10 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 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.

The IBOZOU Mini 4G is a tiny smartphone with a 3-inch HD screen, making it very compact and easy to carry—ideal for kids, students, or anyone wanting a light backup phone. Its battery is 2600mAh, which is decent for a small device and can comfortably support calls, messaging, and app use through a day of moderate use. It runs Android 12, allowing access to popular apps like Facebook, YouTube, and WhatsApp, which is a strong point for such a small phone. The phone has 3GB RAM and 32GB storage, enough for everyday apps and some media but not for heavy multitasking or large files. Camera quality is basic but functional for quick snapshots or video calls, fitting the phone’s child-friendly and portable design.

Build-wise, it’s compact and lightweight, though the plastic body and small screen might feel less premium compared to larger smartphones. It lacks a headphone jack, which may require wireless or USB-C headphones. Dual SIM support and unlocked 4G make it flexible for different networks, good for travel or kids needing a simple phone. While not suited for users needing top performance or advanced camera features, the IBOZOU Mini 4G delivers a solid, easy-to-use experience in a small, friendly package.
