In recent years, Samsung has been criticized for not making any significant progress in battery technology and fast charging on Galaxy phones. However, it seems that the company is preparing to apply a completely new battery technology, which will help improve capacity and solve the problem of battery swelling after a period of use.

According to SamMobile, Samsung is planning to integrate new battery technology for future phone lines. However, this technology is not a Silicon Carbon battery, which many Chinese companies are testing, but SUS CAN battery technology, short for Steel Use Stainless.

SUS CAN battery uses a stainless steel shell instead of aluminum, helping to increase energy density, improve charging speed and especially prevent battery swelling, a problem that has appeared on many Galaxy phone models in the past. This technology has been used by Apple since the iPhone 16 Pro Max generation.

Although stainless steel does not have the ability to dissipate heat as well as aluminum, it is more durable and more resistant to corrosion. In addition, the battery design with a steel shell also makes the battery replacement process easier, in line with new regulations of the European Union requiring increased repairability and replacement of components on mobile devices.

It is still unclear when Samsung will officially bring this technology to Galaxy phones and tablets. However, the technology community expects the company to deploy it right from the Galaxy S26 line, which is expected to launch early next year. Some previous reports also said that the Galaxy S26 Ultra may have a battery capacity of up to 5,500mAh.

If this is true, this will be a breakthrough worth looking forward to, significantly improving the user experience and enhancing the durability of the device in the long term.
