My Choice
If I were choosing between these two devices, I would choose the OnePlus 9.
Here's why:
- Overall User Experience: While the Infinix has a bigger battery, the OnePlus 9 offers a drastically better user experience in almost every other aspect. I value a smooth, responsive phone with a great display, excellent camera, and fast charging. The difference in performance and visual quality is vast, and those are the things I value the most. The increase in the cost associated with this device is one that I am okay with paying for.
- Future-Proofing: The OnePlus 9 has a more powerful chipset, more RAM, and is more likely to receive software updates longer which is important for future use. I tend to keep my devices for several years, and the OnePlus 9's hardware is far better suited to handle future updates and apps.
- Camera Quality: As someone who enjoys taking photos and videos, the camera system on the OnePlus 9 is a significant draw. The difference between the two cameras is substantial.
- Daily Use: The faster charging and superior display would make my daily usage more enjoyable. I frequently check my phone outdoors where the OnePlus 9 will be significantly more visible.
While the longer battery life of the Infinix Hot 12 Play is appealing, it does not outweigh the performance, display, camera, and overall user experience the OnePlus 9 offers. The Infinix is a very low end device while the OnePlus 9 is a flagship, and they are not really comparable with what they offer. The price difference would be worth the overall upgrade the OnePlus 9 provides.
