Samsung Galaxy S21 vs Galaxy S21 Plus vs Galaxy S21 Ultra

Okay, so we know that Samsung is a major player in the world of mobile phones. Premium materials, crisp & expansive screens and Android operating systems makes Samsung a popular choice for sleek and capable smartphones.

The most recent versions of the Galaxy model are incredibly powerful. The release of the Galaxy S22 in February 2022 means that if you’re looking for quality refurb you can generally get a great deal on the Galaxy S22’s predecessor; the Galaxy S21.

There are 3 models to consider when it comes to the Galaxy S21 family. So aside from price, what are the main differences between the Samsung Galaxy S21, the Samsung Galaxy S21 Plus and the Samsung Galaxy S21 Ultra

Samsung Galaxy S21 Ultra Plus

The Samsung Galaxy S21

This phone is essentially the stripped down and practical model of the bunch. With it’s slightly smaller size, it's easy to handle with a friendly price point. Even though this model has a polycarbonate casing (rather than Gorilla Glass Victus) you can always pop a case on it for added protection if you’re worried. 

The Samsung Galaxy S21 Plus

This is the midrange model of the S21 family. The Plus is made to be more durable than the standard S21 with a glass back and larger display for enhanced viewing. The Plus should hold a longer charge than the Galaxy S21 but not quite as much as the Ultra. The FHD screen is the same resolution as the S21 as well. It’s a slight upgrade from the standard S21 but the main differences are their glass casing and size. 

The Samsung Galaxy S21 Ultra

This is the premium phone of the lot. With the largest screen and QHD resolution for a more detailed viewing experience. The camera on the Ultra has an improved Bright Light sensor. That means that you’ll be able to take better evening and low-light photos. This smartphone also has the biggest battery of the bunch.
