Top 10 World's Slimmest Phones in 2024

One feature of mobile phone design that often attracts attention is its thickness. Phones with a slim profile not only look aesthetically pleasing but also tend to be lighter. This reduction in weight enhances the ergonomic aspect, making the phone more comfortable to hold.

The preference for thin-bodied mobile phones has been around since the era of feature phones and continues to be a trend in the current smartphone era.

Here, Carisinyal presents a list of the world's thinnest mobile phones. Curious about which phones made the list? See the information below!

1. HONOR V Purse

HONOR Magic V Purse becomes one of the slimmest foldable smartphones available. Its sleek design measures just 4.3 mm when unfolded and 8.6 mm when folded.

Setting itself apart from typical foldable phones, the HONOR V Purse introduces a distinct design where it folds outward. This allows the screen to wrap around to the back of the phone, offering an extended display.

Drawing inspiration from the compact and portable nature of a woman's purse, often a staple at weddings, this phone is designed for convenience and style.

HONOR has equipped the phone with an innovative folding mechanism. This system includes a slender 1.2 mm spring and a tiny gear, only 1.7 mm in diameter to facilitate smooth folding.

In its design, the phone incorporates a concept called "Phy-Digital Fashion Statement." This blends the always-on display (AOD) feature with a stylish strap design, allowing the phone to be worn on the arm like a traditional purse. The display can also show decorative patterns reminiscent of those found on luxury bags.

The primary display is a 7.71-inch Foldable OLED panel, offering exceptional brightness of up to 1,600 nit. This ensures the screen remains clear even in bright sunlight.

The secondary screen is impressively large for a foldable phone, at 6.45 inches. It shares the same high brightness level and OLED technology as the main screen. Both screens offer a 90 Hz refresh rate for smoother visuals.

Despite its slender profile, the phone's weight is 214 grams. While this is on the heavier side for a phone touted as the "world's thinnest," it's still within the acceptable range for high-end smartphones.

The camera setup, while standard for premium phones, includes a 50 MP main camera and a 12 MP ultrawide sensor. Although it lacks a telephoto lens, the phone features a special Portrait Mode that toggles between 1x and 2x zoom.

As for its launch price in China on September 19, 2023, the HONOR V Purse was quite affordable at around 823 US dollars.

2. Honor Magic V2

HONOR Magic V2, formerly known as the world's thinnest foldable phone, has been outdone by the HONOR V Purse. First introduced to the Chinese market in July 2023, it achieved global availability in early 2024.

Sporting a vegan leather exterior, the HONOR Magic V2 presents a sleek form, measuring just 4.7 mm when unfolded and 9.9 mm when folded, with a weight of 231 grams. This makes it slightly lighter than the iPhone 14 Pro Max, yet heavier than the iPhone 15 Pro Max.

Compared to its forerunner, the HONOR Magic V, this model shows a remarkable decrease in thickness; the previous version was 6.7 mm thick when opened.

The HONOR Magic V2 features a sturdy, gearless unibody hinge crafted from titanium, engineered to endure up to 400,000 folding actions.

While it may not match the latest advancements in processor technology, running on the Snapdragon 8 Gen 2 instead of the more recent Snapdragon 8 Gen 3, it still holds its own among high-end smartphones.

A unique aspect of the HONOR Magic V2 is its compatibility with a stylus, applicable to both its primary and secondary displays. At its launch in China in July 2023, the starting price was set at 8.99 yuan, which is roughly equivalent to USD 1,299.

3. Honor Magic V2 RSR Porsche Design

The Porsche car-inspired variant of the HONOR Magic V2 shares the gearless titanium hinge of its regular counterpart, ensuring lightweight durability. This hinge has received SGS certification, indicating a high likelihood of enduring long-term use.

This foldable smartphone has a slim profile, measuring 9.9 mm when closed and thinning down to just 4.7 mm when open. It's also relatively lightweight at 234 grams.

