Another metric that can help you evaluate the effectiveness of your MDM policies is the performance of your mobile devices. This includes aspects such as battery life, memory usage, network connectivity, app crashes, and device errors. These factors can affect the productivity, satisfaction, and security of your mobile users, and may indicate that your policies need to be adjusted or optimized. For example, if your devices are running out of battery quickly, you may need to review your power management policies and enable features such as low power mode or screen timeout. If your devices are experiencing frequent crashes or errors, you may need to update your software or firmware policies and ensure that your devices are running the latest versions. You can use your MDM tools or third-party solutions to collect and analyze the performance data of your devices and troubleshoot any problems.
