What we don't like about Blackview Oscal Marine 2 (8GB + 256GB)

  • Battery charging can cause the phone to get notably hot, and charging speed is limited to 18W
  • Mediocre screen and audio quality, with some users reporting metallic-sounding speakers and a laggy display in certain apps
  • Front-facing 8MP camera performance is criticized as poor, with blurry selfies and ineffective AI enhancements
  • Uncertain software support with rare or non-existent long-term system updates
  • Inconsistent battery performance reports; while most praise it, some users felt it drained faster than expected for its 11,000mAh capacity
  • Software quirks such as clock and notification issues when the phone is locked or powered off

Verdict

The Blackview Oscal Marine 2 (8GB + 256GB) is a rugged smartphone running Android 15, primarily known for its exceptional durability and massive battery life. Key specs include a 6.56-inch HD+ 90Hz display, an octa-core Unisoc T615 processor, 8GB of RAM (expandable to 24GB via virtual RAM), and 256GB of internal storage (expandable up to 2TB). Pros are its robust build, which is IP68/IP69K and MIL-STD-810H certified for water, dust, and shock resistance, an enormous 11,000mAh battery with 18W fast charging and reverse wired charging capability, and useful features like NFC and quad-satellite navigation (GPS, GLONASS, Galileo, BeiDou). Cons are its substantial weight of 395g and lack of a 3.5mm headphone jack, which can be an inconvenience for users preferring wired audio accessories.
