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
  • Beautiful, attractive, premium glass design (Gorilla Glass 5 on the front and back), with a modern gradient finish at the back - identical to the Realme XT
  • 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 (the fastest in this price bracket), as is the facial recognition
  • Excellent 6.4-inch FHD+ (1080x2340) Super AMOLED display with a dewdrop notch - again same as as the Realme XT - 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 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
  • The UI also isn’t ad-strewn as recent Xiaomi phones have tended to be
  • Excellent, butter smooth performance backed by the powerful Snapdragon 730G (15% faster than the Snapdragon 730 in graphics performance), which makes the Realme X2 one of the best-performing phones in this price range, especially for gaming - even ahead of the Redmi K20 in benchmarks - the Realme X2 breezes through pretty much any task you throw at it and is also an excellent smartphone to game on - even heavy games like PUBG Mobile, COD Mobile run consistently smooth
  • Very good quad-camera setup at the rear - 64MP primary + 8MP ultra-wide + 2MP macro + 2MP depth sensor
  • The primary 64MP camera 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 X2 also does a very good job when using Portrait mode - edge detection is excellent thanks to the dedicated 2-megapixel depth sensor and details are crisp
  • Good video recording quality - image quality is good, and there is also stabilisation at 1080p (but not at 4k) - video bokeh feature also works very well and it can maintain a very accurate edge detection with busier backgrounds (low light video recording could have been better though)
  • Very good selfies from the 32MP front camera - it captures very good portrait selfies with crisp edges and background properly blurred - there is also night mode for selfies and it works pretty well
  • Overall, Realme X2 has one of the best cameras under 20k category, arguably right behind the Redmi Note 8 Pro & Redmi K20
  • 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
  • Good battery life with a large 4000mAh battery - you will get about 1.5 days of moderate use
  • There is super-fast, class-leading 30W VOOC 4.0 fast charging support - you can charge up the Realme X2 from 0 to 100% in an hour with the supplied charger
  • Realme has yet again managed to craft an excellent package with the Realme X2, especially if you want to do heavy gaming - Realme’s strategy of bring high-end features like the 30W VOOC Charging & in-display fingerprint sensor to a mid-range phone makes the Realme X2 a very compelling phone to buy
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
  • 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
  • Having said that, the competition is neck-to-neck - there is Redmi K20 which offers a full notch-less display, even more polished design and slightly better camera at a similar price (at the cost of slower 'fast' charging) - and if you are on a tight budget, the cheaper Redmi Note 8 Pro is also a very good option as long as you don’t care about the AMOLED display and an in-display fingerprint sensor