Distinct from the standard HONOR Magic V2, this model, available exclusively in Agate Gray, sports a unique design. The camera module, with its tapered bottom edge, evokes the sporty elegance commonly associated with luxury cars.

The device offers a luxurious metal feel in hand. Its rear body is adorned with titanium alloy lettering and is covered in glass fibre material comparable in quality to that used in sports cars.

Enhanced durability is provided by the NanoCrystal Shield glass coating, reputed to be significantly more scratch-resistant and up to ten times more resistant to drops. Both the main and secondary displays, 7.92 inches and 6.43 inches respectively, feature 120 Hz OLED LTPO panels and support a rich palette of over 1.07 billion colors.

4. Honor Magic Vs2

HONOR Magic Vs2 features a titanium alloy hinge and a choice of two materials for its rear body: glass or eco-leather. It measures 5.1 mm in thickness when closed and 10.7 mm when opened.

Though it's slightly thicker than the Magic V2, the Vs2 is lighter, weighing just 229 grams, which is a decrease from the 231 grams of the previous Honor Magic Vs.

One notable enhancement is the display technology. The Magic Vs2 has upgraded to LTPO OLED panels for both its primary and secondary screens, replacing the standard OLED. This change enables more efficient battery usage by reducing the refresh rate to as low as 1 Hz when not displaying dynamic graphics.

In terms of screen size, the Magic Vs2 has seen a marginal increase, going from 7.9 inches on the Magic Vs to 7.92 inches. The front cover screen is 6.42 inches, having an impressive peak brightness of 2,500 nits.

Running on Android 13 with MagicOS 7.2, the HONOR Magic Vs2 provides enhanced features such as split-screen functionality and a hover mode. This makes the phone to be used in a 'laptop-like' position when half-open at a 90-degree angle or more.

The base model is equipped with 12 GB of RAM and 256 GB of storage and was launched in the Chinese market in October 2023 at a price of 6,999 yuan.

5. Huawei Mate X5

HUAWEI Mate X5 ranks among the thinnest mobile phones in the world, with a thickness of 5.3 mm when open and 11.1 mm when closed. This foldable phone features a vertical hinge and opens like a book and competes with models like the Samsung Galaxy Z Fold5.

Its design includes a glass front and two options for the rear body: glass or faux leather. The frame is made of aluminum, so it has a more durable and premium feel than polycarbonate plastic.

The phone is designed for stylus compatibility on both the front and main screens. The main screen is 7.85 inches, while the front screen measures 6.4 inches. However, both screens use standard OLED panels, not the more advanced LTPO technology, resulting in a less adaptable refresh rate compared to some competitors.

This smartphone has got IPX8 certification, ensuring it's resistant to water damage. A notable feature of this model is the inclusion of a Nano Memory slot, supporting up to 256 GB of additional storage. This is quite rare for high-end smartphones.

One drawback of the HUAWEI Mate X5 is its lack of Google Mobile Services, which limits its ability to run Android applications natively. The operating system for the Chinese release is HarmonyOS 4.0, while the European version uses EMUI.

6. Xiaomi Mix Fold 3

Xiaomi Mix Fold 3 was released in China in August 2023 and becomes the successor to the Xiaomi Mix Fold 2 from 2022. This foldable phone, which opens like a book, has a slim profile with a thickness of 5.3 mm when opened and 6.1 mm when closed.

Xiaomi attributes this slender design to a newly developed hinge system comprising 198 components. This innovative hinge allows the phone to be more compact, saving up to 17 percent of space compared to previous models.

Not only is it thin, but the phone also boasts a larger-than-average screen size, with the main display measuring 8.03 inches. The front screen is also sizeable at 6.56 inches, which is larger than many competitors.

The main display features LTPO OLED Plus technology, certified with Dolby Vision and HDR10+, and supports a peak brightness of 1,300 nits. The front screen is equipped with an AMOLED panel, reaching up to 2,600 nits in brightness and is protected by Gorilla Glass Victus 2, making it resistant to scratches and impacts.

