Donut Labs has introduced a solid-state battery that can potentially revolutionize technology as we know it. Meanwhile, Samsung works on its iteration of solid-state batteries, planning to incorporate this technology into wearables by 2026. In the meantime, Chinese manufacturers are pushing the boundaries with batteries boasting capacities of up to 10,000 mAh.

Apple's Secretive Battery Development

etnews has cited industry insiders indicating that Apple is prioritizing numerous innovations for the next iPhone, including a new battery and enhanced camera technology.

“Apple has always prioritized quality and user experience over being the industry pioneer,” one source remarked. “With the upcoming 20th-anniversary model, we anticipate bold introductions of new technologies, akin to the iPhone X.”

Pure Silicon Battery: A Leap Forward?

Recent patents hint at the potential for pure silicon batteries to reshape our expectations of mobile devices. One such patent, aptly called "Interconnected Silicon Porous Structure for Anode Active Material," details a complex structure designed for enhanced performance.

Experts suggest that Apple's metal can technology could facilitate the integration of silicon in batteries, pushing performance boundaries to new heights. This combination of patents looks promising for the upcoming iPhone 18.

Potential Battery Capacity Estimates for iPhone 18

Current models, like the iPhone 17 Pro Max, feature a 5088 mAh lithium-ion battery. If the iPhone 18 Pro Max retains a similar size while incorporating silicon-based technology, we might see a 20% capacity increase, leading to an impressive battery performance.

While the advancements may not redefine the smartphone landscape, they pave the way for Apple to gain experience with cutting-edge technology in the battery arena.
