and for direct-to-satellite, it's going to be a max power
situation, similar to <br>
rural.<br>
<br>
But when a phone is not connected, how frequent are it's
searches for towers <br>
(especially if it has multiple bands to check) compared to the
'keepalive' pings <br>
when it is connected? if it's doing more transmissions for
it's search and <br>
attempts to connect than it does while connected and just
confirming the <br>
connection, that could eat more power.<br>
