Why do apps have dark mode?
Show answer & explanation
Answer: Reduce eye strain and battery use
Make text larger — Wrong. Dark mode doesn't change text size—it inverts colors (dark background, light text). Purpose is comfort and battery efficiency.
Use less data — Wrong. Dark mode doesn't affect data usage—it's a display setting. Benefits are reduced eye strain and battery savings on OLED/AMOLED screens.
Reduce eye strain and battery use ✓ — Correct! Dark mode benefits: (1) Reduced eye strain—especially low-light environments; less blue light emission. (2) Battery savings—OLED/AMOLED screens turn off black pixels (unlike LCD). Dark mode = more black pixels = less power. (3) Aesthetic preference—some find it easier to read. Circadian rhythm considerations—less blue light at night may improve sleep. Personal preference varies!
