Call Quality

More times than none, you’re going to ask you callers to repeat themselves frequently.

Voices through the earpiece exhibit a subtle robotic tone, but its volume output is ample enough to discern our callers under noisy environments. However, that’s not the case with the speakerphone – not only because of its weak output, but also due to the hollow voices it produces. On the other end of the line, though, our callers have no complaints about the rich and clear voices they’re given.


A big phone deserves a big battery! And boy is it long lasting.

Stuffed inside its body is a massive sized 3400 mAh battery, which permits us close to two days of normal usage from a full charge. No doubt, it’s pretty darn good, but it even reaches a great mark in our battery benchmark test – where it achieves an impressive tally of 10 hours 53 minutes.

We measure battery life by running a custom web-script, designed to replicate the power consumption of typical real-life usage. All devices that go through the test have their displays set at 200-nit brightness.

Looking at the overall package, we can say that the ZTE ZMAX is as generic as they get, but for a phablet, we’re content to know that it’s accompanied with an affordable price tag of $252 outright. Certainly, it’s the least features rich phablet we’ve come across, as it mostly provides a stock Android experience. Then again, for those looking for a competitively priced phablet that won’t break the bank, it provides enough quality elements to give consumers a valuable offering they can surely grow to love.
