Next Samsung Edge Phone to Feature Revolutionary Battery Technology
Samsung embraced the ultra-thin smartphone trend with the introduction of the Galaxy S25 Edge this year. While this model didn’t replace existing Galaxy S25 lineup devices, it was positioned as a premium addition to the series. However, industry speculation suggests Samsung may be planning to streamline its product lineup by potentially eliminating the traditional “Plus” model in favor of expanding the Edge series.
Current Galaxy S25 Edge Specifications
This year’s Galaxy S25 Edge already impresses with its ultra-slim profile measuring just 5.8mm thick. The device features a 200MP primary camera and a 3,900 mAh battery, establishing it as both a visual standout and a capable performer in Samsung’s premium lineup.
Exciting Galaxy S26 Edge Leaks
Prominent leaker IceUniverse has revealed compelling details about next year’s Galaxy S26 Edge, suggesting it will be a highly anticipated upgrade. According to the leak, the S26 Edge will feature two major improvements over its predecessor:
Enhanced Battery Capacity
The Galaxy S26 Edge will reportedly include a larger battery than the current S25 Edge model. While specific capacity numbers weren’t disclosed, this increase would address one of the key concerns users have with ultra-thin devices – battery life.
Even Slimmer Profile
Perhaps more impressively, the S26 Edge is expected to be even thinner than the already slim 5.8mm S25 Edge. Rumors suggest it could approach or even surpass the 5.5mm thickness mark, making it one of the thinnest smartphones on the market.
Technology Behind the Improvements
According to IceUniverse, these simultaneous improvements in battery size and device thinness will be made possible through new battery technology. While the specific technology wasn’t identified, previous industry rumors point to Samsung potentially adopting silicon-carbon battery technology.
Silicon-Carbon Battery Advantages
Silicon-carbon batteries represent a significant advancement in energy storage technology. These batteries offer several key benefits:
- Higher Energy Density : More power can be stored in a smaller physical space
- Compact Design : Allows for larger capacity batteries in thinner devices
- Industry Adoption : Already being used by Chinese manufacturers like Xiaomi, VIVO, and ZTE in devices featuring 6,000-7,000 mAh batteries
If Samsung adopts this technology for the Galaxy S26 Edge, users could see dramatically improved battery life despite the device’s ultra-thin profile.
Competitive Landscape
The timing of these improvements coincides with Apple’s expected release of the iPhone 17 Air, rumored to measure just 5.5mm thick but with a reportedly disappointing 2,900 mAh battery. Samsung’s approach of combining ultra-thin design with enhanced battery capacity could give the Galaxy S26 Edge a significant competitive advantage in the premium smartphone market.
Market Implications
These rumored improvements suggest Samsung is positioning the Edge series as its flagship ultra-premium offering. By potentially replacing the traditional “Plus” model with enhanced Edge variants, Samsung could simplify its product lineup while delivering cutting-edge technology that appeals to consumers seeking both style and substance in their smartphones.
The combination of larger batteries, slimmer designs, and advanced battery technology could establish the Galaxy S26 Edge as a landmark device in Samsung’s smartphone evolution, potentially influencing industry trends toward more efficient, thinner premium devices.
