Cell on my phone contributes like less than 10% of total battery consumption. The most goes to screen and cpu. So there's limited improvement for 5G in this. But for IoT devices in which comms use most of the battery, this could be significant. However, it's debatable whether spending on billions of dollars on a regional 5g network is an optimal solution for a more durable IoT infrastructure. In my understanding, there should be a more economical way to build an efficient IoT infrastructure since most of them don't need that much data speed.
