iOS 9 launch: Stampede for longer battery life leaves some Apple fans locked out
Apple has launched the latest version of its operating system, which offers iPhone and iPad users a longer battery life.
The free update, named iOS 9, suffered from teething problems after a large number of customers tried to download the program as soon as it was released.
It meant Apple fans were either blocked from downloading iOS 9 or faced hours waiting for it install.
Those who managed to get their hands on a working version enjoyed a new low-power mode that will reduce or turn off non-essential tasks such as visual effects and automatic downloads. The phone also won’t check for new mail or update content for apps in the background as often.
Apple said this will add an extra hour to the device’s battery life, in a bid to solve one of the biggest complaints about the US company’s products.
Apple’s personal digital assistant has also been given a makeover. Siri will now offer more comprehensive results when asked to search for music, films or sports results, or your pictures and videos.
For example, if you listen to music on your way to work, Siri is likely to suggest you use your favourite music app at the time you start your commute.
Meanwhile, new multi-tasking features allow iPad users to use two apps at the same time using a split-screen or “picture-in-picture” function.
The new viewing modes have already been adopted by some of the best-selling apps in Apple Store. The BBC’s iPlayer app now offers picture-in-picture support, so you can write an email while watching EastEnders, for example.
For people in London, an update to Apple Maps will reveal where Tube entrances are, improving directions to and from public transport.
The iOS 9 update will work with the iPhone 4s and any model made after that, and the iPad 2 onwards - as long as your device has 1.3GB of free space.
However, the update for the Apple Watch - watchOS2 - has been delayed due to a bug in its development.
