If you prioritize a better camera system including the ability to shoot high-quality video, you will appreciate the Samsung Galaxy S21 Ultra as it features more advanced photography capabilities. However, the Samsung Galaxy A53 is a more recent model with a very good camera system of its own, and it offers a more budget-friendly price point. The S21 Ultra also boasts a larger, curved screen which is brighter and has a higher resolution compared to the A53's screen. On the other hand, the A53 has a longer battery life. Both phones have 5G connectivity and run on the Android operating system. The S21 Ultra has additional premium features like glass back, higher RAM, and a more powerful processor, whereas the A53 offers a plastic back and sufficient performance for everyday tasks.

Android Authority

Ryan Haines | May 2023
"Samsung’s quartet of rear cameras delivers the goods, both day and night, with the only blemish being the lack of 4K/60fps video recording. The large, 6.5-inch, 120Hz AMOLED display is crisp and smooth, making video streaming enjoyable. You should have no issues pushing the 5,000mAh battery to its limits and it’s not too slow to charge relative to its competitors in the US."
