Samsung Galaxy S25 Certification Hints No Fix for Galaxy S24’s Charging Issue

Samsung Galaxy S25 Certification Suggests Charging Speeds Remain the Same

The Samsung Galaxy S24 lineup is widely regarded as one of the top Android phone series, but it falls behind rivals when it comes to charging speeds. Unfortunately, recent certifications suggest that the Samsung Galaxy S25 series might not bring any improvements in this area, maintaining the same charging limits as its predecessor.

Galaxy S25: No Major Changes in Charging Speeds

According to recent FCC (Federal Communications Commission) certifications, as spotted by 91Mobiles, the Galaxy S25 and its siblings—Galaxy S25 Plus and Galaxy S25 Ultra—are expected to charge at the same speeds as the current models.

• Galaxy S25: 25W charging (same as Galaxy S24)
• Galaxy S25 Plus and Ultra: 45W charging (same as Galaxy S24 Plus and Ultra)

While these certifications technically reflect the power adapter speeds, they typically align with the device’s charging capabilities.

Falling Behind the Competition

This stagnant approach leaves Samsung lagging behind competitors like Xiaomi and OnePlus, which have significantly advanced their charging technology:

• Xiaomi 14T Pro: 120W wired, 50W wireless charging
• OnePlus 13: 100W wired, 50W wireless charging

Confusion Around Wireless Charging

The FCC documentation hints at potential changes to wireless charging capabilities, particularly for the base Galaxy S25 model, which some interpret as offering 9W wireless charging—a downgrade from the Galaxy S24’s already modest 15W.

However, a closer analysis by leaker @Jukanlosreve clarifies that the 9W refers to reverse wireless charging (used to charge other devices with your phone), while standard wireless charging likely remains at 15W. This actually marks an improvement for reverse wireless charging, which maxed out at 4.5W on the Galaxy S24.

Lack of UWB Support

Another notable point in the certification is the absence of UWB (ultra-wideband) technology in the base Galaxy S25 model. This wireless protocol, used for features like unlocking car doors and precise device tracking, remains exclusive to the Galaxy S25 Plus and Ultra models, consistent with the Galaxy S24 lineup.

A Familiar Picture

Overall, the FCC certifications suggest minimal changes between the Galaxy S25 series and its predecessor, at least in terms of charging and UWB capabilities. While the information is yet to be confirmed, the Galaxy S25 series is expected to launch in January 2025, when Samsung will officially reveal its latest flagship devices.
