Samsung Galaxy S26 Ultra vs S25 Ultra vs S24 Ultra: Is It Time to Upgrade?

Three generations. One deep-dive. Everything you need to know before you buy — or trade in.

Every year, Samsung drops a new Ultra — and every year, the question is the same: is the upgrade actually worth it? In 2026, that question is more interesting than ever. The Galaxy S26 Ultra arrived in March with a headline-grabbing world-first Privacy Display, the fastest Snapdragon chip ever fitted to a Galaxy phone, and a return to an aluminum frame — a quiet but deliberate design choice. Meanwhile, the S25 Ultra remains a legitimately stellar device, and the S24 Ultra — now two generations old — is available at prices that would have seemed impossible a year ago.

Whether you're a power user looking to stay on the cutting edge, a casual photographer chasing better night shots, or someone ready to trade in an older device and finally upgrade, this guide breaks down every meaningful difference — no marketing fluff, just the facts.

Screen Technology: The Privacy Revolution

On the surface, all three displays look almost identical — QHD+ Dynamic AMOLED 2X panels with 120Hz adaptive refresh rates and blazing 2,600-nit peak brightness. Real-world viewing quality across these generations is genuinely competitive.

But the S26 Ultra introduces something the smartphone industry has never seen: a built-in Privacy Display. When activated — manually or automatically when typing passwords or using specific apps — the display's viewing angle narrows dramatically. People looking over your shoulder see a dark screen; you see everything normally. This is hardware-level panel technology from Samsung Display, not a software trick.

For professionals or frequent travellers handling sensitive data, the Privacy Display alone may justify the upgrade from the S25 Ultra.

Chipset & Performance: A Three-Generation Leap

The S24 Ultra's Snapdragon 8 Gen 3 for Galaxy was the fastest mobile chip of 2024. The S25 Ultra's Snapdragon 8 Elite leapt ahead — roughly 45% CPU uplift. The S26 Ultra's Snapdragon 8 Elite Gen 5 pushes even further. Critically, it runs globally — no Exynos variant for any market.

In daily use all three phones feel extremely fast. The S26 Ultra's lead becomes tangible for sustained gaming, real-time AI processing, and demanding video editing workflows.

Camera: Where the S26 Ultra Pulls Ahead

The camera story across these three generations is nuanced and genuinely important for anyone who cares about photography.

The S24 Ultra → S25 Ultra jump

The biggest hardware upgrade was the ultra-wide camera — from 12 MP to a class-leading 50 MP module. This dramatically improved ultra-wide and macro shots, especially in low light. ProVisual Engine processing improvements added further real-world gains.

The S25 Ultra → S26 Ultra jump

The headline upgrade is the wider main lens aperture: f/1.4 versus f/1.7 on both predecessors — allowing approximately 47% more light to reach the sensor for cleaner, brighter low-light shots. The 5× telephoto also benefits from a wider aperture (f/2.9 vs f/3.4) and a new All Lens On Prism (ALoP) mechanism. Super Steady with Horizon Lock keeps footage level in real time. The S26 Ultra is the first phone to support the APV professional video format at 8K@30fps.

Galaxy AI: How Each Generation Stacks Up

AI is no longer a buzzword on Samsung's Galaxy S Ultra line — it's the central value proposition. Each generation has meaningfully expanded Galaxy AI's capabilities.

S24 Ultra: Where Galaxy AI Began

Circle to Search, Live Translate, Chat Assist, Transcript Assist, and the first iteration of Photo Assist arrived with the S24 Ultra — features that felt genuinely transformative at launch and still deliver real value today.

S25 Ultra: AI Deepens with Now Brief & Personal Data Engine

The S25 Ultra introduced the Personal Data Engine — an on-device secure database that allows Galaxy AI to learn your habits without sending data to the cloud. This powers Now Brief and Now Bar. Gemini AI integration deepened, and Galaxy Log enabled cinematic video capture.

S26 Ultra: AI Becomes a Creative Studio

Photo Assist can now add objects and elements to scenes — transforming day photos to night, replacing backgrounds, or applying dramatic style changes. Creative Studio accepts mixed inputs (sketches, text, images) to generate stickers, wallpapers, and custom designs. The enhanced NPU in the Snapdragon 8 Elite Gen 5 makes all on-device AI tasks faster and more capable.

Battery Life & Charging: The S26 Ultra Finally Catches Up

All three phones carry a 5,000 mAh battery. The S25 Ultra saw a modest efficiency improvement over the S24 Ultra (~30 mins more video playback). But the big story for the S26 Ultra is 60W wired charging — up from 45W on both predecessors and the fastest wired charging speed ever on a Galaxy S Ultra. Note: no charger is included in the box.

Wireless charging is 25W (Qi2.2) on the S26 Ultra — matching the S25 Ultra's Qi2.1, while the S24 Ultra is capped at 15W wirelessly. All three support reverse wireless charging for Galaxy Buds.

Design: Aluminum is Back — and It Works

The S24 and S25 Ultra both used premium titanium frames. The S26 Ultra returns to Armor Aluminum — the first time since the Galaxy S23 Ultra. The practical result: 4g lighter than the S25 Ultra (214g vs 218g) and 18g lighter than the S24 Ultra (232g). It's also 7.9mm thin versus 8.2mm and 8.6mm on predecessors. Corner rounding has been softened slightly, aligning with Samsung's broader design language. The S Pen remains integrated, as always.

Who Should Upgrade — and to What?

Here's our honest, practical recommendation based on where you're starting from:

If you own an S25 Ultra

The S26 Ultra is a genuine upgrade, but not dramatic. The f/1.4 aperture, 60W charging, and Privacy Display are the three standout reasons to switch. Trade in while your S25 Ultra commands strong resale value. If none of those matter, hold for the S27.

If you own an S24 Ultra

This is a meaningful upgrade gap. The S24 Ultra misses the 50MP ultra-wide, the Personal Data Engine, faster wireless charging, lighter design, and now the S26 Ultra's aperture and 60W charging. Trading in now — while resale value holds — is a worthwhile move.

If you own an S23 Ultra or older

The S26 Ultra is a comprehensive upgrade across every category. Go for it. If budget is a consideration, the S25 Ultra at a reduced price is still a significant leap from anything pre-S24.
