1. A method comprising:
- determining, via a device, whether a power level associated with the device is above a threshold or that a battery associated with the device is charging;
in response to determining whether the power level is above the threshold or that the battery is charging;
receiving, via the device, a plurality of calibration measurements associated with one or more sensors of the device;
determining, via the device, a degree of variance to which the plurality of calibration measurements were obtained at different orientations of the device; and
determining, via the device, based on the determined degree of variance, whether to update one or more calibration parameters, wherein the calibration parameters are used to calibrate the one or more sensors of the device.

Abstract
Aspects of the disclosure relate to computing technologies. In particular, aspects of the disclosure relate to mobile computing device technologies, such as systems, methods, apparatuses, and computer-readable media for improving calibration data by increasing the diversity of orientations used for generating the calibration data. In one embodiment, the computing device receives a plurality of calibration measurements associated with one or more sensors of a device, determines a degree to which the plurality of calibration measurements were captured at different orientations of the device, and determines, based on the degree, whether to update one or more calibration parameters.
