2-minute Review [Positives]
  • Good build quality, with a metal frame
  • The matte texture offers decent amounts of grip
  • Overall - slim, light, and easy to live with
  • The fingerprint sensor works really well and is very quick in authentication - you can also use it to lock apps and files - overall it's one of the best fingerprint scanners in this price bracket
  • Decent 5.2-inch IPS display, with good brightness levels, color saturation, and viewing angles
  • ColourOS interface on top of Android works very well, and has an iOS influence, along with support for various gestures
  • Pretty good speed/performance - cruises through basic apps, and light games quite well
  • In good lighting conditions the front camera is pretty good (one of the best in this price bracket), and the back camera is decent - though, in poor lighting conditions, both struggle
  • Decent speaker - isn’t the loudest for media when there’s a lot of ambient noise - but suffices for alerts and ring-tones
  • Decent battery life - generally lasts a full day with moderate use
  • High-end, premium metal design, and excellent build quality - befitting a much more expensive phone
  • Fast fingerprint reader
  • Impressive, bright display, with great color accuracy
  • MIUI on top of Android works great, runs fast, and has excellent theming and customization options, making it easy to find the look you want
  • Powerful Spandragon 625 chipset ensures smooth, effortless performance all throughout
  • Pretty decent camera - although it tends to produce photos a little bit on the soft side - but overall it's good, and a significant improvement over the Redmi Note 3
  • Good loudspeaker
  • Top-notch battery life - again, improved even over the already very good Redmi Note 3 - even with heavy usage, you can get close to two full days out of it
2-minute Review [Negatives]
  • The processor tends to heat up when taxed - this includes using the front camera for more than 5 minutes at a stretch
  • No fast charging support
  • Audio quality via headphones is average
  • Doesn't use the new USB-C standard
