Samsung may finally address one of the longest-running criticisms of its foldable lineup with the upcoming Galaxy Z Fold8, which is rumored to feature a larger battery than its predecessors.
The Galaxy Z Fold series has retained a 4,400 mAh battery since the launch of the Galaxy Z Fold3, despite rising screen sizes and performance demands. Notably, the earlier Galaxy Z Fold2 actually offered a larger 4,500 mAh battery.
Modest but meaningful increase expected
According to a new report, Samsung plans to increase battery capacity with the Galaxy Z Fold8, which is expected to debut later this year. The device is said to feature a 5,000 mAh battery, bringing it in line with the company’s flagship bar-style phone, the Galaxy S26 Ultra.
While a 5,000 mAh battery would still lag behind some rival foldables, it would represent a nearly 14% increase over recent Fold models and mark the first capacity upgrade in the lineup since 2021.
Dual-battery design to remain
The Galaxy Z Fold8 is expected to continue using a dual-battery configuration, with one battery placed on each side of the foldable frame. The two cells are reportedly rated at 2,369 mAh and 2,485 mAh, for a combined rated capacity of 4,854 mAh, which Samsung would market as a typical 5,000 mAh battery.
Wider Fold model also rumored
The report also references a separate “wide Fold” model that Samsung may introduce alongside the Fold8. This variant is said to feature a 4,900 mAh battery and a wider form factor, positioning it as a potential competitor to Apple’s rumored foldable device, often referred to as the iPhone Fold.
Expected launch timeline
Both the Galaxy Z Fold8 and the wider Fold model are expected to be unveiled around July, in line with Samsung’s typical summer schedule for foldable phone launches.
If the reports prove accurate, the battery upgrade could signal a shift in Samsung’s foldable strategy, addressing a key user concern while keeping the overall design evolution conservative.
