Just so you guys know, the Dev of WidgetLocker replied to the Motorola Forum
I have received several emails from people on this forum.
WidgetLocker actually never holds a wakelock for longer than ~5 seconds. However it's possible MotoBlur is holding excessive wakelocks when the lockscreen is replaced or something. If I can figure out where it's doing this I can try to work around it.
I have some users trying a beta of WidgetLocker and looking at logs. I also am trying to get my hands on a Photon.
If you want to help sending a bug report via Settings > Report Bug and simply putting "Photon battery issue" at the beginning of the body of the message will let me look for a pattern in WL or system configuration. Please don't expect a reply via email though as I might get several and will have nothing to report until right away.
PS The registration process for this forum is horrible.
