Apple’s Responds to A9 Chipgate issue regarding battery life

iPhone 6s Battery Life

In the past few weeks many organizations started comparing Samsung made vs TSMC made Apple A9 chip, and almost all of them found TSMC Made A9 chip to be much better than Samsung. We posted an video earlier about the battery life comparison of two different iPhone 6s (using different SoCs), and iPhone 6s with TSMC chip lasted longer than Samsung made chip. TSMC made Apple A9 chip also did well in iPhone 6s benchmark test (performance test). There were not much difference in the score, so users didn’t bother much about it, but battery test must have made many users sad.

iPhone 6s features 1715 mAh battery only compared to 1810 mAh that Apple used in iPhone 6. However, iPhone 6s battery test proved how optimized Apple A9 chip is, as it lasted much longer than iPhone 6. Apple probably used two manufacturers to produce A9 chip to fulfill the orders. iPhones are always in demand, and going out of stock may have bad impact on business as well as customers.

According to Apple, after few weeks of iPhone 6s launch, based on data collected from various customers, we found only 2 to 3 percent difference in battery life while comparing both iPhone 6s models (one using Samsung made A9 chip and other TSMC). So 2-3 percent doesn’t have a real effect on daily usage.

Apple gave these statement to TechCrunch about iPhone 6s battery life issue (A9 ChipGate Issue)

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.
