Does anyone have any input on the impact different wireless encryption
settings have on 7920 battery life?
I have a client that uses 128 bit WPA encryption on 7920s with the
cmterm_7920.4.0-03-02 firmware, and when the phones are up and
registered the battery lasts about 3 hrs when the phone is just
sitting there idle waiting for calls, etc.
I took another 7920 phone there, and it does the same thing. I had
left the site with a full charge on the 7920 and nearly 7 hours later
the phone still has one third of battery left but is not authenticated
to any wireless network and is sitting here trying to authenticate and
has been on since I left there so it doesn't appear to be a battery
issue but maybe something to do when it is up and running.
