10 Best Mini Smartphones 2025 in the United States

The IBOZOU Mini 4G Unlocked Smartphone is a compact device with a 3-inch HD screen, making it highly portable and easy to carry. This mini smartphone is particularly suitable for kids or as a backup phone due to its dual SIM capability and lightweight design. With a 2600mAh battery, it offers decent battery life for everyday tasks.

The phone runs on Android 12.0, providing access to a wide range of apps from the Google Play Store, such as Facebook, YouTube, Instagram, and more. It supports voice calls, video calls, GPS navigation, and other essential functions, making it a versatile device for its size. However, the 3-inch screen might be too small for users who prefer larger displays for media consumption or extensive typing.

Performance-wise, it features a quad-core processor and 3GB of RAM, which should be sufficient for basic tasks but may struggle with more demanding applications. The build quality and design are aimed at children, with a cute and sturdy feel, available in pink, black, and purple. This phone is best suited for children, students, or users needing a compact secondary phone for light use during activities like cycling, hiking, or traveling.

The Unihertz Jelly Star is marketed as the world's smallest 4G Android smartphone, offering a unique blend of compact size and modern features. Its standout characteristic is the 3-inch display, which is incredibly small compared to most smartphones today. This makes it an interesting choice for those who prefer a device that can easily fit in a pocket or be used one-handed. The transparent design with dynamic LED notifications adds a cool factor, appealing to users looking for something visually distinct.

One of its key strengths is the camera quality, featuring a 48 MP rear camera, which is quite impressive for a smartphone of its size. It also boasts a powerful Octa-Core MediaTek Helio G99 processor, combined with 8GB of RAM, ensuring that it can handle everyday tasks smoothly. With 256GB of storage, users won't have to worry much about running out of space.

However, there are notable drawbacks. The 2000 mAh battery might not last a full day with heavy usage, especially given the demands of modern apps. The resolution of 854 x 480 pixels also falls short of current standards, which may disappoint users who prioritize visual clarity. Additionally, it's essential to note that the Jelly Star only supports T-Mobile and Verizon in the US, which may limit its appeal to users on other carriers. The Jelly Star runs on Android 13, which is a plus for those looking for a more recent operating system. It includes features like NFC, dual SIM support, and a fingerprint unlock, adding convenience for everyday use.

The Unihertz Jelly Star is a fun and functional mini-smartphone that caters primarily to individuals looking for a compact device with decent performance and unique design. However, potential buyers should consider its limitations in battery life and display quality before making a decision.

The Unihertz Jelly 2 is an intriguing option for those seeking an ultra-compact smartphone. With a screen size of just 3 inches, it is marketed as the world's smallest Android 11 smartphone, making it perfect for users who prioritize portability. The device is lightweight at 110 grams and fits comfortably into a pocket or bag. Its build quality is decent, and it comes in a stylish dark green finish, appealing to those who appreciate unique designs.

In terms of performance, the Jelly 2 is powered by a 2 GHz CPU and has 6GB of RAM, which is relatively good for everyday tasks like browsing, messaging, and running basic apps. However, with a resolution of 480 x 854, the display may not provide the sharpest visuals, especially when compared to larger smartphones. The camera quality, while adequate for casual photography, is limited compared to higher-end models.

Battery life, at 2000 mAh, should be sufficient for light users, but heavy usage could lead to more frequent charging. It supports 4G connectivity and is compatible with major US carriers like T-Mobile, Verizon, and AT&T, though setup may require additional steps for certain networks. This limited compatibility could be a drawback for users who rely on other carriers. The Jelly 2 runs on Android 11 and includes features such as NFC, GPS, and Bluetooth, which enhance its functionality. The small screen size may not suit everyone, especially for those who enjoy multimedia consumption or gaming, where a larger display typically enhances the experience.

The Unihertz Jelly 2 is ideal for users who need a highly portable device and are looking for basic smartphone capabilities. It's a solid choice for minimalists or as a secondary phone, but its limitations in display quality and battery life may not meet the needs of those seeking a primary smartphone for extensive use.
