2027 iPhone May Feature Game-Changing Silicon Battery Tech
Apple is reportedly looking into using pure silicon anode battery technology for its 2027 iPhone model, potentially delivering a dramatic leap in battery performance, according to a recent ETNews report citing Korean supply chain sources.
The technology would replace traditional graphite anodes with 100% silicon, which can theoretically store up to 10 times more lithium ions per gram than current materials. This could substantially increase the energy density of the battery without enlarging its physical footprint.
Apple would have to overcome some steep technical hurdles, though. Silicon anodes have a tendency to expand up to 300% during charging, causing structural degradation. Any breakthrough in the technology's development would first have to solve this basic problem.
If such a breakthrough were achieved, the new battery architecture could enable significantly longer battery life, faster charging speeds, and improved thermal efficiency in a device that's not necessarily thicker. If Apple perfected the technology, it would likely represent one of the biggest battery advancements in smartphones since the widespread adoption of lithium-ion batteries.
A silicon battery could form part of an ambitious redesign for the iPhone's 20th anniversary. Rumors suggest the 2027 Pro model could also feature a bezel-less display with four curved edges and under-display camera technology.
