I have had my thunderbolt since launch day and usually charge it overnight connected to my computer. I've been getting great battery life after running green power and most of my usage says its display. last night i used the wall charger for a change and today the battery was draining like mad and it said that the android system was taking 80% of my power over the whole day. Has anyone experienced this bug and have any ideas as to what could have caused the problem? I had no changes to settings other then the difference in where i charged it last night.
