Samsung may have discovered a new path of innovation for its smartphones. The company is gearing up to launch its slimmest smartphone next week, the Galaxy S25 Edge, and it could just be the beginning. The goal is to continue making phones slimmer without compromising their functionality or features. Industry insiders suggest the Galaxy S26 series next year could be thinner than the S25 lineup.
Samsung’s slim future: Galaxy S26 to push even thinner design boundaries
Measuring just 5.84mm thick, the Galaxy S25 Edge is an incredibly thin smartphone, the slimmest Samsung has ever made. It will follow up with an ultra-thin Galaxy Z Fold 7 in a couple of months. The next foldable is expected to measure 3.9mm when unfolded and 8.9mm when folded, more than 3mm thinner than the Fold 6 (12.1mm).
According to reliable insider Ice Universe, these devices are indicative of Samsung’s design direction for its future products. The Galaxy S26 series will continue to focus on thinner and lighter builds. Of course, Samsung may not move beyond a thickness of 5.8mm — the S25 Edge is a special model — but expect it to make the 2026 flagship slimmer than the S25 lineup.
To recall, this year’s flagships are already slimmer than the 2024 models. But Samsung doesn’t want to stop there. It is exploring new battery technologies, as well as other design advancements, to slim down its phones. The company may use silicon-carbon battery technology to make thinner batteries, without reducing the capacity.
Unfortunately, the Galaxy Z Fold 7 misses out on battery advancements. A slim body means Samsung couldn’t make the battery bigger, which is a major concern. Hopefully, the company has figured out how it plans to go about these problems in the future. Expect more details about the Galaxy S26 series to emerge in the coming months.
