    Ian not sure if you covered this but if I use a overlay how would I use the percent stuff so it fits all phones

    Never mind I got it. Very cool stuff Ian thank you

    Interesting theory, Simon.. Would be consistent with why we get less "white screens" (WK crashes) on a 5 than a 6plus too. But doesn't help dispel the RAM versus CPU conundrum - does it?

    This is how I explain it. All this points to RAM. Just because it consumes less CPU usage doesnt mean that this is why it doesnt cause resprings.

    Also, you asked to see data to support this opinion. I would love to see your data for once as to why you think it isn't RAM. Show me that then I too will modify my opinion.

    I actually didn't challenge anyone to show me proof, Krima. I said I would love to read some technical articles supporting the insufficient RAM position and thought I made clear that the 'only' basis upon which I have my opinion is the WKWebView versus UiWebView benchmark results which RKO posted here and in GCF a couple of times now. (Too lazy to go find links again- but pretty easy to find for yourself.)

    So between those benchmarks (which compare only CPU performance between WK and UI) and the argument I laid out two posts ago - that's how I've come to my conclusion. I would just like to see some data that shows that the auto resprings happen as a result of RAM running out. Crash Reporter shows a crashed Springboard after the auto resprings but doesn't list it as a RAM insufficiency like when an app crashes. I would just love to be able to test for an actual RAM crash so I'd have some empirical evidence to sway my opinion in another direction. The data from the BenchMarks results, showing that WK uses a tenth of the CPU that UI does, has been the only data that seems to fit all the phone behavior we've seen. It explains perfectly (for me) why there'd be less less resprings on an iPh5 and the most resprings on a iPh6+, which, logically (to me), uses the most CPU power of all phones.

    I'm pretty sure that when our phones run out of CPU power they will respring just like when they run out of RAM. Pretty sure someone educated us about that a while back.. But correct me if I'm wrong..

    The biggest deterrent to the "it's all about RAM" position, for me, is that it can't explain logically (to me) the near complete absence of auto resprings on an iPhone 5 with 1GB RAM and the respring city level of autoresprings on an iPhone 6+ with 1GB RAM - both running iOS8/UIWebView. And if we want to say - that the 8.1.2 firmware running on a 6+ uses more RAM than the 8.1.2 firmware used on a 5 - then you also have to explain why some 5's and 5s's ALSO get resprings in UI 'at all'? A conundrum.

    I'm swayable. I just need to hear a real good argument for the other position. Haven't heard one yet.

    You do realize the higher the resolution of the device is the more ram it needs to run right? Maybe even more so than cpu. So RAM fits just as perfectly as the reason showing why the larger screen iPhone 6 plus and 6 have more resprings than an i5. By default they are using more ram because of their larger screens.

    Would love to see any data that supports this. I personally have never heard or read anything that would support such a statement. I've seen the benchmarks regarding CPU efficiency. That information does nothing to support what you guess here.

    Not saying it isn't possible but I have never heard that CPU running low will cause your phone to respring.

    Show me where you got that opinion.

    To me it does based on your conclusions from the cpu benchmarks you mentioned. If my theory is right then wkwebview isn't crashing any less than uiwebview. So if cpu useage is so much less or more efficient in wkwebview then it can't be the cause of the crashes since wkwebview is still crashing. Understand?

    Yes. That's the actual argument I made at the beginning too.. And it's still the best one for that side of the argument.. But where it breaks down for me is that WKWebview can run full animation with zero resprings on a 6+ with only 1GB RAM just like an iPhone 5 can run UI with little resprings. What seems to be the only difference (data-wise) between WK and UI? CPU usage. That's where the whole argument changed for me - after I saw those benchmark results.

    Simon - two things:
    1) Do you think it's possible WK uses 'less RAM' to run HTML than UI does?
    2) Do you think UI would be respring-less if there were 2GB of RAM on our phones now? It so - why?

    PS. I'm perfectly happy to take this to great debate -if you want Simon. For the sake of Ian's thread..

    Oeps...

    What have i done.
    A huge discussion about ram.

    I only posted a tiny massage...
    Back to my coffee.

    1) Don't know. Haven't seen any comparisons on ram between the two.
    2) Not completely no. But definitely less IMO. I know it's not a direct comparison but as I said before my iPad Air 2 has 2gb ram and it is by far the device for me that resprings the least running uiwebview platforms.

    These answers don't really matter though if my theory above is correct. If that is true the only thing that changes between uiwebview and wkwebview is what happens as a result of that crash.


    @Ian if you want me to move these respring posts out of here into the great debate thread just let me know and I'll move them.
