Samsung is working on new battery tech, very slowly and carefully

Although Samsung appears to be trying out new things, battery technology is one area in which the company hasn't made significant progress in recent years. At least, that's what we see from the consumer side.

However, Samsung is reportedly testing new battery technologies behind closed doors. The company is on the fence and very prudent, but progress is being made somewhere in Samsung's laboratories.

Samsung is reportedly testing “lots of battery technologies,” according to @PandaFlashPro. The goal for Samsung is to develop a good battery with longer battery life, but safety is also one of the company's main priorities.

The company is taking a longer and safer road toward battery development. As per the recent rumor, Samsung won't release any new battery technologies until it is fully satisfied with the results. And to achieve the best results, Samsung has to perform long-term testing.

This safe approach could be why Samsung hasn't yet employed silicon carbon battery technology for any mobile device, including the Galaxy S25 Edge. In essence, a silicon carbon battery is based on lithium-ion but replaces the graphite anode with a silicon carbon one.

Although this battery type provides a higher energy density in a smaller package, it has its downsides. For one, the silicon carbon anode poses long-term durability issues due to volume expansion during recharge cycles.

Samsung values long-term durability now more than ever. The company offers extended firmware support for many products, including TVs and mobile devices. And batteries that degrade faster might go against the company's current philosophy.

Samsung might also be extra careful about adopting new battery technologies because of the issues it faced in the past. We need not remind anyone of the Galaxy Note 7 debacle, but it's safe to say that Samsung doesn't want or need another battery disaster on its hands.

All in all, the good news is that the company appears to be working on new technologies, and it is trying to get things right. But the cost of this approach might be slower progress toward meaningful technological advancements, at least as far as batteries are concerned.
