Sony Xperia 4 could come with upper mid-range SoC, tall screen, no headphone jack
We don't have Sony Xperia 4 pictures yet, so here's one of the Xperia 10
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.
