Samsung’s Galaxy Z Fold 8 appears set to receive a significant charging speed upgrade, jumping to 45W wired charging based on a fresh regulatory filing out of China. The certification, tied to two model numbers associated with the next-generation foldable, would nearly double the charging capability of recent Fold devices and address one of the longest-running complaints from Samsung’s foldable user base. If the filing holds, it signals that Samsung is finally closing the gap with competitors, which have offered faster charging in large-screen foldables for years.
What the China 3C Filing Reveals
A China 3C regulatory certification has surfaced for two device model numbers, SM-F9710 and SM-F9760, both believed to correspond to variants of the Galaxy Z Fold 8. The filing lists support for 15V/3A wired charging, which translates to 45W of power delivery. That is a clear step up from the 25W ceiling that Samsung has maintained across its recent Fold lineup, including the Galaxy Z Fold 6.
China’s 3C certification process is a mandatory safety and quality check for electronics sold in the Chinese market. Devices that pass through it typically carry specifications close to their final production versions, which makes the filing a reliable early indicator of real hardware capabilities. The two model numbers suggest Samsung may be preparing both a domestic Korean variant and an international or China-specific version, consistent with how the company has handled prior Fold releases.
Samsung has not issued any official confirmation of the Fold 8’s charging specs, and no independent teardown or lab test has verified the real-world performance of these certified prototypes. The gap between a regulatory filing and a finished retail product can sometimes produce changes. Still, 3C certifications have historically been accurate predictors of final charging hardware in Samsung devices.
Why 45W Matters for Foldables
The jump from 25W to 45W is not just a number on a spec sheet. In practical terms, doubling the wattage can cut recharge times substantially, especially during the first 50 to 60 percent of a battery cycle where fast charging protocols deliver the most benefit. For a device like the Fold, which carries a larger battery than a standard slab phone to power its expansive inner display, faster charging directly affects how usable the phone is during a busy day.
Samsung already offers 45W charging on its Galaxy S series flagships, including the Galaxy S24 Ultra. The fact that its foldables have lagged behind its own slab phones on this front has been a persistent source of frustration among Fold buyers, who pay a premium price but receive mid-range charging speeds. Bringing the Fold 8 in line with the S series would eliminate one of the clearest spec disparities between Samsung’s two flagship tiers.
The competitive pressure is real. Chinese manufacturers like Oppo and Honor have shipped foldables with charging speeds of 67W and higher for multiple product cycles. Samsung’s 25W cap made its Fold devices look conservative by comparison, even as the company led global foldable sales volume. A 45W upgrade does not leapfrog those rivals, but it removes a talking point that has dogged Samsung in head-to-head reviews.
Broader Fold 8 Expectations
Charging speed is not the only area where the Fold 8 is expected to improve. Reporting on the device suggests Samsung is targeting a broader set of upgrades that Fold owners have requested for years, including a thinner profile and improved battery life. These changes, if they materialize together, would represent the most meaningful generational leap the Fold line has seen since its early iterations.
A thinner body paired with faster charging creates an interesting design tension. Slimmer devices typically have less internal volume for battery cells, which can mean smaller capacity. Faster charging partially offsets that trade-off by letting users top up more quickly during short breaks. Samsung’s engineering challenge will be balancing thinness, battery size, and thermal management, since pushing 45W into a slim foldable generates more heat than a 25W charge cycle in a thicker body.
The thermal question is worth watching closely. Samsung’s existing 45W implementation in the Galaxy S series uses adaptive charging curves that throttle speed as the battery heats up. A foldable’s hinge mechanism and layered display stack leave less room for heat dissipation than a traditional phone chassis. Whether the Fold 8 can sustain 45W speeds for a meaningful portion of the charge cycle, or whether it quickly drops to lower wattage, will determine how much real-world benefit users actually see.
What This Means for Buyers
For anyone considering a foldable purchase later this year, the charging upgrade shifts the calculus. One of the strongest arguments against the Fold line has been that its premium price, typically north of $1,800 at launch, did not come with premium charging performance. A Fold 8 with 45W wired charging would remove that objection and bring the device closer to parity with Samsung’s own Galaxy S flagships on everyday convenience.
The upgrade also matters for the growing number of users who treat their Fold as a productivity device rather than a novelty. Professionals who rely on the large inner screen for multitasking, document editing, or video calls need a phone that can recover charge quickly between meetings. Moving from 25W to 45W could mean the difference between a phone that needs an hour on a charger and one that gets back to a usable level in 30 minutes or less.
There is a broader signal here about Samsung’s strategy. The company has dominated foldable sales globally, but growth in the category has slowed as early adopters have already bought in. To attract new buyers and convince existing Fold owners to upgrade, Samsung needs to deliver spec improvements that feel tangible in daily use, not just incremental camera tweaks or processor bumps. Faster charging is exactly the kind of practical, felt improvement that can move purchasing decisions.
