I've noticed this odd quirk for a while, both before and after the big update in May. When the LCD shuts off, either due to locking it manually or simply letting the screen turn off through inactivity, it will "wake up" ever few minutes. It doesn't unlock, just shows the normal locked screen. It then usually fades and turns off again a short while later. It's like it has sleep apnea or something.

I'm worried this will drain the battery faster than staying off reliably. My best guess would be some program is doing this, but I'm not sure what. Anyone have any ideas?

Thanks,
