Wow, I went over that logcat you sent me. Your phone is CONSTANTLY working/running, which is weird and there are a ton of database errors.
You have a reoccurring database error "android.database.sqlite.SQLiteException" and the LG MLT app seems to be throwing some errors. What's concerning is NO ONE on the interwebs seems to know what this damn app does. It appears to be a system monitor app, so it *could* be frozen. But please note, I don't know if freezing that app will lead to other issues (like when you freeze 'messaging', you can't send mms); if you start to see adverse reactions, unfreeze it.
