There are two new members of Sony’s Xperia X line of smartphones. The new Xperia XZ is a 5.2 inch phone that could be the company’s new flagship, thanks to slightly beefier specs than you get from the Sony Xperia X Performance.
Meanwhile, the Sony Xperia X Compact is a 4.6 inch phone for folks lamenting the fact that it’s hard to find a good smartphone smaller than 5 inches.Sony has released “compact” editions of its last few smartphones, usually with specs that are similar to those for its high-end flagship phones. This time things are little different.
Typically Sony’s smaller phones have a lower-resolution display and a smaller battery than their bigger counterparts, but the same processor.

This year things are a bit different, because larger Xperia X phones come with a range of processors. The Xperia X Performance and Xperia XZ are powered by Snapdragon 820 processors. The Xperia XAÂ has a MediaTek Helio P10. And the Xperia X has a Snapdragon 650.
So the latest Compact phone has the same processor as one of Sony’s larger phones. It just happens to be the mid-range version.

That said, the Xperia X Compact does have the same 3GB of RAM and 23MP rear camera you’ll find on the larger phones. And while the Xperia XZ has a 2,900 mAh battery, the Compact edition has a 2,700 mAh battery — which should provide similar battery life, given all the other differences between these phones.
Sony says the Xperia X Compact will be available globally in September, with the Xperia XZ coming in October.
