Galaxy S27 Pro and S27 Ultra Get 60W Charging in 3C Filing, With 5,200mAh and 5,700mAh Batteries
Two Samsung phones listed with China's 3C certification body, model numbers SM-S957 and SM-S958, are rated for 60W wired charging at 20V/3A. Those model numbers have been tied to the Galaxy S27 Pro and Galaxy S27 Ultra, and separate battery certifications point to capacities of roughly 5,200mAh and 5,700mAh, which would be the Ultra line's first real battery increase in five generations.
This is a leak, not an announcement. Samsung has confirmed nothing about the Galaxy S27 series, which is expected in early 2027. But certification filings are paperwork a manufacturer has to submit before it can sell a phone in China, so they tend to be among the more dependable early signals.
What the 3C filings actually show
The charger rating is the firm part. Both phones are listed at 20 volts and 3 amps, which multiplies out to 60W. For the Ultra, that was widely expected, since the Galaxy S26 Ultra already charges at 60W. For the Pro, it was an open question until now.
The battery figures come from a second set of 3C listings for two cells whose model numbers line up with the Pro and Ultra. Those list 5,087mAh and 5,534mAh. That matching step is an inference by the people who found the listings, and it is the softer half of this leak.
Why 5,087mAh becomes 5,200mAh
Certification documents record a battery's rated capacity, the minimum every cell off the line must reach. Samsung's spec sheets quote the typical capacity, which is a little higher. The gap is usually a couple of percent.
- Galaxy S27 Pro (SM-S957): 5,087mAh rated, likely sold as about 5,200mAh, 60W wired
- Galaxy S27 Ultra (SM-S958): 5,534mAh rated, likely sold as about 5,700mAh, 60W wired
So when you compare the leak to a Samsung product page, compare the 5,200 and 5,700 figures, not the raw filing numbers. Neither number is final until Samsung publishes a spec sheet.
How the whole S27 lineup stacks up so far
Earlier this month the same regulator listed the other two models. Put together, the leaked charging speeds look like this:
- Galaxy S27: 25W
- Galaxy S27 Plus: 45W
- Galaxy S27 Pro: 60W
- Galaxy S27 Ultra: 60W
The gap at the bottom is the awkward part. The base model would still charge at less than half the speed of the Pro, the same 25W ceiling Samsung's smallest flagship has carried for years. Anyone who cares about top-up speed now has a clear reason to look above the entry model.
The Ultra's 5,000mAh streak would end
Samsung has put a 5,000mAh battery in every Ultra since the Galaxy S21 Ultra in 2021, including this year's S26 Ultra. A move to around 5,700mAh would be a 14% jump in one step. Rivals in China have pushed well past 6,000mAh using silicon-carbon cells, so Samsung would still not lead on raw capacity, but the change would be the biggest the Ultra has seen in years.
More capacity does not automatically mean longer battery life. The chip, display and software tuning matter as much, and none of those are confirmed. If you are weighing the current model instead, our iPhone 17 vs Galaxy S26 Ultra comparison covers how the S26 Ultra's battery holds up today.
What to expect next
Samsung normally unveils its S-series flagships between January and February. Before that, expect more certifications, and eventually regional listings that confirm storage and colours. We are tracking the rest in our Galaxy S27 release date, price and leaks roundup.
One practical note for buyers: Samsung's faster charging modes rely on USB Power Delivery with PPS, so a generic USB-C brick may not reach the full 60W. If you plan to upgrade, a PPS-capable 60W or higher charger is the one to look for.
Frequently Asked Questions
How fast will the Galaxy S27 Ultra charge?
China's 3C certification lists the Galaxy S27 Ultra (model SM-S958) at 20V/3A, which is 60W wired charging. That matches the Galaxy S26 Ultra. Samsung has not confirmed the figure yet.
What is the Galaxy S27 Ultra battery capacity?
A 3C battery listing linked to the S27 Ultra shows a rated capacity of 5,534mAh, which would likely be marketed as about 5,700mAh. That would replace the 5,000mAh battery Samsung has used in every Ultra since the Galaxy S21 Ultra. It remains a leak until Samsung publishes specs.
Does the Galaxy S27 Pro support 60W charging?
Yes, according to the 3C listing for model SM-S957, which has been tied to the Galaxy S27 Pro. It is rated at 20V/3A, the same 60W as the Ultra. Its battery is listed at 5,087mAh rated, or roughly 5,200mAh typical.
How fast do the Galaxy S27 and S27 Plus charge?
Earlier 3C filings this month showed 25W wired charging for the base Galaxy S27 and 45W for the S27 Plus. That leaves the entry model at under half the speed of the Pro and Ultra.
When will the Galaxy S27 series launch?
Samsung has not announced a date, but the S27 series is expected in early 2027. Samsung usually unveils its S-series flagships between January and February, with sales starting a few weeks later.
