Is anyone else experiencing problems with their battery after the 4.0.4 update? I did the hard reset too which helped my battery now i'm back to 10-12 hours on a full charge when i use to get over a day for the same amount of usage. I'm also noticing a lag when i click on an application and then hit the home button it takes a second for the applications/time/weather to appear on the home screen... This has never happened...... Samsung is going to be loosing a customer if they don't fix this problem....
