（其实看第一段就够了）
Over the past several days, a slew of battery tests on the iPhone 6s and the
iPhone 6s Plus have revealed some performance differences between
models that have an A9 chip manufactured by TSMC and those with an A9
chip created by Samsung. While variousbenchmarking and real world usage
tests have shown differences of 6 percent to 22 percent, in favor of TSMC
chips, Apple says that its own testing has shown battery life variations of
only two to three percent.
在过去几天，有大量两种版本芯片制成的6s与6s plus的电力测试。
台积电与三星的A9芯片，在多方测试之下，有着6~22%的电力续航力差距。
但是苹果认为，实际的差异只有2~3%而已。
In a statement given to TechCrunch, Apple says that it has done internal
testing and gathered customer data to determine the performance difference
between the two chips in the iPhones.
在一份给TechCrunch的声明稿中，苹果表示经过内部测试以及蒐集了消费者的资料。
两种芯片的差异已经有了结果。
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.
我们设计的A9芯片根本是科技的尖端，你拿到的是世界上最棒的手机。
无论你拿哪个型号或颜色，你都可以得到最棒的效能、卓越的电量、快乐的人生。
最近很多人在帮我们做不同制成芯片的电力测试，喔，拜托，谁会那样测。
现实生活有谁会拿着手机24小时不断的让CPU满载阿。根本一点也不现实。
在一般日常使用下，电力只会差2~3%啦。
Apple says that early battery benchmark tests conducted by customers,
such as those weshared yesterday, are not reflective of real world usage
conditions. The two to three percent difference that Apple has seen in data
gathered from customers is "well within its manufacturing tolerances" and is a
level of variation that could be seen between two devices with the same chip.
Apple's statement on real world usage reflects what recent YouTube tests have
revealed. Side-by-side battery tests comparing a TSMC iPhone and a Samsung
iPhone did not show differences as dramatic as benchmark tests have shown,
but those videos are also not quite indicative of real world usage results. On the
MacRumors forums, opinions on battery life have been highly mixed. While some
users with Samsung chips have reported poor battery life, others have not
reported issues.
这两段只是做总结，基本上跟前面说的差不多，懒得翻了。
总之，苹果承认两种芯片有差异，但认为这只是公差的正常值。
不要嘘我QQ，我只是在等官网开卖无聊，转贴新闻不是在护航。
