Design
- 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
- Oppo F15 is a tall phone - it's not the easiest phone to fit into a pocket
Display
- 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
Software
- 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
- There is, as usual, some bloatware that comes pre-installed (but most of it can be uninstalled)
Performance
- 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
- 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
Camera
- 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
- 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
Audio
- The mono speaker gets fairly loud
Battery
- 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
Verdict
- Overall, Oppo F15 is a decent smartphone - it looks good, and it impresses particularly with its slimness, light weight, and good display
- 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
