Tecnologia Android Samsung Galaxy Z Fold8 Mòbils plegables

Galaxy Z Fold8 canvia de format: 201 grams i una pantalla 4:3

El Fold8 és més curt, ample i lleuger, mentre l’Ultra hereta el format del Fold7. Comparem pantalles, bateria, càmeres, IA i concessions.

El Galaxy Z Fold8 no és simplement un Fold7 més prim. Samsung ha dividit la gamma en dos: el Fold8 Ultra conserva el format alt de telèfon i tauleta, mentre que el Fold8 normal adopta un cos molt més curt i ample, pensat sobretot per veure, llegir i jugar.

Michael Fisher, de MrMobile, els prova després d’onze mesos utilitzant un Fold7. La seva primera impressió ajuda a entendre el canvi millor que una llista d’especificacions: qui busqui el successor directe del Fold7 probablement mirarà l’Ultra; qui vulgui un plegable compacte i gairebé quadrat té ara el Fold8.

1. El canvi principal és la forma

Plegat, el Galaxy Z Fold8 mesura 81,9 × 123,9 × 9,7 mm. És molt més ample i més baix que el Fold7, que mesura 72,8 × 158,4 × 8,9 mm. No desapareix tant dins una butxaca estreta, però evita la sensació de comandament de televisió dels primers Fold.

Desplegat, arriba a 161,4 × 123,9 × 4,5 mm. La pantalla interior de 7,6 polzades té proporció 4:3 en una orientació i 3:4 quan es gira. La pantalla exterior és de 5,5 polzades i utilitza una proporció aproximada de 10:16.

Samsung ha dissenyat aquest model perquè:

  • els vídeos horitzontals ocupin més superfície;
  • els llibres i articles tinguin una pàgina més natural;
  • els jocs rebin un llenç ample;
  • la pantalla exterior funcioni com un mòbil petit i compacte.

El preu d’aquest plantejament és clar: el teclat, algunes aplicacions i certes interfícies poden necessitar adaptació. Una pantalla quadrada tampoc elimina automàticament les franges negres dels vídeos amb formats més panoràmics.

2. 201 grams: més lleuger que molts mòbils convencionals

El Fold8 pesa 201 grams, catorze menys que el Fold7 i que el nou Fold8 Ultra. Samsung el presenta com el Galaxy Z Fold més lleuger fins ara.

La xifra és rellevant perquè un plegable s’utilitza sovint amb una sola mà quan està tancat. Amb funda continuarà sent un conjunt gruixut, però ja no té el pes de les primeres generacions.

El dispositiu incorpora l’estructura de pantalla Flex Titanium. Samsung afirma que combina una pel·lícula d’aliatge de titani amb una placa reforçada per donar suport al panell, absorbir pressió i fer menys visible el plec.

La demostració de MrMobile permet valorar tacte, mida i ergonomia, però no durabilitat. La unitat era de preproducció i només va estar un dia amb els nous dispositius.

3. Fold8 o Fold8 Ultra: no són dues mides del mateix producte

El Fold8 Ultra manté pràcticament les proporcions del Fold7:

  • pantalla interior de 8 polzades;
  • pantalla exterior de 6,5 polzades;
  • 72,8 × 158,4 × 8,9 mm plegat;
  • 4,1 mm obert;
  • 215 grams.

L’Ultra és el model de productivitat, càmera i pantalla gran. El Fold8 normal prioritza portabilitat i consum de contingut. Aquesta separació explica per què el model base pot semblar més radical que l’Ultra.

Per a un usuari de Fold7, el més important no és decidir quina fitxa tècnica és superior, sinó quin format utilitza més:

  • pantalla exterior alta per escriure i consultar notificacions;
  • pantalla interior gran per multitasca;
  • o cos curt i lleuger per lectura, vídeo i jocs.

4. Pantalles a 120 Hz i fins a 3.000 nits anunciats

La pantalla interior del Fold8 és una Dynamic AMOLED 2X de 1.848 × 2.448 píxels, 403 ppp i refresc adaptatiu d’1 a 120 Hz. L’exterior és de 1.248 × 1.972 píxels, 428 ppp i també d’1 a 120 Hz.

Samsung anuncia fins a 3.000 nits, Vision Booster i tractament de baixa reflexió. El valor màxim es mesura en condicions concretes i no significa que tota la pantalla mantingui aquesta brillantor de manera contínua.

En un plegable, la qualitat no depèn només de resolució i nits. També compten el plec, els reflexos, el protector, el tacte més tou del panell interior i com cada aplicació aprofita la proporció.

5. Més bateria que el Fold7, però també una forma diferent

El Fold8 incorpora una bateria típica de 4.800 mAh, davant dels 4.400 mAh del Fold7. Samsung anuncia més de 26 hores de reproducció de vídeo, una dada de laboratori que no representa una jornada amb càmera, 5G, navegació, joc i multitasca.

