2-minute Review [Positives]
  • Jazzy, eye-catching back panel design with gradient finish and the unique diamond-shaped camera module
  • The slim profile of the camera module barely protrudes from the back
  • The in-display fingerprint sensor works well
  • Face unlock is present too, which is reliable (though, not as quick as on the other phones at this price level)
  • Vivid, crisp 6.38-inch full-HD+ Super AMOLED display - the colours are also very punchy thanks to the AMOLED panel, and text and icons are adequately sharp
  • The display gets very bright, making it easily legible even under direct sunlight
  • Widevine L1 DRM certified - you can watch Netflix and Prime in crisp HD resolution
  • Funtouch OS based on Android 9 Pie looks very similar to iOS, and is pretty feature packed
  • Decent performance powered by the Qualcomm Snapdragon 665 - it handles multitasking well and regular usage is smooth
  • Decent set of quad rear cameras - 48MP primary + 8MP ultra-wide + 2MP macro + 2MP depth camera
  • Close-ups are good, with good bokeh and details in objects
  • In bokeh mode, the Vivo S1 Pro's depth camera does a decent job of detecting edges, and blurs out the right areas - colours and details are also good
  • The macro camera is also handy at times, and lets you get very close to the subjects
  • Very good 32MP selfie camera - it captures detailed photos when shooting under ideal light - results are fairly good even when shooting against the light
  • The Vivo S1 Pro packs in a 4500 mAh battery, which easily lasts for 2 days of moderate use
  • Overall, the Vivo S1 Pro is a decent pick if all you want is a stylish design, good battery life, and a punchy display
  • Eye-catching, attractive design, like a lot of recent Vivo and Oppo phones - the back of the phone is all sorts of interesting, with gradient style colorways - it’s definitely going to turn heads
  • On the front, the phone is all screen - and looks really damn good - it's an expansive viewing field that is as close to the concept of all-screen devices as we’ve gotten to so far
  • This is not a small phone, but the gently curved edges and back make it very comfortable to hold - Vivo has also done a really good job with weight distribution, and the phone nestles very easily in the palm of your hand
  • There’s a direct shortcut for Google Assistant on the left side of the phone - double clicking the button activates Google Lens or Vivo’s own Jovi image recognition
  • The in-display fingerprint scanner works perfectly well
  • There's also perfectly capable face recognition that uses the unique pop-up selfie camera (takes less than half a second to pop-out)
  • The large, vibrant, 6.23 inch display Super AMOLED display of course stands out - the screen is nice and sharp with crisp text rendering - it's also excellent for media consumption, with no notch to disrupt a clean experience - it also gets sufficiently bright for outdoor use in direct sunlight
  • On it's own, FunTouch OS UI is pretty functional, customizable, and smooth
  • The Snapdragon 675 is a pretty good performer, just a notch below the 710 is real life use cases - navigating through the interface and jumping between apps is very smooth, and playing games like PUBG is also a very enjoyable experience (even with graphics set to high)
  • Pretty decent set of rear cameras - especially in day light - the Vivo V15 Pro has three different rear camera modules - there’s a 5MP depth-sensing camera, an 8MP wide-angle sensor and of course a 48MP primary camera - while you can shoot full resolution, 48MP, shots from the camera, it works best when pixel-binned to 12MP
  • Particularly useful is the ultra wide lens - which gives a really nice way to get a very different perspective
  • Very good popup selfie camera - that pops out in under half a second - and produces some good quality images in most lighting conditions - there's also a very powerful beauty mode, if you are into that sort of stuff - overall, as far as selfie cameras go, this is one of the best, not just in this price range, but on any smartphone
  • Good battery life with a 3700mAh battery -with moderate use the phone can give you up to 1.5 days
  • Supports fast charging with Vivo’s “Dual Engine” charging - you get a 25 percent charge in 15 minutes - and a full charge in about 1 and a half hours
  • Overall, the V15 Pro is another great, innovative device from the Vivo camp - you can go for it if you want a good balance between performance and design, and an amazing, true 'full screen' display - if on the other hand you are looking for the best rear camera experience or the best performance - look instead at the Poco F1, OnePlus 6T and Honor View 20
2-minute Review [Negatives]
  • The Vivo S1 Pro feels a little chunky at 8.68mm thick
  • The back isn't glass, as Vivo still uses laminated plastic
  • Having said that, the interface is unnecessarily complicated - swipe-up gesture to access system shortcuts is confusing, since it's in the notification shade in stock or other Android UIs
  • There's a lot of bloatware preinstalled on the Vivo S1 Pro (though the third-party apps can be removed)
  • Heavy games such as PUBG Mobile however struggle to run at a smooth frame rate even at the Low graphics preset
  • This isn't a bad processor, but it's typically now found in phones closer to the Rs. 10, 000 mark, such as the Realme 5i
  • In daylight, the primary camera manage to capture average-looking landscape shots - images lack depth, objects at the sides of the frame also have a bit of grain - HDR kicks in when needed, but the end result isn't always very good - some images have a very cool, bluish hue to them, which look unnatural
  • The wide-angle camera offered a nice perspective, but colours weren't very accurate
  • Low-light photos are just strictly average - focusing is a lot slower in the dark, and it takes a second or two longer to save each photo - there's no dedicated night shooting mode either
  • No option for a background bokeh effect with the front camera
  • Videos can only be recorded at up to 1080p, which is not great, especially at this price - there's no stabilisation either, which is a big letdown
  • Low-light video is not very good, from both primary & ultra-wide lens - has lots of grain as well as weak details
  • Overall, rear cameras are nothing special - you will get better outcomes with the Realme X2 or the Redmi K20
  • The single speaker doesn't get too loud and the sound is a little tinny
  • Vivo uses its Dual Engine Fast Charge feature, but the 18W charger isn't the fastest - charging the phone completely takes about two and a half hours
  • If you'd prefer a more well-rounded phone though, we suggest looking at offerings from Realme and Xiaomi instead, such as the Realme X2 and the Redmi K20, which have much more powerful SoCs
  • The volume rocker is a little bit too high up, sometimes requiring a little shimmy to reach
  • The location of the fingerprint touchpoint for the in-display scanner is a little too low on the screen and you might find yourself having to bend your thumb over a bit too much to unlock the phone
  • Coming as the the Vivo V15 Pro does with a glass back, the usual caveats apply - the phone is slippery, and is nearly impossible to keep the back clean of fingerprints and smudges (having said that, Vivo is throwing a well-designed case in the box, which takes care of these issues)
  • The lack of Widewine L1 certification means that the phone can’t stream HD videos on Netflix or Amazon (they will stream at 540p resolution)
  • It is still pretty much a clone of iOS though - and that might not be everyone's cup of tea
  • It also packs a bunch of bloatware (mostly un-installable, thankfully)
  • It's also somewhat buggy at places - for instance the aggressive battery management means that it sometimes force closes apps unexpectedly
  • It does get slightly warm though, when put under heavy continuous load
  • Sound quality during video recording is pretty average
  • Overall, the rear cameras are good, but they are still a notch below the top competitors - the Pocophone, Honor View 20 and OnePlus 6T (on the other hand, the front camera of the V15 Pro is arguably better than that of these three)
  • Uses the old microUSB standard, instead of the modern USB-C
