2-minute Review [Positives]
  • Stunning, beautiful design, that's a treat to the eyes - Vivo S1 is easily among the most well-designed smartphones to launch this year
  • There is a mesmerising dual tone finish on the metal frame, and a unique 'diamond lattice' design back, that reflects colors in the most interesting ways - this is the kind of smartphone that will definitely get you a lot of Wows from everyone around
  • It not only looks great but also feels great to hold and use thanks to the 2.5D design
  • Fast in-display fingerprint sensor
  • Dedicated Google Assistant button
  • Very good 6.38-inch AMOLED display - you will get deep blacks and punchy colors
  • Funtouch OS UI looks very similar to iOS, and is pretty feature packed, including a good gesture navigation system, and an 'Ultra Game' mode
  • Daily performance is smooth all-round with a Helio P65 processor (similar to the Helio P70, and Snapdragon 660), and most games run well too
  • Decent set of triple rear cameras - 16MP primary + 8MP ultra-wide + 2MP depth
  • The primary camera captures images with fairly good details
  • The depth camera helps with some decent portraits
  • The 32MP selfie camera is decent too, and does especially well with details (though the image softening algorithm is a bit too aggressive)
  • Outstanding battery life with a large 4500mAh battery paired with a low-power MediaTek Helio P65 SoC - you will comfortably clock 2 days of use
  • Bundled 18W fast charger
  • Beautiful, attractive, premium glass design (Gorilla Glass 5 on the front and back - a first for Realme), with a modern gradient finish at the back
  • The phone is also marginally smaller than the Realme X and is lighter too at 183 grams, which gives it a very balanced in-hand feel
  • The glass on the back is of the glossy kind, but it barely registers any fingerprints or smudges and it isn't very reflective
  • The in-display fingerprint sensor is snappy as is the facial recognition
  • Very good 6.4-inch FHD+ (1080x2340) Super AMOLED display with a dewdrop notch - it has vibrant colours, deep blacks, good sunlight legibility, and good viewing angles - one of the best displays of this price range
  • Also comes with Widevine L1 standard, which means videos on platforms like Netflix and Prime can be seen in crisp HD resolution
  • ColorOS is now more streamlined than before, and packs fast animations that helps the phone feel snappy - there are of course a number of add-on features too, compared to what you would get in stock Android
  • The UI also isn't ad-strewn as recent Xiaomi phones have tended to be
  • Very good performance backed by the powerful Snapdragon 712, which is one of the better mid-range mobile SoCs out there, especially for gaming - the Realme XT is able to run graphically intensive games like PUBG on default high graphics without breaking a sweat - of course day-to-day use is a breeze too
  • Thermal management is good too - the phone remains quite cool throughout gaming sessions
  • Excellent quad camera setup at the rear - 64MP primary + 8MP ultra-wide + 2MP macro + 2MP depth sensor - this is the first phone to launch in India with a 64MP sensor
  • Much like the popular 48MP sensor, the 64MP camera also works (by default) on a 4-in-1 pixel binning technology that combines four 16MP shots to offer one bright and detailed photo
  • The primary camera capture some really attractive photos in daylight, offering good brightness and clarity - with HDR enabled, the camera offers a wide dynamic range
  • The ultra wide-angle camera comes in handy if you want to capture a wider frame of view or want a different perspective on the subject (but there is some noise even in daylight conditions)
  • The camera also supports Nightscape (Night mode), which comes in handy in low-light conditions, and helps improve picture clarity
  • The Realme XT also does a good job when using Portrait mode - edge detection is excellent thanks to the dedicated 2-megapixel depth sensor and details are crisp
  • Decent video recording performance - image quality is good, and there is also stabilization at 1080p (but not at 4k)
  • Overall, this is now arguably the new camera champ of the under 20k category, coming out a bit ahead of the current leaders pack - the Realme 5 Pro, the Realme X, and the Redmi Note 7 Pro
  • Good speaker - verbal audio sounds clear enough even in max volume, and the audio is loud enough for you to hear the phone ring from another room
  • Very good battery life with a large 4000mAh battery - you will get about 1.5 days of moderate use
  • There is VOOC 3.0 fast charging support, which is great - you can charge up the Realme XT in about 80 minutes
  • Once again, like clockwork, Realme has launched another champion phone with the XT, that sets the benchmark for mid-range phones even higher
  • But more broadly, you won't go wrong with either of the current leading 3 Realme phones - Realme 5 Pro (cheapest, Snapdragon 712, but not a premium glass design, not a 'full-screen' display, not an AMOLED display), Realme X (pop-up selfie, and 'full-screen' AMOLED experience, but not a premium glass design, and 'only' Snapdragon 710), or the Realme XT (premium glass design, AMOLED display, best camera of the lot by a small margin, Snapdragon 712, but not a 'full-screen' display) - and you can chose one depending on your priorities
2-minute Review [Negatives]
  • It's on the cluttered side though, and does have some bloatware - so the experience is not as clean and simple as stock Android
  • More complex games like PUBG though are not smooth at high graphics settings - and here the phone loses out to the best performing phones of this price bracket that pack the likes of Snapdragon 675, and Snapdragon 710
  • The ultra-wide camera provides for versatility in shot framing, but the quality is average - details are low, and the overall image is muted
  • Low light performance is average too
  • Overall, the cameras are decent for the price bracket, but not really comparable to the top camera phones of this price bracket, like Redmi Note 7 Pro, Realme 3 Pro, Realme X, and even the Vivo Z1 Pro
  • Uses the old microUSB port, instead of the modern USB-C port
  • On it's own the Vivo S1 is a pretty good device, but it faces some real tough competition at the moment - the camera and the performance are not the best for the price bracket, though if your main priorities are a best-in-class design, and excellent battery life, it could still make a lot of sense
  • There is as usual some bloatware that comes pre-installed (but most of it can be uninstalled)
  • The macro lens is ordinary - you will be able to get really close to the subject, but detail levels in the images are low
