iOS 7 it's been available for a month already and every person I've talked to about the new version of the operating system has complained about battery life. Although Apple Lossless Audio CODEC (ALAC), has already released an update for iOS that should have solved the initial problems encountered by many regarding battery autonomy, it seems that for now there are still dissatisfactions and they are not few. I can confirm that including iPhone 5S, which I restored as new especially to avoid problems of this kind, the battery autonomy is weak, 3G/4G consumes too many resources.
I know that in your case there are many complaints about battery autonomy, so please vote in the poll below.
