Samsung is reportedly on the verge of significant advancements in smartphone battery technology. The company is experimenting with exceptionally large batteries for its upcoming Galaxy devices.
Sources indicate that Samsung is developing several battery prototypes, including a 12,000mAh and an 18,000mAh option, while a more ambitious 20,000mAh battery was sidelined after it fell short during testing at just 960 charging cycles. Predictions hinted at the possibility of 6,000mAh to 7,000mAh batteries for phones expected in 2026, but the Galaxy S26 Ultra remains equipped with a 5,000mAh battery.
Documents reveal that the firm is focusing on battery size and longevity as key parameters for its upcoming models. Tests are said to explore whether a 12,000mAh silicon-carbon battery can be effectively integrated into future Galaxy devices. One proposed configuration involves a “dual stacked cell” design, joining a 6,800mAh cell with a 5,200mAh counterpart, resulting in a total stack thickness of approximately 9mm. This battery may endure up to 1,500 charging cycles before it retains only 80% of its original capacity.
Additionally, the exploration of an 18,000mAh battery with a “tri-cell vertical stack” structure is underway, combining three cells of 6,699mAh, 6,000mAh, and 5,257mAh. If this moves forward, the total thickness could reach 12.3mm, which may clash with Samsung’s design ethos favoring slim devices. Another prototype, a massive 20,000mAh battery, reportedly failed in trials.
The overall sentiment remains that Samsung has been preoccupied with creating sleek designs and integrating AI features, potentially sidelining battery technology. Users express frustration over the frequency of charging and the need for increased longevity in their devices. While the Galaxy line has seen advancements, battery performance continues to be an area where fans hope for more notable improvements.
