Samsung has gradually increased the battery capacity in its clamshell foldables over the past few generations. But that trend may pause with the upcoming Galaxy Z Flip 8, according to a new leak.
A report from GalaxyClub suggests the next Flip will keep the same 4,300 mAh typical battery capacity found in the Galaxy Z Flip 7. That would mark the first time in a while that Samsung hasn’t bumped the battery size for its compact foldable.
Like previous Galaxy Z Flip models, the device is expected to rely on two separate battery cells working together. The leaked figures point to capacities of 1,150 mAh and 3,024 mAh, which combine for a rated capacity of 4,174 mAh. Samsung typically rounds this up to the advertised 4,300 mAh typical capacity.
Even though the overall capacity appears unchanged, the split between the two cells is slightly different from last year’s model. That could simply be the result of internal design changes as Samsung continues refining the Flip’s slim folding body.
Battery capacity staying the same doesn’t necessarily mean endurance will remain unchanged, however. The Galaxy Z Flip 8 is rumored to feature Samsung’s 2nm-based Exynos 2600 chipset, which could offer a significant boost in power efficiency over the 3nm-based Exynos 2500 used in the Z Flip 7. Early tests also suggest the Exynos 2600 offers better thermal behavior under heavier workloads such as gaming or multitasking.
Samsung is expected to unveil the Galaxy Z Flip 8 sometime in July 2026, likely during its usual summer Galaxy Unpacked event. The phone should launch alongside the Galaxy Z Fold 8, continuing the company’s yearly foldable refresh cycle.
Pricing details remain unclear for now, though Samsung has generally tried to keep its Flip lineup relatively stable in price.
For now, the leaked battery information suggests the Flip 8 may focus more on efficiency and internal refinements rather than a straightforward capacity upgrade. Whether that translates into noticeably better battery life will depend largely on how Samsung balances the Exynos 2600’s performance and power consumption.
