Why is my iPhone 5S crashing twice as often as my previous iPhone?


Have you noticed your brand new iPhone 5S crashing when running your favorite apps lately?  According to the CEO of Crittercism Andrew Levy, the newest iPhone has been crashing at “much” higher rate than on both the iPhone 5 and the newly released iPhone 5C.  Based out of San Francisco, Crittercism provides mobile app developers a way to monitor their app’s performance.  After monitoring “hundreds of millions” of app launches, they noticed a major jump in app crashes with apps running on the iPhone 5S.

App crashes are nothing new, especially with newer versions of operating system releases.  Bug and crash reports are key to fine-tuning the OS.  Apple has already released two updates to iOS 7, so it’s good to see they have been very responsive to the data that’s been collected thus far, and we should expect the crash reports to diminish over time.

Levy provided some insight as to why we might be seeing the higher rate of crashes,

…while developers were able to check their apps for compatibility with iOS 7 during several months of beta testing, the new hardware wasn’t available ahead of time. The iPhone 5s packs a new 64-bit A7 chip and an M7 coprocessor, while the 5c is nearly identical, internally, to the iPhone 5.

Now while initially this increase in app crashes seems like an anomaly when referring to iOS apps, the numbers are still nothing to be too alarmed about.  The total number of observed crashes have only been observed about 2% of the time of all app launches versus just under 1% on the iPhone 5 and 5C.  What has your experience been with app crashes on your iPhone 5S?

    I wonder if part of the cause could be traced back to the magnetic sensor inaccuracy mentioned elsewhere for the 5S and 5C.

      I don’t think so. The 5C isn’t crashing with anymore frequency than the iPhone 5 did. The 5S hardware wasn’t available to developers ahead of time, and it’s been suggested that as a result, the 64-bit A7 processor and new M7 coprocessor didn’t get the same beta testing time-frame to iron out the wrinkles. The good news, though, is that it looks like the crash reports are expediting the process like they are designed to do.

    This is why waiting in line all morning for this device was inane. Not just the iPhone, but nearly all new devices experience some sort of bug. The difference is, you don’t see people waiting 3 days in line for anything but the iPhone.

    I’m sure apple is looking into it and will release a patch just like other manufacturers do with their phones. Of course if i paid full price for the phone or signed a new 2 year contract to get the best of the best I’d be mad if my phone kept crashing. My wifes iphone 4 rarely crashed and my note 2 also. The 4s was even better. I’m sure its software related and it can be fixed pretty easily. At least you hope.
