Lost Mode can also attempt to track the device - but can only do so when it's online with Internet access, so it's best to activate location sharing whenever possible for maximum security.
iCloud storage: free 5GB
When you create an Apple ID account you automatically get 5GB of free storage on iCloud, which you can use to store your photos, emails, and your device backups. That's not a huge amount, but the music, videos and apps that you buy from iTunes or the App Store don't count towards the 5GB total, so most people can still get by with that basic amount of storage. I use my iPhone and iPad all the time, and I've still got about 4GB spare. If you want to know how much storage you have left you can see it displayed near the top of the main iCloud settings panel.
But, as iCloud adds more new features, such as iCloud Drive and iCloud Photo Library, it gets easier and easier to fill up that 5GB of storage. Fortunately, you've got a couple of options for managing your iCloud storage, which you can see just by tapping on Storage in the settings panel.
Manage iCloud storage: Get more space in iCloud
The Storage Panel shows you how much storage you've got left (above). If you take a lot of photos, or use iCloud Drive to store a lot of work files then you might need to pay for some extra storage. However, there's another option that you can try first. Just tap on Manage Storage and you'll see a detailed list of everything you have stored in iCloud. Your Photo Library comes first, followed by back-ups from all your iOS devices, and then a detailed list of all the files created in other apps such as Keynote and Numbers (below).
I recently moved a load of holiday photos back onto my office Mac, so the Photo Library on my iPhone currently only takes up about 190MB. My iPad backup is bigger, though, taking up 200MB, and there's a number of files that I created in Keynote on my Mac that take up another 190MB on their own. If you're close to your 5GB limit you can see which apps and files are taking up the most space and you might be able to grab back quite a bit of space simply by deleting a few old files that you don't need anymore.
Manage iCloud storage: Remove data from iCloud to make more space
You actually have really fine control over the data that you store in iCloud. Of course, you can delete individual photos and videos from Photos whenever you want, and it doesn't hurt to clear out your email Inbox now and then either. You can also delve into iCloud and delete files from other apps too. Just tap on the name of any app in the Manage Storage panel, and you will see a list of every single file created by that app, along with the size of each file. I wrote an article on Keynote for MacWorld recently, and I've still got a number of large Keynote presentations files that are taking up space in my iCloud storage. But if I tap the Edit button at the top of the screen I can delete individual files that I no longer need, or just use the Delete All command to delete every file created by Keynote.
