FOSSiBOT F113 Review 2025: Rugged Phone with 50m Night Vision & 20,000mAh Battery

The FOSSiBOT F113 is a rugged, adventure-focused 5G smartphone built for users who need durability, impressive battery life, and specialized imaging — especially at night. According to FOSSiBOT’s product page, it features a 64 MP long-range night vision camera, a massive 20,000 mAh battery, and a tough build (IP68 / IP69K, MIL-STD-810H).  It’s clearly aimed at outdoor enthusiasts, first responders, or anyone who wants a phone that can “see” in the dark.

What in Box:

• FOSSiBOT F113 Rugged Smartphone
• 33W Fast Charger
• USB Type-C Charging Cable
• Screwdriver and Screws
• Protective Wrist Strap
• User Manual and Warranty Card

Key Strengths

1. Night Vision Capability

• The standout feature is the 50-meter infrared (IR) night vision, which is quite rare in the smartphone world. FOSSiBOT claims this gives you real visibility into total darkness, allowing you to identify objects or people at a distance.
• This is not just a gimmick — according to FOSSiBOT, it’s a practical tool for search & rescue, wildlife observation, or security.

Verdict: If night-time visibility is important for you, this is a very compelling feature.

2. Battery Life

• The 20,000 mAh battery is enormous. On the product page, FOSSiBOT lists 33 W fast charging.
• Such a battery could easily support multi-day use in the field, which is ideal for camping, remote work, or extended outdoor trips.

Verdict: Excellent autonomy — probably one of the top rugged phones specifically for battery endurance.

3. Durability and Build

• It boasts IP68 and IP69K water/dust resistance plus MIL-STD-810H certification, meaning it can handle really rough environments.
• The screen uses Gorilla Glass 3, providing a level of scratch and drop resistance.
• The back reportedly has a liquid-silicone-like coating (per third-party write-ups) that improves grip and helps prevent slips.

Verdict: Very rugged and dependable — built to be dropped, splashed, and used in challenging environments.

4. Performance

• Powered by a MediaTek Dimensity 7050 (6 nm, 5G) according to FOSSiBOT.
• Memory is generous: “36 GB” is listed (12 GB base + up to 24 GB extended RAM), with 256 GB of storage.
• Such specs suggest it should handle everyday tasks, moderate multitasking, and probably even some heavier tasks, though it’s not meant to be a performance gaming beast.

Verdict: Strong for productivity and use in the field; not necessarily a flagship-tier gaming powerhouse, but solid.

5. Display

• The F113 uses a 6.78″ IPS display with 120 Hz refresh rate.
• FOSSiBOT describes it as “2.4K FHD+,” which implies a sharp and smooth viewing experience for a rugged device.
• The high refresh rate helps with fluid UI interactions, which is a plus in any phone — even in rugged phones.

Verdict: A great combo of size and smoothness; well-suited for both work and media consumption.

6. Audio / Flashlight

• It has 110 dB max loudspeaker output, which is very loud and useful in noisy or outdoor environments.
• A 1.5 W “super-bright” flashlight built in can project light up to 50 meters, which is a compelling utility tool.

Verdict: Very practical for safety, signaling, or night-time tasks.

7. Cameras

• Rear cameras: 50 MP main + 64 MP IR night vision.
• Front camera: 32 MP.
• According to some sources, the 50MP main sensor is a Sony IMX766, which is decent quality, though not top-flagship.
  • Video: Supports 4K recording.

Verdict: Very capable camera system, especially with the night vision — great for documentation, but not strictly for high-end photography.

Weaknesses / Drawbacks

1. Size and Weight
   According to third-party reviews, it’s a very large and heavy phone. One report notes a weight around 690g. (Greater Dutch) Such bulk might be inconvenient for everyday pocket carry or light use.
2. Charging Speed
   Although 33 W is decent, with a 20,000 mAh battery it will take a while to charge fully. The massive battery comes with a trade-off in recharge time.
3. Screen Resolution Trade-Offs
   While it’s a 120 Hz panel, some reports suggest the resolution isn’t as sharp or premium as high-end flagships — they describe it as “HD+” in some versions and note relatively thick bezels. (Note: there may be different spec variants or translation quirks.)
4. Niche Appeal
   The ultra-long range IR night vision and huge battery are not features everyone needs. If you mainly use your phone for calls, social media, or work in a normal environment, these extras might be overkill.
5. Availability / Shipping
   On the product page, there’s a note that says “Will not ship until …” for some regions, which might indicate limited stock or delayed shipments. (FOSSiBOT)
6. Grip & Form Factor
   While the protective materials help with grip, the large size could be unwieldy, and the aggressive rugged design may not appeal to those who prefer sleek, lightweight phones.

Who Is the FOSSiBOT F113 Best For?

• Outdoor adventurers — hikers, campers, and explorers who need a phone that can take a beating and help them navigate/observe at night.
• Search-and-rescue or security personnel — the 50 m IR night vision and bright flashlight are very useful in mission-critical scenarios.
• Remote workers / field operators — people working in construction, remote sites, or industrial settings where ruggedness and battery life are more important than slim design.
• Minimalists who want “one device” — if you need a phone + powerful flashlight + emergency tool + decent camera, this could cover a lot of bases.

Final Thoughts

The FOSSiBOT F113 is not a mainstream smartphone — and that’s exactly the point. It’s a specialist device. If you value ruggedness, extreme battery life, and the ability to see in total darkness, it’s one of the most interesting options on the market right now.

At its price point listed at $299.99, according to the official site, it offers very strong value for what you’re getting. Many traditional rugged phones or professional-grade gear could easily cost more for similar features, especially the night vision component.

Bottom line: If you need a phone that works like a survival tool and not just a communication device, the F113 is a standout. If you don’t need those rugged/survival features, you might be better served by a more conventional smartphone.
