I’ve been a LG user for the past 5 or 6 years. I had the V40 and the wireless charger failed. I couldn’t find a V60 to replace, so I started looking at Samsung. First I was looking at the S20 FE, which seemed like a great deal. But, since I’m a little slow to replace my phone, I wanted to look at the high end options. I came across this S21 Ultra, and I must say, it is a beast. It has more capacity that many laptops. I was able to time it right and get the 256mb model for 25% off, so it was a no brainer. I was also able to pair the Samsung pro earbuds for 50% off as part of the deal. I bought a stylus case, which I love having the stylus option. The only nit pick I would have so far has really nothing to do with the phone. I can’t find a screen protector that doesn’t have a thumbprint reading circle. Just annoying to have this brilliant display and an off set circle getting in the way. Overall, it’s a great phone…with many space age capabilities I will likely never utilize or even know how to use. The camera so far has really stood out to me. The zoom range is 007 like.

It’s hard to know where to really begin with reviewing this phone, because everything about it is simply amazing! But here goes:Build Quality & Design: So I was at first a bit apprehensive about the curved display because I wasn’t sure how I would feel about it (every other phone I’ve had had a flat display), but the curve is subtle enough that it’s very easy to get used to and actually adds a bit to the ergonomics of the design. The color looks just as stunning in person as it does in photos and the overall design of the phone looks incredible. The phone feels sturdy and the buttons have a very satisfying click to them and the fingerprint sensor has a great placement and works wonderfully.Display: The 1440p, 120Hz, display on this phone lives up to its reputation of being the best display you can get on a smartphone in 2021. The colors are vibrant and punchy, the clarity is top-notch, the high refresh rate (variable) really makes the phone feel snappy and quick. The touch sensitivity is also great and never feels like I have to put too much effort into moving around the UI.UI: I was a bit apprehensive of One UI as I hadn’t used a Samsung phone since the Galaxy S4 (and the days of the old TouchWiz) and I have been using Pixel/Nexus phones for the last 6 years. I have been pleasantly surprised, though, by how much it retains the core functionalities of stock Android while adding in features that are actually more useful than I would have guessed they would be (having Google One feed to the left of the homescreen is a great addition by Samsung). From the ease of connecting Samsung peripherals (I have Galaxy Buds+ and a Galaxy Watch 3) to the extended screenshot feature to the baked in screen record and everything in between, Samsung has really matured in their UI to now offer a lot of useful add ons while limiting the unnecessary bloat.Battery: This is the first phone I’ve had where I really can feel confident that my battery is going to last me the full day if I’m going to be out and about and away from the charger. Even with full 1440p and 120Hz enabled, I’m easily able to achieve 5 to 6 hours of screen on time with roughly 20 to 24 hours of total battery endurance. On days that I don’t push the phone as hard, I can get up to 8 or even 9 hours of screen on time and up to 2 days of overall battery endurance. Only on days that I’m scrolling through videos on TikTok, taking a lot of photos and videos, and really just having the screen on all day do I need to charge it even a little before the day is up (and even then getting it to even 50% is enough to give me confidence for hours).Camera: My last phone was a Google Pixel 3XL which, at the time, was basically the leading smartphone camera and could produce amazing shots every time. I wouldn’t say that this camera is as consistently and easily good, but the potential for great shots is even greater with this phone. Occasionally I have to take a few different shots to get the one that I want, but when I get what I want, it looks incredible. And this applies to all of the cameras, which brings me to the second point … The variety of cameras here makes the experience wonderful. I’ll frequently take 3 or 4 different shots utilizing all of the cameras to gain different perspectives and image profiles and nearly every time I get impressive photos from every lens (yes, even the 10x zoom camera can pull off pretty stunning imagery). The camera is definitely a high point for this camera, but you do need to be willing to work with it a bit more than you would on a Pixel or iPhone which are better quick point and shoot cameras, but lack some of the diversity of use that you can get with the Galaxy S21 Ultra.Conclusion: Overall, this phone is just incredible from top to bottom and is by far the best phone that I’ve ever owned. I would recommend this to anyone that is willing to pay a bit more for a premium device.

