I'm on Cyanogenmod 11 Snapshot M5 and I have recently have had this issue with my battery where it would drain fairly quickly throughout the day and after I put the charger in, after a couple of minutes it's at 50 or so percent? So how does the phone die if there is actually some juice in the battery? Help would be appreciated, thanks in advance.

:what: yes mines died and when I plugged it up to the wall charger it displayed 85%. Can you say freaky
