内置芯片影响6s电池寿命
Inside the sleek body of the latest iPhone is one of two chips made by different manufacturers.
最新款的苹果手机光滑的机身里，有由不同厂家生产的两种芯片之一。
After conducting tests, a number of iPhone users have claimed the battery life differs on the iPhone 6s depending on which chip is inside.
But Apple has said these tests are 'not representative of real-world usage,' claiming the battery life of 6s handsets varies within just two and three per cent.
Commentators have branded the issue 'chipgate'.
It has long been rumoured that the A9 chips inside the popular new iPhone 6s and 6s Plus handsets are made by two manufacturers - TSMC and Samsung - and teardowns recently confirmed this.
A number of benchmark tests claim to show a theoretical difference in battery life depending on which A9 chip was tested, with one claiming a 50 minute difference between manufacturers.
Tests first posted on MyDrivers showed that TSMC's chip out-performed Samsung's according to reports on BGR.com.
YouTubers Austin Evans and Jonathan Morrison then both claimed to show that TSMC's chip is slightly more efficient.
Apple told MailOnline that its own testing, as well as data gathered from its customers since the handset launched, shows the battery life of the handsets varies between two and three per cent.
This is regardless of the chips inside them.
The firm said: '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.
