Most users believe:

  • “My phone is old — nothing can fix it”
  • “Installing cleaner apps will boost speed”
  • “Updates permanently slow down phones”
  • “More RAM apps = better performance”

✅ Reality

Slow Android phones are usually caused by:

  • Average user installs 30+ apps but uses only 8–10
  • Background apps consume up to 50% RAM silently
