Since Apple introduced iOS 4.3 last week, I’ve found a number of complaints about battery issues with the firmware update. I’ve even experienced these problems personally and I know many of you have too.
The update has caused issues with the battery life on my iPhone 4 and my iPad 2 is getting considerably less time out of its battery than my old iPad running iOS 4.2.1, so if you haven’t upgraded to iOS 4.3 you may want to wait until this issue is resolved.
According to users on Apple Discussions under the topics iPhone 4 – ios 4.3 – Battery Drain and iOS 4.3 causing battery drain, the iPhone’s battery life is severely shortened by the latest iOS update. As a result some users are also complaining that battery life is lasting 2 to 4 hours less than before the update was applied.
