Apple Responds to TMSC and Samsung A9 Chipgate

Apple responds to the growing discussion about the battery life and performance issues between TMSC and Samsung made Apple A9 iPhone 6S CPUs.

The discussion about the difference in performance and battery life between Samsung and TMSC made A9 CPUs in the iPhone 6S got to big for Apple to ignore. The company has issued a statement with a response to the so called chipgate controversy. Apple basically says that there is no difference and the tests circulating on the web are misleading.

The main issue is that the test showing big differences run the A9 on peak performance. This situation is not typical for everyday use of the iPhone 6S.

Despite Apple's statement the discussion will not end. The impact for iPhone 6S owners is marginal. It does not make necessarily make sense to prefer a Samsung over a TMSC or vice versa. The next iOS 9 update could totally change the behavior of both chips.

Full Apple statement via ArsTechnica:

"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."

To find out which A9 CPU your iPhone 6S runs on, an app like Lirum Device Info Lite (free) is required. On the home screen of the app the model number of your iPhone 6S is displayed that gives away the manufacturer of the A9 chip. N66AP or N71AP means Samsung and N66mAP or N71mAP means that the A9 chip is made by TMSC.
