Over the past couple of days, reports have been spreading that suggest iPhone 6s and 6s Plus smartphones that use a Samsung-made Apple A9 SoC feature worse battery life than devices that contain a TSMC-made A9. The discrepancy has reportedly been as large as 2 hours in GeekBench’s battery test, which is pretty significant for two devices that are supposed to be identical
According to Apple, though, the differences in SoCs produced by TSMC and Samsung are nothing to worry about. In a statement regarding the matter, an Apple spokesperson said that the “actual battery life” of the iPhone 6s line varies “within just 2 to 3 percent of each other… even taking into account variable component differences”.
The company went on to suggest that the battery life figures reported by some “are not representative of real-world usage,” since the benchmarks are too processor heavy and “misleading” to measure real-world battery usage. In short, according to Apple, consumers shouldn’t worry about whether their iPhone comes with a TSMC or Samsung SoC.
