The phone is finally here. Samsung dropped three new foldables at Galaxy Unpacked. But the real headline? The Galaxy Z Fold 8 Ultra. It’s the first “Ultra” in the folding lineup. Last year’s Fold 7 stays on sale. It’s powerful. Cheap? Only if you hunt for deals.
The Z Fold 8 enters the chat with a wide-fold design. The Ultra? That’s the direct successor. The prices remain steep. Most people can’t just grab one. But the upgrades aren’t just specs on a page. They’re in how the phone feels in your hand. The anti-reflective coating? Huge. The battery life? Finally competitive. Still, the Fold 7 holds up. Especially on sale.
So what changed? Let’s break it down.
Design and Display: Easier to Unfold
The Galaxy Z Fold 8 Ultra isn’t much bigger than the Fold 7. Same weight. One millimeter slimmer when open. But the sides tell the story.
Samsung slimmed down the edges. There’s a gap now. A tiny one. But it lets your thumb catch the hinge. Unfolding the Ultra feels natural. Smooth. The Fold 7? Flat sides. Zero gap when shut. You have to pry it open sometimes. It’s annoying.
The screens look identical from a distance. Both have 6.5-inch covers and 8-inch inner displays. 120Hz refresh rate across the board. But hold them up to a window.
The Ultra hits 3,000 nits. The Fold 7 tops out at 2,600. More importantly? The matte finish. And that anti-reflective coating I wanted. Glare disappears. Readability outdoors? Night and day. I held them side-by-side under harsh indoor lights. The Fold 7 was a mirror. The Ultra was just a screen.
Then there’s the crease. It’s still there. You have to look for it. But it’s less prominent. Samsung swapped the internal structure for titanium-alloy film and a better plate. They claim it balances hinge mechanics and magnetic force. The result? Less resistance when opening. It feels lighter.
Both phones are IP48. Not IP68. That means dust smaller than 1mm gets in. Water? Fine for 30 minutes. Don’t dunk it in a pool. Unlike the Google Pixel 10 Pro or Honor Magic V6, these aren’t dust-tight. Just water-resilient.
Battery and Performance: The Silicon-Carbon Shift
Under the hood, the brain is sharper. The Galaxy Z Fold 8 Ultra uses the Snapdragon 8 Elite Gen 5. The Fold 7 runs the previous Snapdragon 8 Elite. Both get up to 16GB RAM in the top tier. 256GB starts at 12GB.
Samsung claims better heat dissipation. More internal space. Theory says less throttling. Practice? We’ll see.
The real win is the battery. Samsung switched to silicon-carbon anode tech. Capacity jumped from 4,400 mAh in the Fold 7 to 5,0000 mAh in the Ultra. Charging hit 45 watts. The old one? 25 watts.
Chinese rivals still laugh at this number. Oppo and Honor pack over 6,000 mAh cells. But for a Samsung phone? This is a big step. Will it last a full day of heavy use? Probably. For the first time in years.
Wireless charging works via Qi. No magnets inside. Want MagSafe accessories? Buy a case. Extra cost. Standard fare for Samsung right now.
Cameras and AI: Incremental Gains
The camera setup is mostly the same. 200MP main sensor. 10MP telephoto with 3x zoom. These stay.
The ultrawide got a boost. From 12MP to 50MP. Expect better detail in wide shots. Don’t expect miracles until independent tests roll in. Video shooters might prefer the new model though. The Ultra adds APV codec support. Plus a Cine LUT. That’s cinematic color control straight from the device. Professional editors will like the workflow flexibility.
Software-wise, we’re looking at Android 16 on the Fold 7. The Ultra ships with Android 17. Both run One UI 9 eventually. The Z Fold 7 will update to the new OS. So the experience stays similar.
AI features are everywhere. AI Select for searching on-screen text. Object eraser in the Gallery. Now Nudge pops up contextually. Sending a calendar invite in a text? The phone suggests adding it to your calendar. It’s helpful. Sometimes intrusive.
There was a demo of “agentic AI.” Supposedly, it could book a hotel from a photo of the Eiffel Tower. It failed. Badly. Unreliable in its current state. But Samsung promises seven years of updates for the Ultra. The Fold 7 gets six. Plenty of time to fix the kinks.
The gap between generations is shrinking. But the price gap is widening.
Final Thoughts
The Galaxy Z Fold 8 Ultra is a refined evolution. Better screen. Longer battery. Easier hinge. The Fold 7 is still a beast. If you find a discount, ignore the Ultra. If you want the best screen clarity and battery life? The Ultra is worth the extra cash.
But wait for real-world battery tests. The specs look good on paper. Daily use is a different story. And that AI? Treat it like a beta feature. Not a replacement for your brain.
Which one fits your pocket? That’s the real question.
