The Samsung Galaxy S25 series, expected to debut in January 2024, is set to introduce a notable update for wireless charging enthusiasts: support for the Qi2 wireless charging standard. This new technology promises more efficient wireless charging, thanks to the integration of magnets that align the device and charger.
For context, Apple has supported Qi2 wireless charging since the iPhone 12 series. But the HMD Skyline is the only Android phone that currently supports the Qi2 standard. Samsung’s decision to integrate Qi2 into its flagship devices is expected to make a significant impact on the broader Android ecosystem.
The Galaxy S25 series’ adoption of Qi2 will enable faster, more efficient wireless charging up to 15W. However, it’s worth noting that Qi2 support will be limited to 15W charging speed, which is relatively modest compared to the wired charging speeds many Android phones now offer.
Wired charging speed and battery capacity:
While the Qi2-based magnetically attachable wireless charging is a highlight, it seems Samsung isn’t prioritizing significant advancements in wired charging speed for the Galaxy S25 series.
According to the FCC database, the Galaxy S25 model will continue to use the EP-TA800 charging adapter, which supports only 25W fast charging. This is a far cry from its competitors, which have reached much faster-wired charging speeds. Even Apple has matched Samsung’s wired charging rates in recent years.
On the other hand, the Galaxy S25+ and S25 Ultra models are expected to feature 45W fast charging, offering a faster option for users who prefer wired charging.
In terms of battery capacity, it seems that Samsung is not planning to make any major changes either. Unlike most of its Chinese competitors, which have adopted the Si/C battery tech (that results in much higher capacity within the same volume), According to a previous rumor, Samsung will stick to the same battery capacities as the S24 series, which means only iterative improvement in battery life that is due to the more efficient and more expensive Snapdragon 8 Elite chip.
