iPhone 6S: Apple says A9 chip performance varies by just 2-3%

Apple has moved to counter claims that battery life between different iPhone 6s models varies wildly depending on whether the device uses a TSMC or Samsung–made A9 chipset.

A string of benchmark tests have caused widespread consternation among tech-watchers, after they appeared to reveal that TSMC’s chip outstripped Samsung’s and gave users an extra 22% battery life.

While the chipsets are made to the same specifications, it’s been argued that Apple has not done enough due diligence tests to check whether they really match up.

Now Cupertino has hit back, releasing a statement saying that variation is only around 2-3% and that this sits well within normal limits.

Apple stated: “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.”

Apple’s data comes direct from users, who share diagnostic data when they set up their iPhone 6s. That suggests that its tests are more accurate than those looking to find fault with the newly released handset.

However, expect testers to hit back and do their own studies over the next few days. Either way, the iPhone 6s’s launch is beginning to be dogged by the same sort of niggles that surrounded last year’s iPhone 6 release.
