Hi,
I am newbie of this site.I think With wifi on, cell radio, gps and bluetooth off, no notifications, no apps allowed to connect besides sipdroid, I get 30 hours standby on Captivate. Under the same conditions, I get over 250 hours with my iPhone 4...
This can't be a straight hardware issue, I'm at a loss to explain why android is unusable as a wifi-only softphone, while the i4 does the job perfectly.
Thanks!!
