Sorry, missed this...

I'm definitely getting into sleep mode (according to the status LED), but it "feels" like something isn't being completely turned off.

If I use GPS and then turn it off (via Settings or the toggle widget) the battery seems to die quicker (even after a full recharge) until I reboot the phone.

I've worked on ultra low power electronics in the past (solar powered), so I know it can be something as silly as an output pin left in the wrong state that's leaking current into a part of the circuit that should be "off".


EDIT: Just as a quick test, I turned GPS on briefly (about one minute) and then turned it back off (no location lock). We'll see where my battery life goes throughout the day, but I should (according to prior data) be able to run ~ 20 more hours from now.
