Samsung’s Premium Foldables Won’t Get Faster Charging Despite Cheaper Models Offering 45W
As Samsung continues to push the boundaries of foldable technology, one might expect its most premium foldables—the Galaxy Z Flip7 and Z Fold7—to get a significant charging upgrade. However, that is not the case. Despite the newly launched $400 Galaxy A36 supporting 45W fast charging, Samsung appears unwilling to extend the same benefit to its flagship foldables.
According to China’s 3C certification, the upcoming Samsung Galaxy Z Flip7 (SM-F7660) and Galaxy Z Fold7 (SM-F9660) will stick with 25W charging—the same standard as their predecessors.
Certification Confirms 25W Charging Limit
Recent regulatory filings confirm that the Galaxy Z Flip7 and Z Fold7 will support charging at 9V, 2.77A, which translates to a maximum charging speed of 25W.
📌 Key Details from Certification:
✔ Devices Certified: Galaxy Z Flip7 (SM-F7660) & Galaxy Z Fold7 (SM-F9660)
✔ Charging Speed: 25W (9V, 2.77A)
✔ No Charger in the Box: Samsung continues its trend of omitting chargers from flagship devices
✔ Compatible Charger: EP-TA800, a model dating back to the Galaxy S10 era
This confirmation dashes any hopes of a 45W fast-charging upgrade for Samsung’s most expensive foldable smartphones.
Battery Capacity: Small Bump for Flip7, No Change for Fold7
While faster charging is off the table, Samsung is making minor battery capacity improvements.
- Galaxy Z Fold7: Expected to retain the same 4,400mAh battery as the Z Fold6.
- Galaxy Z Flip7: Getting a slight battery increase to 4,174mAh, up from 4,000mAh in the Z Flip6.
Despite the small upgrade for the Flip7, the lack of faster charging means that users will still face longer charging times compared to competitors offering 45W or higher speeds.
Why Samsung Isn’t Upgrading Charging Speeds?
Samsung’s strict battery policies suggest that fast charging above 25W is reserved for devices with batteries over 4,500mAh—a capacity threshold that neither the Z Flip7 nor the Z Fold7 meets.
Additionally, Samsung has been slow in adopting Silicon-Carbon battery technology, which could have allowed higher battery capacity within the same physical space. This is another missed opportunity, especially as competitors like OnePlus, Xiaomi, and even Apple push for better battery innovations.
Launch Timeline: When Will the Galaxy Z Flip7 & Z Fold7 Be Unveiled?
Samsung is expected to unveil the Galaxy Z Flip7 and Z Fold7 in July 2025, following its usual mid-year Unpacked event timeline.
Meanwhile, rumors suggest that the Galaxy Z Flip FE (Fan Edition) might be delayed until the Exynos 2500 chipset is available, meaning fans hoping for a cheaper foldable alternative may have to wait longer.
