My Choice
If I were choosing between these two phones, I would choose the Asus Zenfone 8.
Here’s why:
- Performance is a Priority: The Snapdragon 888 chipset is a major advantage. As someone who often multitasks, edits photos, and sometimes plays games, the Zenfone 8's processing power will offer a smoother and faster experience. The Antutu score difference is vast, suggesting a significant real-world performance difference.
- Superior Display Quality: While I appreciate a large display for media, the quality of the AMOLED panel, along with the higher refresh rate (120hz vs 90hz) and the sharpness makes it significantly better than the Redmi 13's LCD panel, offering a more enjoyable visual experience.
- Camera Versatility: The Zenfone 8’s camera features (8K video, OIS, RAW capture, wide-angle/macro lens) provide significantly more flexibility and creative options. While the Redmi 13 has a 108MP main sensor, the Zenfone 8’s feature set and additional lenses is more important for me personally. DxoMark scores also show its significantly better camera performance.
- Compact Form Factor: I prefer the smaller, more pocketable size of the Zenfone 8, it makes it more comfortable for one handed use.
- High-Quality Audio: The inclusion of Hi-Res Audio and stereo speakers is a definite plus for my media consumption needs.
- Durable screen: The Gorilla Glass Victus is superior to the Redmi 13's unknown screen protection.
While the Redmi 13 has a larger battery and is likely more affordable, the Zenfone 8 provides a noticeably superior experience in the areas I prioritize: Performance, Display, and Camera. Although it's an older phone, it is still a very competitive device if purchased at a reasonable price.
