Apple's annual iPhone product launch on Tuesday marks the 10th anniversary of the iPhone. As always, the suspense is mounting but this year, if the rumours are to be believed, it is set to be the most exciting launch since the iPhone 5S was revealed.
Here is what sources say we can expect from Tuesday's Apple launch event:
iPhone 8 and iPhone 8 plus:
Launched in honour of the device's 10th birthday, the iPhone, which could be called the iPhone X, iPhone Pro or iPhone Edition, is expected to have an edge-to-edge screen, no home button and glass back. What is bound to be the star of the show will be this next-generation iPhone with its all-new design.
The flagship device is expected to cost $1,000 in the US, and possibly more than £1,000 in the UK (typical). It is likely to come in three colours - white, black and copper - and run iOS 11.
Apple is rumoured to have ditched the home button and Touch ID on the device to make way for the larger screen. It will replace the fingerprint sensor with facial recognition technology that can recognise the owner, according to reports.
The iPhone 8 will also feature new augmented reality uses, iPhone-to-iPhone payments and come with wireless charging, reports suggest.
iPhone 7S and iPhone 7S Plus:
In addition to the iPhone 8, Apple will probably upgrade its current handsets, possibly under the name iPhone 7s and 7s Plus. Tradition dictates the new devices will have faster processors, improved battery life and minor enhancements such as better cameras. They will be cheaper than the iPhone 8, probably costing close to the £599 and £799 of the iPhone 7 and 7 Plus.
Every year Apple releases a new software alongside its latest smartphone. This year, it is iOS 11, which includes iPhone-to-iPhone payments, a re-designed control centre and Siri translation. ARKit, Apple's new developer software for augmented reality, will most certainly get people excited.
iOS 10 went live on September 13th 2016, three days before the iPhone 7 went on sale. If Apple is working towards the same timeframe, iOS 11 could be available from September 19th 2017.
The Apple Watch 3 could be a standalone device of its own with connectivity provided via a simple card. This should enable some calls and messaging, without being connected to an iPhone.
In June Apple announced is Siri-controlled HomePod speaker. We were told it would be released by December 2017 and would cost $349. We were left with a few unanswered questions, around its connectivity options and if it would support phone calls. We will be listening out for more updates on this one.
4K Apple TV:
There have been talks of a much-anticipated update to the Apple TV which has been left on the shelf since 2015. It's touted to support 4k streaming and HDR video and should run to under £200.
“Apple have become the masters of segmenting a portfolio into very distinct price tiers,” said Geoff Blaber, analyst at CCS Insight.
Analysts believe the launch will help Apple to overcome its growth problem of the last two years. In markets such as America and Europe, where smartphone ownership is close to saturation and many customers are holding on to their existing handsets for longer, the best way to drive faster revenue growth is by charging more for each device, rather than simply relying on unit growth.
