Reviews last updated: August 2026 · How we calculate this

What we like about OnePlus 6 (8GB + 256GB)

  • Extremely fast and smooth performance powered by the Snapdragon 845 processor
  • Excellent value for money, often described as a 'flagship killer' at its price point
  • High-quality Optic AMOLED display with vibrant, punchy colors
  • Elegant and clean software experience with OxygenOS
  • Incredibly fast 'Dash' charging technology
  • Retention of the 3.5mm headphone jack and inclusion of a useful physical Alert Slider
  • Very fast and reliable fingerprint scanner and Face Unlock

What we don't like about OnePlus 6 (8GB + 256GB)

  • Lack of wireless charging despite the switch to a glass back
  • No official IP-rated water resistance (only splash-proof)
  • Single bottom-firing mono speaker instead of stereo speakers
  • No microSD card slot for expandable storage
  • Camera performance, while good, still trails behind top-tier flagships in low light
  • Poor vibration motor compared to other premium devices
  • Limited carrier compatibility in the US, specifically lacking support for Verizon and Sprint

Verdict

The OnePlus 6 (8GB + 256GB) is a 2018 flagship smartphone featuring a powerful Qualcomm Snapdragon 845 processor and Adreno 630 GPU, paired with a generous 8GB of RAM and 256GB of non-expandable storage. It boasts a large 6.28-inch Optic AMOLED display (1080 x 2280 resolution) and a premium all-glass design with Gorilla Glass 5 protection on the front and back. Key pros include exceptionally fast and smooth performance with the stock-like OxygenOS, a very fast fingerprint sensor and face unlock, Dash Charge fast charging for its 3300mAh battery, and the retention of a 3.5mm headphone jack. The dual rear camera system (16MP with OIS + 20MP) captures good photos in most conditions and supports 4K video at 60fps. Cons include a single, bottom-ported speaker, no official IP68 water resistance rating (only splash-proof), and the lack of a microSD card slot or wireless charging capabilities.
