Sony Xperia 1 IV

The predecessor to the current top model also offers a powerful camera.

Making phone calls, sending messages, surfing the internet - for most people, everyday life is hardly conceivable without a smartphone. It is therefore all the more important to be able to rely on the devices. The Stiftung Warentest smartphone test answers the question of which model is the test winner and which ones lack stability or basic functions.

Although the Xperia 10 IV costs just over a third of Sony's top model, the devices share a lot of advantages (IP68, eSIM, expandable memory, jack socket) and one shortcoming: the too-short updates. Beyond that, both devices have their own strengths. The cheaper 10 IV runs for an extremely long time and even breaks a runtime record on the c't test bench - the 1 IV can't keep up with it by far...

Both the main camera and the super-wide-angle module leave a positive impression in the test. In the JPEG setting, they come close to the rating "very good". In RAW format, both improve in terms of fine detail, but also have more noise. Although no QUAD technology is used, Sony relies instead on large 12 megapixel sensors...
