The Samsung Galaxy A54 has a decent camera and a good battery life housed in a glass body, but the Samsung Galaxy S21 Ultra offers a significantly superior camera setup with a telephoto lens that can achieve 10x optical zoom, along with a larger, higher-resolution screen that supports HDR10+, making it better for media consumption. Although the A54 is newer, the S21 Ultra, despite being an older model, includes advanced features like S Pen support and a higher-quality display. If camera and display quality are your priority and you're okay with an older model, the S21 Ultra may be the better choice despite being slightly less expensive than the A54. Give Feedback

The Verge
Allison Johnson | April 2023
"As far as midrange phones go, the A54 has all the right stuff: a big 6.4-inch screen, very good battery life, a durable build to withstand water and dust, and a support policy promising security updates for five years. If you squint at that spec list, you can almost see a thousand-dollar flagship phone. Almost."
