Rumors Suggest Thinner, Higher-Capacity Battery for Samsung Galaxy S26 Edge

Following the release of the Samsung Galaxy S25 Edge at the end of last year’s initial Galaxy Unpacked event – a launch that garnered significant attention despite its later relative quietness – speculation is now surfacing about substantial upgrades planned for the forthcoming Galaxy S26 Edge. The subsequent unveiling of the Galaxy Z Fold 7 and Galaxy Z Flip 7 in late July initially raised questions regarding Samsung’s continued focus on the Edge series. However, recent reports indicate a commitment to refining this flagship line.

A post shared by display name PhoneArt (formerly known as Ice Universe) on X on August 6th provided initial details: “Galaxy S26 Edge 5.5mm 4200mAh.” The “5.5mm” figure reportedly pertains to the device’s thickness, a notable reduction compared to the current Galaxy S25 Edge’s 5.8mm profile. This slimmer design would build upon the existing model’s impressive form factor.

The Galaxy S25 Edge currently utilizes a 3,900mAh battery; a size that reviewers have acknowledged as comparatively modest for contemporary flagship devices, albeit justifiable given the phone’s thinness. If the information shared by PhoneArt proves accurate, Samsung would achieve an approximate 8% increase in battery capacity while simultaneously reducing the device’s overall thickness.

Industry observers previously noted that the Galaxy S25 Edge’s design could potentially establish a new segment within the smartphone market. This latest rumor suggests Samsung is prioritizing this line and exploring further innovation. The potential for the Galaxy S26 Edge to emerge as a leading contender among both Samsung devices and Android phones generally, hinges on confirmation of these reported enhancements. While initial details remain limited, analysts advise awaiting additional reports before drawing definitive conclusions.
