Samsung smartphones might soon fix the worst chink in their armor. According to the South Korean daily FN News, the company is mulling plans to fit next-gen silicon carbide batteries inside its upcoming Galaxy S26 series flagship smartphones. And it seems the Chaebol’s mobile division won’t be pulling any punches.

As per the report citing industry insiders, Samsung could offer a battery as large as 6,000-7,000 mAh in capacity with the upcoming Galaxy S26 series. For comparison, Samsung’s current top-tier offering, the Galaxy S25 Ultra, comes equipped with a 5,000mAh battery. The competition, however, is already offering batteries of up to 7,000mAh capacity at nearly half the sticker price of Samsung’s flagships.

The Korean electronics giant is reportedly keen on deriving benefits of the silicon carbide battery tech, which promises higher energy density, allowing brands to fit high-capacity batteries in smaller packages. Take for example the Red Magic 10 Pro, a phone that is nearly as big as the Galaxy S25 Ultra, but offers a 7,000 mAh battery with 100W fast charging chops.

Samsung, however, is concerned about the hit on battery longevity. To fix that conundrum, the company is reportedly planning to experiment with different material choices, and adjusting the percentage concentration of silicon in the battery anode to achieve a denser, longer-lasting battery.

Another advantage of silicon carbide batteries is that they don’t hamper the charging pace figures. For example, brands like OnePlus and Honor have already managed to fit massive batteries in their latest flagships while simultaneously offering charging rates north of 80W in wired mode.

To put that into perspective, Samsung’s current-gen phones only go up to 45W in wired mode, and far slower in wireless format. The OnePlus 13, on the other hand, allows 50W wireless charging, while Samsung’s best phones can only muster a peak top-up rate of 15W.

Now, the latest report emerging from Samsung’s home market isn’t a certainty that the Galaxy S26 series will finally put an end to arguably the weakest aspect of Samsung smartphones. The shift might take another year, or two, even. But it is definitely reassuring to see that Samsung is paying attention to practical innovations and might not remain a laggard for longer than it can afford to.

The company’s mobile division certainly appears to be chalking the right course lately. As per Counterpoint Research data, the Samsung Galaxy S24 Ultra marked the first time since 2018 that a Samsung Galaxy device has entered the top ten list of the world’s highest-selling smartphones each year.

Samsung promises not to remove S Pen from future Galaxy S Ultras
The Samsung Galaxy S25 Ultra and the S Pen Stylus.

The S Pen has become the top-tier accessory for people who like to draw and take notes on their phone, especially on the Samsung Galaxy S25 Ultra. However, the future of the stylus has become a topic of debate lately, as it wasn't included in the Samsung Galaxy Z Fold Special Edition package. Fortunately, the company promised not to leave out the S Pen from future Galaxy S Ultra models.

Annika Bizon, VP of Product and Marketing at Samsung's Mobile Experience in the UK, recently told TechRadar at MWC 2025 that Samsung Galaxy users don't need to worry about whether or not the S Pen will be included in future models. The stylus was left out of Samsung's Galaxy Unpacked event showcasing the Galaxy S25 series back in January, but just because it was absent from recent marketing campaigns for the latest model doesn't mean it won't be a part of the upcoming Galaxy S Ultra phones.

Samsung’s super-slim S25 Edge might come with a side of battery life struggles

Both Samsung and Apple are gearing up to release super-slim smartphone models this year. Rumors suggest that Apple is going for a high-density approach to pack in more power but a certification from Denmark shows the Samsung Galaxy S25 Edge does not have a similar trick up its sleeve.

Spotted by GSMArena, the certification reveals that the S25 Edge will use a battery with a capacity of 3,900 mAh -- that's 100 mAh less than the S25. While it makes sense that a smaller phone would have a smaller battery, Samsung could end up regretting this decision if the iPhone 17 Air's battery manages to be both small and high-capacity.
