This is a typical result of failed upgrades: You have told the modem to
use the VERIZON 02.24.05.06 firmware, but this version is not yet
installed.

I don't know why your firmware upgrades fail, but fixing the low power
issue by switching to one of the installed images is easy:

 AT!ENTERCND="A710"
 AT!IMPREF="GENERIC"
 AT!RESET

or maybe you want

 AT!IMPREF="VERIZON"

instead? Not sure how that will work out, but I see that you do have a
02.05.07.00 verizon image installed.

You can list the same in the AT command interface:

AT!IMAGE?

Or maybe AT!GOBIIMAGE? Some firmware versions use AT!GOBIIMPREF and
AT!GOBIIMAGE, as well as the GOBIIM flag.  I believe newer firmwares
prefer AT!IMPREF and AT!IMAGE, and use the IMSWITCH flag.  The meaning
is the same.  Whatever works is fine.
