Samsung Galaxy S21 Ultra Features And Performance

Samsung Galaxy S21 Ultra Features And Performance

The Samsung Galaxy S21 Ultra was released on January 14, 2021. It was made available for purchase on a number of carriers and was one of the top-selling devices in its class.

The Samsung Galaxy S21 Ultra has seen a lot of positive and negative reviews in its short life, but it is still available today.

The smartphone is part of the Galaxy S family and came out just a few days after the release of the S21 FE and was built to compete with other manufacturers’ flagship devices.

The Galaxy S21 Ultra is also available unlocked and it’s certainly worth looking into for a lot of reasons. The overall budget device does a lot to set itself apart from the crowd, but one of the things that makes this phone stand out from the pack is its battery. Here are the smartphone’s key features:

Samsung Galaxy S21 Ultra Network:

The Samsung Galaxy S21 Ultra is a 5G phone. It supports both LTE and 5G networks, which means it can be used on T-Mobile, Verizon, Sprint and other networks that are being rolled out.

5G networks are already becoming more common across the United States and other countries as well. The 5G network is a huge leap in technology and the Galaxy S21 Ultra is among the first phones to support it.

As soon as the phone is released in more countries, the network will continue to expand, so you’ll have plenty of opportunities to get your hands on a 5G device.

It’s more likely that the Galaxy S21 Ultra will be available for purchase in your country than an unlocked variant of the phone.

If you’re looking for an OpenSignal 5G phone, it’s a great choice since it’s already on the market and offers better roaming capabilities than other models.

Samsung Galaxy S21 Ultra Display:

Screen Size:

The screen size of the Samsung Galaxy S21 Ultra is a 6.8 inch edge Quad HD+ Dynamic AMOLED 2X Infinity-O Display. It has a 3200×1440 resolution, giving it a pixel density of 515 ppi.

This is without considering the fact that the phone also has an AMOLED display. The display has a 20:9 aspect ratio, so the screen is still wide enough to watch movies and TV shows on.

The smartphone has a screen-to-body ratio of 89.8%, which means that the screen is big enough to enjoy content but the phone itself is small enough to fit comfortably in a pocket.

The higher resolution allows you to see more image detail than with a 720p display. It also means that videos will look sharper and more detailed as well.

Overall, the display on this phone is fantastic, but it’s not perfect. The Galaxy S21 Ultra is still one of the best phones around in terms of display quality with a refresh rate of 120Hz.

The AMOLED technology allows it to have great contrast and it also offers a wide color gamut. This result in a more colorful, vibrant image that is sure to impress.

The phone can also be turned up to maximum brightness, which makes it easier to see outside. The brighter screen is useful even if you’re indoors because it can make it easier to read the text on your screen.

The screen size is pretty standard for smartphones. It’s large enough to watch videos and movies, while it’s small enough that you can still hold the phone in your hand.

The screen also has a notch at the top, which many people dislike but it doesn’t affect the display quality or use of the phone in any way. Still, it’s an odd design choice for Samsung to make and one that may not be popular with users.


The Samsung Galaxy S21 Ultra does have a near bezel-less display. This means that the phone has very minimal bezels around the screen, giving it a more immersive and sleek look.

This is a feature that is becoming more and more popular in smartphones, as it gives the device a more modern appearance. The bezel-less design relies on the use of a screen that is curved and wrap-around.

This can make it difficult to use the phone with one hand, which can become frustrating if you find yourself in an awkward situation, such as when you need to quickly look or reach for your phone while talking to someone.

However, there are certain benefits that come from using a bezel less display. Many people will prefer a phone with this feature because it looks more modern and sleek, but these benefits come at a cost.

Samsung Galaxy S21 Ultra Water, Drop And Dust Resistance:

Water Resistance:

The Samsung Galaxy S21 Ultra is water-resistant. You can submerge it in up to 1.5 meters of water for a period of 30 minutes and it will still work.

The phone is also protected from dust, which means you won’t have to worry about getting sand or dirt into the device.

The phone will be completely protected as long as you aren’t using it while swimming, snorkeling or scuba diving. It’s worth noting that the warranty doesn’t cover accidental damage and this includes damage caused by water damage.

The Samsung Galaxy S21 Ultra is a bit more durable than most other smartphones. The IP68 rating means that it can survive in the water and that it’s completely resistant, two things that aren’t offered with most other devices.

Even if you’re not planning on using this phone in the rain or underwater, this feature still provides peace of mind when using the phone.

