The OnePlus 9 and 9 Pro are Android-based smartphones manufactured by OnePlus, unveiled on March 23, 2021. The phones feature upgraded cameras in partnership with Hasselblad.
Specifications.
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 3.0 storage. Both have 8 GB or 12 GB of RAM. Both have stereo speakers with active noise cancellation and no audio jack, akin to that of the previous generation OnePlus 8/8Pro and OnePlus 8T.
Design.
The OnePlus 9 and 9 Pro have similar designs to that of the previous generation OnePlus 8 and 8 Pro, with Gorilla Glass 5 on the front and back, and a “hole punch” style camera the upper left-hand corner. The 9's screen is flat with a plastic frame, 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. All colors ship with a glossy, Gorilla Glass back unlike the previous generation which had matte back options.
Display.
Both the OnePlus 9 and 9 Pro have AMOLED HDR10+ screen with a 120 Hz adaptive refresh rate (adaptive meaning the refresh rate is adjusted based on task). 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 10 billion colors, like its predecessor.
Both have an in-display optical fingerprint scanner and facial recognition as biometric options. The fingerprint sensor has been lowered more towards the bottom of the display from the ones in the OnePlus 8 series.
Camera.
The OnePlus 9 and 9 Pro both feature upgraded camera systems from their previous generations. The main upgrade is in the optics, which were co-developed with Hasselblad, specifically in the ultra-wide camera. Both phones now feature the same wide and ultra-wide cameras, which are a 23 mm, 48 MP, wide and a 14 mm, 50 MP, ultra-wide. The wide sensor is a 1/1.43" Sony IMX789 and the ultra-wide sensor is a 1/1.56" Sony IMX766.
The 9 Pro features an additional 77 mm, 8 MP, telephoto camera which uses the same sensor from the previous generation OnePlus 8 Pro.
Battery.
Both phones feature a 4500 mAh lithium polymer battery. This is an increase from the regular OnePlus 8, and a slight decrease for the 8 Pro. Both feature 65 W fast charging with the included USB-C power brick. The regular OnePlus 9 now features 15 W fast wireless charging, whereas with the previous series it was only included with the 8 Pro. The 9 Pro now features 50 W fast wireless charging with the purchase of a OnePlus-branded wireless charger. This is an increase from 30 W fast wireless charging in the previous generation.
Software.
Both phones ship with OxygenOS 11, based on Android 11.
