Whose having battery issues at this point? Before the update I was good all day, now after the update I am living large sometime not charging her for almost 2 days its quite amazing, launch day evo too!
Just as a tip of what I do...
No task killer
Brightness setting down
Gps off
Bluetooth off, only on when needed driving
Timeout to 15s
No live wallpaper (not that it makes a diff)
Charge overnight
Use its moderate all day on and off
