Description

The Samsung Galaxy S21 Ultra 5G phone is epic in every way, with a striking new design, fastest Galaxy processor yet, a battery that goes all day and then some, and the first Galaxy ever supporting super smooth 120Hz screen refresh rate at WQHD+ resolution, it’s no surprise why Ultra easily lives up to its name. We know your life moves fast, and there’s a fine line between what makes a moment ordinary and what makes it extraordinary. That’s why Galaxy S21 Ultra 5G is purposefully crafted so you don’t need to choose between video and photo. With a single tap, you can pull super-clear stills — up to 33MP — straight from high-resolution 8K video. Use the 108MP high-resolution camera for still shots that come out crystal clear whether it’s day or night. Single Take AI transcends the usual restrictions of photo and video editing to capture life’s greatest moments, wherever they happen, in one single take, capturing images and video for up to 15 seconds. Experience the power of the Galaxy S21 5G series. Innovative and beautifully designed, Samsung 5G phones emphasize the brand’s dedication to the latest cutting-edge technology and next-generation connectivity. Enjoy more sharing, more streaming, more experiences, and more connections at lightning-fast speed. The Galaxy S21+ 5G does not currently support eSim in the U.S. Battery power consumption depends on usage patterns and results may vary. 5G speeds vary and require optimal network and connection (factors include frequency, bandwidth, congestion).

    • A mind-blowing and incredible experience.
Color: Phantom Silver Size: 128GB Style: S21 Ultra
I wanted to give this phone some full usage before I wrote my review and I can finally get into full detail. Before I jump into my pros vs cons let's just mention my personal final thoughts. Get it! Thought over. Whether you are transitioning from Apple to Android or just upgrading, this is without question the correct choice. With the latest chipset, processors, camera array, and intelligent software there are so many possibilities. Pros: 1) The battery life is absolutely insane. Now at first I wasn't sure how I felt about the battery. It seemed average after the first day or two of use. But something clicked half way through the third day of use. I had read from articles and watched YouTube reviews from TechTubers about this intelligent software. I expected them to be referencing the Ai. But it is so much deeper in that. This phone continues to monitor your usage and learn the way you operate with it. Pair it with a smart watch to perfectly shift usage and workload. At no point since purchase has this device seemed to struggle. I can comfortably say this is a 2 day phone easily. 2 days of continuous normal usage before needing a recharge. 2) The finger print reader is vastly improved from previous devices and can now be compared to the likes of devices like One Plus. Yes you will have to spend a good minute or so letting every point of your finger be thoroughly mapped out but it has proven to be lightning fast in response. 3) This camera...phew. if there was ever a single reason to choose the Ultra variant over the other two it is absolutely due to the camera. Laser focus, combined with smart lenses, and a true melody of beautiful spec options results in a user paradise. One could literally place a fruit, a leaf, and some random option side by side for a shot and notice visible suggestion. The fruit will display a food shot mode. The leaf will suggest aspect ratio options or even the ultrawide/ Auto-Focus macro shot mode. Truly mastering this camera will not only take time but also lot of practice, something I personally look forward to. 4) This may seem like something that at first should be obvious. But use of this device just truly feels so effortless and fluid. Everything works how I would want it to, and at just a speed that truly leaves you with a sense of relief. Cons: 1) Inevitably as with all Samsung products of course there is some bloatware. But from what I've seen it at least is not overwhelming. A few apps I know I'll never used sprinkled around. But those have just been compiled into a folder and forgotten about. 2) To some this may be a nuisance so it's worth mentioning. Although this device has an Android OS, it is noticeable the amount of strictly Samsung branded apps/Widgets available. It will take some navigating to better arrange your set up to one's preference. Especially when it comes to something such as utilizing the Google Play Store vs Samsung Store. 3) Third but maybe most importantly, given the circumstances everyone is facing due to Covid-19 the price is certainly a factor. Even with sales yes this is a price handset. Yes there was a price drop from last year, but that doesn't really soften the blow. 4) No charging brick. No matter how it is explained or reasoned, the absence of the brick is felt! On first charge I did use a prior usb-C to usb-a charger and wow.....talked about watching paint dry. There was absolutely no way that is truly the best option across the board for all the relevant phone companies. (Ended up buying a usb-c IQ charger from Anker. I think that was like $14 approximately. Definitely an immediate and noticeable remedy, thanks Anker for that save.) If one were to say is this phone worth the 999$-1200$ price tag. Honest answer, absolutely, depending on how one plans to use it. If you want the BEST experience out of the three variants (S21, S21+,S21 ultra) there is only one choice. However if that price point just isn't within your budget or path of purchase, I can still say the other two options will suffice also. ... show more

    • Best Galaxy phone I have ever owned!
Color: Phantom Black Size: 128GB Style: S21 Ultra
I switched from a Samsung Galaxy S8+ that I owned since 2017, and boy can I appreciate the upgrade! The phone is super fast, with great visuals and an abundance of features. Some of my favorite features include the Wireless power sharing, DeX (turning your phone into a computer with a tv or pc monitor), live caption (especially when I have to keep my phone on silent and want to watch something) and the amazing cameras, just to name a few. In regards to the cameras, the selfie camera is clean with great quality and the 100x zoom feature is in a league of its own. I will admit that going all the way to 100x zoom for pics will not give you best quality, but even at 20x zoom, it is amazing how this camera can behave like binoculars and pick up objects without any issues and maintain good clarity. The battery life is also quite amazing! I had to charge my s8+ 2-3 times a day with heavy usage, but I can easily go a day and a half with this bad boy. One negative I will say is that the phone does not come with a charger, which can be annoying if you don't already have any existing charger on hand. In my opinion, to preserve the quality of the battery, Samsung should have included a charger that was made for the phone, to prevent persons from possibly sourcing 3rd party chargers that may not be the best for this particular phone. On another note, I know some individuals are unhappy about the expandable storage not being a feature anymore, but as an S8+ user I never used expandable storage and will not miss it. With cloud storage and other ways to upload and store your data, it is not that big of a deal in my opinion. I can go on and on about this phone but I'll just conclude by saying that I am extremely happy with my purchase. Great job Samsung! ... show more
