Samsung is reportedly developing a Galaxy tri-fold phone, potentially incorporating a silicon-carbon battery. Leaks suggest the company aims for a slim design, with the new battery technology contributing to reduced thickness.
Moreover, the phone is rumored to be launched in the second half of 2025, following hints at Samsung’s tri-fold ambitions earlier this year.
Samsung Galaxy Tri-Fold Silicon-Carbon Battery Rumors
This silicon-carbon battery could be Samsung’s first, possibly preceding its adoption in the S26 series. While battery capacity is expected to remain around 5,500mAh for the S26 Ultra, the new technology promises higher energy density, storing more power in less space.
However, the tri-fold’s battery might be under 5,000mAh to prioritize thinness. This contrasts with Chinese manufacturers like vivo and Xiaomi, who are offering larger 6,500 to 7,000mAh batteries. Samsung seems to be focusing on matching the Z Fold 6’s 4,400mAh capacity while reducing size.
The final design remains uncertain, as the leak is based on a prototype. Samsung faces competition from Huawei’s Mate XT tri-fold, particularly in China. The company’s challenge is balancing thinness, durability, and battery life in this new device, potentially launching in July 2025 alongside the Z Fold 7.
