According to performance monitoring by Crittercism, a mobile solutions firm, the freshly-released iOS 7.1 has a crash rate of only 1.6%. This is the best stability achievement in iOS's recent history, with versions from 6 to 7 having crashes of above 2%. For example, iOS 7.0.4 had an app crash rate of 2.1%, which means that either testing went over really well, or Apple has done an impressive work of optimizing the latest installment of iOS.
Reportedly, a significant number of iOS 6 users who hesitated to upgrade to iOS 7 have now switched to version 7.1. Also notable is how quickly the update was adopted. Ad network and analysis agency Chitika claims that 12% of the devices that accessed its ads were running iOS 7.1 about 45 hours after its release.
That's all fine and dandy, but Apple customers have been complaining of poor battery life, drops in connectivity, and random reboots since installing the update. Other users, meanwhile, have been enjoying their iDevices as usual. Either way, Apple has not yet commented on the situation.
