Samsung Galaxy S26 Edge to pack a larger battery and slimmer profile than the S25 Edge

Samsung joined the slim-phone trend this year with its Galaxy S25 Edge. While the phone did not replace any of the models in the Galaxy S25 lineup, it was introduced as a new family member to the series. However, rumors suggest that Samsung could kill the "Plus" model from the lineup and replace it with the "Edge" model.

This year's Galaxy S25 Edge is thin, measures just 5.8mm, comes with a 200MP primary camera, and a 3,900 mAh battery. But now, it appears that Samsung is going to make the Edge model more exciting, as, according to a fresh leak by prominent leaker IceUniverse, next year's Galaxy S26 Edge is going to be a device to look forward to.

Firstly, the Galaxy S26 Edge will pack a larger battery compared to the Galaxy S25 Edge. Unfortunately, the leaker did not give any numbers. Secondly, the S26 Edge will shed even more thickness and be slimmer compared to the Galaxy S25 Edge. Again, no specific details, but could come close to 5.5mm (or even slimmer). Apple is expected to introduce its slim iPhone, the iPhone 17 Air, this year. It is expected to measure just 5.5mm thick but come with a disappointing 2,900 mAh battery.

IceUniverse says that the larger battery size and slimmer profile will come thanks to the new battery technology. Although the leaker did not specify which technology, earlier rumors suggest Samsung may adopt silicon-carbon batteries that will help the company fit bigger batteries inside the Galaxy S26 lineup.

Silicon-carbon batteries are more compact and allow for higher energy storage. Chinese OEMs like Xiaomi, VIVO and ZTE are already using this technology and offering phones with batteries ranging between 6,000-7,000 mAh. Also, if Samsung jumps to silicon-carbon batteries, you can expect a really big battery inside the ultra-slim Galaxy S26 Edge.
