In the patch notes for the iOS 13.1.1 update, one of the fixes includes addressing a potential battery drain for some users. If you are experiencing battery drain, then this could be an update worth checking out. However, even if you aren’t experiencing battery drain, it might still be an update to download, especially if you use third-party keyboards.
Earlier this week, it was reported that due to a bug, it gives third-party keyboards full access to your device even if you did not. This means that some keyboards might have access to more data than you would like or be comfortable to give. However, the iOS 13.1.1 update will fix that so if you use third-party keyboards like Gboard or SwiftKey, you’ll want to patch it ASAP.
The iOS 13.1.1 update mostly focuses on bug fixes so don’t expect any major changes.
