Samsung Galaxy Z Fold 4 vs. Z Flip 4: best foldable battle

They may still seem like a novel concept, but foldable phones have already come a long way. When Samsung released its first foldable — the Samsung Galaxy Fold — in the fall of 2019, it suffered from a number of teething problems, including concerns about its durability and its impractically small front screen. Now, the device is into its fourth generation, with the South Korean tech giant revealing the Galaxy Z Fold 4 and its sibling, the Galaxy Z Flip 4, as part of its Galaxy Unpacked event.

Both devices show just how much Samsung has refined the foldable phone concept, with each boasting more durable screens, enhanced processors, and software that takes fuller advantage of each mobile’s foldability. Anyone new to folding phones may be wondering which of Samsung’s two devices is better for them. That’s where this head-to-head comparison comes in, with each device being put through its paces and evaluated according to its specs, performance, design, display, battery, cameras, and software.

By weighing up each phone against the other, it should help you decide which way to go.

Design, display, and durability

Andrew Martonik/Digital Trends

Neither the Samsung Galaxy Z Fold 4 nor the Galaxy Z Flip 4 are a major departure from the designs of their respective predecessors, but they vary from each other in important ways.  The Fold 4 is the bigger sibling of the pair, featuring a 7.6-inch AMOLED 2X display when unfolded, giving it a much larger width than the Flip 4. However, the Fold is fractionally smaller than its predecessor, the Z Fold 3, as well as nearly 10 grams lighter, making it a bit more comfortable than the older model.

In terms of which foldable is more aesthetically pleasing, it really depends on your tastes. Some will undoubtedly prefer the sleek minimalism of the Z Flip 4, which folds in half and reduces in length to 71.9mm (2.83 inches), making it conveniently pocket-sized. On the other hand, the sheer size of the Z Fold 4 will also attract its own converts, who will prefer the ability to transform their smartphone into a tablet with an impressively vivid — and large — screen.

Speaking of displays, the Fold 4’s main 7.6-inch Dynamic AMOLED 2X display has a resolution of 2176 x 1812 pixels, working out at 372 pixels per inch. This contrasts with the Flip 4’s main display, which at 2640 x 1080 pixels, has a density of 426 ppi. Both of these displays support an adaptive refresh rate of up to 120Hz, making for some very smooth scrolling and animations.

So while the Z Fold 4 may be more immediately impressive due to the greater size of its unfolded (i.e. opened up) main display, the Z Flip 4 also has a supremely rich screen.

One difference, however, is that the Fold 4’s cover/front screen — a 6.2-inch Dynamic AMOLED 2X panel — is more impressive than its counterpart on the Flip 4, which happens to be a 1.9-inch Super AMOLED display with a resolution of only
260 x 512 pixels (compared to 2316 x 904 pixels for the Fold). As with the Z Flip 3, its functions will be relatively limited in comparison to those of the Fold 4’s cover screen, while it obviously isn’t as clear or as sharp. To be fair, this isn’t surprising, but it nonetheless marks the Z Flip 4 down on the display front in relation to the Z Fold 4.

Turning to durability, both devices are basically equal. They both feature an IPX8 rating for water resistance, as well as Armor Aluminum frames and Gorilla Glass Victus+ on their rears and displays. This makes them very robust, and while some would prefer the bigger dimensions of the Fold, the superior portability of the Flip rebalances things in this round, resulting in a tie.

Winner: Tie

Performance, battery life, and charging

Joe Maring/Digital Trends

Both foldables are powered by the Qualcomm Snapdragon 8+ Gen 1, a chip made using a 4nm manufacturing process, making it faster than previous generations. The Z Fold 4 packs 12GB of RAM, while the Z Flip 4 has 8GB. In theory, this would result in the Fold outperforming the Flip.

If you plan on doing a lot of multitasking and running multiple apps at once – something the Fold is naturally suited for — it’ll be the better choice here. Looking at storage, the Fold 4 offers 256GB of memory as standard and can be had with either 512GB or 1TB. The Flip 4, by contrast, starts with 128GB and can go up to 512GB.

Neither device has a slot for a microSD card. It’s disappointing, but with storage options going up to 512GB or 1TB, you probably wouldn’t notice the absence. On paper, the Z Fold looks like it offers longer battery life.

