2-minute Review [Positives]
  • Flashy, colourful glass rear with a gradient tone along with Gorilla Glass 5 at the front and back make it feel as premium as it gets
  • The centrepiece of the rear design is the circular patch around the camera strip, with smooth finish while the glass around it looks frosted - giving the POCO X2 a differentiating look
  • The front looks slick, with all-screen, minimum bezels and punch holes for the front cameras
  • Lightning-fast fingerprint sensor (though, it's side mounted & can take some time getting used to)
  • Gorgeous, super smooth 120Hz Full HD+ IPS display - the added smoothness to transitions throughout the phone is love at first sight, every scroll and swipe will feel buttery smooth, and once you experience this, it is hard to go back to 60Hz
  • Strong brightness and great sunlight legibility
  • The POCO X2 has Widevine L1 from day one, allowing you to stream 1080p videos from Netflix and other streaming services
  • Poco's UI is identified as Poco Launcher as well as MIUI in different parts of the UI - MIUI has always been one of the most refined Android UIs out there, and continues to get even better - it offers a good combination of aesthetics, useful added functionality, lots of customisability, and optimisation - not only is there now an app drawer, but it has tabs that filter various categories of apps for easy access
  • Excellent performance, backed by the scorching Snapdragon 730G - the Poco X2 breezes through apps and games - heavy games run smooth, with PUBG Mobile running at high graphics as default
  • Good heat management - the phone doesn't get too hot in use, and only feels mildly warm when playing games or using the cameras for a while
  • Excellent quad cameras for the price - the primary 64MP + 8MP ultra-wide camera + 2MP macro camera + 2MP depth sensor
  • The 64MP main camera saves 16MP photos, and the daylight pictures came out excellent for the class - the resolved detail is plenty, the contrast is great, and the dynamic range is rather high with vibrant colours - you can shoot in the full 64MP resolution and the photos look quite good, with a downright impressive level of detail
  • The 8MP ultra-wide cam snaps good photos with enough level of detail and commendable contrast - very good ultra-wide shots for the class (though the quality is not as good as the main snapper, as expected)
  • The POCO X2's 2MP macro cam has autofocus, unlike the majority of the macro shooters out there, be it flagship or not - it is much easier to use, and the closeups are also good
  • The portrait photos are very detailed, have convincing blur and with some fine-tuning they can easily rival some of the best portraits from recent smartphones in this price range
  • Low-light shots are also good from both primary & ultra-wide cam - the night mode makes a considerable difference and you don't have to stand still too long - the night mode brightens frames and shows details that would have been otherwise lost in the shadows
  • Very good dual 20MP + 2MP selfie camera - there is enough detail in selfies, the colours are nice, and the contrast is good
  • Selfie portraits are good too - edge detection is quite accurate
  • Video recording is also good with good stabilisation, crisp details and smooth motion tracking
  • Overall, one of the best cameras you'll find in any phone around the price of the POCO X2
  • Good single speaker at the bottom - it's very loud and the sound is impressively deep and rich
  • Call quality on the Poco X2 is very good and there is barely any noticeable distortion or jarring while taking calls
  • Solid battery life with the 4500 mAh cell - can easily accommodate a day and half worth of moderate use
  • Impressive and unmatched 27W Fast charging for the price - the cherry on top is the included 27W Fast Charger which fills the phone in an hour
  • Offering high-end specifications at rock-bottom prices is the mantra POCO follows and the POCO X2 is so well priced it makes very good value for money phones like the Realme X2 and the Redmi K20 seem a little worse in comparison - the POCO X2 is the new value champ in its price segment - the processor, RAM, storage, battery, and cameras are all strong, and there's nothing to complain about in terms of build quality or the included accessories (though some people might struggle with the sheer size of this device and the ads in MIUI)
  • 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
2-minute Review [Negatives]
  • The POCO X2 is a humongous phone with its 6.67-inch display, making one-handed use potentially awkward - a bit heavy too at 208g
  • There is a noticeable shadow around the dual punch-hole cameras when displaying brighter content and it could be annoying - it could also be distracting when watching full-screen content
  • There's a lot of preloaded bloatware which sends you multiple annoying notifications each day asking you to download more through the company's own GetApps store - you'll see ads and promoted content in many of the default apps (though, it seems to have been toned down a little compared to before)
  • The camera app is a bit complicated for an average user, there is no clear way to navigate through all cameras - you have zoom controls for switching between ultra-wide and primary and different toggles for portrait and macro mode
  • 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
