Battery life matters, especially on a device as important as a smartphone, so it’s not at all surprising that folks are starting to take a closer look at the iPhone 6s and 6s Plus.
Interestingly enough, it’s not the battery itself that people are focusing on, but instead the processor equipped in the device. As has already been reported, both Samsung and TSMC manufactured A9 processors for Apple for the new flagships, and there’s a healthy amount of either chip out there in the wild. Unfortunately, some owners are noticing some differences.
Specifically, the iPhone 6s or 6s Plus equipped with a TSMC A9 has the ability to get a few more minutes, or even up to two hours, worth of extra battery life when compared to the 6s or 6s Plus equipped with Samsung’s 10% smaller chipset.
Just recently a pair of YouTube videos showed that, with varied testing, the TSMC A9-equipped iPhone 6s generally had better battery life than an iPhone 6s fitted with Samsung’s A9 processor.
Now, based on a report from Ars Technica and an official comment made to the publication by Apple, the company is acknowledging that there is indeed a difference in battery life between the models. However, Apple says that variation is quite minimal:
“Our testing and customer data show the actual battery life of the iPhone 6s and iPhone 6s Plus, even taking into account variable component differences, vary within just 2-3% of each other.”
Apple, for its part, then goes on to say that the tests that these results are based off are not representative of real world situations. Instead, these tests function to clock the processor to its highest state of performance, obviously taxing the device in ways that wouldn’t necessarily reflect every day usage.
The differences in battery life from one iPhone to the next, based solely on which processor is installed within, is certainly worth looking at, but even with the tests that show the TSMC-equipped models getting more life, the general consensus has been that real world activities, even with moderate usage, the difference in battery life probably wouldn’t get noticed by the general consumer. And, based on Apple’s statement, that’s how they feel, too.
What do you think of all this?
If you like, you can read Apple’s full statement below.
“With the Apple-designed A9 chip in your iPhone 6s or iPhone 6s Plus, you are getting the most advanced smartphone chip in the world. Every chip we ship meets Apple’s highest standards for providing incredible performance and deliver great battery life, regardless of iPhone 6s capacity, color, or model.
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. It’s a misleading way to measure real-world battery life. Our testing and customer data show the actual battery life of the iPhone 6s and iPhone 6s Plus, even taking into account variable component differences, vary within just 2-3% of each other.”
