The rugged smartphone market continues to grow, but few devices stand out as boldly as the FOSSiBOT F113. Designed for explorers, field workers, security personnel, and anyone who needs a phone that can survive extreme environments, the F113 combines huge battery life, long-range infrared night vision, and a durable industrial build. In this review, we break down its design, display, performance, cameras, battery life, and overall value to help you decide if this rugged 5G phone is right for you. Check our Full REVIEW.
Design & Durability
One of the first things you’ll notice about the FOSSiBOT F113 is its size and toughness. This is not a slim or lightweight smartphone—it’s built like a tank. The device comes with IP68 and IP69K ratings, meaning it’s fully waterproof, dustproof, and resistant to high-pressure water jets. It also carries MIL-STD-810H certification, ensuring it can survive drops, shocks, vibration, and harsh temperatures.
The corners are reinforced, the buttons are large and tactile, and the body has a rugged grip texture that helps prevent accidental slips. Whether you work outdoors, on construction sites, or in remote environments, the F113 feels like a device you can rely on.
While the rugged build is a major advantage, keep in mind that the phone is heavier and thicker than average smartphones. This is expected for a 20,000mAh rugged phone, but it’s worth noting for everyday pocket use.

Display Quality
The FOSSiBOT F113 features a 6.78-inch IPS display with a 120Hz refresh rate, giving you smooth animations, responsive scrolling, and an overall fluid user experience. The resolution is described as FHD+ / 2.4K, offering decent sharpness and clarity for watching videos, reading text, or browsing the web.
Colors are natural, brightness is sufficient for outdoor use, and the high refresh rate improves gaming and UI interactions. While it’s not an AMOLED display, the performance is strong for a rugged phone in this price range.
Performance & Hardware
Powered by the MediaTek Dimensity 7050 chipset, the F113 delivers reliable mid-range performance that is more than enough for daily tasks, GPS navigation, video streaming, communication apps, and moderate gaming.
Memory and storage are generous:
12GB RAM + up to 24GB extended RAM (36GB total)
256GB internal storage, plus microSD support
The Dimensity 7050 is efficient and handles multitasking well, making the phone suitable for demanding field use, long hours of navigation, and heavy app usage.
Camera System
The FOSSiBOT F113’s camera setup is one of its most unique selling points, especially for users who work in security or outdoor environments.
50MP Main Camera
The main camera captures good quality photos with solid detail and dynamic range. It performs well in daylight, with accurate colors and acceptable low-light results.
64MP Infrared Night Vision Camera (50m Range)
This is where the F113 becomes special.
The IR night vision camera can capture clear images in total darkness at up to 50 meters, making it a powerful tool for:
Wildlife viewing
Security patrol
Search & rescue
Nighttime inspections
Outdoor exploration
Unlike standard night mode in typical smartphones, this uses infrared technology, allowing you to see without visible light.
32MP Front Camera
The selfie camera is decent, providing clean and sharp images suitable for video calls and social media.
Video recording goes up to 4K, allowing for crisp footage in daylight conditions.
Battery Life & Charging
Battery life is arguably the biggest highlight of the F113.
It packs an enormous 20,000mAh battery, which is significantly larger than almost any smartphone on the market.
What this massive battery means for users:
Several days of normal use
Continuous GPS and outdoor use without power anxiety
Excellent standby time
Ability to use the phone as a backup power source with OTG
The phone supports 33W fast charging, which is decent, but buyers should understand that such a huge battery takes time to fully charge. Still, once topped up, the endurance is exceptional.
Audio, Flashlight & Extra Features
The F113 includes several practical features aimed at outdoor and professional use:
Extra-Loud Speaker (110 dB)
Useful for working in noisy environments or using the phone as a portable audio device outdoors.
1.5W Built-in Flashlight
This is not your typical smartphone flashlight.
It’s significantly brighter and can project light up to 50 meters, acting almost like a compact spotlight.
Extensive Connectivity
5G support
NFC
GPS, GLONASS, Galileo
Dual SIM
USB-C
These features make the F113 versatile for travel, navigation, and field operations.
Software
The FOSSiBOT F113 runs Android 13, giving users a clean and modern interface with access to all Google services. The system feels smooth, and the large amount of RAM helps keep apps running without slowdown.
Since FOSSiBOT is still a growing brand, major Android version updates may be limited compared to Samsung or Google devices, but the software experience itself is stable and user-friendly.
