Apple dismisses iPhone 6S battery concerns

The iPhone 6S and iPhone 6S Plus feature Apple's new A9 processor, but it's being sourced from two companies: TSMC and Samsung. Some users were naturally curious if there would be a difference in battery life between the two.

Reddit user raydizzle posted that they have two iPhone 6S Plus handsets, one with a TSMC chip and the other with a Samsung chip. They performed a GeekBench battery test for both and found that the TSMC chip lasted eight hours, two hours more than the Samsung chip.

Apple has dismissed these concerns however. In a statement released via Ars Technica, Apple said that the battery life performance between the two chip types in "real-world usage" doesn't vary all that much.

"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% of each other."

It highlighted flaws in benchmarking, as certain tests which "run the processors with a continuous heavy workload until the battery depletes are not representative of real-world usage." Apple went on to say that "It's a misleading way to measure real-world battery life."

The iPhone 6S and iPhone 6S Plus is now available in Ireland. And according to Apple, you can rest easy that your handset's battery life will be comparable to everyone else's, regardless of where your model's A9 chip was sourced from.
