According to some reports and tests, apps are crashing more often in the new iPhone 5S. They crash twice as often on the 5S than they do on the iPhone 5 and iPhone 5C. according to tests by Crittercism, a mobile application performance management company.

But even with a doubled rate, crash frequency is still low across all versions of the iPhone 5. The iPhone 5S has a crash rate of about 2%. The original 5 and 5C's rates are at around 1%.

The 5S might be seeing more crashes than the 5C because of its new hardware, which wasn't available to developers before its launch.

The crash rate on the 5S should improve as developers have time to test their apps on the new hardware now.


"When you change a lot of hardware, you're going to have cases where issues crop up," Kalyan Ramanathan, Crittercism's chief marketing officer said. "Give it a few months. You'll see the crash rate render down to the norm."
