This means it can transfer information around compatible Wi-Fi networks at speeds up to 430Mbps, and brings it in line with the latest smartphones from Samsung, HTC and Sony.

There’s a new Wi-Fi calling feature that starts your call on Wi-Fi and hands off to cellular networks once the signal strength improves. This will starting with US carriers.

Also, there’s support for LTE Category 4 with carrier aggregation, which is a faster mobile network standard that’s beginning to appear in Australia, starting with with Vodafone.

A maximum transfer speed on a Cat 4 network is 150Mbps, so this is certainly a good thing. Twenty LTE bands are now supported, compared to the iPhone 5’s 13 bands.

VoLTE, or Voice Over LTE is also included, but we haven’t seen this feature supported by Australian telcos yet.

The iPhone 6 also marks the inclusion of the long-awaited mobile wireless payment technology called NFC, or Near Field Communication.

This, in combination with the Fingerprint ID sensor, and a new security chip, should help drive adoption of mobile payments using your phone, rather than your credit card.

The larger batteries in the iPhone 6 models will be a welcome addition to many.

While Apple hasn’t said exactly what the battery sizes are, we suspect the 4.7in model will get the rumoured slightly higher capacity 1,810mAh, a small increase over the 1,560mAh battery in the iPhone 5s, while the the iPhone Plus gains the rumoured considerable bump to a 2,915mAh version, though we’re checking with Apple to see if we’re on the money with both.

Claimed times are 14 hours talk and 10 days standby for the iPhone 6, while the iPhone 6 Plus apparently manages 24 hours talk and 16 days talk-time, but this will be different in real life depending on how heavily the phone is being used. Apple also quotes 1o hours of LTE browsing time for the iPhone 6 and 12 hours for the Plus.

On the memory front, the iPhone 6 provides 16, 64 and 128GB choices, with the iPhone 6 Plus following suit. Seems that 32GB has been dropped.

The new iPhones come loaded with Apple’s latest iOS 8 operating system, which includes many enhancements and new features.

Where, when and how much?

Following Apple tradition, the iPhone 6 and iPhone 6 Plus will be available 10 days from launch in the US, and Australia is one of the international launch countries that will also see the phone appear in shops on the 19th of September.
