Samsung Galaxy S25 Edge Compromises on Battery and Charging for Ultra-Thin Design, Certification Shows

Samsung’s upcoming Galaxy S25 Edge, expected to launch in April 2025, is shaping up to be one of the thinnest flagship phones of the year.

However, this sleek design comes with compromises in key areas, particularly battery capacity and charging speed.

According to a new 3C certification, the Galaxy S25 Edge will feature a relatively small 3,900mAh battery and support charging speeds up to 25W.

In comparison, the standard Galaxy S25 is expected to ship with a 4,000mAh battery. The decision to use a smaller battery is a direct result of the device’s ultra-thin design, which limits space for larger components.

Despite this, Samsung has yet to adopt newer battery technologies like silicon-carbon, which could have allowed for larger batteries without sacrificing thickness. Many Chinese manufacturers have already transitioned to this technology, enabling them to pack larger 6,000mAh+ batteries into similarly sized devices.

The charging speed of 25W is also a notable limitation. While this is sufficient for many users, it lags behind the competition, which has moved to faster charging speeds in recent years.

Samsung likely capped the charging speed to prevent overheating and potential damage to the device’s internal components, preserving the longevity of the battery.

Despite these limitations, the Galaxy S25 Edge will feature the latest Snapdragon 8 Elite chipset, with performance cores running at 4.47GHz. However, early benchmarks show that the device struggles in multi-core performance, possibly due to software optimization or the constraints of its thin design.

In summary, the Galaxy S25 Edge will offer a premium, ultra-thin design, but users should be prepared for compromises in battery life and charging speed compared to other devices in the Galaxy S25 lineup.
