Apps on iPhone 5s Reportedly Crashing Twice as Often as on iPhone 5c and iPhone 5

According to a study by mobile application mangement platform Crittercism, iOS apps are twice as likely to crash on the new iPhone 5s as they are when running on the iPhone 5 and 5c, reports AllThingsD.

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 said that perhaps the reason the iPhone 5s is seeing more crashes than the equally new iPhone 5c is that, 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.

However, the company compliments Apple for releasing two updates in quick succession for iOS 7, stating that the company is "doing a really good job of addressing these issues as they come up." Since its launch last month, a number of noteworthy apps have been redesigned or optimized for the iPhone 5s, with more developers stating that they will update their apps to accommodate the new processor in the near future.

Yep, I've noticed this.

New processor = more optimization.

It'll get worked out, but it sucks right now.
 
I'd say once or twice I've had iTunes Radio crash. It's like the phone locks up, gets really hot in the back for about five seconds, and then reboots.

Otherwise it's been great.
 
I had my 5S since the start no crashes for me, my iPad mini has had a lot more since upgrading to iOS 7, especially with Mac Journal.
 
My 5S has had a noticeable amount of crashes, but apps start so fast on the 5S that it's not too much of an inconvenience to open them up again. It's also my first iPhone, so I can only compare it to my old decrepit Android phone.
 
Does this explain why iWork apps give the blue screen of death...

Even apple doesn't know how to code their own apps for 64-bit.

my samsung galax...... oh wait

steve would have never..... oh wait


glad my iPhone 4 is still working with a reduced battery life :D

guess I'll wait for iPhone 6 and OS 7.1 instead
 
I've had a few app crashes so far on the 5s, but I've also had two spontaneous reboots and a forced reboot (unresponsive screen) at the OS level.

It's not horrible by any stretch, but it does get annoying.
 
Hence why I'm skipping iOS7 all together and waiting for iOS 8. I felt like this release was rushed with all the work being done on the "makeover". This reminds me of iOS 3.

Hey, leave Android out of this discussion! That was a low blow.

At least Google's native icons are consistent. :D
 
My 5S kept rebooting multiple times a day. I don't think I ever had any apps crashing but the reboots were so bad that I am getting it replaced by Apple. A restore and fresh start didn't change anything.

I've read of other people on different devices than the 5S having random reboots on iOS 7 too so I can't really tell if it's the hardware or software or both..
 
My iPhone 4S w/ iOS7 experience has been nice but also problematic with apps crashing, stalling, or having to refresh completely even after just a second of multitasking over to one app and then back. I understand I have "old" hardware, but it's still frustrating... I can only imagine how people would feel if they bought a brand new iPhone 5S and experience the same or more annoyances.

Yeah, 64 bit some developers, all right.

I could go off on a rant about Objective-C and iOS memory management practices in apps and libraries, but the basic problem is that it allows programmers access to pointers and, if you work with C structures, even allows you to allocate based on size. These are the things that kill apps in transition from one memory model to another. Modern languages like C# and Java isolate the programmer from these things, and you can develop code that runs equally well on any architecture, with the libraries and runtime handling any interaction with non-managed components.

Programs should never make any assumptions about the size of addresses, values, structures, or objects.

Much more annoyances. Constant random reboots on my 5S.
 
Anyone reading this shouldn't be scared off a 5s. I've little doubt this'll get fixed, and it's certainly not unusable, but iOS 7 is already a bit buggy, and the 64-bit version that's currently only on the 5s is a bit buggier still.

They're compiling stuff for ARMv8 instead of v7 which the iPhone 3gs through the 5c all use.

I've had the settings program crash on me quite a bit, and was unable to set up more email accounts until I rebooted (then everything worked normally). A day ago my visual voicemail quit working until I rebooted.

It's way more buggy than my Windows Phone 8 Nokia, but I'm sure it'll get patched up over the coming weeks/months, and it's not THAT bad now that it should really scare anyone. I wouldn't get a 5c over it, not for only $100 less. (Now for half price I'd get the 5c!)
