There’s no shortage of speculation about what will be included in the next iPhone, much of which seems to be based on wishful thinking:
A Liquidmetal shell: As Apple strives to make the new handset as slim and strong as possible, some commentators have speculated that it may turn to Liquidmetal, an alloy that’s stronger than aluminium. In theory that would mean the handset could be lighter and slimmer without skimping on strength or build quality, but in practice it seems unlikely. Although one of the inventors of Liquidmetal predicted two years ago that Liquidmetal cases would be possible by mid-2014, its use has so far been limited to small components.
Liquidmetal components: This is much more likely. Documents published by Apple-watching website MacRumors, suggest that the alloy could be used in buttons and switches in order to toughen up what have often proved to be weak points on previous iPhones.
A curved screen: At the end of last year Bloomberg carried a report predicting the next iPhone models would have screens that curved down at the edges. Curved screens are said to be more durable, more comfortable to use, and better suited to watching videos and playing games, according to Sky News. This would be a bold move for Apple, which usually likes to stand back and see how other phone-makers fare with new, risky technologies – and more recently a source told The Wall Street Journal that Apple has no plans to make use of curved glass. However, despite all the leaked images apparently showing the iPhone 6 with a flat screen, rumours of curved glass have resurfaced, most recently in the Daily Mirror.
Quantum dots: This is probably a technology for future handsets, not the iPhone 6. Patent filings suggest Apple is experimenting with tiny crystal semiconductors just a few thousandths of a millimetre across, which could improve the colour and sharpness of mobile screens. “The techniques Apple describes would let its screens not only show colours more accurately,” Business Insider says, “but also show a wider gamut of colours.” The publication had predicted in March that the quantum-dot screen may be ready this year, but no further reports of the technology have emerged.
Battery life: Mixed signals have emerged about the iPhone 6 battery life. On the positive side, analysts have pointed to iOS 8, Apple’s new operating system, and its new A8 processor as evidence that the company is paying more attention to power consumption. The chip, says 9to5Mac.com “adds significant performance and efficiency enhancements in order to improve the iPhone’s battery life”. On the other hand, more recent reports suggest that the slim frame of the new phone has forced Apple to adopt a battery that is just 2mm thick. Taiwanese sources suggest that the new battery has a “similar capacity” to its predecessor, which may dash hopes of significantly improved performance.
Optical image stabilisation: MacRumors says the bigger of the two iPhone 6 models “may include camera improvements in the form of optical image stabilisation with modules produced by sensor company InvenSense”. Camera performance is becoming increasingly important at the top end of the smartphone market, and analysts suggest that optical stabilisation, which reduces image blur, could help to justify a larger price tag for the 5.5-inch iPhone 6.
Eye-tracking: Some rumours suggested that the iPhone 5S would be eye-controlled, allowing users to scroll through pages without touching the device. When the technology failed to materialise in the last model, hopeful observers shifted their attention to the iPhone 6.
NFC: Another long-predicted feature, Near Field Communication or NFC would allow the phone to act as a payment system. Users would wave their handsets over a receiver to transfer money in shops and restaurants, or between friends. Several Android and Windows Phone devices already support NFC payments, but Apple has yet to make the leap.
Studio flash: Apple is working on a way of letting iPhones control flashes built into a range of phones and tablets in order to light a scene from multiple angles, according to Apple Insider, which unearthed a patent for the system. There’s no hint about when the system might make it into production
Health monitors and apps: Apple has already unveiled its new operating system, iOS 8, and what we’ve seen so far suggests that Apple is turning its attention to health and fitness. Smartphone accessories such as the Fitbit and FuelBand have proven the demand for health-monitoring devices, and reports suggest that the iPhone 6 will be able to keep track of its owners pulse and body temperature, as well as other metrics. These features may work in conjunction with the long-awaited Apple iWatch.
