SamMobile first reported a 245mAh battery in March 2026, describing it as Samsung's first smart glasses. 9to5Google later reported 155mAh specifically for the display-free 2026 model, and suggested the 245mAh number might belong to the display-equipped 2027 model instead, though no source has confirmed that reassignment. Samsung has released no runtime figures. For comparison, Meta Ray-Ban Gen 1 used a 154mAh battery; Meta hasn't disclosed a Gen 2 figure.
Two sources, one number conflict. 9to5Google and Tom's Guide both cite 155mAh for the Galaxy Glasses battery, so that part's consistent, but 245mAh is still floating around elsewhere. A 155mAh cell is tiny, roughly a third of what's in a typical wireless earbud case, so the higher figure would change how long these last between charges.
