TSMC's A9 Chip Outperforming Samsung's in Early iPhone 6s Battery Benchmarks

I have the TSMC N71mAP for 6s: Im so pleased with my battery life!

For the comparison to be believable, you need to switch the batteries that are installed in each phone (which is easily done).

If the device with the Samsung A9 chip still performs worse despite running off the battery that was previously in the TSMC phone, then you would start to convince me. You can't attribute the difference in performance to the A9 chip (manufacturer) given that there are two variables here; the manufacturer of the A9 chip, and the battery the is being used in each device (given that battery performance can vary from one battery to another even though they come off the same assembly line).

To be convinced, I'd need to see consistent outcomes from 3 different phones (i.e. 3x TSMC devices vs 3x Samsung devices, with battery swap test included). But that's just me, and I'm a scientist.

Why do you have to swap the batteries? The batteries are the same, or at least should have the same build specs(correct me if I am wrong). It is the chips that are the only variable.
What is the justification for having to swap the batteries, without having to swap out every other component too, "scientist"?

I tied that app and it didn't work at all for me. It shows a few details but not that.

It is in the first tab and is blocked by an Ad. You need to tap 'Not now' to remove the ad first, then you will see your model number.

My problem with the screen grabs in the article is that the phone performing worst doesn't have a SIM installed, so perhaps it's spending more time and energy searching for a network than the other. Need some conclusive tests to account for simple variables.

If it doesn't have a sim, it's not going to bother searching for a network

I don't really think that the battery alone can contribute to such a big difference. If that is the case, it's a serious quality control issue. According to a Tweet by John Poole, the founder of Primate Labs / Geekbench, the distribution of battery test results of 22 iPhone 6s is not normal:

I thought this article was a click bait until I saw this tweet.
 
I won't be convinced until another u tube video surfaces showing another comparison between these chips.

By design a GSM phone cannot connect to any network without a SIM. So it's not going to search for networks. Actually, from my experience of using old dumb phones, at least a deactivated SIM is required for the phone to even boot up.
 
Is it me, or does it seem that the overwhelming majority of all comments on Macrumors are of sarcasm?
There are far too many people trying to be "funny and or witty", although fail miserably.
I'ts getting super lame.

Like others have said already, this can't be considered as facts at all. You need to test things like this in controlled environments, make sure everything is identical on both devices and run the test multiple times. You should even run it on multiple devices to rule out variables like varying degrees of batteries and whatnot.

All I can really gather from this is that there is no reason to believe the Samsung 14mn FinFET should be considered superior to the 16nm TSMC as it stands currently. So there is no real reason to be upset if you get one or the other.

Exactly.
A single phone is statistically insignificant.

But just imagine if you had two hours extra battery life with the TSMC chip.

You might be even happier. :eek:

Really doesn't matter since I get faster speeds and I always have plenty of battery life after a full day of use. My phone can sit for hours and not drop a percent. This is one of the best and longest batteries I have had in an iPhone and I have owned them all.

I have no idea which chip I have.

This should be relatively easy for a more trustworthy source to test. Unless and until that happens, this could be hysteria over nothing.
