If you prioritize a compact phone with a headphone jack, the Asus Zenfone 9 would suit you well, and it has a slightly larger battery than the Samsung Galaxy S23. However, if a more recent phone with a slightly larger screen is preferred, the Samsung Galaxy S23 could be a better fit; it also offers wireless charging which the Asus does not. Both have high-quality OLED displays with similar resolutions, but the Samsung's screen is a bit brighter. Camera-wise, the Samsung Galaxy S23 offers a slightly more versatile setup with a higher resolution zoom camera. Both run Android and provide a similar base storage, so your choice may also hinge on brand preference or specific features like Samsung's Wireless DeX. Give Feedback

Android Authority
Robert Triggs | March 2023
"The Asus Zenfone 9 is a compact device that still packs more than enough power under the hood. It's compact size, Bluetooth and audio features (including a headphone jack!), and hardware gestures combine to offer a package that does enough differently to warrant your attention."

The Verge
Allison Johnson | February 2023
"The 6.1-inch S23 is the best reasonably sized Android phone on the market in the US, partly because almost every other Android phone sold here is gigantic. But it’s also a really good device, with a battery that gets through a full day more comfortably than its predecessor. The Snapdragon 8 Gen 2 chipset responsible for some of that battery performance improvement is slightly different — and slightly faster — than the 8 Gen 2 in other Android flagships."
