2-minute Review [Positives]
  • Very good build quality
  • The metal frame is a nice touch, and enhances the overall design
  • Comfortable to hold, for a phone of this size
  • Good fingerprint sensor
  • Very good display - offers vibrant color output, good sunlight legibility and good viewing angles
  • Lenovo's UI over Android is one of the better UI skins around
  • Good speed/performance in daily use (although gaming performance could have been better)
  • Good overall front and back cameras
  • Thanks to Dolby Atmos, Wolfson WM8281 audio codec and dual front-facing speakers, loudspeaker output is brilliant and clear even in full volume
  • Audio output through headphones is brilliant as well
  • Good battery life
  • VR support
  • 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
