Ulefone Armor 30

Design:
water resistance Waterproof Waterproof
weight 395 g 441 g
thickness 18.3 mm 18.5 mm
width 83.1 mm 86.8 mm
height 179.8 mm 182.8 mm
volume 273.427254 cm³ 293.54024 cm³
Ingress Protection (IP) rating IP68 IP69
has a rugged build
can be folded

Both phones share a waterproof rating and a non-folding, fixed-frame build, but the protection credentials diverge meaningfully. The Ulefone Armor 30 carries an IP69 rating, which adds resistance to high-pressure, high-temperature water jets on top of the submersion protection offered by IP68 — a relevant distinction for users in industrial, marine, or outdoor environments where a simple rinse or splash is not the only water risk. The Oscal Marine 2 stops at IP68, which covers prolonged submersion but would not withstand a pressure washer or powerful spray. Beyond that, only the Armor 30 is formally classified as having a rugged build, suggesting it is engineered with reinforced materials for drop and shock resistance — a spec the Marine 2 explicitly lacks.

On physical dimensions, the Marine 2 has a noticeable edge in portability. It weighs 395 g versus the Armor 30's 441 g — a 46 g difference that is perceptible in daily carry, especially for a device worn on a belt or held for extended periods. The Marine 2 is also marginally slimmer and narrower, resulting in a volume of ~273 cm³ compared to ~294 cm³ for the Armor 30, making it the more pocket-friendly of the two despite both being clearly large, utilitarian handsets.

The Armor 30 holds a clear overall advantage in this group for users who prioritize durability and field toughness: the superior IP69 rating and certified rugged construction put it in a higher protection tier. The Marine 2 trades some of that resilience for a lighter, more compact form factor, which may suit users who need basic waterproofing without the bulk of a full rugged device.

Display:
Display type LCD, IPS LCD, IPS
screen size 6.56" 6.95"
pixel density 269 ppi 396 ppi
resolution 720 x 1612 px 1080 x 2460 px
refresh rate 90Hz 120Hz
has branded damage-resistant glass
supports HDR10

Has a secondary screen
has a touch screen

The screen quality gap between these two devices is substantial. The Ulefone Armor 30 packs a 1080 x 2460 px resolution onto a 6.95″ panel, yielding a pixel density of 396 ppi — text and images will appear genuinely sharp. The Oscal Marine 2, by contrast, resolves at 720 x 1612 px across a 6.56″ screen, producing just 269 ppi. That difference is visible to the naked eye, particularly when reading small text, browsing the web, or viewing detailed photos. For a rugged device where the display may already be harder to read outdoors due to glare or a protective lens, starting with a lower-resolution panel compounds the usability challenge.

Refresh rate follows a similar pattern. The Armor 30's 120Hz panel delivers noticeably smoother scrolling and more responsive touch feedback compared to the Marine 2's 90Hz screen — a meaningful real-world difference for any user interacting with the device frequently. On common ground, both use LCD IPS technology and both feature branded damage-resistant glass, so neither has an advantage in panel type or scratch protection. Neither supports HDR10 or Dolby Vision, which is typical for this category.

One additional differentiator exclusive to the Armor 30 is a secondary screen, which can surface notifications or quick information without waking the main display — a practical feature for a field device. Taken together, the Armor 30 holds a decisive advantage in this group, outperforming the Marine 2 on resolution, pixel density, refresh rate, and screen size, while adding a secondary display the Marine 2 simply does not offer.

The chipset difference here is the defining story. The Ulefone Armor 30 runs on the MediaTek Helio G100, built on a modern 6 nm process, while the Oscal Marine 2 relies on the Unisoc T615, fabbed on an older 12 nm node. Process size matters practically in two ways: the Helio G100 can push more performance per watt, and its 5W TDP versus the T615's 10W TDP means the Armor 30 will run cooler and impose less drain on the battery under sustained load — a real advantage for a device used in demanding field conditions. The AnTuTu scores reflect this: ~412,000 for the Armor 30 against ~355,767 for the Marine 2, a gap of roughly 16% that translates to snappier app launches, smoother multitasking, and better headroom for more demanding applications.

