Well, the battery issue has been a D4 problem since day one. It's been significantly better since I've used custom ROMs (Eclipse and Liquid), mostly due to the removal of VZW bloatware. You can also make lots of changes to make the battery last longer. Everything else leads me to believe you got a bum phone. Capitalizing the first letter is a default of the stock ROM I believe, and can be set in Languages and Input. I've never dropped a call because of any notifications. I would definitely go to Verizon and get a warranty replacement. I never felt the need to search the forums for these issues because I never came across them. I'm on them daily (well, this and XDA, but only for development) and have not seen anyone say anything bad about the JB OTA.
