iOS 9, Apple’s newest update to the iPhone’s operating system, is about to drop.
Apple said that it would be released on September 16, but not precisely when. However, previous years suggest that it will come through an update at 10am Pacific Time.
The company tends to release all of its updates, and start all of its events, at that time. It has occasionally pushed them back slightly, but that time is likely the safest bet.
If the update is launched at 10am local time, it will be available at 6pm in the UK, 1pm in New York and 1am in Shanghai. For a full list of times around the world, you can head to this site.
Apple doesn't announce when the new updates are released, instead just pushing them out to users through the settings app. Checking whether it has arrived yet is done by going to Settings and clicking through to "Software update", where a message to download and install will appear.
Those initial downloads might be slow or not work at all, since Apple's networks are often overloaded in the hours after the update comes out.
Notifications and reminders are usually sent out soon after. But Apple staggers those presumably so that load on its servers is reduced.
iOS 9 brings a range of new features, many of them small fixes and tweaks to the operating system. You can read The Independent's full review of the operating system here, and our guide to preparing your phone for the update here.
The new operating system is being released just ahead of the iPhone 6s, which comes out on September 25 and was launched at an event earlier this month:
