How we calculate battery longevity

  • Base Lifespans:
    • Lithium-ion battery life expectancy: 5 years (avg. smartphone)
    • Li-polymer battery life expectancy: 6 years (common in phones with good battery life)
    • Solid-state battery life expectancy: 8 years (emerging tech for extended cycle lifetime)
  • Usage Impacts:
    • Heavy use reduces lifespan by 40% (gaming/5G drain cycles faster)
    • Optimal charging (20-80%) preserves 20% more cycle life
  • iPhone Battery Life Boost:
    • iOS devices show 10% longer lifespan vs. Android (hardware-software optimization)
  • Charging Habits:
    • Regular fast charging shortens lifespan by 6-18 months (heat stress)
iPhone: Check battery health and capacity
  1. Open Settings → Battery
  2. Tap Battery Health & Charging (iOS 16+)
  3. View Maximum Capacity (%) for lithium-ion battery life expectancy

💡 Pro Tip: iPhones with 80%+ capacity maintain good battery life. Use our battery longevity calculator to estimate remaining cycle lifetime.

Android: Monitor battery life and cycle count
  1. Open Settings → Battery or Device Care (Samsung)
  2. Check Battery Usage for app-specific drain
  3. Look for Battery Health (varies by brand) to see remaining capacity

💡 Pro Tip: Phones with good battery life (e.g., Pixel, Galaxy) often show cycle counts in diagnostic menus. Pair this data with our battery cycle life calculator for accurate predictions.
