Since the release of iOS 5, many iPhone users noticed significantly decreased battery life, sometimes draining the device by more than half of its capacity overnight. Apple released iOS 5.0.1 to address the issue, but the update failed to fix issues for many users.
The recent iOS 5.1 update aimed to fix that with “improved battery life” mentioned in the release notes, but just how improved is it? With casual use since the update was released, the consensus at OSXDaily suggests the improvement is substantial, and thus if you haven’t updated your iPhone, iPad, or iPod touch to iOS 5.1 yet, it is highly recommended to do so now.
I have noticed significant improvements on both my iPhone 4 and my iPhone 4S as well, and many people that I’ve spoken with agree (even though early betas of iOS 5.1 did not address the issue). What about you? Are you noticing increased battery life since updating to iOS 5.1? Let us know!
