Samsung Says Z Fold 8 Meets 1,200-Cycle EPREL Standard, Not a Battery Downgrade

Summary
Samsung said the Galaxy Z Fold 8, Z Fold 8 Ultra and Z Flip 8’s 1,200-cycle rating reflects compliance with the EU’s EPREL standard, countering reports that the new foldables suffered a battery-life downgrade.
The company said earlier 2,000-cycle figures on devices like the Z Fold 7 used Samsung’s own testing method, while EPREL applies a standardized measure of battery health and longevity across phones.
Under that standard, the new foldables can lose up to 20% capacity after 1,200 charge cycles, yet still compare favorably with rivals such as Google’s Pixel 10 Pro and Apple’s iPhone 17 Pro at 1,000 cycles.
Battery capacity also increased in the new lineup, with the Z Fold 8 at 4,800mAh and the Z Fold 8 Ultra at 5,000mAh, suggesting daylong use should remain feasible even as batteries age.
The clarification reverses earlier assumptions that Samsung’s first partial silicon-carbon batteries traded lifespan for capacity, reframing the issue as a certification change rather than a hardware setback.
