If you prioritize a stellar camera system, the Samsung Galaxy S21+ has a slight edge, especially for video recording. However, if battery life is more critical for you, the OnePlus 12R offers more extended battery life. Both phones have similar screen sizes, but the OnePlus 12R has a slightly larger and higher-resolution display, which might be more appealing if you consume a lot of media on your phone. Keep in mind that the OnePlus is more expensive, and if cost is a major factor, the Galaxy S21+ provides considerable features at a typically lower price point. Both phones run Android, so the operating system shouldn't be a deciding factor. 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."
