The OnePlus 9, while more expensive, offers a better overall camera experience with more camera features like RAW Output and HDR Video, and it performs better in both photo and video quality. It also has a more powerful processor, more RAM, and comes with a high performance fast charger, which can be valuable if you prioritize performance and faster charging. On the other hand, the Samsung Galaxy A15 is less expensive, has longer battery life, but it has a lower camera quality and poorer performance. Additionally, while both have OLED screens, the OnePlus 9 has a higher refresh rate which can provide smoother visuals for gaming or scrolling. Both run Android but differ in body materials with the OnePlus having a glass back and the A15 a plastic one. If cost is a major factor for you and you're looking for longer battery life, the Galaxy A15 might suffice, but if you're willing to pay more for an overall better performance and camera, the OnePlus 9 would be the better choice.

"If you’re hunting for the best Android camera phone at this price, and one that doesn’t skimp on specs the OnePlus 9 is worth considering. Courtesy of a partnership with Hasselblad, the cameras offer better color correction, and both regular and ultra-wide photos look great. The OnePlus 9’s battery fully charges in under 30 minutes over a cable, and in 45 minutes using wireless charging. If you hate waiting for hours to charge your phone, you'll love the OnePlus 9."
