(Image credit: Future)

The Samsung Galaxy S21 Ultra is a monolith of a phone. Yes, the contour cut camera kiến thiết blends the camera bump into the glass back, but this is still a massive device you’ll want khổng lồ use with two hands.We"ve recognized as the best designed device in our Tom"s Guide Awards 2021 for phones.

With its 0.35 inch profile and weight of 8.08 ounces, the S21 Ultra is thicker và heavier than the iPhone 12 Pro Max. The display is gently curved, unlike the fully flat regular Galaxy S21, but not annoyingly so. I never accidentally tapped something on screen as I did with last year’s Ultra.

The Galaxy S21 Ultra comes in just two colors from carriers: Phantom Black và Phantom Silver. I might go with đen because of its slimming effect.Samsung.com is offering exclusive S21 Ultra colors, though, including Phantom Navy, Phantom Titanium & Phantom Brown.Best Buy has an exclusive Navy xanh colorway, also.

One of my favorite design upgrades is the 1.7x larger fingerprint sensor. It makes it easier to unlock the phone, and I found that the S21 Ultra didn’t ask me to press the sensor again like previous phones.

The 6.8-inch Dynamic AMOLED display on the Galaxy S21 Ultra is simply one of the best screens on a phone. It"s bright, vibrant and doesn"t make you choose between the highest resolution & highest refresh rate lượt thích its predecessor.

Yes, you’ll be mesmerized when watching videos on this phablet. The colors are as rich as ever, & the viewing angles nice và wide when bing watching on Netflix.

But the Ultra surpasses the iPhone with its dynamic refresh rate. Not only vì you get super smooth scrolling & gameplay, you now get 120Hz and quad HD resolution at the same time. So you don’t have to lớn choose between the highest resolution và highest refresh rates.

The S21 Ultra is also smart enough lớn automatically dial the refresh rate all the way down to lớn 10Hz to help save on power.

More good news, the S21 Ultra’s display is easy to read outdoors, because it can reach a peak rated brightness of 1,500 nits. In our testing, the S21 Ultra averaged 821 nits, which beats the iPhone 12 Pro Max’s 654 nits.

The Galaxy S21 Ultra will make you feel like a secret agent as you zoom in. While 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.

I was amazed how close I got khổng lồ this sign well across a highway. At 100x the zoom does get shaky but the new Zoom Lock feature can help you get a steadier shot with just a tap.

The 108MP main camera can capture 12-bit HDR photos with 64 times richer màu sắc data & more than three times the dynamic range of the S20 Ultra. Plus, there"s a 12-bit RAW file option in Pro mode.

I tested the camera out at a nearby store lớn capture a shot of produce, and the green peppers in the foreground look shiny and delicious. & you can make out a pretty amazing amount of detail when you zoom in.However, by comparison, the iPhone 12 Pro Max’s shot looks even more vibrant.

The Galaxy S21 Ultra is also a great partner to lớn have when you"re outdoors. Take this photo of towering trees I took at a nearby park. You can make out fine detail in the bark, & the phone does a great job capturing the clouds against the xanh sky even while dealing with all of the shadows in the foreground. I slightly prefer the S21 Ultra’s photo in this case to lớn the iPhone 12 Pro Max, but it’s really close.

Samsung says it has also improved the Portrait mode on the S21 by leveraging AI to lớn better separate the subject from the background. The S21 Ultra delivers a great bokeh effect here. My skin tone is warmer on the iPhone 12 pro Max, but overall the S21 shot looks great.

The Galaxy S21 Ultra also performs quite well in low light, thanks to lớn a faster Bright Night sensor and 12MP nona-binning technology for reducing noise reduction.In this comparison you can make out more of the stones & bushes in the foreground in the S21 Ultra’s photo compared khổng lồ the iPhone 12 Pro Max, although the iPhone’s colors look more natural.

If you want khổng lồ take photos và stills at once, the Single Take 2.0 feature on the S21 Ultra is pretty fun. It managed khổng lồ capture my attempt at a reverse layup in slow mo & pick a pretty good photo at the đứng đầu of the jump.However, the music Samsung chooses sometimes for its auto-generated đoạn phim clips sounds cheesy.

