2-minute Review [Positives]
  • Slick, beautiful, eye-catching gradient finish on the back (though the back is laminated plastic and not glass)
  • Fairly slim and light for a phone with such a large display
  • Oppo F15's in-display fingerprint sensor and face unlock work very well - face unlock even works well in dimly lit places
  • Very good 6.4-inch full-HD+ AMOLED display with a dewdrop notch and Gorilla Glass 5 protection - the colours are good, so is the sharpness - videos look sharp, with punchy colours, and the viewing angles are quite wide
  • Display gets adequately bright and is legible even under sunlight
  • You can watch Netflix and Prime in crisp HD resolution as Oppo F15 comes with Widevine L1 support
  • ColorOS is fairly streamlined, and packs fast animations that help the phone feel snappy - there are of course several add-on features too, compared to what you would get in stock Android
  • Decent performance with the MediaTek Helio P70 SoC (similar to Snapdragon 660) - day-to-day operations are smooth and you can even play games like PUBG Mobile on 'Medium' graphics setting
  • Thermal performance is good too - the phone doesn't overheat when using the cameras extensively or even playing games
  • Good quad-camera setup at the rear - 48MP primary + 8MP wide-angle + 2MP depth sensor + 2MP monochrome sensor
  • The primary camera shoots oversampled 12-megapixel stills - in daylight, it captures fairly detailed landscape shots, colours are vivid, detail is good, and there's little to no noise in darker areas
  • The wide-angle camera has autofocus, so stills taken have good detail, close-ups are sharp and detailed too - and if you get really close to your subject with the wide-angle camera, you'll be able to get good macro shots
  • Portrait mode works decently well with human subjects and you can adjust the level of blur before taking the shot - edge detection is decent and image quality is good, when shooting under good light
  • 16-megapixel selfie camera manages some pretty good-looking stills in daylight - skin textures are smoothen a bit but HDR works well and colours are well represented - with good amounts of artificial light around, it manages to get pleasing enough selfies even at night
  • Video quality is decent and there is stabilisation when shooting using the primary camera
  • The mono speaker gets fairly loud
  • Battery life is pretty solid, backed by the 4000 mAh cell - will easily last a day and half with moderate use
  • The Oppo F15 charges pretty quickly too with the supplied 20W Charger, about 88 percent in an hour
  • Overall, Oppo F15 is a decent smartphone - it looks good, and it impresses particularly with its slimness, light weight, and good display
  • Xiaomi has gone big on the design front this time - the Redmi K20 Pro has a glass back with one of the most evocative gradient patterns you'll come across on any phone today - it's both premium to feel, and stunning to look at
  • The gradient effect that kicks in under the right lighting condition is quite mesmerising
  • The front is modern and sharp too, with a 'full screen' notch-less display (the selfie camera is a 'popup' one)
  • Decent in-screen fingerprint sensor - reasonably quick and reliable
  • Gorgeous, 6.39-inch Super AMOLED display - easily one of the best panels you'll find in this price segment - it has vibrant colors and excellent contrast levels, and sunlight readability is great as well
  • Of course, the lack of a cutout means you get an all-screen front, and the minimal bezels at the top and bottom create an immersive experience when playing games or viewing videos on the device
  • MIUI, especially with it's recent improvements continues to one of the better, more cohesive custom Android UIs around - and it's packed with features like gesture navigation, anti-flicker mode, reading mode, second space, dual apps, themes, etc
  • The K20 Pro also adds the POCO Launcher on top of MIUI - which brings the Dark Mode and App drawer to the K20 Pro
  • Xiaomi is also rolling out a Game Turbo feature that prioritizes bandwidth and mutes incoming notifications when you're in a game
  • Top-notch flagship performance with the top-notch Snapdragon 855 chipset at the core - the K20 Pro is expectedly a performance beast - and gets the highest Antutu scores of any Android phone at the moment
  • Very good triple rear camera setup - the phone has a 48MP primary camera backed by an 8MP telephoto lens and a 13MP wide-angle shooter
  • Image quality is great in all sorts of lighting conditions - they look crisp, vibrant, and details are captured well
  • The ultra-wide sensor and 2x telephoto lens also produce generally good results
  • The K20 Pro also comes with a dedicated night mode that does the usual multi-frame processing, and the results are pretty good - it gets more light in, and makes things sharper
  • Decent 20MP popup selfie camera, with a good portrait mode
  • Overall, the rear camera setup on the K20 Pro is the best for this price bracket, and matches up well to more expensive phones like the OnePlus 7 and Asus 6Z
  • Has a 3.5mm jack, that a lot of flagships these days tend to skimp on
  • Loud (single) downward firing speaker
  • Very good battery life with a 4000mAH battery - combine that with a very efficient 855 processor, and you will comfortably get 1.5 days of use
  • Fast charging support - up to a cool 27W (a 27W capacity charger will however need to be purchased separately for super fast charging - that said, Xiaomi does include a still-very-fast 18W charger in the box)
  • Xiaomi has again hit the ball out of the park with the Redmi K20 Pro, providing a still-excellent-value successor to the super successful Poco F1 - this is the cheapest price point at which you will get the flagship Snapdragon 855, along with all the latest features of 2019 - full screen, popup selfie camera, and in-display fingerprint sensor - people who attach more value to the software experience though might still want to spend a little more and go for the OnePlus 7 or Asus 6Z, for a cleaner experience
2-minute Review [Negatives]
  • Oppo F15 is a tall phone - it's not the easiest phone to fit into a pocket
  • There is, as usual, some bloatware that comes pre-installed (but most of it can be uninstalled)
  • While the chip offers decent performance, this chip is typically expected in phones closer to the Rs. 10, 000 mark (such as the Realme 3) - the Oppo F15 feels underpowered, considering that the Realme X2 and Redmi K20 offer Qualcomm's superior Snapdragon 730 series SoCs at the same price
  • Selfie portrait mode doesn't work too well, unfortunately, whether it's day or night
  • There are few caveats here, like there's no option to shoot at the full 48-megapixel resolution - other features such as super-steady video and the ability to use Night mode for the selfie camera are also absent
  • In low light, image quality from both primary & wide-angle camera is average, details are weaker and there is visible noise in the darker regions - the ‘Night' mode helps brighten up scenes but the details don't improve much
  • No 4K video recording, which most of its competitors support
  • In low-light, video quality is noticeably worse with poor details and a persistent shimmer in the footage even with slight movement
  • Overall, camera performance could have been better, as two of its main competitors, the Realme X2 & the Redmi K20 offer better image quality
  • However, at this price, you're better off with either the Realme X2 or the Redmi K20 - both of which offer much better performance, even more premium build quality, and even more modern designs
  • Face unlock mechanism is a little clunky - you have to first wake the screen and swipe up for the camera module to engage (this might get sorted via a software update though)
  • One issue with MIUI in recent times is the ads in the interface & notifications - those are still there (though a little less intrusive) - and while there are ways to disable them, it's a technical solution that a lot of prospective buyers will not be aware of
