Sony Xperia X Performance Review
Ranked in these QuestionsQuestion Ranking
Pro Great UI
Traditionally, Sony keeps design elements familiar to stock Android, and it really looks good. They do add their own features - mini apps (which replicate dual-window functionality), as well as different battery saving modes for different levels of urgency to save power. Based on early hands on impressions, it looks like the Xperia X Performance follows with the ideology originally created with the Xperia Z lineup.
Pro High end specs
Although full reviews aren't out yet (and won't be for some time), on paper the Xperia X Performance packs a lot for it's somewhat compact design. A 23MP camera, Snapdragon 820 processor, 3GB of RAM, 1080p display, and two front facing stereo speakers...looks like a powerful overall package.
The Sony Xperia X Performance doesn't offer much over the competition - it has actually taken a step back by removing waterproofing and using a smaller battery. The design is unique, but dated. Sony hasn't had a major design since 2012.
Con Not available yet
Sony hasn't given a date when you can actually buy the X Performance, but sources say to expect early in the summer. It's a ways away, but it has been officially launched
