I disabled Widget Locker this morning, haven't checked my battery or user stats yet but can confirm the occasional lag, Auto Bright app being quirky, and a few other weird things have stopped.
Fwiw, I have an extended battery because I prefer the in hand feel . On days I'm going to be away from electricity for a long time I carry a Newtrent 5200mah external battery to put a charge on if needed. It's about half the size of the phone and will charge the extended battery almost twice . Basically if I leave home with a full battery I have almost 3 batteries worth of charge using the external battery.
I'll keep checking apps and stats but I've disabled maps for now and my weather apps are working just fine without it.
