My sensor's battery isn't holding charge.

We are sincerely sorry about the trouble you are having with your sensor's battery life.

Structure Sensor Pro and Structure Sensor (Mark II) should hold approximately 1 hour of charge. If you believe your sensor holds a much smaller charge, please perform a battery test by following these steps:

  1. Fully charge your sensor using the long, white charging cable and a sufficient power source. Your sensor will display a solid blue indicator light when fully charged.
  2. Plug your sensor into your iPad with the short, black lightning or USB-C cable.
  3. Launch the Structure app.
  4. Once your sensor initializes, tap the "i" icon in the upper right corner.
  5. Start a stopwatch.
  6. Keep the Structure app open for the full test.
  7. Once the sensor depletes and disconnect, stop the stopwatch and note the time.

Let us know the length of time to discharge, and we will be able to assist you with next steps.

We will also need to know your sensor's serial number to be able to check its warranty status. You can find it by referencing this article: Getting Started - How Do I Find My Sensor's Serial Number?
