- Compact Form Factor: I prefer a smaller, lighter phone, and the Zenfone 9's compact size makes it more convenient for one-handed use and carrying around.
- Advanced Features: The fingerprint sensor, better connectivity (Wi-Fi 6, Bluetooth 5.2, advanced GPS), and build quality provide a much more polished and modern user experience.
While the Galaxy A02s has a larger battery, the Zenfone 9's faster charging can mitigate the impact of the smaller battery capacity. Ultimately, the Zenfone 9's superior performance, display, camera, and overall user experience outweigh the potential advantage of a slightly larger battery in the A02s, making it the better choice for me.
