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.

According to AllThingsD's John Paczkowski, Apple has just released the following statement regarding iPhone battery life in the just-released iOS 5.0.1 update:Read Article >
What makes the statement interesting is that iOS 5.0.1 was ostensibly developed (and pushed out so quickly) primarily to solve battery complaints that had been coming from iOS 5 users on the iPhone 4 and 4S, so Cupertino still has a little bit of work to do. Is there an iOS 5.0.2 in our near future?

iOS 5.0.1 has been made available to the general populace by Apple, a build that promises to improve battery life. Other changes include the addition of multitasking gestures to the original iPad, unspecified "bug fixes" for Documents in the Cloud, and improved voice dictation for Australian users — it would seem iOS 5 didn't appreciate that Aussie accent.Read Article >

Apple didn't say exactly what the "few bugs" were, but leading candidates right now are iCloud sync and notifications. Apple has just posted a developer beta for iOS 5.0.1, with the following changelog:Read Article >
Emphasis ours above. Hopefully Apple will be able to stick to, or even accelerate, the "few weeks" timeframe it gave to All Things D. In the meantime, we'll be sitting in our Apple Core forums, looking for interim solutions.

Speculation on the cause is running rampant; some people blame a location-based time zone setting, others find trouble with iCloud contact syncing, still others have seen a bug involving calendar reminders in the iOS 5 notification pane. These problems aren't limited to iPhone 4S users, either — many iPhone 4 users are complaining the upgrade to iOS 5 has hurt their battery life. Recommended fixes include disabling the time-zone setting, removing calendars from Notification Center, and wiping, restoring and re-syncing contacts, among many other suggestions.Read Article >
Although we found battery life of the iPhone 4S to be quite impressive — and plenty of users posting strong performance — it's hard to pinpoint an exact cause without Apple speaking up. While the company hasn't addressed this issue publicly yet, The Guardian reports that Apple engineers are actually contacting iPhone 4S users directly, asking questions about usage and collecting data to try and find a solution. Additionally, some posters in the 160-page battery complaint thread in Apple's forums have noted they were easily able to get their phones replaced at the Genius Bar. Hopefully the fact that Apple's engineers are soliciting feedback is a sign that a fix is coming.
