As many iPhone owners already know, the iOS operating system provides users with a feature called Auto Lock that, when configured by the end user, can automatically lock the handset after a pre-defined amount of idle time. In other words, when your handset isn’t being actively used, it goes to sleep to save power and to secure your important data.
Auto Lock takes effect in most circumstances, however there are a few exemptions in which the feature gets overridden, such as during media (video) playback and while playing certain games. Some users like this because of its convenience, while others find it to be a concern both in terms of battery life and data security.
