Rumblings afoot that some have experienced battery times diminishing on the iPhone after upgrading to 4.1 and 4.1 GM. Assuming that the Gold Master is the same as the release (which it should be), curious to hear from those who have had enough experience to have formed an opinion. If it's too early to tell, please come back and take the poll when you do have an opinion. Given the less than stellar battery life on my iPhone 4, I'd hate to make it worse by upgrading, but I'd love to give HDR photography a go. Opinions?
