iPhone 6+ S 64GB. Been amazing in every way. I have TSMC. My friend has Samsung. The first 3 tests we ran i was faster. Both phones have zero lag or issues, and as good battery as our last iPhone 6 Plus versions. These phones both smoke anything we have ever used, amazing in every way. No yellow tint, and they both run extremely cold.
However the Samsung is on AT&T and the TSMC is on T-Mobile and the one on T-Mobile smokes the Samsung phone on web browsing and downloads and overall network quality seems to affect the phones performance a lot more then processor.
I think this chip difference is a non-issue and is not related to problems customers are experiencing with freeze, lag or temps. Those are probably software issues.
