I upgraded to ios4 on Monday, everything seems to be working fine aside from the fact everyone with a 2nd gen got left in the dust when it comes to features. One problem I have been noticing is my ipod's battery seems to be draining much faster when I'm not using it then before. I'll leave it unplug and un-used over night with a full charge and when I wake up it'll be sitting at almost %50 life. So what gives? Why am I loosing so much of a charge when I let my ipod sit for a while? Has anyone else had this problem? thanks!
