There is another controversy that is now doing the rounds on the internet about the new iPhone 6S that Apple has launched recently. This one has got to do with the hardware of the iPhone 6S and nothing to do with the software like earlier. There are some users claiming that the battery life of the iPhone 6S varies depending on the processor that is used in the phone. The phone’s battery life is different for a TSMC made processor or a Samsung processor.
Apple has immediately come out with a clarification in order to nip this rumor in its bud. Apple has said that the battery life between the two identical iPhone 6S and the iPhone 6S plus will vary, but just by negligible 2% or 3%. There will not be any exaggerated difference in the battery life as the rumors are suggesting.
The A9 processor used by Apple on its new iPhone 6S and 6S Plus is developed by two manufacturers, Samsung and TSMC. The two chips from these manufactures are different in size with Samsung’s chip measuring 96 mm (made to 14nm process) and the 104.5 mm TSMC chip (made in a 16nm process). The user does not have the option of choosing the chip of the iPhone 6S or 6S plus when making the purchase.
There are reports that have come out that the iPhone 6S working on the TSMC’s A9 chip processor has a better battery life than the iPhone with the Samsung A9 chip. The third party tests conducted by GeekBench and AnTuTu revealed that when the phones worked under high loads to offer its best performance, the TSMC processor in the iPhone was able to offer 2 hours of extra battery life than the Samsung powered phones.
Apple said that the real world usage of the iPhone is the right way to judge the performance of the battery and not through the benchmarking tests. The phones will just show a normal variance of 2 to 3 percent between two iPhone 6s handsets, which is inside the margin of error guidelines.
Apple said that the variance of the battery life between the Samsung powered or the TSMC powered iPhones is just 12 to 15 minutes. Even though the TSMC chip is better than the Samsung A9 chip used in the iPhone 6S, there is no way that this small variation could make a world of change to the end user.
