Being able to early power profile your #cellular #IoT application is important to understand how long battery life you can expect out of the application. Using our Online Power Profiler on DevZone to estimate power consumption or the new Power Profiler Kit II (PPK2) to measure power consumption will make this a lot easier in your developing process.
