Study shows apps are twice as likely to crash on the iPhone 5s

If you’re using an iPhone 5s(s aapl), apps are twice as likely to crash for you as they are on an iPhone 5 or an iPhone 5c, according to a new study by app performance monitoring company Crittercism. All Things D spoke with Crittercism, which shared details from the study and offered some possible explanations.

Crittercism has monitored hundreds of millions of app launches since the iPhone 5c and iPhone 5s became available, and observed that apps have a typical crash rate of around one percent for the iPhone 5 and the iPhone 5c. On the iPhone 5s, on the other hand, apps crash two percent of the time.

What makes the iPhone 5s more prone to crashes? “Anytime there is new hardware or software release, we see issues,” Crittercism’s CEO Andrew Levy told All Things D. “Inevitably, over time, those issues get resolved.”

Levy suggests that while developers were able to make sure their apps were compatible with iOS 7 during beta testing, they weren’t actually able to test apps on the latest iPhone 5s hardware. The iPhone 5c is virtually identical to the iPhone 5, which is why the phones perform the same. But the iPhone 5s uses Apple’s new 64-bit A7 chip, and compatibility issues could be causing the crashes.

“The good news is that Apple is certainly aware of issues,” Levy said. “They’ve pushed out two iOS updates for iOS 7 … Apple is doing a really good job of addressing these issues as they come up.”

Anecdotally, I’ve been using an iPhone 5s for two weeks now, and I can say that I’ve noticed more frequent app crashes than I saw on my iPhone 4s. The crashes are still few and far between – maybe 2 or 3 so far – but it’s more than I was used to seeing. Hopefully Apple will resolve this issue in a future update.
