Just ordered the iPhone 5 - should I load it up with iOS 7?

I have iOS 7 loaded up on my iPod touch and I noticed that there is a battery issue (yeah, it did improve with beta 3 but the issue is still apparent). Since my iPhone is going to be new I fear putting it through iOS 7 will abuse the battery life and make it shorter in the long run. Do you think that I should just wait for iOS 7 or do you think that the effects will be negligible in the long run?
