In what seems to be a fresh Samsung Galaxy S26 rumor, the Galaxy S25's successor is reportedly being improved to accommodate the Silicon-Carbon (Si/C) battery technology that could help enhance its battery capacity.
This could be the South Korean giant's shot to allow Samsung Galaxy S26 to have it at 7,000 mAh.
Silicon-Carbon Battery Technology on Galaxy S26
Silicon-carbon batteries are a major breakthrough in mobile battery technology. Unlike traditional batteries that use graphite in the cathode material, Silicon-carbon batteries replace graphite with silicon.
This change significantly improves the battery's energy storage capacity, allowing manufacturers to fit higher capacity batteries into the same or even slimmer form factors, according to South Korean outlet FN News.
This may be the key to resolving the long-term issue of battery longevity in smartphones. Consumers will still want to see longer-lasting devices, and this innovation can finally deliver that promise without the need for a significant size or weight increase in the phone.
Why Samsung Is Considering Silicon-Carbon Batteries?
Samsung has its reasons for exploring Silicon-carbon batteries. As with all flagship models, the company is always innovating to produce better products that can keep the company ahead in the market by outperforming competitors such as Apple, Xiaomi, and OnePlus.
Although this new battery technology has been an issue for Samsung due to some production cost fears and material untrustworthiness, other manufacturers like Xiaomi, Vivo, and OnePlus have been quick to integrate Silicon-carbon batteries into some of their mobile phones. The success of these devices has likely pushed Samsung to follow suit.
One of the main reasons for Samsung's caution is its scale of production. The company manufactures far more units than its Chinese rivals, meaning any issues with the new battery technology could have widespread consequences. However, with more and more brands embracing the technology and addressing the challenges associated with it, Samsung seems ready to take the plunge with the Galaxy S26.
Overcoming the Challenges of Silicon-Carbon Batteries
There has been initial doubt about Silicon-carbon batteries mainly because of their high production cost and the problems related to material expansion. Nevertheless, improvements in battery technology are now overcoming the previous issues. The investments of Samsung in the research and development of Silicon-carbon batteries seem to be fruitful now.
It is said that the company is trying to resolve material composition problems so that it can enhance the performance of the battery without any loss of reliability.
In addition, the thinner Silicon-carbon battery might open doors for Apple to integrate the same technology into the future iPhone 17. Once Samsung perfects this technology on its devices, other tech companies will be influenced by this innovation and will most likely follow, making it a chain reaction in the mobile market.
How Silicon-Carbon Might Change Galaxy S26
The most visible benefit of adopting Silicon-carbon battery technology in the Galaxy S26 is the capability to pack more power into the device without adding to its physical size.
Rumors go around that this Galaxy S26 might get a humongous 7,000 mAh battery, far bigger than the 5,000 mAh battery that existed in the Galaxy S25 Ultra. In that case, the user could work on their devices for way longer periods without recharging constantly.
Moreover, this transition may also make it possible for Samsung to upgrade the fast-charging feature. The ones currently offered on the Galaxy S25 are 25W and 45W, and these might carry over into the Galaxy S26, but that increased power might provide a bigger battery capacity and thus shorten the time it takes to fully charge the device.
