Many of us still remember the iPhone 6 Plus bendgate last year, where phone bends because of low quality material for a big bar phone. Apple worked hard and introduced a high-class Aluminum this time to overcome last year’s issue but it looks there are other demons are not letting it rest. Now a new controversy has emerged related to Apple’s new iOS Devices. Apple has used a new A9 processor for this year’s iPhone 6S and iPhone 6S plus. A teardown expert Chipworks originally reported that Apple has two models of the CPU in the new iPhones. The Smaller chip is made by Samsung and slightly larger chip made my TSMC.
The Samsung device is made on a 14nm process, while TSMC chip is made on the 16nm process.
Chipworks said “For Apple to go through all the trouble of dual-sourcing a custom designed part and launching on day one with both parts, suggests major sourcing problems. For cost and power reasons, there is little reason to run a larger die, unless the smaller die was not available at the right volumes,”
The below YouTube Video by user Austin Evans, compares the performance of the battery between the Samsung-chip iPhone and TSMC-chip iPhone. It surprising that TSMC powered iPhone shows a longer battery life. Evan uses an application called Lirum from the apple store which let you know the version of iPhone.
To contrast the claims made for Chipgate, Apple has released an official statement
“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.”
So according to the people making iPhones, the people testing the devices aren’t accurately re-creating “real-world” circumstances because they are applying unrealistic stress to the CPU. Your phone’s guts aren’t likely to be cranked up that high for so long in day-to-day use, so these kind of stress tests aren’t the best way to compare, Apple says.
