Samsung appears poised to significantly upgrade the charging capabilities of its next-generation foldable smartphone, the Galaxy Z Fold 8. This potential shift represents a notable change for the Z Fold series, which hasn’t seen a major update to its charging technology since 2020. The move comes as consumers increasingly demand faster charging speeds, and Samsung appears to be responding.
Leaks originating from China’s 3C certification agency reveal that the upcoming Galaxy Z Fold 8, internally designated SM-F9760, is expected to move beyond the current 25W wired charging standard to a faster 45W charging speed. This would be a substantial improvement for Samsung’s foldable line, which has remained relatively conservative in adopting faster charging technologies despite user requests. The upgrade places the Z Fold 8 in line with other premium devices on the market.
Faster Charging, Larger Battery for the Z Fold 8
If confirmed, this would mark the first time in six years that Samsung has increased the charging speed of its book-style foldable smartphone. Currently, the Galaxy Z Fold series has been limited to 25W charging since its inception. However, Samsung has begun to show a willingness to embrace faster charging on other devices, including the Galaxy Z Trifold, which also supports 45W charging. This trend extends to the Galaxy S series as well, with the Galaxy S26 Ultra expected to feature 60W wired charging this year, according to recent reports.
This increase in charging speed isn’t expected to be the only improvement for the Z Fold 8. Rumors suggest the device will also boast a larger battery capacity, potentially reaching 5000 mAh – an increase from the 4400 mAh battery found in the Galaxy Z Fold 7. This larger capacity will be split across two cells, with capacities of 2,369 mAh and 2,485 mAh. Despite the increased battery size, the faster charging speed is anticipated to significantly reduce charging times. Currently, a full charge of the Galaxy Z Fold 7 takes approximately 90 minutes.
Samsung Expanding Charging Capabilities Across its Foldable Lineup
The potential 45W charging upgrade for the Galaxy Z Fold 8 aligns with a broader trend of Samsung increasing charging speeds across its product lines. Reports indicate that the Galaxy Z Fold 8 and a potential “Wide Fold” device will both support 45W charging, while the upcoming Galaxy Z Flip 8 will reportedly remain at a slower charging speed.
Samsung is expected to launch the Galaxy Z Fold 8 in July, maintaining its traditional release schedule. The combination of a larger battery and faster charging capabilities could address a key criticism of previous Z Fold models and further solidify Samsung’s position in the competitive foldable smartphone market.
The move to 45W charging for the Z Fold 8 represents a significant step forward for Samsung’s foldable devices. As the technology matures, consumers are demanding improvements in all areas, including battery life and charging speed. The Z Fold 8 appears to be responding to those demands, offering a more competitive and convenient user experience. The coming months will reveal further details about the device, but the initial reports suggest a compelling upgrade for Samsung’s flagship foldable.
