Folding smartphones have come a long way since the original Samsung Galaxy Fold came out in 2019. They’re smaller, more durable and, even if they aren’t exactly the most budget-friendly phones, they’re more affordable now, too. Whereas you may not have considered a foldable phone as your daily driver five years ago, they’re much more viable options today — and you have many more to choose from. If you’ve been toying with the idea of switching to a folding phone, or you’re ready to upgrade the foldable you already have, we at Engadget can help with your decision-making process. We've spent hundreds of hours and many days testing and reviewing the best foldable phones on the market right now — here's everything you need to know before picking one up.

Note: For this guide, we’re focusing on devices that are widely available in North America and Europe. That’s because while there are even more options for people who live in Asia (especially China), they are often difficult to buy from abroad and may not support your local carriers.

How we test foldable smartphones

When evaluating foldables, we consider the same general criteria as we do when we’re judging the best smartphones. Devices need to have good battery life (at least a full day’s use), bright displays (peaks of at least 1,000 nits), sharp cameras and responsive performance. That said, foldable phones come in different shapes (and sizes); there are varying designs that may appeal to different types of people.

For those who prefer more compact and stylish devices, flip-style foldables resemble old-school namesakes but with flexible interior displays (typically six to seven inches diagonally) and smaller exterior screens. Alternatively, for power users and people who want to maximize mobile productivity, there are larger book-style foldables (with seven to eight-inch main displays) that can transform from a candy bar-style phone to essentially a small tablet when opened.

Are foldable phones worth it? A note on durability

Aside from their displays, the biggest difference between foldable phones and more traditional handsets is durability. That’s because while some models like the Pixel Fold and Samsung’s Galaxy Z line offer IPX8 water resistance (which is good for submersions of up to five feet for 30 minutes), their flexible screens – which are largely made from plastic – present some unique challenges.

Most foldables come with factory-installed screen protectors. However, unlike regular phones, users are instructed not to remove them without assistance from approved service centers. Thankfully, Samsung does offer one free screen protector replacement for its foldables, while Google charges between $29 and $129 depending on the warranty status of your device. That said, while we can’t do long-term testing for every foldable phone on the market, after personally using the Galaxy Z Fold 3 and Galaxy Z Fold 4 each for a year, I’ve found that Samsung’s pre-installed screen protector tends to start bubbling nine to 12 months after purchase. So you’ll probably want to factor in that your foldable may need some sort of servicing after about a year unless you plan on removing the screen protector entirely (which is possible, but goes against most manufacturers' instructions).

Furthermore, foldable phone owners need to be mindful about keeping sharp objects away from their flexible displays, as rocks, keys or even pressing down very hard with a fingernail can leave permanent marks. In the event that you need to get a flexible screen serviced, you’re potentially facing a much higher repair bill when compared to a typical phone (up to $500 or more depending on the model and the severity of the damage). In short, while the ruggedness of foldable phones has improved a lot, they're still more delicate than traditional handsets, which is something you need to account for.

Intel's relatively new Foundry division — formerly known as Intel Foundry Services until earlier today — has just landed a notable order from a big name. According to Bloomberg and The Wall Street Journal, Microsoft CEO Satya Nadella announced that his company will be tapping into Intel's latest 18A (1.8nm) fabrication process for an upcoming in-house chip design. But given Intel's process roadmap, this means we likely won't be seeing Microsoft's new chip until 2025.

While neither company disclosed the nature of said silicon, Microsoft did unveil its custom-made Azure Maia AI Accelerator and Azure Cobalt 100 CPU server chips last November, with an expected rollout some time "early" this year to bolster its own AI services. The Cobalt 100 is based on Arm architecture, and it just so happens that Intel has been optimizing its 18A process for Arm designs since April last year (it even became an Arm investor later), so there's a good chance that this collaboration may lead to the next-gen Cobalt CPU.