This phone routinely goes on sale on Amazon but a couple of reviews mentioning things like damaged goods on arrival, the phone not being unlocked for all providers, or even the phone having bootleg software installed on it nearly scared me off. Fortunately, when I got my phone, it was in brand new condition and was in fact able to be used with my provider (AT&T). One popular review mentions the phone came with bootleg software installed as the startup screen simply says Samsung without the model name beneath it in addition to having the Android mascot appear at the bottom. As it turns out, this is in fact just the regular startup screen of the phone, a fact that I looked up multiple videos of because I was scared when my phone had that same startup screen.The battery life is very good, dropping maybe 10% or less overnight with multiple applications open in the background compared to the 40-50% my S7 would drop overnight. This phone is also incredibly fast; nearly every app or web page I pull up loads instantly, which was again a huge shock after upgrading from my S7. Speed tests indicate that the 5G capabilities of this phone also work very well. The fingerprint reader is excellent, taking only one press most of the time and very rarely requiring two (even with a screen protector as well, although I do not use a tempered glass screen protector, so I cannot speak for how well it works with one of those). Overall this is a phone I highly recommend buying if you haven’t upgraded in a few years and if you can get it on sale. In the past month I’ve seen it go on sale for $999.99 twice and it was even $924.99 on Prime Day. Just make sure to not cheap out on a case and screen protector as well.

I start saying “don’t pay attention to those 1-star reviews, which complain about no dual SIM support, no microSD, no charger, heaviness, etc.” We know the specs of what we’re buying, if getting a microSD slot is paramount for some, they shouldn’t have bought the S21 in the first place.My experience with this phone has been excellent, having had almost every Galaxy S/Note iteration since 2010, S21 Ultra is no doubt the best smartphone Samsung has ever produced. Great high refresh QHD AMOLED display, solid built, powerful camera system with best-in-class zoom, improved fingerprint sensor, butter smooth interface, more-than-capable Snapdragon chipset, best battery life of any Galaxy S (one day with heavy use and two with light use). Yes, it is a heavy device but nowadays even midrange phones are weighting around 7 oz. Of course it’s not perfect but it’s close, low light photography could be better and should improve with software updates, speakers are just OK for a flagship, it ought to have faster charging capability (45W at least).That’s my summary, if you buy the S21 Ultra, you won’t be disappointed.

Galaxy s21 ultra.This phone is amazing. I just upgraded from the iPhone 11pro. I got tired of my iPhones always breaking and having software issues and having to send them in to get replaced. Decided to go with Samsung because I’ve always heard great things about their phones and now I can personally say that this phone has blown me away with how more technologically advanced it is compared to iPhone. The camera and screen resolution especially but also just all of the features and things you can do with this phone are all incredible. I’ve only had it a few days now so I can’t attest to the reliability but it feels like it’s made with quality materials.

This is a great phone. I’m still trying to figure everything out on it. I’m coming from a Xiaomi (great phone too) phone so it’s gonna take me a few days to learn what I need to know. I’m completely satisfied with the change. I’ll only buy Xiaomi or Samsung phones from here on out. The camera is unbelievably great. They battery is good too but I’m still trying to figure out how to make it even better. This phone is super fast and everything looks amazing on it. Gaming is great too. It was simple to set up. If you are looking for a new phone then I highly recommend this phone. Remember you can’t expand the memory so choose what is best for you. That is really the only downside to this phone but I knew that ahead of time so I really can’t complain about it. Also I think all big name brand phones are over priced but this particular phone does everything you need and more.

