Samsung Galaxy S21 Ultra | Design Review

The Samsung Galaxy S21 Ultra is the epitome of smartphone technology. Yes, it may be a monolith in size, but its sleek design and cutting-edge features make up for this inconvenience tenfold. 

The S21 Ultra is a sleek and slim device that does not feel bulky. It has curved edges, unlike the flat screen of my old Galaxy phone, but it isn’t bothersome or annoying to use at all.

The Samsung Galaxy S21 Ultra is the perfect phone for those who require their handiwork to be a little more in-your-face. The sturdy, unapologetic style of this device will always stand out from the hordes of other devices on display as it screams, “look at me.”

Samsung Galaxy S21 Ultra | Display Review

The Samsung Galaxy S21 Ultra display comes in just two colors from carriers: Phantom Black or Phantom Silver; I’m leaning toward black because it’s slimmer than silver color options. 

Samsung offers exclusive S21 Ultra colors on their website, including navy blue (which looks stunning), phantom titanium gray, and brown. Best Buy has an entire Navy B, which you can only purchase there.

The new Galaxy 21Ultra measures 0.35 inches thin with 8 ounces weight making it thinner and lighter than other smartphones like the iPhone 12 Pro Max while still being st.

The S21 Ultra is a beautiful phone with an eye-catching screen. That produces 81.4% of the demanding DCI-P3 color gamut – more than 84.8% for the iPhone 12 Pro Max. The colors were also rendered very accurately on this Samsung Galaxy model. With a Delta E score of 0.07 compared to Apple’s (0.35). 

This device does not disappoint when it comes to contrast ratio. At 50%, it’s higher than what you can get from any other smartwatch out there right now. And just one example among many in which Samsung improved over its predecessor by leaps and bounds.

If you’re a fan of big displays, the Samsung Galaxy S21 Ultra will not disappoint. The 6.8-inch display is perfect for anyone looking to use their phone outdoors. Or who wants an immersive experience watching movies and playing games on it without having to squint at your device. 

This future smartphone also has an ample bezel that feels like less work when scrolling through webpages, emails, etc. So this may be something many people look forward to.

Samsung Galaxy S21 Ultra | Camera Review

The Galaxy S21 is a smartphone that stands out in the market for its cameras. The primary sensor has 108MPs, and it’s accompanied by an ultra-wide camera with 12MPs resolution to capture as much of your surroundings as possible. 

But what sets this phone apart is two things: It comes equipped with laser autofocus technology. So you never have any difficulty finding your subject again. There’s also something called “Super Night Scene,” which uses AI to make dark scenes brighter without sacrificing quality.

Zoom-In Features

The Galaxy S21 Ultra will make you feel like a secret agent as they zoom in. At the same time, the iPhone 12 Pro Max is stuck at 2.5x optical zoom. The S21 Ultra packs two telephoto lenses of 3x and 10x optical zoom to capture 108MP photos with 64 times richer color data.

The latest Dual zoom lens system on the Galaxy S21 Ultra is faster and sharper than before. The Dual telephoto lens of this phone performs a 3x to 10x switch with hyper-detailed 100X zooming.

All without breaking focus in between each change. Zoom lock supports are also included for helping maintain control when using high magnification zooms.

More than three time’s dynamic range compared to its predecessor – not to mention an unprecedented RAW file option for editing pros in pro mode.

Snaping Features

The Galaxy S21 Series is redefining the meaning of natural selfies as a result of AI Restoration and Studio-level Lighting. This results in clearer details, blemishes being removed, while maintaining skin tone and texture.

The low light shots with these smartphones are now even more enhanced by automatically multi-frame processing that lights up night scenes to capture them vividly in beautiful color detail!

Recording (Video) Features

The Galaxy S21 Ultra can record 8K video up to 30 fps on the video front, and all of its cameras can capture 4K at 60fps. But the most remarkable feature is Director’s View which lets you use both your selfie cam and back-facing camera simultaneously for recording vlogs. 

The system also has live thumbnails so that you know what angle each camera captures while filming – perfect if deciding whether or not it’s time to call someone in a Skype chat.

Samsung Galaxy S21 Ultra | Battery Review

If you’re looking for a phone that can last all day, this is it. On our web surfing battery test over 5G, the S21 Ultra endured 11 hours and 25 minutes which beats both iPhone 12 Pro Max (10:53) and lands on our best phone battery life list. 

In standard 60Hz display mode turned on, we see less of a difference, but if using the adaptive method with up to 120 Hz engaged, then period decreased by 40% from 10 hrs 7 mins in standard modes down to 6 hr 29 min with an adaptive set as default.

