Design and Build

The Tank 3 immediately stands out with its rugged and sturdy design. As mentioned in the introduction, this phone is not for the faint-hearted—it’s heavy. The textured carbon fiber back and metal body contribute to its robust build, making it a suitable companion for outdoor adventures. The inclusion of a water-resistant seal on the SIM tray enhances its durability, and the option for dual SIM plus expandable storage up to a whopping terabyte makes it versatile for various needs.

The front features a 6.8-inch display with a 120Hz refresh rate, providing a smooth visual experience. While the 100 Hertz 6.7-inch display may not compete with the latest flagships, it aligns well with the Tank 3’s price and purpose. The device’s overall bulk may deter users looking for a sleek and lightweight phone, but for those who prioritize durability and battery life, it’s a trade-off worth considering.

Hardware and Performance

Under the hood, the Tank 3 is equipped with a powerful 4-nanometer density 8200 chipset, making it a 5G-capable device. Running on Android 13, it comes with an impressive 32GB of RAM (16GB virtual and 16GB on board) and a massive 512GB of internal storage. This hardware configuration ensures smooth multitasking and ample space for apps, media, and files.

The standout feature of the Tank 3 is its colossal 23,800mAh battery, the largest in any smartphone known to date. Paired with a 120W fast charger, this device is a marathon runner in the smartphone world. The charging time indicates approximately 2.5 hours to go from a low battery level to a substantial charge. While the weight of the device is a notable downside, the extended battery life is undoubtedly a game-changer for users who prioritize longevity.

Camera Capabilities

The Tank 3 boasts an impressive camera setup, catering to both photography enthusiasts and those who prioritize functionality over camera specs. The rear camera array includes a 200MP AI camera, a 64MP super night vision camera, and an 8MP telephoto lens. The front camera stands at a formidable 50MP for high-quality selfies.

While the camera specifications are commendable, users might not be primarily drawn to the Tank 3 for its photography capabilities. Instead, it highlights the device’s robustness and outdoor features, putting the camera in the background. However, the provided camera samples and videos showcase the device’s ability to capture detailed and vivid images. Buy it here:

Connectivity-wise, the Tank 3 impresses with Wi-Fi 6 and Bluetooth 5.3, offering users the latest standards for seamless wireless communication.
