just throwing around these false claims all over the place. If that was the case then ~80% of 6s would be defective since that is the ratio of TSMC/Samsung.
Got a tip for us?

You are the only poster here who claims to have enough information to support such a thing. Stop trolling.

his numbers are not wrong
your statement also makes no sense. you say its 10% less power efficient so they have to throttle it to make it meet a thermal spec? what does power efficiency have to do with thermal? the tmc chip is still an a9 which is more powerful than the a8, so why are our iphone 6's not doing the same thing? we would also know already if these 2 chips were clocked differently

That graph is taken from people who have a problem with their phone and installed the app to find out if they have a defective TSMC chip. This graph not representative of all iphones. All this graph does is show that the TSMC chip is more problematic than we initially thought hence the reported TSMC numbers.his numbers are not wrong

ok, I installed it and my first phone was samsung and my current phone is TSMC. The samsung had reboots etc.....explain that to me? I replaced my phone to change colors.
zero lag, reboots, anything.
This is why I tell people to set up their phone as NEW and not from backup. I tested this as well by reloading a backup from iTunes to my 6s plus then there were tons of lag, Touch ID issues and lag of the screen movements. I set it up as new and no problems. Whenever you do a fresh install of the OS on the new phone it will perform like it's supposed to.
Everyone has their opinions about restoring from backup but I guarantee you if you took it to apple, first they'll ask is if you restored it from a back up or set up as a new phone. Try setting it up as a new phone OP.

That is as far as the facts go.
This on the other hand is pure conjecture.
It's actually FAR more complicated than "smaller sign rules = better".

This is a software issue, it was happening on iOS 9.0.1 on my old iPhone 6 as well (and new 6s).

This is the first time in years, like 4 or 5, where a backup actually caused problems with an iPhone for me.

My day job is as a hardware design engineer. You?
At the first level a smaller chip doing the exact same work has to dissipate the heat generated over a smaller area. This is bad, not good. at the very first level also making interconnects smaller generates more heat as well. The power savings of moving to smaller design rules are achieved by changing the surrounding system, not simply by changing the chip.
So, what system level compromises/tweaks/optimizations did Apple have to make to allow for these two chips to be used interchangeably?
What do you know about Samsung and TSMC's packaging technologies? Do they have the exact same thermal dissipation properties?
Do we even know if the TSMC/Samsung parts all come from a single production line within TSMC/Samsung? I sincerely doubt it given the volume.
Most of engineering is in finding the acceptable balance and compromise.
Finding root cause for a hardware problem is a long laborious process where the smoking gun is not always a good indicator of the problem.
How do you know for certain that the correlation is with chip vendor rather than, for example, Apple's contract manufacturer and finished assembly line?

On your phone go to this site and install the app
http://demo.hiraku.tw/CPUIdentifier/
Then go to settings----general----profile----and trust the app.
Open the app and it tells you

Just stop spreading FUD all over the forums already. When you have an iota of evidence come back. to the issue.

I had the issue again today on iOS 9.1 public beta 2.
I am updating to public beta 3 tonight, so we will see if the issue still happens then.
I tried to install that CPU identifier app, but all I get is a screen that says it can't be downloaded at this time. I cannot remove it from my home screen now either.
The only profile that shows up is my beta profile.
Any idea on how to remove it?
If this issue happens again I will be restoring and setting up as new. If it happens once more after restoring as new, then I'll take it in Sunday.

Awesome! I'm glad I could help! I'm thinking of posting a new thread about this issue and how to resolve it ha. I feel like a free online tech support.
I think I have narrowed my issue down to Wi-Fi.
The only times I have specifically noticed it start to screw up is when my phone is locked and connects to Wi-Fi and I try to unlock it.
It took a while with the lag but once I disabled Wi-Fi in the control center things went back to normal.
I reset my network settings, so hopefully that helps.

I don't think it has to do anything with the wifi personally. it's the OS corruption. set it up as new.
