I really wonder what is the issue causing this. I bought two wakemates, one for myself and one for my mom as I'm home for the holidays, and for the past 3 nights each unit has functioned perfectly. As the package instructions say, before using them the first night we let them charge overnight for a full night because it said to charge fully before using the first time. The first two nights of usage we didn't charge the bands at all and they worked fine. After that we left them connected to the wall chargers all day, and they worked fine last night.

iPod touch and iphone here, but if the devices don't even talk to the phone during the night, I don't see how that variable makes a difference.
