A study by mobile app management firm Crittercism says iOS apps are twice as likely to crash on an iPhone 5s than they are on an iPhone 5 or 5c.
The app crash rates on the iPhone 5s are attributed to the unforseen issues that developers have had transitioning to the new internals of the iPhone 5s, such as rewriting drivers and code for the phone’s 64-bit A7 chip and M7 coprocessor. Apple notably began allowing developers to submit 64-bit apps for the iPhone 5s on September 16, just four days before the launch of the device itself.
“Anytime there is new hardware or software release, we see issues,” Crittercism CEO Andrew Levy said in an interview. “Inevitably, over time, those issues get resolved.”
Levy theorizes that the reason the iPhone 5s is seeing more crashes is because the hardware wasn’t available for developers to test their apps with ahead of release. While the iPhone 5c is nearly identical to the established iPhone 5, the iPhone 5s boasts a new 64-bit A7 processor, and the M7 motion coprocessor.
As developers get familiar with the intricacies of the new chips, its likely the crash issues will subside.