1. Phone. Let’s not forget it’s initial purpose of existence… communication. I think it’s a Verizon thing, but the sound quality of phone calls is uniquely satisfying and clear.2. Signal. For carrier signal, for me, it is much better than my previous 4G device, the Galaxy S8+. I cannot mention much about the 5G signal nor it’s data speeds as the network is still fairly limited in my area. Wifi is dramatically improved. Bluetooth, NFC, GPS, Wifi Hotspot, and Wifi Direct seem extremely responsive and equally great.3. Performance. This thing is a power house. With the dual quad core CPU’s, Snapdragon 888 SOC, Qualcomm Adreno 660 GPU, 120 Hz AMOLED display, everything is snappy and quick.4. Battery. 5000 mAh ought to seem like a lot, and it is.. Though with the performing hardware mentioned above, don’t expect a solid week’s worth of gaming in a device of this caliber. Power saving features exist for a reason. Changing your display output to 720, enabling an aggressive power saving mode, setting your screen brightness to the lowest value, and limiting yourself to calls only, you can get several days of use on a single charge. Without those energy saving measures, expect about half to a full day’s use on a single charge.5. Charging. It lacks a 25 watt super fast charger, or any charger at all. It does come with a USC type C to type C cable though. You get five varying levels of charging: two with wireless, three wired. For wireless, standard and fast charging. Wired, standard, fast, and super fast. With super fast, it can fully charge a dead device in about an hour. The slowest charge is around three hours. For longevity, don’t super charge unless absolutely necessary.6. Camera(s). 12,000 x 9,000 pixels is a lot of depth. About 35 MB per photo at 108 megapixels. There are Pro modes for video and stills as well. 8k at 24fps? I don’t get that one. But a solid 60fps for 4k video is outstanding. Add the stability feature and you’re now a video director and professional cameraman. The video and photos are beyond excellent. The 100x zoom is a comedic gimmick. Let’s get that out there. The HDR low light photos are superior to any device I have used. The video has no HDR capture support ): . Shame. The macro support is fantastic. Crisp, clear images in just about every shot.7. Storage. This one is tough. Samsung recently ditched expandable memory, which really upset me initially. It’s a selling point. If you intend to use lots of apps, take lots of photos, videos, download oodles of stuff… choose wisely. If you don’t have a computer or infrequently dump your device data to a cloud service or another PC, get more storage. I settled for the middle ground at 256 GB. After my apps are setup and good to go, I have about 190 GB of usable storage remaining. Plenty… for now.8. OS. I could sit here and talk about Android 11 and Samsungs TouchWiz UI, but it won’t matter. Software gets updated now frequently than hardware, and will forever change. The software on this device is only slightly different from similar devices. It’s much better than previous revisions. Both Samsung and Android allow for some more aggressive customizations on newer devices. It’s nice, to say the least.9. Features. Power sharing is nice, but with its beastly hardware, you’ll likely not want to share your precious battery with anyone, nor anything else. It’s a neat, almost useless feature to me. DEX by Samsung is still an infant. Don’t even mess with it. Link to Windows is cool, but needs some fine tuning to be better. You still have a flashlight. That’s cool. The fingerprint reader is neat, but tricky to learn since it’s behind the main display. It takes a while to get used to. I wish we could add more than four fingerprints, or allow more passes for each finger. It isn’t always consistent in every condition. This phone supports the S-pen and select S-view cases as well. They’re not included, and are fairly pricey accessories.10. Design. When LG started advertising the Chocolate with Christina Aguilera singing in the background, I knew phones were competing with cars for our attention in ads. The corners, surfaces, feels, looks, sharpness, and radiant elegance is near perfection. Dat camera bump, though…. I almost wish they made a thicker battery, maybe 8, 000 to 10,000 mAh, to craft a better balance and prevent the offsetting camera bump from existence. Why does the edge panel have a bubble leveler for this device? You can’t use it! That’s just silly. The camera pimple…I don’t like it. YouTube is the only platform to support HDR10 for a device like this, and it looks beautiful. Super bright. Super sharp. Super..darn… that pimple is quite noticeable and slightly breaks immersion. This phone weighs less than my previous Galaxy S8+. It’s only slightly larger as well. That’s impressive to me.Is it worth a grand? Considering the fact that I paid as much as I did for my S8+? Yes. It’s a considerable upgrade. I highly recommend a case. Especially one that can add balance as to rid itself of the camera bump. A screen protector is also recommended, as with any device with such a large display. I don’t care that it has the latest Corning Gorilla Glass on it. Micro scratches are a thing. And with a display like this, you will want to preserve its perfections, even if it has an adolescent pimple on one end.

