The power meter battery level graph allows you to track the battery level and usage of each power meter used in your training. The data points are taken from ride files uploaded to your account. Not all ride files, however, will contain the sensor information required to populate the graph. Power meter battery level may be included in .FIT and .RDE format rides. If you are not seeing any values recorded here, please contact customer support with information regarding your head unit type and manufacturer, as well as power meter brand and other supporting information. 

Most head units will prompt you with a low battery warning at 5% remaining, while the power meter battery battery graph can be used to give more advanced notice of low battery life before an upcoming long ride or multi-day event. Keep in mind that the battery voltage tracking does not take into account events that are not recorded within your activity files, such as rides that are not recorded or time in transit where the power meter may be activated by movement, but not being ridden. This graph is also not able to adjust for erroneous values reported by the head unit or values skewed by extreme hot or cold temperatures, which can result in lower values that return to normal range once they are used in normal operating temperatures. 

How to read the graph

The graph displays the average voltage or battery percentage (or both, if available) over time, as well as the min/max values for each time period. The graph will be broken down into weeks or months, depending on the amount of data available. Hover your mouse over each data point to see the min, max, and average battery values.  Your head unit may log battery values in voltage or percentage, depending on whether an ANT+ or Bluetooth connection is utilized. If both are used at times, both values may be seen on the graph.  Each item on the graph is labeled below the graph and clicking the name of each item will toggle it on or off.
