I can not believe Apple provided following explanation on this issue:
“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.”
What is the definition of " real-world battery life" ? If people got the phone and use it in whatever way they can use it, isn't it "real"? Apple did not deny the result of this test, but just implied this test was not the "right" way to use iPhone. I can see Apple's highest quality commitment to customers is not real from this case. The test was done with exactly the same software with 2 iPhone in 2 different chipsets and ended up with different results (significant difference on battery life), how can it be a problem with the test?
I think Apple has better to stop making or selling iPhone 6S and 6S plus with Samsung Chipset and recall all the Samsung chipset phones, this is the best way to show Apple's highest quality commitment to customers.
