Samsung’s 45w foldable bet chases apple’s shadow

The race to keep foldables alive just got a lopsided lane change: Samsung will strap 45-watt charging to the Galaxy Z Fold 8 and its rumored Wide sibling this summer, a jump from the 25W crawl that has dogged every book-style Galaxy since 2019.

The numbers look good—until you look around

Forty-five watts is exactly the speed the Galaxy S26 Ultra left behind in February when it leapt to 60W. Motorola’s incoming Razr Fold already flirts with 80W, and Oppo, Honor, and Vivo have been flirting with triple-digit wired figures for two product cycles. Translation: Samsung’s “upgrade” lands the company in the middle of a pack it once led.

Battery math tells the rest. The Z Fold 8 is expected to swallow a 5,000mAh cell, up from 4,400mAh on the Z Fold 7, while the Wide model settles near 4,800mAh. A back-of-the-envelope calc—same voltage curve, same dual-cell layout—puts a zero-to-full somewhere near 60 minutes, down from 83 on the current generation. Respectable, yes. Record-breaking, no.

Apple’s shadow is the real timer

None of this would feel urgent if Cupertino weren’t folding its first iPhone this September. Supply-chain manifests show a titanium-shelled, 5,000mAh device testing at 35W, but apple’s tight silicon-to-battery integration could squeeze more mileage out of every watt. Samsung’s answer can’t be wattage alone; it has to be efficiency, durability, and a price that doesn’t make buyers feel like beta testers.

History offers a warning. When the original Razr reboot launched in 2020, it shipped with 15W bricks and a $1,499 tag. Sales cratered. Samsung itself sold fewer than 10 million foldables last year, according to Counterpoint, while the company’s own S-series moved 31 million. Faster charging alone won’t bridge that gap, but slower charging would widen it overnight.

Bottom line: samsung is playing defense

Forty-five watts keeps the Z Fold 8 from embarrassing headlines, nothing more. The real fight will hinge on hinge engineering, app continuity, and whether Samsung dares to undercut apple’s rumored $1,699 entry price. Speed matters, but only if the phone survives the first 365 folds—and the first glance at an apple Store table.