La càrrega per cable arriba a 45 W i Samsung calcula fins al 63% en uns 30 minuts amb l’adaptador i el cable adequats. La càrrega sense fil és de 20 W i també ofereix Wireless PowerShare.

La capacitat més gran és una millora tangible, però caldrà una prova llarga per saber si compensa la nova pantalla, la brillantor i les funcions d’IA. La primera presa de contacte del vídeo no pot mesurar autonomia ni degradació.

6. Snapdragon 8 Elite Gen 5 i fins a 16 GB

Tant el Fold8 com l’Ultra utilitzen el Snapdragon 8 Elite Gen 5 for Galaxy. El Fold8 s’ofereix, segons mercat, amb:

  • 12 GB de memòria i 256 GB d’emmagatzematge;
  • 12 GB i 512 GB;
  • 16 GB i 1 TB.

També incorpora Wi‑Fi 7, Bluetooth 6.0, 5G, Android 17 i One UI 9. Les opcions i bandes poden variar segons país i operador.

El rendiment real dependrà de refrigeració, límits tèrmics i programari final. Una unitat de preproducció no és adequada per extreure conclusions definitives sobre velocitat sostinguda.

7. La càmera del Fold8 renuncia al teleobjectiu dedicat

El Fold8 té dues càmeres posteriors de 50 MP:

  • principal amb estabilització òptica i obertura f/1,8;
  • ultra gran angular de 120 graus amb enfocament automàtic.

El zoom 2× és de qualitat òptica mitjançant retall de la càmera principal, però no hi ha un teleobjectiu dedicat. És una concessió important en un producte premium, especialment per a retrat o fotografia a distància.

El Fold8 Ultra afegeix una principal de 200 MP i un teleobjectiu 3× de 10 MP, a més de l’ultra gran angular de 50 MP. La diferència reforça la idea que l’Ultra és el model fotogràfic i professional.

El model base incorpora Dual Recording i My FanCam. Aquesta última funció selecciona una persona en un vídeo, la segueix i reformula l’enquadrament automàticament per a xarxes socials.

8. IP48 no significa que sigui impermeable ni hermètic a la pols

El Fold8 té certificació IP48. El segon dígit indica resistència en proves de laboratori sota aigua dolça fins a 1,5 metres durant un màxim de 30 minuts. Samsung desaconsella utilitzar-lo a platja o piscina.

El primer dígit, 4, ofereix protecció davant objectes sòlids de més d’1 mm, però no és una certificació contra la pols fina. Sorra i partícules continuen sent un risc per a frontissa i pantalla.

La resistència a l’aigua també pot disminuir amb cops, reparacions i desgast. No substitueix una garantia específica per danys accidentals.

9. La IA agentiva és una promesa més difícil de provar

Samsung presenta One UI 9 com una plataforma d’IA més proactiva. Now Nudge pot suggerir accions a partir d’una conversa; Gemini Intelligence pot executar fluxos entre aplicacions; i un tauler mostra les automatitzacions fetes pels assistents.

Gemini Notebook pot combinar documents, imatges, gravacions i notes per generar resums, presentacions o àudio. Algunes funcions requereixen compte, connexió, aplicacions compatibles o serveis al núvol.

Aquestes demostracions mostren el potencial de la pantalla dividida, però no garanteixen que l’agent funcioni igual amb totes les llengües, apps i regions. Les funcions d’IA poden canviar després del llançament i algunes poden passar a ser de pagament.

10. El context de la prova importa

Samsung va pagar el viatge i l’allotjament del creador per a l’esdeveniment, però, segons la declaració del vídeo, no va controlar el contingut ni va veure la peça abans de publicar-la.

Fisher havia utilitzat el Fold7 durant onze mesos, però només va tenir aproximadament un dia amb dispositius Fold8 de preproducció. Per tant, el vídeo és especialment valuós per comparar ergonomia i filosofia de producte, no per jutjar bateria, càmera final, resistència o errors de programari.

La disponibilitat general anunciada és el 7 d’agost de 2026. Fins que no hi hagi unitats comercials i proves prolongades, qualsevol veredicte ha de ser provisional.

La conclusió

El Galaxy Z Fold8 fa una aposta poc habitual: en lloc de copiar el Fold7 i fer-lo marginalment millor, crea un plegable més curt, ample i lleuger. Els 201 grams, la bateria de 4.800 mAh i la pantalla 4:3 són atractius, però la falta de teleobjectiu i la geometria radical poden dividir els compradors.

El Fold8 Ultra és la continuació lògica per a qui vol una gran tauleta plegable. El Fold8 normal és la proposta nova: menys ordinador de butxaca i més pantalla compacta per consumir contingut. Aquesta diferència, més que les funcions d’IA, és el que definirà si el canvi funciona.

