Download iOS 6.1.2 Released with Fix for Battery Life Bug – iOS 6.1.2 has been released by Apple. The minor update to iOS includes a resolution for a battery drain bug that impacted users of Exchange servers which also caused excessive data usage, but does not fix the passcode bypass bug that exists in prior iOS 6 versions, which is instead targeted by an upcoming 6.1.3 update. The brief release notes mention only this for the 6.1.2 update: Fixes an Exchange calendar bug that could result in increased network activity and reduced battery life. Users of Microsoft Exchange who experienced the excessive data use and battery life problems should be the first to update, but anyone troubled by the potential of someone bypassing the lock screen should also update soon. If neither of these apply to you, it?s still good maintenance policy to stay current with OS updates.
