When it comes to smartphones, we're basically living in two different worlds right now. On one side, you have brands like Samsung and Apple still sticking with lithium-ion batteries, while on the other, companies like Oppo, and Xiaomi have moved to silicon-carbon battery tech.
This change means that silicon-carbon batteries on these newer flagships are often around 25-35% larger than what traditional lithium-ion phones offer. Yet, brands like Apple and Samsung still claim "all-day battery life" in their presentations.
