iOS 5 battery issues are real, Apple deploys a fix with 5.0.1 — but it's not over yet

After iOS 5 was released, many users began reporting battery life problems. After some time, Apple confirmed that the problem is real and a fix is coming. The leading candidate could be iCloud sync, but Apple's Developer Beta for iOS 5.0.1 only mentions "bugs affecting battery life." The release finally came on Thursday, November 10th — but on the 11th, Apple released a brief statement saying that a "few" issues remain.
