Fold Devices See Significant Wired Charging Upgrade
Recent regulatory filings indicate that Samsung's next generation of foldable phones, specifically the Galaxy Z Fold 8 and a potential Galaxy Wide Fold, are slated to receive a significant boost in wired charging speeds. These devices are now expected to support 45W wired charging, a notable jump from the long-standing 25W standard that has characterized the Fold lineup since the Galaxy Z Fold 2. This marks the first substantial increase in wired charging capability for the Fold series in approximately six years.
Regulatory listings from China's 3C authority point to a new era for Samsung's book-style foldables, aiming to close the gap with their S-series counterparts and a competitive market landscape.
While the Fold 8 and Wide Fold appear poised for this upgrade, the Galaxy Z Flip 8 is anticipated to retain its current 25W wired charging. This creates a divergence in charging technology across Samsung's foldable offerings, with the more premium Fold models receiving the enhanced speeds.

Persistent Charging Lag Addressed
The upgrade to 45W wired charging for the Fold 8 and Wide Fold addresses a persistent limitation that has left Samsung's foldable devices trailing behind broader smartphone trends. For years, the Fold series has remained at 25W, a speed that has become comparatively slow as competitors, including Samsung's own Galaxy S flagship devices, have moved towards faster charging solutions. The Galaxy S26 Ultra, for instance, is reported to support even higher charging rates beyond 45W. This shift suggests Samsung is responding to both internal development pressures and external competition, particularly in the demanding foldable segment where power-hungry displays necessitate more frequent charging.
Design and Battery Expectations
Beyond charging, leaks suggest potential changes for the Galaxy Z Fold 8. CAD renders have emerged depicting the "Wide Fold" model with a form factor resembling a small tablet when unfolded. The standard Galaxy Z Fold 8 is expected to feature a 6.5-inch cover screen and a larger 8-inch inner display. Battery capacity for the Fold 8 is also rumored to increase, potentially from the 4,400 mAh seen in recent models to around 5,000 mAh, with the Wide Fold possibly accommodating a 4,800 mAh battery. These potential increases, coupled with faster charging, could significantly reduce charging times; a full charge for the Galaxy Z Fold 7, which took approximately 83 minutes, might be reduced to under an hour for the Fold 8.

Background: A Stagnant Standard
Samsung's Galaxy Z Fold line has adhered to a 25W wired charging standard for a considerable period. Following the original Galaxy Fold's 15W charging, the Galaxy Z Fold 2 established the 25W benchmark, a figure that has been consistently maintained across subsequent generations, including the Galaxy Z Fold 7. This stagnation occurred despite advancements in processing power, display technology, and increasing battery demands inherent in foldable form factors. Meanwhile, Samsung's non-foldable Galaxy S series has seen charging speeds increase over the years, with some models reaching and surpassing the 45W mark. This disparity highlights a long-standing prioritization of charging speed in Samsung's traditional flagship lineup over its more innovative, yet consistently incremental, foldable devices.
