Plausible

For the past six years, Samsung has retained the battery capacity of its Galaxy S lineup at 5,000mAh, meaning that users would only experience minor increments in runtimes regardless of which company flagship they purchased. Fortunately, this practice could be a thing of the past, as a rumor claims that the Korean giant is finally jumping onto the silicon-carbon bandwagon like a multitude of Chinese smartphone makers.

As for why silicon-carbon batteries didn’t debut with the Galaxy S26 series, Samsung’s executive says these cells have to pass ‘very rigorous validation standards.’

The advantages of silicon-carbon technology are apparent, which is why Samsung and Apple have been rumored to be exploring these batteries, though no concrete launch timeline was mentioned. Since Chinese manufacturers have been sourcing these cells for a couple of years, the glaring question that needs to be asked is, why hasn’t Samsung adopted them? The company’s Executive VP and Head of Smartphone R&D team, Sung-Hoon Moon, spoke at the Galaxy Unpacked event, stating that the firm has been ‘a bit un-innovative on that front.’

It is no secret that Samsung continues to take a conservative approach with its flagship handsets, which is a strategy that has cost the company dearly. However, the firm simply cannot gravitate to silicon-carbon technology because these have to pass ‘very rigorous validation standards.’ Sung-Hoon Moon also mentions that customer experience is a top priority for Samsung, and once it believes that silicon-carbon elevates that experience, it will consider this option.

Prior to the Galaxy S26, a rumor doing the rounds claimed that the company was exploring a battery upgrade for the top-end model that would increase the capacity to a whopping 7,000mAh. Unfortunately, this rumor was quickly buried, and since then, we’ve only come across remnants of these claims, such as testing a 20,000mAh cell, then quickly abandoning this experiment. Perhaps one of the biggest reasons why Samsung isn’t willing to take a gamble is because it doesn’t want a repeat of the Galaxy Note 7 scandal.

Also, since the Korean technology behemoth ships more flagship smartphone units than Chinese competitors, there’s a small chance that defective silicon-carbon batteries are found in a few batches that cause them to catch fire or explode, which would turn into a PR nightmare for Samsung.