Drop Resistance:

The Samsung Galaxy S21 Ultra is made of durable materials that can resist wear and tear. It is designed with Corning Gorilla Glass Victus in the front and back which improves its drop and scratch resistance, however, it is not completely drop resistant.

If you drop your phone, it is likely to sustain some damage. The good news is that Samsung offers a warranty that covers accidental damage, so you can get your phone fixed if it sustains any damage from a drop.

You should still try to keep your phone out of dangerous situations, but accidents do happen. The IP68 rating makes it a little less risky.

You know that if the device does fall into the water or is dropped, it will be fine. It’s not protected against extreme conditions like dunking or being crushed, but it can be used in all other situations.

The Galaxy S21 Ultra has a smooth finish on the back of the phone. If you use it with your case, it should stay protected and scratch free even after a few drops.

This is similar to what’s available with phones that are made by Apple as well. If you’re looking for something that can withstand drops and still be easy to hold and use, this may be one of the best choices.

Dust Resistance:

The Samsung Galaxy S21 Ultra is dust resistant. This means that it can resist the penetration of dust particles into its internal components.

The smartphone has an IP68 rating, meaning it is dust resistant. This is an important feature for a mobile device, as dust can cause damage to the sensitive electronic components inside.

The Galaxy S21 Ultra is also water resistant, meaning it can resist the ingress of water into its internal components.

This is another important feature for a mobile device, as water can cause damage to the sensitive electronic components inside.

The external shell of the phone is made of polycarbonate, which is a durable material. It’s not completely dust and water-resistant and so you should be careful when handling it with your hands.

The exterior gives you some protection against small particles, but it’s not completely protected against damage caused by large particles such as sand or dirt.

The anti-dust and anti-water damage features are nice to have on a smartphone because they can make them more resistant to small particles, such as dust and water.

However, even with all of these protective features, a device can only withstand so much damage before it breaks. The IP68 rating does help reduce the damage caused by small particles such as sand and dirt.

When handling your phone, you should use the supplied case to protect it from damage. The case will ensure that your phone is protected in all situations, especially too much dust.

Samsung Galaxy S21 Ultra Dimensions and Weight:

The dimensions of the Samsung Galaxy s21 Ultra are 165.1 x 75.6 x 8.9mm. The weight of this phone is 188 grams and the mmWave model weighs 229g, which makes it light and easy to carry around in your pocket or bag. It’s a sleek, slim design that looks good and feels comfortable in your hand.

The size of this smartphone is small but the screen is large, so you’ll still be able to see everything clearly on it despite its compact size and lightweight design. It’s easy to operate with one hand and you’ll be able to reach all parts of the phone with your thumb.

This will make your phone’s features easier to access and will open up more possibilities for your device. An example of an app that makes use of NFC is Google Pay. One of the most common uses is to make payments wirelessly through your smartphone.

Many stores will have a payment terminal that you can tap your phone against, which will allow you to pay for your purchase. You can also use it to download digital content, such as apps or digital tickets.

Samsung Galaxy S21 Ultra Memory:

Random Access Memory:

The RAM size of the Samsung Galaxy S21 Ultra is in versions of 12GB and 16GB.  Random Access Memory is a memory that tells your phone’s operating system where to store data when it needs to access it.

Modern smartphones have a lot of RAM, as they are designed to do many different things at once. They are used for more than just storing information and it’s possible for them to operate at the same time.

A smartphone with a lot of RAM can open multiple websites or photos at the same time. It can also run a lot of apps at the same time, or you can switch back and forth between them.

If your phone has a lot of RAM, it will be more responsive and you’ll be able to run more apps at the same time.

Read-Only Memory And Eternal Storage:

The internal memory of the Samsung Galaxy S21 Ultra is in versions of 128GB, 256GB, and 512GB. Internal Memory manages how much data can be stored on your phone’s built-in memory.

It also acts as a cache for data that you will be accessing more frequently. This means that you won’t have to download all of your photos, videos or music again and again.

Content that you regularly access will be stored on your phone’s internal memory, while data that you access less frequently will only need to be downloaded once.

This is beneficial if you don’t have a lot of storage space on your device. The more internal memory that is available on your phone, the more data can be stored.

The memory of this smartphone however is not expandable as it has no slot for microSD. This means that it may not be possible to add more memory to it, even though you would like to.

This will limit the usable storage space on this device and make it harder for you to put media onto your phone as well as use it for music, games or videos.
