- Oscal Tank 1 combines extreme endurance and technical claims that seem strange
- Oscal’s “48GB RAM” figure combines real memory with virtual expansion storage
- Powered by Dimensity 7050 processor and runs DokeOS 4.2 built on Android 15
The Oscal Tank 1 is a rugged smartphone designed for extreme conditions, combining a massive 20,000 mAh battery, reinforced construction and ambitious performance.
Designed for users who work or travel in demanding environments, it offers 5G connectivity, a triple-camera system with night vision, and a dual-screen layout designed for outdoor visibility.
Yet its most discussed feature is the claim of “48GB of RAM”, a figure that may not fully reflect the physical hardware.
Designed for demanding environments
The Oscal Tank 1 comes with a 6.78-inch 2.4K display rated at 700 nits and 120 Hz, backed by a smaller rear screen for quick updates.
The high refresh rate and brightness suggest that the display is designed to provide clear outdoor visibility, a necessary feature for users working in harsh environments.
Under the hood, this device is powered by MediaTek Dimensity 7050 processor and runs DokeOS 4.2 based on Android 15.
It also integrates AI tools for content creation and image processing, features that could prove useful for users who need to edit visuals or analyze data directly in the field.
The three-camera array includes 64MP, 50MP, and 20MP sensors, with night vision support for low-light environments.
On paper, this combination promises versatility in all lighting conditions, but true performance will depend on how its processing software works.
Oscal claims the Tank 1 can last up to 1,080 hours of standby time or several days of active use, backed by 55W fast charging designed to provide quick recharges.
Such endurance could benefit field workers or travelers far from power sources, but it raises practical issues regarding phone bulk and heat management.
Housing such a large cell could make the device heavier than standard models, putting it closer to a rugged tablet than the best smartphone for everyday use.
The device’s most controversial claim is its “48GB of LPDDR5 RAM,” as it appears that only part of that figure represents actual hardware, with the rest achieved through virtual expansion using some of the internal storage.
This technique can help manage multiple applications at once, but cannot replicate the speed or stability of real RAM.
Without clear communication from Oscal, the actual memory configuration remains uncertain.
The company touts the Tank 1 as being able to survive harsh weather, deep water and harsh impacts. It lists IP68 and IP69K ratings, MIL-STD-810H certification, and tolerance for drops from ten meters, submersion from two meters, and pressure up to 1,200 kilograms.
The phone would also work in temperatures between -50°C and 70°C.
The Oscal Tank 1 is scheduled for release on October 20. Sales will begin on Amazon, and its price is €379.99 for the 12GB + 256GB model and €399.99 for the 16GB + 512GB variant.
The specs look promising, but until the device is independently tested, it remains unclear whether this rugged smartphone can actually deliver on its promises.
