The Xperia X Performance’s 5-inch 1080p IPS LCD display is also somewhat disappointing. It’s over-saturated, but not in a good way like Samsung’s Super AMOLED technology. Bright colors appear slightly blown out, which is especially noticeable in apps that follow Android’s Material Design guidelines. But if nothing else, the X Performance’s display can get very bright, which is nice when you need to use the phone in glaring summer sunlight.
Performance: Yep, it’s the 820
Unlike the Xperia X, which uses the mid-range Snapdragon 650 processor, the Xperia X Performance uses Qualcomm’s latest high-end chip, the Snapdragon 820. It’s the same chip that’s inside all of its competitors, including the Galaxy S7, HTC 10, and LG G5.
Sony’s Xperia X Performance tested rather well in day-to-day tasks like browsing the web and switching between apps.
Like to play games? The Xperia X Performance is capable, but the Galaxy S7 beat it slightly in 3DMark.
The Xperia X Performance performed as expected alongside the rest of the flagship lineup in our benchmark tests. In PCMark, which tests pedestrian tasks like browsing the web and editing documents, the phone actually performed better than the competition, despite boasting the same 3GB of RAM included in all the other phones. However, 3DMark results came in short of the competition, despite Sony using the same chip. Regardless, no app stuttered during my own day-to-day testing.
The Xperia X Performance’s battery life was incredibly disappointing.
The Xperia X Performance’s battery results were disappointing—especially considering this higher-end model has a slightly larger battery than the mid-range Xperia X.
In our Geekbench battery rundown test, the phone’s 2700mAh battery died nearly two hours earlier than the Galaxy S7’s slightly larger 3000mAh battery. Even the Xperia X, which uses an incrementally smaller 2620mAh battery, outlasted the so-called “Performance” model. The Xperia X Performance fared just a bad in PCMark's battery test. The results were a bit surprising considering the stellar battery life I experienced with the device on standby.
An OK camera for an OK phone
The Xperia X Performance’s 23-megapixel camera pairs better with the device’s Snapdragon 820 processor.
Like the mid-range Xperia X, the Xperia X Performance features a 23-megapixel rear-facing camera with an aperture of f/2.0. Lke its sibling, the phone shoots with 8-megapixels on the rear by default, so you’ll have to go in and change that before you start snapping away. There’s also a 13-megapixel front-facing camera.
