Neben Stromsparmaßnahmen für die MicroPython-Firmware im Batteriebetrieb sowie LTE-Modem des Pycom FiPy komplett stilllegen gibt es noch ein paar andere Möglichkeiten.
Strom sparen mit Expansion Board
2018
Since you are using a regular expansion board, the flow control lines can interfere with the communication between the FiPy and the cellular modem. Can you remove the
RTSandCTSjumpers on expansion board and run your tests again?
Remove the RTS, CTS and LED jumper as suggested in other post.

I have the GPy on the Expansion board (v2.1) and the LED, RTS and CTS jumpers are removed.

Power consumption of the USB/UART bridge
Connecting over USB you’ll see an added, constant, power consumption from the USB-Serial chip (Expansion 2) or PIC micro (Expansion 3) as well as the USB LED.
I now see a substantial drop in current after powering the device through the VIN. Thanks!
The current went down to 11mA, which is just the power consumption of the USB/UART bridge.

When I start my program I first turn off all unwanted radios (current drawn with LTE, Bluetooth etc on is around 260 mA). When they are turned off the idle (no radios) current is around 65-70 mA, which correlates good with whats written in the specs for FiPY.

Diese Diskussion zwischen v.a. Daniel Campora und Robert ist hochinterssant, v.a. wird hier mal richtig gemessen.

Hier geht es auch aktuell wieder im Pycom-Forum um ähnliche Dinge bzgl. Stromverbrauch.
