- Scenario 2: Casual User with Display Focus: Choose the OnePlus 9 Pro if you value the sharper display, wireless charging, audio features, and do not need peak performance or the newest OS.
- Scenario 3: Outdoor Photography & Videography: Choose the vivo iQOO 12 because of its much higher brightness for outdoor visibility, better telephoto and newer chipset.
My Choice
If I were to choose, I would pick the vivo iQOO 12. While the OnePlus 9 Pro has a sharper display, the iQOO 12 offers a far more compelling package for a modern smartphone user. The drastically improved performance with the Snapdragon 8 Gen 3 chipset is a game-changer for anyone who uses their phone heavily or enjoys gaming. The brighter display makes it more usable in everyday situations, and the faster charging and larger battery mean I won't be constantly worrying about power. The newer software will also mean longer support from the manufacturer which will keep the device relevant for longer. While I will be sacrificing the wireless charging, slightly less audio quality and a dedicated wide angle lens, the gains I get with the iQOO 12 outweigh these minor trade-offs. For me, the performance, battery and brighter display are non-negotiable features, making the vivo iQOO 12 the superior choice.
