Samsung is once again making headlines with early leaks about its upcoming flagship smartphone, the Galaxy S26 Edge. The latest report suggests that Samsung is aiming to combine a slimmer form factor with a significantly larger battery capacity. This could make the Galaxy S26 Edge a compelling upgrade over its predecessor, the Galaxy S25 Edge.

Key Leak Highlights

Galaxy S26 Edge tipped to feature a larger 4,400mAh battery.

Previous leaks suggested a 4,200mAh capacity.

Galaxy S25 Edge had a 3,900mAh battery and measured 5.8mm in thickness.

Samsung expected to use new battery material tech for a thinner design.

Silicon-carbon battery rumored to replace the current lithium-ion cell.

Camera upgrade expected: 50MP ultra-wide shooter.

European models likely to use Exynos 2600 SoC built on 2nm GAA process.

Battery Upgrade: 4,400mAh Likely

According to well-known tipster @UniverseIce (PhoneArt), the Samsung Galaxy S26 Edge could come with a 4,400mAh battery. This is a notable increase from the 3,900mAh battery in the Galaxy S25 Edge. A previous leak had pegged the battery at 4,200mAh, with a rated capacity of 4,078mAh. Although the information is still conflicting, the larger battery capacity would represent a substantial improvement in battery life.

Thinner Yet More Powerful

Interestingly, Samsung is expected to achieve this battery upgrade while making the S26 Edge thinner than its predecessor. The Galaxy S25 Edge was already slim at 5.8mm, and Samsung is tipped to make the S26 Edge even sleeker. This feat may be accomplished through new battery material technology—potentially silicon-carbon batteries, which offer better energy density than traditional lithium-ion cells.

Camera Enhancements

In the optics department, the Galaxy S26 Edge is rumored to include a 50-megapixel ultra-wide camera. This would be a marked upgrade from the 12-megapixel ultra-wide sensor found in the Galaxy S25 Edge, signaling Samsung’s intention to enhance camera capabilities for its upcoming premium device.

Performance: 2nm Exynos 2600 SoC

Another key highlight is the expected chipset upgrade. Samsung recently confirmed the development of the Exynos 2600, its first SoC built using the company’s 2nm Gate-All-Around (GAA) process. The European variants of the Galaxy S26 series are likely to feature this in-house chip, which promises better power efficiency and enhanced performance.

Conclusion

While these early leaks should be taken with caution until official confirmation arrives, the rumored improvements in battery, design, camera, and performance paint an exciting picture of the Galaxy S26 Edge. Samsung appears to be pushing the boundaries of what’s possible in a slim flagship device—potentially redefining the premium smartphone experience in 2025.
