Recently, it has been reported that Samsung is developing a new technology that is expected to increase battery capacity and charge faster.
According to TheElec, Samsung plans to introduce a new battery packaging technology called SUS CAN (Steel Use Stainless Can) in future mobile phones. The technology is a battery design with a stainless steel case, rather than the silicon carbon (SiC) solution commonly used in domestic mobile phones. It is said that it can not only improve the battery energy density and charging efficiency, but also effectively prevent the problem of battery expansion due to years of use. The larger the battery capacity, the longer the battery life and the faster charging makes daily use more convenient.
In fact, Apple has already adopted SUS CAN technology for the iPhone 16 Pro Max, leading the way. Samsung's follow-up is now seen as an important step to regain its advantage in battery experience. Although stainless steel is not as thermally conductive as aluminum, it has good strength and corrosion resistance, and it is also easy to replace the battery.
This is becoming more and more important for manufacturers. Especially after the new EU regulations come into effect, big brands will need to improve the repairability of their devices or face compliance pressure. If Samsung phones can achieve more durable and repairable battery designs with SUS CAN technology in the future, it will definitely be a big plus.
It is not yet clear which products Samsung will apply this technology to first. However, there are reports that the Galaxy S26 series, expected to be released next year, may be equipped with this new technology, and the Galaxy S26 Ultra may be equipped with a large-capacity battery of up to 5500mAh.
