Call quality


Call quality with the Xperia X and Xperia Z5 is highly similar, regardless of whether you're looking at earpiece or microphone performance.

With both, the earpiece is superior to their respective microphone, delivering relatively clear and tonally correct voices that we immediately recognize. In the big scheme of things, we'd rank them better than average.

On the other end, however, things aren't as good. The microphone lacks power, so the other side will have trouble making out everything you say in a busy environment. For what it's worth, however, the Xperia X's unit is slightly more powerful.


Battery life


In terms of total capacity, the 2,900mAh cell of the Xperia Z5 has the lead over the 2,620mAh unit of the Xperia X. But as you should know by now, numbers are just numbers.

Indeed, we found the numbers to be unrepresentative of our experience, with the Xperia Z5 offering worse battery performance with perhaps a 10% drop in longevity compared to the X. Not a massive advantage for the newer device, sure, but still something to keep in mind. Obviously, this ratio can vary wildly depending on what your typical usage looks like.

When it comes to charging times, the Xperia X, with its smaller juicer getting filled up some 15 minutes quicker than the larger unit of the Z5.

Battery life (hours) Higher is better
Sony Xperia X 8h 56 min (Good)
Sony Xperia Z5 7h 7 min (Average)
Charging time (minutes) Lower is better
Sony Xperia X 141
Sony Xperia Z5 156

Conclusion


Available for order at $549.99, the Xperia X is a smartphone that doesn't disappoint, but feels a bit too expensive for what it offers. And thanks to its seniority, the Xperia Z5 is dangerously close in terms of pricing—nowadays you can score one for as little as $600.

Taking these prices in mind, we're unable to recommend the Xperia X over the Z5. We like the way it feels in our hand better, sure, and its display is truly summer-proof, but in terms of camera and game performance, it's just not quite up there. The Z5 also comes with a great perk: water protection. A saving grace is the X's better battery life, but we didn't find that to be large enough of a lead to warrant a reconsideration on our part.

Our opinion? If you can get the Xperia Z5 for as much as $100 extra over the X, it's worth it. If you can't, go for the Xperia X
