Apple released iOS 8.1.3 on Tuesday that reduces the amount of free space required to install the OTA update, while also bringing other fixes and enhancements.
When Apple released iOS 8, many complained about the inability to install the update over-the-air (OTA) because of limited free space on their iOS device. This issue has often been blamed for the slow adoption rate of iOS 8 compared to its predecessors. With iOS 8.1.3, Apple looks to have addressed this problem, with some claiming they've been able to install the update on devices with less than 0.5GB free.
Apart from this much-needed patch, iOS 8.1.3 also brings a fix for an issue that can prevent some users from entering their Apple ID password for Messages and FaceTime, while also addressing an issue that cause Spotlight to stop displaying app results.
iOS 8.1.3 release notes:
This release includes bug fixes, increased stability and performance improvements, including:
* Reduces the amount of storage required to perform a software update
* Fixes an issue that prevented some users from entering their Apple ID password for Messages and FaceTime
* Addresses an issue that caused Spotlight to stop displaying app results
* Fixes an issue which prevented multitasking gestures from working on iPad
* Adds new configuration options for education standardized testing
