Motorola Razr Fold vs Galaxy Z Fold 8 Ultra: Main differences
0
Motorola has had a very formidable presence on the clamshell foldable phone market for years now, but it didn't compete in the slightly more premium book-style foldable niche. The latter has been dominated by Samsung and a few other key players, but it's the South Korean giant that's domineering the niche. 

Well, this changes this year, as the Motorola Razr Fold has joined the ranks of large foldables you can buy, and it's actually a pretty decent deal. That's largely in preparation for the arrival of the foldable iPhone, which, if history repeats itself, could potentially dominate the industry in a couple of years' time. Brands are increasing their efforts in order to have the best possible footing for the upcoming clash. 

Meanwhile, Samsung just announced the Galaxy Z Fold 8 Ultra on July 22, and it's the same familiar book-style foldable as previous Folds, but with some key upgrades and improvements that most fans have been asking for for years. Here's how it compares against the Moto Razr Fold.

Design and Size

Can Motorola easily pull off what took Samsung years to achieve?


The Motorola Razr Fold looks like something we've already seen, as it doesn't stray away from the already established design language and overall presentation of a foldable phone

It is a moderately thin device that relies on the usual aluminum/glass sandwich build. All pretty modern and posh, just like most Motorola foldables out there. The exact dimensions and size are still kept secret by Motorola, but we'd probably get them in due time. 

Motorola has also outfitted the phone with IP49 water and dust resistance, which means it's not completely dust-proof but would survive even strong water jets. 

The Galaxy Z Fold 8 Ultra retains the general looks of the Galaxy Z Fold 7, but comes with some key upgrades in the build. For example, it now has magnets in the build that improve the opening and closing of the device. That's a change inspired by the TriFold. 

Samsung has also thrown in a titanium plate beneath the display as well as an ultra-thin titanium alloy film that's less than 30% the width of a single human hair all in order to further make the crease shallower and non-existent. 

Colors-wise, the Galaxy Z Fold 8 Ultra is available in Violet Shadow, Cream, Graphite, and Violet Green (exclusively online). The Motorola Razr Fold arrives in Blackened Blue and Lily White, both Pantone-certified colors.  

Display Differences



At PhoneArena, we do our own display lab testing and it reveals something very interesting. Motorola claims it can reach 6,200 nits of brightness, which is incredibly high, but our measurements show that this is misleading. Some phone makers only use a tiny white dot on an all black screen, apparently that’s what Motorola used for that number. If you use a realistic scenario with 20% white box on the screen, we measured the Samsung actually gets brighter, reaching nearly 2,900 nits vs 2,100 nits on the Motorola.

Display Measurements:



 
And it has one other advantage. At night, when you turn off the lights, the Motorola cannot dim low enough and it might be a bit too bright at nearly 3 nits, while the Samsung drops well below 1 nit, much easier on the eyes.

And take a closer look at the crease in the middle. The Galaxy is nearly flat, while the groove is deeper on the Motorola. Add the new stronger titanium flex tech that supports that screen on the Samsung and the display round definitely goes to the Galaxy.

However, there is one important thing to note here: the Razr Fold actually supports the Moto Pen Ultra stylus, which has pressure sensitivity, tilt detection and low-latency, so it’s great for writing and drawing, while Samsung has removed support for the S Pen in the Fold.

Performance and Software

Benchmark race

It's the Qualcomm Snapdragon 8 Gen 5 that powers the Moto Razr Fold, a big step down from the flagship-grade Snapdragon 8 Elite Gen 5 on the Galaxy.

Wild Life Extreme is a heavy graphics workload used to measure a device's sustained GPU performance and thermal throttling. It uses older mobile rendering techniques and is friendly to older or lower-end mobile devices.

Steel Nomad Light Stress Test: Measures your phone's 'gaming stamina' by comparing its peak speed (High) against its throttled speed after it heats up (Low), revealing whether your performance will stay smooth or start lagging during a long session. It loads heavier, more modern effects than Wild Life Extreme and is more in line with current games.

Ray Tracing: The test measures Ray Tracing performance because this advanced technology creates the hyper-realistic reflections and shadows found in next-gen titles like Arena Breakout. Even if you don't play games with ray tracing, a high score here means your phone has a 'best-in-class' cooling system.


Memory-wise, the Moto Razr Fold arrives with 16 GB of RAM and 512 GB of storage. The Galaxy Z Fold 8 Ultra, despite its higher price, only features 12 GB of RAM and 256 GB storage in its base model. You can pay extra to get the 512 GB version (also with 12 GB RAM), or pay even more for the 1 TB version and only that one carries 16 GB of RAM.

We get a triple-camera setup on the Moto Razr Fold. The phone features a triple camera consisting of a 50 MP main, a 50 MP ultrawide, and a 50 MP telephoto with a 3X optical zoom.

Meanwhile, Samsung is bringing a host of mostly software improvements to the Galaxy Z Fold 8 Ultra, like an enhanced ProVisual engine that delivers a more advanced low-light video processing. There's also more flexible 8K video recording and editing, support for Samsung's efficient APV codec, as well as four new cinematic LUTs for on-device color grading of your log video.

Hardware-wise, both phones have roughly the same sensor size for the main camera and the ultra-wide one, but the Motorola has a nearly four times larger sensor for the 3X telephoto camera, so that's a massive advantage.

Zoom Quality






While the Fold 8 Ultra is limited to 30X zoom for photos, the Motorola can zoom all the way up to 100X. The quality, however, is just not very good, and you can notice the excessive AI-fication of the text that has turned it into a jumbled mess.

Summary


This might be Motorola's first book-style foldable, but it arrives with a much bigger battery, faster charging, more RAM, a better zoom camera and some cool software tricks like the three app card-style multitasking. It also has stylus support if you care about that and a much cheaper price.

The Galaxy has a faster processor, an almost invisible crease, it’s thinner, lighter, has a few extra AI tricks, but... that’s it.

Are these Samsung advantages worth the premium price? For some people like gamers and those who value a slim phone, yes. But my biggest problem with foldables is the price: they cost a ton of money, and if you don’t mind a slightly heavier phone, I think Motorola might just be the smarter purchase.
