- Scenario 2 (Performance & Multimedia): If you need a high-performing phone for gaming, photography, video editing and multimedia consumption, the OnePlus 9 Pro is the better choice.
- Scenario 3 (Balanced): If you want a good all-round experience with long battery life and a newer operating system, you may consider a different phone altogether, as neither the OnePlus nor the ZTE provides this balance.
My Choice
If I were choosing between these two phones, I would pick the OnePlus 9 Pro. The sheer difference in performance, display quality, and camera capabilities makes it the superior device for my needs. While the ZTE offers a larger battery, a newer operating system out of the box, and is likely more affordable, the performance compromise is too great. I value smooth multitasking, a high-quality display for media consumption, and a capable camera for both photos and videos. The faster charging and wireless charging capabilities of the OnePlus are also very valuable to me. While the battery life may be slightly shorter, I find fast charging more convenient for my lifestyle, plus I can use reverse wireless charging when needed.
