Yesterday we heard about the difference in battery life on two identical iPhone 6S handsets, each one with different A9 processors, one with a TSMC processor, the other with a Samsung processor.
Now Apple has given TechCrunch an official statement about the issue, Apple has said that data gathered from its users shows that there is a difference in actual battery life of around 2-3%.
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.
According to Apple this is withing normal manufacturing tolerances, the company also mentioned that its data is from every day usage of the new handsets and not data from testing. Have a look at our iPhone 6S vs Samsung Galaxy S7 comparison.
