My Choice
I would choose the OnePlus 9RT 5G. While the Xiaomi Redmi Note 9T offers a larger battery, the OnePlus 9RT 5G’s advantages in key areas like processing power, display quality, camera performance and overall user experience make it a much more compelling device. The significantly faster charging of the OnePlus also mitigates the smaller battery capacity. The difference in performance between the chipsets is substantial, meaning day-to-day use is a better experience with less lag or slow down. The AMOLED screen on the OnePlus with a 120Hz refresh rate is a major upgrade for media consumption and general usage, and the enhanced audio quality is a nice touch. While the Redmi Note 9T does have better screen protection and an ultrasonic proximity sensor, those are not enough to offset the major advantages of the OnePlus 9RT 5G. For me, the higher price is justified by the superior experience it offers.
