A few days ago, it was revealed that the A9 chip in Apple’s new iPhone 6s is manufactured by two different companies, Samsung and Taiwan Semiconductor Manufacturing Co (TSMC). More notably, reports started circulating that the battery life in the Samsung A9 devices was notably worse than that of the TSMC iPhones. Some tests have revealed that the TSMC chips last as much as two hours longer than the phones with Samsung silicon inside. Now, Apple has issued an official response that downplays the difference as only a matter of a few percentage points.
“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 to 3 percent of each other,” Apple said in a statement. The company refuted testing done in the lab by third parties, calling them “manufactured” because they use unrealistic parameters. Those tests “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,” Apple added. This is typical for both current and past Apple products, and reflects across all phone types, meaning it does not matter which company manufactured the A9 chip, Apple clarified.
The new iPhone’s battery performance was hardly cited by mainstream gadget reviews, with many seeing similar performance to last year’s model. Apple considers it an engineering feat to maintain battery life year after year, as it’s increasing the performance with its new A9 chip and, in the case of the iPhone 6S, doubling the amount of memory under the hood. Still, Apple believes that regardless of who made the A9 chip in your iPhone 6s, you should get battery life in line with what the company claims — and if you don’t, chances are good the company will simply swap out your phone for a new one.
