Apple Says Real World Battery Life of iPhone 6s A9 Chips Vary Just 2-3%

Apple has released a statement to address reports that an iPhone 6s with a TSMC manufactured A9 chip gets longer battery life than an iPhone 6s with a Samsung manufactured A9 chip.

The company says that tests which have shown a nearly two hour difference in battery life are unrealistic.

"With the Apple-designed A9 chip in your iPhone 6s or iPhone 6s Plus, you are getting the most advanced smartphone chip in the world. Every chip we ship meets Apple's highest standards for providing incredible performance and deliver great battery life, regardless of iPhone 6s capacity, color, or model.

Certain manufactured lab tests which run the processors with a continuous heavy workload until the battery depletes are not representative of real-world usage, since they spend an unrealistic amount of time at the highest CPU performance state. It's a misleading way to measure real-world battery life. Our testing and customer data show the actual battery life of the iPhone 6s and iPhone 6s Plus, even taking into account variable component differences, vary within just 2-3% of each other."

A 2-3% difference in real world tests is still more than expected; however, it's unlikely that you will notice it, especially given the new Low Power Mode in iOS 9.

If you want to check which chip you have in your device, follow these instructions.

Wel Apple just confirm that there is a difference. I'm curious if they new about it. Probably. Anyway, information is power and the consumer can decide what chip they want. I have a Samsung in my 6s plus 128gb but I don't care much about the power difference. I also don't condemn if someone wants to return because of the inferior (albeit small)chip. Consumers decision. And again apple learns a lesson. They need to tighten the tolerances. We all get a better product in the future because of this.

Nothing really shitty about iPhones. It's just luck if you have one or the either, but not like it matters that much to them anyway. I am happy with mine being whatever is has on the inside as long as it survives.

Chipgate? Or Cheapgate?

From what articles say...^

Is this why Apple included Low Power Mode? To offset the real-world difference between the 2 chips?

The one with wifi and cellular turned on has a longer battery life. The other with only wifi on has a shorter battery life. The shorter battery life one uses the Samsung chip. Right?

Go and check it out yourself. It's as I said.

One says wifi only , other has cellular data and wifi active.

Apparently, not you!

It doesn't matter about real world or not, if you test the battery and it dies an hour or two faster with one chip instead of another chip, then that's proof that is the bottom line

Smh @ Apple. Looks like we've been played again.

maybe the brightness is too high, all the apps installed are running and not turned off, and everything that works with antenna turns on like wifi, bluetooth, lte, location services. Try proving battery against all of this part of it at once.

Simple, a fresh restore, no SIM card in either of them, just get on wifi to download the testing app, then turn everything off, put it on never lock the screen, put the brightness all the way down, and then time them, she which one dies first. Simple, if all the settings are the same(which would be from a dfu restore) then you would be able to test accurately.
