I've used a Weather demo to measure battery usage by device. Even if I switch backlight off it only lasts for 2-3 hours (with active BLE connection).
I'm now trying to increase reporting interval from 1 to 10 seconds to reduce energy consumption.
Is it really the case that I can't really switch sensors off.(using IoT Studio) and it only possible to switch data reporting off?
What other options should I consider to reduce its power budget?
