BRN404X with device OS 6.2.1 & 5.5.0 - 8X and highly fluctuation power consumption

[jgskarda]

Good stuff... I'll give earlier device OS versions a try as well. Do you try each device OS down to OS 5.3.1. or just tested Device OS 5.0.0?

That said, I was hoping this could be fixed at device OS 5.5.0 as there was a pretty significant improvement in device OS 5.5.0 regarding this:

Enables UPSV=1 low power mode for R510 when idle for >=9.2s

I called out that change in this post:

BRN404 vs BRN404X - 2.4X increase in power consumption?

Yes, that is the power saving change that did not require enabling the full eDRX mode. It does not significantly affect power usage when transmitting and receiving, however it does reduce it when idle, and in sleep with network standby modes. The power usage should be lower with Device OS 5.5.0 or later and the R510 modem than it is with the R410. In network standby mode, the R510 usage is half to a third of the R410. The power improvement is 5.5.0 only for the R510.

I wonder if that UPSV=1 low power mode for R510 is affecting this somehow?

I guess in the interim, 30 mA is much better than nearly 80 mA! Would love to get back to 9 mA range though.

Sounds like we are making progress on learning more about this. Much appreciated!
