and charger: Small but practical upgrade

Both the Galaxy S26 Ultra and Galaxy S25 Ultra use a 5,000mAh battery, providing a usage time equivalent to one day. Thanks to the new chip that optimizes power better, the S26 Ultra has a slight advantage in onscreen time.

The most obvious upgrade lies in the charging speed when the Galaxy S26 Ultra supports 60W fast charging, higher than the 45W level on the previous generation. Samsung says the device can reach about 75% battery in just 30 minutes, significantly shortening charging waiting time.
