During Samsung Unpacked 2025, we heard that the Galaxy S25 series phones have a "custom" (sort of) Qualcomm Snapdragon chip to power its features. That's pretty cool — we know Snapdragon chips perform well and we've seen what building an AI-tailored SoC allows in Google's Pixel phones.

The S25 Ultra is lighter at 218g compared to the 233g that the S24 Ultra weighs. In addition, the S25 Ultra has a more rounded, flat design when compared to the S24 Ultra. Samsung says that the S25 Ultra is 0.4 mm thinner than the Galaxy S24 Ultra.

Samsung Electronics has launched its new Galaxy S25 series, featuring Qualcomm chips and AI capabilities from Google's model. Despite competition, Samsung is focusing on enhancing AI features like Bixby and personalized experiences to boost sales.
