Apps Energy Used Android Calculator Formula and Mathematical Explanation
The calculation for an apps energy used Android calculator involves estimating the energy consumed by various hardware components that an app utilizes. The total daily energy consumption (in mAh/day) is the sum of the energy consumed by the CPU, screen, network, and GPS, each calculated based on its usage time or data volume and an assumed power rate.
Step-by-Step Derivation:
- CPU Energy (mAh/day): This component accounts for the processing power an app demands.
CPU Energy = (CPU Usage % / 100) * App Usage Time (hours/day) * CPU_POWER_RATE (mAh/hour)
The `CPU_POWER_RATE` is an estimated constant representing the average current drawn by the CPU when actively processing for an app. - Screen Energy (mAh/day): The screen is often the most power-hungry component.
Screen Energy = Screen On Time (hours/day) * SCREEN_POWER_RATE (mAh/hour)
`SCREEN_POWER_RATE` is an estimated constant for the average current drawn by the screen when active. - Network Energy (mAh/day): Data transfer, whether Wi-Fi or mobile data, consumes significant power.
Network Energy = Network Data (MB/day) * NETWORK_POWER_RATE (mAh/MB)
`NETWORK_POWER_RATE` is an estimated constant for the current drawn per megabyte of data transferred. - GPS Energy (mAh/day): Location services, especially GPS, are known power drains.
GPS Energy = GPS Usage Time (hours/day) * GPS_POWER_RATE (mAh/hour)
`GPS_POWER_RATE` is an estimated constant for the current drawn when GPS is actively used. - Total Energy Consumption (mAh/day):
Total Energy = CPU Energy + Screen Energy + Network Energy + GPS Energy - Battery Drain Percentage (%): To put the total energy into context, it’s compared against the device’s total battery capacity.
Battery Drain % = (Total Energy (mAh/day) / Device Battery Capacity (mAh)) * 100
