If I had to choose between these two phones, I would pick the Samsung Galaxy S21 Ultra 5G. While it is an older phone, it offers a significantly better display, far superior performance, a more versatile and powerful camera system, and wireless charging capabilities. These advantages greatly outweigh the lighter weight and slightly faster charging of the Motorola G85 for my specific use case.

While the G85 is a good option for a budget conscious buyer, the S21 Ultra is still a much better phone overall.
