ASUS Zenfone 5z Vs OnePlus 6 Vs Xiaomi Mi 8: Design, Specifications, Camera & More Analyzed


We've more than settled into 2018 and the year has provided us with some fantastic smartphones and changing market dynamics. Chinese manufacturers are on the rise and continue to provide established companies such as Apple and Samsung with tough competition in Eastern markets.

But this post isn't about the future or about the two mobile behemoths. Rather, it's about ASUS, OnePlus and Xiaomi - all three of which have excellently spec'd devices available. So, if you're stuck between the three or need more information for a purchasing decision, head over below for more details.

ASUS Zenfone 5z Vs OnePlus 6 Vs Xiaomi Mi 8: Design Comparison Gives The Mi 8 A Slight Edge In Thickness

Before we get to the aesthetics and build materials, it's relevant to first take a look at all three devices' dimensions. These are:

  • 153x75.7x7.9 mm for the ASUS Zenfone 5z.
  • 155.7x75.4x7.8 mm for the OnePlus 6.

Therefore, the Xiaomi Mi 8 is the slimmest device out of the three and the ZenFone 5z is the widest. All three smartphones have their thickness in the 7.5-8.0mmballpark, so you're unlikely to feel a difference at a cursory glance or everyday usage.

Moving towards build material, the Xiaomi Mi 8 and the OnePlus 6 have glass at their front and back, with the gadgets being encased with an aluminum frame. The Zenfone 5z, on the other hand, has an aluminum back and body. The Zenfone is also the lightest gadget of the three, weighing in at 155g. For comparison, the Mi 8 and OnePlus 6 weigh in at 175g and 177g respectively.

Moving towards ports, the Xiaomi Mi 8 is the only device out of the trio that does not feature a 3.5mm earphone jack - a fact that also contributes to its slim form. All three gadgets have rear fingerprint sensors and vertical rear dual cameras, with the major difference being the sensors' location.

None of the three devices carries a solid IP rating, so you'll need care when exposing them to dust and water. Finally, moving towards the color options. The OnePlus 6, Xiaomi Mi 8 and ASUS Zenfone 5z are available in the following colors:

  • Xiaomi Mi 8: Black, Blue, White, and Gold.
  • OnePlus 6: Midnight Black, Mirror Black, Silk White, and Amber Red.
