Only four percent of iOS device owners upgraded to the latest iOS 8 version of the operating system in the past two weeks, according to stats from Apple.
Apple's developer page shows that 56 percent of iOS device owners are now running the latest version of the OS, up from 52 percent.
This slow growth comes despite the release of iOS 8.1 on 20 October, which contained several fixes and stability improvements, and saw the return of the Camera Roll and the launch of Apple Pay.
This is clearly not tempting everyone, though, as 40 percent of devices remain on iOS 7.
This could be caused, in part, by the fact that the original iPad and iPhone 4 cannot move to iOS 8, and these devices no doubt still account for millions of Apple device users.
Others may still be put off by concerns that moving to the newest version of the operating system will result in more problems than benefits, given that several issues blighted iOS 8 when it was first released.
The iOS 8.1 update was designed to rectify many of these glitches, and no major problems have come to light since it was made available on 20 October.
Security experts have said this represents a new era in the mobile malware market as cyber crooks finally find ways to exploit the iOS ecosystem.
