Apple updated their official developers page Tuesday showing that their new iOS 8 passed the 50 percent mark on all Apple devices six weeks after its launch, Venture Beat reported. 

Apple's latest operating system update started off with 47 percent in total user upgrade last Oct. 5 against its predecessor, the iOS 7, which raked in a similar 47 percent. By Oct. 13, the percentage ratings for iOS 8 jumped to 48 percent, while the numbers for iOS 4 stayed steady at 47.

The iOS 8 recently clocked in at 52 percent during its latest measurement on Oct. 27, according to Apple's support page for developers. This puts the iOS 8 above the 43 percent user percentage recorded for iOS 7.

Apple's latest mobile operating system update has a notably slower adoption rate compared to its predecessors, according to mobile app tech platform Tapjoy.

Tapjoy gets over 200 million iOS impressions from their ad network and released figures showing that the adoption of the iOS 8 was slower than not just the iOS 7 but possibly even the iOS 6.

iOS 8 clocked in at under six percent of user upgrades in 18 hours after its initial availability, which was notably lower than iOS 7's user upgrade of over 14 percent and iOS 6's estimated eight percent within the same time period.

There are many possible reasons for the slower adoption rate of the iOS 8, the biggest reason possibly being the size of the update.

The iOS 8 needs 5GB for its upgrade, which many users may find too much given the data memory they could use for photos, videos, apps and music instead. It may also be possible that users are wary of bugs or are simply not impressed with the features available.

The low adoption rate of iOS 8 may also be the cause of the errors in the iOS 8.0.1 patch that followed the release of the new software update, according to the Apple Insider.

The updates resulted in a launch-day bug, or an Error 404 Content Not Found, that affected HealthKit-enabled apps, Photos, third-party keyboards, Reachability and more.

The update was pulled out and an iOS 8.1 was released in its place and so far the latter is more stable compared to the former.
