APPLE HAS RELEASED the third update to iOS 9 to fix a number of vague security bugs.
Version 9.2.1 is available to download over-the-air or via iTunes. The update will work on any device that supports iOS 9, i.e. the iPhone 4S and newer, the iPad Pro, the iPad 2 and newer, every iPad Mini, and the fifth- and sixth-generation iPod Touch.
Apple has been quite vague about the bugs that the security update fixes in iOS 9.2.1 but did mention that it includes "a fix for an issue that could prevent the completion of app installation when using a mobile device management server".
Those hoping that Apple has fixed the dreaded battery bug problem, which has been reported by owners of iPhone 6S and iPhone 6S Plus handsets, will be disappointed, as Apple has said it is still looking into the problem.
The fault stops an iPhone's battery percentage level updating, fooling users into thinking that they have more juice left than they actually have. It has affected Apple's latest iPhones since they were released in September.
Apple's support forum is full of complaints about the fault. "My iPhone 6s Plus battery percentage gets stuck frequently. Like for example, it will say 87 percent all day, and then I'll plug it in for an hour and it will still say 87 percent," one user moaned.
"The only fix I've found is to power the phone off and then turn it back on. Then the percentage will update correctly, and will usually continue to update properly for a while. But, eventually, it gets stuck again."
Another whined: "I have a new 6S and maybe five times or so I've had the battery percentage stick on me. There is no problem charging the device and it doesn't drain quickly. Much like you, the percentage will stay at a random number."
Apple said in a support document: "If you change the time on your iPhone 6S or iPhone 6S Plus manually, or change time zones when travelling, you might notice that the battery percentage doesn't update. Learn what to do."
The firm has offered a quick fix for affected handsets. Firstly, restart the iPhone 6S or iPhone 6S Plus, and then head to Settings > General > Date & Time and make sure that Set Automatically is switched on.
This isn't the only problem to hit owners of the iPhone 6S. 'Shutdowngate' first made headlines in October when Apple's latest iPhones started switching off for no apparent reason. µ
