Samsung's Passport-Style Fold 8 and Ultra Foldable: A Redesign Betting Subtraction Beats Specs

Samsung wants you to believe it made three brave phones this year. It made one.

That's the tension buried under the marketing. Samsung's whole 2026 foldable pitch runs on a word it keeps repeating in different costumes: subtraction. PCMag put it bluntly at Unpacked in London — "Can you really improve a phone by removing things from it?" It's a great question. The honest answer is that Samsung only earned a yes on the cheapest, weirdest device in the lineup.

Last week we flagged Samsung "folding" as a headline. This week the devices are real, the spec sheets are out, and the verdict lands: buy the passport, hesitate on the Ultra, skip the Flip.

The honest answer is that Samsung only earned a yes on the cheapest, weirdest device in the lineup: buy the passport, hesitate on the Ultra, skip the Flip.

Start with the phone that actually got the subtraction treatment. The Galaxy Z Fold 8 — the standard one, not the Ultra — is a genuine redesign, not a refresh. Samsung threw out the tall-and-skinny profile that every book-style foldable has worn for years and built a short, wide slab. The Aussie Corporate's line is the cleanest: it "looks more like a passport than a remote control."

That shape change is the whole argument. Fold it, and the 10:16 cover screen still feels like a normal phone for messaging and short video. Open it, and the 7.6-inch inner display is 4:3.

Why does 4:3 matter? Because the old tall foldables left black bars or awkward crops all over your video. The 4:3 canvas makes movies, photos, websites, and social content fill the screen the way a small tablet would. Rotate it and that same ratio turns into a natural page for reading e-books and long articles.

Here's the number that makes it real: 201 grams. That's Samsung's lightest Z Fold ever, and per Digital Trends it's lighter than an iPhone 17 Pro — and more than 40 grams lighter than the Motorola Razr Fold one reviewer was carrying. A book-style foldable that undercuts a slab flagship on weight is not a gimmick. It's a category shift.

What did Samsung remove to get there? The telephoto lens, entirely. The Fold 8 ships with a 50MP main and 50MP ultrawide and no zoom lens. That's the trade: short-and-wide, media-first, feather-light — at the cost of reach in your camera.

And that trade is honest, because the phone knows what it's for. If you consume more than you produce — if your foldable is mostly a pocket screen for watching, reading, scrolling, gaming — the missing telephoto costs you almost nothing and the 4:3 screen improves your day every single time you open it.

That's what subtraction is supposed to mean. Now watch it fall apart on the other two.

The Fold 8 Ultra is a very good phone that mostly does the opposite of subtract. Samsung stacked it: an 8-inch inner display, up to 3,000 nits on both screens, a 200MP main sensor, a 50MP ultrawide with autofocus, a 10MP telephoto, up to 16GB of RAM and 1TB of storage. It's 4.1mm unfolded and 215g — Samsung's slimmest Fold design.

It is, by every account, the best-built Fold Samsung has ever made. The problem is the price and the timidity underneath it.

The Ultra costs $2,099. That's the "buy everything" tax, and if you must have 200MP and a telephoto in a foldable, it's the phone. But it's a polish job on a mature formula — a refined hinge, a smaller crease, an anti-reflective coating — not a reinvention.

Then there's the battery, which is where Samsung's "we're being brave" narrative gets tested against the rest of the market. The Ultra debuts silicon-carbon battery tech, finally. Silicon-carbon swaps some graphite in the anode for silicon, which holds more lithium and lets you pack more capacity into the same space — exactly the kind of engineering a cramped foldable should devour.

And Samsung's first swing is 5,000mAh in the Ultra, 4,800mAh in the Fold 8. Real gains — the Ultra's cell is about 14% bigger than the Fold 7's 4,400mAh, in a body that got thinner. Fine.

But look who's already in this pool. The Honor Magic V6 packs a 6,660mAh silicon-carbon cell in a 4mm body. Motorola's Razr Fold runs 6,000mAh with 80W wired and 50W wireless charging. Samsung's Ultra tops out at 45W wired and 20W wireless.

Samsung's defense, per its own briefings, is caution: it's prioritizing longevity and safety over headline capacity, limiting silicon content until it trusts the long-term behavior. Given Samsung's battery history, that's defensible. But "we chose to do less than the competition can already do" is not the same brave subtraction story as the Fold 8's — it's just a conservative first step wearing bold language.

So the Ultra verdict: buy it only if you genuinely need the 200MP sensor and the telephoto, and only if $2,099 doesn't make you flinch. Everyone else is paying flagship-plus money for iteration.

And then there's the Flip 8, where the subtraction pitch stops being generous and starts being a bill.

The Flip 8 raises the price from the Flip 7's $1,099.99 to $1,199.99 — a flat $100 hike. For that extra hundred dollars, here's what you don't get.

You don't get the anti-reflective coating that makes the Fold screens easier to read outdoors; Samsung reserved that for the Folds. In fact, ZDNET and PCMag both note the Flip 8 reuses the Flip 7's OLED panels outright. Same 4.1-inch cover, same 6.9-inch inner screen.

You don't get a bigger battery. It's still 4,300mAh, still 25W wired and 15W wireless. It adopts the silicon-carbon chemistry and then does nothing visible with it — same capacity, same charging as last year.

The cameras look recycled too: 50MP main, 12MP ultrawide, 4K60 video, unchanged on paper from the Flip 7 and arguably the Flip 6.

Now put it next to the Motorola Razr Ultra, which the Flip 8 undercuts by $300. Motorola gives you a 5,000mAh battery, 68W wired charging, 30W wireless, a 165Hz display hitting 5,000 nits, and 8K video. On raw hardware, the cheaper-than-Motorola framing is the Flip 8's strongest argument, and it's an argument about what you're not spending, not what you're getting.

To be fair, the Flip 8 isn't a bad phone. It's genuinely slimmer and lighter — 6.1mm and 180g, down from 6.5mm and 188g. The Snapdragon 8 Elite Gen 5 for Galaxy is a real jump from the Flip 7's Exynos: per ZDNET, 30% faster CPU, 25% faster GPU. And the new FlexWindow finally makes the cover screen useful, with a six-window card system and real app access.

But none of that is subtraction improving your day. It's a spec bump and a software update sold at a $100 markup on recycled panels and a battery that trails its rivals.

So the Flip 8 verdict writes itself: skip it — unless you're coming from a phone that's several years old, in which case any modern clamshell will delight you and this one is fine. If you own a Flip 7, there is nothing here worth $1,199.99.

Which brings us back to the word Samsung kept saying. Subtraction only counts as a virtue when the "less" actually improves your day.

The Fold 8 dropped a telephoto and a familiar shape and handed you a 201-gram, 4:3 media machine that's lighter than an iPhone 17 Pro. That's real. The Ultra added everything and charged $2,099 for polish. And the Flip 8 subtracted nothing, changed nothing important, and raised the price anyway.

Buy the weird one. It's the only phone in the lineup where removing things actually made your life better.
