This 5.5" all-terrain handset, which can be held in a single hand, combines an 8350 mAh battery with a compact build and IP68/IP69K plus MIL-STD-810H certifications, enduring drops, water and dust while keeping a moderate 291 g weight. Running pure and secure Android 15, the Unisoc SC9863A chipset works alongside 3 GB of RAM (expandable to 12 GB virtual) and 64GB of storage for smooth operation.
5.5" HD+ display
The HD+ (720 × 1440) IPS panel, shielded by Gorilla Glass 5, delivers 295 ppi, an 18:9 aspect ratio and Eye Care modes that lessen eyestrain over long sessions.
Extra-long battery life and fast charging
With 8350 mAh, you get up to 44 hours of talk time or 29 hours of continuous video; the bundled 10W charger tops up the battery swiftly so you can return to outdoor work.
Octa-core performance and expandable memory
The SC9863A (8 × 1.6 GHz) strikes a balance between efficiency and responsiveness for navigation, GPS and industrial tasks. The 64GB UFS can be expanded via microSD, while dynamic RAM adds up to 9 GB extra, handy for multitasking with maps and forms.
Versatile 13 MP + 8 MP cameras
The 13 MP f/2.0 main sensor captures sharp scenes even on construction sites or in the field; the 8 MP front camera ensures clear video calls, with anti-fingerprint protection on the glass.
Ruggedness and practical details
- IP68/IP69K and tested against submersion, dust and high-pressure jets.
- 17.8 mm chassis with double-injected reinforcements and three colours (Blaze Orange, Forest Green, Twilight Gray).
- Gorilla Glass 5, sealed ports and triple SIM + microSD slot.
Our expert's opinion
Within the "compact rugged" segment, the Fire 3 sets itself apart from the Oukitel WP20 (6,300 mAh, 4GB/32 GB, Android 12) and the Ulefone Armor X12 (4860 mAh, 3 GB/32 GB, Android 13 Go) by providing more battery, expandable memory and the latest Android version, while keeping a similar weight and an even target price. Next to the Fire 3 Pro/Ultra, it gives up graphics power but gains in lightness and cost. On the whole, it offers an excellent quality-performance ratio for professionals needing a rugged, compact device with long battery life without overspending.
