Samsung S25 Ultra vs. S24 Ultra: Is the AI Worth the Upgrade?

As we move deeper into 2026, the smartphone landscape has shifted from a “specs war” to an AI-driven era. Samsung’s latest flagship, the Galaxy S25 Ultra, has officially taken the throne, but many users are asking: Is the Galaxy AI on the S25 Ultra truly revolutionary, or can the S24 Ultra still hold its own?

In this guide, we break down the hardware, software, and—most importantly—the Artificial Intelligence to see if you should make the jump.

The Big Comparison: At a Glance

Is the AI Actually Different?

The S24 Ultra introduced us to the first generation of Galaxy AI, including Circle to Search and Live Translate. However, the S25 Ultra leverages the Snapdragon 8 Elite chipset, which features a significantly faster NPU (Neural Processing Unit). This allows for on-device AI processing that is faster and more private.

Key AI Exclusives for the S25 Ultra:

• Now Brief & Now Bar: A contextual lock-screen experience that summarizes your weather, schedule, and health data the moment you wake up.

   

• Cross-App Actions: You can now ask Gemini to perform tasks across multiple apps, like finding a recipe from a video and adding it to a list.

   

• AI-Driven Nightography Video: Uses real-time AI noise reduction for cleaner low-light clips.

   

• ProScaler: Improves display scaling by up to 40%, making lower-resolution content look native.

   

Performance: The “Elite” Edge

The transition to the Snapdragon 8 Elite is the biggest hardware jump in years. It isn’t just about raw speed; the S25 Ultra handles multitasking and gaming with improved efficiency, keeping the phone cooler during intensive tasks.

Design and Ergonomics

The S25 Ultra moves away from the “boxy” corners of the S24 Ultra in favor of rounded corners and a thinner titanium frame.

Key Takeaway: If the S24 Ultra felt too heavy, the 14g weight reduction and ergonomic curves make the S25 Ultra significantly more comfortable for one-handed use.

Frequently Asked Questions (FAQs)

What is the advantage of S25 Ultra over S24 Ultra?

The S25 Ultra offers a lighter design (218g vs 232g), a slightly larger 6.9-inch display with thinner bezels, and the Snapdragon 8 Elite chip, which provides a massive boost in AI performance and power efficiency.

What is the difference between S25 and S24 AI features?

While the S24 Ultra has basic Galaxy AI, the S25 Ultra features on-device AI for faster processing. It also includes the Now Brief lock screen and ProScaler image enhancement, which relies on the newer NPU.¹

Is upgrading to S25 Ultra from S24 Ultra worth it?

It is a minor upgrade for most. However, if you want a lighter phone with rounded corners or if you are a power user who needs the faster Snapdragon 8 Elite for gaming or heavy AI tasks, the upgrade is worth it.

Is the S25 Ultra camera better than the S24 Ultra?

Yes, primarily due to the 50MP Ultrawide sensor (up from 12MP). It allows for 8K recording on the ultrawide lens and significantly better low-light AI processing.

Is the Galaxy S25 Ultra worth it?

As a flagship phone, it is arguably the best Android device on the market in 2026. If you want the absolute peak of mobile technology, it is worth the investment.

Is the S25 Ultra durability better than the S24 Ultra?

The S25 Ultra uses Gorilla Armor 2, which is reported to be more shatter-resistant than the original version on the S24 Ultra, though some tests suggest the S24 Ultra might have slightly better scratch resistance.

Is Samsung S25 better than S24?

Yes, the entire S25 lineup features better energy efficiency and the Snapdragon 8 Elite globally, replacing the Exynos chips found in some S24 regions.

Does the S25 have a better display than S24?

Yes. While both have high peak brightness, the S25 Ultra uses a Dynamic AMOLED 3X (or 2X refined) panel that offers 43% better vibrancy and improved sunlight legibility.

Is S24 worth buying in 2025/2026?

Absolutely. With the launch of the S25, the S24 Ultra has seen a massive price drop, making it one of the best value-for-money flagship purchases today.

Is the Samsung S25 Ultra too big?

Despite the larger 6.9-inch screen, the S25 Ultra is actually narrower and thinner than the S24 Ultra, making it feel smaller in the hand.

Why is the Galaxy S25 Ultra cheaper than the S24 Ultra?

Actually, the launch price was similar, but you may find it “cheaper” through specific carrier deals or trade-in promotions that Samsung pushed aggressively at launch.

Is the S25 Ultra a flagship phone?

Yes, it is Samsung’s premier flagship, sitting above the S25 and S25+.

Which is best to buy, S24 Ultra or S25 Ultra?

• Best Value: S24 Ultra (still powerful, much cheaper).

   

• Best Experience: S25 Ultra (lighter, better AI, better ultrawide).

   

Will the S25 Ultra have a better display?

Yes, it features minimized bezels and a 40% improvement in image scaling quality via AI.

Is S25 Ultra lighter than S24 Ultra?

Yes, it is 14 grams lighter, weighing in at 218g compared to the S24 Ultra’s 232g.

The Verdict

The Samsung Galaxy S25 Ultra is a refined, “smarter” version of its predecessor. If you are coming from an older device (S21, S22), the jump is monumental. If you already have an S24 Ultra, you’re mostly upgrading for the comfort and the cutting-edge AI processing.
