| Battery life in Apple iPhone 6S models can vary by some 3 per cent, according to Apple |
NOT all iPhones are created equal. And some lucky customers get better battery life than others, Apple has confirmed.
The battery life on your new £539 iPhone 6S or iPhone 6S Plus is the result of a lucky – or unlucky – dip.
A slew of online tests released over the last week appear to prove a massive disparity in performance and battery life in the new iPhones.
Apple has now addressed the backlash – dubbed chipgate – and confirmed that users will experience some minimal differences between iPhone models.
A spokesperson for the Californian firm said: "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 to 3 per cent of each other."
That's a lot less than the 20 per cent difference between iPhone models recorded by a prominent online test.
A slew of angry Apple fans this week reported losing two HOURS of battery life in their iPhone 6S when compared to a model powered by a different chip manufacturer.
The unsubstantiated forum posts claimed Apple smartphones running the A9 chip built by TSMC can eek a few more hours battery life from their handset.
The TSMC chip was also shown to run much cooler than its Samsung alternative in a number of online tests.
Apple has not revealed which chip is responsible for the extra 2 to 3 per cent of battery life.
The US technology giant claims the iPhone 6S has some 14 hours of talk time on 3G. Meanwhile, the iPhone 6S Plus has around 24 hours.

Chipgate is the first backlash to hit the problem-free launch of the iPhone 6S and iPhone 6S Plus, unlike the bendgate scandal which hit its predecessor.
Apple sold a staggering 13 million smartphones during the launch weekend – a new record for the company.
Both smartphones have received rave reviews – including our own, which dubbed the pressure sensitive 3D Touch display "revolutionary".
The full statement from Apple on its A9 reads: "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, colour, 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."
If you still would like to find out which manufacturer's chip is powering your shiny new iPhone 6S, there is a free app which reveals all.
Lirum Device Info Lite is available from the App Store. Launch the software then make a note of the model number, which dislays on the main page.
If you have an iPhone 6S or iPhone 6S Plus, model numbers N66AP and N71AP mean you are running a Samsung chip with supposed lower battery life.
Meanwhile, N66MAP or N71MAP denotes the TSMC – and a few more hours of juice.
