I think you mean do not use and charge the device at the same time... maybe having the USB power connected and using the modem at the same time can cause the device to overheat? But is it really necessary to let the battery drain completely? Anyway, if you are correct, then the solution could be to set a timer on the USB…

Same problem here, turned off unexpectedly after 48 hrs while plugged in to a USB charger I was able to to restart it with some tinkering which included unplugging the USB power cable but now I have a problem because it was meant to run unattended 24/7... I wonder if the cause of the shutdown is overheating, and if that…