In addition to the usual efficiency improvements as node size decreases, Intel 18A also offers "the industry's first backside power solution" which, according to IEEE's Spectrum, separates the power interconnect layer from the data interconnect layer at the top, and moves the former to beneath the silicon substrate — as implied by the name. This apparently allows for improved voltage regulation and lower resistance, which in turn enable faster logic and lower power consumption, especially when applied to 3D stacking.

Intel

In Intel's Q4 earnings call, CEO Pat Gelsinger confirmed that "18A is expected to achieve manufacturing readiness in second half '24." Given that Intel's very own 18A-based processors — "Clearwater Forest" for servers and "Panther Lake" for clients — won't arrive until 2025, chances are it'll be a similar time frame for Microsoft's next chip.

At Intel's event earlier today, the exec shared an extended Intel Foundry process technology roadmap, which features a new 14A (1.4nm) node enabled by ASML's "High-NA EUV" (high-numerical aperture extreme ultraviolet) lithography system. According to AnandTech, this 14A leap may help Intel play catchup after its late EUV adoption for its Intel 4 (7nm) node, though risk production won't take place until the end of 2026.

Intel Foundry is the brainchild of Gelsinger, who launched this department right after he assumed the CEO role in February 2021, as part of his ambitious plan to put Intel up against the likes of TSMC and Samsung in the contract chip-making market. Before Microsoft, Intel Foundry's list of clients already include MediaTek, Qualcomm and Amazon. The company still aims to become "the second largest external foundry by 2030" in terms of manufacturing revenue, which it believes is achievable as early as this year.

Following its autonomous food delivery launch in Miami and Fairfax, Virginia, Uber Eats will soon be offering the same robotic service in Japan — its first outside the US. It is once again collaborating with Google alum startup Cartken, with local compliance help from Mitsubishi Electric, to bring a fleet of Model C sidewalk delivery robots to select areas in Tokyo in March. Uber Eats Japan CEO Shintaro Nakagawa says the autonomous delivery service will solve the local labor shortage issue, while complementing the existing human delivery methods "by bicycle, motorbike, light cargo, and on foot."

Cartken's six-wheeled Model C uses six cameras and advanced AI models for autonomous driving plus obstacle detection, and remote control mode is available when needed. With guidance from Mitsubishi, the robot has been modified to suit local needs in Japan. For one, its speed is capped at 5.4 km/h or about 3.36 mph as per local regulation, which is a lot slower than the 6 mph top speed it's actually capable of. The loading capacity has also been reduced from 1.5 cubic feet to about 0.95 cubic feet (27 liters), likely due to the extra thermal insulation in the compartment. Uber Eats adds that for the sake of privacy, people's faces are automatically masked in footage captured by the robots.

While this is Uber Eats' robotic delivery debut in Japan, Cartken already has a presence there thanks to Mitsubishi. Since early 2022, the duo has worked with Starbucks, local e-commerce giant Rakuten and supermarket chain Seiyu in some parts of Japan. In the US, Cartken also has a partnership with Grubhub to provide autonomous food delivery service on college campuses, including the Ohio State University and the University of Arizona.

Even though Uber Eats has yet to share which Tokyo restaurants will be tapping into its robotic delivery service, it should have no problem seeking partnership given Cartken's prior local experience. That said, I highly doubt that the pair would risk trialing their robots through a crowd of drunkards in Shibuya just yet.

Instant messaging app Signal is best known for its privacy-related settings, though with phone numbers being the heart of the platform since its inception, there was no way to fully hide your own number until now. Earlier today, Signal announced that you'll soon be able to create a unique username (not to be mistaken with your profile name), which you can share with others via a link or QR code — as opposed to sharing your number. You'll be able to change your unique username as often as you want, but it needs to contain two or more numbers at the end, as part of Signal's anti-spoofing efforts. You can even delete your username entirely, as it is an optional feature.

