Battery Tests Find No iPhone 6s ‘Chipgate’ Problems ➝

Mike Gikas, writing for Consumer Reports:

A number of websites recently created a stir with reports of a potential shortcoming of the iPhone 6s smartphones. According to those “chipgate” reports, the battery life on iPhone 6s models with an A9 central processing unit made by Samsung is worse than the battery life on models with a CPU made by TSMC. The phones with the Samsung chip also run hotter, the reports claim, than the phones with the chip made by TSMC.

While Consumer Reports’ tests had confirmed that the battery life on the 6s and 6s Plus is slightly shorter than that on the iPhone 6, they had not addressed the chipgate rumors. So, much like they did for last year’s “bendgate,” our engineers developed a special protocol to test this apparent issue. Those tests simulate real-world usage as opposed to relying on the benchmarks used by other organizations in their off-the-shelf tests.

The real-world testing setup they created found much smaller differences in battery life between devices with different chip manufacturers.
