The Samsung Galaxy S25 "Slim" is expected to launch in 2025 and is speculated to be between 6mm and 6.9mm thick, making it thinner than the current Galaxy S24 lineup.
This would be a significant decrease in thickness compared to the 7.6mm thick Galaxy S24 models.
While not as thin as the 5.9mm Galaxy A8 from 2015, the Galaxy S25 Slim is expected to be thinner than competitors like the Apple iPhone 16 and the Google Pixel 9.
It remains to be seen how much practical benefit the slim design will offer, but it is considered an impressive technical feat.