And this is one fast game android phone. The S21 Ultra didn’t flinch as I sliced through multiple enemies in Grimvalor while delivering console-quality visuals.

This flagship backs up my experience with impressive benchmark scores. On Geekbench 5, the S21 Ultra notched 3,440 on the multi-core test and 1,123 on single-core. That’s behind the iPhone 12 Pro Max, which cleared 4,100 và 1,600, but it’s still the best scores we’ve seen from an apk phone.

The S21 Ultra also fared well on the 3DMark Wild Life graphics benchmark, hitting 34 fps. The iPhone 12 Pro Max averaged 54 fps.

On our video clip editing demo using the Adobe Premiere Rush app, the Galaxy S21 Ultra took 1 minute and 2 seconds khổng lồ transcode a 4K clip to 1080p. That’s faster than the cảnh báo 20 Ultra’s 1:16 but still well behind the iPhone 12 Pro Max’s 28 seconds.

Unfortunately, while you have a range of storage options lớn choose from for the S21 Ultra — 128, 256 or 512GB — Samsung ditched the microSD thẻ slot. So you can"t expand.

(Image credit: Future)

If you’re looking for a phone that can last all day, this is it. On our web surfing battery chạy thử over 5G, the S21 Ultra’s 5,000 mAh endured for 11 hours & 25 minutes. That beats the iPhone 12 Pro Max’s 10:53 and lands the Ultra on our best phone battery life list.

Note that this time is with the standard 60Hz display mode turned on và that you’ll see less battery life with adaptive mode (up lớn 120Hz) engaged. In this mode we saw a runtime of 10 hours & 7 minutes.

The biggest bummer is that you don’t get a charger in the box. Yes, it’s the green thing lớn do, but if you haven’t bought a phone in the last couple of years và don’t have USB-C, it will mean more money coming out of your pocket.

Using a 25-watt charger, the S21 Ultra reached 56% in 30 minutes và 31% in 15 minutes.

Samsung Galaxy S21 Ultra review: S Pen


(Image credit: Future)

For the first time ever, a Galaxy S device supports the S Pen, the S21 Ultra makes that happen with a Wacom digitizer built into the display. The S Pen, which is optional, lets you draw, sketch & take notes, just as you can on the Galaxy cảnh báo 20 and lưu ý 20 Ultra. It also comes in handy for quickly signing documents.

Just keep in mind that the S Pen is sold separately, & you"ll need lớn spring for a compatible case if you want khổng lồ store the stylus on the go when it"s not in use. Samsung sells a Silicone Cover with S Pen included for $69.99.

I tried out this case, & it adds bulk khổng lồ already bulky phone. The S Pen functionality worked pretty well, và you can enjoy features lượt thích Screen Off memo for quickly jotting down notes. However, because công nghệ bluetooth không dây isn"t built in, you can"t use the pen as a remote control as you can with the chú ý 20 Ultra. So you can"t skip tracks with a button press or control slideshows.

Samsung is developing a second stylus. The S Pen Pro ships later this year for an undisclosed price, which will include bluetooth connectivity.

In addition, the Galaxy S21 Ultra is one of the first phones to tư vấn Wi-Fi 6E, a new standard that delivers faster speeds and more overall bandwidth when you have a compatible Wi-Fi 6E router.

(Image credit: Future)

Samsung has nearly perfected the big-screen phone with the Galaxy S21 Ultra. The display is best-in-class, the cameras are much improved & you can even use this thing as a Galaxy note if you want to.

Personally, I see the S Pen tư vấn as more of a bonus because of the added cost.

There are some things I don’t lượt thích about this flagship.

Then again, Samsung’s phone lasts longer on charge và lets you vị more with its cameras.

Overall, if you’re looking for the pinnacle of android phones, the S21 Ultra is it.It does, however, face stiff competition from the excellent OnePlus 9 Pro for the title of ultimate game android phone.
