How to free up space in iCloud

Apple's iCloud storage service can be used to stash
away photos, videos, device backups, and more in the
cloud. The company offers users 5GB of space for free,
however because it's 5GB of space per Apple ID and not
per device, you may find yourself running out of space
faster than you would like. While additional storage can
be purchased from Apple, there are ways to free up
space in your iCloud account.
Check your space
To see how much space you are using, enter Settings on
your iPhone or iPad, select iCloud , click Storage &
Backup, followed by Manage Storage .
Delete old backups
There is a good chance that your backups are taking up
most of your space. If you have backups from your old
device, say from an iPhone 4 or iPad 2 that you no
longer own, you can just go ahead and delete those.
Simply click on the backup scroll to the bottom and tap
Delete Backup .
Change backup settings
You may have also backed up things in your most recent
backup that you didn't really need to have saved in the
cloud. If this is the case, click on the most recent
backup and scroll down to see all of the backed up
data. If you find something you really don't care about,
flip the switch to off to delete the data. This will also
make sure it isn't backed up the next time you perform
a backup.
Alternative photo services
An easy way to free up a ton of space in iCloud is to
delete photos from your backups. Instead of having
photos stored in iCloud, I recommend using one of the
many third-party cloud services that offer even more free
space than Apple. There is Yahoo's Flickr app, Microsoft
One Drive, Google+, DropBox and Amazon Cloud Drive,
and many others. Check out this article for more
information .
There is also your iCloud Photo Stream. While this
doesn't actually take up space in iCloud, photos are
only stored on Apple's servers for 30 days. If you end up
using one of the other cloud services to store your
photos, I recommend disabling the iCloud Photo Stream
feature. This can be done by going to Settings, clicking
on iCloud , selecting Photos and flipping the My Photo
Stream switch to off.
