Samsung's new foldables lose 800 rated battery cycles versus their predecessors

European energy labels list 1,200 full charge cycles for Samsung's new foldables, down from 2,000 for the previous generation.

Samsung's new foldable smartphones unexpectedly come with a lower rated battery lifespan than the previous generation. According to European energy labels, the batteries in the Galaxy Z Flip 8, Galaxy Z Fold 8 and Galaxy Z Fold 8 Ultra are rated for at least 1,200 full charge cycles, after which available capacity may fall to 80% of the original level.

By comparison, the specifications for the Galaxy Z Flip 7 and Galaxy Z Fold 7 list at least 2,000 cycles. That is an 800-cycle gap in favor of the older models. Actual degradation will still depend on temperature, charging habits and operating conditions.

The Galaxy Z Flip 8 has a 4,300 mAh battery, so at the 80% threshold its estimated available capacity would be about 3,440 mAh. The Galaxy Z Fold 8 would retain roughly 3,840 mAh from its 4,800 mAh battery, while the Galaxy Z Fold 8 Ultra would have around 4,000 mAh left from 5,000 mAh.

The lower cycle rating coincides with Samsung's switch to silicon-carbon batteries in its new foldables. The technology makes it possible to fit more capacity into a thinner body. However, EPREL data does not explain the shorter rating and does not prove that battery chemistry is the decisive factor.

Even after the reduction, a 1,200-cycle rating remains comparable with a number of modern smartphones. Samsung has not officially explained the gap between generations, so it is unclear whether it comes from cell design, certification methods or a different durability margin.
