The metrics in this chart come from the
power supply driver in the kernel.
- Energy Start
- The amount of energy in mW the battery contained.
- Energy Used
- This is difference between the "energy_now" measurements at the
start and end of the test. It represents the actual energy
that was consumed.
- Computed Energy
- We can multiple the "charge used" by an estimate of the
voltage:
end_voltage + 0.5 * abs(start_voltage - end_voltage)
to make a sanity check on the "energy used" metric. If this
value has a >1% difference, then we mark it so you'll know
something is inconsistent.
- Charge Start
- The amount of charge (in mA) reported by the battery at the
beginning of the test.
- Charge Used
- The difference of the "charge_now" metric at the start and end
the test.
