Samsung is still uncomfortable with the prospect of switching to silicon-carbon battery technology for the Galaxy S27 Ultra, but its hesitance has more to do with increased manufacturing costs rather than the uncertainty of the batteries themselves. Thankfully, a new rumor claims that the Korean giant is evaluating a higher capacity for its top-tier flagship, and hopefully, it will end up competing with the iPhone 18 Pro Max.
Moving to high-density silicon-carbon battery technology for the Galaxy S27 Ultra could incur an additional $22-$28 million cost
At present, @phonefuturist has discussed on Telegram that the reason Samsung steers clear of silicon-carbon batteries, at least for now, is that they cost between $22-$28 billion per one million Galaxy S27 Ultra units, as opposed to a cost of $12-$15 million for procuring lithium-ion cells for the same shipment tally. In light of the DRAM shortage, Samsung will do whatever it can to avert any unnecessary cost bumps, but that doesn’t mean the Korean giant isn’t testing out higher capacities for the Galaxy S27 Ultra.
A post on X reveals that the company is currently evaluating a cell in the 5,600mAh-5,800mAh range, which is smaller than what Chinese smartphone makers have adopted in their flagships, but paper specifications only provide half the truth. Additional details from the post mention that the Galaxy S27 Ultra could feature a minimum capacity of 5,500mAh if testing goes successfully, marking the first time that Samsung has gone beyond the 5,000mAh threshold since the Galaxy S20 Ultra’s inception.
Then again, if Apple’s iPhone 18 Pro and iPhone 18 Pro Max can feature bigger batteries, there’s no reason why Samsung has to keep making excuses in this area. Just like how the iPhone 17 Pro Max manages to deliver record battery life through optimizations, Samsung can use this opportunity to obtain a foothold against its competitors by tweaking its OneUI to sip less juice during certain activities.
Also, given that the Galaxy S27 Pro is rumored to arrive with a 5,000mAh battery, which is the same capacity as the Galaxy S26 Ultra, Samsung certainly doesn’t want buyers to have one more reason to skip the Galaxy S27 Ultra, especially during the memory crisis, which threatens to reduce smartphone demand substantially. We’ll also advise readers to treat this information with a pinch of salt, and we’ll return with more updates.
