Apple iPhone

First spotted by Italian Blog Mobile World, a potentially new severe bug affects not only iPhones but also a wide range of Apple devices, including iPads, Macs and even Watch OS devices running the latest versions of their operating software.

Like previous 'text bomb' bug, the new flaw can easily be exploited by anyone, requiring users to send only a single character from Telugu—a native Indian language spoken by about 70 million people in the country.

The tech giant sold 45.51 million iPhones in the three months to 24 September, beating an average estimate of 44.8 million.

The company also forecast higher-than-expected holiday season revenue of between $76bn and $78bn.

But revenue in the fourth quarter fell 9% to $46.85bn.

That meant annual revenue fell for the first time since 2001, highlighting a slowdown in the smartphone market as well as intensifying competition, particularly from Chinese rivals.

These are 11 not-so-weird tricks you could have a phone that no longer shuts down as you leave the office, but hangs in there just long enough.

1. Try using the Low Power mode

An exact rollout date has yet to be confirmed, but this update is already shaping up as one of the most substantial 'point' patches in recent times.

More than a simple bug fix, Apple hope to bring a number of new features that will enhance the overall user experience. From sleeping better at night to securing your note-taking, here's what you can expect from the imminent iOS 9.3 update.

1. Night Shift will help you sleep at night

According to Chinese site MyDrivers (via AppleInsider), the colourful iPhone 5C follow-on will forego the widely expected iPhone 6C moniker, and instead be dubbed the iPhone 5E when it makes its way to retailers early this year.

Confused? Well so are we. According to the unnamed insider sources, however, the unconventional naming switch would see the "e" stand for "enhanced".

It has been suggested that the phone will stick with the outdated numerical name due to its smaller 4-inch form - something the 4.7-inch iPhone 6 left behind in 2014.

Figures from price comparison and switching service uSwitch suggest that no fewer than six of Britain's top ten bestselling handsets were iPhones this year.

And six was the magic number for Apple as the 16GB model of the iPhone 6 outsold the rest in 2015, followed by the 2-year-old iPhone 5S.

The 64GB version of the iPhone 6 came in third, with the base model of this year's iPhone 6S in fourth place.

The figures make bleak reading for Samsung, as its flagship Galaxy S6 only just cracked the top five, its 32GB incarnation pushing the iPhone 5C into sixth.

That's what many will be saying after Apple surprised the smartphone industry with the release of its own $1

Invites were sent Thursday that read "Hey Siri, give us a hint," referring to the personal digital assistant available to owners of Apple mobile devices. (Alas, Siri offers only cryptic replies such as, "Why don't you check a rumors blog? That's what I do." and "You're cute when you're desperate for information.")

The new phone is expected to feature enhancements including the force touch display, a better camera and a faster processor.

Apple may also unveil a new version of the iPad -- a 12.9-inch "Pro" model, according to a report by John Paczkowski of BuzzFeed.

A company spokesman declined to comment.

Sure, it can do many useful, even delightful things, such as showing incoming texts and email, tracking heart rates during exercise or sending digital doodles to friends. But is that enough to spend $350 or more, especially when it requires wearing a watch again while still carrying an iPhone around?

Early Apple Watch owners seem generally happy with it, but Apple's bigger worry should be those on the sidelines - even hardcore Apple fans, not to mention everybody else - who are waiting to take the plunge.