The new Samsung Galaxy 21R has become many people’s favorite phone because they don’t need an external charger every night like before with other smartphones – no matter what screen brightness.

When looking for a phone charger, it is essential to consider the outlet you are using. If you do not have USB-C and haven’t purchased your last few phones in the past couple of years, this will mean more money coming out of pocket if you want to be green. 

The S21 Ultra reached 56% at 30 minutes with a 25-watt charging speed. Still, only 31% after 15 minutes on a standard wall socket set up that was used before mobile chargers were popularized and adopted as a mainstream technology.

Samsung Galaxy S21 Ultra | Advanced Features Review

S Pen

For the first time, a Galaxy S device supports the S Pen. The new Samsung Galaxy S21 Ultra is so innovative that it features an in-display Wacom digitizer to make this possible.

Designers and artists will love how you can draw or sketch with precision accuracy using your favorite stylus on its large screen display. This also comes in handy for signing documents quickly without taking out the pen from your pocket as well, which makes life much easier when many things are going around all at once.

Wireless Standards

The Samsung Galaxy S21 Ultra is the first device to support all of the latest wireless standards. The Qualcomm X60 modem inside this phone will allow users to get higher peak speeds while delivering better power efficiency.

So they can talk and text longer without having a battery that runs out too quickly or constantly charges their phones overnight.

The Galaxy S21 Ultra has all the features you’ll need to take advantage of today’s wireless networks. It is one of the first phones on the market that supports Wi-Fi 6E, which delivers faster speeds and more overall bandwidth when combined with a compatible router or device like your computer. 

In addition, UWB (ultra-wideband) makes it easier than ever before for users to share files in seconds by simply touching devices together – perfect if you’re trying to send images from your phone quickly!

Samsung Galaxy S21 Ultra | Software Review

The Samsung Galaxy S21 Ultra runs the latest Android 11 and One UI 3.1 from Samsung, bringing new features like bubble notifications for better organization on your phone; widgets can be accessed quickly with a swipe to the left (or right) edge any screen.

The volume control has never been more precise as you now have an individual level adjustment slider bar in addition to just basic up/down buttons – life-changing.

The update also includes background call videos. Users are not interrupted while multitasking or waiting for their turn at FaceTime video calls—bravely breaking all face-to-face contact barriers.

Samsung Galaxy S21 Ultra | Over All Performance Review

The Samsung Galaxy S21 Ultra is the first device in the United States to feature a new Qualcomm Snapdragon 888 mobile platform, and as expected, this phone flies. The global model of this device will launch with Samsung’s own Exynos 2100 chipset.

The Galaxy S21 features an exciting spec sheet featuring 6GB RAM and 128 GB storage space, along with many other high-end specifications that you would expect from any flagship smartphone released these days.

I am pretty impressed with the performance of this device, notably because it never slowed down or stuttered. It handled every task I threw at it without issue, and its lightning-fast processor made even my most demanding apps feel easy to use. 

What’s more is that on top of a powerful Snapdragon 888 chip, 16GBs worth of RAM is available for all your multitasking needs, making the whole experience truly seamless.

Frequently Asked Questions

Q: Is the Samsung Galaxy S21 ultra worth it?

A: The Galaxy S21 Ultra is one of the best phones money can buy. It offers a beautiful design and has all the features you could ever want in a phone, along with some completely new Android. However, it does have its drawbacks, such as no charger included in the box, but overall, this may be your next significant investment.

Q: Is the S21 Ultra the best phone?

A: Whoever said the iPhone was better than Samsung? The new Galaxy S21 Ultra 5G is a top-notch premium phone recognized for its innovative design and a wide variety of features. It’s worth looking at if you are in the market for an upgrade.

Q: What is the difference between Samsung S21 and S21 Ultra?

A: The Samsun Galaxy S21 doesn’t have a wider displaying screen than the S21 Ultra. Also, the camera quality and advanced software make the Samsung Galaxy S21 ultra first choice of people.

The Galaxy S21 is likely not too big for your hand (unless you have tiny hands), while the Ultra might be, and that’s not just down to its screen size. The S21 is thinner than the Ultra by 1mm on all sides, which may sound like a measly amount, but it can make a noticeable difference when holding one or the other in person.

Q: Which phone is better, S21 or S21+?

A: The S21 Ultra is better than the S1+ in a few key areas — it has more RAM, up to 512GB of storage, and differing camera setups. The 12MP primary lens on the previous model was replaced with a 108MP telephoto one that can take amazing close-up pictures while also providing some zoom degree. There are two lenses for both wide-angle shots and zooming at all angles, including those from afar.