    Sponsored by Fitnexa. It's Mr. Mobile's favorite time a year. New foldable summer. Samsung's new season hinges on updates to its flip. It's fold and a little something in between. But you know that whenever possible, I like to share with you how the last generation of foldables has aged before we get to the new stuff. Now you get up. Each of your veggies before you have your dessert. Well, that hasn't been in my pocket for the full year. My Galaxy Fold 7 review unit has spent more time as my primary work phone than any other large format foldable, and it's got the scars to prove it. In fact, I've been such a careless carrier, without enduring any repercussions that I got a little overconfident and took it out for some sudden fun on the beach just a few days before seeing the new Fold 8 family.

    That did give me the opportunity to get some great photos, but it also gave me a heart stopper when I went to open the Fold 7 afterward and was greeted by a grinding noise emanating from the hint. Ooh. Yep, some sand found its way in. One granule somehow migrating under the display and it created a pimple at the crease that brought back some very unwelcome memories from 2019 of the first Galaxy Folds failures. Fortunately, this phone hasn't met an untimely demise yet, but I've definitely been treating it with kid gloves ever since. This is why people like me have been calling for years. For manufacturers to focus not just on the water resistance portion of the IP rating, but on the first number also, the one that deals with dust. As spoiler alert, we are not going to get much reassurance on this front when we turn the page to see the full date in a moment. First, let's finish up the Fold 7's long-term report card. As tense as happen, my initial concerns have blossomed into annoyances over the months. The battery that lasted just long enough at the beginning is now something I need to

    baby a bit. I make sure not to leave the house without a USB cable for the car or a battery pack for everywhere else. It still does get me through a full day and my usage is quite heavy. without much margin for error. The lack of magsafe continues to chave, the camera quality still doesn't quite justify the wobble, especially when you hold it up against some of the competition. And while Samsung isn't the worst offender when it comes to emulating Apple's software design, it does it more than I'd like. But that is a small price to pay in exchange for timely, platform updates. Samsung deserves praise for delivering on its promises here. As I shot this video, my fold 7 sample was sitting at Android 16 with a security patch current up to this month. Meanwhile, the one UI version of Android 17 is in beta with release expected next month. So, it's not too shabby compared to much of the competition. Performance hasn't slowed at all over the past year either, which helps justify the The expensive silicon Samsung keeps packing in year after year.

    Another spoiler. All three of the phones you're about to see, pack the newest top shelf snap dragon chipset yet again. And possibly the thing that's aged the best for me is the design. The fold 7 was one of the thinnest and lightest foldables ever made when it dropped. And every time I pick it up, a little part of me is still so impressed that this much phone fits in a package this pocketable. At Prestheim it's down $500 from its launch price. So 1499 and that plus the other upsides I just mentioned makes it one of the rare foldables I'd still recommend a year after its launch. It just keep it away from the beach. Next up it's off to London to see the fold eight family and all its titanium back to glory. first, you can see it in my eyes, I need some sleep. You know what I love about sleep? Absolutely everything. You know what interferes with sleep though. Almost anything. So when I'm traveling for events like this I often try to use earbuds to protect that sleep, but I'm a side sleeper so I haven't found any buds small enough to sleep with comfortably. Until now, these are the so many pods 3 from my sponsor Fitnexa. They're the smallest earbuds I've ever used, tiny enough that they don't get jammed into my ear canals when my head hits the pillow.

    But they've still got active noise cancellation, which means the roar of airplane engines, or having a hotel room too close to the elevator, isn't a problem for me anymore. I imagine this would also help suppress a snoring partner, but I wouldn't know anything about that. Of course you can play whatever audio you like through the Sony pods, but I enjoyed trying out the Fitnexa app with its mix of natural soundscapes, meditation, and noise colors across the spectrum. Check out Sony Pods 3 at the link in the description and that link will automatically take $10 off. Thanks to Fitnexa for sponsoring this video. Part 2 requires a little disclosure here Samsung flew me to London along with a few plain loads of other media to see its new foldables, but I do my absolute best not to let that affect my editorial opinions. Samsung does not get to approve or even see my videos before release and it does not pay me to produce them. If I were a paid Samsung influencer, I probably wouldn't be able to complain as much about, well for example, the absence of magnets on these phones. You need to buy a magsafe case to stick these to anything. Or the dollar colors of this year's collection, or the continued lack of proper dust resistance. Yet on that that four, full year, it's better at keeping out ants than dust bunnies.