It has a 4,400mAh battery while the Z Flip has a 3,700mAh equivalent, yet in practice, you’re going to get a similar lifespan from both. That’s obviously because the Fold is considerably bigger than its stablemate, with two larger screens to feed. As such, you’re likely to need a recharge by the end of the day with both, although we’ll need to give each device a full review before coming to any firm conclusions.

This might suggest another tie, but with more RAM and more internal memory as standard, we’re going to give this round to the Z Fold 4, since it is a more capable machine than the Flip. Winner: Samsung Galaxy Z Fold 4

Camera

Andrew Martonik/Digital Trends

As with the previous generation, the Z Fold 4 and Z Flip 4 bear some noticeable differences in the camera department. As with its third generation, the Flip 4 has a 10MP selfie camera and a pair of 12MP lenses (wide and ultrawide) on the rear.

Meanwhile, the Fold has a triple-lens rear camera setup, with a 50MP main lens, a 12MP ultrawide, and a 10MP telephoto. You also get a 10MP selfie camera on its cover display, plus a 4MP camera under its main 7.6-inch display. The Fold’s triple-lens rear camera setup provides it with greater versatility, while its 50MP main lens offers an improvement over the 12MP main lens on the Fold 3.

It also offers a slight improvement over the 12MP main lens on Flip 4, which, if it’s like the Flip 3 (which also had a 12MP main lens), will take some excellent photos in good conditions, but may struggle with over-processing and saturation on occasion. On top of this, the 10MP telephoto lens on Fold 4 is genuinely usable, providing solid clarity and proving highly useful in situations where you can’t physically move close enough to your subject. While a full review will shed more light on just how exactly each phone performs in different situations, we’re fairly confident that the Fold’s wider assortment of lenses will make it a superior camera phone overall.

Winner: Samsung Galaxy Z Fold 4

Software and updates

Andrew Martonik/Digital Trends

Both phones run One UI 4.1, Samsung’s skin of Android 12. While there are a few subtle variations between each device’s implementation of One UI 4, the basic experience is essentially the same. That means you get a customizable and high-performing version of Android, replete with an enhanced privacy dashboard and a Stories feature in the Gallery app that compiles your best photos.

When it comes to updates, both devices are likely to be bumped up to Android 13 — and subsequent versions — around the same time. Like the Z Fold 3 and Z Flip 3 before them, we expect the Z Fold 4 and Z Flip 4 to receive Samsung’s standard update policy. That means four major Android updates and five years of security patches.

Winner: Tie

Special features

Joe Maring/Digital Trends

Aside from the obvious ability to fold, both the Fold 4 and the Flip 4 offer a range of special features. They each support 5G, while the Flip 4 offers Flex Mode, which enables hands-free photos and video streaming while the phone is folded shut. As for the Fold 4, it has been optimized even further for multitasking than the Fold 3.

It includes a new Windows-style taskbar at the bottom of its main display, making it more useful from a productivity standpoint. Users can also have three apps open and share the main screen at once, while a fourth app can be opened to float over them. The Fold 4 also works with the S Pen, turning it into a mobile powerhouse for drawing and note-taking.

All of this makes the Fold much more useful for professionals than the average smartphone, and this is why it takes a narrow win over the Z Flip 4 in this round. Winner: Samsung Galaxy Z Fold 4

Price and availability

The Samsung Galaxy Z Fold 4 is available to pre-order from Samsung, with prices starting at £1,800 for the base model, the same as with the Fold 3. It will be supported by all major carriers and should be sold by most major retailers once it’s released.

Also available to pre-order from Samsung, the Galaxy Z Flip 4 starts at £1,000, with prices rising for models with 256GB or 512GB of internal memory. It will also be supported by all major networks and sold widely by third-party retailers. Both phones are available for pre-order between August 10 and August 25, with regular sales beginning on August 26.

Overall winner: Samsung Galaxy Z Fold 4

Joe Maring/Digital Trends

Both foldables have their own respective merits, but the Galaxy Z Fold 4 edges the Z Flip 4 out by virtue of slightly better performance, more memory, and more multitasking potential.

It also arguably has a more impressive display, which, when unfolded/opened, effectively turns it into a tablet. It’s expensive, yes, but the sheer functionality provided by the Fold 4 is difficult to ignore. But that’s not to say the Flip 4 should be forgotten.

If you’re interested in a foldable but can’t stomach the Fold 4’s price (or simply don’t like its design), the Flip 4 is an excellent foldable alternative.

It’s not quite as functional or robust, but it’s absolutely worth keeping on your shortlist.
