After being unplugged for 12 hours, MY phone is at 60%. As I've said before but you're too busy filling your diaper and being a shrieking ninny, while there may be a problem with YOUR phone, it's wrong for you to universally denounce the GS2 as defective. People might be more interested in helping you troubleshoot if you weren't such an obnoxious troll and emo crybaby. I'm pretty sure most forum members here would rather you go get an iPhone and depart these precincts.
Also, your "proof" shows that Facebook is a leading power hog and that you're battery is warm and your phone has been awake and on. That means you're clearly using it, but we can't tell what your brightness is set at and if you're using a demanding app, like a game, though it doesn't appear you are. Your telephone signal is weak as shown by the washed out yellow, so apps could be polling in vain. That's what I've seen before.
Either switch to decaf and get over yourself or get lost. I had a problem with my EVO having lack of memory space after GB and ran a thread collaborating with others for four months before giving up. Some people were reporting no problems whatsoever and others were in the same boat. By not going on a jihad attacking everyone who refused to chirp along with your pitiful bleats slamming the phone in toto, I was able to get advice and provide feedback in hopes of both solving my problem AND helping others with similar issues. It drives me nuts Googling for a tech problem fix to see others with the exact same problem, but never getting an answer or, even worse, posting, "I fixed it," without explaining what they did. What are you hoping to accomplish here other than being a big baby? You don't appear to be seeking help but are seeking others to agree with your specious point.
