Call quality

The earpiece of the Xperia X does a good job, transmitting fairly clear (if slightly hissy) voices and offering satisfactory volume. The mic, on the other hand, is a bit subdued.

The iPhone has never been known to be the best of the best when it comes to call quality, but for the most part, it does well in handling conversations, with acceptable performance through its earpiece. Voices come in a relatively natural and dynamic way, so we don't have complaints in this regard. The microphone does a similarly good job at transferring our voice to our callers, with a mostly clean and defined sound quality.


Sony touts two-day battery again, and with nearly 9 hours screen-on time in our test, the Xperia X is bound to deliver.

Partnering with Qnovo to offer supposedly superior adaptive charging that will allow the 2,620 mAh battery inside the Xperia X to last and stay healthy for longer, Sony claims up to two days of battery life, as usual with its Android phones lately, and while two-day battery life may indeed be possible with a more conservative usage scenario, we think going for a day and a half seems more realistic. On our test, the Xperia X

scored 8 hours and 46 minutes of screen-on time. The iPhone 6s' 1715 mAh pack, on the other hand, managed to last 8 hours and 15 minutes on our test, and it also took a bit longer (150 minutes vs 140 minutes) to be recharged. Overall, both handsets tend to deliver comparable amounts of juice before calling it quits, though your mileage may vary depending on your usage type.

Battery life (hours) Higher is better
Sony Xperia X 8h 56 min (Good)
Apple iPhone 6s 8h 15 min (Average)
Charging time (minutes) Lower is better
Sony Xperia X 141
Apple iPhone 6s 150


With its more elegant body, better camera, faster chipset, and record LTE band support, the iPhone 6s seems destined to remain the popular choice compared to the Xperia X. Moreover, Sony priced its midranger just a hundred lower than the iPhone 6s, which wouldn't help its cause at all.

The Xperia X is a decent phone with a stylish appearance. However, the iPhone 6s is a superb phone that's also stylish. And with the current pricing schemes employed by the two manufacturers, there really doesn't seem to be that much actual competition going on here. Apple's proposition comes across as the much better one, all things considered.
