Chips Part 5: Big and little cores — how your phone saves battery
Phone chips mix a few big fast cores for heavy work with small efficient cores for light work, so everyday tasks use far less power.
Why does your phone have two kinds of cores? 📱⚡ Here's the trick 👇
1️⃣ BIG vs little: big cores are fast but use a lot of power. Little cores are slower, but they just sip power.
2️⃣ EVERYDAY WORK: music, messages, scrolling — the little cores handle it, while the big cores sleep. That saves a lot of battery.
3️⃣ HEAVY WORK: open a game or the camera, and the big cores wake up in milliseconds, do the hard work fast, then go back to sleep. Your phone picks the right core for you, all day long.
Big for speed, little for battery!
