Top 10 World's Slimmest Phones in 2025
One aspect of mobile phone design that often gets attention is its thickness. A slim phone not only looks sleek but also tends to be lighter to make it more comfortable to hold. The preference for thin phones isn't new; it's been around since the days of feature phones and continues to be a trend with today’s smartphones.
Here, Carisinyal presents a list of the world's thinnest phones. Curious to know which ones made the cut? Take a look at the details 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. vivo X Fold3

The vivo X Fold3 is an impressive foldable phone with a lot to offer. When unfolded, it’s incredibly slim at just 4.7 mm. The design is minimalist, featuring strong hinges and a carbon fiber frame for durability.
The main screen is a large 8.03-inch Foldable LTPO AMOLED with a sharp resolution of 2200 x 2480 pixels, while the secondary screen is a 6.53-inch AMOLED with a resolution of 1172 x 2748 pixels.
Both screens support HDR10+ and Dolby Vision that can reach up to 4500 nits of brightness, making them perfect for outdoor use. With a 120 Hz refresh rate, the screen movement is smooth and fluid.
The stereo speakers deliver loud and clear sound. Powered by the Snapdragon 8 Gen 2, this phone handles heavy multitasking and gaming with ease. It offers up to 16 GB of LPDDR5x RAM and up to 1 TB of UFS 4.0 internal storage, ensuring you have plenty of space and speed for your apps and files.
The camera setup includes a 50 MP triple lens system, developed in collaboration with ZEISS, featuring optical image stabilization (OIS) on the main camera, 2x optical zoom on the telephoto lens, and a 119-degree ultrawide field of view.
You can record videos in up to 8K at 30 FPS or 4K at 60 FPS, with gyro-EIS providing added stabilization. The phone also includes two 32 MP front cameras—one on the main screen and one on the cover. This is great to take selfies from any angle. Connectivity options are extensive, with support for WiFi 7, infrared, NFC, USB OTG, and a hardware gyro.
However, there are a few drawbacks to consider. When folded, the thickness increases to 10.2 mm, and at 219 grams, it can feel a bit heavy and uncomfortable to hold with one hand.
Additionally, the phone doesn’t include built-in protection for the body or screen, which could be a concern for durability. Lastly, the front camera is limited to recording video at 1080p at 30 FPS, which might not meet the expectations of those who prioritize high-quality video.
3. 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.
4. Honor Magic V2 RSR Porsche Design

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.

This three-camera system, developed in collaboration with ZEISS, allows for video recording in up to 8K at 30 FPS, with gyro-EIS for added stability. The device also includes two 32 MP front cameras, one on the main screen and one on the secondary screen, ensuring high-quality selfies.
For the connectivity, it includes WiFi 7, infrared, NFC, and USB OTG. The device also features advanced sensors, such as a hardware gyro and dual-screen fingerprint sensors on both the main and outer screens.
The 5700 mAh battery, made from Silicon Carbide, supports 100W fast charging, 50W wireless charging, and even reverse wireless charging, providing flexibility in power management.
However, when folded, the phone’s thickness increases to 11.2 mm, and its weight of 236 grams can make one-handed use uncomfortable. Also, screen protection is only applied to the outer screen, leaving the inner display more vulnerable.

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.

9. 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 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.
In conclusion, these are some of the world's thinnest and most advanced mobile phones. They are ideal choices for anyone seeking a combination of aesthetic elegance and cutting-edge technology in a smartphone.
