I've noticed that when the setting for Handcent SMS has the Blinking LED to "Fast", "Normal", or "Slow" it'll eat up resources and takes up +80% of the Partial Wake Time Usage according to Spare Parts. I've noticed this with 2.1, 2.2, and 2.2 again after a hard reset. I'm assuming it's an issue with the last few updates of Handcent as I did not have this problem a month ago. With it set to "Default" blinking it'll consume normal resources like every other app. Thing is with the "Default" blinking, it just stays green like it's fully charged. I'd appreciate if someone else can look into this and see if this same issue is present for you.