I upgraded from the Galaxy s8 to the S21 Ultra with 256 gb of storage and 12gb of ram. I will start off by saying go with the Ultra or the base, you pay $200 extra for half an inch of screen on the plus (this is called decoy price, you see this at movies where the popcorn medium is only 1 dollar less than the large, but is 3 more than the small, so you might as well go large.)I’ll give more detial at the end.Camera is super high quality, zoom is incredible. Front camera even takes good pics (I mean I looked good, so should you)Processor is as advertised, insanely fast, even at the standard limited benchmark (there is an enhanced processing mode to take away cpu 70% limit). Desktop mode is great, this phone is almost as fast in Dex as my actual Acer laptop.Battery life is phenomenal, can get 2 full days out of 1 charge if you use the phone less than 4 or 5 hours a day at 1080p res.1440p, super clear and one of the bargaining point for the Ultra over the base. The refresh rate of 120 hz is incredible, I spent the first 10 minutes just swiping on the phone in awe of this. The ultra is also the only version with the curved screen,, the s21 and plus have flat screens.. This phone does an excellent job of cooling, even witha case on. (FYI heat causes the major wear and tear on the internal components like the cpu, so better cooling means better lifespan and performance).Customizable routines allow you to add features to your phone, from automatically silencing when you show up to work or school, automatically going into power save mode at certain times like when you are asleep, or even for when you turn on your Bluetooth headphones your phone can automatically switch to 1440p resolution and turn Dolby atmos on movie mode sound. Dozens of scenarios or time stamps for each feature.If you are the friend that walks on the grass, don’t worry about bringing that bulky charger for when your friends’ phones are about to die, this phone can wireless charge other devices (will stop charging when the phone drops to 30% minimum).If you are concerned about no color options, just remember, I had that beautiful orchid gray s8, and who got to see it? Nobody, because it was hidden behind a lovely teal case for 4 years.If the fact that Samsung dropped their charging from the 45w of the s20 series to a 25w for the s21, rest assured, there is very little added time for charging, and the 25w is less volatile than the 45w. This means, charging does not get the phone as hot, and the battery will have a better lifespan since slower charging is better long term.If you multi task a ton and/or save tons of files, consider spending the extra money to get the 512 gb edition, as it comes with an additional 4gb of ram (16gb total).Ram is what is used to have tabs open, so more ram means more tabs open while still maintaining speed and smoothness. The s21 ultra also has Spen support (need a case that can hold it).Why the ultra or base and not the plus?The s21 has a better ppi (pixel density, higher the density, better the picture) than the s21 plus. They both have the same 8gb of ram, the same storage sizes, same resolution, same cameras, same material, same flat screen, the same backwards wireless charging capability (same for ultra), etc. The only difference is the screen size and that the s21 plus has a 4800 mAh battery while the s21 has a 4000 mAh. The ultra however, offers higher resolution, much higher ppi, the larger screen, larger battery than both (5000mAh). The ultra has much more powerful camera as well, the curved screen, camera features and settings. So if you want all the features and performance and screen resolution (I like the stream movies on my lunch breaks) then go with the Ultra, if you just want to upgrade to the newest and fastest phone, and you don’t need to have 100000 tabs open, get the base s21.

If you’re coming from an older galaxy device as I was from the s8+ this upgrade is a HUGE jump. I was hesitant at first due to the lack of SD card expansion and the removal of the iris scanner but really, I’m not missing my s8+ at all. The performance is just insane. Processor speed geekbench results are 2-4x the s8+. The display is absolutely gorgeous and the cameras are as well. She’s a bit thick and heavy but not in a bad way. The phone feels great, solid in your hand. Very pleased with my decision to finally upgrade. I think the sweetspot may be 3-4 years in between upgrades as you really get A LOT out of it at that point. The differences generation to generation tend to be minimal.

The s21 Ultra is best smartphone on the market, 1440p 120fps oled makes for a screen that looks so good with its high pixel density. blacks are super black, this screen goes really bright too in the sun. really smooth too. one of the best screens I’ve ever seen ever. newest 5nm snapdragon 888 processor makes it really fast and efficent. best main camera and telephoto camera ever. bettery life is ok, get like 6 hours sot with 1440p enabled depending how heavy you use your phone. just make sure to go throught the setting and change from fhd+ to qhd+ to get the sharpest display.only thing is its on the large side but doesn’t feel that large because its taller than wider.don’t get anything less than 256gb because there’s no expandable storage.
