Battery life

When it comes to battery life, the Xperia X sports a 2,620 mAh unit, while the Galaxy S7 has a much larger, 3,000 mAh cell.

Daily usage so far shows that it is roughly in the same league as the S7, lasting maybe just a bit less in our prolonged usage. Sony claims you can get two-day battery life with the X, but we found this claim far-fetched, at least in our experience.

Then, there is recharge times. Sometimes you just have a few minutes or half an hour to juice up, and in those cases the Galaxy S7 is definitely the better one: it takes less than an hour and a half to fully recharge the S7 from 0% to 100%, while the Xperia X takes an excruciatingly long 2 hours and 20 minutes to juice up, despite having a smaller battery capacity.

At the end of the day, the Sony Xperia X turns out to be a good phone with a beautiful and refined design, while performance is decent in practically every department, but never great. The phone is priced at $550, upper mid-range territory and $150 less than the Galaxy S7, which typically retails for around $700.

The Xperia X feels a bit pricey, especially in this fiercely competitive market. Its display might look good to lay-men, but upon closer inspection, you’d notice that it's a bit bluish and colors are not well-balanced; its Snapdragon 650 is a noticeable step below the Snapdragon 820, which will be noticed for those who edit pictures, browse the web a lot, and play games on their phones. And then, the image quality and camera experience is a bit below expectations. It also lacks catchy new features that the Galaxy S7 has aplenty in the form of Motion Photo, Always-on Display, Game Center, and so on.

In a direct comparison, regardless of price, we’d pick the Galaxy S7 without hesitation: it’s faster, has a mind-bogglingly speedy camera, as well as waterproofing and wireless charging – two very nice extras. While a bit overpriced, the Xperia X will still appeal to lovers of great design and the Sony brand name, but looking at the bigger picture, it underdelivers.
