Hey there, the world’s most specc’d-out camera phone, Galaxy S21 Ultra! When Samsung announced your predecessor with a 108MP camera sensor, 5x periscope zoom and 5000mAh battery, we thought this can’t be beat!
Fast forward less than a year, and the Galaxy S21 Ultra still carries the same humongous battery, but has done the near-impossible, taking the record-beating camera kit further to earn the world’s best camera phone specs title. 
If two optical zoom systems and a 108MP sensor that can focus this time around aren’t enough for you, Samsung throws in the kitchen sink in terms of display and connectivity technologies, too, so let’s preview how the king of Samsung’s S21 series block looks and behaves.

Samsung Galaxy S21 Ultra colors, display, and S Pen cases

  • Phantom Black and Silver will be followed by Brown, Navy Blue, and Titanium S21 Ultra colors
  • 6.8″ Dynamic AMOLED 2x display with 10Hz-120Hz @ 1440p adaptive refresh rate

We’ll save you the suspense, the S21 Ultra is huge. Albeit a tad smaller than the S20 Ultra before it still clocks in way above the comfortable to hold and use with one hand mark, both in dimensions, and in weight. Luckily, Samsung’s new Contour Cut Camera design that fuses the camera island with the steel frame adds to the aesthetics of the device enough so that it doesn’t look as big and blocky as it could have.

To make the ergonomics story more complicated, however, Samsung equipped the S21 Ultra with an S Pen digitizer for the first time outside of the Note family, and make the stylus available for the phone with select cases, like the Clear View or Silicone Covers. Tack on one of these in order to utilize the S Pen, and not only the base $1199 price becomes even higher, but the width even larger, to the point of no choice but to use the phone with two hands.

On a positive note, Samsung has shaved off the bottom bezel, and shrunk the 6.8″ display panel slightly from its predecessor just enough to make it feel the same with an S Pen case on, which is to say gargantuan. Thankfully, the so-called Dynamic AMOLED 2x display is still curved on the sides, so it’s fairly possible to hold it and control at least the mid-section of the screen with one hand. 

Moving on to the most important part of today’s phones, the screen, Samsung told us that the “Galaxy S21 Ultra pulls out all the stops for those who want Samsung’s best of the best.” How so? Well:

Equipped with powerful AI and our most advanced pro-grade camera system and brightest screen — featuring an adaptive display that supports a refresh rate from 10Hz to 120Hz at Quad HD+ quality — Galaxy S21 Ultra raises the bar of what premium smartphones can do.

Pay attention to that “brightest” part and the 10Hz-120Hz specs at the full 1440p resolution. Yes, that means that the S21 Ultra is equipped with the newest LTPO OLED display technology that allowed for both the record 1500nits of peak brightness, and the battery-saving, dynamically-allocated refresh rate that can go down to 10Hz when you are looking at static images, or rev up all the way to 120Hz when you scroll. This granularly adaptive refresh rate is what makes the S21 Ultra display, in particular, stand out. 

Last year, Samsung dropped the ball in comparison with the competition from OnePlus or Oppo with static high refresh rate that worked only in 1080p mode, and was constantly on 120Hz at that, taking a huge toll on the S20 Ultra battery life, but now its heir fixes all wrongs making the S21 Ultra display the one to beat later in the year.

Samsung Galaxy S21 Ultra camera pictures and video recording

The best phone camera $1299 can buy
  • S21 Ultra camera specs: 108MP main/10MP 10x zoom/10MP 3x zoom/12MP ultra-wide/40MP selfie cameras.
  • New S21 Ultra photography features: 12-bit HDR RAW photos, Bright Night mode, Portrait mode with improved separation for selfies, Zoom Lock for clear shots at up to 100x.
  • New S21 Ultra video features: Super Steady video at 60fps, 8K Snap, Director’s View, and Single Take with Dynamic Slow-mo.
Remember Apple’s boast that the iPhone 12 series can both capture and play Dolby Vision HDR? Well, it’s still 10-bit one, while the S21 Ultra not only introduces a double-zoom camera set, but has upgraded its imaging processor to allow for 12-bit capture, for “64x richer color data and 3x wider dynamic range.” Bazinga!
Moreover, the phone carries Samsung’s third-gen 108MP sensor with improved autofocus that should hopefully do away with the focusing issues that plagued the second-gen one in the S20 Ultra. Both the 10MP 10x periscope zoom, and the 10MP 3x telephoto zoom sensors sport Dual Pixel autofocus, for the ultimate in camera focusing abilities, as we all know how shaky and blurry things can get when zoomed in. For the purpose of clarity, Samsung also introduces Zoom Lock, an stabilization tech for precisely those enlarged shots, too.

Why would you need two zoom cameras, though? Well, depending on which object you tap and choose, the AI module automatically chooses which zoom camera to use, as mid-range and long-distance zoom abilities have very distinct scenarios and require different technologies to turn out right.

Thanks to the Snapdragon 888 or Exynos 2100 chipsets’ image processing abilities, the Bright Night 108MP sensor now captures 12MP nona-binned shots that would be second to none as the sensor can snap multiple photos with different exposure much faster than before, for a much brighter Night Mode with cleaner, more defined, well-exposed low-light shots.

Samsung Galaxy S21 Ultra software and Snapdragon vs Exynos processor performance

The best mobile chipsets out there finally get 5G integration

Ladden with the latest One UI 3 edition of Samsung over Android 11, the Galaxy S21 Ultra adds several of Samsung’s tried and true stylus-specific apps and fucntions to justify the presence of a digitizer. The S Pen has to be acquired separately with a dedicated case but it does all the hovering, clicking, anotating and doodling in Samsung’s Notes app one would expect from it.

The fact that the phone come with at least 12GB RAM in its 128GB/256GB configurations, and a whopping 16GB/512GB model means that it can chew through any task you throw at it, no matter whether you have the Snapdragon 888 or Exynos 2100 version. 

Both are made on Samsung’s frugal 5nm EUV process and return record high benchmarks in the Android world, plus they have integrated 5G modems for added power draw optimization. The Exynos is clocked higher than the Snapdragon in benchmarks, so it returns higher scores, but we will see about the sustainged performance over time.

Samsung Galaxy S21 Ultra battery life and charging speeds

Big battery, big responsibilities
  • 5000mAh battery good for a full intensive day off the charger, according to Samsung
  • 25W Super Fast Charging (wired)
  • 15W Wireless Charging
At first blush, the top-shelf member of the S21 series should beat them all, as it has the biggest battery and the same key power draw advantages as the other two – a 5nm Snapdragon 888 or Exynos 2100 processors with integrated 5nm 5G modems and new, more frugal antenna materials.

The key element for greater Galaxy S21 series battery life when compared to the S20 models – FHD instead of QHD display resolution – however, is missing from the equation on the Ultra. Given that the S21 Ultra is flaunting the same 5000mAh battery piece as the S20 Ultra, and the same high display pixel density, the only battery life gains compared to its predecessor should come from the 5nm chipset and 5G antennas, right?

Well, not really, as this time around, its QHD display will be of the more frugal LPTO variety, not the LTPS panel with static 120Hz refresh found in the S20 Ultra. That alone would amount to a 15-20% diminished power draw. When we add the dynamic refresh rate that LTPO allows which only uses 120Hz when it matters – i.e. when browsing and scrolling, or during interface animations – the battery savings may be as significant as having a lower-res display.

That is why the S21 Ultra battery life round will be fought and won during our battery benchmark tests. All in all, battery life of the two top members of the Galaxy S21 line should be a sight to behold given all the upgrades in component power draw, and we can’t wait to put them to a real life battery test.
