Smartphones equipped with the highest capacity silicon-carbon batteries today

The smartphone industry is witnessing a major shift with the adoption of silicon-carbon battery technology. This technology not only offers higher energy density, but also allows for faster charging speeds and improved durability. Compared to traditional lithium-ion batteries, silicon-carbon batteries offer greater capacity in a compact design, extending battery life without increasing the weight or thickness of the phone.

Several flagship smartphones launching in late 2024 and early 2025 will feature this advanced battery technology, which will bring significant improvements in power efficiency, thermal management, and charging cycles. Here are the five latest smartphones equipped with silicon-carbon batteries and their highlights:
