Apple hit back on tests that claim a difference in iPhone 6s battery life between models having an A9 chip made by Samsung and TSMC.
"A number of tests shared over Reddit and corroborated by tests posted on the MacRumors forum show that the battery life of the TSMC-based iPhone 6s significantly surpasses that of the Samsung-based phone," Tech Times reported.
Reportedly, iPhone 6s models with a Samsung-made A9 chip get less than two hours of battery life than their TSMC counterparts.
To this end, Apple countered the claims and said that the testing done by users using benchmarking apps were "a misleading way to measure real-world battery life."
"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," the Cupertino tech giant told TechCrunch.
Franchise Herald previously reported that Apple contracted Samsung and Taiwan Semiconductor Manufacturing Co. (TSMC) to make the iPhone 6s' A9 chip.
According to their own iPhone 6s battery life test, Apple said that even with a chip made by different companies, the differences in power consumption "vary within just [two to three percent] of each other."
As TechCrunch noted, that slight variance is "within [Apple's] manufacturing tolerances for any device."
Gizmodo said the Geekbench test that brought the claim does put a smartphone's CPU through its paces, "thereby exaggerating any power-usage differences between the two processors."
Then again, "there's no good, objective way to measure 'real-world' battery use," as the website pointed out.
It remains to be seen how the TSMC-based and Samsung-based iPhone 6s fair against each other in a real-world battery life test.
Users who want to find out which chip their new iPhone has can download the Lirum Device Info Lite app. Samsung A9 chips are labelled N71AP while TSMC chips are labelled N71MAP.
