TL;DR A Korean outlet has claimed that the Galaxy Z Fold 8 could have a battery larger than 5,000mAh.
This would be a dramatic and overdue increase in battery capacity for the Z Fold family.
The phone is also tipped to offer S Pen support and a reduced display crease.
The Samsung Galaxy Z Fold 7 is one of the best foldable phones of 2025, and that’s largely due to its cutting-edge design. However, the Z Fold 7 retains a 4,400mAh battery for the fifth straight generation, while Samsung also nixed S Pen support. There might be good news for the Galaxy Z Fold 8, though.
Dealsite (via Jukanlosreve on Twitter) reports that the Galaxy Z Fold 8 could have a battery larger than 5,000mAh. This would be much bigger than the Z Fold 7’s 4,400mAh battery.

Such a dramatic increase in battery capacity would be very uncharacteristic of Samsung. In addition to every Z Fold model since the Z Fold 3 offering the same 4,400mAh battery capacity, the firm’s Ultra phones have stuck with 5,000mAh batteries since 2021. We have seen a couple of notable battery upgrades in 2025, though, namely the Galaxy Z Flip 7 (4,000mAh to 4,300mAh) and Galaxy S25 FE (4,500mAh to 4,900mAh). Either way, I wouldn’t hold my breath for a massive battery upgrade, but I hope to be proven wrong.
Otherwise, the outlet says there are “high expectations” that the new foldable phone will support the S Pen after Samsung skipped this feature on the Z Fold 7. Samsung claimed at the time that it removed the digitizer layer that enables S Pen input to deliver the Fold 7’s ultra-thin design.