One great aspect of this phone is its camera system, that is developed in collaboration with the renowned lens manufacturer, Leica. The device has two telephoto cameras, enhancing its capability for long-distance photography.

The first telephoto lens offers a 3.2x optical magnification, while the second is a "periscope" lens, supporting up to 5x optical magnification.

7. Huawei Mate X3

As a foldable phone, Huawei Mate X3 has got a sleek design with a thin body. When opened, its dimensions are 156.9 mm in length, 141.5 mm in width, and just 5.3 mm in thickness. However, when folded, the thickness increases to 11.08 mm.

This phone excels in its main screen size, featuring a 7.85-inch Foldable OLED panel. This large, tablet-like screen makes multitasking activities more manageable for users. The cover screen is also generously sized at 6.4 inches.

The display on this phone impresses with its vivid colors, supporting the DCi-P3 gamut and 1.07 billion colors. Powering the Huawei Mate X3 is the Snapdragon 8+ Gen 1, a top-tier SoC from 2022. This ensures the phone can effortlessly handle various tasks, including gaming and advanced editing.

In addition to its slim profile, the Huawei Mate X3 is also commendable for its durability. It has got an IPX8 certification, which means it can withstand being submerged in water up to 1.5 meters deep for 30 minutes.

8. Huawei Mate Xs

Huawei Mate Xs was launched in 2020 and quickly caught the public's eye as a standout foldable smartphone. It has a stylish and modern design, featuring plastic on the front and aluminum on the back and sides.

Weighing 300 grams, the Huawei Mate Xs is relatively light for a foldable smartphone. Its dimensions are 161.3 x 78.5 x 11 mm when folded and 161.3 x 146.2 x 5.4 mm when unfolded. Its unfolded thinness is particularly noteworthy, making it one of the thinnest mobile phones available.

The screen of the Huawei Mate Xs is a key highlight. It features an OLED display that folds into two sections. Opened up, the screen spans 8 inches with a resolution of 2200 x 2480 pixels. When folded, it measures 6.6 inches and maintains a resolution of 1148 x 2480 pixels.

Additionally, the Huawei Mate Xs supports a refresh rate of up to 120 Hz and a touch sampling rate of 240 Hz.

Internally, the Huawei Mate Xs is powered by the Kirin 990 5G chip, built with advanced 7 nm+ technology. It comes equipped with 8 GB of RAM and 512 GB of storage, and it supports NM memory cards up to 256 GB.

Camera-wise, the Huawei Mate Xs features a versatile setup with four rear cameras that also serve as front cameras. The rear camera array includes a 40 MP wide-angle lens, a 13 MP ultra-wide lens, an 8 MP telephoto lens, and a TOF 3D depth sensor. The front camera offers a 10.7 MP wide-angle resolution.

A significant limitation of the Huawei Mate Xs is the absence of Google services, such as the Google Play Store, Gmail, and Maps, due to U.S. government sanctions against the Chinese manufacturer. It runs on the Android 10 operating system with the EMUI 10 interface.

Users need to rely on alternative app stores like AppGallery or APKPure for app downloads, which can be inconvenient for those accustomed to Google services.

9. Xiaomi Mix Fold 2

Xiaomi Mix Fold 2 has gathered attention and comparisons to the Samsung Galaxy Z Fold due to its similar design. However, the Xiaomi Mix Fold 2 stands out with its slimmer build, measuring only 5.4 mm in thickness when unfolded and 11.2 mm when folded.

This screen is shielded by Schott UTG Glass and also achieves a peak brightness of 1300 nits and supports Dolby Vision and HDR10+, capable of displaying up to 1 billion colors.

10. Huawei Mate Xs 2

When unfolded, the Huawei Mate Xs 2 impresses with its ultra-slim profile, measuring just 5.4 mm in thickness. However, when folded, the thickness increases to 11.1 mm.

Beyond its remarkable thinness, the phone also owns a high-quality screen.
