iPhone 6S SoC source has no major impact on battery life

There's been some concern among Apple fans that battery life of the iPhone 6S could be heavily dependent on the source of the phone's A9 SoC. As you may know, Apple is dual-sourcing the production of its chip to Samsung and TSMC, and this has resulted in speculation that there could be a major difference in power eficiency.

Apple denied this rumor, claiming the actual battery life of its iPhone 6 series defies varies within just 2-3 percent of each other. Consumer Reports decided to investigate the "chipgate" problem and found there's no significant different in battery life or temperature.

The site did a number of tests and found the performance difference of the TSMC-made and Samsung-made SoC was less than 1 to 2 percent, depending on the test:
Bottom line: Smartphones are as complicated as the people who use them, so it’s impossible to say with certainty that the battery- and temperature-performance differences we measured in this chipgate testing will be consistent in every imaginable scenario. But if iPhone 6s users are ever disappointed with their phones, we’re confident it won’t be because they bought the model with the “wrong” chip.
