// LESSON NOTES

Myth or fact: dark mode saves battery on EVERY phone? 🌙📱

✅ OLED screens: every pixel makes its own light, so black pixels switch OFF — dark mode helps.
❌ LCD screens: one backlight shines behind everything and stays on — dark mode saves almost nothing.
💡 On OLED, how much? A lot at full brightness (up to about 40 %), but indoors at normal brightness only a few percent.
⚖️ Verdict: HALF TRUE — not on every phone.
