Samsung Galaxy S26 Ultra's battery capacity confirmed amid design doubts

The Samsung Galaxy S26 Edge is expected to feature a thinner design and a larger battery, potentially up to 4,200mAh, though recent leaks suggest it may not be as slim as previously rumored. The device is also associated with high-end Qualcomm processors and may use traditional lithium-ion batteries instead of silicon-carbon technology, indicating possible changes in its design and capacity. Despite uncertainties, it may still offer better endurance than the iPhone 17 Air.
