Test summary

Pros

  • Accurate target exposure in most photos and videos
  • Reliable autofocus for photos
  • Neutral and repeatable white balance in outdoor photos
  • Well-controlled noise in indoor and outdoor photos
  • Nice detail in ultra-wide photos and most videos
  • Pleasant color in most videos
  • Generally effective video stabilization

Cons

  • White balance errors and unnatural skin tones in indoor and low light photos and videos
  • Slightly limited dynamic range in high contrast photos
  • Visible noise in low light photos and videos

With an overall score of 115, the OnePlus 9 occupies a mid-table position in our Premium ranking. Compared to similarly priced devices, the OnePlus 9 is a little behind pace setters like the Apple iPhone 12 (122), Google Pixel 5 (120) and Xiaomi Mi 11 (120), achieving a score closer to the Samsung Galaxy S21 5G (116) and Oppo Find X3 Neo (115).

Capable stills with good video

The OnePlus 9 is capable of capturing great images with accurate target exposure and neutral white balance.

For stills, the OnePlus 9 offers similar exposure and color performance to last year’s OnePlus 8 Pro and achieves a respectable Photo score of 123. Target exposure is a strength, but dynamic range isn’t quite on par with the best Premium devices. Although white balance is generally neutral, skin tones are often inaccurate. Texture is acceptable, with only very fine details lost, noise is well-controlled outdoors, and although autofocus is reliable for sharp images, it can be a little slow in challenging light.

In the Zoom department, the OnePlus 9 scores a fairly low 46, which is predominantly due to the lack of a dedicated tele-lens and the resulting low-quality zoom images. The ultra-wide performs well though, with nicely detailed images if you can live with a bit of noise.

Effective stabilization, good detail, as well as generally accurate target exposure and color helped the OnePlus 9 on to a very respectable Video score of 104, too. Video autofocus and white balance can be a little unstable though.

Below you can find a detailed analysis and image samples for all Photo, Zoom, and Video sub-attributes, as well as comparisons with two of the OnePlus 9’s competitors, the Google Pixel 4a and the Xiaomi Mi 11, as well as the more expensive OnePlus 9 Pro.

Video

In our Video tests we analyze the same image quality attributes as for still images, such as exposure, color, texture or noise, but we also include such temporal aspects as speed, and smoothness and stability of exposure, white balance and autofocus transitions.

NOTE: The sample video clips in this section are best viewed at 4K resolution. 

The OnePlus 9 achieves a Video score of 104. A device’s overall Video score is derived from its performance and results across a range of attributes in the same way as the Photo score. In this section, we take a closer look at these sub-scores and compare video image quality against competitors.

For video artifacts, we check for the same kinds of artifacts mentioned in the Photo section, along with such video-specific artifacts as frame rate variation in different light conditions, judder effect, and moving artifacts (artifacts such as aliasing, color quantization, and flare can often be more intrusive when moving than in a still image).

This video still shows color quantization and judder effect artifacts are sometimes visible in videos.
