Gee whiz, sounds like the reviewer didn't turn off WiFi nor does not want to be bother to safe battery life.....
"The modem can be turned off with an external switch, and Amazon said that should allow the device to run for a week between charges. I didn't have the time to test this claim, but in any case, I don't want to be bothered with remembering to turn the modem on when it's time to download the day's newspaper, then turning it off."
I think flicking the switch to turn off the Wifi will go a long way to increase battery life. :-)
