How We Calculate Battery Runtime

  • Battery Health Model:
    • Li-ion: 0.04% capacity loss per full cycle (Apple/Samsung standards)
    • Li-polymer: 0.03% loss (better heat resistance)
    • Solid-state: 0.015% loss (experimental technology)
  • Power Consumption Formula:
    • Base = 100mA (system processes)
    • + Background apps (8mA per active app)
    • + Usage intensity (35mA per intensity level)
    • + Display (20mA per 60Hz increment)
    • + Network (25mA per generation: 4Gā†’5G)
  • Sleep/Wake Ratio:
    • Active mode: Full power consumption
    • Sleep mode: 20% of base consumption
  • OS Efficiency:
    • iOS: 15% more efficient than baseline
    • Android: Standard consumption
  • Refresh Rate: 90Hz displays consume 1.5Ɨ more power than 60Hz, while 120Hz uses 2Ɨ.
Note:.
  • Results assume room temperature (25Ā°C).
  • Cold weather (< 10Ā°C) may reduce runtime by 15-20%.
  • Heavy gaming can increase consumption by 300%.
iPhone Battery Usage Optimization Tips
  • Adjust Screen Brightness: Lower brightness levels significantly reduce battery consumption on iPhones.
  • Enable Low Power Mode: Activate this feature when battery is low to extend battery life.
  • Check Battery Health: Monitor your battery health percentage in Settings > Battery > Battery Health.
  • Disable Background App Refresh: Limit which apps can update content in the background under Settings > General.
  • Turn Off Unnecessary Location Services: Control which apps access your location under Settings > Privacy.
  • Use Wi-Fi Instead of Cellular Data: Wi-Fi connections typically consume less battery than cellular data.
  • Update to Latest iOS: Apple regularly improves battery optimization with iOS updates.
Android Battery Usage Optimization Tips
  • Use Dark Mode: Enables battery savings on OLED screens by reducing pixel illumination.
  • Activate Battery Saver Mode: Extends battery life by limiting background processes and notifications.
  • Restrict Background Battery Usage: Manage which apps can use battery in the background under Settings > Battery > Background restrictions.
  • Disable Always-On Display: Turn off this feature to preserve battery life throughout the day.
  • Optimize Auto-Sync Settings: Limit which apps automatically sync data in the background.
  • Manage Connectivity Features: Turn off Bluetooth, NFC, and location services when not in use.
  • Use Adaptive Battery: Let Android's AI learn your usage patterns to optimize battery consumption.
