Samsung has always been at the forefront of smartphone innovation, driving advancements in display technologies, RAM speeds, and more. However, when it comes to battery tech, the company is still sticking with the tried-and-true lithium-ion batteries. 
Even the latest Galaxy S25 Edge relies on this older technology, with no significant upgrades to energy density or charging speeds.
But that doesn’t mean Samsung isn’t working on improving its batteries. A recent insider report from PandaFlashPro reveals that the company is actively exploring new battery technologies behind the scenes.
Samsung’s Focus on Safety and Longevity
According to the report, Samsung is testing new battery chemistries to achieve better performance and longer battery life. However, the company is taking a cautious approach, prioritizing safety and lifespan over rushing to market with cutting-edge tech.
Samsung’s careful strategy might explain why silicon-carbon batteries won’t be featured in the upcoming Galaxy S25. While competitors like Xiaomi and OnePlus are already using silicon-carbon technology in their flagship phones, Samsung seems to be taking a more measured approach.
Why Samsung is Avoiding Silicon-Carbon Batteries
Silicon-carbon batteries have some notable drawbacks, particularly related to durability. The expansion of silicon during charging cycles can degrade the battery’s lifespan, which is counterproductive to Samsung’s current focus on long-term product reliability.
Samsung’s commitment to long-term reliability is why the company offers software updates for up to seven years on its flagship devices. To ensure that the batteries can last that long, Samsung is taking extra care to test any new tech thoroughly before integrating it into their devices.
The infamous Galaxy Note 7 battery incident still looms large in Samsung’s history, which likely explains why the company remains extra cautious about introducing new battery technologies, even if it means facing criticism for slow progress. Samsung’s focus on ensuring safety and reliability is evident, and it seems that it will only move to newer technologies once they can guarantee their products meet the highest standards of performance and longevity.
Interestingly, Samsung is reportedly planning to introduce silicon-carbon batteries in its first tri-foldable phone, which could mark the beginning of a shift toward more advanced battery tech in future devices.
