Call Quality

We've got no major complaints when it comes to voice-call quality on the ZenFone 3 Zoom, and our only issue is more with the phone's physicality: it's just a quite wide handset, and not one that feels super-comfortable holding to your ear for any extended period of time.

Battery Life

A huge battery seems to be at odds with power-hungry hardware

Besides the dual camera, the other real noteworthy feature of this phone's hardware is its huge battery: a big-honking 5,000mAh component. That's incredible to see on a phone, let alone one as relatively slim as this model.

The good news is that the combination of this giant battery and the power-conservative Snapdragon 625 chip results in some killer battery life – and in our custom test, we clocked over twelve solid hours of screen-on time.

Recharge times are quite slow, to the tune of over three hours, and while that might be expected with a 5,000mAh battery, it's a situation not helped any by a regular 5V, 2A charger – no special fast-charging tech present in the box.


Asus ZenFone 3 Zoom Review

The Asus ZenFone 3 Zoom is a smartphone in an uncomfortable position. None of its big features – neither its dual cameras nor its giant battery – end up really panning out in quite the way Asus clearly hoped, and while they don't utterly disappoint, they're far from the major selling points they were meant to be.

But maybe that's neither here nor there. If we ignore the marketing hype, and don't let ourselves get distracted by what we think all these specs should come together to offer, the ZenFone 3 Zoom really is a quite solid smartphone. It's got decent performance, really good (if less than out-of-the-park great) battery life, and a respectable camera with more flexibility than the shooters on a whole lot of phones – including some more expensive models.

What's best, though, is the pricing, and at $330 or less (as we go to publish, Best Buy has the phone for just under $300), you're getting a fair amount of smartphone for your money. And while you could pay more and come home with a phone that maybe sees things through better than the missed potential we get the ZenFone 3 Zoom, it's a good enough deal that it's going to be difficult to feel too upset about going with this Asus hardware.


  • Solidly day-long battery life
  • Good value
  • Flexible camera hardware


  • Camera software needs work, low-light performance unsatisfying
  • Audio a bit of a letdown
  • No waterproofing
  • Dated design
  • Battery this big feels like it should last even longer
