Hardware Both the OnePlus 9 and 9 Pro use the
Snapdragon 888 processor with the
Adreno 660 GPU, with either 128 or 256 GB of non-expandable
UFS 3.1 storage. Both have 8 GB or 12 GB of LPDDR5 RAM. Both have stereo speakers with
active noise cancellation and no
audio jack, similar to the previous generation
OnePlus 8/8Pro and
OnePlus 8T.
Design The OnePlus 9 and 9 Pro have similar designs to the previous generation OnePlus 8 and 8 Pro, with
Gorilla Glass 5 on the front and back, and a "hole punch"-style camera in the upper left-hand corner. The 9's screen is flat with a plastic frame and a 2.5D edge, while the 9 Pro's screen is curved with an aluminum frame. Only the 9 Pro has an official
IP Code (IP68); the regular OnePlus 9 is claimed by OnePlus to have water resistance, but has no official IP certification. The OnePlus 9 is available in three colors: Winter Mist, Arctic Sky, and Astral Black. The OnePlus 9 Pro is available in three different colors: Morning Mist, Pine Green, and Stellar Black.
Display Both the OnePlus 9 and 9 Pro have an
AMOLED HDR10+ screen with a 120 Hz refresh rate, with the 9 Pro featuring an adaptive refresh rate (meaning that the refresh rate is adjusted based on task) as it uses an
LTPO backplane. The OnePlus 9 has a 6.55 inch FHD+ display and a pixel density of 402 ppi, while the 9 Pro has a 6.7 inch QHD+ display and a pixel density of 525 ppi. The 9 Pro has 10-bit color depth, which allows it to display up to 1 billion colors, like its predecessor.
Camera The OnePlus 9 and 9 Pro both feature upgraded camera systems from their previous generations. The main upgrade is in the optics and color processing, which were co-developed with
Hasselblad, specifically in the ultra-wide camera. Both phones now feature the same ultra-wide cameras. The wide sensor is a 1/1.43" Sony IMX789 on the OnePlus 9 Pro and an IMX689 on the OnePlus 9 (as in the previous generation OnePlus 8 Pro) and the ultra-wide sensor is a 1/1.56" Sony IMX766.
