Galaxy S26 Series: Enhanced Battery Protection for Faster Charging

Key Takeaways

1. Samsung is falling behind Chinese rivals like OnePlus and Vivo in battery capacity, with innovations allowing for over 6,000 mAh batteries.
2. Samsung is collaborating with ITM Semiconductor Co. to enhance battery life and protection in the upcoming Galaxy S26 series.
3. The Galaxy S26 is expected to feature upgraded battery protection circuits made from EMC to prevent overcharging and improve heat dissipation.
4. The Galaxy S26 Ultra is rumored to have a battery capacity of 5,400 mAh or 5,500 mAh, marking a 10% increase from the Galaxy S25 Ultra.
5. Samsung may upgrade to stainless steel battery housing and increase charging capabilities to 65W for the Galaxy S26 Ultra, compared to the current maximum of 45W.

When it comes to the battery capacities in top-tier smartphones, Samsung is lagging behind its Chinese rivals. Brands like OnePlus and Vivo have adopted innovative battery technologies that allow for capacities exceeding 6,000 mAh. Although the upcoming Galaxy S series might not feature this advanced tech, there are expectations for other enhancements related to battery protection.

Samsung’s Collaboration for Battery Improvements

A report from the Korean outlet The Elec (translated to English) reveals that Samsung is teaming up with South Korea’s ITM Semiconductor Co. to enhance battery life in the Galaxy S26 series. The base model, Galaxy S26, is set to receive upgraded battery protection circuits made from EMC, or epoxy molding compound. These improvements aim to prevent issues such as battery overcharging and rapid discharging, along with boosting heat dissipation.

Potential for Larger Batteries

In addition, these EMC-based circuits are designed to be smaller, which might theoretically allow for bigger batteries within the Galaxy S26 series. It remains unclear if Samsung will increase the battery size for its next flagship models. Interestingly, the Galaxy S26 Ultra is rumoured to feature a battery capacity of either 5,400 mAh or 5,500 mAh, depending on marketing strategies, representing a 10% increase compared to the current Galaxy S25 Ultra.

Material Upgrades and Charging Capabilities

The company is also anticipated to utilize stainless steel or SUS CAN battery housing for the new devices, which could support higher battery capacities. Meanwhile, Chinese smartphone makers have transitioned to Silicon Carbon batteries for their flagship models. A prime example is the OnePlus 13 (available on Amazon), which includes a dual-cell 6,000 mAh battery that can charge at a rapid 100W. In contrast, Samsung currently offers a maximum of 45W wired charging on the Galaxy S25 Ultra (also available on Amazon), but it may elevate the Galaxy S26 Ultra to support up to 65W wired charging.
