Final Thoughts
The Asus Zenfone 9 and Xiaomi Redmi Note 12 4G are two very different phones, catering to different users. The Zenfone 9 offers uncompromising performance, a top-tier camera, and a premium, compact design, but at a higher price point. The Redmi Note 12 4G offers a larger display, good battery life, and a low price, but compromises in performance and camera quality. The right choice depends on your specific needs, priorities, and budget.
My Choice and Explanation
Personally, I'd choose the Asus Zenfone 9. Here's why:
As someone who values performance, I often find myself pushing my devices to their limits. The Snapdragon 8+ Gen 1 chip, paired with the 16GB of RAM, would ensure buttery-smooth performance for everything from app development and video editing to gaming and heavy multitasking. The superior camera system and it's gimbal stabilization are also very compelling for someone who has a passion for photography. While the smaller screen and battery might be considered drawbacks, the improved video recording, camera quality, and compact form factor are significant advantages that outweigh the negatives for my personal use case. Also, the improved connectivity with Wi-Fi 6, Bluetooth 5.2, and more advanced GPS means that my daily connectivity needs are future proofed for a while.
For me, the Zenfone 9 is not just a phone, it's a mobile powerhouse and pocketable computer that I can use to do everything with no compromises, it is the best all rounder for my needs and that makes it the clear winner. While the Redmi Note 12 4G is a great budget device, it just doesn't provide the top tier experience and the performance needed for my daily use case.
