Apple says difference in the battery life of TSMC and Samsung made A9 chips is only 2% to 3%

Apple says difference in the battery life of TSMC and Samsung made A9 chips is only 2% to 3%
Amid talk that the A9 chipset produced by TSMC offers much more battery life than the one manufactured by Samsung, Apple released a statement this afternoon that says the difference in battery life between the two chips on the Apple iPhone 6s and Apple iPhone 6s Plus is no more than 2% to 3%. Samsung's version of the A9 chip is made using the 14nm FinFET process, while TSMC uses the 16nm FinFET process. Both companies have produced Ax series chips for the iPhone and the iPad in recent years.

Apple says that the 2%-3% difference is within the tolerance that is acceptable between two iPhone models, even if they had chips made by the same manufacturer. Which means that if the guy next to you is holding the same exact iPhone you own, and says that his battery life is running 3% longer than yours is, you have no complaint with Apple. 

However, a Geekbench battery test revealed that an Apple iPhone 6s powered by the TSMC version of the A9 would provide 1 hour and 5 minutes more battery life than the same model containing Samsung's version of the chip. In addition, the TSMC powered iPhone 6s produced a slightly higher AnTuTu score than an iPhone 6s powered by Sammy's A9. After the two phones went through the AnTuTu test the same number of times, the Samsung powered unit had less battery life remaining (71%) than the iPhone 6s with the TSMC chip inside (77%). That 6 percentage point difference is more than double the 3% variance that would be acceptable to Apple.

Of course, you can't truly go with benchmark tests to determine if one A9 chip offers a longer battery life than another. Real world results would probably be different, and could fit within Apple's acceptable tolerance range. By the way, earlier today we showed you a way to discover if you have a TSMC or Samsung made A9 chipset powering your Apple iPhone 6s, or Apple iPhone 6s Plus. No matter which chip you have in your new iPhone, Apple says that you are getting the same experience as others toting your model. After all, a 3% difference on a phone running 6 hours would be an extra 11 minutes, which is not enough extra battery life to lose sleep about.

Hey, that 2-3% might come in handy sometime lol. I understand why you had 2 manufacturers Apple, but I'd definitely want to know which chip I had if I had a 6s.

What? Sammy's 14nm is worse than TSMC's 16nm? See? You should never trust the numbers Sammy's bragging about.

The Samsung produced SoC was measured to be smaller, so that means there were no lies involved. A test run that cannot be repeated by others yet isn't exactly proof.

For once I agree with you! Many other factors may influence the final outcome. Samsung did pack more electronics into smaller surface area which is a plus point on space utilization but not from a heat dissipation point of view. In this instant I rather have the bigger SOC but too bad are can't cherry pick our iPhone.

The smaller SoC should produce less heat, there may be a lot of leakage which would be a manufacturing issue, but it doesn't make sense as FinFET is meant to address that.

No no there is a writer on Adam mills and this guy is by far the worst rumors ever

BTW guys this has always the case with basically anything made with silicon fabrication And it will probably always be a problem Google Silicon lottery Silicon binning

Thanks, but I already understood you guys published that story. I was saying that it would be important for me to know which chip I had IF I had a 6s, versus not looking at all lol. Sorry for not being more clear.

IMA walk up to an Apple Employee and be like: "Hey, do you guys have the Samsung A9 version of the chipset in stock?" See what they will say

They will say what they are trained to lie about and to say

Manufacturers can change components inside smartphones, e.g. in it's flagship devices Samsung use camera sensor from Sony or another one made by subsidiary company. And Xiaomi's Redmi 2 LCD-panel suppliers are Sharp and AUO. So many options.

Now ifans are in a dilemma lol either they hate their beloved iPhones for the bad battery life caused by a9 chips that's is designed by Apple and bought to life by Samsung which Apple say is the world most advance chip OR they gonna be force to love the iPhone simple because it's an apple product and ignore the battery life

As I have said on many of my posts, as the A9 soc was designed for 16nm this was always going. To happen as Apple just did a fast mod when they was unable to get the number they needed , that's clear as there are way more 16nm socs being used, also to get the 16nm to work it will had to have things setup to work best with it or it will have been a no go All if Apple did hahhahahahahhahahahhahahahh I do not think so, make a full design of the A9 for the Samsung 14nm then they will have had to change its setup by the soc or by software to lower what it can do, like a Samsung did with the 5433 next to the sd805 , but I think they just made a fast mod when they had to add Samsung to make CPUs So we then have like lower battery power and so on
