Recent leaks indicate that the Galaxy Z Fold8 (previously referred to as the Galaxy Z Fold Wide) and the Galaxy Z Fold8 Ultra—the successor to the Galaxy Z Fold7—will feature significantly larger batteries compared to their predecessors. Rumors suggest that Samsung is adopting innovative Si/C battery technology, leading many to wonder about the improvements in battery life.
To accurately assess the battery performance, we will need to conduct tests upon receiving our review units. However, insights from EU regulatory bodies provide a preliminary indication of what to expect regarding endurance.
The European Product Registry for Energy Labeling (EPREL) has published the endurance ratings for the Galaxy Z Fold8 and Galaxy Z Fold8 Ultra, listing 49:10 hours and 51:00 hours, respectively. Both devices utilize 4,800 mAh and 5,000 mAh batteries.
Comparing the Galaxy Z Fold8 Ultra to its predecessor, the Galaxy Z Fold7, which had a 40:28 hour rating and a 4,400 mAh battery, reveals an approximate 20% increase in endurance.
It is important to note that individual experiences may vary based on personal usage patterns. Nevertheless, it is clear that the Galaxy Z Fold8 series will benefit from larger battery capacities—a much-needed upgrade in performance.