    All of those are bummers of various degrees. That said, if you saw my latest episode of Into the Fold, you knew I was going to be excited about this. This is the Galaxy Fold 8, usher is in the second coming of wide foldables. Yes, Oppo, and Google, and even Microsoft did it first, and Apple will likely do it next, but for now, the Fold 8 is special. This phone is all about aspect ratios, 10 to 16 on the cover display, 4 to 3 landscape on the interior, and therefore 3 to 4 in portrait if you rotate at 90 degrees. It's important on the inside, not just because it's a little friendlier for video, but because it gives you more canvas to split apps side by side. This is still, in part, a productivity play. And on the outside, the squatter covers green finally gives Samsung a product it can offer to those who've always found the fold a little too tall to use one handed, or a little to narrow it a type on. The Vultade shares some upgrades with its stable mate, the more familiar Vultade Ultra, namely a display with 3,000 nits of peak brightness, up from 2600 last year, and a new anti-reflective coating, which was sorely needed to keep these competitive. A each phone also replaces a layer of polymer beneath the display with titanium alloy

    film for more durability and reduced thickness. While the creases aren't quite as zero feel as Oppo achieved on its Find N6, that's the only downside I can see at this point. Overall, the display on each fold 8 is very impressive. And you can really feel the weight savings on the wide-boi in particular. 200-1 grams gives it the perfect amount of heft. As soon as I picked it up, I suspected this would become my new GoTo Foldable. There's just something so right about the way this feels. Unfortunately, the Fold 8 isn't likely to be a content powerhouse with this slightly unneemack optical array. For nearly $1900, I need a good telephoto camera, and we've seen it done on the Pixel Fold, which is close to the size and shape. But the Fold 8 settles for just a main and an ultra wide, both at 50 megapixels. I passed through company reps about this and they say it's all about optimizing for a specific kind of buyer. Those who want better zoom shots will apparently be referred to the $1,100 full-date Ultra with it. Well, I'm sorry. This thing still models through with a 10 megapixel 3x. I mean, I haven't reviewed it yet, but ah.

  8. 9:21 , obre el vídeo en una pestanya nova

    Yeah. Well, at least there's slightly better news on the batteries. Samsung is still conservative when it comes to capacity, but 4800 mAh on the full date, and 5,000 on the Ultra, at least bring the foldable's closer to alignment with the Galaxy slabs. And charging speeds of 45 watts wired and 21W less, up from 25 and 15 last year, are welcome improvements also. Finally, less we forget, there's also a flip-eight coming to market. At first glance, it doesn't seem like a big change year over year, and that's to be expected. 2025 was a big leap forward for this product line, so a little modest iteration is no surprise. Nor, sadly, is the price bump to $1,200 starting. The component cost inflation of the rampocalyps continues to haunt us all. Well, the flip doesn't get the new satin display finish of its siblings, or the new titanium layer underneath, but by shaving a few grams and millimeters off the last model, Samsung has made the flip-aid the thinnest and lightest flip-bone out there. And even more important, to nerds like me at least, is what this new cover display brings

    with it. We can finally, easily add apps to the outer screen. like Motorola has been offering for six years or so. Hey, better late than never. Actually, Snark aside, Samsung has actually gone a few extra steps here and we thought it's approached to the entire Cover Screen Experience. There's now something called Flex Window Home, which is a home screen with glanceable insights that keep you informed and let you take some actions without opening the flip. Now I've held off on saying, AI, all video long. you're welcome. But this is the kind of AI that I genuinely do find useful. If it's implemented properly, Samsung's track record hasn't been great about that so far, looking at you now, bar, but even if this fizzles, when you factor in the simple and effective widget layout, Samsung's rethought approach to notification and system controls and the existing fun of animated wallpapers and games out here, the Galaxy Flip might finally be giving the Razor a run for its money in the cover display department. Are these the phones that will finally kickstart the foldable revolution? No, I don't think so. Before Digit price tags,

    compromises and durability and cameras and utility that's just not apparent to enough normal people to overcome those drawbacks. It's totally fair if you're not into this category. But if Apple does enter the space, as expected, in a couple months, and it has the usual effect on the rest of the market, we're about to see the biggest surge in foldable interest maybe since the very beginning. With mature products and flip and fold, and what looks to be a strong start in the hybrid subcategory, Samsung seems like the company in the best position to lead the foldable conversation as we head into this new era. whether that turned out to be true will depend on how good these actually are in the real world. So stay tuned for my reviews of all of these coming soon on Mr. Mobile. Folks, as I mentioned, Samsung did provide travel and lodging so I could attend Samsung unpacked in London. All of the devices featured in this video are review samples provided by Samsung but as always, no company ever has editorial input or copy approval rights concerning my review content. Please subscribe to Mr. Mobile so you don't miss those reviews coming soon. And if foldable products are your thing, I've covered almost all of them, so feel free to dive into the backlog. Until next time, from Michael Fisher, Captain Two phones on Socials, thanks for watching and stay mobile, my friends.
