Sony Xperia Z5 Compact key test findings
The Xperia Z5 Compact has superb build-quality. The exposed microUSB port is a lot more convenient than Sony's previous covered solution, but the volume keys is somewhat oddly positioned.
The display offers superb maximum levels of brightness and pretty good contrast. The resolution is still only 720p, same as last year's generation.
The side-mounted fingerprint reader is really convenient, fast and reliable.
Battery life is solid with a really respectable 86 hours of endurance rating. However it falls short of the 101 hour rating the Z3 Compact got in our test.
Based on Android 5.0, the Xperia launcher runs quite nicely on the Z5 Compact and is packed with several interesting features. The phone is definitely not lacking on the software side.
Performance-wise, the Xperia Z5 Compact is a true powerhouse, equipped with Qualcomm's top-of-the-line Snapdragon 810 SoC. The low screen resolution combined with the high-end GPU enables one of the most impressive OpenGL ES 3.1 frame rates we have seen.
The speaker setup on the Z5 Compact is only average in terms of loudness, but this is actually ok for a device with stereo speakers.
The camera setup on the Z5 Compact offers accurate colors and good dynamic range, but sadly samples were still plagued by typical Sony problems - poor edge to edge sharpness and a lot of low-light noise.
