The rumor mill for Samsung’s next-generation Galaxy S27 series is already in full swing, and a fresh certification has just surfaced online. The base Galaxy S27 and the larger Galaxy S27+ have been spotted on China’s 3C certification database, giving us our first concrete look at their charging capabilities. This development adds another piece to the puzzle for tech enthusiasts eagerly awaiting the next flagship lineup from the Korean giant.
According to the 3C listing, the standard Galaxy S27, bearing the model number SM-S9520, will support 25W wired charging. This is a notable point of discussion, as it mirrors the charging speed found on its predecessor, the Galaxy S26, and even harks back to the Galaxy S20, which launched several years ago. While some might have hoped for a significant upgrade in charging technology, Samsung appears to be sticking with a familiar, albeit slower, standard for its base model.
On the other hand, the Galaxy S27+, with model number SM-S9560, is listed with support for 45W wired charging. This is a step up from the standard model and aligns with the trend seen in the previous generation, where the Plus variant offered faster charging than the base model. This differentiation suggests Samsung is continuing its strategy of reserving more advanced features for its higher-tier devices, encouraging users who want the fastest charging experience to opt for the Plus or Ultra models.
What the 3C Certification Reveals
The 3C certification is a mandatory approval for products to be sold in China, and it often leaks ahead of official launches, providing early insights into a device’s specifications. For the Galaxy S27 series, the listings confirm not only the model numbers but also the charging speeds, which are crucial for consumers who prioritize battery life and quick top-ups.
It’s worth noting that these charging speeds are not groundbreaking. In an era where competitors like Xiaomi, OnePlus, and Oppo are pushing 100W, 150W, or even 200W charging, Samsung’s 25W and 45W figures might seem conservative. However, Samsung has historically prioritized battery longevity and thermal management over raw charging speeds, and these numbers are consistent with that philosophy. The company seems to be focusing on other aspects, such as battery efficiency and software optimization, to deliver a reliable user experience.
Galaxy S27: 25W Charging – A Familiar Story
The Galaxy S27’s 25W charging is a double-edged sword. On one hand, it’s a proven technology that is safe, efficient, and unlikely to cause overheating issues. On the other hand, it lags behind the industry’s current standards, and for a flagship device in 2026, it might feel underwhelming to some power users.
For comparison, the Galaxy S26 also supported 25W, and the Galaxy S20 did the same back in 2020. This means that for the past six years, Samsung’s base models have not seen an increase in wired charging speed. While the battery capacity may have increased over time, the charging rate has remained static. This could be a point of contention for fans who expect faster charging with each new generation.
However, it’s also possible that Samsung is making up for this in other ways. The Galaxy S27 is rumored to come with a more efficient chipset, possibly the Exynos 2600 or a Snapdragon 8 Gen 5, depending on the region. A more efficient processor would mean better battery life, which could offset the need for extremely fast charging. Additionally, Samsung’s adaptive charging technology ensures that the battery is protected, extending its overall lifespan.
Galaxy S27+: 45W Charging – A Step Above
The Galaxy S27+ is set to offer 45W wired charging, a feature that was also present on the Galaxy S26+. This speed is more competitive and can fully charge a typical 5,000mAh battery in under an hour, which is respectable. The 45W charging is a better fit for a larger phone, as it can handle the bigger battery capacity without generating excessive heat.
The Plus model has always been the middle child in Samsung’s lineup, offering a balance between the compact base model and the feature-packed Ultra. With 45W charging, the S27+ becomes a more attractive option for users who want faster top-ups but don’t necessarily need the S Pen or the advanced camera system of the Ultra.
It’s also likely that the Galaxy S27+ will feature a larger battery than its predecessor, possibly in the 5,000mAh to 5,500mAh range, to justify the 45W charging. This would be a welcome upgrade, as battery life is often a primary concern for smartphone users.
Other Expected Features of the Galaxy S27 Series
While the 3C certification only confirms charging speeds, a slew of other leaks and rumors have painted a more complete picture of what to expect from the Galaxy S27 lineup. Here are some of the most anticipated features:
- Display: The Galaxy S27 is expected to feature a 6.3-inch AMOLED display with a 120Hz refresh rate, while the S27+ might come with a 6.7-inch panel. Both are likely to offer peak brightness levels exceeding 2,500 nits, making them highly legible in direct sunlight.
- Processor: Samsung is expected to use the next-generation Exynos 2600 chipset in most regions, with the Snapdragon 8 Gen 5 reserved for select markets like the US and China. The Exynos chip is rumored to be built on a more advanced 2nm process, promising better performance and efficiency.
- Camera: The camera setup is likely to see incremental improvements, with the base models featuring a 50MP main sensor and a 12MP ultra-wide. The Ultra model, however, might get a periscope zoom lens with 10x optical zoom, building on the success of the S24 Ultra.
- Software: The Galaxy S27 series will run on Android 16 out of the box, with Samsung’s One UI 7.0 on top. Expect a host of AI-powered features, including advanced photo editing, real-time translation, and improved battery management.
- Design: Rumors suggest a more refined design with thinner bezels and a titanium frame, similar to the Galaxy S24 Ultra. The phones are also expected to be more durable, with an IP68 rating for water and dust resistance.
Battery and Charging: What’s Missing?
One of the most significant omissions in the Galaxy S27 series might be the lack of wireless charging improvements. While wired charging speeds have been confirmed, there is no word yet on whether Samsung will upgrade its wireless charging from the current 15W standard. In a world where many competitors offer 50W or even 80W wireless charging, Samsung’s 15W seems outdated.
Another area of concern is the absence of a charger in the box. Samsung has been excluding chargers from its flagship phones since the Galaxy S21 series, and it’s unlikely that the S27 will reverse this trend. This means that users who want to take advantage of the 45W charging will need to purchase a compatible charger separately, which adds to the overall cost.
However, Samsung might introduce a new battery technology, such as silicon-carbon batteries, which offer higher energy density and faster charging without compromising on safety. If this is the case, the 25W and 45W figures might be conservative estimates, and the actual charging speeds could be higher when using compatible chargers.
