Tackle unexpected power drainage in deployed IoT devices by first analyzing power consumption patterns to pinpoint abnormal usage. Conduct thorough diagnostics on hardware and software components to identify inefficiencies, such as faulty circuits, firmware bugs, or misconfigured settings. Optimize power management by adjusting duty cycles, reducing active states, or enabling energy-efficient modes. Engage your team to brainstorm solutions and run field tests to verify improvements. Implement robust monitoring systems to proactively detect and prevent similar issues in the future.

🔸Optimize Power Settings: Use deep sleep modes and efficient wake-up triggers. 🔸Review Software: Debug and refactor code to eliminate energy-intensive processes. 🔸Use Low-Power Hardware: Switch to energy-efficient components and sensors. 🔸Minimize Data Transmission: Reduce frequency and size of data packets. 🔸Monitor Battery Health: Regularly check for degradation or inefficiencies. 🔸Implement Adaptive Scheduling: Dynamically adjust operations based on device activity levels.

One time, it happened to me when I was developing an IoT sensor board. One comparator IC consumed unexpected power; it was a tiny nanopower IC. Maybe during assembly, the IC got damaged and consumed more power. After inspecting the sensor, I desoldered the IC, and the power consumption returned to the expected nanoamp level. In the next version, to identify such problems very quickly, I added ICT to all functional and power pins. Effectively, by designing a test fixture for this particular sensor, I was able to identify such problems at the testing stage, whether the issue occurred during assembly or in PCB manufacturing.

1. Investigation and Analysis: Identify Affected Devices and Scope: Determine which devices are experiencing power drainage and the extent of the problem. Are all devices affected, or are there specific models or deployments? Data Collection: Gather data on power consumption, battery levels, operating conditions, and usage patterns of the affected devices. This can involve monitoring logs, sensor readings, and network activity. Root Cause Analysis: Analyze the collected data to pinpoint the root cause of the power drainage. Possible causes include: Hardware Issues: Faulty components, battery degradation, or power management circuits.
