Samsung Galaxy S27 Charging Speed Revealed: Still 25W

Leaks continue to emerge regarding Samsung's highly anticipated new flagship series, the Galaxy S27. Most recently, significant details about the charging speed of the base model have appeared in certification records. Documents approved by UL Solutions (Demko) reveal that the Samsung Galaxy S27 will maintain the 25W wired charging speed, consistent with previous generations. This development may lead to disappointment for users expecting faster charging capabilities.

Why it matters

Samsung has been utilizing 25W charging technology in its base Galaxy S models for many years. After reaching this speed with the Galaxy S20 series, the company maintained the same value through the Galaxy S21, S22, S23, and S24 series. The continuation of this trend with the Galaxy S27 is noteworthy, especially in a period of increasing competition in the mobile technology sector. While some competitors offer higher charging speeds on certain models, Samsung's decision not to advance the charging speed on the entry-level version of its flagship series might not meet user expectations regarding charging times. This raises questions about whether it's a strategic choice by Samsung or a cost-driven decision.

What it means for you

The model number SM-S952B/DS, listed in the certification records and relevant to the Turkish market, indicates that this charging speed will be valid globally, including in Turkey. Although Samsung Turkey has not yet made an official announcement, these certification details suggest that users in Turkey will continue to experience 25W charging with the Galaxy S27. Compared to the higher charging speeds offered by the company in its mid-range devices, maintaining this speed on the base version of the flagship model might raise some questions regarding the price-performance balance. Consumers may need to consider this charging speed when making their purchasing decisions for the new phone.

Technical Details and Expectations

The certifications, DK-187425-UL and DK-187435-UL, approved by UL Solutions (Demko) on October 23, 2026, list a Samsung device with the model number SM-S952. Based on the previous generation's SM-S942 from the Galaxy S26 series, this model number is believed to belong to the standard Galaxy S27. The documents specify 9V and 2.77A, which translates to approximately 24.9W, aligning with Samsung's marketed 25W charging power. It's important to note that these certifications represent the maximum input power tested in a laboratory setting. The actual charging time of the phone may vary depending on battery capacity and Samsung's software-based charging optimizations. Information regarding wireless charging speed or battery capacity is not yet available; however, it is expected that the 15W wireless charging from the Galaxy S26 might continue.

Other Models May Differ

The standard Samsung Galaxy S27 model might not be the only one with 25W charging. According to available information, higher-tier models in the series are expected to feature different charging speeds. Reports based on China's 3C certification filings suggest that the Galaxy S27+ will support 45W wired charging, while the Galaxy S27 Pro and Galaxy S27 Ultra will come with 60W wired charging support. This indicates that Samsung is implementing a tiered approach to charging speeds within its product lineup, aiming to offer more advanced technologies in its top-tier models. The Ultra model, in particular, is anticipated to be a strong contender in terms of battery and charging technology.

Samsung has not yet released an official date for the introduction of its new flagship series. However, following the company's traditional schedule, the Galaxy S27 series is expected to be unveiled in late January or early February with four distinct models: the standard, Plus, Pro, and Ultra.