Memory configuration widens the gap further. The Armor 30 ships with 12 GB RAM at 4266 MHz, compared to the Marine 2's 8 GB at 1866 MHz. The bandwidth difference — more than double on the Armor 30 — means data moves between RAM and the CPU/GPU far faster, which benefits everything from camera processing to running multiple apps simultaneously. Storage also favors the Armor 30 with 512 GB onboard versus 256 GB on the Marine 2, giving significantly more room for maps, media, and work files without relying on a memory card.

The GPU clock speed tells a similar story: 1000 MHz on the Armor 30 versus 850 MHz on the Marine 2, both using the Mali G57 — so the Armor 30 extracts meaningfully more graphics throughput from the same GPU architecture. Across every meaningful performance dimension in this group, the Armor 30 has a clear and consistent advantage, combining a more efficient chip, faster and more plentiful RAM, and double the storage capacity.

Camera hardware is where these two devices diverge most dramatically. The Ulefone Armor 30 fields a triple-lens rear system at 64, 50, and 50 MP, offering versatility across different shooting scenarios that a single lens simply cannot match. The Oscal Marine 2 counters with a solitary 16 MP main camera — lower resolution and no secondary or tertiary lenses, meaning users are locked into one focal perspective with no option to switch to a wide or telephoto view. For documentation, fieldwork, or any use case where capturing different angles or details matters, the multi-lens setup on the Armor 30 is a tangible practical advantage.

Video capability follows suit. The Armor 30 records at 4K (2160p) at 30 fps, while the Marine 2 tops out at 1080p at 30 fps. For users who need to capture high-resolution footage — whether for inspections, incident documentation, or content — that is a meaningful ceiling difference. The front camera gap is equally wide: 32 MP on the Armor 30 versus 8 MP on the Marine 2, which matters for video calls and self-documentation in professional contexts. The Armor 30 also doubles up with 2 flash LEDs compared to 1 on the Marine 2, providing better illumination in low-light scenarios.

The two phones share a largely identical feature set in terms of shooting modes — both support phase-detection autofocus, slow-motion, HDR mode, panorama, and manual controls for ISO, focus, and exposure. Neither shoots RAW. But shared features aside, the Armor 30 holds a decisive advantage in this group across every hardware dimension: more lenses, higher resolution on both front and rear, superior video recording, and better flash coverage.

This is a rare case of a complete tie. Both the Blackview Oscal Marine 2 and the Ulefone Armor 30 run Android 15 and share an identical feature set across every single spec in this group — without a single point of divergence. From privacy controls like location options, camera and microphone toggles, and app tracking blockers, to usability features like split-screen, Picture-in-Picture, dynamic theming, and offline voice recognition, the two devices are functionally equivalent on paper.

A few shared traits are worth highlighting for their practical value. Both support on-device machine learning and Live Text, meaning AI-assisted features like text recognition from images work locally without sending data to the cloud. Neither device receives direct OS updates from Google, which is typical for third-party Android manufacturers and means users depend on the respective brands to push timely patches — a consideration for long-term security. Neither blocks cross-site tracking, and neither supports Wi-Fi password sharing, gaps that are equally present on both sides.

With every spec in this group matching exactly, this is a complete tie — the operating system experience offers no basis for choosing one device over the other.

Battery:
battery power 11000 mAh 12800 mAh
has wireless charging
Supports fast charging
charging speed 18W 66W
comes with a charger
has a removable battery
has a battery level indicator
has a rechargeable battery

Both devices lean into the massive-battery philosophy that rugged phones are known for, but the Ulefone Armor 30 pushes further in every dimension. Its 12,800 mAh cell edges out the Oscal Marine 2's already generous 11,000 mAh — a 16% larger reserve that, all else being equal, translates to proportionally more screen-on time, standby duration, and headroom for power-hungry tasks like GPS navigation or hotspot use in the field. For a device category where multi-day battery life is often a core selling point, that gap is meaningful rather than marginal.

Charging speed is where the difference becomes especially stark. The Armor 30 supports 66W fast charging, which can realistically replenish even a battery this large in well under two hours. The Marine 2, by contrast, is capped at 18W — topping up an 11,000 mAh cell at that rate will take considerably longer, potentially three to four hours for a full charge. In practical terms, if a user needs a quick top-up before heading back out, the Armor 30 recovers far faster. On top of that, the Armor 30 adds wireless charging, a convenience the Marine 2 entirely lacks, allowing cable-free charging on compatible pads.

