Apple says A9 chip-maker only affects iPhone 6S battery life by 2-3%

iPhone 6S

Apple has responded to a growing number of reports suggesting a discrepancy in iPhone 6S battery life, depending on which of its suppliers builds the A9 processor.

Independent tests have claimed the version of the A9 chip supplied by TSMC can enjoy anything from 6 to 22 per cent longer life, compared with the Samsung-created chip.

However, Apple has responded by claiming the real world difference is unnoticeable as it falls within 2-3 per cent.

The company claimed the ‘misleading’ lab tests conducted were not indicative of real world usage as they spend ‘unrealisic’ amounts of time maxing out the CPU.

In a statement given to TechCrunch an Apple spokesperson wrote: “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.”

So there you have it, you don’t need to go cracking open your new iPhone 6S to see who built the A9 processor. Well, if you take Apple’s word for it.
