Samsung is gearing up to release the Galaxy S26 Edge with an emphasis on battery capacity and a more streamlined design compared to the Galaxy S25 Edge. The company is expected to leverage new battery materials technology to enable these improvements. However, there is some ambiguity surrounding the specific capacity of the battery. While an earlier report indicated a 4,200mAh capacity, a recent update suggests that the device may feature a 4,400mAh battery. In comparison, the current Galaxy S25 Edge is equipped with a 3,900mAh battery and has a thickness of 5.8mm.
Samsung Galaxy S26 Edge Might Feature a 4,400mAh Battery
According to a recent post on X by tipster PhoneArt (@UniverseIce), the Samsung Galaxy S26 Edge could include a 4,400mAh battery. Another source had previously indicated that the phone might come with a battery rated at 4,078mAh, with a typical capacity of around 4,200mAh.
The battery information I got for the S26 Edge is 4400mAh. There seems to be some conflict here, I will double-check the information.

The tipster has noted the discrepancies in the information available and has promised to verify the data. Consumers are encouraged to remain cautious until further official announcements are made.
Moreover, the Galaxy S26 Edge is anticipated to be slimmer than its predecessor, with the reduction in thickness likely achieved through innovative battery technology. The South Korean tech giant is rumored to be integrating a silicon-carbon battery, which would supersede the lithium-ion technology currently in use.
In terms of camera capabilities, the Samsung Galaxy S26 Edge is expected to sport a 50-megapixel ultra-wide lens, marking a significant upgrade from the 12-megapixel camera found in the Galaxy S25 Edge.
Additionally, European variants of the Galaxy S26 series are likely to feature Samsung’s proprietary Exynos 2600 SoC. The company has confirmed that this chipset will be the first to be manufactured using its 2nm GAA (Gate-All-Around) process, reflecting its ongoing commitment to advanced semiconductor technology.
