Energy estimate value

The energy estimate values range from 5 to 9. The values are relative and cannot be converted into exact energy consumption values. The same energy estimate can mean different energy consumption levels in different networks, but it is comparable in a network when the network configuration stays the same.

The actual energy consumption per energy estimate value depends on the network. Operators configure differently the parameters that the networks use in data transmission, for example in repetitions, resource allocation, Discontinuous Reception (DRX), and connection release. Network parameters that are not known to the device can lead to different current consumption averages and connection durations in different networks. Therefore, it is not possible to calculate how much energy is going to be drained from the battery in an upcoming data connection based on the energy estimate value alone.

The energy estimate value is based on the current radio conditions. Because radio conditions can change rapidly in mobility use cases, the energy estimate depicts the following data connection most accurately in static or slow-moving mobility, such as pedestrian, use cases.

The energy estimate values have the following definitions:

Estimated energy efficiency of data transmission in different radio conditions. A higher value means better energy efficiency.
5 – Bad conditions. Difficulties in setting up connections. Maximum number of repetitions might be needed for data.
6 – Poor conditions. Setting up a connection might require retries and a higher number of repetitions for data.
7 – Normal conditions for cellular Internet of Things (IoT) device. No repetitions for data or only a few repetitions in the worst case.
8 – Good conditions. Possibly very good conditions for small amounts of data.
9 – Excellent conditions. Efficient data transfer estimated also for larger amounts of data.
