Samsung looks set to continue its obsession with slimmer smartphones in 2026. Following the sleek Galaxy S25 Edge and the trimmed-down Galaxy Z Fold 7, new leaks suggest that every Galaxy S26 model will sport a thinner frame than its predecessors.
This doesn’t mean all versions will match the extreme thinness of the S25 Edge, but users can expect a more streamlined design with an improved grip.
The challenge for Samsung will be balancing slimmer profiles with larger batteries. Reports indicate the company aims to equip the Galaxy S26, S26 Edge, and S26 Ultra with higher-capacity cells
. Well-known leaker Ice Universe has already claimed the S26 Ultra will be thinner and lighter, though conflicting rumors raise doubts about its final battery size.
One possible solution lies in silicon-carbon battery technology, rumored to boost capacities up to 7,000mAh without expanding the phone’s footprint. Still, Samsung is said to be undecided on its lineup strategy. Some leaks hint at the Galaxy S26 Pro replacing the base model, while the Galaxy S25 Edge could take the place of the Plus version. However, the company has reportedly not finalized whether the Plus variant will remain in the family.
What’s clear is that Samsung intends to shake up its flagship series once again. With thinner builds, potential battery breakthroughs, and a possible reshuffle of the model lineup, the Galaxy S26 family is shaping up to be one of the most intriguing releases yet.
