Apple Said to Be Stopping Use of TLC NAND Flash in iPhone 6 and 6 Plus After Reported Issues

Thank you.:) I'm really curious if this static/pop/crack sound is related to this TLC NAND issue?
But i may be wrong, but have been thinking that this problem only happens often while loading,
and will cause a millisecond lag (static/pop/clack) with my music on.

Nonetheless i don't want to make false statements for now.
Although i have tried everything i can think of to get this issue solved, so i'm out of idea's at the moment..
And i also find it really strange that not many people have experienced this issue.

But two of my friends do have it, but they didn't really noticed before i told them to replicate this issue.
Both of my friends have the same Iphone as me, Iphone 6 Space Grey 128GB with TLC NAND equipped.

Or it could be just me, since i'm a OCD person and i do noticed this issue.
I searched google for this problem and called around and nobody knows about it..

In all disk benchmarks, my 128GB TLC iPhone 6 is 90% faster than an iPhone 5S with MLC. Your iPhone may be faulty, but for sure it's not related to the NAND speed.

iOS 8.1.1 does not fix it

Why ? IOS 8.1.1 addresses the issue.

Actually it doesn't, I'm running iOS 8.1.1 on a 64GB iPhone 6 and it crashes at least 1-2 times a day during normal use of Safari and Mail without even bringing third-party apps into the mix
 
This is interesting and seems to contradict the rumors about Apple switching back to MLC (source is Samsung).

This analysis actually predicts TLC to take over the vast majority of sold NAND chips few years from now... I bet all 2015 Apple products will probably use TLC.
 
Hi this is my iQuickmark singlecore flashtest benchmark on an iPhone 6 plus 128GB first Day device 562 apps installed with TLC and Toshiba Flash - look at the horrible 4K random write result in comparision with other 6plus devices.

Really strange! Have you tried after a reboot and with all apps closed? I have a Toshiba 128GB TLC and my random writes are around 4700!!
 
After closing all apps I have even worst results. Interestingly the last 4k test seems to be better than the result of other iphone 6plus.

These results are really unexpected. Only thing I can imagine, there are different TLC 128GB chips out there, some are excellent and fast, some are terribly slow...

My results are totally different!

I repeated the test and now the results are better, but far away from 4000 - does it mean that the benchmark doesn't work properbly?

What the ... - seems that I've the lamest iphone 6plus on earth - or are these the results, because I don't remove the adds? Ok you've one - I'll spend now the 89cents
 
Strange thing - I removed the ad, killed all widgets now, turn off bluetooth and restarted the device - see the results now - But holy cow - fare away from 7000?!

I told you. The ads would never make such a difference. Does the device feel slow while using it?

Did you feel that your phone is slow? Or it feels snappy?

Only if they use Samsung.

From I read, Samsung is at least two years ahead of everyone else with TLC NAND. Maybe more.

They've even gone on to using 3D structures to stack 32 layers of cells on top of each other, which packs in more memory at higher access speeds. Toshiba and Sandisk are supposed to begin their own 3D production sometime in 2016 at a new factory.

Interestingly, Micron Technologies doesn't list mobile phones as a viable target for TLC:

When I use it for longer times, it's getting slower and slower - iOs 8.1.1 helps a bit - for example during iOS 8.1 my Phone crashes every time after 15 Minutes of telephoning via bluetooth. This does not happen any more - till now

So i hope it stays stable. But the results are real strange. Maybe you should consider to swap it at a apple store.
 
Yes indeed - after another restart the results are now about 2500 - so the results are not stable. I think my device has some kind of slow ugly cells - and when they are randomly used by the benchmark the results goes down
