I think the main improvement in BLE was about security. What does that have to do with energy usage? Well, after some initial setup BLE allows devices to wake up and send data without a lengthy and expensive cryptographic handshake. Obviously this may not work as well if data is constantly being transmitted. This report tries to figure out approximately where that threshold is.
