|
||
|
|
|countdischarge |episodes | Number of discharging episodes.
|
||
|
|
|sumdurationdischarge |minutes | The total duration of all discharging episodes.
|
||
|
|
|countcharge |episodes | Number of battery charging episodes.
|
||
|
|
|sumdurationcharge |minutes | The total duration of all charging episodes.
|
||
|
|
|avgconsumptionrate |episodes/minutes | The average of all episodes' consumption rates. An episode's consumption rate is defined as the ratio between its battery delta and duration
|
||
|
|
|maxconsumptionrate |episodes/minutes | The highest of all episodes' consumption rates. An episode's consumption rate is defined as the ratio between its battery delta and duration

|
|
!!! note "Assumptions/Observations"
|
||
|
|
1. We convert battery data collected with iOS client v1 (autodetected because battery status `4` do not exist) to match Android battery format: we swap status `3` for `5` and `1` for `3`
|
||
|
|
2. We group battery data into discharge or charge episodes considering any contiguous rows with consecutive reductions or increases of the battery level if they are logged within `[EPISODE_THRESHOLD_BETWEEN_ROWS]` minutes from each other.
