I haven't seen this addressed in any of the awake time posts with the exception of one comment that the phone doesn't sleep while charging. Under Settings>Applications>Development I unchecked "Stay Awake" and found that the phone will sleep while charging. At 40 hours after reboot I'm at 9% wake time. Just thought I'd throw this out there.
this has been posted before a few times although it was not in a separate thread. my phone was out of the box set that way....
Odd, I have had Four Hero's now, and none of them had that feature enabled out of the box. Must be luck of the draw, or a problem with certain batches of them. Thanks for the info guys and I stand corrected.
I think someone mentioned here that if you have a Sprint store transfer your contacts to the hero, they make that change (check the box to stay awake)
