Apple just released the iOS 10.2.1 update. It follows on the heels of iOS 10.2, the larger release that hit in December and introduced the new Apple TV app, new Emoji, updates to Photos, Messages, Movies, Mail, Accessibility and more. Today’s update is much smaller, as the name implies.

According to Apple, iOS 10.2.1 includes “bug fixes and improves the security of your iPhone or iPad.” It’s not immediately known, but I’m curious if anything inside of the update helps solve some of the battery life issues related to the iPhone 6. Apple had been working on a software patch that was supposed to help it diagnose issues, though it was otherwise issuing battery replacements to iPhone 6s owners.

We’ll let you know if any big changes surface, for now know that it fixes bugs and improves the security over iOS 10.2.
