2-minute Review [Positives]
  • Impressive sleek design, with a glossy gradient finish at the back
  • Quite lightweight at 155 grams, and due to its compact size, it fits into the hand perfectly
  • Fast fingerprint scanner - apart from unlocking the phones, it also allows you to take photos, accept calls, browse through pictures, and dismiss alarms using gestures
  • Fast face unlock
  • Modern, vibrant, 6.26-inch water-drop notch display, with good viewing angles
  • Sunlight legibility is especially good, unlike many other budget phones
  • Eye care mode allows for a comfortable reading experience at night
  • Infinix's custom XOS UI has a decent set of additional features, including XClub (customer forum), XHide (to hide pictures, videos), Phone Master app (to free up RAM to boost performance), gesture support, and a smart panel to the left of the first home screen
  • You can also do plenty of UI customisations with the XTheme app
  • Decent performance in day-to-day use with a modest Helio P22 (similar to Snapdragon 625) at the core
  • Decent triple camera setup on the rear - 13MP primary camera + 8MP ultra-wide camera + 2MP depth camera - one of the rare phones to offer a triple camera setup in this price bracket
  • Daylight shots are above average with good clarity and overall colour reproduction - the phone also does an excellent job of capturing macro shots
  • Auto-focus is fast
  • The quality of the wide-angle camera is decent too, and it gives you interesting picture framing options, especially when shooting landscapes
  • Good 32MP front camera - takes clear and crisp selfies - and is pretty decent in indoor lighting as well
  • Both rear and front cameras also have a decent bokeh mode
  • Overall, this is one of the best camera setups in this price bracket
  • Very good battery life with a large 4000mAh battery - you can expect a day and a half of use with moderate usage
  • Overall, despite a modest processor, the phone is one of the better contenders in the entry-level budget segment - with 2 key USPs - a good battery life and a good camera setup - if you are a light smartphone user, and not into gaming, it's certainly worth considering - if however you are more of a power user, you should look at alternatives from Xiaomi and Realme
  • In recent times, Redmi has adopted some very premium and stylish design aesthetics, and the Redmi 8 continues that trend, with great design and build quality
  • The ruby-red color variant especially looks stunning, and it is astonishing to see how far budget hardware has come
  • The phone also feels premium to the touch
  • The front is sharp and modern, with a dewdrop notch, and very similar to the Redmi 8A
  • The location of the fingerprint scanner at the back is near perfect - and the scanner is very quick as well
  • Decent 6.2-inch IPS display, the same as the one on the Redmi 8A - gets bright enough for outdoor use
  • Packs Gorilla glass 5 protection, which is a big bonus in this price segment
  • MIUI is one of the more refined and smooth Android skins around, and has a lot of customization/theming options - there’s ample features for power users - from gestures to the ability to switch around button layouts as well as a robust home screen customisation experience, you can really make the phone your own
  • Decent day-to-day performance, with the same Snapdragon 439 as the Redmi 8A (it's not really meant for gaming though)
  • Ok camera setup, at this price point
  • Outdoor shots look good enough with Xiaomi’s AI enhancements kicking in to deliver punchy images
  • The dedicated secondary camera enables portrait mode, and edge detection is decent
  • USB-C at an entry-level price deserves kudos
  • Phenomenal battery life with a 5000mAh cell paired with entry-level hardware - you will comfortably get 2 days of use
  • 18W fast-charging support (though a standard 10W brick is included in the box)
  • Overall, the Redmi 8 is another very good budget option from Xiaomi's camp, and along with the Realme C2/3i, will likely dominate the entry-level smartphone segment in India
2-minute Review [Negatives]
  • Due to its glossy finish, the phone attracts lots of smudges at the back panel (though Infinix does thankfully ship a TPU case in the box)
  • There is unfortunately plenty of bloatware too, as is often the case with such custom UIs
  • There is plenty of competition though that packs better processors in this price bracket (especially from Xiaomi and Realme), and will give much smoother gaming performance - so if you are a power user, then the S4 might not be your best choice
  • Low light performance of the rear cameras is average
  • Of course the glossy hardware catches on fingerprints (Xiaomi has thankfully tossed in a TPU case in the box, though)
  • Xiaomi has added a Redmi logo on the lower bezel and that feels like a bit of an overkill given there is Redmi already engraved on the back
  • It still continues to pack a lot of bloat though - you get 20-something pre-installed applications with wide-ranging requirements for user permissions
  • Limited dynamic range - the camera has a tendency to blow out highlights
  • Despite support for dual-pixel autofocus, the camera often hunts to get a focus lock
  • Images have some softness to them in anything less than perfect light - indoor images tend to be short on details
  • Videos are again fine in daylight, but not so much in anything less than that
  • Overall, the camera is not a particularly strong area for the Redmi 8
