We’ve heard similar claims earlier, but now, we have some concrete numbers at our disposal. The latest leak reads that the three flagship models will allegedly shed some fractions of the millimeter. The goal is to come closer to Galaxy S25 Edge, the first super-thin Galaxy S phone.
So, here are the numbers:
Expected thickness | Expected reduction | Predecessor thickness | |
---|---|---|---|
Galaxy S26 Pro | 6.7 mm | 0.5 mm | 7.2 mm (Galaxy S25) |
Galaxy S26 Edge | 5.5 mm | 0.3 mm | 5.8 mm (Galaxy S25 Edge) |
Galaxy S26 Ultra | 7.8 mm | 0.4 mm | 8.2 mm (Galaxy S25 Ultra) |
What’s even more impressive is that the slimmest of them all – the Galaxy S26 Edge model – will highly likely pack a 4,300 mAh battery, as we told you recently. The S25 Edge had a 3,900 mAh capacity battery on board.

As far as the eventual S26 Ultra goes, the report states this is how slim an Ultra model can get with the current built-in S Pen. So, if future S Ultra phones want to go below 7.8 mm, they’ll probably have to rely on an external S Pen, or a stylus that’s much slimmer than the one we have now. Or maybe drop the S Pen totally?
Well, it happens so that the Galaxy S26 Pro moniker might be used for the Galaxy S26, simple as that.
Samsung’s Galaxy S series has long stuck to a three-model formula – standard, Plus, and Ultra – but the Galaxy S26 lineup may break tradition.
A GSMA database entry listing the S26 Pro under model number SM-S942, previously linked to the base S26, hints at a simple renaming rather than major hardware changes. The “Pro” label seems aimed at aligning Samsung’s strategy with Apple and Chinese rivals, potentially justifying a price increase without substantial upgrades.
Also, the Plus model could be replaced by the Edge variant.
Regardless of the monikers, though, the Galaxy S26 models might all be thinner. Yay or nay?
