The Samsung Galaxy S24+ has a higher-resolution screen and a more powerful processor, which can deliver better performance and sharper visuals, but these upgrades do come at a higher cost. The camera of the S24+ also sports more megapixels and offers better photography and videography capabilities, including improved low-light performance. If battery life is a concern, the S24+ slightly edges out the S21+; however, both should last a full day on a single charge. If budget is a main factor and you're satisfied with solid performance and a good camera, the S21+ is more wallet-friendly. Keep in mind the S24+ has additional longevity due to being a newer model, which might make the upfront cost more justifiable for long-term usage. Both models have a 6.7-inch screen, but the S24+ screen is curved and has a higher refresh rate variability, leading to potentially smoother visuals. Give Feedback

"All told, Samsung nailed it with the Galaxy S21 Plus. It has most of the strengths of the smaller S21 in a bigger package. It’s got a lot going for it. If you’re coming from an older device, like the Galaxy S10 series, this is a solid upgrade."
