Fossibot F113 smartphone features 64 MP infrared module that can cut through the darkness

Fossibot builds phones for people who push their devices to the limits, and the F113 takes that to the extreme. This thing weighs 500g (1.1lbs), with a reinforced plastic and rubber casing that can withstand drops from 2 meters and immersion in water up to 1.5 meters. Thanks to IP68/IP69K certifications for water and dust resistance and MIL-STD-810H for extreme conditions, you can take this device to construction sites, walk through mud or rain without breaking a sweat. The side-mounted strap lets you hold it like a tool, which is useful when you need both hands free but still want quick access.

The F113’s screen time starts with a 6.78-inch LCD panel with Full HD+ resolution of 1080 x 2400 pixels. The 120Hz refresh rate makes browsing maps and swiping between apps feel smooth, but peak brightness is only 480 nits, so you’ll need shade on the brightest days. Colors pop with a 1500:1 contrast ratio, and Corning Gorilla Glass 3 on the front provides further protection against scratches. The 32-megapixel selfie camera has a notch at the top and takes great photos in good light, but blurs details when shadows appear.

The power comes from a MediaTek Dimensity 7050 processor, an 8-core microprocessor made on 6 nm technology that combines efficiency and speed for daily workloads. With 12 GB of physical RAM and another 24 GB of storage, you can run many apps without any hiccups, from navigation software to video editing on the go. There’s 256GB of base storage and a microSD card that can be expanded up to 2TB, so you can store offline maps, high-resolution images and entire music collections. Android 15 comes standard with small additional apps on the home screen, making installation easy and updates available over the air.

The rear cameras form a triple operation, with a 50-megapixel primary sensor taking the lead for daytime photos, which look clean and natural when the settings are ideal. There’s also a 5-megapixel macro lens that lets you zoom in on very close details, such as leaf veins or small prints on a label, but it doesn’t work beyond a meter or two. But the real draw here is the 64-megapixel infrared module, which has a three-watt IR illuminator that emits light undetectable to the naked eye. When it’s pitch black, this system detects heat signatures from people or animals up to 50 meters away, rendering the entire scene in black and white with incredible clarity, allowing you to spot shapes and movements where a conventional phone would struggle to pick up anything. Then there’s the 160-lumen LED flashlight on the top edge, which provides a consistent 38-hour beam time for trails or work zones, and as you use it, the LED ring on the back of the phone flashes colors in tune with music or notifications for some fun.

The F113 is all about endurance; day after day it keeps going thanks to a 20,000 milliamp battery that outpaces most of its competitors by a country mile. Expect more than a week of mixed use, including calling, streaming and GPS tracking, before you need to plug it in. Charging is also fast; With 33 watts of wired power, half the pack can be topped up in about an hour, but there’s no wireless alternative, keeping things simple and cable-focused. You also receive a single bottom-firing speaker that produces 110 decibels, which is more than enough to cut through the noise on a construction site or fill a tent with music. Dual SIM support and 5G connectivity ensure you stay connected even if you’re in the middle of nowhere, while Wi-Fi 6 and Bluetooth 5.3 provide all the basic coverage.

The F113 costs $299.99 on the Fossibot website, up from $399.99, putting it well below the price of many other rugged phones that can’t compete with this model’s battery life and infrared capabilities.
