Asus ZenFone 3 Ultra (ZU680KL) Review

  • Good
  • Premium build quality
  • Great screen
  • Strong battery life
  • Good cameras
  • Bad
  • Mid-range specifications at flagship price level
  • Heavy and bulky

What is the ideal size for a smartphone? The answer is of course subjective, but there has been an obvious trend towards going larger. Models with 5.5-inch screens have dominated the Android market for quite some time now. In fact, it’s pretty hard to find a mainstream Android model with a screen smaller than 5 inches, but there are quite a few larger models at various price levels. We recently reviewed the mid-range Lenovo Phab 2 Plus (Review) and Xiaomi Mi Max (Review), and today we have with us the gargantuan Asus Zenfone 3 Ultra.

Asus ZenFone 3 Ultra (ZU680KL) Summary

The Asus ZenFone 3 Ultra might replace both your smartphone and tablet. Its 6.8-inch screen makes it heavy and unwieldy, although the company has done a good job with design. The display quality is very good, even though the resolution could have been higher. Battery life is also a highlight. Camera quality is strong, but you can get a lot better from similarly priced Android smartphones.
