Apple recently pushed out iOS 6.1 which had many new features including updates to Apple’s Map app and Safari, but a few of those features were unintended. iPhone 4s users have been experiencing poor cell phone performance along with other issues. Other bugs also plagued Apple’s mail app, causing network problems when iOS 6.1 devices connect to networks with other mail clients like Microsoft Exchange.
Yet another issue that has popped up with this update included battery life problems as well. If you own an iPhone 4s you should make sure you’re up-to-date with the latest update from Apple (6.1.1). Of course if you haven’t made the update to 6.1 then you should be also fine.
