Samsung is working to extend the Galaxy S26 series' battery life. The company is reportedly investigating modern "battery protection circuits" that will control the charge flow and stop batteries from overcharging or discharging too soon.
Epoxy moulding compound (EMC), a unique polymeric substance used in this technology, dissipates heat produced during charging or discharging, blocks moisture, and inhibits electromagnetic interference.
Samsung wants to extend the Galaxy S26 series' battery life by controlling heat and avoiding overcharging.
Since too much heat can accelerate battery degradation, EMC technology is necessary.
To create these battery protection circuits, the company has teamed up with ITM Semiconductor Co.
One advantage of this technology is that it makes room inside the phone for a larger battery pack by enabling smaller protection circuits.
According to rumours, the Galaxy S26 Ultra may have a larger battery of up to 5,500 mAh, which would be 10% more than the previous model.
Additionally, Samsung intends to change the batteries' casing to stainless steel or "SUS CAN" in order to potentially increase capacity.
Interestingly, the tech giant has chosen not to use silicon-carbon batteries, which have a higher charge density and can last longer without growing in size.
This technology has already been embraced by other phone manufacturers, including OnePlus and Nothing.
Nevertheless, faster charging on the Galaxy S26 series may be possible due to the enhanced security features, which would significantly impact the user experience overall.
