Call Quality

Calls on the Max come through clear and without issue for both the caller and receiver, though the earpiece and speakerphone could both use a few more notches of volume. Callers aren’t hard to hear on either, but peak volume is simply a few steps lower than we’d like.

Battery Life

Power for days, er, devices. Well, both.

Asus Zenfone 4 Max Review

5000mAh deliver some due gains here – not as much as we’d hoped, but enough for the Zenfone 4 Max to outpace most rivals. With normal use, this phone can usually last you into the two-day mark.

However, our custom test showed this hunk of lithium-ion to last for over 11 hours, which we were a little underwhelmed by. It’s certainly a long time, but we’ve had other devices like the AT&T Galaxy J7 Pop last over 12 hours with a 3300mAh battery, so it would seem Asus is still struggling with efficiency a bit.

The Zenfone 4 Max has the ability to spread some juice to your other devices, effectively functioning as a small powerbank (though this of course impacts battery life greatly). Plugging in the included USB OTG (On The Go) Cable will prompt you with an option to charge your devices with standard or rapid speed, though “rapid” is a relative term here. Our 3300mAh LG V30 estimated that a full charge would take over 6.5 hours in standard mode, and around 3 in rapid. A likely use for this feature would be to give a friend's phone a boost in case of emergency or to power up an accessory like a pair of headphones while on the go. Charging the Max itself takes over 3 hours, which is relatively slow, but understandable given the size of its cell.


Asus Zenfone 4 Max Review

We must say, Asus’ first of the Zenfone 4 lineup has us encouraged. Retailing for $200, competition is plentiful, but the Zenfone 4 Max makes a respectable case for itself. We love how fluid and snappy the device is, throwing in a gigantic battery didn’t hurt either. Better yet, it doesn’t feel like its packing 5000mAh in there judging by its weight, though it most certainly is. While the dual camera has its issues, it is certainly competent for the price point. The display's 720p resolution and washed out colors do make our hearts (and eyes) hurt when viewing anything other than full screen media or relatively large text, but all in all, we’re happy we met you, Zenfone Max 4, and we can’t wait to meet your siblings.


  • Massive battery provides solid battery life
  • Capable main camera for the price point
  • Prompt, smooth performance

  • Good value, affordably priced at $200


  • 720p resolution + 5.5-inch screen = grain in smaller images and text