Naturally, you'll still need a phone number to sign up for Signal, but note that with the new default, your number will no longer be visible to everyone (you can change this setting manually, if needed). There will also be a new option which prevents people from finding you by your number; they will need to have your exact unique username to do so. In other words, people who already have your number won't necessarily know that you are also on Signal, which is a good thing if you prefer to stay anonymous in this platform's public groups.

As is the case with any new feature, the likes of spammers and scammers will eventually find a way to abuse usernames, as you won't be able to verify their numbers instantly. Pro tip: when you see new contacts that appear to be your acquaintances, always double check with them through other means — preferably in person, or at least via a phone call. You may look out for these new Signal features in a few weeks' time, or you can get an early taste in the beta release.

When Honor's Magic V2 first showed up some seven months ago, we were left impressed with its sub-1cm folded thickness. The company has since picked up where Huawei left off and joined forces with Porsche Design, with the first result being a special edition foldable phone, the "Magic V2 RSR" ("RSR" stands for "RennSport Rennwagen," which translates to "racing sport racing car"). Porsche fans may recognize several attributes here that pay homage to the automotive brand, including the iconic agate gray along with a flyline running down the middle of the body — supposedly resembling the Porsche 911's hood. The rear camera island has also been upgraded with a dark titanium frame to go with its bolder trapezoidal redesign.

The Magic V2 RSR retains the same dimensions, measuring 9.9mm thick when folded and 4.7mm when opened, ensuring it remains the world's thinnest foldable phone. The extra decoration adds 3 grams over the base model, reaching 234 grams (about 8.25 oz) which still beats the likes of the OnePlus Open, Samsung's Galaxy Z Fold 5 and Google's Pixel Fold, largely thanks to Honor's mix of titanium alloy and proprietary steel in its hinge design — this is apparently certified to last for at least 400,000 folds. As a bonus, the Magic V2 line's 5,000mAh battery capacity is larger than the competition, thanks to its more energy-dense silicon-carbon cells. The trade-off here is the missing wireless charging, but you do get 66W of wired fast charging, which takes around 50 minutes to go from zero to 100 percent.

The Magic V2 RSR is still powered by Qualcomm's Snapdragon 8 Gen 2 processor, but with storage option limited to just 1TB to go with the 16GB of RAM. The rest of the spec sheet is identical for both Magic V2 variants. For displays, you get a 7.92-inch 2,344 x 2,156 foldable OLED screen (with a barely-noticeable crease) and a 6.43-inch 2,376 x 1,060 exterior OLED display, with their brightness going up to 1,600 nits and 2,500 nits, respectively. For audio, this Android phone comes equipped with "IMAX Enhanced" stereo speakers, whereas phone calls leverage the device's three-mic system for better voice reception. As is the case with most foldables, the fingerprint reader is integrated into the side-mounted power button.

The rear "Falcon Camera System" consists of a 50-megapixel main sensor, a 50-megapixel ultra-wide shooter and a 20-megapixel telephoto camera (2.5x zoom), whereas a 16-megapixel punch-hole selfie camera sits at the top of both screens. Both the rear and front cameras support up to 4K resolution for video recording.

It should come as no surprise that the Magic V2 RSR boxset packs some extra goodies, namely an active stylus, its own carrying case and a spare 66W charger. The special protection case is wrapped in a stitched dark gray vegan leather, though compared to the normal version, it's missing out on a kickstand — a feature I struggle to live without when it comes to foldable phones.

Like the base model, the Magic V2 RSR will also be headed to global markets, though the prices are under wraps until MWC later this month. For reference, the Magic V2 RSR retails for 15,999 yuan or about $2,220 in China, but expect a huge bump for international pricing. The regular Magic V2 — only available in 512GB flavor for international markets — is priced at £1,700 ($2,140) in the UK and €1,999 ($2,150) in Europe, but the China version and Hong Kong version (also international firmware) cost around $1,400 only. It's no wonder that some savvy consumers would rather import smartphones from overseas, despite the lack of local warranty services.
