Samsung Galaxy Z Fold 8 May Raise Wireless Charging to 20W From 15W

Q: With rivals offering 50W wireless charging, is Samsung's 20W Fold 8 upgrade too little, too late?

Yes — as a headline spec, Samsung’s reported 20W wireless charging for the Galaxy Z Fold 8 looks conservative in 2026. The upgrade matters because Samsung’s book-style Fold line has been stuck at 15W since the Z Fold 4, so moving to 20W is at least a long-overdue improvement. But rivals are already much further ahead. Devices from Motorola, Honor and Oppo have pushed wireless charging into the 50W range or beyond, and even the open Qi2.2 ecosystem is moving toward 25W as a mainstream benchmark. Against that backdrop, 20W does not look class-leading on a phone expected to cost around $1,999. Samsung does have some context in its favor. Faster wireless charging is heavily constrained by heat, coil alignment and battery longevity, especially in thin foldables. The Fold 8 is also rumored to get a larger 4,800mAh battery, while the Fold 8 Ultra is expected to pair 20W wireless with a 5,000mAh battery and 45W wired charging. That suggests Samsung may be using the extra wireless power mainly to offset a bigger battery rather than to dramatically cut charging times. So the answer depends on the standard used. By Samsung’s own history, 20W is a meaningful step. By the premium foldable market’s pace, it is modest and late. For buyers who value convenience and thermal stability, it may be enough. For buyers comparing spec sheets with Chinese rivals, Samsung still looks behind.

A new leak says Samsung’s Galaxy Z Fold 8 will support 20W wireless charging, ending a run of 15W speeds across the Fold 4 through Fold 7.
The 5W bump would be the first wireless-charging upgrade in Samsung’s book-style foldables in years, though it remains modest versus faster-charging Chinese rivals.
Recent leaks also point to a 4,800mAh battery, up from 4,400mAh on the Z Fold 7, which could leave real-world charging times close to the current model despite the higher wattage.
Samsung’s rumored Galaxy Z Fold 8 Ultra may match or exceed 20W wireless charging, but no specific charging details for that model have surfaced yet.
