Reviews last updated: August 2026 · How we calculate this

What we like about OnePlus 9 5G (8GB + 128GB)

  • Blazing fast performance and speed, thanks to the Snapdragon 888 processor and 120Hz display.
  • Incredibly fast 65W wired charging (Warp Charge 65T) that can fully charge the phone in about 30 minutes, with the charger included in the box.
  • Impressive display quality, described as beautiful, crisp, and vibrant AMOLED with a smooth 120Hz refresh rate.
  • Good value for money, especially when purchased on sale, offering flagship-level specs at a competitive price point.
  • Clean and highly customizable software (OxygenOS 11), with minimal bloatware.
  • Solid battery life that typically lasts all day with average use.
  • High-quality main and ultra-wide cameras that produce detailed photos with good color accuracy in adequate lighting conditions.

What we don't like about OnePlus 9 5G (8GB + 128GB)

  • Inconsistent camera performance, particularly in low-light conditions, with some users finding the photo quality disappointing or 'fuzzy'.
  • Lack of Optical Image Stabilization (OIS) on the main camera, which affects clarity in low light and video stability.
  • Some users reported occasional overheating issues, especially during intensive use like filming in 4K/60fps or using GPS in the sun.
  • The phone has a plastic frame (mid-frame) which makes it feel less premium compared to other flagships with metal builds.
  • No official IP68 water resistance rating for the unlocked model.
  • Absence of a 3.5mm headphone jack and no expandable storage via a microSD card slot.
  • Potential long-term reliability concerns, with some users reporting hardware issues like screen green lines or motherboard failure after about a year of use.
  • Software updates (transition to ColorOS based OxygenOS 12/13) have been a drawback for some users, who found the new OS buggy and less appealing than the original OxygenOS 11.

Verdict

The OnePlus 9 (8GB + 128GB) offers high-end performance driven by the powerful Qualcomm Snapdragon 888 processor and smooth OxygenOS software. A key highlight is the excellent 6.55-inch Fluid AMOLED display with a 120Hz refresh rate for fluid visuals. Photography enthusiasts benefit from the capable Hasselblad-tuned triple-camera system, which captures vibrant and detailed photos. Pros also include very fast 65W wired charging capabilities. Potential drawbacks include the phone's plastic frame construction, the absence of a microSD card slot for expandable storage, and the lack of an official IP rating for water resistance on the standard model.
