Battery life is a serious matter with regards to modern smartphones. Just last week, it has been reported that apparently, there are two manufacturers of the A9 chip for the iPhone 6s and 6s Plus: TSMC and Samsung. This story would have been unremarkable if not for the fact that people have noticed a difference. After some tests, it was found out that iPhone 6s with TSMC A9 chip has better battery life than the Samsung-made counterpart. How do you find out which A9 chip your iPhone 6s / 6s Plus have?
