Thanks to everyone. I've got a Sprint TP, using Verizon service and Verizon ROM, so that may be the issue. There is another thread stared today, with this issue, and some think culprit is provider data connection stopping, with phone then reaching out for wifi to get to data. I've got Activesync running with Exchange server, so constant polling for server sync.

I use WMwifirouter, but not running in the background--only have it open when I have a need for it.

Not using Fring (don't know what it is--need to check this out).

The Select Network tab states "Verizon Wireless", which should correctly refer only to my VZW data connection.

I'm usually able to head off the battery drain, when I get the 'ppiinng' sound of the Wifi picking up a network (and then go and manually turn off wifi).

Thanks for ideas.
