TL;DRA new Samsung battery listing hints that another foldable device could be in the works.Samsung’s 2026 foldable lineup is already expected to include the Z Fold 8, Z Flip 8, and a Wide Fold, but this listing doesn’t match those devices.The listed battery capacity matches a rumored Z Fold 8 cell, suggesting a variant like a Z Fold 8 FE is the most plausible possibility.Samsung’s foldable plans for 2026 already looked pretty stacked. Between the expected Galaxy Z Fold 8, Galaxy Z Flip 8, and the much-rumored Wide Fold, it seemed like the company had its big flexible-screen plays covered for the year. But a fresh certification clue suggests Samsung may still have room for one more foldable surprise. As SammyGuru reports, a new battery listing on China’s 3C certification database points to a Samsung device with the model number SM-F977. That stands out because Samsung’s recent Fold-series model numbers generally sit in the F9xx range, while the regular Galaxy Z Fold 8 has already been linked to SM-F976 and the rumored Wide Fold to SM-F971 in earlier leaks.
