iPhone 6 vs iPhone 5S: Battery
With such a boost in screen size the iPhone 6 inevitably needs more power, and so Apple has equipped it with an 1,810mAh battery. That's a fair bit bigger than the 1,560mAh battery in the iPhone 5S, but it's still significantly below your average Android smartphone. For example, the Galaxy S5 has a 2,800mAh battery.
Apple will have done some work to optimize the hardware and deal with power management efficiently, but it has been a weak point for the iPhone 5S, so the iPhone 6 really needs a bit more stamina. Apple claims it equals or beats the iPhone 5S battery on everythingWe'll have to get a real world hands-on to really assess it.
iPhone 6 vs iPhone 5S: CPU / RAM
A vital component in the fight for power efficiency comes in the shape of the new A8 processor. This is a serious jump for the iPhone 6 over the iPhone 5S. Apple says the CPU is 20% faster. It's also more efficient and it enables a much faster response time and more demanding graphics rendering.
Apple seems to have decided that the 1GB of RAM in the iPhone 5S is sufficient for the iPhone 6, but that's not been confirmed yet.
iPhone 6 vs iPhone 5S: Health
Fitness is big business and it's driving the wearable technology market right now, so it makes sense that Apple has added some new sensors to the iPhone 6 to take advantage of the new Health app in iOS 8.
The iPhone 6 is equipped with a range of sensors to measure your health and fitness, accurately tracking your heart rate, calories burned, and your sleep patterns. It should give a more accurate picture of your health than the iPhone 5S and help you to stay in top condition.
iPhone 6 vs iPhone 5S: Price
The iPhone 6 starts at $199 (around £123, AU$216) for the 16GB version and goes up to $399 (around £248, AU$433) for the 128GB version on a two-year contract. The iPhone 5S has been discounted by $100 to make way for the new release.
We expect you'll be able to pick up the new iPhone 6 for no money down on a two-year contract for around £40 per month in the UK. If you're sold then you can get your hands on the iPhone 6 from September 19. The iPhone 6 also boasts faster Wi-Fi and LTE.
