More battery life tests on iPhone 6s A9 chips


Andrew Cunningham for Arstechnica:

So there are definitely circumstances under which the TSMC phone will last longer than the Samsung phone, but it's not a universal problem. A Samsung chip that's mostly idling or even one under modest CPU and GPU load, though, is going to behave in just about the same way as a TSMC chip. And the kinds of CPU-intensive work that the Samsung chip seems to struggle with just aren't that common on smartphones. Most of the time, iPhone 6S battery life should be similar no matter which chip your phone is using.

So, seems yes there's a difference, and while technically it can be significant, practically it's not.

I apparently have a phone with a TSMC chip, so I guess yah for me.

I suspect Apple fears people will start exchanging phones, perhaps repeatedly, to simply get the phone most theoretically optimum chips.
