Samsung's forthcoming Galaxy S26 Edge model may boast a slimmer design, yet reportedly maintains sufficient space for a larger battery.
The Samsung Galaxy S26 Edge is shaping up to be a significant milestone in the Galaxy S series, with rumors suggesting a new chapter in the series' story. This next-gen device is expected to boast a thinner design, along with a modestly increased battery capacity, marking a notable engineering achievement.
According to reports, the Galaxy S26 Edge is set to sport a battery capacity of approximately 4,200–4,400 mAh, a 300mAh increase over its predecessor, the Galaxy S25 Edge. Simultaneously, the phone is rumored to be 3mm thinner, measuring just 5.5mm.
To achieve this engineering balance between battery life, device thinness, and internal component optimization, Samsung is employing several design and technological innovations. These include adopting silicon battery technology, redesigning compact internal components, and using slimmer vapor chamber cooling systems and thinner protective glass on the front and rear panels.
The adoption of silicon battery technology allows for higher energy density in a thinner form factor, enabling the battery to increase capacity without adding thickness. A redesigned camera module using a “ring pattern” of printed matte ink helps save space and reduce the camera bump, while more compact internal components contribute to the overall device slimming.
Samsung's use of slimmer vapor chamber cooling systems and thinner protective glass on the front and rear panels further contributes to slimming the device without sacrificing battery or performance. Together, these innovations allow Samsung to increase the S26 Edge’s battery capacity by approximately 300 to 500mAh while making the phone about 0.3 mm slimmer.
It remains uncertain how Samsung will fit a bigger battery into a smaller phone, but the rumored battery upgrade indicates that the new design might not compromise on features. The focus on aesthetics is also evident, with the Galaxy S26 Edge expected to be thinner than its predecessor.
Interestingly, rumors suggest that Samsung will not release the Galaxy S26 Plus, with the S26 Edge expected to be the main focus of the upcoming release. For the latest news and rumors about the next Samsung flagship, follow the Samsung Galaxy S26 hub.