With a larger capacity, dramatically faster wired charging, and the addition of wireless charging, the Armor 30 wins this group decisively. The Marine 2's 11,000 mAh battery is far from inadequate in absolute terms, but it cannot match the Armor 30 on any of the three key battery metrics provided.

Audio:
has a socket for a 3.5 mm audio jack
has stereo speakers
has aptX
has LDAC
has aptX HD
has aptX Adaptive
has aptX Lossless
Has a radio

Audio is a short but clear-cut category. The Ulefone Armor 30 includes a 3.5 mm headphone jack, stereo speakers, and a built-in radio — three features the Oscal Marine 2 lacks entirely. For a rugged device likely used in environments where wired headsets or ear protection with audio pass-through are standard kit, the absence of a headphone jack on the Marine 2 is a genuine limitation. Wireless adapters add cost and introduce another potential point of failure in harsh conditions.

Stereo speakers matter too, particularly for hands-free use on a job site or outdoors where audio directionality and volume help with call clarity and media playback. A single mono speaker — which is what the Marine 2 is left with — simply cannot match the spatial presence of a stereo setup. The built-in radio on the Armor 30 is an added practical bonus for users in areas with limited data connectivity, though it will be less critical for many.

Neither device supports high-resolution Bluetooth audio codecs like aptX or LDAC, so wireless audio quality is on equal footing. But for everything involving wired audio or speaker output, the Armor 30 holds an unambiguous advantage — the Marine 2 offers no comparable features in this group.

Wireless connectivity is one of the more telling separators in this group. The Ulefone Armor 30 supports Wi-Fi 6E (802.11ax) alongside Wi-Fi 5 and Wi-Fi 4, while the Oscal Marine 2 tops out at Wi-Fi 5 (802.11ac). Wi-Fi 6E unlocks the 6 GHz band, delivering lower congestion and higher throughput in dense environments — relevant for worksites or facilities with many connected devices. The LTE download speed difference reinforces this: the Armor 30 reaches 650 Mbits/s versus 300 Mbits/s on the Marine 2, more than double the ceiling for data-intensive tasks like large file transfers or streaming. Upload speed is identical at 150 Mbits/s on both. The Armor 30 also carries a newer Bluetooth 5.4 versus 5.2 on the Marine 2, a modest but forward-looking advantage in connection stability and efficiency with compatible peripherals.

Sensor loadout adds another layer of differentiation. The Armor 30 includes a barometer and an infrared sensor, neither of which the Marine 2 has. A barometer is genuinely useful for outdoor and field users — it enables altitude estimation and weather trend monitoring. The infrared sensor allows the device to function as a universal remote, a secondary but convenient utility. Both phones share a solid common foundation: GPS, compass, gyroscope, accelerometer, NFC, fingerprint scanner, dual SIM, external memory slot, USB Type-C, and Galileo satellite support.

Neither device offers 5G, so cellular generational parity holds. But across Wi-Fi capability, download speed, Bluetooth version, and sensor breadth, the Armor 30 consistently pulls ahead — it is the more connected and more sensor-rich device in this group, with no spec where the Marine 2 holds an equivalent or superior position.

Miscellaneous:
has a video light
Has sapphire glass display
Has a curved display
Has an e-paper display

The Miscellaneous group offers no basis for differentiation whatsoever. Both the Blackview Oscal Marine 2 and the Ulefone Armor 30 share an identical profile across every spec here: both include a video light, and neither features sapphire glass, a curved display, or an e-paper display. This is a complete tie — no advantage exists for either device within this group.

Comparison Summary & Verdict

After examining every specification, the two phones serve distinct user profiles. The Blackview Oscal Marine 2 is the lighter, more compact option at 395 g with an 11,000 mAh battery, making it an appealing pick for users who want a manageable rugged handset without overspending on features they may not need. The Ulefone Armor 30, however, pulls ahead in almost every performance metric: its MediaTek Helio G100 chipset on a 6 nm node, 12 GB of RAM, a sharper 396 ppi 120Hz display, a triple 64+50+50 MP camera system, 66W fast charging, wireless charging, stereo speakers, a 3.5 mm audio jack, and Wi-Fi 6E support collectively justify its larger footprint. Buyers who prioritize raw capability and multimedia versatility will find the Ulefone Armor 30 the stronger all-round package.
