S25 Edge: Samsung’s thinnest phone packs powerful AI features

Samsung Electronics (005930.KS), opens new tab made public on Tuesday its slimmest flagship model to date, complete with enhanced artificial intelligence features, as it seeks to get ahead of rival Apple (AAPL.O), opens new tab in the premium market.

The S25 Edge launch is designed to tap increasing demand, especially from consumers in their 20s and 30s, for more portable smartphones.

"The feedback was clear – users wanted something slimmer and easier to carry without sacrificing performance," said Samsung, which made structural changes to reduce the thickness of internal components, including the printed circuit board and thermal systems.

Analysts said the launch was strategically timed to pre-empt Apple, which is expected to launch a thinner iPhone in the second half of this year.

"By releasing the product a few months ahead, Samsung could inflict some impact on Apple and attract consumers looking for thinner smartphones. It appears to be a calculated decision to capture that segment of demand," Ryu Young-ho, a senior analyst at NH Investment & Securities, said.

The S25 Edge will go on sale in South Korea on May 23 and in the United States on May 30, Samsung said, adding it will roll it out to about 30 countries, including China and in Europe.

Starting at $1,099, the model has a 6.7-inch (170 mm) screen and a 5.8 millimetre-thick body, making it larger than the basic S25 model but only fractionally heavier.

The S25 Edge has Samsung's latest built-in AI functions, including multimodal AI that allows users to interact with the device in real time through vision and voice, using the camera to ask questions.

Samsung did not disclose the production site for the new model.

At the launch event, Samsung dismissed concerns about potential performance and heat management issues with the device.

 "Some may worry that a thinner phone compromises performance or struggles with heat management," said Samsung Electronics Executive Vice President Moon Sung-hoon.

"We managed to engineer a thinner vapor chamber to fit the slim design, and we put everything into making that happen. We’re confident the S25 Edge can be used without concerns about overheating," said Moon.

Samsung became the world’s leading smartphone vendor in the first quarter of 2025, capturing 20% of the global market and narrowly surpassing Apple, which held a 19% share, data from Counterpoint Research showed.
