iOS 8 offers a number of improved productivity services, but it has suffered one of the slowest uptakes ever seen in the Apple ecosystem.
The latest official statistics from Apple show that just 56 percent of iPhone and iPad owners have upgraded to iOS 8 since it was released many weeks ago.
This is likely to be down to the myriad bugs uncovered in iOS 8, including software instabilities, battery drain, increased handset temperatures and sluggish performance.
The bugs have led many iPhone and iPad users justifiably to hesitate before upgrading to the latest iOS 8.1.1 software.
Apple iOS 8.1.1 is the fourth update to iOS 8 and was released on 18 November. It is available now as a 64.1MB download for the iPhone 4S and above, iPad 2 or later, iPad Mini and above, and iPod Touch fifth generation.
Rather than adding a wealth of new features, OS 8.1.1 is designed to fix under the hood performance and security issues in iOS 8.
Specifically iOS 8.1.1 promises to fix the software instability, battery drain, handset temperature and sluggish performance reported on older devices, such as the iPhone 4S and iPad 2.
The iOS 8.1.1 update also fixes a privacy issue which meant that browsing data may have remained in the cache following deletion by the device's user.
The update also addresses an undisclosed security issue in iOS 8 that could theoretically have been exploited by hackers to execute code on iPhones and iPads.
Other security updates include a fix for an "occasional problem" where iPhone and iPads lockscreens would not not limit failed password attempts, and a patch for a flaw in iOS WebKit that could let maliciously coded websites execute code on iOS 8 devices.
Update and download
Users who wish to update to iOS 8.1.1 can do so either as an 'over the air' download from their iPhone or iPad or by using iTunes on their computer.
To get the update 'over the air' users should connect their iPhone or iPad to a stable WiFi connection and go to the software update section in the device's settings menu.
