The Xperia 10 IV is not even that different from its predecessor; the Xperia 10 III. For example, there's still a 6-inch OLED screen with an elongated 21:9 ratio. And the triple camera (12+8+8MP) has also remained the same on paper.

The battery is different; its capacity increased from 4500 to 5000 mAh. Remarkable is this does not increase the weight. On the contrary, it even decreases, making the Xperia 10 Mark 4 a lightweight phone of just 161 grammes.
Triple camera
The camera system of the Sony Xperia 10 IV consists of three cameras as mentioned above; a 12MP primary camera with a 27mm wide-angle lens, an 8MP ultra-wide-angle (16mm), and an 8MP telephoto camera for 54mm zoom. These provide Sony with various features, including filters, backlight correction, and a nite portrait mode. In addition, optical image stabilisation is added to shoot sharp pictures even in dark situations.

Prices and availability
The Xperia 10 IV has a suggested retail price of €499. That's higher than its predecessor. Expect the device in stores from summer in the colours black or white.
