| Weight | 184.5 g | 172 g | Zenfone 10 is noticeably lighter, reducing hand fatigue during extended use. |
| Foldable | Yes | No | Razr 40 Ultra offers a larger screen in a smaller form factor when folded, while Zenfone 10 provides a traditional smartphone experience. |
| Display | |||
| Size | 6.9" | 5.92" | Razr 40 Ultra boasts a much larger main display, enhancing media consumption and multitasking. Zenfone 10 is more pocketable and offers better one-handed usability. |
| Resolution | 1080 x 2640 | 1080 x 2400 | Both offer sharp displays, but the Zenfone 10 has a slightly higher pixel density (445 vs 413 PPI), resulting in marginally crisper text and images. |
| Refresh Rate | 165Hz | 144Hz | Both offer incredibly smooth scrolling and animations. The difference between 165Hz and 144Hz is negligible in real-world usage. |
| Type | Foldable LTPO AMOLED | Super AMOLED | Razr's foldable display allows for flexible usage scenarios, while Zenfone's traditional AMOLED provides durability and potentially better color accuracy. Data is insufficient to compare color quality directly. |
| Performance | |||
| Chipset | Snapdragon 8+ Gen 1 | Snapdragon 8 Gen 2 | Zenfone 10 features a newer and more powerful chipset, resulting in faster performance, improved efficiency, and better thermal management. |
| CPU | Octa-core (1x3.19 GHz Cortex-X2 & 3x2.75 GHz Cortex-A710 & 4x1.80 GHz Cortex-A510) | Octa-core (1x3.2 GHz Cortex-X3 & 2x2.8 GHz Cortex-A715 & 2x2.8 GHz Cortex-A710 & 3x2.0 GHz Cortex-A510) | Zenfone 10's newer CPU architecture provides a performance advantage, especially in demanding tasks and gaming. |
| GPU | Adreno 730 | Adreno 740 | Zenfone 10's superior GPU delivers significantly better graphics performance for gaming and visually intensive applications. |
| RAM | 8GB/12GB | 8GB/16GB | Both offer ample RAM for most users; however, the 16GB option on the Zenfone 10 provides better future-proofing and smoother multitasking for power users. |
| Camera | |||
| Main Camera | 12MP, f/1.5 | 50MP, f/1.9, Sony IMX766 | Zenfone 10's higher resolution sensor with a known model (Sony IMX766), larger sensor size (1/1.56"), and pixel binning technology likely results in better image quality, particularly in low-light conditions. |
| Video | Up to 4K@60fps | Up to 8K@24fps | Zenfone 10 supports higher resolution video recording. While 8K recording might not be widely used yet, it offers greater flexibility for future editing and viewing on higher-resolution displays. |
| Battery | |||
| Capacity | 3800 mAh | 4300 mAh | Zenfone 10 has a significantly larger battery, potentially leading to longer battery life. However, real-world battery life depends on various factors including usage patterns and software optimization. |

4. Decision Framework
Key Questions for Buyers:
- Form Factor Priority: Is a foldable design with a large cover screen essential, or is a traditional smartphone preferred?
- Performance Needs: Are demanding tasks like gaming and heavy multitasking a priority, or are basic smartphone functions sufficient?
- Budget & Value: Considering the price difference (if any) and features offered, which phone provides the best value for your specific needs?
Scenario-based Recommendations:
- Heavy Gamer: Asus Zenfone 10 for its superior performance.
- Social Media Enthusiast: Razr 40 Ultra for its large screen and portability, assuming battery life is sufficient for their usage.
- Photographer: Zenfone 10 for its better camera.
My Choice: Asus Zenfone 10
While the Razr 40 Ultra's foldable design is intriguing, the Zenfone 10's superior performance, camera, and battery life are more important to me. I prioritize a smooth and powerful user experience, especially for gaming and multitasking. The compact size of the Zenfone 10 is also appealing, as I prefer phones that can be easily used with one hand. The newer Snapdragon 8 Gen 2 chip, coupled with the Adreno 740 GPU, ensures smooth performance for years to come. The improved camera system, particularly the larger sensor on the main camera, is also a significant factor in my decision. Although the foldable form factor is innovative, the trade-offs in performance and battery life are too significant for my personal needs.
