Apple says battery life difference in new iPhones not reflected in 'real-world use'

Whether your iPhone processor chip was manufactured by Samsung or TSMC, Apple says battery life will only vary by 2-3%

Claims that the battery life of the new iPhones can vary by up to two hours depending on which third-party supplier manufactured the central chip don't reflect real-world usage, according to Apple.

The chip at the heart of the iPhone 6s and 6s Plus, named the "A9" chip by Apple, comes in two forms, one manufactured by Samsung and the other by Taiwanese company TSMC. Since the phones started hitting shelves last week, users have reported that the phones containing Samsung chips significantly underperform those with TSMC chips in intensive battery-life tests.
