5 Best Mini Smartphones 2025 in the United States

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.

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 Pro is known as the smallest 4G smartphone in the world, making it an excellent choice for those who want a compact device. Its 2.45-inch screen is tiny compared to standard smartphones, which can be both a strength and a weakness depending on user preference. The small screen makes it highly portable but may not be ideal for extensive media consumption or typing.

It runs on Android 8.1 Oreo and is powered by a 1.2 GHz processor with 3GB of RAM, which should handle basic tasks adequately but might struggle with more demanding applications. The 32GB storage capacity is decent for a device of this size, though it may fill up quickly without options for substantial expansion. Battery life is another consideration; with a 950 mAh battery, it offers around 6 hours of talk time, which is relatively short, meaning it may need frequent charging, especially with regular use.

The camera quality is basic, suitable for quick snaps but not for high-quality photography. Build quality is solid, and the device is lightweight, weighing only 60.4 grams. Its design is minimalistic and straightforward. However, it only supports the T-Mobile network, limiting carrier flexibility. It does come with useful features like GPS and a pedometer, making it a good fit for basic fitness tracking and navigation. This phone lacks a charger in the box, so users need to use an existing one or purchase separately. The Jelly Pro is best suited for users who prioritize a compact size and portability over high performance and advanced features.
