  • Supports 20W wireless charging.
  • The edges have been greatly exploited compared to the Mi 8.
  • Notifications bulb supported.
  • The battery is charged in a very short time due to the 27 watts and 20-watt wireless charging.
  • Supports Slow Motion imaging with FHD quality at a rate of 960 frames, the same found in the Mi Mix 3, surpassing that of the S10 +.
  • The performance of the built-in fingerprint sensor on the screen of the fifth generation is 25% stronger than the fourth generation in the Mi 8 Pro and Mi Explore.
  • The phone's performance is the strongest so far and even surpasses the S10 / S10 +, Mate 20 Pro, and OnePlus 6T phones.
  • The strongest performance you will find among the most powerful phone on the PUBG game due to the strongest graphic processor among all competing phones in a big way.
  • The rear cameras are the best they can be, as they are one of the best-rated cameras on the Dxomark website, outperforming the Apple iPhone XS Max, HTC U12 +, and Note 9, and tying with the Samsung S10 Plus cameras.
  • The screen offers satisfactory performance, as it offers the same pixel density as its previous Xiaomi Mi 8 phone, and it also comes with the latest protection layer on the screen.
  • The notch has become better and less compared to last year with the Mi 8, but it is not the best, as the S10 surpasses it well.
  • Water and dust resistance is not certified.
  • Because the phone came from glass, we found that it could slide very easily.
  • It does not support external memory, unlike the S10 + and S10, unfortunately.
  • The rear cameras are very prominent on the back of the phone.
  • Cameras lack OIS, and we don't know why.
  • The battery is not the largest in the price category and there are phones that come with a larger battery, but it still offers satisfactory performance due to the energy-saving processor, up to 5 hours open screen.
  • It does not support 3.5mm headphones input nor does it support the stereo speakers.

    I found this phone very efficient and everything that I asked of it to do My only regret was that I did not get one with a larger storage capacity, I bought this phone to replace a Samsung which before that I was a devout Samsung user but got tired of Samsung’s games every three to four years when they would put out some kind of virus or update in my opinion that would corrupt my phone to have me purchase a new one.
