We don't have Sony Xperia 4 pictures yet, so here's one of the Xperia 10
Sony is trying to simplify the branding of the company's long-struggling smartphone portfolio, dropping the somewhat confusing letters following the Xperia moniker and starting over with new digits. The Xperia 1 is the latest flagship device, formally unveiled at the MWC 2019 trade show a couple of weeks ago alongside the "super mid-range" Xperia 10 and 10 Plus.
starting at $350 with Snapdragon 630 processing power in tow, there's still a bit of a gap left between these "super mid-rangers" and the high-end Xperia 1. According to some fresh speculation, a 5.7-inch Sony Xperia 4 could come soon to occupy that space, packing a Snapdragon 710 SoC.But even though the Sony Xperia 10 duo provides decent bang for your buck,
As the name suggests, that's a significantly speedier chipset than the Snapdragon 636 found under the hood of the Xperia 10 Plus. It's the same processor used on upper mid-end devices like the Nokia 8.1 and Samsung Galaxy A9 Pro (2019), while Google is also expected to integrate it into at least one Pixel 3 Lite variant. Basically, that makes this a "lite" version of the Sony Xperia 1, with 4 instead of 6GB RAM and a mysterious dual camera setup also on deck to downgrade the triple lens solution of the company's new hero phone.
The Sony Xperia 4 could be a compact version of the Xperia 1 as well, although at 5.7 inches, it would be quite a stretch to call it a sequel for the 5-inch Xperia XZ2 Compact. Coincidentally, the Xperia 4 and XZ2 Compact are tipped to share the same 65 mm overall width, but the former should stand considerably taller, at 149.5 mm. The Xperia 4 could be thinner than the XZ2 Compact, but thicker than the Xperia 10, at 9.4 mm.
Unfortunately, the battery size might actually be downgraded from the 2,870 mAh on the Xperia 10 to 2,800 mAh. With a smaller screen rocking the same unusual 21:9 aspect ratio and decent 2520 x 1080 resolution, that would probably result in similar endurance numbers, but Sony could surely do better in terms of the battery capacity of a 9.4 mm thick phone.
Other rumored features include a combination of 4GB RAM and 64GB internal storage space, which is a pretty good mid-range setup, but alas, no headphone jack, just like on the Sony Xperia 1. For what it's worth, the Sony Xperia 4 is expected to launch sometime this summer in a nice quartet of paint jobs, including silver and black, as well as snazzy red and purple flavors.
