OnePlus 9 Summary
The OnePlus 9 still feels solidly built and the plastic frame does look like metal, even though it’s not. The alert slider and buttons have good tactile feedback, similar to the ones on the 9 Pro. The OnePlus 9 has a similar 6.55-inch AMOLED display as the 8T. Software is taken care of by OxygenOS 11, which is based on Android 11.
Performance has been very solid right from the get go thanks to the Qualcomm Snapdraogn 888. The display is excellent – colours are vibrant, brightness is very good, and viewing angles are more than satisfactory. The OnePlus 9 delivers very good battery life; a bit better than the 9 Pro in fact, in my opinion.
The cameras on the OnePlus 9 are a big upgrade compared to its predecessor’s mainly due to better sensors. The selfie camera is the same one used for the OnePlus 9 Pro, and it’s decent but not great. The OnePlus 9 is a good smartphone in its own right, but hard to recommend when you have the Samsung Galaxy S20 FE 5G and OnePlus 8 Pro selling for around the same price.
